1、 Equipment structure description and main technical parameters

1.1 Equipment description and working principleAnd structural description

Equipment Description:

The main material of the framework is composed of self-designed aluminum alloy profiles and stainless steel square tubes; The material box is composed of sheet metal painted parts.

The overall structure is made of metal, which is sturdy and reliable, and can meet the harshest working environment.

The rolling shutter filter adopts precision transmission control such as sprocket and gear reduction mechanism (PLC, relay automatic optional),

Realize precise control of roller shutter filter materials and improve the utilization efficiency of filter materials.

◇ Configurable differential pressure gauge (differential pressure sensing switch), timely reminder to replace new filter material.

The equipment is equipped with a manual drive handwheel and a matching deceleration mechanism. When the unit is running with high wind resistance,

Through the transmission of the deceleration mechanism, operators can still easily achieve the goal of replacing the filter material.

Modular assembly can meet the requirements of larger air volume, effectively save energy, reduce manpower, and run more economically.

working principle:

The new filter material is installed in the feeding box. When the air inlet with high concentration of dust passes through the rolling filter, the pressure difference before and after the filter gradually increases with the increase of dust particles.

When the resistance of the filter rises to the final resistance value, maintenance personnel enter the fresh air chamber for replacement operation.

◇ Optional maintenance and repair system, including inlet chamber maintenance track, track replacement car, etc.

The handwheel drives the reduction mechanism through rotation, and the reduction mechanism drives the spool in the feeding box to rotate through the transmission sprocket system, thereby rolling the dirty filter material onto the lower filter material shaft and replacing it with clean filter material on the filtering section.

The operating length of the filter material is visually monitored by on-site personnel, and when all the dirty filter material is recovered from the filter section to the discharge box.

Filter material replacement completed.

The rolling shutter air filter uses specialized synthetic fiber filter materials, and the fiber structure from the windward side to the exhaust side is from sparse to dense, thus achieving deep filtration and low resistance. It has the characteristics of excellent ventilation and dust removal ability, low resistance, high strength, stable performance, and is non-toxic, odorless, non-volatile, and easy to replace.

◇ Maximum operating wind speed of the equipment:≤3m/s

◇ Initial resistance:≤60Pa

◇ Final Resistance: The Power of Ancestors2~2.5times

◇ Transmission mode: manual/automatic

◇ Power Supply:--/380V

◇ Environmental air temperature:-20°Cto40°C

◇ Relative humidity of the environment:<90%RH

When designing or selecting a rolling shutter filter based on air volume, it is generally not recommended to overload the filter for a long time beyond the design air volume. Otherwise, the filter cotton is prone to clogging, the service life is shortened, the pressure loss increases, the filtering effect is reduced, and in some cases, the overall frame may deform severely. We usually recommend a design wind speed of2.5m/s, At appropriate wind speeds, filter cotton has the best interception effect on particulate matter. High filtration speed can cause excessive pressure loss, and flying particles cannot be effectively intercepted, reducing the interception effect and making the roller shutter filter cotton prone to clogging. G4 efficiency when used at a wind speed of 2.5m/sThe initial resistance of the roller shutter filter cotton is about40PA， The design value of the differential pressure switch within the numerical range of 30-300PA is 100PA.

2、 Features of roller shutter filter

2.1 Intelligent Filter Material Replacement System

By monitoring the pressure difference in the area, it is possible to determine whether the filter material needs to be replaced, ensuring maximum efficiency of the filter operation. It can be installed once and only needs to be replaced for long-term use, greatly reducing the cost of use.

2.2 Manual speed regulation and deceleration device

On the inlet side of the filter material, a speed control and deceleration system connected to the replacement handwheel is installed. When the air conditioning unit is working, replacing the filter cotton greatly reduces the strength of manually overcoming the rolling resistance to rotate the roller shutter. It can easily replace the filter cotton during operation and reduce the waste caused by the shutdown maintenance of the entire air conditioning unit.

2.3 High quality filter screen

The main raw material of the filter material is synthetic fiber, and the fiber structure from the windward side to the windward side is from sparse to dense, thus achieving deep filtration and obtaining low resistance. It has the characteristics of excellent ventilation and dust removal ability, low resistance, high strength, stable performance, and is non-toxic, odorless, non-volatile, and easy to replace. The two sides of the filter material are designed with edge wrapping to minimize air leakage on both sides of the filter material.

2.4 Filter material quick change shaft structure

When dismantling the filter material in the collection box, simply unscrew the fixing parts of the collection box, open the movable cover of the collection box, and easily remove the dirty filter material. The operation method for replacing the filter material in the discharge box is the same as above.

2.5 Durable and sturdy frame structure

This set of equipment is entirely made of metal structure, treated with spray coating, beautiful and sturdy, and can be used in slightly corrosive and humid environments.

2.6 Seamless splicing of multiple modules

Modular assembly, with specially designed fastening rods connecting modules and frames usingEVA strip sealing, easy to assemble, especially suitable for large-area work environments.

3、 Main application industries

Sewage treatment, steel metallurgy, mining, chemical industry, gas production, and high air volume air conditioning supply systems, and long-term use as supporting equipment for blower manufacturers. To meet the different air volume requirements of users, the filtration unit can be used separately or multiple units can be combined in parallel to form a row of filtration units. It can also be designed and manufactured according to user needs and actual working conditions on site.
