Abstract
Description
Technical Field
[0001] This utility model belongs to the field of filter bag technology, specifically a wear-resistant dust removal filter bag. Background Technology
[0002] Dust collector filter bags are a type of high-efficiency dust collection filter material. They are made from raw materials such as polyester staple fiber, PPS fiber, PP polypropylene, aramid fiber, and acrylic fiber. Their service life is generally 2-4 years. They have good air permeability, high dust collection rate, are easy to clean, and the dust removal efficiency can reach 98.99%.
[0003] Wear-resistant dust collector filter bags intercept particulate matter in dust-laden airflow through the porous structure of the filter material surface. At the same time, the wear-resistant material reduces the loss caused by dust erosion and friction, achieving efficient dust removal and long-term stable operation.
[0004] Traditional filter bags are mostly single-layer structures. Under the continuous impact and friction of high-concentration, high-hardness dust, they are prone to surface damage and thinning, resulting in a decrease in filtration efficiency or even premature failure. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a wear-resistant dust collector filter bag.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The wear-resistant dust collector filter bag of this utility model includes a filter bag body, the filter bag body includes a mesh material layer woven from high-hardness and high-wear-resistance ceramic fibers and metal wires, an elastic buffer layer made of polyurethane foam material is fixedly connected to the inner side of the mesh material layer, a high-efficiency filter layer is fixedly connected to the inner side of the elastic buffer layer, and a skeleton body is fixedly connected to the inner side of the high-efficiency filter layer.
[0007] Preferably, the skeleton body includes a plurality of polygonal skeleton rings.
[0008] Preferably, the corners of the polygonal skeleton ring are designed with rounded transitions.
[0009] Preferably, several polygonal skeleton rings are fixedly connected to several vertical skeletons in a ring array.
[0010] Preferably, the outer side of the polygonal skeleton ring is fixedly connected to the inner side of the high-efficiency filter layer.
[0011] Preferably, the outer side of the vertical frame is fixedly connected to the inner side of the high-efficiency filter layer.
[0012] Preferably, an mounting ring is fixedly connected to the top of the vertical frame.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. The wear-resistant dust collector filter bag of this utility model uses a mesh material layer woven from high-hardness, high-wear-resistant ceramic fibers and metal wires to directly resist the impact and friction of dust; the middle layer is an elastic buffer layer made of polyurethane foam material, which can absorb the energy of dust impact and reduce damage to the inner layer of the filter bag; the inner layer is a high-efficiency filtration layer, which ensures the filtration effect while reducing wear due to the protection of the outer and middle layers.
[0015] 2. The wear-resistant dust collector filter bag of this utility model replaces the traditional circular support frame with a polygonal frame ring. The corners of the frame are designed with rounded transitions. The polygonal structure allows the filter bag to be subjected to more uniform force during filtration and dust removal, reducing wear caused by local stress concentration and increasing the stability of the filter bag.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figures 1 to 4As shown in the embodiment of this utility model, the wear-resistant dust collector filter bag includes a filter bag body 1. The filter bag body 1 includes a mesh material layer 11 woven from high-hardness and high-wear-resistance ceramic fibers and metal wires. An elastic buffer layer 12 made of polyurethane foam material is fixedly connected to the inner side of the mesh material layer 11. A high-efficiency filter layer 13 is fixedly connected to the inner side of the elastic buffer layer 12. A skeleton body 2 is fixedly connected to the inner side of the high-efficiency filter layer 13.
[0025] The filter bag body 1 reduces wear. During use, the mesh material layer 11, woven from high-hardness and high-wear-resistant ceramic fibers and metal wires, can directly resist the impact and friction of dust. The middle layer is an elastic buffer layer 12, made of polyurethane foam material, which can absorb the energy of dust impact and reduce damage to the inner layer of the filter bag. The inner layer is a high-efficiency filter layer 13, which ensures the filtration effect while reducing wear due to the protection of the outer and middle layers.
[0026] The traditional circular support frame is replaced with a polygonal frame ring 21. The edges and corners of the frame are designed with rounded transitions. The polygonal structure allows the filter bag to be subjected to more uniform force during filtration and dust removal, reducing wear caused by local stress concentration and increasing the stability of the filter bag.
[0027] like Figure 5 As shown, the skeleton body 2 includes several polygonal skeleton rings 21. The corners of the polygonal skeleton rings 21 are designed with rounded transitions. Several polygonal skeleton rings 21 are fixedly connected to several vertical skeletons 22 in a ring array. The outer side of the polygonal skeleton rings 21 is fixedly connected to the inner side of the high-efficiency filter layer 13. The outer side of the vertical skeletons 22 is fixedly connected to the inner side of the high-efficiency filter layer 13. An installation ring 3 is fixedly connected above the vertical skeletons 22.
[0028] Working principle: The filter bag body 1 can reduce wear. During use, the mesh material layer 11, which is woven from high-hardness and high-wear-resistant ceramic fibers and metal wires, can directly resist the impact and friction of dust. The middle layer is an elastic buffer layer 12, which is made of polyurethane foam material. It can absorb the energy of dust impact and reduce damage to the inner layer of the filter bag. The inner layer is a high-efficiency filter layer 13. While ensuring the filtration effect, it can reduce wear due to the protection of the outer and middle layers.
[0029] The traditional circular support frame is replaced with a polygonal frame ring 21. The edges and corners of the frame are designed with rounded transitions. The polygonal structure allows the filter bag to be subjected to more uniform force during filtration and dust removal, reducing wear caused by local stress concentration and increasing the stability of the filter bag.
