Description

Technical Field

[0001] This utility model belongs to the technical field of dust removal devices, specifically relating to an opening and closing device for a dust collector. Background Technology

[0002] Industrial production processes often generate a significant amount of dust-laden flue gas, requiring treatment by dust removal devices to meet emission standards. A patent with publication number CN222718201U discloses an integrated device for purifying and treating exhaust gas from a cremator. This device includes a flue gas treatment component connected to an air-cooling assembly. The flue gas treatment component comprises a support frame, a spark interceptor, a bag filter, and an activated carbon adsorber sequentially positioned on top of the support frame. The spark interceptor's inlet is connected to the air-cooling assembly's outlet via a pipe, and the spark interceptor's outlet is connected to the bag filter's inlet pipe. The activated carbon adsorber's inlet is connected to the bag filter's outlet via a pipe. One end of the exhaust gas emission component is connected to the activated carbon adsorber's outlet to discharge the filtered and dust-treated flue gas. Existing baghouse dust collectors have vertically arranged cages with a cover plate on top of the dust collection chamber. The cover plate is detachable from the dust collection chamber. Each time the cage is replaced, the cover plate needs to be manually opened, resulting in low automation. Furthermore, the cover plate of the existing dust collector is heavy, making manual opening laborious and requiring external tools, which is cumbersome. Therefore, an opening and closing device for dust collectors needs to be designed to overcome these difficulties. Summary of the Invention

[0003] This invention addresses the problems existing in the prior art by designing an opening and closing device for a dust collector. The invention features a lightweight door panel body on the cover of the dust collector housing, and the opening and closing state of the door panel body is synchronously controlled by a single drive component, resulting in a high degree of automation and easier operation.

[0004] The objective of this invention is achieved through the following technical solution: an opening and closing device for a dust collector, comprising a cover plate with several side-by-side placement openings, and a door panel assembly rotatably connected to the side of the cover plate near the placement openings; the door panel assembly includes a transmission rod and a door panel body, with a connecting rod assembly for transmission between each transmission rod; a driving assembly for driving one of the transmission rods to rotate is provided on the edge of the cover plate, and each door panel body rotates synchronously when the driving assembly drives the transmission rod to rotate; a pair of lock holes are provided on the door panel body, and a locking assembly is fixedly installed on the end of the cover plate opposite to the transmission rod; the locking assembly includes a push rod motor and a lock cylinder.

[0005] Preferably, a dust collector housing is fixedly installed below the cover plate, and the dust collector housing is provided with several evenly distributed cages; the cages are detachably connected to the dust collector housing, and a pulse assembly is provided on the side of the dust collector housing. The pulse assembly includes a pulse body and several evenly distributed hollow pipes; one end of the hollow pipe is connected to the pulse body, and the other end of the hollow pipe extends and is installed on the inner wall of the dust collector housing; the hollow pipes are oriented towards each cage, and the placement opening is oriented towards the hollow pipe.

[0006] The cage frame is installed inside the dust collector chamber, and a filter bag is placed over the outer layer of the cage frame. Large dust particles in the flue gas are adsorbed onto the outer layer of the filter bag, while small dust particles and flue gas pass through the filter bag and are discharged from the top opening of the dust collector chamber. Electromagnetic pulses are emitted to the hollow duct via the pulse jet unit, causing the dust particles to be impacted and automatically fall to the bottom of the dust collector chamber. After prolonged use, the filter bags need to be replaced. This requires opening the main door panel to remove the cage frame and replace the filter bags.

[0007] Preferably, the cover plate is provided with a plurality of paired mounting bases, and the transmission rod is rotatably connected to the mounting bases; the edge of the cover plate is also provided with a plurality of support bases facing the mounting bases, one end of the transmission rod is inserted into the mounting base, and the other end of the transmission rod passes out from the mounting base and is connected to the connecting rod assembly.

[0008] Preferably, the transmission rod is rotatably connected to the mounting base, and a door panel body is fixedly mounted on the transmission rod. The transmission rod and the door panel body rotate synchronously. The transmission rod is provided with a detachable first retaining ring, and each first retaining ring is fitted against the outer wall of each mounting base. The first retaining ring is installed in a slot in the transmission rod.

[0009] The drive rod is rotatably connected to the mounting base, allowing it to rotate relative to the cover plate. This rotation of the drive rod drives the door panel to rotate synchronously. The support base ensures better concentricity of the drive rod, making its rotation more stable. A first retaining ring axially limits the drive rod, preventing axial movement relative to the mounting base.

[0010] Preferably, the linkage assembly includes a main connecting rod and a plurality of intermediate connecting rods arranged side by side and evenly distributed; the intermediate connecting rods are fixedly connected to the ends of the transmission rods and the two rotate synchronously; the main connecting rod is hinged to each of the intermediate connecting rods, and when the driving assembly drives one of the transmission rods to rotate, the main connecting rod drives each of the intermediate connecting rods to rotate synchronously.

[0011] Preferably, a transmission pin is provided between the main connecting rod and the intermediate connecting rod to hinge the two; the transmission pin is inserted between the main connecting rod and the intermediate connecting rod, and the protrusion of the transmission pin is fitted with the main connecting rod; a second retaining ring is provided on the transmission pin and is set in the groove of the transmission pin; the second retaining ring is fitted with the end face of the intermediate connecting rod.

[0012] When the drive assembly is working, it drives one of the transmission rods to rotate. The rotation of the transmission rod drives the intermediate connecting rod to rotate synchronously. The intermediate connecting rod is hinged to the main connecting rod. The rotation of the intermediate connecting rod causes the main connecting rod to rotate offset, and the rotation of the main connecting rod causes the remaining intermediate connecting rods to rotate. After the intermediate connecting rods rotate, they drive the adjacent transmission rods to rotate, thus allowing each door panel to rotate synchronously. This improves the synchronization of door panel opening and closing, facilitating the unified replacement of the cloth bags on the cage frame. The use of a transmission pin and a second retaining ring facilitates the hinged connection between the main connecting rod and the intermediate connecting rods.

[0013] Preferably, the drive assembly includes a drive motor, a first gear, and a second gear; the first gear is fixedly mounted on the motor shaft of the drive motor, and the second gear is fixedly mounted on one of the transmission rods, the first gear and the second gear meshing with each other; when the drive motor is working, the transmission rod drives the door panel body to rotate; the cover plate is provided with a pair of mounting bases, and the edge of the cover plate is also provided with a support base, and the transmission rod is rotatably connected to the mounting base and the support base.

[0014] Preferably, the transmission rod is provided with a first retaining ring near the mounting base, and the first retaining ring is fitted to the mounting base; a limiting sleeve is also fitted on the transmission rod, and the limiting sleeve is fitted to the support base; the second gear is fitted to the end face of the limiting sleeve; and a third retaining ring is also provided on the transmission rod, and the third retaining ring is fitted to the second gear.

[0015] Preferably, a motor bracket is also fixedly installed on the cover plate, and the motor shaft of the drive motor is rotatably connected to the motor bracket; a rotating block is fixedly installed on the motor shaft of the drive motor, and the rotating block is disposed between the first gear and the motor bracket; the rotating block is provided with a mounting groove, and a magnet is provided in the mounting groove; two circumferentially distributed Hall sensors are provided on the end face of the motor bracket facing the rotating block, and the included angle of the two Hall sensors is the same as the rotation angle of the door panel body.

[0016] The drive motor rotates the first gear, which in turn rotates the second gear, which in turn rotates the transmission rod. This operation of the drive motor controls the rotation of the door panel. When a magnet approaches the Hall sensor, the Hall sensor sends an electrical signal to the control panel, which then sends a working command to the drive motor. The control panel is electrically connected to both the drive motor and the Hall sensor. By using the Hall sensor, the opening and closing angle of the door panel can be easily controlled. The control panel is a standard control circuit board and is not shown in the accompanying drawings. The second gear is axially limited by a limit sleeve and a third retaining ring.

[0017] Preferably, the locking assembly further includes a positioning bracket, which is fixedly mounted on the cover plate; a push rod motor is fixedly mounted on the positioning bracket, and a lock cylinder is fixedly mounted on the telescopic push rod of the push rod motor, with the lock cylinder facing the lock hole; the outer contour of the lock cylinder is adapted to the outer contour of the lock hole.

[0018] When the door panel is closed, the lock cylinder extends into the keyhole, making the closed state of the door panel more stable and reliable. During dust removal, the lock cylinder remains inside the keyhole, and the door panel cannot open automatically. When it is necessary to open the door panel, the push rod motor controls the lock cylinder to retract, so that the door panel loses its limit, and the drive assembly can control the door panel to rotate.

[0019] Compared with existing technologies, this utility model has the following advantages: 1. Each door panel assembly corresponds to each row of cages, which facilitates the unified replacement of cloth bags on the same row of cages. The lightweight design of the door panel body allows for faster opening and closing. 2. The drive motor drives the transmission rod on the door panel assembly to rotate. The transmission rods are interconnected through a linkage assembly, so all door panels can open or close simultaneously when the drive motor is working, resulting in better synchronization and facilitating unified cloth bag replacement. 3. The locking assembly locks the door panel body in the closed state, preventing accidental opening and making the dust removal process safer and more reliable. Attached Figure Description

A detachably connected second retaining ring 44 is provided on the transmission pin 43, and the second retaining ring 44 is located in a slot of the transmission pin 43. The second retaining ring 44 is fitted against the end face of the intermediate connecting rod 42.

[0033] The drive assembly 5 includes a drive motor 51, a first gear 52, and a second gear 53. The first gear 52 is fixedly mounted on the motor shaft of the drive motor 51, and the second gear 53 is fixedly mounted on one of the transmission rods 31. The first gear 52 and the second gear 53 mesh with each other. When the drive motor 51 is working, the transmission rod 31 drives the door panel body 32 to rotate. The cover plate 1 is provided with a pair of mounting bases 10, and the edge of the cover plate 1 is also provided with a support base 11. The transmission rods 31 are rotatably connected to the mounting bases 10 and the support bases 11.

[0034] The specific operation process of this embodiment is as follows: The cage frame 8 is installed inside the dust collector 7, and a cloth bag is fitted over the outer layer of the cage frame 8. Large dust particles in the flue gas are adsorbed onto the outer layer of the cloth bag, while small dust particles and flue gas pass through the cloth bag and are discharged from the top opening of the dust collector 7. An electromagnetic pulse is emitted to the hollow pipe 92 via the pulse generator 91, causing the dust to be impacted and automatically fall to the bottom of the dust collector 7.

By setting the Hall sensor 58, the opening and closing angle of the door panel body 32 can be easily controlled. The control panel is a standard control circuit board and is not shown in the accompanying drawings. When the drive assembly 5 is working, it drives one of the transmission rods 31 to rotate. When the transmission rod 31 rotates, it drives the intermediate connecting rod 42 to rotate synchronously. The intermediate connecting rod 42 is hinged to the main connecting rod 41. When the intermediate connecting rod 42 rotates, it drives the main connecting rod 41 to rotate offset. When the main connecting rod 41 rotates, it drives the other remaining intermediate connecting rods 42 to rotate. After the intermediate connecting rods 42 rotate, they drive the transmission rods 31 adjacent to them to rotate. In this way, each door panel body 32 can rotate synchronously. The opening and closing of the door panel body 32 has better synchronization, which facilitates the uniform replacement of the cloth bags on the cage frame.
