Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a filter bag dust collector. Background Art

[0002] A bag dust collector is a dry dust filtering device. It is suitable for collecting fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt. The fiber fabric is used to filter the dust-containing gas. When the dust-containing gas enters the bag dust collector, dust with large particles and high specific gravity settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, and the gas is purified.

[0003] A Chinese patent discloses a bag dust collector with the authorization announcement number CN217139640U. This patented technology not only facilitates people to disassemble the dust collection box from the main body for discharging the dust collected after dust removal, but also can close and seal the rectangular insertion sleeve during the disassembly process to prevent the phenomenon that dust is easily scattered everywhere during subsequent disassembly, which may cause harm to human health.

[0004] In view of the above and related existing technologies, the inventor believes that the following defects often exist: After long-term use of the existing bag dust collector, the filter bag for filtering dust will inevitably be clogged with dust or worn and damaged, affecting the dust filtering efficiency of the air. However, the bag is not convenient to disassemble, and it is extremely cumbersome for the staff to clean or replace the bag, which greatly reduces the air purification effect of the dust collector after long-term use. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is: There is a disadvantage in the prior art that the filter bag is not convenient to disassemble, replace or clean. For this reason, we propose a filter bag dust collector.

[0006] In order to achieve the above object, the present application adopts the following technical solution: A filter bag dust collector includes a dust collector main body. Doors are installed on both sides of the top of the dust collector main body. A bracket is installed inside the dust collector main body. The top of the bracket abuts against a first clamping plate. The top of the first clamping plate abuts against a plurality of annular plates. The bottom of the annular plate is fixedly connected to a bag body. The top of the annular plate abuts against a second clamping plate. Both ends of the top of the second clamping plate are fixedly connected with handles. The periphery of the top of the second clamping plate is fixedly connected with rotating shafts. A limiting rod is rotatably connected to the surface of the rotating shaft. The bottom of the limiting rod is fixedly connected with an L-shaped plate. The bottom of the L-shaped plate abuts against the bottom of the first clamping plate.

[0007] Preferably, a first spring is fixedly connected to one side of the limiting rod, and an extension block is fixedly connected to the end of the first spring away from the limiting rod. The bottom of the extension block is fixedly connected to the top of the second clamping plate.

[0008] Preferably, a chute is formed inside the limiting rod, and a sliding rod is slidably connected to the inner wall of the chute. One end of the sliding rod is fixedly connected to the extension block.

[0009] Preferably, a nut block is installed on the top of the limiting rod, and a threaded rod is threadedly connected to the inside of the nut block. The surface of the threaded rod abuts against the surface of the sliding rod.

[0010] Preferably, the sliding rod is disposed inside the first spring, and the inner wall of the first spring is slidably connected to the surface of the sliding rod.

[0011] Preferably, insertion rods are fixedly connected to the four circumferences of the top of the bracket, and limiting grooves for cooperating with the insertion rods are formed in the circumferences of the first clamping plate and the second clamping plate.

[0012] Preferably, a rounded corner is formed at the top of the insertion rod.

[0013] The technical effects and advantages of the present utility model:

[0014] In the present utility model, the staff passes the cloth bag body through the hole of the first clamping plate so that the circular ring plate is placed on the top of the first clamping plate, then combines the second clamping plate with the first clamping plate so that the second clamping plate and the first clamping plate clamp the circular ring plate, and then rotates the limiting rod to drive the L-shaped plate to abut against the bottom of the first clamping plate, so that the limiting rod and the L-shaped plate form a clamp on the second clamping plate and the first clamping plate, fixing the positions of the circular ring plate and the cloth bag body. Then, the first clamping plate is placed on the top of the bracket, and the cloth bag body is installed inside the dust collector body, so as to facilitate the staff to disassemble and clean the dust attached to the cloth bag body during long-term use or replace the cloth bag body, thereby improving the air filtration effect of the device.

Detailed implementation manners

[0023] Now, with reference to the attached drawings and preferred embodiments, the present utility model will be further described in detail. These drawings are all simplified schematic diagrams, only showing the basic structure of the present utility model in a schematic way, so they only show the components related to the present utility model.

[0024] Refer to Figure 1 - Figure 7 As shown, the present utility model provides a technical solution: a filter bag dust collector, including a dust collector body 1. On both sides of the top of the dust collector body 1, door panels 2 are installed. Inside the dust collector body 1, a bracket 3 is installed. The top of the bracket 3 abuts against a first clamping plate 4. On the top of the first clamping plate 4, several ring plates 5 abut. The bottom of the ring plate 5 is fixedly connected to a bag body 6. On the top of the ring plate 5, a second clamping plate 7 abuts. At both ends of the top of the second clamping plate 7, handles 8 are fixedly connected. Around the top of the second clamping plate 7, rotating shafts 9 are fixedly connected. The surface of the rotating shaft 9 is rotatably connected to a limiting rod 10. The bottom of the limiting rod 10 is fixedly connected to an L-shaped plate 11. The bottom of the L-shaped plate 11 abuts against the bottom of the first clamping plate 4. By the staff passing the bag body 6 through the holes of the first clamping plate 4 so that the ring plate 5 is placed on the top of the first clamping plate 4, then combining the second clamping plate 7 with the first clamping plate 4 so that the second clamping plate 7 and the first clamping plate 4 clamp the ring plate 5, and then rotating the limiting rod 10 to drive the L-shaped plate 11 to abut against the bottom of the first clamping plate 4, so that the limiting rod 10 and the L-shaped plate 11 form a clamping of the second clamping plate 7 and the first clamping plate 4, fixing the positions of the ring plate 5 and the bag body 6. Then placing the first clamping plate 4 on the top of the bracket 3 and installing the bag body 6 inside the dust collector body 1, which is convenient for the staff to disassemble and clean the dust attached to the bag body 6 during long-term use or replace the bag body 6, thereby improving the air filtration effect of the device.

[0025] Refer to Figure 4 And Figure 5As shown in the figure, in this embodiment: One side of the limit rod 10 is fixedly connected with a first spring 12. The end of the first spring 12 away from the limit rod 10 is fixedly connected with an extension block 13. The bottom of the extension block 13 is fixedly connected with the top of the second clamping plate 7. By the pulling of the first spring 12 on the limit rod 10, the initial position of the limit rod 10 is restricted. When the limit rod 10 rotates and drives the L-shaped plate 11 to move away from the bottom of the first clamping plate 4 to release the clamping of the first clamping plate 4 and the second clamping plate 7 by the limit rod 10 and the L-shaped plate 11, the first spring 12 will be pulled by the limit rod 10 to store energy. When the staff loosens the limit rod 10, the force generated by the release of the first spring 12 will pull the limit rod 10 to rebound to reset the position of the limit rod 10, so that the L-shaped plate 11 and the limit rod 10 are always placed at the clamping position of the first clamping plate 4 and the second clamping plate 7, thereby preventing the displacement of the limit rod 10 after the mechanism is installed in the dust collector body 1.

[0026] Refer to Figure 4 And Figure 5 As shown in the figure, in this embodiment: A chute 14 is opened inside the limit rod 10. A sliding rod 15 is slidably connected to the inner wall of the chute 14. One end of the sliding rod 15 is fixedly connected with the extension block 13. When the first spring 12 pulls the limit rod 10 to move, through the sliding connection between the chute 14 and the sliding rod 15, the movement track of the limit rod 10 is restricted, preventing the limit rod 10 from tilting during movement and causing unstable clamping of the first clamping plate 4 and the second clamping plate 7 by the limit rod 10 and the L-shaped plate 11, thereby improving the stability of the component operation.

[0027] Refer to Figure 4 And Figure 5 As shown in the figure, in this embodiment: A nut block 16 is installed on the top of the limit rod 10. A threaded rod 17 is threadedly connected to the inside of the nut block 16. The surface of the threaded rod 17 abuts against the surface of the sliding rod 15. When the staff screws the threaded rod 17 downward into the chute 14 through the nut block 16 so that the threaded rod 17 is placed on the surface of the sliding rod 15 and abuts against the sliding rod 15, the position of the limit rod 10 is restricted, so that the limit rod 10 can no longer rotate, preventing the displacement of the limit rod 10 and the L-shaped plate 11 when the device is vibrated and releasing the clamping of the first clamping plate 4 and the second clamping plate 7.

[0028] Refer to Figure 4 And Figure 5 As shown in the figure, in this embodiment: The sliding rod 15 is placed inside the first spring 12. The inner wall of the first spring 12 is slidably connected to the surface of the sliding rod 15. Through the sliding connection between the sliding rod 15 and the first spring 12, the first spring 12 can move closely along the surface of the sliding rod 15, restricting the movement track of the first spring 12 and preventing the first spring 12 from curling and winding during operation, which affects the normal operation of the component.

[0029] Refer to Figure 6 AndFigure 7 As shown, in this implementation: Plug rods 18 are fixedly connected to the periphery of the top of the bracket 3. Limiting grooves 19 that cooperate with the plug rods 18 are provided around the first clamping plate 4 and the second clamping plate 7. Through the arrangement of the plug rods 18, the first clamping plate 4 and the second clamping plate 7 can be inserted into the surface of the plug rods 18 through the limiting grooves 19 to limit the positions of the first clamping plate 4 and the second clamping plate 7, preventing the second clamping plate 7 from sliding freely on the surface of the circular ring plate 5 when the first clamping plate 4 and the second clamping plate 7 clamp the circular ring plate 5, resulting in the detachment of the components.

[0030] Refer to Figure 6 And Figure 7 As shown, in this implementation: A rounded corner 20 is provided at the top of the plug rod 18. Through the rounded corner 20 provided at the top of the plug rod 18, the top of the plug rod 18 has a curvature and is more rounded, reducing the friction when the top of the plug rod 18 contacts the limiting groove 19, and making it more convenient for the staff to insert the plug rod 18 into the limiting groove 19.

[0031] Working principle: The staff passes the cloth bag body 6 through the hole of the first clamping plate 4 so that the circular ring plate 5 is placed on the top of the first clamping plate 4, then combines the second clamping plate 7 with the first clamping plate 4 so that the second clamping plate 7 and the first clamping plate 4 clamp the circular ring plate 5, and then rotates the limiting rod 10 to drive the L-shaped plate 11 to abut against the bottom of the first clamping plate 4, so that the limiting rod 10 and the L-shaped plate 11 form a clamping of the second clamping plate 7 and the first clamping plate 4, fixing the positions of the circular ring plate 5 and the cloth bag body 6. Then, place the first clamping plate 4 on the top of the bracket 3 and install the cloth bag body 6 inside the dust collector body 1, which is convenient for the staff to disassemble and clean the dust attached to the cloth bag body 6 during long-term use or replace the cloth bag body 6, thereby improving the air filtration effect of the device. Through the pulling of the first spring 12 on the limiting rod 10, the initial position of the limiting rod 10 is restricted. When the limiting rod 10 rotates and drives the L-shaped plate 11 to move away from the bottom of the first clamping plate 4 to release the clamping of the limiting rod 10 and the L-shaped plate 11 on the first clamping plate 4 and the second clamping plate 7, the first spring 12 will be pulled by the limiting rod 10 to store energy. When the staff loosens the limiting rod 10, the first spring 12 will release the generated force to pull the limiting rod 10 back to reset the position of the limiting rod 10, so that the L-shaped plate 11 and the limiting rod 10 are always in the clamping position of the first clamping plate 4 and the second clamping plate 7, thereby preventing the displacement of the limiting rod 10 after the mechanism is installed in the dust collector body 1. When the first spring 12 pulls the limiting rod 10 to move, through the sliding connection of the sliding groove 14 and the sliding rod 15, the moving track of the limiting rod 10 is restricted, preventing the limiting rod 10 from tilting when moving, which causes the clamping of the limiting rod 10 and the L-shaped plate 11 on the first clamping plate 4 and the second clamping plate 7 to be unstable, thereby improving the stability of the component operation. When the staff screws the threaded rod 17 downward into the sliding groove 14 through the nut block 16 so that the threaded rod 17 is placed on the surface of the sliding rod 15 and abuts against the sliding rod 15, the position of the limiting rod 10 is restricted, so that the limiting rod 10 can no longer rotate, preventing the displacement of the limiting rod 10 and the L-shaped plate 11 to release the clamping of the first clamping plate 4 and the second clamping plate 7 when the device is vibrated. Through the sliding connection of the sliding rod 15 and the first spring 12, the first spring 12 can move closely along the surface of the sliding rod 15, restricting the moving track of the first spring 12, preventing the first spring 12 from curling and winding during operation, which affects the normal operation of the component. Through the setting of the insertion rod 18, the first clamping plate 4 and the second clamping plate 7 can be inserted into the surface of the insertion rod 18 through the limiting groove 19 to restrict the positions of the first clamping plate 4 and the second clamping plate 7, preventing the second clamping plate 7 from sliding arbitrarily on the surface of the circular ring plate 5 when the first clamping plate 4 and the second clamping plate 7 clamp the circular ring plate 5, resulting in the disengagement of the component. Through the rounded corner 20 opened at the top of the insertion rod 18, the top of the insertion rod 18 has a radian and is more rounded, reducing the friction when the top of the insertion rod 18 contacts the limiting groove 19, which is more conducive to the staff inserting the insertion rod 18 into the limiting groove 19.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
