[0043] As Figures 1 to 15 shown, in one embodiment, a pulse bag filter 1 includes a dust removal box 10, a dust suction assembly 20 and a cleaning assembly 30. A partition plate 11 is arranged in the dust removal box 10. The partition plate 11 divides the dust removal box 10 into a dust removal chamber 12 and a cleaning chamber 13. The cleaning chamber 13 is located above the dust removal chamber 12. The dust suction assembly 20 includes a plurality of cloth bags 21 and a plurality of brackets 22. Each bracket 22 is arranged on the partition plate 11. Each cloth bag 21 is respectively sleeved on each bracket 22, and each cloth bag 21 and each bracket 22 are both located in the dust removal chamber 12. The cleaning assembly 30 includes a gas control member 31, a conduit 32, a spray pipe 33 and a connecting member 34. The gas control member 31 is arranged on the outer side wall of the dust removal box 10. One end of the conduit 32 is arranged on the gas control member 31, and the other end of the conduit 32 is located in the cleaning chamber 13. One end of the spray pipe 33 is rotatably arranged on the conduit 32, and the other end of the spray pipe 33 is located inside the cloth bag 21. The connecting member 34 is respectively clamped to the conduit 32 and the spray pipe 33. A plurality of inclined holes 331 are formed in the spray pipe 33. The inclined holes 331 are equally spaced on the spray pipe 33, and the inclined holes 331 are arranged along the same circumferential direction of the spray pipe 33 with the axis of the spray pipe 33 as the center. When the gas jets out from the inclined holes 331, the gas drives the spray pipe 33 to rotate with the spray pipe 33 as the axis, so that the gas can be evenly sprayed on the inner side wall of the cloth bag 21.

[0044] It should be noted that a plurality of through holes are formed in the partition plate 11. When the partition plate 11 divides the dust removal box 10 into a dust removal chamber 12 and a cleaning chamber 13, the inside of the dust removal chamber 12 and the cleaning chamber 13 can be communicated, so that gas can flow from the dust removal chamber 12 into the cleaning chamber 13. Further, the dust removal box 10 is provided with an air inlet 14, an air outlet 15 and a dust collection port 16. The air inlet 14 is formed on the side surface of the dust removal box 10, the dust collection port 16 is formed at the bottom of the dust removal box 10, and both the air inlet 14 and the dust collection port 16 are communicated with the dust removal chamber 12. The air outlet 15 is formed on the other side surface of the dust removal box 10, and the air outlet 15 is communicated with the cleaning chamber 13. In this way, the gas entering the dust removal chamber 12 from the air inlet 14 can flow into the cleaning chamber 13 through a plurality of through holes, and then be discharged from the air outlet 15 to form a connected gas passage.

[0045] It should be noted that the dust suction assembly 20 includes a plurality of cloth bags 21 and a plurality of brackets 22. Each bracket 22 is arranged on the partition plate 11, and the opening of each bracket 22 is connected to each through hole on the partition plate 11, and each cloth bag 21 is sleeved on the outer side wall of each bracket 22, and each bracket 22 and each cloth bag 21 are both located in the dust removal chamber 12.

[0046] It should be noted that the pulse cloth bag dust collector 1 further includes an exhaust fan. The exhaust fan is communicated with the air outlet 15 through a ventilation duct. When the exhaust fan pumps the gas in the cleaning chamber 13, the gas in the dust removal chamber 12 flows into the cleaning chamber 13 through each through hole. Since the opening of each bracket 22 is connected to each through hole on the partition plate 11, and each cloth bag 21 is sleeved on the outer side wall of each bracket 22, the gas needs to pass through each cloth bag 21 before it can flow into the cleaning chamber 13. It should be noted that when the gas flows into the cleaning chamber 13 through the cloth bag 21, the gas will squeeze the cloth bag 21, resulting in the cloth bag 21 being unable to unfold. Therefore, the opening of each bracket 22 is connected to each through hole on the partition plate 11, and each cloth bag 21 is sleeved on the outer side wall of each bracket 22 to prevent each cloth bag 21 from being deformed by the airflow, thus affecting the filtration effect. When the gas passes through each unfolded cloth bag 21, the dust carried by the gas will be isolated and adsorbed on the outer side wall of each cloth bag 21, and the gas filtered from the dust will be discharged from the air outlet 15 through the cleaning chamber 13.

[0047] It should be noted that the air control component 31 includes an air storage tank 311 and a plurality of pulse solenoid valves 312. One end of the air storage tank 311 is communicated with an air compressor, so that the compressed gas is stored in the air storage tank 311, and each pulse solenoid valve 312 is connected to the air outlet end of the air storage tank 311.

[0048] It should be noted that there are multiple conduits 32, and one end of each conduit 32 is connected to each pulse solenoid valve 312. When the pulse solenoid valve 312 is opened, the compressed gas in the air storage tank 311 can enter each conduit 32. Further, there are also multiple spray nozzles 33. One end of each spray nozzle 33 is rotatably connected to each conduit 32 in a one-to-one correspondence, and one end of each spray nozzle 33 is communicated with each conduit 32, so that the gas in each conduit 32 can enter the interior of each spray nozzle 33. Further, a plurality of inclined holes 331 are formed on the outer side wall of each spray nozzle 33, and each inclined hole 331 is communicated with the interior of the spray nozzle 33. The other end of each spray nozzle 33 is not provided with an opening, so that the gas in the conduit 32 can only be ejected from each inclined hole 331 after entering the interior of the spray nozzle 33. Since the inclined holes 331 are equidistantly distributed on the spray nozzle 33 and are arranged along the same circumferential direction of the spray nozzle 33 with the axis of the spray nozzle 33 as the center, when the gas is ejected from each inclined hole 331, the gas drives the spray nozzle 33 to rotate with the spray nozzle 33 as the axis, so that the gas can be evenly sprayed on the inner side wall of the cloth bag 21.

[0049] As Figure 5 , Figures 12 to 13 shown, in one embodiment, each inclined hole 331 is arranged along the circumferential clockwise direction of the spray nozzle 33 with the axis of the spray nozzle 33 as the center, and each inclined hole 331 faces the same direction. When the gas is ejected from each inclined hole 331, a reverse air flow is formed in the cloth bag 21 to expand, and at the same time, the air flow is ejected from the inside of the cloth bag 21 to the outside of the cloth bag 21, so that the dust attached to the outer side wall of the cloth bag 21 falls off. At the same time, a reaction force is formed by the gas with the spray nozzle 33 as the axis, so that the gas ejected from each inclined hole 331 drives the spray nozzle 33 to rotate counterclockwise with the axis of the spray nozzle 33 as the center. In this way, the gas can be sprayed on the inner side wall of the cloth bag 21 in a rotating manner.

[0050] As Figure 5 , Figures 12 to 13 shown, in one embodiment, each inclined hole 331 is arranged along the circumferential counterclockwise direction of the spray nozzle 33 with the axis of the spray nozzle 33 as the center, and each inclined hole 331 faces the same direction. When the gas is ejected from each inclined hole 331, a reverse air flow is formed in the cloth bag 21 to expand, and at the same time, the air flow is ejected from the inside of the cloth bag 21 to the outside of the cloth bag 21, so that the dust attached to the outer side wall of the cloth bag 21 falls off. At the same time, a reaction force is formed by the gas with the spray nozzle 33 as the axis, so that the gas ejected from each inclined hole 331 drives the spray nozzle 33 to rotate clockwise with the axis of the spray nozzle 33 as the center. In this way, the gas can be sprayed on the inner side wall of the cloth bag 21 in a rotating manner.

[0051] It should be noted that since a plurality of inclined holes 331 are formed in the nozzle 33 and the inclined holes 331 are equally spaced on the nozzle 33, when the nozzle 33 rotates, gas can be evenly ejected against the inner sidewall of the cloth bag 21, so that a uniform reverse air flow is formed in the cloth bag 21, thereby uniformly cleaning the dust adsorbed on the outer sidewall of the cloth bag 21. Further, since the inclined holes 331 are equally spaced on the nozzle 33, when the nozzle 33 rotates, after one of the inclined holes 331 ejects against one position of the inner sidewall of the cloth bag 21, the ejected gas will push one position of the inner sidewall of the cloth bag 21 to bulge outward. As the nozzle 33 rotates, when the current inclined hole 331 moves to other positions, the inner sidewall of the cloth bag 21 returns to its original state because it does not receive the ejection of gas. At the same time, the nozzle 33 also drives another inclined hole 331 to move to the current position. When the other inclined hole 331 moves to the current position, the gas ejected by it will also cause the outer sidewall of the cloth bag 21 to bulge, so that an intermittent ejection frequency appears at one position of the inner sidewall of the cloth bag 21. Thus, when the nozzle 33 continuously rotates rapidly, multiple intermittent rapid ejection frequencies are formed at multiple positions on the inner sidewall of the cloth bag 21, thereby causing the cloth bag 21 to vibrate at a high frequency, so that the dust adsorbed on the outer sidewall of the cloth bag 21 can fall off evenly and quickly.

[0052] As Figure 2 、 Figures 6 to 9 shown, in one embodiment, a notch 3211 is formed in the conduit 32, and the notch 3211 is clamped with the connecting member 34.

[0053] It should be noted that a plurality of bayonet portions 321 are provided on the conduit 32. The inner diameter and outer diameter of each bayonet portion 321 are the same as the inner diameter and outer diameter of the conduit 32, and the outer diameter of one end of the nozzle 33 is the same as the inner diameter of the bayonet portion 321, so that the nozzle 33 can be inserted into the bayonet portion 321, and thus the nozzle 33 can rotate relative to the conduit 32. Grooves 3211 are formed on both sides of the bayonet portion 321, and the two grooves 3211 are formed from the outer sidewall of the bayonet portion 321 to the inner sidewall, so that both sides of the bayonet portion 321 are communicated, and at the same time, the bayonet portion 321 has an "I"-shaped structure.

[0054] As Figure 2 、 Figures 8 to 11 shown, in one embodiment, a circular groove 332 is formed at one end of the nozzle 33, and the connecting member 34 is also clamped with the circular groove 332.

[0055] It should be noted that a circular groove 332 is provided on one end of the nozzle 33 connected to the bayonet portion 321. The circular groove 332 starts along the circumferential direction of the outer wall of the nozzle 33, so that the circular groove 332 is in a circular ring shape, and at the same time, one end of the nozzle 33 is also in an "I"-shaped structure. Further, since the outer diameter of one end of the nozzle 33 is consistent with the inner diameter of the bayonet portion 321, the "I"-shaped structure of one end of the nozzle 33 can be inserted into the bayonet portion 321 and can overlap with the "I"-shaped structure of the bayonet portion 321, so that the connecting member 34 can be simultaneously inserted into the circular groove 332 and the two notches 3211, so that the nozzle 33 cannot be separated from the connecting port. Further, since the circular notches 3211 are in a circular ring shape, after the connecting member 34 is inserted into the circular groove 332, the nozzle 33 can rotate around the bayonet portion 321 as the center, so that the nozzle 33 can rotate relative to the guide tube 32.

[0056] like Figure 2 , Figure 5 , Figure 7 , Figures 14 to 15 As shown, in one embodiment, the connecting member 34 includes a block 341, a toggle plate 342 and an elastic member 343. The toggle plate 342 is rotatably disposed on the block 341. The elastic member 343 is disposed on the block 341, and the elastic member 343 is used to push the toggle plate 342 to engage with the conduit 32.

[0057] It should be noted that the block 341 is a U-shaped structure, and the shapes of the two ends of the block 341 are consistent with the shapes of the two notches 3211, so that the block 341 can be completely accommodated in the notches 3211 on both sides of the bayonet portion 321. Further, since the "I"-shaped structure at one end of the nozzle 33 can overlap with the "I"-shaped structure of the bayonet portion 321, the block 341 is completely accommodated in the two notches 3211 and is also accommodated in the circular groove 332 of the nozzle 33, thereby making it impossible for the nozzle 33 to be pulled out of the bayonet portion 321. Further, since the circular groove 332 is a circular ring structure, the block 341 can only be inserted into two opposite cut surfaces of the circular groove 332, and the two inner side surfaces of the block 341 can slide along the inner circumferential surface of the circular groove 332, so that the circular groove 332 can rotate while the block 341 is engaged, thereby making the nozzle 33 rotate relative to the conduit 32.

[0058] It should be noted that the toggle piece 342 tends to be a "7"-shaped structure, and there are two toggle pieces 342, which are respectively rotatably arranged on both sides of the block 341, and the inner side walls of the two toggle pieces 342 are both facing the block 341, so that the angled portions 3421 of the two toggle pieces 342 are both facing the bayonet portion 321, and the two toggle pieces 342 clamp the bayonet portion 321 of the conduit 32 together, so that the block 341 cannot be disengaged when it is engaged with the circular groove 332 and the two notches 3211. Further, the elastic member 343 is a spring structure, and there are two elastic members 343, one end of the two elastic members 343 is arranged on the two side surfaces of the block 341, and the other ends of the two elastic members 343 push the toggle pieces 342 on the two side surfaces of the block 341 respectively, so that the angled portions 3421 of the two toggle pieces 342 are engaged with the bayonet portion 321.

[0059] like Figure 9 , Figures 14 to 15 As shown, in one embodiment, a locking groove 322 is formed on the conduit 32 , and the elastic member 343 is used to push one end of the toggle piece 342 so that the other end of the toggle piece 342 is accommodated in the locking groove 322 .

[0060] It should be noted that two locking grooves 322 are provided on the bayonet portion 321, and the two locking grooves 322 are respectively located at the openings of the two notches 3211, and the two locking grooves 322 are cross-opened with the two notches 3211, and the two locking grooves 322 are at a 90-degree angle with the two notches 3211. Furthermore, two side surfaces of the clamping block 341 are provided with air-avoiding grooves 3411, and the opening direction and opening depth of the two air-avoiding grooves 3411 are consistent with those of the two locking grooves 322. When the clamping block 341 is clamped with the circular groove 332 and the two notches 3211, the air-avoiding groove 3411 and the locking groove 322 are both on the same plane, so that the air-avoiding groove 3411 and the locking groove 322 are merged into a connected clamping groove. At the same time, the block 341 will also drive the corner portion 3421 of the toggle piece 342 to slide to the slot, and the corner portion 3421 will be accommodated in the slot under the push of the elastic member 343. It should be noted that the width of the corner portion 3421 of the toggle piece 342 is consistent with the width of the slot, so that the corner portion 3421 of the toggle piece 342 can be accommodated in the air avoidance groove 3411 and the locking groove 322 at the same time. In this way, the air avoidance groove 3411 and the locking groove 322 are always kept combined and cannot be separated, so that the block 341 can wrap and hold the bayonet portion 321 of the conduit 32, so that the nozzle 33 can be connected to the conduit 32 while the nozzle 33 can be rotated.

[0061] like Figure 2 , Figure 5 , Figure 7 , Figures 14 to 15 As shown, in one embodiment, a pull ring 3412 is provided on the clamping block 341 .

[0062] It should be noted that the pull ring 3412 is provided at one end of the clamping block 341 away from the "U"-shaped opening. In this way, when the staff simultaneously presses two toggles 342 to drive the angled portion 3421 away from the card slot, the pull ring 3412 can be pulled to move the clamping block 341 away from the circular groove 332 and the two slots 3211, so that the nozzle 33 can be separated from the bayonet portion 321 of the conduit 32, facilitating the staff to disassemble and perform maintenance.

[0063] As Figures 4 to 5 shown, in one embodiment, the cleaning assembly 30 further includes a support bar 35. The support bar 35 is arranged on the partition plate 11, and the conduit 32 is arranged on the support bar 35.

[0064] It should be noted that there are multiple support bars 35. Each support bar 35 is located between each perforation, and the arrangement direction of each support bar 35 is perpendicular to the arrangement direction of each conduit 32, so that when each support bar 35 intersects with each conduit 32, it forms a "cross" shape. A plurality of U-shaped top seats 351 are provided on the support bar 35. The axis of the U-shaped top seat 351 is parallel to the axis of the conduit 32, so that the two side walls of the U-shaped top seat 351 can be clamped with the outer side wall of the conduit 32, and then each conduit 32 can be fixed on each support bar 35, increasing the stable connection between each conduit 32 and the dust removal box 10, avoiding the violent shaking of each conduit 32 when each nozzle 33 rotates, and improving the use safety and self-cleaning efficiency of the pulse bag filter 1.

[0065] The above embodiments only represent several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
