Description

Technical Field

[0001] The utility model relates to the technical field of dust removal filter bags, in particular to a dust removal filter bag that prevents deformation. Background Art

[0002] A dust removal filter bag is a highly efficient dust removal filter material, which has good ventilation performance, high dust removal efficiency, and certain acid, alkali and heat resistance capabilities. Multilateral brushing is adopted during the weaving process, which improves the fabric thickness, is elastic, and has a very good dust removal effect. The dust removal rate can reach 99.999%. The dust removal filter bag is made of polyester staple fiber or long fiber as raw material, and its service life is generally 4-6 times that of glass fiber fabric. It has good air permeability, high dust collection rate, easy ash cleaning, and the dust removal efficiency can reach 98.99%.

[0003] However, for general dust removal filter bags on the market, when the temperature is relatively high during use, the dust removal filter bag is prone to deformation, resulting in a decline in filtration and dust removal performance. Moreover, when encountering larger particles during the filtration process, the impact force is relatively large, which not only affects the filtration and dust removal efficiency but also shortens the service life of the dust removal filter bag. Therefore, a dust removal filter bag that prevents deformation is proposed. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a dust removal filter bag that prevents deformation, and solves the problems in the above background art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] Preferably, elastic bands are arranged on the surface of the dust removal filter bag main body, and the number of the elastic bands is multiple groups.

[0008] Preferably, a limiting groove is formed on the surface of the fixing ring, and the limiting groove is arranged corresponding to the elastic band.

[0009] Preferably, a support block is fixedly installed inside the protection filter cylinder, and the support block is arranged in a fitting manner with the bottom surface of the rubber ring.

[0010] Preferably, a clamping groove is formed on the surface of the second protection plate, and the clamping groove is arranged corresponding to the clamping block.

[0011] Preferably, a threaded hole is formed inside the card slot, and the threaded hole is arranged corresponding to the fixing bolt.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: for the anti-deformation dust removal filter bag, through the arrangement of the elastic band and the limiting groove, the main body of the dust removal filter bag can be closely attached to the fixing ring, providing support for the main body of the dust removal filter bag to prevent deformation. Through the arrangement of the protective filter cylinder, the impact of gas on the main body of the dust removal filter bag can be reduced, and at the same time, larger particles in the filter species can be preliminarily filtered, avoiding the impact of larger particles on the main body of the dust removal filter bag and reducing the wear of the main body of the dust removal filter bag by larger particles.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment: Refer to Figures 1-5, the present utility model provides a technical solution, an anti-deformation dust removal filter bag, which includes a dust removal filter bag main body 1. A rubber ring 2 is fixedly installed on the top surface of the dust removal filter bag main body 1. A first protection plate 4 is arranged on the top surface of the rubber ring 2. A support rod 5 is fixedly installed on the bottom surface of the first protection plate 4. A fixing ring 6 is fixedly installed on the surface of the support rod 5. A clamping block 8 is fixedly installed on the surface of the first protection plate 4. A fixing bolt 9 is installed in the clamping block 8 by threading. A protection filter cylinder 10 is sleeved on the surface of the dust removal filter bag main body 1. A support block 11 is fixedly installed inside the protection filter cylinder 10, and the support block 11 is in close contact with the bottom surface of the rubber ring 2. Through the arrangement of the support block 11, the rubber ring 2 can be supported, which is convenient for the fixed installation of the dust removal filter bag main body 1. A second protection plate 12 is fixedly installed on the top surface of the protection filter cylinder 10.

[0021] Specifically, elastic bands 3 are arranged on the surface of the dust removal filter bag main body 1, and the number of the elastic bands 3 is multiple groups. A limiting groove 7 is opened on the surface of the fixing ring 6, and the limiting groove 7 corresponds to the elastic bands 3. Through the arrangement of the elastic bands 3 and the limiting groove 7, when installing the dust removal filter bag main body 1, the elastic bands 3 are sleeved on the surface of the dust removal filter bag main body 1, so that the limiting groove 7 limits the elastic bands 3, which can make the dust removal filter bag main body 1 closely fit on the fixing ring 6, provide support for the dust removal filter bag main body 1, and prevent deformation.

[0022] Specifically, a clamping groove 13 is opened on the surface of the second protection plate 12, and the clamping groove 13 corresponds to the clamping block 8. A threaded hole 14 is opened inside the clamping groove 13, and the threaded hole 14 corresponds to the fixing bolt 9. During installation, the clamping block 8 is placed into the clamping groove 13 to limit the first protection plate 4, and the fixing bolt 9 is rotated so that the fixing bolt 9 passes through the threaded hole 14, then the second protection plate 12 and the first protection plate 4 can be fixedly connected, thereby fixing the dust removal filter bag main body 1.
