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.

With the improvement of people’s living standards, people’s requirements for the quality of life are getting higher and higher, but with the rapid economic development, air pollution has become the focus of people’s attention. People want green mountains and rivers, but they can’t hinder economic development. , So the automatic roller shutter filter came into being, let’s take a look at it together.

The roller blind filter is a new type of filter that has absorbed advanced technology at home and abroad and has been researched and developed for many years. Compared with the traditional filter, the design is novel and the structure is more reasonable. The pressure difference between the front and rear of the filter is converted into an electrical signal. Mainly the filter material can be replaced automatically, including CHF-Ⅰ-3 automatic winding air filter, ZJL-Ⅱ-4 automatic winding herringbone air filter, ARF-Ⅰ-2 automatic winding mini Various types of filters such as type air filters.

Roller curtain filter mainly includes the following parts, namely: upper filter box, lower box mechanism, column frame, grid and stopper groove, transmission mechanism, intelligent control system and filter material.

An automatic alarm is installed in the filter box. When the filter material reaches the limit, the limit plate can activate the alarm. The column frame can choose a variety of materials, including cold plate spray, aluminum alloy profiles and Stainless steel, in which the transmission mechanism can ensure that the filter runs in harsh environments. The intelligent control system can effectively save energy and manpower. It is mainly due to the pressure difference controller. The use resistance is set in advance, which is higher than the established resistance. When the motor starts to run, the new material is automatically replaced, which is suitable for the purification of various environments.

Roller shutter filters are mainly used in blower inlet filtration of sewage treatment plants, tunnel ventilation in coal industry, pre-filtration of gas turbine inlet systems in power plants, and environments with high dust content and frequent replacement of filter materials, although these places pollute the environment. Serious, but the development of these industries cannot be interrupted, so we started with the disposal of waste materials.

Nowadays, with the development of the times, the quality of life is gradually improving. In order to ensure the air quality in the rooms, most families use air filters. There are many types of air filters, including winding, folding, bag, and barrel types, and various forms play different roles. So, we mainly come to understand the roll-up air filter.
The automatic rolling-blind air filter adopts a metal structure design as a whole, which is very sturdy and durable, and is very suitable for domestic use. Because it is automatic, the replacement of the filter material is automatic, which can self-adjust the surrounding air quality system, which saves manpower and material resources, and plays a role of high efficiency and energy saving. Next, let’s explain in detail what are the advantages of the automatic winding filter.
First, from the perspective of intelligent automation, it can not only automatically replace the filter material, but also perform real-time detection and comparison analysis based on the surrounding air quality, and then conduct self-regulation to realize the prevention of harmful substances such as dust and particles in the air. Of filtering. This not only facilitates people’s daily life, but also helps to efficiently save energy and avoids a series of adverse effects caused by air quality problems.
Second, judging from the design concept of the automatic roll-up air filter, we can intuitively and obviously feel its convenience and efficiency. Its overall structure is forged with a metal structure, which is strong and reliable, very practical, and suitable for use in various other environments such as homes.
Third, the dust content is high, and it can work continuously for several hours with high efficiency. The effect is better than ordinary filters, and the operation effect has strong stability.
Fourth, the filter material in the filter also has a certain sense of design. The “V”-shaped design can increase the filtering area of the automatic winding filter, thereby greatly improving work efficiency and realizing convenient and efficient dust-proof filtering. .
The above is the analysis of several unique advantages of automatic winding filters from various aspects. I hope to provide some suggestions and help for friends who need to buy filters.

Technical Parameters

Nowadays, the air quality problem is getting more and more serious, so it is very necessary for many families to buy air filters. There are many types of air filters, roughly divided into winding type, folding type, flat type, bag type, etc. So, it can be said responsibly that the roller shutter air filter is a relatively high-end air filter, with a high sense of design, and also has an excellent filtering effect during operation.

It is worth mentioning that the quality of the current rolling curtain air filters on the market is uneven, and we really need to be carefully screened. So how do we choose high-quality wound air filters to prevent us from buying unqualified and ineffective filters?

Performance characteristics of coiled air filter

The internal basic operating system of the rolling air filter can be divided into two parts, the first is the filtration system, and the second is the purification system. The difference between the coiled air filter and other types of air filters is that it has a strict pressure difference control, which can control whether the filter material needs to be replaced, and better control the time to replace the filter material to ensure the best Filter results to avoid unnecessary waste of resources.

How to choose a high-quality roll-up air filter

1. To see whether the quality of the filter is good or not, the most important thing is to look at the work efficiency, because it can most clearly know the difference between good and bad quality. The higher the efficiency, it proves that the filter system is more complete and high-quality, and can solve the problem of air quality in all aspects.

2. In addition to looking at work efficiency is not enough, the impact of resistance also needs to be paid attention to. Resistance is a necessary cost investment for an air filter, and its role in it directly affects the filtering effect of the filter, so this is unavoidable. But we can choose a filter with a lower resistance, and in the total cost investment, a part of it can be reduced correspondingly. This is not only to save money, but more importantly, to save energy.

3. Pay attention to the dust content. Obviously, it can be seen that a filter with a large dust content has a large filtering area and a higher working efficiency, which can achieve high-quality and ideal effects.

From the above, we can know that when choosing a coiled air filter , we should choose an air filter with high efficiency, low resistance, and a large amount of dust, so that we can choose a high-quality air filter to achieve good air quality. Carry out the role of purification.
