DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the utility model with reference to the accompanying drawings in the embodiments of the utility model.

[0019] The utility model provides a technical solution: as Figure 1 - Figure 4As shown in the figure, in this embodiment, a tensile and wear-resistant filter bag includes a filter bag body 1. One end of the filter bag body 1 is sewn with a bag mouth sleeve 2. One side of the inner wall of the bag mouth sleeve 2 is fixedly connected with a fixed frame 3. One side of the inner wall of the fixed frame 3 is rotatably connected with a fixing plate 5. Both sides of the outer surface of the fixing plate 5 are fixedly connected with bumps 8. Both sides of the inner wall of the fixed frame 3 are provided with fixed grooves 7. The outer surfaces of the two bumps 8 are respectively clamped with the inner walls of the two fixed grooves 7. One side of the fixed frame 3 is fixedly connected with a support frame 4. The support frame 4 is located inside the bag mouth sleeve 2. One side of the outer surface of the support frame 4 is clamped with one side of the fixing plate 5. By removing the fixing plate 5 from the fixed frame 3, the restriction on one end of the support frame 4 is released, and the support frame 4 is pulled outwards, so as to adjust the size of the support frame 4 inside the bag mouth sleeve 2. After the adjustment is completed, rotate the fixing plate 5 and clamp one end of the fixing plate 5 on one side of the surface of the support frame 4 to fix the support frame 4, thereby realizing the adjustment of the bag mouth size of the filter bag body 1 and improving the versatility of the filter bag body 1. Among them, the support frame 4 is made of PE plastic.

[0020] As Figure 2 and Figure 3 shown, one end of the fixing plate 5 is fixedly connected with a plurality of rubber strips 6. One side of each of the plurality of rubber strips 6 is attached to the outer surface of the support frame 4. Through the structural design of the rubber strips 6, when the fixing plate 5 is clamped in the fixed frame 3, the elasticity of the rubber strips 6 themselves can more stably clamp the support frame 4 in the fixed frame 3 to prevent the support frame 4 from sliding.

[0021] As Figure 2 and Figure 3 shown, a taking groove 9 is provided on the other side of the inner wall of the fixed frame 3. Through the structural design of the taking groove 9, it is convenient for the staff to remove the fixing plate 5 from the fixed frame 3.

[0022] As Figure 4 shown, the filter bag body 1 includes a first filter cloth 10. An installation groove 11 is provided on the upper surface of the first filter cloth 10. A nylon rope 12 is bonded to the inner wall of the installation groove 11. A second filter cloth 13 is bonded to the outer surface of the installation groove 11. The second filter cloth 13 and the first filter cloth 10 are made of polyester fiber. An inner wear-resistant layer 14 is bonded to the upper surface of the second filter cloth 13. The inner wear-resistant layer 14 is made of wide-woven plain cotton cloth. Through the structural design of the nylon rope 12, the pulling strength of the filter bag body 1 can be improved, and the service life of the filter bag body 1 can be extended.

[0023] As Figure 4 shown, a heat-resistant layer 15 is bonded to the lower surface of the first filter cloth 10. The heat-resistant layer 15 is made of aramid fiber. Through the structural design of the heat-resistant layer 15, the heat resistance of the filter bag body 1 is improved.

[0024] As Figure 4As shown, the lower surface of the heat-resistant layer 15 is adhesively bonded with an outer wear-resistant layer 16. The outer wear-resistant layer 16 is made of wide-woven plain cotton cloth. Through the structural design of the outer wear-resistant layer 16, the wear resistance of the filter bag body 1 is improved, preventing it from being scratched during installation and affecting the service life of the filter bag body 1.

[0025] The present utility model provides a tensile and wear-resistant filter bag, and the specific working principle is as follows:

[0026] When installing the filter bag on the equipment, first measure the size of the equipment installation port, then buckle out the fixing plate 5 from the fixing frame 3, release the restriction at one end of the support frame 4, pull the support frame 4 outwards, adjust the size of the support frame 4 within the bag mouth sleeve 2, and the adjusted size is the same as the size of the equipment installation port. Rotate the fixing plate 5, and fix one end of the fixing plate 5 on one side of the surface of the support frame 4, then cut off the excess support frame 4, and install the filter bag body 1 on the equipment.
