Problems solved by technology

[0003] However, in the current bag filter on the market, the filter bags in the box are all fixed, so that the surface of the side of the filter bag near the air inlet has more dust accumulation, while the surface of the side of the filter bag far away from the air inlet cannot. It has been effectively used, resulting in low dust collection efficiency, short service life of filter bags and frequent cleaning of filter bags

Embodiment 1

[0028] Such as Figure 1-3 As shown, a self-transformed bag filter includes a box 1 and a partition 2 arranged in the box 1, and the partition 2 separates the inside of the box 1 into a clean air chamber 3 and a dust filter room. 4. The clean air chamber 3 is located above the dust filter chamber 4, the clean air chamber 3 is provided with an air outlet 5, the dust filter chamber 4 is provided with an air inlet 6, and the bottom of the dust filter chamber 4 is provided with The ash hopper 7 also includes a power mechanism 8, a transmission mechanism 9 and several self-rotating filter bag assemblies 10;

[0029] The power mechanism 8 is arranged on the clean air chamber 3 , the self-rotating filter bag assembly 10 is arranged on the partition 2 , and the power mechanism 8 is connected with the self-rotating filter bag assembly 10 through a transmission mechanism 9 .

[0030] The self-rotating filter bag assembly 10 includes a filter bag 101, a filter bag skeleton 102, a rotati...

Embodiment 2

[0038] Such as figure 1 and 4 As shown, on the basis of Embodiment 1, a filter bag cleaning mechanism 11 is also included, which is used to shake off the excessive dust accumulated on the filter bag 101 into the ash hopper 7 .

[0039] The filter bag cleaning mechanism 11 includes an air bag 111, a pulse solenoid valve 112 and a blowing pipe 113. On the blowpipe 113, one end of the blowpipe 113 is connected with the air bag 111, and the other end of the blowpipe 113 stretches into the clean gas chamber 3, and the end of the blowpipe 113 stretched into the clean gas chamber 3 is provided with Several spray holes 12 are located above the filter bag 101 respectively.

[0040] One end of the blowing pipe 113 protruding into the clean air chamber 3 is U-shaped, and the rotating shafts 103 are respectively located in the middle of the U-shaped end of the blowing pipe 113 .

[0041] A self-transforming bag filter in this embodiment is provided with a filter bag dust removal mechan...

Embodiment 3

[0043] On the basis of Embodiment 2, the air inlet 6 is provided with a heating device 13 .

[0044] An inclined baffle 14 is also arranged inside the box 1 , and the baffle 14 is located at the air inlet 6 .

[0045] In the self-transforming bag filter of this embodiment, the air inlet 6 is provided with a heating device 13, which can heat the dusty gas entering the box body 1 and prevent the humid gas from adhering to the filter bag 101. , improve the filtering effect; the box 1 is also provided with an inclined baffle 14, the baffle 14 is located at the air inlet 6, which can effectively settle the dust with large particles and large specific gravity into the ash hopper 7.

Abstract

The invention discloses a self-rotation type bag type dust collector, which comprises a tank body and a clapboard arranged in the tank body. The clapboard divides the inner part of the tank body intoan air purification chamber and a dust filtration chamber; the air purification chamber is located above the dust filtration chamber; an air outlet is formed in the air purification chamber; an air inlet is formed in the dust filtration chamber; an ash bucket is arranged on the bottom part of the dust filtration chamber. The self-rotation type bag type dust collector further comprises a power mechanism, a transmission mechanism and a plurality of self-rotation type filter bag components, wherein the power mechanism is arranged on the air purification chamber; the self-rotation type filter bagcomponents are arranged on the clapboard; the power mechanism is connected with the self-rotation type filter bag components through the transmission mechanism. According to the self-rotation type bagtype dust collector provided by the invention, the power mechanism drives a filter bag to self-rotate at low speed, so that the filter bag can be utilized maximally, the nonuniformity of dust accumulated on the surface of the filter bag is avoided, the dust collection efficiency and the service life of the filter bag are improved, the times for deashing the filter bag is reduced, and meanwhile, the rotated filter bag can also throw way partial dust by depending on a centrifugal force.

Description

technical field [0001] The invention belongs to the technical field of dust collectors, and in particular relates to a self-transforming bag-type dust collector. Background technique [0002] Dust collector is a widely used dust removal equipment, including bag filter, pulse bag filter, electrostatic precipitator, wet dust collector and electric bag filter and other types. There are two main purposes of the dust collector: one is to remove dust in the air, improve the environment, and reduce pollution, so sometimes the dust collection equipment for this purpose is called dust removal equipment, such as the dust collection equipment used for factory exhaust emissions Another use is to filter and collect powdery products through dust collection equipment, such as the collection and extraction of finished cement by cement systems. [0003] However, in the current bag filter on the market, the filter bags in the box are all fixed, so that the surface of the side of the filter b...
