Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to an online pulse bag dust collector. Background Technology

[0002] The pulse jet baghouse dust collector consists of a dust hopper, upper chamber, middle chamber, and lower chamber, with the upper, middle, and lower chambers being compartmentalized. During operation, dust-laden gas enters the dust hopper through the inlet duct. Coarse dust particles fall directly to the bottom of the hopper, while fine dust particles are carried upwards by the airflow into the middle and lower chambers, where they accumulate on the outer surface of the filter bags. The filtered gas then enters the upper chamber and flows through the clean air collection pipe-exhaust duct, before being discharged to the atmosphere by the exhaust fan. The cleaning process begins by cutting off the clean air outlet duct of the corresponding chamber, placing the filter bags in a state of no airflow (compartmentalized stop-air cleaning). Then, the pulse valve is opened, and compressed air is used for pulse-jet cleaning. The valve closing time is sufficient to ensure that the dust detached from the filter bags settles into the dust hopper after the pulse jet, preventing dust from re-attaching to adjacent filter bags after detachment. This ensures thorough cleaning of the filter bags. A programmable logic controller (PLC) provides fully automatic control of the exhaust valve, pulse valve, and dust discharge valve. The invention patent with publication number CN114602250A discloses a high-efficiency and clean pulse bag dust collector, including a support frame, an integrated dust hopper, a dust collection box, and an upper box; the upper box is provided with a flip-top plate and a clean air outlet; a tube sheet is fixed inside the dust collection box and a venturi tube is provided on the tube sheet, and multiple dust collection filter bags and filter bag frames are provided on the lower end face of the tube sheet; a dust discharge plate is vertically mounted inside the dust collection box and has multiple through holes; a frame is fixed at the bottom of the dust collection box and multiple sealing plates are fixed inside the frame; a discharge valve and a dust inlet are provided at the bottom of the dust hopper. This invention forces gas containing impurities into the ash hopper by raising and lowering the dust discharge plate, preventing secondary contamination of the dust collector filter bags by the gas containing impurities. Operators can immediately and directly handle the impurities, saving a lot of time and thus completing the dust removal work efficiently and quickly. However, the ash on the ash hopper still cannot be automatically cleaned. If the ash on the ash hopper is not cleaned in time, it will cause the ash on the ash hopper to fall back onto the filter bags, resulting in problems such as low filtration efficiency of the filter bags. Utility Model Content

[0003] The purpose of this invention is to provide an online pulse bag dust collector that can clean the dust hopper in a timely manner and can handle multiple dust hoppers together.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an online dust removal pulse bag filter includes a frame and a bag filter body mounted on the frame. The bag filter body has a dust collection hopper below it and a dust discharge port below the dust collection hopper. A blade assembly is disposed in the dust discharge port. A drive unit is disposed on the frame. The drive unit controls the rotation of the blade assembly. The blade assembly includes a rotating shaft and a plurality of rotating blades radially disposed on the rotating shaft. The drive unit drives the rotating shaft to rotate, thereby causing the rotating blades to rotate.

[0005] By adopting the above technical solution, it is possible to clean the dust in the ash collection hopper below the bag filter. Regular cleaning can reduce the amount of dust in the ash collection hopper flowing back into the bag filter.

[0006] A further configuration of this utility model is as follows: the driving component includes a driving rod, a driving bevel gear, a control bevel gear, a driving frame, a driving gear, and a control component. The driving frame is mounted on the frame body, the driving gear is rotatably connected to the driving frame, the control component controls the rotation of the driving gear, the driving rod is coaxially fixedly connected to the driving gear, a plurality of driving bevel gears are coaxially fixedly connected to the driving rod, the control bevel gear is coaxially fixedly connected to the rotating shaft, and the driving bevel gear meshes with the control bevel gear.

[0007] By adopting the above technical solution, the control component controls the rotation of the drive gear, the drive gear drives the drive rod to rotate, the drive rod controls the rotation of three drive bevel gears set on the drive rod, the drive bevel gears further drive the rotation of the control bevel gears, the control bevel gears are fixedly connected to the rotating shaft, the rotation of the rotating shaft will drive the rotating blades to rotate, the six rotating blades are evenly distributed so that a dust collection bin is formed between two adjacent rotating blades, the dust inside will fall between two rotating blades, when rotating, the dust collection bin between the next two blades at the ash discharge port rotates to the ash discharge point, the collected dust collection bin rotates downwards, gradually rotates to the bottom and falls into the bottom for unified recycling.

[0008] A further feature of this invention is that the control component includes a drive motor, a control wheel, and a control lever. The drive motor is mounted on the drive frame, the control wheel is rotatably connected to the drive frame and coaxially fixedly connected to the output end of the drive motor, one end of the control lever is eccentrically rotatably connected to the control wheel, and the other end is provided with a rack, which meshes with the drive gear.

[0009] A further feature of this invention is that the control wheel has an annular groove, the annular groove including an inner annular groove and an outer annular groove, the inner annular groove being connected to the outer annular groove, and the distance from the inner annular groove to the axis of the control hole being less than the distance from the outer annular groove to the axis of the control hole.

[0010] A further feature of this invention is that one end of the control lever is located between the annular groove on the control wheel and the axis of the control wheel.

[0011] A further feature of this invention is that: a limiting rod is provided on the drive frame, the middle part of the limiting rod is rotatably connected to the drive frame, one end of the limiting rod is rotatably provided with an insert rod, the insert rod is movably inserted into the annular groove, and the other end is rotatably provided with a locking block, the locking block is provided with a locking groove, and the control rod is provided with a locking strip above the rack, the locking strip is slidably locked into the locking groove.

[0012] A further feature of this invention is that a limiting plate is provided at the end of the limiting rod on the other side of the snap-fit ​​block, and a strip-shaped hole is provided at the upper end of the limiting plate, with the end of the limiting rod movably disposed within the strip-shaped hole.

[0013] A further feature of this invention is that a locking tooth is provided below the limiting plate, and during the rotation of the control wheel, the locking tooth on the limiting plate meshes with the drive gear.

[0014] A further feature of this invention is that a guide block is fixedly mounted on the drive frame. The guide block includes an inner guide block and an outer guide block. The inner guide block is in contact with both sides of the inner wall of the limiting plate, and the outer guide block is in contact with both sides of the outer wall of the limiting plate.

[0015] By adopting the above technical solution, when the drive gear rotates, the locking teeth on the limiting plate release the drive gear; when the drive gear does not rotate, the locking teeth engage and limit the drive gear. When the control wheel rotates, the control rod eccentrically connected to the rotating wheel will move left and right. When the control rod moves left and right, the rack on the control rod will mesh with the drive gear, enabling the drive gear to rotate. One end of the limiting rod is connected to the annular groove on the control wheel, and the middle part of the limiting rod is also rotatably connected to the drive frame. Therefore, when the control wheel rotates, the end of the limiting rod will swing up and down. When the end of the limiting rod swings up and down, the limiting plate connected to the end will also move up and down, further causing the locking teeth below the limiting plate to engage or disengage with the drive gear.

[0016] When the control wheel rotates and drives the control lever to move downwards, the insertion rod at the end of the limit rod is located in the outer ring groove. At this time, the limit rod on the control wheel is furthest away from the control lever. The end of the limit rod away from the control wheel moves downwards, driving the limit plate to move downwards. The locking teeth and the drive gear gradually separate and release the lock. At the same time, when the end of the control lever rotates clockwise, it will pull the rack at the other end to move, driving the drive gear to rotate counterclockwise.

[0017] When the control lever on the control wheel moves to the top, the end of the limit lever is located in the inner ring groove. At this time, the limit lever on the control wheel is closest to the control lever. The other end of the limit lever rises up, causing the limit plate to move upward along the guide block, so that the locking teeth under the limit plate mesh with the drive gear, achieving a stable limiting effect.

[0018] This method enables the directional rotation of the drive gear. After rotating to a certain angle, it can be limited so that the rotating blades can collect the dust above. Further rotation can change the position of the rotating blades to continue collecting dust.

[0019] The beneficial effects of this utility model are: it can clean the dust in the dust collection hopper below the bag filter, and the regular cleaning can reduce the backflow of dust from the dust collection hopper into the bag filter. This method can realize the directional rotation of the drive gear, and after rotating to a certain angle, it can be limited so that the rotating blades can collect the dust above. Further rotation can change the position of the rotating blades to continue collecting dust. Attached Figure Description

[0027] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Examples, such as Figure 1 , Figure 2 , Figure 3 As shown, an online pulse jet baghouse dust collector is characterized by: a frame 1, a baghouse dust collector body 2 mounted on the frame 1, a dust collection hopper 21 below the baghouse dust collector body 2, and a dust discharge port 22 below the dust collection hopper 21. A blade assembly 3 is disposed within the dust discharge port 22. A drive unit 4 is mounted on the frame, controlling the rotation of the blade assembly 3. The blade assembly 3 includes a rotating shaft 31 and a plurality of rotating blades 32 radially arranged on the rotating shaft 31. The drive unit 4 drives the rotating shaft 31 to rotate, thereby causing the rotating blades 32 to rotate. This allows for the cleaning of dust in the dust collection hopper 21 below the baghouse dust collector. Timed cleaning reduces the reflow of dust from the dust collection hopper into the baghouse dust collector.

[0029] like Figure 3As shown, the driving component 4 includes a driving rod 41, a driving bevel gear 42, a control bevel gear 43, a driving frame 44, a driving gear 45, and a control component 5. The driving frame 44 is mounted on the frame 1, the driving gear 45 is rotatably connected to the driving frame 44, and the control component 5 controls the rotation of the driving gear 45. The driving rod 41 is coaxially fixedly connected to the driving gear 45, a plurality of driving bevel gears 42 are coaxially fixedly connected to the driving rod 41, and the control bevel gears 43 are coaxially fixedly connected to the rotating shaft 31. The driving bevel gears 42 and the control bevel gears 43 mesh with each other.

[0030] The control component 5 controls the drive gear 45 to rotate, which in turn drives the drive rod 41 to rotate. The drive rod 41 controls the three drive bevel gears 42 mounted on it to rotate. The drive bevel gears 42 further drive the control bevel gear 43 to rotate. The control bevel gear 43 is fixedly connected to the rotating shaft 31. The rotation of the rotating shaft 31 drives the rotating blades 32 to rotate. The six rotating blades 32 are evenly distributed so that a dust collection bin is formed between two adjacent rotating blades 32. The dust inside falls between two rotating blades 32. When rotating, the dust collection bin between the next two blades at the ash discharge port 22 rotates to the ash discharge point. The collected dust in the dust collection bin rotates downward and gradually rotates to the bottom to fall into the bottom for unified recycling.

[0031] like Figure 3 , Figure 4 As shown, the control component 5 includes a drive motor 51, a control wheel 52, and a control lever 53. The drive motor 51 is mounted on the drive frame 44. The control wheel 52 is rotatably connected to the drive frame 44 and coaxially fixedly connected to the output end of the drive motor 51. One end of the control lever 53 is eccentrically rotatably connected to the control wheel 52, and the other end is provided with a rack 531, which meshes with the drive gear 45.

[0032] like Figure 5 As shown, the control wheel 52 has an annular groove 521, which includes an inner annular groove 5211 and an outer annular groove 5212. The inner annular groove 5211 and the outer annular groove 5212 are connected. The distance from the inner annular groove 5211 to the axis of the control hole is less than the distance from the outer annular groove 5212 to the axis of the control hole.

[0033] like Figure 4 , Figure 5 As shown, one end of the control lever 53 is located between the annular groove 521 on the control wheel 52 and the axis of the control wheel 52.

[0034] like Figure 4 , Figure 5As shown, a limiting rod 54 is provided on the drive frame 44. The middle part of the limiting rod 54 is rotatably connected to the drive frame 44. One end of the limiting rod 54 is rotatably provided with an insertion rod 541, which is movably inserted into the annular groove 521. The other end is rotatably provided with a locking block 542, which has a locking groove 543. The control rod 53 is located above the rack 531 and is provided with a locking strip 532, which is slidably locked into the locking groove 543.

[0035] like Figure 5 As shown, a limiting plate 55 is provided at the end of the limiting rod 54 on the other side of the snap-fit ​​block 542. A strip hole 551 is provided at the upper end of the limiting plate 55, and the end of the limiting rod 54 is movably disposed in the strip hole 551.

[0036] like Figure 4 , Figure 5 As shown, a locking tooth 552 is provided below the limiting plate 55. During the rotation of the control wheel 52, the locking tooth 552 on the limiting plate 55 is driven to mesh with the drive gear 45.

[0037] like Figure 5 As shown, a guide block is also fixedly installed on the drive frame 44. The guide block includes an inner guide block 56 and an outer guide block 57. The inner guide block 56 is attached to both sides of the inner wall of the limiting plate 55, and the outer guide block 57 is attached to both sides of the outer wall of the limiting plate 55.

[0038] When the drive gear 45 rotates, the locking teeth 552 on the limiting plate 55 release the drive gear 45 from its restraint. When the drive gear 45 does not rotate, the locking teeth 552 engage and restrain the drive gear 45. When the control wheel 52 rotates, the control rod 53, which is eccentrically connected to the rotating wheel, will move left and right. When the control rod 53 moves left and right, the rack 531 on the control rod 53 will mesh with the drive gear 45, realizing the rotation of the drive gear 45. One end of the limiting rod 54 is connected to the annular groove 521 on the control wheel 52, and the middle part of the limiting rod 54 is also rotatably connected to the drive frame 44. Therefore, when the control wheel 52 rotates, the end of the limiting rod 54 will swing up and down. When the end of the limiting rod 54 swings up and down, the limiting plate 55 connected to the end will also move up and down, further driving the locking teeth 552 below the limiting plate 55 to mesh or disengage from the drive gear 45.

[0039] When the rotation of the control wheel 52 causes the control rod 53 to move downward, the insertion rod 541 at the end of the limit rod 54 is located in the outer ring groove 5212. At this time, the limit rod 54 on the control wheel 52 is furthest from the control rod 53. The end of the limit rod 54 away from the control wheel 52 moves downward, causing the limit plate 55 to move downward. The locking teeth 552 and the drive gear 45 gradually separate and unlock. At the same time, when the end of the control rod 53 rotates clockwise, it will pull the rack 531 at the other end to move, causing the drive gear 45 to rotate counterclockwise.

[0040] When the control lever 53 on the control wheel 52 moves to the top, the end of the limit lever 54, the insertion rod 541, is located in the inner ring groove 5211. At this time, the limit lever 54 on the control wheel 52 is closest to the control lever 53. The other end of the limit lever 54 rises upward, causing the limit plate 55 to move upward along the guide block, so that the locking teeth 552 below the limit plate 55 meshes with the drive gear 45, achieving a stable limiting effect.

[0041] This method enables the directional rotation of the drive gear 45. After rotating to a certain angle, it can be limited so that the rotating blade 32 can collect the dust above. Further rotation can change the position of the rotating blade 32 to continue collecting dust.

[0042] This invention enables the cleaning of dust in the dust collection hopper 21 below the bag filter. Regular cleaning reduces the backflow of dust from the dust collection hopper into the bag filter. This method enables the directional rotation of the drive gear 45. After rotating to a certain angle, the gear can be limited, allowing the rotating blades 32 to collect dust from above. Further rotation changes the position of the rotating blades 32 to continue dust collection.
