[0002] Industrial dust collectors are also called industrial vacuum cleaners. Industrial dust collectors are equipment used for industrial purposes to collect and absorb waste medium particles, dust and smoke generated during production, operation and transportation. Some production equipment will generate a large amount of dust during the production process. The generated dust is connected to the dust collector through the suction pipe.

The dust collection assembly includes a dust collection trough 13, a first docking interface 14, a collection box 15 and a second docking interface 16. The dust collection trough 13 is opened at the bottom of the other end of the second cylinder 302, and the bottom of the dust collection trough 13 is integrally provided with a first docking interface 14, and the first docking interface 14 is connected and fixed to the second docking interface 16 arranged on the top of the collection box 15 by screws.

[0026] By arranging a dust collection assembly at the outer bottom of the air intake control mechanism, it is achieved that in the process of conveying the dust-laden gas through the intake valve, when the larger dust particles in the gas collide with the valve plate, the particles carried in the gas will be affected by gravity and sink downward along the dust collection groove 13 to the collection box 15 at the bottom, thereby effectively avoiding the accumulation of a lot of dust on the outer side of the valve plate during the conveying of the gas carrying dust particles, thereby affecting the air intake effect. The first docking port 14 and the second docking port 16 are fixed by screws, which facilitates the disassembly and cleaning of the collection box 15, and the surface of the valve plate inside the valve body can be cleaned through the dust collection groove 13.

[0027] The air intake control mechanism 6 includes a first valve plate 601, a first fan-shaped groove 602, a second valve plate 603 and a second fan-shaped groove 604. The first valve plate 601 is fixedly mounted on the inner side of the other end of the first cylinder 301, and the first valve plate 601 is provided with a first fan-shaped groove 602, and the second fan-shaped groove 604 is provided on the second valve plate 603. There are four first fan-shaped grooves 602 and second fan-shaped grooves 604. The air intake control mechanism 6 also includes an outer ring 605, an annular rack 606, a gear 607 and a servo motor 608. The outer ring 605 is integrally arranged on the outer side of the second valve plate 603. The thickness of the outer ring 605 is greater than that of the second valve plate 603, and an annular rack 606 is arranged on the outer side of the outer ring 605.

[0029] By arranging an air intake control mechanism 6 at the butt end of the first cylinder 301 and the other end of the second cylinder 302, the size of the airflow entering the dust collector can be controlled and regulated. The second sealing rings 10 on both sides of the outer ring 605 and the annular rack 606 on the outer side of the second valve plate 603 are respectively rotated in the second annular groove 8 and the second sealing groove 9 to support the second valve plate 603. The servo motor 608 is driven to make its output shaft drive the gear 607 to rotate. Since the gear 607 is meshed with the annular rack 606 on the outer side of the outer ring 605, the second valve plate 603 is driven to rotate closely against the first valve plate 601. The size of the airflow can be controlled and regulated by the misalignment between the first fan-shaped groove 602 and the second fan-shaped groove 604. When the second fan-shaped groove 604 on the second valve plate 603 rotates to correspond to the first fan-shaped groove 602 on the first valve plate 601, the air flow is maximum at this time.

[0030] A positioning shaft 11 is arranged at the center of the first valve plate 601, and the side wall of the positioning shaft 11 is rotatably connected to a positioning groove 12 at the center of the second valve plate 603. By setting the positioning shaft 11 and the positioning groove 12, a tight fit between the first valve plate 601 and the second valve plate 603 is achieved, and a stabilizing effect is played.

[0031] Embodiment 2:

[0032] Based on the first embodiment, the docking assembly 4 mentioned in the first embodiment is described. The docking assembly 4 includes an outer cylinder 401, a first positioning ring 402, a second positioning ring 403, a first sealing groove 404, a first sealing ring 405 and a connecting flange 406. The first positioning ring 402 is integrally arranged at one end of the outer cylinder 401, and the first positioning ring 402 is slidably connected to the outer walls of the first cylinder 301 and the second cylinder 302. The inner wall of the outer cylinder 401 is integrally arranged at the outer ends of the first cylinder 301 and the second cylinder 302. The side wall of the second positioning ring 403 is slidably connected, and a first sealing groove 404 is opened on one side of the second positioning ring 403. The first sealing groove 404 is adapted to a first sealing ring 405 arranged on one side of the first positioning ring 402. A connecting flange 406 is arranged at the other end of the outer tube 401, and the connecting flange 406 is fixed to the flange connection of the interface of the air inlet pipe 2 and the air delivery pipe 5 by bolts. A sealing ring 7 is arranged on the inner side of the first sealing groove 404, and the sealing ring 7 is used for sealing connection between the first sealing groove 404 and the first sealing ring 405.

[0033] In this embodiment, since the air pipeline of the industrial dust collector is mostly set to be fixed, after the air intake valve and the air pipeline are fixed by bolt connection, it is inconvenient to dock it with the fixed air pipeline again after the air intake valve is disassembled and maintained separately, so that it is easy to have insufficient sealing during the re-docking installation process, affecting the sealing effect. The air intake valve is connected and fixed to the air intake pipe 2 and the air pipeline 5 by the docking assembly 4, which is convenient for disassembling and assembling the air intake valve without disassembling the air pipeline 5, thereby improving the convenience of disassembly and assembly, and utilizing the outer surface of the valve body 3 to facilitate disassembly and assembly. A first positioning ring 402 is slidably provided on the side wall, so that during installation, the outer tube 401 is directly pulled toward the butt joint end of the air intake pipe 2 and the air supply pipe 5, so that the first sealing ring 405 on the first positioning ring 402 at one end of the outer tube 401 is inserted into the first sealing groove 404 and contacts the sealing ring 7 at the same time, and then the connecting flange 406 is connected and fixed to the flanges on the air intake pipe 2 and the air supply pipe 5 by bolts, and a sealing gasket can be provided between the flanges to improve the sealing of the butt joint, thereby realizing the disassembly and assembly of the air intake valve without disassembling the air supply pipe 5.

[0034] Working principle: When it is necessary to adjust the size of the airflow entering the dust collector through the air intake valve, the servo motor 608 is directly driven to drive the second valve plate 603 to rotate inside the butt end of the first cylinder 301 and the second cylinder 302, so as to achieve the misalignment between the second fan-shaped groove 604 and the first fan-shaped groove 602 on the fixed first valve plate 601 to adjust the size of the airflow. During the use of the air intake valve, the dust collection groove 13 and the collection box 15 arranged at the bottom of the outer side of the second valve plate 603 are used to collect the dust particles in the airflow that hits the valve plate. The collection box 15 is removed by removing the screws. The dust particles collected inside can be processed during disassembly. At the same time, a brush can be inserted into the interior of the valve body 3 through the dust collection groove 13 to clean the dust on the surface of the valve plate. When the entire intake valve needs to be disassembled and maintained, the bolts at the connecting ends of the intake pipe 2 and the gas supply pipe 5 are directly removed, and then the valve seat 17 is removed from the valve seat mounting seat to realize disassembly of the entire intake valve. After the maintenance is completed, the valve seat 17 is fixed on the valve seat mounting seat, and the outer cylinder 401 slidingly arranged on the first cylinder 301 and the second cylinder 302 is horizontally moved to realize the connecting and fixing of the intake pipe 2 and the gas supply pipe 5, thereby improving the convenience of disassembly and assembly.
