Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to a pulse filter cartridge dust collector. Background Technique

[0002] In the modern industrial production environment, a large amount of dust is generated in many production processes, such as the industries of mining, metallurgy, building materials, and chemical engineering. These dusts not only pose a threat to the physical health of operators, but may also cause safety accidents such as explosions, and at the same time cause serious environmental pollution. The effective treatment of dust is a crucial issue. With the continuous development of industrial technology, the requirements for the performance and efficiency of dust collectors are also getting higher and higher. For example, the Chinese patent document with the publication number CN213853549U discloses a pulse filter cartridge dust collector, which includes a primary dust removal box and a secondary dust removal box. An air inlet is provided on one side of the primary dust removal box, and an induced draft fan is provided on the other side of the primary dust removal box. It is characterized in that: the secondary dust removal box is fixedly installed above the primary dust removal box, the output end of the induced draft fan is communicated with one side of the inner cavity of the secondary dust removal box, an air outlet pipe is provided on the other side of the secondary dust removal box, a plurality of dust removal filter cartridges are hung inside both the primary dust removal box and the secondary dust removal box, a spray pipe is provided in the middle above the dust removal filter cartridges, air storage tanks are fixedly installed outside both the primary dust removal box and the secondary dust removal box, a plurality of electromagnetic pulse valves are communicated with the air storage tanks, the output end of the electromagnetic pulse valve is communicated with the spray pipe, a high-pressure air pump is provided outside the secondary dust removal box, the input end of the high-pressure air pump is communicated with the inner cavity of the air outlet pipe, and the output end of the high-pressure air pump is communicated with the two air storage tanks. In this way, the phenomenon of incomplete filtration in the case of more dust or stronger wind force is solved.

When the electric pulse valve is opened, the compressed gas in the high-pressure air pump instantly rushes into the filter cartridge, causing the dust attached to the surface of the filter cartridge to instantly fall to the dust discharge port below the box body, resulting in a large amount of dust accumulating at the dust discharge port below the box body instantly. And under the gravity of the falling, a large amount of dust is in a compacted state at the dust discharge port, resulting in difficult dust discharge. In view of this, the pulse filter cartridge dust collector of the present application is proposed. Content of the Utility Model

For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0036] Such as Figures 1 to 6As shown, in one embodiment, a pulse filter dust collector 1 includes a box body 10, a dust removal component 20 and a dust discharging component 30. An air inlet 11, an air outlet 12 and a dust discharging port 13 which are communicated with each other are provided on the box body 10. The dust removal component 20 is arranged inside the box body 10 and is used for filtering dust in the air. The dust discharging component 30 includes a connecting seat 31, a swinging piece 32, a centrifugal piece 33, a pull rod 34 and a driving component 35. The connecting seat 31 is arranged on the box body 10 and is communicated with the dust discharging port 13. The swinging piece 32 is rotatably arranged inside the connecting seat 31. The driving component 35 is arranged on the outer side wall of the connecting seat 31. The centrifugal piece 33 is arranged on the output end of the driving component 35. Two ends of the pull rod 34 are respectively rotatably connected with the swinging piece 32 and the centrifugal piece 33, so that the driving component 35 drives the swinging piece 32 to swing reciprocally.

[0037] It should be noted that an air inlet 11 is formed on one side surface of the box body 10, and an air outlet 12 is formed on the other side surface opposite to the air inlet 11. The air inlet 11 is located at the lower end of the side surface of the box body 10, and the air outlet 12 is located at the upper end of the other side surface of the box body 10. Further, the bottom of the box body 10 is of a funnel-shaped structure, and the dust discharging port 13 is formed at the bottom of the funnel-shaped structure. In this way, when the dust falls downward from the inside of the box body 10, the dust can gather along the inner side wall of the funnel-shaped structure to the bottom and be discharged from the dust discharging port 13. Further, the connecting seat 31 is arranged at the bottom of the box body 10 and is located at the lowest part of the funnel-shaped structure at the bottom of the box body 10. The connecting seat 31 is provided with an inner groove 311 which is communicated with the dust discharging port 13, so that the dust can be discharged from the inner groove 311. Further, the swinging piece 32 tends to be of a "T" shape. One end of the swinging piece 32 is rotatably arranged inside the connecting seat 31, and the other end of the swinging piece 32 extends into the dust discharging port 13. Further, the driving component 35 is of a motor structure. The driving component 35 is arranged on one of the outer side walls of the connecting seat 31. The centrifugal piece 33 is arranged on the output end of the driving component 35. Two ends of the pull rod 34 are respectively rotatably connected with the swinging piece 32 and the centrifugal piece 33. Further, the centrifugal piece 33 is of a circular ring structure. The center of the centrifugal piece 33 is connected with the output end of the driving component 35, and the circular ring structure of the centrifugal piece 33 is connected with one end of the pull rod 34. In this way, the centrifugal piece 33 drives one end of the pull rod 34 to rotate in a circular motion, so that the other end of the pull rod 34 can be reciprocally pushed and pulled, and further the driving component 35 can drive the swinging piece 32 to swing reciprocally. Since the other end of the swinging piece 32 is located inside the funnel-shaped structure at the bottom of the box body 10, the driving component 35 drives the swinging piece 32 to swing reciprocally inside the dust discharging port 13. In this way, when a large amount of dust instantaneously accumulates at the dust discharging port 13 and, under the gravity of the falling dust, a large amount of dust is in a compacted state at the dust discharging port 13, the swinging piece 32 can swing reciprocally inside the dust discharging port 13 to loosen the compacted dust, so that the dust accumulated at the dust discharging port 13 can be quickly discharged.

[0038] As shown Figures 4 to 6 In one embodiment, the swing member 32 includes a cross bar 321, a rocker 322 and a transmission block 323. The cross bar 321 is inserted through the connecting seat 31. The rocker 322 is disposed on the cross bar 321, and the cross bar 321 is located in the inner groove 311. The transmission block 323 is disposed at the end of the cross bar 321, and the transmission block 323 is rotatably connected to the pull rod 34.

[0039] It should be noted that the cross bar 321 is inserted through the connecting seat 31, and the cross bar 321 is located in the inner groove 311. The rocker 322 is disposed in the middle of the cross bar 321, so that one end of the rocker 322 is located in the inner groove 311, while the other end of the rocker 322 extends into the dust exhaust port 13. When the cross bar 321 rotates, the cross bar 321 will drive the rocker 322 to rotate, and then the other end of the rocker 322 will swing back and forth in the dust exhaust port 13. Further, one end of the transmission block 323 is disposed at any end of the cross bar 321, and the transmission block 323 and the rocker 322 are oppositely disposed with the cross bar 321 as the axis, and the transmission block 323 is located on the outer side wall of the connecting seat 31, and the other end of the transmission block 323 is rotatably connected to the pull rod 34. When the pull rod 34 pulls the other end of the transmission block 323, the transmission block 323 will drive the rocker 322 to rotate with the cross bar 321 as the axis, and then the centrifugal blade 33 will drive the rocker 322 to swing back and forth with the cross bar 321 as the axis. In this way, the dust accumulated in the dust exhaust port 13 can be quickly discharged.

[0040] As shown Figure 1 、 Figures 3 to 5 、 Figure 8 In one embodiment, the dust exhaust assembly 30 further includes a collection box 36, and the collection box 36 is snap-connected to the connecting seat 31.

[0041] It should be noted that the collection box 36 includes a box hopper 361 for collecting dust and a box cover 362. The box cover 362 is used to seal the box hopper 361 to prevent the dust in the box hopper 361 from flying out. A docking seat 3621 is provided at the top of the box cover 362, and the docking seat 3621 is snap-connected to the connecting seat 31. Further, a clamping strip 36211 is provided on the outer side wall of the docking seat 3621 to facilitate the snap connection between the collection box 36 and the connecting seat 31. Further, three of the side surfaces of the connecting seat 31 extend towards the collection box 36, so that one end of the inner groove 311 towards the collection box 36 is in a "U" shape, and the clamping groove 3111 is opened on the inner side wall of the "U" shape of the inner groove 311. The clamping strip 36211 on the docking seat 3621 is snap-connected to the clamping groove 3111 on the inner side wall of the inner groove 311, so that the collection box 36 is communicated with the dust discharge port 13, and further, the dust discharged from the dust discharge port 13 can enter the box hopper 361. Since the other end of the rocker 322 is located in the dust discharge port 13, when the driving member 35 drives the rocker 322 to swing reciprocally, the rocker 322 can stir the dust accumulated in the dust discharge port 13, so that the dust can be quickly discharged from the dust discharge port 13 and discharged into the collection box 36 through the inner groove 311.

[0042] It should be noted that since the clamping groove 3111 is opened on the inner side wall of the "U" shape of the inner groove 311, the clamping groove 3111 is also in a "U" shape. When the collection box 36 is snap-connected to the connecting seat 31, the dust can be discharged into the collection box 36 through the dust discharge port 13. After the dust in the collection box 36 is collected, the collection box 36 can be laterally slid out of the clamping groove 3111 directly to facilitate the installation and disassembly of the collection box 36.

[0043] As Figures 2 to 3 shown, in an embodiment, the dust removal assembly 20 includes a filter member 22. The filter member 22 is disposed in the box body 10, so that the box body 10 is divided into a first chamber 14 and a second chamber 15. The first chamber 14 is communicated with the air inlet 11 and the dust discharge port 13, and the second chamber 15 is communicated with the air outlet 12.

[0044] As Figures 2 to 3 shown, in an embodiment, the filter member includes a partition plate 221 and a plurality of filter elements 222. The partition plate 221 is disposed on the inner side wall of the box body 10, and each filter element 222 is disposed on the partition plate 221, and each filter element 222 is located in the first chamber 14.

[0045] It should be noted that the partition plate 221 is horizontally arranged on the inner side wall of the box body 10, and the four side surfaces of the partition plate 221 are all connected to the four inner side walls inside the box body 10, so that the inside of the box body 10 is divided into a first chamber 14 and a second chamber 15. The second chamber 15 is located above the first chamber 14, and the first chamber 14 is communicated with the air inlet 11 and the dust discharge port 13, and the second chamber 15 is communicated with the air outlet 12. Further, a plurality of through holes 2211 are formed in the partition plate 221, so as to form a communication between the first chamber 14 and the second chamber 15. The outlet ends of the respective filter elements 222 are respectively arranged at the opening positions of the respective through holes 2211, so that the gas needs to pass through the filter elements 222 when entering the second chamber 15 from the first chamber 14 for filtration.

[0046] It should be noted that the pulse filter cartridge dust collector 1 further includes an exhaust fan 40 and an exhaust duct 50. The exhaust fan 40 is located on one side surface of the pulse filter cartridge dust collector 1. The exhaust duct 50 is respectively connected to the air outlet 12 and the input end of the exhaust fan 40. Since the second chamber 15 is communicated with the air outlet 12, the exhaust fan 40 can drive the gas in the second chamber 15 to be discharged through the exhaust duct 50. And the second chamber 15 is also communicated with the first chamber 14, and the first chamber 14 is communicated with the air inlet 11, so that the exhaust fan 40 can drive the gas to flow in from the air inlet 11, pass through the filter elements 222 and then flow out from the air outlet 12. Further, because the first chamber 14 is communicated with the second chamber 15, when the gas with dust enters the first chamber 14 from the air inlet 11, it will flow to the second chamber 15. When the gas with dust passes through the filter elements 222, the dust will be separated by the filter elements 222 and adhere to the outer surface of the filter elements 222. And the respective filter elements 222 are located in the first chamber 14, so that the dust adhering to the surface of the filter elements 222 is also isolated in the first chamber 14. Since the first chamber 14 is also communicated with the discharge port, the dust can be discharged from the discharge port.

[0047] As Figure 4 , Figure 7 shown, in one embodiment, the dust discharge assembly 30 further includes a sealing plate 37 and a hand wheel 38. The sealing plate 37 is rotatably arranged on the inner side wall of the inner groove 311, and the hand wheel 38 is arranged on the sealing plate 37. The sealing plate 37 is used to seal or open the inner groove 311.

[0048] It should be noted that the sealing plate 37 is rotatably arranged on the inner side wall of the inner groove 311 and is located between the connecting seat 31 and the docking seat 3621. The handwheel 38 is arranged at one end of the sealing plate 37, and the handwheel 38 is located on an outer side wall of the connecting seat 31, so that the handwheel 38 can rotate the sealing plate 37 located on the inner side wall of the connecting seat 31 on the outer side wall of the connecting seat 31. Since the connecting seat 31 is arranged on the dust exhaust port 13 and the inner groove 311 of the connecting seat 31 is communicated with the dust exhaust port 13, rotating the handwheel 38 can seal the dust exhaust port 13 or open the dust exhaust port 13. Further, the air inlet 11 and the dust exhaust port 13 are both communicated with the first chamber 14. When the exhaust fan 40 works, gas can enter the first chamber 14 from the air inlet 11 and the dust exhaust port 13, which causes the dust falling into the dust exhaust port 13 to be brought back into the first chamber 14 and adhered to the filter element 222, reducing the dust removal efficiency of the pulse filter dust collector 1.

[0049] It should be noted that when the handwheel 38 is rotated to seal the dust exhaust port 13, the first chamber 14 can only be communicated with the air inlet 11. Thus, gas can only enter the first chamber 14 through the air inlet 11, and then the dust attached to the outer surface of the filter element 222 all comes from the gas at the air inlet 11. When the handwheel 38 is rotated to open the dust exhaust port 13, the dust exhaust port 13 is communicated with the collection box 36, and then the dust can be discharged into the collection box 36.

[0050] As Figures 1 to 2 shown, in an embodiment, the dust removal assembly 20 further includes an air tank 23, a plurality of solenoid valves 24 and a plurality of spray pipes 25. The air tank 23 is arranged on the box body 10, each solenoid valve 24 is arranged on the air tank 23, one end of each spray pipe 25 is respectively communicated with each solenoid valve 24, and the other end of each spray pipe 25 respectively extends to the opening position of each filter element 222.

[0051] It should be noted that the gas tank 23 is arranged on an outer side wall of the box body 10, each electromagnetic valve 24 is arranged on the gas tank 23, and one end of each spray pipe 25 is respectively communicated with each electromagnetic valve 24, so that the electromagnetic valve 24 can control the compressed gas in the gas tank 23 to enter the spray pipe 25. Further, the other ends of the spray pipes 25 respectively extend into the second chamber 15, and each spray pipe 25 is located above the opening position of each filter element 222, and the nozzles of the spray pipes 25 face the inner bottom wall of the filter element 222. Thus, when the electromagnetic valve 24 is opened, the compressed gas in the gas tank 23 can be instantaneously ejected from the nozzles of the spray pipes 25, so as to form a reverse air flow in the filter element 222, and then the dust attached to the outer surface of the filter element 222 can be instantaneously shed onto the dust discharge port 13 below the filter element 222. A large amount of dust will instantaneously fall onto the relatively small dust discharge port 13, making it impossible for the dust to be discharged in time. And due to the action of gravity and the characteristics of the dust, a large amount of dust will accumulate at the dust discharge port 13, blocking the dust discharge port 13. Thus, when the driving member 35 drives the rocker 322 to swing reciprocally, it can stir the dust accumulated at the dust discharge port 13, so that the dust can be quickly discharged from the dust discharge port 13.

[0052] As Figure 1 , Figure 3 shown, in one embodiment, the pulse filter cartridge dust collector 1 further includes a maintenance door 60. The maintenance door 60 is rotatably arranged on the box body 10, and a window 16 is further opened on one side surface of the box body 10, and the window is communicated with the first chamber 14. The maintenance door 60 is used to seal or open the first chamber 14, so as to facilitate the staff to repair or maintain the filter element 222 in the first chamber 14. Further, the maintenance door 60 includes a door panel 61 and a glass sheet 62. The glass sheet 62 is arranged on the door panel 61, so that the staff can observe the working conditions in the first chamber 14 through the glass sheet 62 outside the pulse filter cartridge dust collector 1, so as to improve the operation stability of the equipment.

[0053] The above embodiments only represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted 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.
