This article mainly introduces some basic working principles of the automatic winding filter. We hope that through our introduction, we can bring you some help.

Automatic rolling filter has two basic functions, one is automatic mode and manual mode!

In the automatic mode, when the dust-containing air passes through the filter, the dust is blocked in the fiber layer of the filter material. When the resistance of the fiber layer increases to the upper differential pressure value due to agglomeration of dust, the differential pressure switch will act and transmit the signal to the Ecolead Nanjing Yixio- intelligent PLC control system, start the motor, and automatically wind to replace the clean filter material to filter The ventilation system is maintained in a normal resistance state, so as to ensure the normal operation of the ventilation system.

The automatic mode adopts the automatic differential pressure control method: Ecolead intelligent PLC control box is connected to the differential pressure switch signal, the filter material exhaustion alarm signal, and the motor thermal overload protection signal interface

The principle is: when the difference between the pressure before and after the filter reaches the upper limit of the set value, the differential pressure sensor outputs a signal to control the rotation of the motor and start to replace the clean filter material. When the set rolling time is reached, the PLC outputs a signal to control the motor to stop working.

The control system is equipped with a material end alarm signal. The equipment is equipped with a limit plate. When the clean filter material is about to be used up, the limit plate touches the limit switch and sends out a signal to give an alarm at the end of the material to remind the staff to replace the filter material.

In manual control mode: an electric control cabinet is set on site, and filter material exhaustion alarm is set. The user can press the motor switch to replace the filter material at any time according to the site conditions.

The above is mainly a brief introduction to everyone about the control knowledge points of the automatic winding filter. I hope that the content mentioned above can help you.

Today we mainly discuss why clean sheds need to use anti-static materials as maintenance materials

Generally we all know that clean studio envelope materials include: anti-static curtain around (Anti-static PVC Curtain), ordinary strip curtain (PVC Strip) and (anti-static) acrylic plate (ACRYLIC).

Clean studio CLEAN BOOTH widely used in the electronics industry, which is mainly to prevent electrostatic discharge damage to electronic products (static-sensitive components)

This shows the harm of static electricity to the produced products, and secondly, whether the produced products need to be dust-proof.

The clean shed needs to be enclosed by an anti-static curtain:

1.       Anti-static grid curtain has ESD electrostatic discharge effect

2.       Play the role of isolating outdoor dust, etc.

Anti-static mesh curtain (ESD PVC CARBON PRINTED CURTAIN) is a blackconductive ink is printed on a good antistatic effect of transparent PVC film, the product will have better network surface ESD ESD effects

The resistance surface of the grid curtain surface is 10^4Ω-10^6Ω , and the resistance surface of the grid-free surface is 10^8Ω-10^10Ω

In addition, the black anti-static grid curtain has shading performance and can be used in clean rooms, clean workshops and other applications that require anti-static and shading.

The following is a brief introduction to the purpose of Nanjing Yixiou clean work shed. Customers know the actual use of clean sheds before they know whether their company needs clean sheds.

1. The purification level of the external workshop of the electronic workshop and other workshops is low, and the interior requires higher level requirements, such as assembly line work area, inspection table, special equipment work that releases dust particles or special odors. It is suitable for the construction of local small areas and the core The process is controlled in a clean area to increase the product yield. Especially some production equipment in the optoelectronic industry will release odors during the production process. The built-in fan filter system on the top of the Ecolead clean shed can further improve the internal air quality and provide employees with comfort Air environment.

2. The laboratory and scientific research unit are outside the general office and workshop area. The individual experimental research content needs to have a certain temperature, humidity, illuminance, and cleanliness requirements. The experimental work of specimens, bacteria, pharmaceutical ingredients, etc. is controlled in the clean room area to improve The success rate of scientific research projects.

3. In the fields of medicine and food, in the production and packaging process, it is generally recommended to use Nanjing Yixio’s 100-class clean shed. The higher the level, the safe and hygienic products produced can meet the national drug GMP and food QS standards. It can also achieve the trust of consumers. In the sales of clean sheds in recent years, more and more catering industries are gradually paying attention to food safety and hygiene control. Clean sheds, air showers and other equipment are widely used in fast food, cooked food, frozen food, bread baking and other enterprises.

This article is excerpted from Ecolead Nanjing Ecolead

Everyone knows that installing a primary filter plays a decisive role in the entire air-conditioning fan or aerodynamic equipment.

The primary filter can meet the following requirements:

1,   Effectively dispose of indoor air pollution, such as dust, etc., to provide cleaner air ;

2,   Effectively prevent the appearance of stains around the air outlet of the air conditioner, and extend the service life of the equipment ;

3.   The corresponding standard requirements are met in different levels of clean rooms. If the clean room wants to reach a certain level of cleanliness, it must be installed with a primary filter to effectively filter the air entering the room ;

4.   Deal with the appearance of serious dust accumulation in components such as fans, heat exchangers, pipes, etc., and also have the effect of removing peculiar smells.

However, in actual use, it is difficult for us to predict the service life of the primary filter, so we need to regularly test or check the resistance of the primary filter to avoid saturation and clogging of the filter element.

If the primary filter is not replaced in time, it will inevitably lead to a decrease in suction and a decrease in filtration accuracy.

If the primary filter is a common plate and frame filter, there are the following problems:

1)   Intermittent operation

2)   Labor intensive

3)   Low production efficiency

Therefore, for the above-mentioned working environment , the automatic winding air filter produced by our company (Nanjing Ecolead )

Has the following characteristics:

1. The workload of operation and maintenance is small – because the winding filter equipment is equipped with a filter material roll ( 15 meters long), if the equipment is 2 meters high, the filter material roll can be used 6-7 times. As long as the set pressure difference resistance is reached, the dirty filter material will roll down. No need for human monitoring and control.

2. The self-winding filter has a strong structure and can adapt to large negative pressure ventilation;

3. It can work continuously all year round to minimize the number of downtimes;

4. The transmission accessories of the automatic winding filter , the transmission motor and the intelligent PLC control are strictly required to operate in harsh environments. Therefore, the automatic winding filter of Nanjing Yixio definitely reduces the operating cost with stable quality;

It can be seen that the automatic winding filter is the most important basis for people to choose this equipment!

Paint spray booth paint fog solution–Nanjing Yixiou automatic winding filter

Generally speaking, the gas circulation and environmental protection emissions of paint spray booths have always been a concern. When painting , the air in the paint booth is mixed with paint dust, so the ventilation spray booth is especially critical. When the exhaust fan draws the air out through the filter cotton of the automatic winding filter, the paint dust will stick to the cotton (the filter cotton is usually installed at the suction and outlet of the exhaust fan)! Make the extracted gas cleaner! Filter cotton is for this purpose, it can filter small particles in the air. The filtration efficiency can reach 90-95%@0.5 µ m / 80%@0.5 µ m / 70%@1 µ m .

If the work of the spray booth is very busy, the drawn out paint dust can easily block the filter cotton. The use of an automatic roller shutter filter can effectively solve the problem of replacing the filter cotton. When the filter cotton reaches the set pressure difference value, the new filter cotton will be wound down to replace the dirty filter cotton that is saturated and filtered. No need for human monitoring and control of the wound filter material, no need to stop the machine

It can be seen that the winding filter with automatic function is the most important basis for selecting our company’s equipment for the gas filtration link of the exhaust emission system. The upstream is equipped with an air inlet flange, which is connected with the spray tower, and the downstream is connected with an activated carbon adsorption tower, forming a complete set of exhaust gas treatment system, so that the final exhaust gas can meet environmental protection standards.

The purification equipment products produced by our company, including air showers, transfer windows, workbenches, winding filters, etc., are all large in size, ranging from 1-2 square meters, and winding air filters are 5-6 square meters.

Transportation and can adapt to the requirements of climate change, moisture-proof, moisture-proof, shock-proof, rust-proof, and rough handling resistance. For any loss caused by poor packaging, or any rust damage caused by inadequate or improper protective measures , our company shall bear all costs and losses arising therefrom.

Our customers often confide that the pallets and cartons of other manufacturers’ air showers, transfer windows, or other purification equipment are intact when they are received, but when they are opened for installation, they found that some parts are slightly deformed or The paint drop phenomenon affects the appearance of the entire equipment. If you directly install and worry about the installation, you are worried about the appearance of the product. The owner refuses to accept the inspection, the return or repair has passed the statute of quality complaints, and the supplier cannot provide logistics. The company claims.

The packaging process of Nanjing Yixiou purification equipment :

1. When the equipment is produced and ready for loading, clean the inner and outer boxes first to prevent other pollutants and dust from adhering to the surface of the product.

2. Secondly, wrap the corners and corners of the box with kraft paper , which is easy to rub, which is suitable for long-distance cargo to reduce collisions.

3. The whole is wrapped with stretch film layer by layer , which can effectively reduce the rainy days of the freight , avoid the penetration of water, and prevent the entry of dust and liquids

4. Bind the purification equipment in a wooden box, and fix the key parts with limit wooden strips to prevent the goods from moving during long-distance transportation.

5. Use thickened plastic-steel packing straps to fix the box body and the bottom tray to prevent collision and dumping during transportation.

5. The air shower room is suitable for general transportation. It must not be placed sideways, impacted or collided during transportation, and it is best to keep it flat.

6. After the air shower arrives at the destination, open the box for inspection as soon as possible to see if the parts are damaged due to transportation. If damage is found, you should tell the logistics company or the delivery driver, and indicate the relevant on the delivery note. Happening.

7. The packaged air shower room should be stored in a well-ventilated warehouse with a relative humidity of no more than 85% . There should be no acidic, alkaline and other corrosive gases in the surrounding air.

Although the packaging and transportation of the air shower is a complicated process, if you choose a regular air shower company, you can ensure the safety of the air shower, winding air filter and other equipment.

China’s clean room clean equipment processing and manufacturing industry is developed, especially in Jiangsu, Zhejiang and Shanghai. The quality of air showers and clean sheds is uneven, and the price of products varies greatly.

With the continuous improvement of the requirements of coastal production operations and the continuous development of science and technology, the research and development and use of filter equipment have become wider and wider, which meets the various individual requirements of industrial production conditions. This article introduces you a kind of filtering equipment, called “salt mist automatic winding filter”. From the name point of view, the equipment for filtering salt fog is generally only used in coastal areas. The following describes the series of products in detail.

1. What is a salt spray automatic rolling air filter filter?

Salt fog filter is a kind of filtering equipment commonly used to protect oil field motors and ventilators. It is suitable for coastal areas or areas with more salt fog. The composition of the salt spray filter is mainly composed of three parts, namely a waterproofer, a high-efficiency filter and a cabinet. In order to withstand the erosion of rain and salt spray, the materials of these parts are generally stainless steel 304 or stainless steel with a higher nickel content. Material composition.

Second, the filtering principle of the salt mist automatic rolling filter

The salt mist filter is equipped with a ventilator. When the ventilator is powered on, the humid air containing salt mist will be sucked into the filter. There is a rainproof device in the filter. When the inhaled water mist air meets the rainproof device It will condense into water droplets, and then the water droplets will flow along the groove on the inner waterproof core of the salt mist filter to the bottom of the rainproof device, and finally flow out of the salt mist filter.

If there is rainwater, the salt mist filter has a labyrinth leaf filter element, which can perform multi-layer filtering to keep the rainwater out of the filter element.

Three, the installation precautions of the salt spray roller shutter air filter

1. The salt mist filter is generally installed at the air inlet of the motor to filter moisture, salt and dust in the air to protect the motor.

2. If the salt mist filter is used in the generator set, it will generally be installed at the rear air inlet hood of the generator, and it is a flat installation form with the air inlet hood. In addition, the method of on-site drilling is generally adopted. To ensure the accuracy of drilling bolt holes.

3. If the salt spray filter is used in a DC motor, it is generally installed at the air inlet of the cooling fan and installed on the flange surface with the air inlet. The same method of on-site drilling is generally used to ensure the accuracy of the bolt holes. . And after the salt mist filter is installed, in order to reduce the air inlet resistance and ensure that there is enough air inlet to cool the motor, the other filter layer materials originally installed at the air inlet should be removed.

4. In addition, in order to prevent air leakage and ensure air intake, the connection between the salt mist filter and the air inlet must be strictly sealed.

5. Regardless of the purpose, after the installation of the salt spray filter, support and reinforcement measures must be taken at the bottom to ensure the reliability and safety of the installation.

6. After installing the salt mist filter at the air inlet of the motor, pay attention to the changes in the air inlet volume and temperature changes of the motor. Once abnormal conditions occur, timely measures should be taken to reduce the air resistance and increase the cooling air volume.

The salt mist winding filter is an upgraded and improved product of the ordinary salt mist filter, which avoids the work intensity of frequent filter replacement in offshore operations. It can be automatically wound to the power of 7-8 and the filter material needs to be replaced manually, saving 7- 8 times the labor cost and filter material cost, although the initial equipment investment is slightly higher, but in terms of later maintenance and operation costs, it is quite simple and cheap.

The above has introduced the filtration principle and installation instructions of the salt mist automatic roller blind filter.

The increasingly severe air pollution problem has caused many companies to develop product production yields and gas and sewage up-to-standard discharge problems into a bottleneck until the emergence of air filters, which brings the hope of sustainable development for companies. The role of the filter in the enterprise is reflected in two points, one is to provide a good working environment for the production of the enterprise, and the other is to purify the waste water and waste gas discharged by the enterprise. The automatic rolling curtain air filter is so important to the enterprise, you must pay special attention to the selection when choosing, and the editor will compile and compile some suggestions for you.

Important reminder one for roller shutter air filter manufacturers: consider the characteristics of the materials to be filtered and choose different filter materials

The main filtering object of the filter is the material. When selecting the filtering equipment, the company must first analyze the material that needs to be filtered in its own production to determine the relevant characteristics of the material, such as the concentration of the suspension, the particle size distribution of solid particles, etc. And so on, this can ensure that the filtering equipment plays a filtering role in a targeted manner. For environments with larger particle sizes and higher concentrations, G3 is used, and G4’s primary chemical fiber filter cotton is sufficient. For environments with volatile or toxic gases, consider using activated carbon filter materials, and consider explosion-proof treatment for the overall equipment. For the paint mist purification system, it is considered to use the paint mist filter of the paint mist industry to match the two-pronged filter to achieve a better filtering effect.

Important reminder for roller shutter air filter manufacturers 2: Determining the processing capacity of automatic roller shutter filter equipment is the key to selecting the right size

Some companies may have a relatively large production scale, and the processing air volume of the filter is quite large, so the size of the corresponding winding filter will also be relatively large. Nowadays, some leading companies in the optoelectronics industry purchase dozens of coiled air filters from our company to form a whole surface of fresh air filter wall, which achieves the filtering effect systematically on a large area. At the same time, there are also a large number of automated control methods. This saves the cost of manpower replacement of the filter.

Important reminder three for filter manufacturers: Fully consider the production environment and choose different designs of automatic roller shutter air filters

The production environment of the enterprise has a great influence on the design and selection of filters. If the temperature of the filter material is too high, special treatment is required. The use of high-temperature filters and vacuum filtration equipment can hardly reach the standard filtration efficiency. It is recommended to use a pressurized filter at this time; if the material is highly toxic, it is necessary to ensure good sealing of the filter equipment to prevent leakage of toxic substances. The design method of the automatic roller shutter filter is also recommended to use Nanjing Yixiou Company Patented design, replace the filter material from the outside, avoid entering and exiting the ventilation system, and protect the life and production safety of personnel.

The above is the three tips of how to choose automatic roller shutter filter, which is provided by professional filter manufacturer Nanjing Yixiou. I hope to help you. Nanjing Ecolead has guaranteed product quality and perfect after-sales service. I believe it can help you. If you are interested, you can contact our staff.
