When it is necessary to change the filtration diameter, the motor is started to rotate the position of the rotating block. At the same time, the rotating block drives the movable pipe and the sealing rubber block to rotate simultaneously. It stops rotating under the filter cloth bag with a different filtration diameter. After the dust-containing gas enters from the bottom of the filter cloth bag, the gas will penetrate to the outside through the inner wall of the outer cloth bag, filtering the dust on the inner wall of the outer cloth bag. The gas will also enter the inside of the inner cloth bag through the pipe wall of the inner cloth bag and flow out of the air outlet through the conical ring, while the dust is filtered on the outer wall of the inner cloth bag, achieving the effect of different-diameter filtration.

[0021] Please refer to Figure 1 - Figure 2 , a dust removal device for a feed factory, including a box body 1. The bottom of the box body 1 is evenly and fixedly installed with support feet 11 in a circular ring shape for fixing and supporting the box body 1. The middle of the bottom of the box body 1 is provided with a discharge port 12 for discharging dust and impurities, which is convenient for unified collection. The middle of the inner wall of the box body 1 is fixedly installed with a positioning plate 13. The bottom of the positioning plate 13 is fixedly installed with a narrow plate 131. The positioning plate 13 is provided with a chute in the middle of the narrow plate 131. The inner part of the positioning plate 13 is evenly and circularly penetrated with circular grooves. The bottom diameter of the circular grooves in the positioning plate 13 is large. The inner wall of the box body 1 is fixedly installed with a ventilation plate 14 below the top wall. The ventilation plate 14 is made of a breathable material as a whole. The inner part of the ventilation plate 14 is provided with the same circular grooves as the positioning plate 13. The end with a large diameter of the circular grooves in the ventilation plate 14 is located at the top of the ventilation plate 14. One side of the box body 1 is fixedly installed with an air outlet 15 between the top wall of the box body 1 and the ventilation plate 14. Connecting the air outlet 15 to an external fan can suck out the clean and impurity-free air inside the box body 1.

[0022] Please refer to Figure 1 - Figure 2, on the other side of the box body 1, an air storage tank 2 is fixedly installed. Inside the air storage tank 2, there is a compressed air storage bag. On the top of the air storage tank 2, there is a pulse device 3. Above the air storage tank 2 on the inner wall of the box body 1, a special-shaped groove is opened. The special-shaped groove has a small diameter in the middle and large diameters at both ends, which is used to fix the position of the pipeline. Inside the special-shaped groove, an air delivery pipeline 4 is fixedly sleeved. One end of the air delivery pipeline 4 inside the box body 1 is fixedly connected to an annular pipeline 5. At the bottom of the annular pipeline 5 at the circular groove, an air diffuser 51 is fixedly installed.

Between the pulse device 3 and the electromagnetic valve 6, a magnetic valve pipeline is fixedly connected. Inside the end of the magnetic valve pipeline connected to the pulse device 3, there is a pulse valve.

[0023] Please refer to Figure 1 - Figure 3 , inside the circular grooves of the positioning plate 13 and the air permeable plate 14, six filter cloth bags 7 are fixedly installed. The number of filter cloth bags 7 is six, and two filter cloth bags 7 are in a group. The filter holes of each group are of different sizes, which are used to filter dust particles of different diameters. The filter cloth bag 7 includes an outer cloth bag 71. Both ends of the outer cloth bag 71 are open. At both ends of the outer cloth bag 71, there are fixing rings, which are adapted to the large diameter of the circular groove. Inside the outer cloth bag 71, there is an inner cloth bag 72. Between the outer ring of the top opening of the inner cloth bag 72 and the inner wall of the outer cloth bag 71, a conical ring 721 is fixedly connected. The bottom of the inner cloth bag 72 is conical. When the dust-containing gas enters from the bottom of the filter cloth bag 7, the gas will penetrate outwards through the inner wall of the outer cloth bag 71, filtering the dust on the inner wall of the outer cloth bag 71. The gas will also enter the inside of the inner cloth bag 72 through the pipe wall of the inner cloth bag 72 and flow out through the air outlet 15 after passing through the conical ring 721, while the dust is filtered on the outer wall of the inner cloth bag 72, thus achieving the effects of fine filtration and fast filtration speed.

[0024] Please refer to Figure 1 - Figure 4 , at the bottom of the positioning plate 13, a position-changing device 8 is fixedly installed. The position-changing device 8 includes a functional block 81, a rotating block 82, and a top block 83. The top of the functional block 81 is movably connected to the rotating block 82. The top of the rotating block 82 is movably connected to the top block 83. The top end of the top block 83 is fixed below the positioning plate 13. Between the position-changing device 8 and the inner wall of the box body 1, there are fixing columns for fixing the position of the position-changing device 8. Inside the functional block 81, there is a delivery pump 811. At the upper and lower ends of the delivery pump 811 inside the functional block 81, there are pipeline openings. Inside the rotating block 82, movable pipelines 822 are symmetrically arranged. At the end of the movable pipeline 822, there is a sealing rubber block 823. The sealing rubber block 823 is adapted to the sliding groove. At the top of the sealing rubber block 823, there is an opening adapted to the outer cloth bag 71. One end of the movable pipeline 822 is rotatably sleeved in the pipeline opening at the top of the functional block 81. At the top of the rotating block 82, there is a driving groove inside the top block 83. Inside the top block 83, a motor 831 is fixedly installed. The output shaft of the motor 831 meshes with the driving groove. Inside the pipeline opening at the bottom of the functional block 81 at the middle of the discharge port 12, a filter pipeline 84 is fixedly installed.

[0025] Working principle: Place the whole device in a feed mill. Use an external fan to convey the dust-containing air generated during feed production into the interior of the filter pipeline 84. Connect the air outlet 15 to a blower. The transfer pump 811 pumps the dust-containing air inside the filter pipeline 84 into the movable pipeline 822. The top of the sealing rubber block 823 is adapted to the bottom of the filter bag 7. The dust-containing air enters the interior of the filter bag 7 through the connection between the sealing rubber block 823 and the filter bag 7. When the dust-containing gas enters from the bottom of the filter bag 7, the gas will penetrate outward through the inner wall of the outer bag 71, filtering the dust on the inner wall of the outer bag 71. The gas will also enter the interior of the inner bag 72 through the pipe wall of the inner bag 72 and flow out through the air outlet 15 after passing through the conical ring 721, while the dust is filtered on the outer wall of the inner bag 72. The clean air without dust after filtration passes through the air-permeable plate 14 and is sucked out of the box body 1 by the blower connected to the air outlet 15 through the conical ring 721. When too much dust is adsorbed on the inner wall of the outer bag 71 and the inner wall of the inner bag 72, stop the transfer pump 811 from conveying the dust-containing air, and start the motor 831 to rotate the position of the rotating block 82, causing a dislocation below the filter bag 7, which will not affect the falling of the dust. Start the pulse valve and the solenoid valve 6, and pump the compressed air inside the air storage tank 2 into the interior of the filter bag 7 from the conical ring 721, so that the outer bag 71 and the inner bag 72 are filled with compressed air and expand rapidly, thus vibrating rapidly. The dust falls down through the vibration, passes through the slope of the transposition device 8, and finally flows out of the interior of the box body 1 through the discharge port 12;

[0026] When it is necessary to change the filtering diameter, start the motor 831 to rotate the position of the rotating block 82. At the same time, the rotating block 82 drives the movable pipeline 822 and the sealing rubber block 823 to rotate simultaneously, and stop rotating below the filter bag 7 with different filtering diameters. Filter the dust-containing air according to the above operations.
