[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0018] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0019] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0021] like Figure 1-4 As shown, this embodiment proposes a high-temperature resistant composite fiber gradient filter dust collector bag, including a frame 1, and a filter screen assembly 2 and a dust collector bag assembly 3 are arranged on the outside of the frame 1. The filter assembly 2 includes a first filter 201, a Velcro round bristle 202, a sleeve 203, a second filter 204, a Velcro barb 205, and a positioning block 206; The first filter 201 is detached from and connected to the second filter 204 and the frame 1. The Velcro loops 202 are sewn to one side of the first filter 201. The sleeve 203 is attached to the other side of the Velcro loops 202. The Velcro barbs 205 are attached to the outside of the frame 1. The positioning block 206 is fixedly attached to the inside of the frame 1.

[0022] like Figure 3As shown, the second filter screen 204 is bonded to the sleeve 203, and the inner diameter of the filter holes on the surface of the first filter screen 201 is larger than the inner diameter of the filter holes on the surface of the second filter screen 204. This allows the first filter screen 201 in its installed state to perform a first filtration of impurities in the incoming gas, and the second filter screen 204 in its installed state to perform a second filtration of impurities in the incoming gas.

[0023] like Figure 3 As shown, the positioning block 206 is used for the sleeve 203 to be fitted onto its exterior. The sleeve 203 and positioning block 206 in the engaged state pre-limit the positions of the first filter screen 201 and the second filter screen 204. The sleeve 203 is fitted onto the outside of the positioning block 206, so that the sleeve 203 and positioning block 206 in the engaged state pre-limit the positions of the first filter screen 201 and the second filter screen 204.

[0024] like Figure 3 As shown, the aligned loops 202 and loops 205 are glued together, and the glued loops 202 and loops 205 are used to lock the positions of the first filter 201 and the second filter 204. When the loops 202 and loops 205 are aligned, they are glued together, and the glued loops 202 and loops 205 lock the positions of the first filter 201 and the second filter 204.

[0025] like Figure 4 As shown, the dust bag assembly 3 includes a surface layer 301, a substrate layer 302, a filter layer 303, and a mounting bracket 304; Mounting bracket 304 is detachably connected to frame 1 via screws. Substrate layer 302 is disposed inside mounting bracket 304, inside surface layer 301, and filter layer 303 is disposed inside substrate layer 302. Gas that has undergone two filtrations flows into surface layer 301, substrate layer 302, and filter layer 303. Because substrate layer 302 has a three-dimensional mesh structure, the irregularly shaped cross-section fibers are orthogonally woven into a three-dimensional network with interconnected pores in the XYZ directions. Substrate layer 302 effectively improves the high-temperature resistance of filter layer 303 and surface layer 301, and filter layer 303 performs a third filtration on the gas after the first two filtrations, thus effectively improving filtration performance through the aforementioned structure.

[0026] like Figure 4As shown, the substrate layer 302 has a three-dimensional mesh structure and is used to improve the high-temperature resistance of the filter layer 303 and the surface layer 301. Because the substrate layer 302 has a three-dimensional mesh structure, the irregularly shaped cross-section fibers are orthogonally woven into a three-dimensional network with interconnected pores in the XYZ three-dimensional directions, effectively improving the high-temperature resistance of the filter layer 303 and the surface layer 301.

[0027] like Figure 4 As shown, filter layer 303 is used to improve filtration performance. The filter layer 303 performs a third filtration on the gas that has already undergone two filtrations, thereby effectively improving filtration performance through the aforementioned structure.

[0028] Specifically, when using a high-temperature resistant composite fiber gradient filter dust collector bag: First, the first filter screen 201 and the second filter screen 204 are installed. The sleeve 203 is placed on the outside of the positioning block 206, so that the sleeve 203 and the positioning block 206 in the locked state pre-limit the position of the first filter screen 201 and the second filter screen 204. At this time, the Velcro round hairs 202 and the Velcro barbs 205 are aligned. Then, the aligned Velcro round hairs 202 and the Velcro barbs 205 are glued together. The glued Velcro round hairs 202 and the Velcro barbs 205 lock the position of the first filter screen 201 and the second filter screen 204. The first filter screen 201 and the second filter screen 204 are installed on the frame 1. The first filter screen 201 in the installed state performs the first filtration of impurities in the incoming gas, and the second filter screen 204 in the installed state performs the second filtration of impurities in the incoming gas. It is also convenient to disassemble and replace the first filter screen 201 and the second filter screen 204. The gas, after being filtered twice, flows into the surface layer 301, the substrate layer 302, and the filter layer 303. Since the substrate layer 302 has a three-dimensional mesh structure, the irregular cross-section fibers are formed by multiple orthogonally woven layers to form a three-dimensional network with XYZ three-dimensional through-pores. The substrate layer 302 effectively improves the high-temperature resistance of the filter layer 303 and the surface layer 301, and the filter layer 303 performs a third filtration on the gas after the two filtrations, thereby effectively improving the filtration performance through the above structure.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
