Description

Technical Field

[0001] This utility model relates to a bag dust collector, specifically an air-vibration cleaning bag dust collector, belonging to the field of dust collector technology. Background Technology

[0002] The air-vibration baghouse dust collector is a baghouse dust collection device that uses the principle of air vibration for dust removal. Its working principle is that compressed air with a pressure of 0.5~0.7MPa is injected into the dust collector box by controlling the pulse valve. The compressed air is rapidly expanded in the box and rushes into the filter bags, causing them to deform and shake violently. With the action of the reverse airflow, the dust on the outside of the filter bags is removed and falls into the ash hopper. After a period of use, the filter bags inside the air-vibration baghouse dust collector need to be replaced. Before replacing the filter bags, the top cover plate needs to be opened first.

[0003] However, the top cover of traditional air-vibrating bag dust collectors is mostly installed with multiple bolts. Therefore, each time the cover is removed and installed, the bolts need to be turned repeatedly. This process wastes time and energy, making it inconvenient to quickly remove and install the cover. As a result, it increases the time for bag replacement and reduces the efficiency of bag replacement. Utility Model Content

[0004] The purpose of this invention is to provide an air-vibration cleaning bag dust collector to solve the above problems. It enables quick disassembly and assembly of the cover plate, avoiding the need to repeatedly twist the bolts to disassemble and assemble the cover plate, thereby shortening the bag replacement time and improving the bag replacement efficiency.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: an air-vibration cleaning bag dust collector includes a bag dust collector body. Two connecting shafts are rotatably connected to the top ends of both sides of the bag dust collector body. A cover plate is fixedly connected to the connecting shaft. The bag dust collector body is provided with an opening and closing structure, which includes an electric push rod and a crossbar. Two electric push rods are installed on the bag dust collector body, and the top ends of the two electric push rods are fixedly connected to the same crossbar. Two connecting plates are fixedly connected to the bottom end of the crossbar. A first guide groove is provided on the connecting plate. Two guide seats are fixedly connected to the bag dust collector body. A sliding rod is slidably connected to the guide seat. A first guide shaft is fixedly connected to the sliding rod. The first guide shaft extends into the interior of an adjacent first guide groove and is slidably connected to the connecting plate. A rack is fixedly connected to the end of the sliding rod. Two gears are fixedly connected to both ends of the connecting shaft. The gears mesh with adjacent racks. A pressing structure is provided on the crossbar. Multiple cloth bags are installed inside the bag dust collector body.

[0006] Preferably, the upper half of the first guide groove is vertically arranged, and the lower half of the first guide groove is inclined.

[0007] Preferably, the vertical cross-section of the cover plate near the connecting shaft is L-shaped, the two cover plates are symmetrically distributed about the middle of the bag dust collector body, and the bottom end of the cover plate abuts against the bag dust collector body.

[0008] Preferably, a sealing gasket is engaged on the side of the cover plate near the body of the bag filter, and the bottom end of the sealing gasket abuts against the body of the bag filter.

[0009] Preferably, the pressing structure includes a connecting cylinder and a rotating shaft. Two connecting cylinders are fixedly connected to the body of the bag dust collector. A rotating shaft is movably connected inside the connecting cylinder. The rotating shaft is rotatably connected to a crossbar. A stop block is fixedly connected to the rotating shaft. The bottom end of the stop block abuts against the top end of the cover plate.

[0010] Preferably, a second guide shaft is fixedly connected to the connecting cylinder, and a second guide groove is provided on the rotating shaft. One end of the second guide shaft extends into the interior of the second guide groove and is slidably connected to the rotating shaft.

[0011] Preferably, the upper and lower parts of the second guide groove are both vertically arranged, and the middle part of the second guide groove has a spiral structure.

[0012] Preferably, a high-pressure air tank is installed on the bag filter body, and an air blowing pipe is fixedly connected to one end of the high-pressure air tank. The air blowing pipe is fixedly connected to the bag filter body, and one end of the air blowing pipe extends into the interior of the bag filter body. A pulse valve is installed on the air blowing pipe.

[0013] Preferably, the bag filter body is fixedly connected to four support legs, and the inner side of the filter bag is provided with a support frame.

[0014] Preferably, an air inlet pipe is fixedly connected to one side of the bag filter body, and an air outlet pipe is fixedly connected to the other side of the bag filter body.

[0015] The beneficial effects of this utility model are as follows: When it is necessary to open the cover to replace the cloth bag, two electric push rods can be activated simultaneously. The extension of the electric push rods will drive the crossbar to move, the crossbar will drive the two connecting plates to move, the connecting plates will drive the first guide groove to move, and at the same time the first guide groove moves, the first guide shaft will move inside the first guide groove. When the first guide shaft moves at the inclined position at the lower part of the first guide groove, the slide rod will slide on the guide seat. The movement of the slide rod will drive the two racks to move, and the racks will drive the gears to rotate. Since one rack is located at the top of one gear and the other rack is located at the bottom of another gear, the unidirectional movement of the two racks will cause the two gears to rotate in opposite directions. The rotation of the gears will drive... The connecting shaft rotates, causing the cover plate to move away from the baghouse dust collector body. After the cover plate rotates 180 degrees, the electric push rod stops extending. At this point, the cover plate will no longer block the filter bag, and the filter bag can then be replaced. Therefore, by simultaneously activating two electric push rods, both cover plates can be opened quickly, avoiding the need to use a wrench to tighten multiple bolts to disassemble and assemble the cover plates. This shortens the cover plate opening time, facilitates quick filter bag replacement, and improves operational convenience. Furthermore, when the cover plate is placed on top of the baghouse dust collector body, the pressure structure applies low pressure to its end, thus ensuring a tight seal between the cover plate and the baghouse dust collector body, thereby improving the sealing performance between the cover plate and the baghouse dust collector body.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an air-vibration cleaning baghouse dust collector includes a baghouse dust collector body 1. Two connecting shafts 2 are rotatably connected to the top of both sides of the baghouse dust collector body 1. Cover plates 3 are fixedly connected to the connecting shafts 2. The vertical cross-section of the cover plate 3 near the connecting shaft 2 is L-shaped. The two cover plates 3 are symmetrically distributed about the middle of the baghouse dust collector body 1. The bottom end of the cover plate 3 abuts against the baghouse dust collector body 1. The baghouse dust collector body 1 is provided with an opening and closing structure 4, which includes an electric push rod 401 and a crossbar 402. Two electric push rods 401 are installed on the baghouse dust collector body 1. The top ends of the two electric push rods 401 are fixedly connected to the same crossbar 402. The bottom end of the crossbar 402... Two connecting plates 403 are fixedly connected, and the connecting plates 403 are provided with a first guide groove 404. Two guide seats 407 are fixedly connected to the bag dust collector body 1. A slide rod 406 is slidably connected to the guide seat 407. A first guide shaft 405 is fixedly connected to the slide rod 406. The first guide shaft 405 extends into the interior of the adjacent first guide groove 404 and is slidably connected to the connecting plates 403. A rack 408 is fixedly connected to the end of the slide rod 406. Two gears 409 are fixedly connected to both ends of the connecting shaft 2. The gears 409 mesh with the adjacent racks 408. A pressing structure 5 is provided on the crossbar 402. Multiple cloth bags 10 are installed inside the bag dust collector body 1.

[0023] As a technical optimization solution of this utility model, such as Figure 2 As shown, the upper half of the first guide groove 404 is vertically arranged, so when the first guide shaft 405 moves in the upper half of the first guide groove 404, the slide rod 406 will not move, thereby avoiding collision between the slide rod 406 and the abutment block 503. The lower half of the first guide groove 404 is inclined, so when the first guide shaft 405 moves in the lower half of the first guide groove 404, the slide rod 406 will slide, thereby automatically opening the two cover plates 3.

[0024] As a technical optimization solution of this utility model, therefore Figure 3 and Figure 4As shown, a sealing gasket 6 is engaged on the side of the cover plate 3 near the bag dust collector body 1, which can improve the sealing between the cover plate 3 and the bag dust collector body 1.

[0025] As a technical optimization solution of this utility model, such as Figure 2 , Figure 3 and Figure 4 As shown, the pressing structure 5 includes a connecting cylinder 501 and a rotating shaft 502. Two connecting cylinders 501 are fixedly connected to the bag dust collector body 1. The rotating shaft 502 is movably connected inside the connecting cylinder 501. The rotating shaft 502 is rotatably connected to the crossbar 402. A stop block 503 is fixedly connected to the rotating shaft 502. Therefore, when the cover plate 3 is closed, the stop block 503 can press against the cover plate 3 to press against the bag dust collector body 1, thereby improving the sealing between the cover plate 3 and the bag dust collector body 1.

[0026] As a technical optimization solution of this utility model, such as Figure 4 As shown, a second guide shaft 504 is fixedly connected to the connecting cylinder 501, and a second guide groove 505 is provided on the rotating shaft 502. The upper and lower parts of the second guide groove 505 are both vertically arranged, and the middle part of the second guide groove 505 has a spiral structure. One end of the second guide shaft 504 extends into the interior of the second guide groove 505 and is slidably connected to the rotating shaft 502. Therefore, when the second guide shaft 504 moves at the spiral position in the middle of the second guide groove 505, the abutment 503 will rotate. When the second guide shaft 504 moves to the vertical position at the bottom of the second guide groove 505, the abutment 503 will rotate 90 degrees and be located at the bottom of the crossbar 402. Therefore, the abutment 503 can be prevented from blocking the cover plate 3 during the rotation of the cover plate 3.

[0027] As a technical optimization solution of this utility model, such as Figure 1 and Figure 2 As shown, a high-pressure air tank 7 is installed on the bag dust collector body 1. One end of the high-pressure air tank 7 is fixedly connected to an air blowing pipe 8, which is fixedly connected to the bag dust collector body 1. One end of the air blowing pipe 8 extends into the interior of the bag dust collector body 1. A pulse valve 9 is installed on the air blowing pipe 8. When it is necessary to clean the dust on the surface of the filter bag 10, the pulse valve 9 will open quickly. Then, the high-pressure gas inside the high-pressure air tank 7 will be blown from the end of the air blowing pipe 8 into the interior of the bag dust collector body 1. The high-pressure gas rushes into the interior of the filter bag 10 and causes the filter bag 10 to vibrate. The vibration of the filter bag 10 will shake off the dust attached to its surface, thereby realizing the automatic cleaning of the filter bag 10.

[0028] As a technical optimization solution of this utility model, such as Figure 1As shown, four support legs 14 are fixedly connected to the main body 1 of the bag dust collector, so the main body 1 of the bag dust collector can be supported by the support legs 14. The inner side of the filter bag 10 is provided with a support frame 11, so the inner side of the filter bag 10 can be supported by the support frame 11, so as to prevent the filter bag 10 from drying out under the action of negative pressure, thereby ensuring the dust removal effect of the filter bag 10.

[0029] As a technical optimization solution of this utility model, such as Figure 1 and Figure 3 As shown, an air inlet pipe 12 is fixedly connected to one side of the bag dust collector body 1, so that dust-laden gas can enter the interior of the bag dust collector body 1 from the air inlet pipe 12. An air outlet pipe 13 is fixedly connected to the other side of the bag dust collector body 1, so that filtered gas can be discharged from the air outlet pipe 13.

[0030] In use, this invention connects the dust conveying pipe to the inlet pipe 12 and the inlet pipe of the negative pressure fan to the outlet pipe 13. Under the action of the negative pressure fan, dust-laden gas enters the baghouse dust collector body 1 through the inlet pipe 12. As the gas flows through the baghouse dust collector body 1, dust is filtered by the filter bags 10. Some of the dust falls into the dust collection hopper at the bottom of the baghouse dust collector body 1 for collection, while the remaining dust adheres to the surface of the filter bags 10. The filtered air is then discharged through the outlet pipe 13. When cleaning the surface of the filter bags 10 is required, the pulse valve 9 opens rapidly, and high-pressure gas from the high-pressure gas tank 7 flows out from the end of the blowing pipe 8. High-pressure gas is blown into the interior of the baghouse dust collector body 1, causing the filter bags 10 to vibrate. This vibration dislodges dust adhering to the surface of the filter bags 10, thus achieving automatic cleaning. When the cover 3 needs to be opened for filter bag replacement, two electric push rods 401 are activated simultaneously. The extension of the electric push rods 401 drives the crossbar 402, which in turn drives two connecting plates 403. The connecting plates 403 then drive the first guide groove 404. Simultaneously, the first guide shaft 405 moves within the first guide groove 404. The movement of the crossbar 402 also drives multiple rotating shafts 502, which in turn drive the second guide shaft 504... The internal movement of the second guide groove 505 is such that when the second guide shaft 504 moves to the spiral position in the middle of the second guide groove 505, the abutment 503 will rotate. When the second guide shaft 504 moves to the vertical position at the bottom of the second guide groove 505, the abutment 503 will have rotated 90 degrees and be located at the bottom of the crossbar 402. Therefore, the abutment 503 can avoid blocking the cover plate 3 during the rotation of the cover plate 3. Then, the first guide shaft 405 will move to the inclined position at the lower part of the first guide groove 404. At this time, the slide rod 406 will slide on the guide seat 407. The movement of the slide rod 406 will drive the two racks 408 to move. The racks 408 drive the gears 409 to rotate. Since one rack 408 is located at the top of one gear 409, while the other... One rack 408 is located at the bottom of another gear 409. Therefore, the unidirectional movement of the two racks 408 will cause the two gears 409 to rotate in opposite directions. The rotation of gears 409 will drive the connecting shaft 2 to rotate, and the rotation of the connecting shaft 2 will cause the cover plate 3 to move away from the bag filter body 1. When the cover plate 3 rotates 180 degrees, the electric push rod 401 stops extending. At this time, the cover plate 3 will no longer block the filter bag 10, and the filter bag 10 can then be replaced. Therefore, by simultaneously activating the two electric push rods 401, the two cover plates 3 can be opened quickly, avoiding the need to use a wrench to turn multiple bolts to disassemble and install the cover plates 3. This shortens the opening time of the cover plates 3, facilitates the quick replacement of the filter bag 10, and improves the convenience of operation.Furthermore, when the cover plate 3 is placed on top of the baghouse dust collector body 1, the abutment block 503 applies low pressure to its end, thereby ensuring a tight seal between the cover plate 3 and the baghouse dust collector body 1, thus improving the sealing performance between the cover plate 3 and the baghouse dust collector body 1.
