Description

Technical Field

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

[0002] A baghouse dust collector is a dry dust filtration device. It is suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When the dust-laden gas enters the baghouse dust collector, larger, heavier dust particles settle down due to gravity and fall into the dust hopper. The gas containing finer dust particles is purified as it passes through the filter bags, where the dust is trapped.

[0003] During dust filtration, some foreign objects will be mixed in with the gas and enter the device. The foreign objects are of uneven size, and some larger foreign objects will accumulate in the device, causing blockage and affecting the normal discharge of dust. The devices on the market are not equipped with a crushing function, so they cannot crush the larger foreign objects and agglomerated dust, thus failing to solve the problem of easy blockage. Optimization is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bag filter with a crushing function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Detailed Implementation

[0023] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] Example 1

[0026] A bag filter with a crushing function, such as Figure 1-4 As shown, the dust removal system includes a dust collection box 1. A dust hopper 11 is installed at the bottom of the dust collection box 1, and the dust hopper 11 is adapted to the dust collection box 1. An installation plate 16 is installed on the inner wall of the dust collection box 1. The installation plate 16 has multiple sets of filter holes. Filter bags 17 are installed through the filter holes and are adapted to the filter holes. An air inlet pipe 13 is connected to one side of the dust collection box 1 and is connected to the lower end of the dust collection box 1. An exhaust pipe 5 is connected to the other side of the dust collection box 1 and is connected to the upper end of the dust collection box 1. A crushing component for crushing foreign objects and agglomerated dust is provided on one side of the dust hopper 11, and a cleaning component for cleaning the filter bags 17 is provided on one side of the dust collection box 1.

[0027] In use, the gas containing dust is fed into the dust collector box 1 through the inlet pipe 13 connected to the conveying pipe. After being fed in, the larger dust particles and foreign objects mixed in fall into the ash hopper 11 for discharge due to gravity. The smaller dust particles enter the filter bag 17 along with the gas and are filtered by the filter bag 17. After the gas is filtered and purified by the filter bag 17, it is discharged through the exhaust pipe 5 connected to the pipe. The smaller particles are blocked in the filter bag 17 to prevent them from being discharged together with the gas.

[0028] The crushing assembly includes a rotary motor 15. Two sets of rotary motors 15 are provided and are respectively fixed to the outer wall of one side of the ash hopper 11 by bolts. A rotating shaft 10 is connected to one side of the rotary motor 15. One end of the rotating shaft 10 is rotatably inserted through the ash hopper 11. A crushing blade 14 is installed at one end of the rotating shaft 10. Multiple sets of crushing blades 14 are provided and are arranged sequentially on the rotating shaft 10.

[0029] In use, the rotation of the rotating shaft 10 and the crushing blade 14 can be controlled by the two sets of rotating motors 15 rotating forward and reverse respectively. After dust and foreign objects fall into the ash hopper 11, they can be crushed by the rotating crushing blade 14, thereby avoiding blockage.

[0030] The cleaning assembly includes a fan 2, which is fixed to the top outer wall of the dust collection box 1 by bolts. A suction pipe 3 is connected to one side of the fan 2. An air conveyor frame 18 is fixed to the top inner wall of the dust collection box 1. The air conveyor frame 18 is connected to the filter bag 17. The fan 2 is connected to the air conveyor frame 18.

[0031] When in use, the fan 2 is started and air is drawn in through the suction pipe 3. The air is then fed into the filter bag 17 through the air conveyor frame 18, thereby cleaning the inside of the filter bag 17. The dust attached to the inside of the filter bag 17 can be blown off to avoid affecting the filtration effect. The blown-off dust falls into the dust hopper 11 and is discharged.

[0034] To limit the location of the device, such as Figure 2 , 4 As shown, a limit frame 8 is installed at the bottom of the support leg 7, and the limit frame 8 has multiple sets of screw holes;

[0035] When in use, simply align the bolt holes of the limit bracket 8 with the bolts at the fixing points, put the bracket in, and tighten the nut to fix the device. This will limit the device and prevent unnecessary displacement.

[0036] To make the fixation more secure, such as Figure 2 , 3 As shown in Figure 4, a pad 9 is provided at the bottom of the limiting frame 8, and the pad 9 is made of rubber.

[0037] When in use, the gaps at the fixing point can be filled by the rubber gasket 9, which makes the fixing more secure and prevents shaking after fixing;

[0038] To prevent foreign objects from being sucked into fan 2, such as Figure 1 , 2 As shown, a filter screen 4 is detachably installed at one end of the suction pipe 3;

[0039] During use, the filter screen 4 filters the air drawn in through the suction pipe 3, thus preventing foreign objects from being sucked into the fan 2 and causing jamming that would affect its operation.
