Environmental pollution is becoming more and more serious. Dust has an impact on the human body, production and even the ecological environment. China and the world are paying attention to environmental issues. Not only people need to keep clean air, but also the operation of machines, the accuracy and service life of work. Affected by the dust in life, the roller blind filter plays a major role. The importance of the roller blind filter is self-evident. Let us learn the production process of the roller blind filter together.

First, blending

Mainly according to the different requirements of customers, different types of fiber cotton are weighed in different proportions and then added to the mixer for mixing to obtain a uniformly mixed fiber cotton;

Second, open

Use special equipment to make the mixed fiber cotton into fibers with uniformly stretched tows. This process mainly uses a licker roller device to forcefully open the fiber cotton, which is carried out twice, and finally the fan is sent to the mixing box for further mixing. This process is mainly to turn the fiber cotton block into a cotton bundle. ；

Third, combing and laying the net

This is an important step for the orderly arrangement of fiber cotton, which completes the problem of orientation. After the fiber cotton is made into a uniformly distributed cotton layer, it is delivered to the upper screen, and then laid into a net, completed by shaking the screen back and forth, and finally sent to the oven for the next step.

Fourth, finalize

The hot air is applied first, and then the cold air is applied. The former uses low-melting fiber to melt and bond various fibers together to form a mixed fiber cotton, and the latter is mainly used for cold air shaping;

Fifth, curl

This is the last step in the production of fiber cotton, and of course it cannot be ignored. It is mainly cut according to actual needs and then rolled into rolls for use by manufacturers.

The above is the production process of roller blind filter cotton . Although it seems simple and easy to implement, each step of the production of a good roll of filter cotton cannot be underestimated. Only by treating each step seriously can the quality be produced. The filter cotton can hold up a piece of clean air for people.

Performance parameters:

With the development of science and technology in China, the development of economy and industry will follow. Therefore, some factories will adopt more advanced equipment. In this equipment, the instruments are relatively sophisticated and are easily affected by dust. Normal factories will use automatic rolling curtain air filters to filter the air, so for such a set of advanced equipment, where is it used?

First, the metal smelting industry

The most heavy-duty enterprise in China is the metal smelting industry. The air quality requirements in the workshops of such enterprises are relatively high. The overall air quality is very poor, the particulate pollutants are serious, and the area is large, and it is difficult to control and control. Therefore, automatic rolling curtain air filters are used to clean the sintering system, ventilation system and other links.

Second, the power plant

Used in power plants, gas turbines used in power plants need to ensure a high degree of cleanliness, so general power plants will use automatic winding air filters to purify and filter the air inlet system of the complete set of equipment.

Third, on the highway

This type of equipment is also used on highways, mainly in culverts. Because the air circulation in the culverts is poor, the cleanliness of the air must be ensured when air conditioning is performed, so this type of equipment must be used. The air filter filters the air.

Fourth, subway and civil air defense projects

It is used in subways and civil air defense projects because artificial ventilation is necessary in these two facilities. Therefore, automatic rolling curtain air filters are used to filter the inhaled air, so as to ensure the cleanliness of the air in these projects. . Prevent bad air from adversely affecting the human body.

Fifth, the coal industry

There are a lot of dust particles in this industry, many people engaged in this labor project have occupational diseases, and the entire respiratory tract and lungs have detailed injuries. In order to ensure fresh air in the respiratory tract of people working underground, this air filter must be used at the vent to filter the air. This is an automatic replacement air filter device adapted to the harsh environment.

The above is a list of some places where automatic rolling air filters are often used. There are still many environments where you can see the sound and shadow of the winding filter. I will not list them one by one. I hope it can be used as a reference for customers.

The listing of roller shutter filters undoubtedly brings good news to the environment for enterprises, not only solving the time-consuming and labor-intensive work problems in enterprise work, but also solving a major problem of environmental pollution, bringing people green hills and greens. Water, compared with the traditional filter, in which aspects are it different? This should also be the issue that everyone is most concerned about. Let us take a look today.

First, compared with traditional filters, a roll of filter material is mailed in the upper box of the roller blind filter, which avoids the frequent disassembly, cleaning and installation of traditional filters, saves manpower, and does not need to stop during cleaning. The machine greatly improves the work efficiency. Of course, on the basis of not affecting the work efficiency and service life, under normal circumstances, the filter material can be replaced for half a year or even longer.

Second, because there is no need for frequent disassembly, washing and installation, it greatly reduces the cost of later operation and maintenance, and at the same time can reduce the use of some staff. For those companies that are currently in short supply but have high requirements for use, winding filters It is undoubtedly the best choice, saving manpower and financial resources.

Third, most of the winding filters use fully automated design, simple operation and easy to control. Due to the existence of the central control system, most of the operations can not be implemented at the first site, and there is no need for staff to frequently go to the site for maintenance. , Which greatly improves the efficiency of work.

Fourth, due to the reason that it does not need to be disassembled frequently, the roller shutter filter is particularly suitable for applications in environments with particularly high dust content. Of course, it is suitable for various occasions.

Although the initial investment of the roller shutter filter is relatively large, its design is flexible, and the size can be designed according to the user’s own needs. At the same time, its structure is simple, easy to install, and high safety performance. Perhaps this is the roller shutter type. Filters can stand out among the many filters. Although there are disadvantages, the advantages cannot be ignored.

Technical Parameters

The automatic rolling curtain filter is a new type of air filtration equipment specially for air purification. After long-term research and development, it has made a major breakthrough in automatic function on the basis of traditional filters. It uses the pressure difference conversion before and after the filter as the basis for the sensor to receive the signal, and automatically replaces the filter material, which is the best choice for dust removal. So what is it made of that gives it such a powerful function? Let me do an in-depth analysis of its structure, so that users have a more intuitive understanding.

1. New filter box

The new filter box is to store clean rolling filter media. There is a limit plate on the new filter box. When the filter material is used up, an alarm will sound and the friction of the filter material roll will be increased to prevent the filter material from automatically sliding down.

Second, the old filter box

The lower box is the place where the filter material is crimped. Inside it is provided with a feeding wheel shaft, a rotating shaft, a sprocket, a coupling and a pressing plate for tightening the filter material.

Three, the baffle plate

When the automatic roller blind filter is working, the filter material and the air intake direction must be on a vertical plane. Because the steel plate has good rigidity, it is not easy to bend and deform. Therefore, slats must be used for support. At this time, the barrier fence plays a supporting role.

Fourth, the pressure plate

When the work stops, the return air can easily blow back the filter material to make it shift. Therefore, it is necessary to adjust the positioning bolts on the pressing plate according to the thickness of the filter material. And it can also increase the friction of the filter material to avoid the filter material chute.

Five, transmission mechanism

The main components of the transmission mechanism are the motor and the reducer. The main difference lies in the difference in the filter period due to the amount of dust. The transmission process can be operated manually and automatically. The control circuit consists of a switch, a contactor, a time relay, and a pneumatic micro-pressure sensor, etc. It can use a power supply of 380V or 220V, 50Hz. When the filter resistance value exceeds the set value, the motor stops and the refueling process ends. When the filter material is exhausted, the switch on the top of the material reel will be opened immediately, the motor will stop running, and at the same time, it will form a closed loop with the buzzer and alarm indicator to send out an alarm. After the filter material is sufficient, the automatic control system returns to its normal state.

How about it, do you have a general understanding of the automatic rolling filter? I believe it will play a very important role in our procurement selection.
