Description

Technical Field

[0001] This utility model relates to the field of filter design technology, and in particular to a bag filter assembly. Background Technology

[0002] Air bag filters are a common type of air filtration equipment. The filter bags are made of fibrous materials with many tiny pores between the fibers. When dusty air passes through the filter bag, dust particles larger than the pore size are directly intercepted on the fiber surface and cannot pass through the filter, thus achieving preliminary filtration of large particulate pollutants in the air.

[0003] However, during operation, as usage time increases, a large amount of dust gradually accumulates on the surface of the filter bags, leading to increased air resistance and consequently affecting filtration efficiency and ventilation volume. Regular inspection, cleaning, or replacement of the filter bags is necessary, increasing labor and material costs. This is especially true in large ventilation systems where the number of filter bags is large, making replacement and maintenance more complex and costly.

[0004] Therefore, it is necessary to provide a bag filter assembly to solve the above-mentioned technical problems. Utility Model Content

The two cleaning members 52 can be connected to the inner surface of the filter bag 21 by relative movement, and the impurities on the surface of the filter bag 21 can be cleaned by rotation.

[0037] The filter bag 21 is connected to the upper and lower ends by a first connector 22, and the support member 31 is connected to the upper and lower ends by a second connector 32. The first connector 22 and the second connector 32 are used to connect to achieve the connection and fixation of the filter bag 21 and the support member 31.

[0038] Both the first connector 22 and the second connector 32 are annular and can be made of materials such as stainless steel, aluminum alloy and carbon steel, preferably stainless steel. By connecting the upper and lower first connectors 22 and the second connector 32, the filter bag 21 can be fixed inside the support 31.

The fixing member 43 is connected to the limiting block 41 to fix the first connector 22 and the second connector 32.

[0040] The surfaces of the upper and lower first connecting members 22 are each circumferentially arrayed with multiple limiting blocks 41, and the surfaces of the upper and lower second connecting members 32 are circumferentially provided with the same number of limiting grooves 42.

The sealing plate 51 is used for transmission to enable the cleaning component 52 to clean the filter bag 21 while sealing the bottom of the protective shell 11. The transmission component 53 is used for transmission, and the adjusting component 54 is used to adjust the distance between the two adjusting components 54.

[0042] There are two sealing plates 51 and two transmission components 53.

[0045] The working principle of the bag filter assembly provided by this utility model is as follows:

[0046] During installation, firstly, the limiting blocks 41 on the surfaces of the upper and lower first connecting members 22 of the filter bag 21 are inserted one by one into the limiting grooves 42 on the surfaces of the upper and lower second connecting members 32 of the support member 31. Then, the fixing member 43 inside the bottom second connecting member 32 is inserted into the limiting blocks 41 on the surface of the bottom first connecting member 22 under the action of elasticity, thereby connecting and fixing the bottom first connecting member 22 and the bottom second connecting member 32. Next, the support member 31 is inserted into the interior of the protective shell 11 from the top until the top second connecting member 32 is connected to the surface of the support plate 12. The bottom first connecting member 22 and the second connecting member 32 are then connected to the inner bottom surface of the protective shell 11. Under the action of elasticity of the fixing member 43 inside the support plate 12, they are connected through the second connecting member 32. The surface of component 32 is embedded inside the limiting block 41 on the surface of the top first connector 22, thereby connecting and fixing the top first connector 22 and the top second connector 32. The top second connector 32 is then connected and fixed to the surface of the support plate 12. After installation, when the filter bag 21 needs to be cleaned, first rotate the adjusting component 54, and the transmission component 53 will drive the sealing plate 51 and the cleaning component 52 on its top to move towards each other until the two cleaning components 52 are connected to the surface of the filter bag 21. Then, start the driving component 62 to drive the cleaning mechanism 5 to rotate through the rotating component 61. The two cleaning components 52 are connected to the surface of the filter bag 21 and rotate and revolve to clean the impurities on the surface of the filter bag 21. Then, pour in water and open the discharge component 7 to flush out the impurities through the discharge component 7.

The shock-absorbing component 81 is used to reduce the vibration of the support member 31, and the third connector 82 is used to connect with the support member 31 to realize the shock absorption of the support member 31 by the shock-absorbing component 81.

They can be spring shock absorbers, rubber shock absorbers, air shock absorbers, etc., and are preferably spring shock absorbers.

[0053] The working principle of the bag filter assembly provided by this utility model is as follows:

[0054] During operation, the third connector 82 is connected to the surface of the support 31. The support 31 vibrates when subjected to external force, and the vibration is transmitted to the damping component 81 through the third connector 82. The damping component 81 absorbs the vibration force on the surface of the support 31 and dampens it, thereby reducing the vibration on the surface of the support 31.
