They have anti-static properties and can provide good filtering effects while preventing static electricity accumulation.

[0003] During the filtration process of the existing filter cloth bag, dust accumulates on the surface of the filter cloth, which will cause the dust filtration area of ​​the filter cloth bag to decrease. Therefore, the filter cloth bag needs to be replaced and maintained after a certain period of use. The existing filter cloth bag is often fixed to the bracket of the dust collector by a specific fixing device (such as a hook, a buckle, etc.), which is troublesome to replace.

[0004] For this reason, a multi-layer antistatic industrial filter cloth bag is proposed. Utility Model Content

[0024] like Figures 1 to 5As shown, a multi-layer antistatic industrial filter cloth bag comprises a dust collector frame 1 and a filter bag ring frame 2, a filter cloth bag body 3 is fixedly mounted on the bottom surface of the filter bag ring frame 2, a side panel 4 is fixedly mounted on the top surface of the dust collector frame 1, and a through groove 41 is opened on the surface of the side panel 4, a pull rod assembly 5 is inserted and installed inside the through groove 41, and a spring 6 is sleeved on the surface of the pull rod assembly 5, and a locking tongue 7 is fixedly mounted on one end of the spring 6 of the pull rod assembly 5. More specifically, when the filter bag ring frame 2 is installed, the filter bag ring frame 2 and the side plate 4 on the top surface of the dust collector frame 1 are correspondingly plugged in. When plugging in, the surface of the filter bag ring frame 2 and the surface of the locking tongue 7 are in contact, so that the pull rod assembly 5 moves laterally to compress the spring 6. Under the elastic force of the spring 6, when the bottom surface of the filter bag ring frame 2 and the top surface of the dust collector frame 1 are fitted, the locking tongue 7 is plugged into the locking position on the surface of the filter bag ring frame 2, so that the filter bag ring frame 2 is installed and fixed. When disassembling, the pull rod assembly 5 is pulled to drive the locking tongue 7 to move laterally, so that the spring 6 is compressed, thereby realizing the separation of the locking tongue 7 and the locking position of the filter bag ring frame 2, and releasing the lock of the filter bag ring frame 2.

[0025] The filter bag ring frame 2 includes a ring body 201, a slot 202 is provided on the surface of the ring body 201, and an inclined groove 203 is provided on the bottom surface of the ring body 201. The inclined groove 203 is located below the slot 202, and the inclined groove 203 and the slot 202 are arranged correspondingly. More specifically, when the filter bag ring frame 2 is installed, the inclined groove 203 on the bottom surface of the ring body 201 contacts the inclined surface of the locking tongue 7, so that when the slot 202 is pressed down for installation, the locking tongue 7 is pushed to move horizontally through the inclined groove 203, and the ring body 201 is locked through the internal plugging of the locking tongue 7 and the slot 202.

[0026] The filter bag body 3 includes a support frame 301, the bottom surface of the ring body 201 is fixedly mounted with the support frame 301, and the surface of the support frame 301 is fixedly mounted with multiple sets of metal meshes 302, and the bottom surface of the ring body 201 is fixedly mounted with a filter layer 303 and an antistatic layer 304. More specifically, the metal mesh 302 enables dust to be filtered, and the filter layer 303 uses conductive fibers or adds antistatic materials to achieve antistatic properties, which helps prevent dust from accumulating due to static electricity, reduces dust adhesion, and prolongs the service life.

[0027] The pull rod assembly 5 comprises a rectangular rod 501, the rectangular rod 501 is movably inserted in the through slot 41, a pull block 502 is fixedly installed at one end of the rectangular rod 501, a connecting column 503 is fixedly installed at the other end of the rectangular rod 501, a locking tongue 7 is rotatably installed at the other end of the connecting column 503, and the other end of the spring 6 is fixedly installed with a side wall of the locking tongue 7, a limiting convex shaft 504 is fixedly installed on the top surface of the rectangular rod 501, and the surfaces of the rectangular rod 501 and the connecting column 503 are sleeved with the spring 6. More specifically, when the filter bag ring frame 2 is disassembled, the locking tongue 7 is driven to move horizontally by pulling the pull block 502, so that the spring 6 is compressed, so that the limiting convex shaft 504 passes through the through slot 41, and the rotating pull block 502 drives the rectangular rod 501, the connecting column 503 and the limiting convex shaft 504 to rotate, so that the limiting convex shaft 504 and the through slot 41 are misaligned, so that the lateral position of the locking tongue 7 after unlocking can be limited, which is convenient for disassembling the filter bag ring frame 2.

[0028] The interface of the locking tongue 7 is arranged in a wedge-shaped structure, and when the filter bag ring frame 2 is fixed, the locking tongue 7 and the card slot 202 are arranged in a plug-in installation. More specifically, the locking tongue 7 and the card slot 202 are plugged in and then the ring body 201 is fixed.

[0029] The through slot 41 is provided in a convex structure, and the limiting convex shaft 504 is provided correspondingly to the upper part of the through slot 41. More specifically, the limiting convex shaft 504 corresponds to the upper part of the through slot 41 so that the limiting convex shaft 504 can pass through when disassembling, and the locking tongue 7 can be temporarily limited after being displaced.

[0030] In summary: when the filter bag ring frame 2 is installed, the side panels 4 on the top surface of the filter bag ring frame 2 and the dust collector frame 1 are correspondingly plugged in. When plugging in, the surface of the filter bag ring frame 2 and the surface of the locking tongue 7 are in contact, so that the pull rod assembly 5 moves laterally to compress the spring 6. Under the elastic force of the spring 6, when the bottom surface of the filter bag ring frame 2 and the top surface of the dust collector frame 1 are fitted, the locking tongue 7 is plugged into the locking position on the surface of the filter bag ring frame 2, so that the filter bag ring frame 2 is installed and fixed. When disassembling, the lock tongue 7 is driven to move laterally by pulling the pull rod assembly 5, so that the spring 6 is compressed, thereby realizing the separation of the locking tongue 7 and the locking position of the filter bag ring frame 2, and releasing the lock of the filter bag ring frame 2.
