As we all know, the air contains a lot of dust, which is generally harmless to the human body. However, with the development of industry and changes in the ecological environment, the dust in the air has exceeded the range of people’s tolerance. They have been working and living in such an environment for a long time. , It is a great threat to human health, so various filters have been produced. Among them , the roller curtain air filter is widely used with its unique advantages. It is mainly responsible for removing particulate impurities in the air. Let us take a look at its specific advantages.

1. Large filtration area

There are many specifications of the roller shutter air filter , but the most important point is that the filter area is large, which is suitable for the environment that requires a large area and large-scale treatment of harmful particles in the air, and the effect of a single filter is better than that of ordinary filters. .

2. Low operating cost

Most of the roller blind filter adopts automatic control system, and at the same time, it can precisely control the winding length of the filter material, which can save the filter material, and the price of the filter material itself is not high;

3. Long service life

This is mainly from the perspective of filter material replacement. A roll of filter material can be used multiple times for a long time without the need to shut down and replace each time. At the same time, the frame around the filter material can be used permanently;

4. Simple maintenance

On the one hand, the filter material does not need to be disassembled and cleaned frequently, and there is no need to manually replace the filter material on a new side, which greatly saves manpower. The staff needs to pay attention to it at any time in the central control room.

The rolling curtain air filter has simple structure, convenient production and processing, and easy installation. For the user, it is simple to operate and hassle-free maintenance. It is a good air filter and is suitable for various places, especially for large air volumes. Purification of low wind pressure environment.

Roller curtain air filter has its indispensable position. We know that many industrial production must be carried out in a relatively clean space, such as pharmaceutical factories, precision electronics, and other environments. There should be no dust in these environments, so air filters are needed. , To ensure that the air in the environment is clean.

Rolling curtain air filter is a kind of filter with very good sales for the company. Many factories will adopt such a set of filtering equipment. Therefore, many people have seen such equipment, but maybe not many people know it The working principle of, today I will popularize the knowledge for everyone, let you know what is the working principle of the roller shutter filter?

For this set of equipment, the main filtering function is the upper filter material . There is a loading box in the roll-up filter . When the air blown in from the air conditioner enters the filter, the dust in it will be affected. Stay in the filter, but with the extension of working time, the dust content in the filter material will increase, in this case the pressure difference between the front and rear of the filter will also change.

As the pressure difference increases, the resistance of the filter will increase, and when this value reaches the originally set range, the pressure difference switch will be activated. After the switch is activated, the motor will be connected to the power supply, which is the whole device will start to work.

Then the filter material is driven to rotate through the roller blind device, so that the new filter material can replace the used filter material, and the motor will be turned off again after this work is completed.

The control of the entire system is controlled by a photoelectric system. In this case, it can ensure that the filter material is replaced more accurately, and only the filter material can be completely replaced without wasting new filter material.

Since the control of this equipment is automated, you only need to manually input and save the data when using the equipment, and there is no need to manually operate during the work process, so many factories are happy to use such equipment In order to save labor costs, and also because the control of the machine is always more precise than the control of the human.

This is the working principle of the roller blind filter . Because of its working principle, the whole equipment has a very good effect when working. It not only has the powerful function of filtering air, but also is very convenient to control.

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.
