[0001] The utility model relates to the technical field of dust removal filter bags, in particular to a room temperature polyester needle felt dust removal filter bag. Background Art

[0002] Polyester needle felt is often used to make dust filter bags. The common dust filter bags on the market are all columnar in structure with arc-shaped outer walls. When filtering and cleaning the gas mixed with dust, dust tends to accumulate on the outer surface of the bag. Due to the arc-shaped curved surface structure of the columnar dust filter bag, its contact area with the gas is limited, so the dust filter bag needs to be frequently disassembled and cleaned, affecting the smoothness and continuity of the work.

[0003] In order to solve the above problems, the present application proposes a room temperature polyester needle felt dust removal filter bag. Utility Model Content

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model proposes a normal temperature polyester needle felt dust removal filter bag, comprising a bag body 1 and a dust collecting member 2, wherein the dust collecting member 2 is sleeved on the outside of the bag body 1;

[0028] The bag body 1 comprises a columnar sleeve 101, a corrugated filter cartridge 102, a connecting cartridge 103 and an assembling cartridge 104. The bottom opening end and the top opening end of the corrugated filter cartridge 102 are fixedly connected to the columnar sleeve 101 and the connecting cartridge 103 respectively. The assembling cartridge 104 is arranged on the top of the connecting cartridge 103.

[0029] The dust collecting member 2 comprises a rubber hoop 201 and a polyester needle felt sheath 202 . The polyester needle felt sheath 202 is fixedly connected to the end surface of the rubber hoop 201 . An arc-shaped groove 203 is arranged on the circumference of the surface of the polyester needle felt sheath 202 .

[0030] The rubber hoop 201 and the polyester needle felt sheath 202 are both sleeved on the columnar sleeve 101 of the bag body 1 , and a dust collecting groove is provided between the polyester needle felt sheath 202 and the outer wall of the columnar sleeve 101 .

[0031] It should be noted that the bag body 1 installed inside the dust collecting part 2 includes a cylindrical sleeve 101, a corrugated filter cylinder 102, a connecting cylinder 103 and an assembly cylinder 104, which changes the appearance design of the traditional cylindrical smooth curved surface. The corrugated filter cylinder 102 is installed between the cylindrical sleeve 101 and the connecting cylinder 103. The corrugated filter cylinder 102 increases the contact area between the bag body 1 and the air. When performing filtering operations, the corrugated surface of the corrugated filter cylinder 102 is not prone to a large amount of dust that affects its air permeability, thereby extending the filtering time and reducing the frequency of replacing the filter bag, thereby improving the smoothness and continuity of the work.

[0032] Example 2

[0033] In this embodiment, if Figure 2 As shown, the inner wall of the corrugated filter cartridge 102 is an arc-shaped smooth curved surface, and the outer surface of the corrugated filter cartridge 102 is provided with a conical boss 105 , and the outer wall of the conical boss 105 protrudes from the end surface position of the columnar sleeve 101 .

[0034] It should be noted that the inner wall of the corrugated filter cartridge 102 is an arc-shaped smooth curved surface.
