[0024] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0025] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0026] As Figures 1 - 3 shown, the present utility model provides a wear-resistant composite filter material, which includes a filter layer 1. Wear-resistant layers 4 are provided on both sides of the filter layer 1. The wear-resistant layer 4 is a nylon fiber woven layer. Isolation membranes 2 are adhesively connected to both sides of the filter net. The isolation membrane 2 is a waterproof and breathable membrane. The isolation membrane 2 is located between the two wear-resistant layers 4. The side of the isolation membrane 2 away from the filter layer 1 is in a wavy structure. By providing the wear-resistant layer 4 made of nylon fiber, it is possible to protect the outside of the filter layer 1, thereby further preventing the filter layer 1 from being worn, and further extending the service life of the filter layer 1 and improving the practicability of the filter layer 1. A convex strip 5 is fixedly connected to the surface of the isolation membrane 2. The convex strip 5 is fixedly connected to the filter layer 1. The cross-section of the convex strip 5 is trapezoidal. The convex strip 5 with a trapezoidal cross-section can improve the connection strength between the filter layer 1 and the isolation membrane 2, so that the isolation membrane 2 can be in close contact with the filter layer 1. A protective net 3 is adhesively connected to the side of the isolation membrane 2 away from the filter layer 1. The protective net 3 is a polyamide fiber woven net. The protective net 3 is fixedly connected to the wear-resistant layer 4. By providing the protective net 3, the protective net 3 made of polyamide fiber can greatly improve the strength of the filter layer 1 and prevent the filter layer 1 from being punctured and losing the filtering effect.

[0027] As Figures 1 - 3 shown, clamping strips 6 are fixedly connected to the surfaces of the two wear-resistant layers 4. The clamping strips 6 are rubber strips. The clamping strips 6 can prevent the sides of the filter layer 1, the isolation membrane 2, the protective net 3 and the wear-resistant layer 4 from warping and separating, thereby improving the connection tightness. A plurality of clamping bars 7 are fixedly connected to the inner wall of the clamping strip 6. The clamping bars 7 penetrate through the filter layer 1, the isolation membrane 2, the protective net 3 and the wear-resistant layer 4. After the clamping bars 7 pass through the filter layer 1, the isolation membrane 2, the protective net 3 and the wear-resistant layer 4, the firmness between the clamping strip 6 and the wear-resistant layer 4 can be improved. A convex block 8 is fixedly connected to the position of the clamping strip 6 relative to the clamping bar 7. The convex block 8 can facilitate grasping the position of the clamping bar 7, so that the clamping bar 7 can be avoided when cutting the filter layer 1, facilitating the cutting operation.

[0028] The overall working principle is as follows. By setting the isolation film 2 made of waterproof and breathable membrane material on both sides of the filter layer 1, it can avoid the situation that the filter layer 1 is soaked and affects the normal air filtration of the filter layer 1. By setting the protective net 3, the protective net 3 made of polyamide fiber material can greatly improve the strength of the filter layer 1 and prevent the situation that the filter layer 1 is punctured and loses the filtering effect. The wear-resistant layer 4 can protect the outside of the protective net 3, thereby further preventing the situation that the filter layer 1 is worn. The convex strip 5 with a trapezoidal cross-section can improve the connection strength between the filter layer 1 and the isolation film 2, so that the isolation film 2 can be in close contact with the filter layer 1. The clamping strip 6 can prevent the sides of the filter layer 1, the isolation film 2, the protective net 3 and the wear-resistant layer 4 from warping and separating, thereby improving the tightness of the connection. After the clamping strip 7 passes through the filter layer 1, the isolation film 2, the protective net 3 and the wear-resistant layer 4, it can improve the firmness between the clamping strip 6 and the wear-resistant layer 4. The convex block 8 can facilitate grasping the position of the clamping strip 7, so that the clamping strip 7 can be avoided when cutting the filter layer 1, which is convenient for the cutting operation.
