Description
A filter assembly for a pulse dust collector Technical Field
[0001] This utility model relates to a filter assembly, specifically a filter assembly for a pulse dust collector, belonging to the technical field of dust removal equipment. Background Technology
[0002] Pulse jet dust collectors are commonly used high-efficiency dust removal equipment in the industrial field. They are mainly used to separate dust particles from gases, purify industrial waste gases, and improve air quality. Their internal filtration components are mainly composed of multiple filter bags. Through the interception effect of the filter bags, dust particles (such as PM2.5, PM10, etc.) in dust-laden gases are efficiently separated, so that the purified gases meet national or local emission standards. Furthermore, they use a pulse backflushing mechanism to automatically clean the dust adhering to the outside of the filter bags, thus facilitating continuous dust removal.
[0003] However, in practical applications, dust may clump together on the outer wall of the filter bag due to factors such as humidity and stickiness. Traditional pulse backflushing can hardly completely remove the clumped dust by airflow impact alone, resulting in incomplete dust removal, increased filter bag resistance, and affecting dust removal efficiency and equipment operation stability. Summary of the Invention
[0004] The purpose of this invention is to provide a filter component for a pulse dust collector to solve the above-mentioned problems. By combining mechanical knocking with pulse backflushing, it solves the problem that dust clumps on the surface of the filter bag and is difficult to clean by pulse alone, thereby improving the dust removal effect and filtration efficiency.
[0005] This utility model achieves the above-mentioned objective through the following technical solution: a filter assembly for a pulse dust collector, comprising a support plate, multiple filter bags mounted on the support plate, multiple connecting sleeves fixedly connected to the support plate, a drive structure on the support plate, and a striking structure on the connecting sleeve, the striking structure comprising a rotating sleeve and a gear ring, a rotating sleeve rotatably connected to the outer side of the connecting sleeve, a connecting shaft rotatably connected to the rotating sleeve, a connecting frame fixedly connected to the bottom side of the support plate, multiple gear rings fixedly connected to the connecting frame, a gear fixedly connected near the top of the connecting shaft, the gear meshing with an adjacent gear ring, one synchronous pulley fixedly connected near the bottom of the connecting shaft, a long shaft rotatably connected to the rotating sleeve, another synchronous pulley fixedly connected near the top of the long shaft, a synchronous belt wound between the two synchronous pulleys, and multiple flexible belts fixedly connected to the long shaft.

[0007] Preferably, the multiple soft strips located on the same side of the long axis are linearly and equidistantly distributed, and the multiple soft strips located on both sides of the long axis are arranged in a circular array about the axis of the long axis.
[0008] Preferably, a support frame is installed on the support plate, and the bottom end of the support frame extends into the interior of the filter bag.
[0009] Preferably, the drive structure includes a motor and a first pulley. The motor is mounted on the top side of the support plate, and the first pulley is fixedly connected to the output shaft of the motor. A second pulley is fixedly connected to the outer side of the rotating sleeve. A first belt is wound between one of the second pulleys and the first pulley. A second belt is wound between two adjacent second pulleys in the transverse direction. A second belt is wound between one of the leftmost second pulleys in the middle transverse row and one of the leftmost second pulleys in the front transverse row. A second belt is wound between one of the rightmost second pulleys in the middle transverse row and one of the rightmost second pulleys in the rear transverse row.
[0010] Preferably, the support plate is provided with a shielding structure, the shielding structure includes guide rods and slides, two guide rods are fixedly connected to the top side of the support plate, multiple baffles are provided on the top side of the support plate, two slides are fixedly connected to the top side of the baffles, and the slides are slidably connected to the adjacent guide rods.
[0011] Preferably, two electric push rods are installed on the support plate, one end of the two electric push rods is fixedly connected to the same moving plate, multiple guide shafts are fixedly connected to the moving plate, the baffle is provided with guide grooves, and the guide shafts extend into the interior of adjacent guide grooves and are slidably connected to the baffle.
[0012] Preferably, the two slide blocks are symmetrically distributed about the middle of the baffle, and the guide groove is inclined.
[0013] The beneficial effects of this utility model are as follows: When the filter bag needs to be cleaned, multiple rotating sleeves will rotate simultaneously under the action of the drive structure. The rotation of the rotating sleeves will drive the connecting shaft to move, and the movement of the connecting shaft will drive the gear to move. Since the gear and the gear ring are meshed, the gear will rotate during the movement. The rotation of the gear will drive the connecting shaft to rotate, and the rotation of the connecting shaft will drive one of the synchronous pulleys to rotate. The rotation of one of the synchronous pulleys will drive another synchronous pulley to rotate through the synchronous belt. The rotation of the other synchronous pulley will drive the long shaft to rotate, and the rotation of the long shaft will drive multiple soft belts to rotate. During the rotation of the soft belts, the soft belts will knock on the outside of the filter bag. As the rotating sleeves rotate, the long shaft will move in a circular motion on the outside of the filter bag, thereby realizing all-round knocking on the outside of the filter bag. Therefore, before pulse backflushing cleaning, the filter bag can be knocked evenly, so that the dust clumps on the outside of the filter bag and the filter bag will be loosened. Thus, during pulse backflushing cleaning, all the dust adhering to the outside of the filter bag can be cleaned, which will improve the cleaning effect. Attached Figure Description

[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 refer to Figures 1-6. A filter assembly for a pulse dust collector includes a support plate 1, on which multiple filter bags 2 are mounted. Multiple connecting sleeves 3 are fixedly connected to the support plate 1. The support plate 1 is provided with a driving structure 6. The connecting sleeves 3 are provided with a striking structure 5. The striking structure 5 includes a rotating sleeve 501 and a toothed ring 502. The rotating sleeve 501 is rotatably connected to the outer side of the connecting sleeves 3. A connecting shaft 504 is rotatably connected to the rotating sleeve 501. A connecting frame 8 is fixedly connected to the bottom side of the support plate 1. Multiple gear rings 502 are fixedly connected to the upper part. A gear 503 is fixedly connected to the upper part of the connecting shaft 504 near the top. The gear 503 meshes with the adjacent gear ring 502. One of the synchronous pulleys 505 is fixedly connected to the lower part of the connecting shaft 504. A long shaft 507 is rotatably connected to the rotating sleeve 501. Another synchronous pulley 505 is fixedly connected to the upper part of the long shaft 507 near the top. A synchronous belt 506 is wound between the two synchronous pulleys 505. Multiple soft belts 508 are fixedly connected to the long shaft 507.
[0023] As a technical optimization of this utility model, the axis of the connecting sleeve 3 and the adjacent filter bag 2 are on the same straight line, and the axis of the gear ring 502 and the axis of the connecting sleeve 3 are on the same straight line. Therefore, when the gear 503 moves in a circular motion around the connecting sleeve 3, it can rotate itself.
[0024] As a technical optimization of this utility model, the multiple soft strips 508 located on the same side of the long axis 507 are linearly and equidistantly distributed, and the multiple soft strips 508 located on both sides of the long axis 507 are arranged in a circular array about the axis of the long axis 507. Therefore, the range and frequency of the tapping can be increased, thereby facilitating the improvement of the tapping effect.
[0025] As a technical optimization of this utility model, a support frame 4 is installed on the support plate 1, so that the filter bag 2 can be supported by the support frame 4, and the filter bag 2 can be prevented from deforming under pressure. The bottom end of the support frame 4 extends into the interior of the filter bag 2.
[0026] As a technical optimization of this utility model, the drive structure 6 includes a motor 601 and a first pulley 602. The motor 601 is installed on the top side of the support plate 1, so the first pulley 602 can be driven to rotate by the motor 601. The first pulley 602 is fixedly connected to the output shaft of the motor 601. A second pulley 604 is fixedly connected to the outer side of the rotating sleeve 501. A first belt 603 is wound between one of the second pulleys 604 and the first pulley 602. A second belt 605 is wound between two adjacent second pulleys 604 in the horizontal direction. A second belt 605 is wound between one of the leftmost second pulleys 604 in the middle horizontal row and one of the leftmost second pulleys 604 in the front horizontal row. A second belt 605 is wound between one of the rightmost second pulleys 604 in the middle horizontal row and one of the rightmost second pulleys 604 in the rear horizontal row. Therefore, when one of the rotating sleeves 501 rotates, all the rotating sleeves 501 can rotate.
[0027] As a technical optimization of this utility model, the support plate 1 is provided with a shielding structure 7, which includes a guide rod 701 and a slide block 702. Two guide rods 701 are fixedly connected to the top side of the support plate 1, and multiple baffles 703 are provided on the top side of the support plate 1. Therefore, during pulse cleaning, the baffles 703 can shield the bag opening of the filter bag 2 to a certain extent, thereby increasing the impact force of the pulse gas and improving the cleaning effect. Two slide blocks 702 are fixedly connected to the top side of the baffle 703. The two slide blocks 702 are symmetrically distributed about the middle of the baffle 703. The slide blocks 702 are slidably connected to the adjacent guide rods 701, so the movement of the baffle 703 can be guided by the slide blocks 702 sliding on the guide rods 701.
[0028] As a technical optimization of this utility model, two electric push rods 707 are installed on the support plate 1. The movement of the moving plate 706 can be controlled by the two electric push rods 707. One end of the two electric push rods 707 is fixedly connected to the same moving plate 706. Multiple guide shafts 705 are fixedly connected to the moving plate 706. The baffle 703 is provided with a guide groove 704. The guide groove 704 is inclined. The guide shaft 705 extends into the interior of the adjacent guide groove 704 and is slidably connected with the baffle 703. Therefore, during the movement of the moving plate 706, the two baffles 703 on both sides of the filter bag 2 can move towards the filter bag 2 at the same time.
[0029] In use, when the filter bag 2 needs to be cleaned, the motor 601 is started. The output shaft of the motor 601 rotates, driving the first pulley 602 to rotate. The rotation of the first pulley 602 drives one of the second pulleys 604 to rotate via the first belt 603. The rotation of the second pulleys 604 drives the rotating sleeve 501 to rotate. The rotation of one second pulley 604 drives the next adjacent second pulley 604 via the second belt 605. This process is repeated to make all the second pulleys 604 rotate, thereby causing multiple rotating sleeves to rotate. Simultaneous rotation of sleeve 501 drives the connecting shaft 504, which in turn drives gear 503. Since gear 503 meshes with gear ring 502, gear 503 rotates during its movement. This rotation drives the connecting shaft 504, which in turn drives one of the synchronous pulleys 505. This rotation, via synchronous belt 506, drives another synchronous pulley 505, which in turn drives the long shaft 507. The movement drives multiple flexible belts 508 to rotate. During rotation, the flexible belts 508 tap the exterior of the filter bag 2. As the rotating sleeve 501 rotates, the long shaft 507 moves circumferentially around the exterior of the filter bag 2, achieving comprehensive tapping of the filter bag 2's exterior. Therefore, before pulse backflushing cleaning, the filter bag 2 can be evenly tapped, loosening the dust clumps on its exterior and allowing for thorough cleaning of the dust adhering to the exterior during pulse backflushing, thus improving cleaning efficiency. Furthermore, before pulse cleaning, the system can simultaneously activate... Moving two electric push rods 707 simultaneously extends their ends, causing the moving plate 706 to move. The movement of the moving plate 706 causes multiple guide grooves 704 to move. While the guide grooves 704 are moving, the guide shaft 705 moves inside the guide grooves 704, causing the two baffles 703 on both sides of the filter bag 2 to move closer to the filter bag 2. This creates a certain degree of shielding at the bag opening of the filter bag 2, preventing a large amount of high-pressure gas from overflowing from the bag opening and thus reducing the impact force, thereby further improving the dust removal effect.
