[0023] 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.
[0024] Please see Figure 1-4 This utility model provides a technical solution: a dust collector bag with a tear-resistant structure, wherein a circular through groove matching the dust collector bag 2 is provided at the center of the mounting plate 1, and the dust collector bag 2 includes a support frame 201, and a dust collector bag body 202 is fixedly provided inside the support frame 201.
[0025] To further explain, the support frame 201 includes a ring 2011, and four sets of shaping rods 2012 are provided on the top of the ring 2011. A connecting plate 2013 is provided on the inner side of the ring 2011. By setting the support frame 201, the dustproof bag body 202 can be supported.
[0026] Specifically, the dust collector bag body 202 includes a base layer 2021, which is a glass fiber needle-punched felt structure. This base layer has advantages such as high temperature resistance, corrosion resistance, dimensional stability, minimal elongation and shrinkage, and high strength. It also has high porosity, resulting in low resistance to gas filtration and effectively preventing the dust collector bag from tearing, thus greatly improving the bag's mechanical strength. Tear-resistant layers 2022 are fixedly connected to both sides of the base layer 2021. These layers are made of nylon and spandex fibers, further enhancing tear resistance and improving the wear resistance and shape retention of the dust collector bag body 202. A flame-retardant layer 2023 is fixedly installed on the outside of the tear-resistant layer 2022. This flame-retardant layer 2023 provides excellent flame-retardant properties, preventing spontaneous combustion and burning of the dust collector bag body 202 during high-temperature gas dust removal. The flame-retardant layer 2023 is either magnesium hydroxide or aluminum hydroxide.
[0027] Specifically, the top of the support frame 201 and the dust bag body 202 is connected to the fixing frame 3, and a support rod 301 is installed inside the fixing frame 3. A bag cleaning mechanism 4 that works with the dust bag body 202 is set below the support rod 301. The bag cleaning mechanism 4 includes a rotating rod 401, and one end of the rotating rod 401 is connected to a drive motor 402 set above the support rod 301. The two sides of the rotating rod 401 are connected to a long-handled cleaning brush 404 through symmetrically arranged connecting rods 403, and the brush head in the long-handled cleaning brush 404 is in contact with the dust bag body 202.
[0028] When it is necessary to clean the blockage on the inner wall of the dustproof bag body 202, the drive motor 402 is turned on. Under the action of the drive motor 402, the rotating rod 401 rotates, thereby driving the long-handled cleaning brush 404 to rotate and move through the connecting rod 403. Under the action of the long-handled cleaning brush 404 rotating and moving, the blockage on the inner wall of the dustproof bag body 202 is brushed off.
[0029] Specifically, the top of the mounting plate 1 is symmetrically provided with a limiting insert plate mechanism 5 for use with the fixing frame 3. The limiting insert plate mechanism 5 includes an insert plate 501, and the fixing frame 3 is provided with an insert plate groove for use with the insert plate 501. The insert plate 501 is slidably connected to the sliding groove opened on the top of the mounting plate 1, and a spring 502 connected to the insert plate 501 is installed inside the sliding groove. A gripping plate 503 is provided on the top of the insert plate 501.
[0030] When it is necessary to remove the dust bag 2 for cleaning and maintenance, the insert plate 501 is moved by pulling the gripping plate 503. At this time, the spring 502 is in a compressed state. When the insert plate 501 is completely disengaged from the insert plate slot opened in the fixing frame 3, the fixing frame 3 can be lifted to remove the dust bag 2 for maintenance.
