Description

Technical Field

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

[0002] A bag filter is a dry dust filtration device suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-woven felt, and utilizes the filtering effect of the fiber fabric to filter the dust-laden gas. When the dust-laden gas enters the bag filter, the large particles with a high specific gravity settle due to gravity and fall into the ash hopper. The gas containing finer dust is retained when passing through the filter material, thus purifying the gas. In a bag filter, the filter bag is an indispensable and important component of the bag filter. The cost of replacing the filter bag is the main maintenance cost of the bag filter dust collector, and the filter bag frame plays the role of supporting the filter bag and is a key component.

[0003] Publication number CN215310929U discloses a patent for a cartridge filter bag for a dust collector that is easily removable and assembled. The patent discloses a panel with multiple filter bag mounting holes formed therein, wherein filter bags are disposed in the filter bag mounting holes. The filter bag comprises a bag body that performs a filtering function, the top opening of the bag body being folded outwardly and wrapped with a rubber ring with a T-shaped cross section. A sleeve is provided on the outer side of the vertical portion of the rubber ring and fixed to the filter bag mounting hole. A pressure plate with a T-shaped cross section is provided on top of the rubber ring. The vertical portion of the pressure plate is connected to the filter bag support frame below, and the horizontal portion of the pressure plate abuts the rubber ring. Side panels are connected to both sides of the pressure plate, each of which has a U-shaped opening formed therein. Studs are disposed in the U-shaped opening. The lower ends of the studs are hinged to the panel. A butterfly nut is threadedly connected to the stud and abuts the upper surface of the side panels. The utility model has a simple structure and is relatively easy to assemble and disassemble, making it easy to clean, maintain, and replace the filter bag, thereby improving the maintenance and replacement efficiency of the filter bag.

[0004] The above-mentioned existing filter bag installation structure uses bolts to fix and clamp it, which is cumbersome to disassemble and assemble, and is not convenient for maintenance. Moreover, when the filter bag is in use, it cannot automatically clean the dust attached to the inner wall of the filter bag, affecting the filtering efficiency of the filter bag.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0024] like Figures 1 to 4 As shown, the utility model is a dust collector filter bag disassembly and assembly structure, comprising: a flower plate 1, a filter bag 2 mounted on the flower plate 1, a filter bag support frame 3 to prevent the filter bag 2 from deforming, and an installation component 4 to limit the filter bag support frame 3;

[0025] The mounting assembly 4 includes: a limiting groove 401 provided on the side wall of the filter bag support frame 3, a limiting pin 402 inserted in the limiting groove 401 to limit the filter bag support frame 3, a support block is provided on the surface of the limiting pin 402, and the bottom of the support block is fixedly mounted on the surface of the flower plate 1, through the setting of the support block, the movement of the limiting pin 402 is guided, a connecting ring 403 fixedly mounted on the limiting pin 402, and a first spring 404 sleeved on the limiting pin 402; one end of the first spring 404 is fixedly connected to the surface of the connecting ring 403, and the other end of the first spring 404 is fixedly connected to the surface of the support block. After the filter bag support frame 3 is installed in place, the first spring 404 elastically resets and pushes one end of the limiting pin 402 to be inserted into the limiting groove 401 for limiting.

[0026] When installing the filter bag 2, first install the filter bag 2 on the flower plate 1, then insert the filter bag support frame 3 into the interior of the filter bag 2, pull the limit pin 402 to move to a position away from the filter bag support frame 3, and after the filter bag support frame 3 is installed in place, release the limit pin 402, so that the first spring 404 elastically resets after being stressed, pushing the connecting ring 403 to move, so that the connecting ring 403 drives one end of the limit pin 402 to be inserted into the limit groove 401 on the side wall of the filter bag support frame 3, completing the rapid installation of the filter bag 2 and the filter bag support frame 3.

[0027] A support ring 301 is fixedly installed in the middle of the filter bag support frame 3, and a dust cleaning component 5 is provided on the support ring 301.

[0028] The dust cleaning component 5 includes: a rotating fan blade 501 rotatably mounted on the filter bag support frame 3, an extrusion block 502 fixedly mounted on the rotating fan blade 501, a connecting rod 503 fixedly mounted on the support ring 301, and a slider 504 slidably mounted on the connecting rod 503. The top of the slider 504 is set as an inclined surface, and the surface of the extrusion block 502 is set as an arc that matches the inclined surface of the top of the slider 504. When the rotating fan blade 501 drives the extrusion block 502 on the blade to rotate, the extrusion block 502 will intermittently squeeze the inclined surface of the top of the slider 504, pushing the slider 504 to move. The interference between the inclined surface of the top of the slider 504 and the arc setting of the surface of the extrusion block 502 is reduced. A second spring 505 is mounted on the connecting rod 503 to drive the slider 504 to return to its original position. One end of the second spring 505 is fixedly connected to the surface of the slider 504, and the other end of the second spring 505 is fixedly connected to the inner wall of the support ring 301 and the impact rod 506 fixedly mounted at the bottom of the slider 504.

[0029] When the dust collector exhausts dust through the filter bag, the exhausted airflow acts on the rotating fan blades 501 inside the filter bag support frame 3, thereby driving the rotating fan blades 501 to rotate, causing the extrusion block 502 on the rotating fan blades 501 to rotate, and intermittently squeezing the inclined surface of the top of the slider 504 slidably installed on the surface of the connecting rod 503, thereby pushing the impact rod 506 at the bottom of the slider 504 to hit one side of the inner wall of the filter bag 2, and when the slider 504 is squeezed, the second spring 505 is forced to contract. When the slider 504 is released from the squeezing block 502, the second spring 505 elastically returns to its original position after being stressed, pushing the slider 504 to move, causing the impact rod 506 at the bottom of the slider 504 to hit the other side of the inner wall of the filter bag 2 again. By repeatedly hitting the inner wall of the filter bag 2, the dust attached to the inner wall of the filter bag 2 is shaken off, further improving the filtration efficiency.

[0030] Working principle: When installing the filter bag of the dust collector, first install the filter bag 2 on the flower plate 1 of the dust collector, then insert the filter bag support frame 3 into the interior of the filter bag 2, pull the limit pin 402 to move to a position away from the filter bag support frame 3, and after the filter bag support frame 3 is installed in place, release the limit pin 402, so that the first spring 404 elastically resets after being stressed, pushing the connecting ring 403 to move, so that the connecting ring 403 drives one end of the limit pin 402 to be inserted into the limit groove 401 on the side wall of the filter bag support frame 3, completing the rapid installation of the filter bag 2 and the filter bag support frame 3. When the dust collector exhausts dust through the filter bag, the exhausted airflow acts on the rotating fan blades 501 inside the filter bag support frame 3. This drives the rotating fan blade 501 to rotate, causing the extrusion block 502 on the rotating fan blade 501 to rotate, and intermittently squeezes the inclined surface of the top of the slider 504 slidably installed on the surface of the connecting rod 503, thereby pushing the impact rod 506 at the bottom of the slider 504 to hit one side of the inner wall of the filter bag 2, and when the slider 504 is squeezed, the second spring 505 is forced to contract. When the slider 504 is released from the extrusion block 502, the second spring 505 elastically returns to its original position after being stressed, pushing the slider 504 to move, causing the impact rod 506 at the bottom of the slider 504 to hit the other side of the inner wall of the filter bag 2 again. By repeatedly hitting the inner wall of the filter bag 2, the dust attached to the inner wall of the filter bag 2 is shaken off, reducing the clogging of the filter holes.
