Description

Technical Field

[0001] This invention relates to the field of baghouse dust collector technology, and more particularly to a baghouse dust collector for use in fertilizer production and processing workshops. Background Technology

[0002] In fertilizer production and processing, processes such as crushing, mixing, screening, conveying, and granulation of raw materials generate a large amount of dust. To meet environmental emission standards and recover valuable materials, baghouse dust collectors, due to their high dust removal efficiency and stable performance, have become the core equipment for dust control in fertilizer production workshops. Both fertilizer raw materials and finished granules have strong hygroscopic properties. During dust removal, the dust-laden gas usually carries a certain temperature and humidity. When the temperature of the equipment casing or compressed air is lower than the flue gas dew point, condensation easily occurs on the surface of the filter bags. The moist dust adheres firmly to the surface of the filter bags, forming a dense, caked layer, known as "bag clogging." After clogging, the effective filtration area of ​​the filter bags decreases sharply, the operating resistance increases significantly, and system exhaust becomes obstructed.

[0003] Currently, most baghouse dust collectors used in fertilizer workshops adopt a single reverse air or pulse jet cleaning method. This type of airflow impact method is effective for dry and loose dust, but for fertilizer dust that has absorbed moisture or has a certain stickiness, it is difficult to effectively peel off the caking layer by relying solely on high-pressure gas. Even if the jet pressure is increased, the cleaning effect is still not ideal, and it is easy to damage the internal fibers of the filter bag, shortening the filter bag's life. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bag filter for fertilizer production and processing workshops.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A baghouse dust collector for fertilizer production and processing workshop includes a dust collection box, an air inlet pipe fixedly installed through the bottom of one side of the dust collection box, an end cover fixedly installed at the top of the dust collection box communicating with its interior, an exhaust pipe fixedly installed through the outer surface of the end cover, a ash discharge valve installed at the bottom of the dust collection box, and an mounting plate fixedly installed on the inner wall of the dust collection box near its top. The upper surface of the mounting plate has multiple through holes evenly distributed throughout. The dust collection box also includes: The filter bag is used to filter dust gas entering the dust collector from the air inlet pipe. An installation ring is fixedly installed on the lower surface of the mounting plate near the through hole, and the top of the filter bag is fixedly installed to the lower surface of the installation ring. A bag cage is installed at the through hole. The bag cage consists of a rotating ring, multiple support rods and a turntable. The multiple support rods are fixedly installed between the rotating ring and the turntable. The rotating ring is rotatably installed at the bottom of the mounting plate. The filter bag is sleeved on the outside of the bag cage. A cleaning mechanism, installed inside the bag cage, is used to clean dust from the surface of the filter bag.

[0006] As a further embodiment of the present invention, the cleaning mechanism includes a mounting frame fixedly installed on the inner wall of the through hole, a reciprocating screw fixedly installed at the bottom end of the center position of the mounting frame, the bottom end of the reciprocating screw penetrating the lower surface of the turntable and fixedly installed on a fixing plate, the bottom end of the filter bag being fixedly installed on the outer surface of the fixing plate, and a lifting assembly being installed on the outer side of the reciprocating screw.

[0007] As a further embodiment of the present invention, the lifting assembly includes a lifting plate slidably mounted on a support rod, the reciprocating lead screw passes through the outer surface of the lifting plate and is threadedly connected to it, and a striking assembly is installed on the outer surface of both ends of the lifting plate.

[0008] As a further embodiment of the present invention, the striking assembly includes a fixed plate fixedly installed at the bottom end of the lifting plate, a movable rod slidably installed through the outer surface of the fixed plate, a push plate fixedly installed at the end of the movable rod away from the reciprocating lead screw, rotating rods rotatably installed at both ends of the push plate via a torque shaft, a swing disk fixedly installed at the top end of the rotating rod, and multiple connecting rods uniformly rotatably installed in the circumferential direction at the top end of the swing disk, a striking block fixedly installed at the end of each connecting rod, and a power storage assembly installed between the rotating rod and the lifting plate.

[0009] As a further embodiment of the present invention, the power storage component includes a transmission gear installed on the outside of the rotating rod, a one-way bearing is installed between the transmission gear and the rotating rod, and a transmission rack is fixedly installed on the side of the lifting plate, wherein the transmission gear intermittently meshes with the transmission rack.

[0010] As a further embodiment of the present invention, the lifting plate is equipped with a toggle assembly for intermittently toggling a moving rod. The toggle assembly includes a roller rotatably mounted on the top of the lifting plate. The roller is in contact with the outer surface of the reciprocating lead screw. A dial is fixedly mounted at the rotation center of the roller. Multiple arc-shaped toggle blocks are fixedly mounted circumferentially on the lower surface of the dial. A toggle post is fixedly mounted on the outer surface of the moving rod near the end of the reciprocating lead screw.

[0011] As a further embodiment of the present invention, a compression spring is sleeved on the outer surface of the moving rod, and the compression spring is disposed between the fixed plate and the push plate.

[0012] As a further embodiment of the present invention, a follower assembly is installed on the inner side of the rotating ring. The follower assembly includes a plurality of fan-shaped holes evenly opened in the circumferential direction on the inner wall of the rotating ring.

[0014] The beneficial effects of this invention are as follows: 1. By setting up a cleaning mechanism, during the back-blowing operation, the lifting plate rotates and moves up and down under the drive of the reciprocating screw, which drives the beating block to perform high-frequency, multi-angle mechanical beating on the surface of the filter bag. Combined with the back-blowing airflow of the air pipe and nozzle, it can powerfully remove the caking dust that adheres to the surface of the filter bag due to the moisture absorption of fertilizer dust, effectively solving the industry problem of easy bag clogging in fertilizer workshops and greatly extending the service life of the filter bag. 2. During dust removal, the lifting plate moves up and down along the reciprocating screw, so that the beating blocks on it can reciprocate to beat the filter bag from top to bottom or from bottom to top, ensuring that the accumulated dust on all parts of the filter bag surface can be cleaned, the force is even, and the filter material is not damaged due to excessive local dust removal. 3. By tapping the filter bags with the tapping blocks and back-blowing the nozzles, the dust on the surface of the filter bags can be cleaned in time, ensuring that the filter bags always maintain good air permeability. This effectively controls the operating resistance inside the dust collector, ensures the air intake of the inlet pipe and the exhaust efficiency of the outlet pipe, and ensures normal ventilation and dust removal in the fertilizer production line.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] See attached document Figure 1 - Appendix Figure 11 A baghouse dust collector for fertilizer production and processing workshop includes a dust collection box 1, an air inlet pipe 2 fixedly installed through the bottom of one side of the dust collection box 1, an end cover 6 fixedly installed at the top of the dust collection box 1 communicating with its interior, an exhaust pipe 3 fixedly installed through the outer surface of the end cover 6, a dust discharge valve 4 installed at the bottom of the dust collection box 1, and an mounting plate 5 fixedly installed on the inner wall of the dust collection box 1 near its top. The upper surface of the mounting plate 5 has multiple through holes 10 evenly distributed throughout. The dust collection box 1 also includes: The filter bag 15 is used to filter the dust gas entering the dust collector 1 from the air inlet pipe 2. The mounting plate 5 is fixedly installed with the mounting ring 11 near the lower surface of the through hole 10. The top of the filter bag 15 is fixedly installed with the lower surface of the mounting ring 11. The bag cage is installed at the through hole 10. The bag cage consists of a rotating ring 16, multiple support rods 17 and a turntable 18. The multiple support rods 17 are fixedly installed between the rotating ring 16 and the turntable 18. The rotating ring 16 is rotatably installed at the bottom of the mounting plate 5. The filter bag 15 is sleeved on the outside of the bag cage. When in use, the dust gas from the fertilizer production workshop is discharged into the dust collector 1 through the air inlet pipe 2. The dust gas will be intercepted and filtered by the filter bag 15, and the filtered clean gas will be discharged to the outside through the exhaust pipe 3.

[0020] In this embodiment, multiple air blowing pipes 7 are fixedly installed between the inner walls of opposite sides of the end cap 6. Nozzles 8 corresponding to the through holes 10 are installed on the outer surface of the air blowing pipes 7. Air bags 9 are fixedly installed between the ends of the multiple air blowing pipes 7.

[0021] When it is necessary to clean the dust on the surface of the filter bag 15, the compressed gas in the air tank 9 is blown out through the air pipe 7 and the nozzle 8 to achieve back-blowing cleaning of the filter bag 15 and blow off the dust on the surface of the filter bag 15.

[0022] The cleaning mechanism is installed inside the bag cage and is used to clean the dust on the surface of the filter bag 15.

[0023] In this embodiment, the cleaning mechanism includes a mounting bracket 12 fixedly installed on the inner wall of the through hole 10. A reciprocating screw 13 is fixedly installed at the bottom of the center of the mounting bracket 12. The bottom end of the reciprocating screw 13 passes through the lower surface of the turntable 18 and is fixedly installed on a fixed plate 14. The bottom end of the filter bag 15 is fixedly installed on the outer surface of the fixed plate 14. A lifting assembly is installed on the outside of the reciprocating screw 13. The lifting assembly includes a lifting plate 19 slidably installed on the support rod 17. The reciprocating screw 13 passes through the outer surface of the lifting plate 19 and is threadedly connected to it. Beating assemblies are installed on the outer surfaces of both ends of the lifting plate 19. The beating assembly includes a fixed plate 20 fixedly installed at the bottom of the lifting plate 19. A moving rod 21 is slidably installed through the outer surface of the fixed plate 20. The moving rod 21 is away from the reciprocating screw 13. A push plate 22 is fixedly installed at one end of the 3. Both ends of the push plate 22 are rotatably mounted with rotating rods 28 via torque shafts. A swing disk 31 is fixedly installed at the top of the rotating rod 28. Multiple connecting rods 32 are evenly mounted on the top of the swing disk 31 in the circumferential direction. A striking block 33 is fixedly installed at the end of each connecting rod 32. A power storage component is installed between the rotating rod 28 and the lifting plate 19. The power storage component includes a transmission gear 30 installed on the outside of the rotating rod 28. A one-way bearing 29 is installed between the transmission gear 30 and the rotating rod 28. A transmission rack 34 is fixedly installed on the side of the lifting plate 19. The transmission gear 30 intermittently meshes with the transmission rack 34. A compression spring 24 is sleeved on the outer surface of the moving rod 21. The compression spring 24 is located between the fixed plate 20 and the push plate 22.

[0024] During backflushing, the blade 36 flips downward under the action of the counterweight 37, forming an inclined state inside the rotating ring 16. At this time, the backflushing gas will impact the blade 36, causing the blade 36 to drive the rotating ring 16 to rotate, thereby causing the entire bag cage to rotate, while the filter bag 15 remains stationary under the action of the mounting ring 11 and the fixing plate 14. When the rotating ring 16 drives the support rod 17 to rotate, the support rod 17 will drive the lifting plate 19 to rotate. Since the lifting plate 19 is threadedly connected to the reciprocating screw 13, the lifting plate 19 will also move up and down along the axis of the reciprocating screw 13 while rotating. When the lifting plate 19 rotates and moves, the roller 25 installed on it will roll on the outer circumference of the reciprocating screw 13, causing the roller 25 to drive the dial 26 to rotate, so that the arc-shaped dial block 27 installed at the bottom of the dial 26 can intermittently pull and release the moving rod 21 through the dial post 23. When the moving rod 21 is pulled, it will push the plate 22 and the rotating rod 28 drive the swing disk 31 to move as a whole. At this time, the transmission gear 30 installed on the outside of the rotating rod 28 through the one-way bearing 29 can only roll on the transmission rack 34 and will not drive the rotating rod 28 to rotate. When the arc-shaped lever 27 releases the lever 23, the push plate 22 will be pushed outward under the elastic force of the compression spring 24. At this time, the transmission gear 30 reverses on the transmission rack 34, so that the transmission gear 30 can drive the rotating rod 28 to rotate through the one-way bearing 29, so that the torque shaft installed between the rotating rod 28 and the push plate 22 is twisted. After the transmission gear 30 and the transmission rack 34 are separated, the rotating rod 28 will drive the swing disk 31 to rotate rapidly under the torsion of the torque shaft, so that the striking block 33 installed on the top of the swing disk 31 through the connecting rod 32 is thrown outward under the action of centrifugal force, so that the striking block 33 can beat the filter bag 15 to knock off the dust adhering to the surface of the filter bag 15.

[0025] In this embodiment, a toggle assembly for intermittently toggling the moving rod 21 is installed on the lifting plate 19. The toggle assembly includes a roller 25 rotatably mounted on the top of the lifting plate 19. The roller 25 is in contact with the outer surface of the reciprocating lead screw 13. A dial 26 is fixedly mounted at the rotation center of the roller 25. Multiple arc-shaped toggle blocks 27 are fixedly mounted on the lower surface of the dial 26 in the circumferential direction. A toggle post 23 is fixedly mounted on the outer surface of the moving rod 21 near the end of the reciprocating lead screw 13.

[0026] In use, the intermittent actuation structure of the dial 26, the arc-shaped lever 27, and the lever 23, combined with the stored and released force of the compression spring 24, and the unidirectional transmission characteristics of the one-way bearing 29 and the transmission gear 30, makes the striking action of the striking block 33 intermittent and sudden. This intermittent strong impact is more effective than continuous vibration in breaking down the adhesion of dust, resulting in a better dust removal effect.

[0027] In this embodiment, a follower component is installed on the inner side of the rotating ring 16. The follower component includes a plurality of fan-shaped holes 35 evenly opened in the circumferential direction on the inner wall of the rotating ring 16. A blade 36 is rotatably installed on the inner wall of the fan-shaped holes 35. A counterweight 37 is fixedly installed on the outer surface of the side of the blade 36 that is flipped downward.

[0028] During dust removal, the filtered gas flows upward, which blows the blades 36 upward and makes them vertical so that the filtered gas can be discharged. When the filter bag 15 is back-blown, the back-blowing gas blows downward, which blows the blades 36 downward. At the same time, the blades 36 will also flip downward under the weight of the counterweight 37, so that multiple blades 36 form an impeller structure inside the rotating ring 16. As can be seen from the above description, the above embodiments of the present invention achieve the following technical effects: When in use, the dust gas in the fertilizer production workshop is discharged into the dust collection box 1 through the air inlet pipe 2. The dust gas will be intercepted and filtered by the filter bag 15, and the filtered clean gas is discharged to the outside through the exhaust pipe 3. When it is necessary to clean the dust on the surface of the filter bag 15, the compressed gas in the air tank 9 is blown out through the air pipe 7 and the nozzle 8 to achieve back-blowing cleaning of the filter bag 15 and blow off the dust on the surface of the filter bag 15. During backflushing, the blade 36 flips downward under the action of the counterweight 37, forming an inclined state inside the rotating ring 16. At this time, the backflushing gas will impact the blade 36, causing the blade 36 to drive the rotating ring 16 to rotate, thereby causing the entire bag cage to rotate, while the filter bag 15 remains stationary under the action of the mounting ring 11 and the fixing plate 14. When the rotating ring 16 drives the support rod 17 to rotate, the support rod 17 will drive the lifting plate 19 to rotate. Since the lifting plate 19 is threadedly connected to the reciprocating screw 13, the lifting plate 19 will also move up and down along the axis of the reciprocating screw 13 while rotating. When the lifting plate 19 rotates and moves, the roller 25 installed on it will roll on the outer circumference of the reciprocating screw 13, causing the roller 25 to drive the dial 26 to rotate, so that the arc-shaped dial block 27 installed at the bottom of the dial 26 can intermittently pull and release the moving rod 21 through the dial post 23. When the moving rod 21 is pulled, it will push the plate 22 and the rotating rod 28 drive the swing disk 31 to move as a whole. At this time, the transmission gear 30 installed on the outside of the rotating rod 28 through the one-way bearing 29 can only roll on the transmission rack 34 and will not drive the rotating rod 28 to rotate. When the arc-shaped lever 27 releases the lever 23, the push plate 22 will be pushed outward under the elastic force of the compression spring 24. At this time, the transmission gear 30 reverses on the transmission rack 34, so that the transmission gear 30 can drive the rotating rod 28 to rotate through the one-way bearing 29, so that the torque shaft installed between the rotating rod 28 and the push plate 22 is twisted. After the transmission gear 30 and the transmission rack 34 are separated, the rotating rod 28 will drive the swing disk 31 to rotate rapidly under the torsion of the torque shaft, so that the striking block 33 installed on the top of the swing disk 31 through the connecting rod 32 is thrown outward under the action of centrifugal force, so that the striking block 33 can beat the filter bag 15 to knock off the dust adhering to the surface of the filter bag 15.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
