[0002] A bag filter is a dry dust filtering device. It is suitable for collecting fine, dry, and non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt. The dust-containing gas is filtered by the filtering action of the fiber fabric. When the dust-containing gas enters the bag filter, dust with large particles and high specific gravity settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, and the gas is purified. It has been widely used in the fields of flue gas treatment, dust filtration, and environmental protection.

[0003] In the use of existing bag filters, it is found that manual clogging cleaning of the filter bags is labor-consuming.

A transmission box body 3 is installed at the bottom of the dust collector body 2. A supporting bottom column 4 is fixedly installed at the center of the transmission box body 3. The positioning ring 1 is rotatably installed around the supporting bottom column 4. A rotating transmission assembly 5 is installed inside the transmission box body 3, and the rotating transmission assembly 5 is in transmission cooperation with the positioning ring 1

[0053] This application is used to remove clogs from the dust removal bags of a bag - type dust collector to prevent the dust removal bags from being clogged and affecting the dust removal efficiency. First, the transmission box body 3 is fixedly installed at the bottom of the dust collector body 2, and then the positioning ring 1 is rotatably installed on the transmission box body 3 and is sleeved outside the supporting bottom column 4. The top surface of the positioning ring 1 and the top surface of the supporting bottom column 4 are at the same height, and the outer ring of the positioning ring 1 extends to the side wall of the dust collector body 2. The positioning ring 1 and the supporting bottom column 4 form a flat surface at the bottom. The rotating transmission assembly 5 on the transmission box body 3 drives the positioning ring 1 to rotate

[0054] A cloth bag end positioning block 6 is fixedly installed on the supporting bottom column 4. A top partition 7 is also installed inside the dust collector body 2. A cloth bag end positioning and conveying pipe 8 is fixedly installed below the top partition 7. A shrink - mouth dust removal cloth bag 9 is movably sleeved between the cloth bag end positioning block 6 and the cloth bag end positioning and conveying pipe 8. A cloth bag cleaning mechanism is fixedly installed on the positioning ring 1, and the cloth bag cleaning mechanism is in movable cleaning cooperation with the shrink - mouth dust removal cloth bag 9

[0055] The cloth bag end positioning block 6 on the supporting bottom column 4 and the cloth bag end positioning and conveying pipe 8 below the top partition 7 are used to fix the shrink - mouth dust removal cloth bag 9. The shrink - mouth dust removal cloth bag 9 is fixed by tying the drawstring knots after shrinking at both ends at the positions of the cloth bag end positioning block and the cloth bag end positioning and conveying pipe 8. The cloth bag cleaning mechanism on the positioning ring 1 can rotate around the shrink - mouth dust removal cloth bag 9 for repeated rotational knocking to remove clogs, preventing the shrink - mouth dust removal cloth bag 9 from being clogged and affecting the dust removal efficiency

[0056] The cloth bag cleaning mechanism includes a vertical positioning plate 10 fixedly installed on the positioning ring 1. An L-shaped positioning plate 11 is installed on the side wall of the vertical positioning plate 10. A number of clog clearing rods 12 are movably penetrated through the L-shaped positioning plate 11. One ends of the number of clog clearing rods 12 are movably attached to the necked dust removal cloth bag 9, and the other ends are commonly installed on a force transmission plate 13. A return spring 14 is installed between the force transmission plate 13 and the L-shaped positioning plate 11 outside each clog clearing rod 12. A bearing platform 15 is fixedly installed on the top of the vertical positioning plate 10. A cleaning driving assembly 16 is installed on the bearing platform 15. The cleaning driving assembly 16 is fixedly connected to the force transmission plate 13.

[0057] The cloth bag cleaning mechanism drives the vertical positioning plate 10 to rotate through the rotation of the positioning ring 1. The vertical positioning plate 10 drives the L-shaped force transmission plate 13 to rotate. A number of clog clearing rods 12 on the L-shaped force transmission plate 13 then rotate in a fitting manner around the necked dust removal cloth bag 9. At the same time, by moving the force transmission plate 13, the clog clearing rods 12 can be driven to repeatedly strike the necked dust removal cloth bag 9 to clear the blockage of the necked dust removal cloth bag 9 and shake off the blocked dust. The return spring 14 is used to increase the vibration force of the clog clearing rods 12. The cleaning driving assembly 16 installed on the bearing platform 15 drives the force transmission plate 13, so that the force transmission plate 13 drives the clog clearing rods 12 to repeatedly strike the necked dust removal cloth bag 9.

[0059] The cleaning driving assembly 16 drives the elliptical collision block 18 to rotate through the output rotation of the first driving motor 17. A speed reducer is installed in cooperation with the first driving motor 17. When the large-diameter end of the elliptical collision block 18 strikes and fits with the force transmission collision plate 20, it will drive the force transmission collision plate 20 to move to the side away from the vertical positioning plate 10. Then, through the C-shaped force transmission rod 19, the force transmission plate 13 is driven to move to the side away from the vertical positioning plate 10. At this time, the clog clearing rods 12 also move to the side away from the necked dust removal cloth bag 9, and at the same time, the return spring 14 is compressed to store energy. When the large-diameter end of the elliptical collision block 18 continues to rotate and does not fit and resist with the force transmission collision plate 20, the elastic force of the spring is instantly released. Then, the clog clearing rods 12 will strike and clear the blockage of the necked dust removal cloth bag 9. The entire cloth bag cleaning mechanism rotates on the positioning ring 1 to clear the blockage of the entire necked dust removal cloth bag 9.

[0061] The rotation transmission assembly 5 drives the ring gear A 22 to rotate through the output of the second drive motor 21. The second drive motor 21 is equipped with a reducer. The ring gear A 22 rotates to drive the ring gear B 24 meshing therewith to rotate. The ring gear B 24 drives the outer sleeve 23 to rotate, thereby driving the positioning ring 1 to rotate.

[0062] The bag end positioning conveying pipe 8 passes through the top partition 7, and an air suction fan 25 is fixedly installed on the top partition 7. The air suction fan 25 is installed with an exhaust pipe 26, and the exhaust pipe 26 extends to the outside of the dust collector body 2.

[0063] The gas filtered by the closed dust removal bag 9 is discharged from the upper bag end positioning conveying pipe 8, then enters the space above the top partition 7, is sucked in by the suction fan 25, and then discharged to the outside of the dust collector body 2 through the exhaust pipe 26. The external air that needs to be dust-removed and filtered also enters the interior of the dust collector body 2 through the suction force of the suction fan 25.

[0064] A guiding inclined surface 27 is provided on the force transmission collision plate 20 , and the guiding inclined surface 27 is movably matched with the elliptical collision block 18 .

[0065] The guiding inclined surface 27 can prevent the elliptical collision block 18 from getting stuck and guide the elliptical collision block 18 to rotate in a close fit.

[0066] The dust collector body 2 is provided with an air inlet 28 .

[0067] The gas to be dedusted enters the dust collector body 2 through the air inlet 28 .
