[0005] The technical problem solved by the utility model is achieved by the following technical solutions:

[0006] A dust removal filter bag comprises a bag-shaped filter cloth with an opening, and also comprises a ring body, an annular groove is arranged on the outer side of the ring body, and the filter cloth wraps the ring body at the opening.

[0007] Furthermore, the ring body includes a main ring, a top outer ring and a bottom outer ring rolled outward from the top edge and bottom edge of the main ring, a top inner ring rolled from the top outer ring into the space between the main ring and the top outer ring, and a bottom inner ring rolled from the bottom outer ring into the space between the main ring and the bottom outer ring.

[0008] Furthermore, the main ring, the top inner ring, and the top outer ring are fixed in sequence.

[0009] Furthermore, the main ring, the bottom inner ring, and the bottom outer ring are fixed in sequence.

[0010] Furthermore, the filter cloth is rolled outward or inward from the opening and fixed to form a hollow ring cavity, and the ring body is arranged in the ring cavity.

[0011] Furthermore, it also includes a metal ring, which is arranged in the ring cavity and located inside the ring body.

[0012] Furthermore, it also includes a ring cloth strip, which is fixed on the bottom of the filter cloth.

[0013] Furthermore, the fixation is fixation by suture connection.

[0014] Furthermore, the ring body material is felt.

[0015] The beneficial effects of the utility model are:

[0016] The utility model provides an annular groove on the outer side of the ring body, and the filter cloth wraps the ring body at the opening, so that the dust filter bag is installed at the air inlet, and when the fixing ring for fixing is tied to the filter cloth outside the annular groove, the filter cloth here forms a concave position for fixing the fixing ring, so that the fixing ring is firmly sunk into the concave position for fixing, and the installation is firm, which solves the problem that the traditional dust filter bag cannot withstand the impact of strong wind and is easy to fall off.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0023] See also Figures 1 to 3 A dust filter bag includes a bag-shaped filter cloth 2 with an opening 1, and a ring body 3. An annular groove 4 is provided on the outer side of the ring body 3, and the filter cloth 2 wraps the ring body 3 at the opening 1. By providing the annular groove 4 on the outer side of the ring body 3, the filter cloth 2 wraps the ring body 3 at the opening 1, so that when the dust filter bag is installed at the air inlet, when the fixing ring is tied to the filter cloth 2 outside the annular groove 4, the filter cloth 2 here forms a concave position for the fixing ring to fix, so that the fixing ring is firmly sunk into the concave position for fixing, and the installation is firm, which solves the problem that the traditional dust filter bag cannot withstand the impact of strong wind and is easy to fall off.

[0024] The ring body 3 includes a main ring 5, a top outer ring 6 and a bottom outer ring 7 rolled out from the top edge and the bottom edge of the main ring 5, a top inner ring 60 rolled in between the main ring 5 and the top outer ring 6 from the top outer ring 6, and a bottom inner ring 70 rolled in between the main ring 5 and the bottom outer ring 7 from the bottom outer ring 7. In this way, two upper and lower convex rings can be formed by multiple rolling, and the annular groove 4 is formed between the convex rings. The manufacturing is simple, and this ring body 3 can be used for more materials.

[0025] The main ring 5, the top inner ring 60 and the top outer ring 6 are fixed in sequence. In this way, the structure is stable.

[0026] The main ring 5, the bottom inner ring 70 and the bottom outer ring 7 are fixed in sequence. In this way, the structure is stable.

[0027] The filter cloth 2 is rolled outward or inward from the opening 1 and fixed to form a hollow ring cavity 20, and the ring body 3 is arranged in the ring cavity 20. In this way, the ring body 3 can be firmly fixed at the opening 1 and well wrapped and protected.

[0028] The ring body 3 further comprises a metal ring 8, which is arranged in the ring cavity 20 and located inside the ring body 3. The metal ring 8 can further strengthen the strength of the opening 1.

[0029] It also includes a ring cloth strip 9, which is fixed to the bottom of the filter cloth 2. This can further strengthen the strength of the filter bag.

[0030] The fixing is a suture connection fixing, which is more suitable for the fixed connection of the filter cloth.

[0031] The ring body 3 is made of felt, which allows the ring body 3 to have elasticity and good strength.

[0032] Preferably, the filter cloth and the ring cloth strip 9 are made of felt.
