Description

Technical Field

[0001] The utility model belongs to the technical field of filter press crush resistant structure, in particular to a filter press crush resistant structure. Background Art

[0002] The crush-resistant structure of filter press usually refers to the crush-resistant structure design of the filter plate of the filter press. This structure can increase the pressure resistance of the filter press, allowing the filter press to operate at higher pressure and improve the filtration efficiency. The specific structural details may vary depending on the filter press model and manufacturer, but generally speaking, this crush-resistant structure involves the following aspects: material selection, structural design, edge treatment and processing technology. In short, the crush-resistant structure of filter press is a structure specially designed to improve the pressure resistance and filtration efficiency of the filter press. In actual application, it is necessary to select a suitable filter press and crush-resistant structure according to different working conditions and usage requirements. The problem with the existing technology is that when a large flow of oil enters the cavity, it will directly impact the filter paper, which will cause the filter paper to deform or even rupture over a long period of time, thereby affecting the use of the structure. Utility Model Content

[0003] In response to the problems existing in the prior art, the utility model provides a filter press crush-resistant structure, which has the advantages of reducing the impact force of the oil entering the cavity and avoiding deformation of the filter paper. It solves the problem that when a large flow of oil enters the cavity, it will directly impact the filter paper, which will cause deformation or even rupture of the filter paper over a long period of time, thus affecting the use of the structure.

[0004] The utility model is realized in this way: a filter press crush resistant structure comprises an upper cover, glue, wire mesh, filter paper and a lower cover, wherein the glue is bonded to the bottom of the upper cover, the wire mesh is bonded to the bottom of the glue, and the lower cover is fixedly connected to the bottom of the wire mesh;

[0005] The wire mesh is divided into an inner layer and an outer layer, and the filter paper is arranged between the inner wire mesh and the outer wire mesh.

[0006] As a preferred embodiment of the utility model, the wire mesh is arranged in a curved shape at the bottom of the glue to form a cavity, and the filter paper is arranged inside the cavity. The surface of the filter paper is in close contact with the surface of the wire mesh. After the wire mesh and the filter paper are in close contact, the flow resistance can be reduced and the cost can be reduced.

[0007] As a preferred embodiment of the utility model, limiting feet are equidistantly fixedly connected to the four sides of the surface of the lower cover. By providing the limiting feet, the contact area between the lower cover and the installation position can be increased, thereby improving the stability of the lower cover.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] 1. The utility model uses an upper cover, glue, wire mesh, filter paper, a lower cover, and a cavity limit support leg in coordination. The impact force of the oil is reduced after passing through the curved wire mesh, thereby avoiding deformation and damage of the filter paper. This solves the problem that when a large flow of oil enters the cavity, it will directly impact the filter paper, which will cause deformation or even rupture of the filter paper for a long time, thus affecting the use of the structure.

[0010] 2. The utility model can increase the contact area between the lower cover and the installation position by providing the limiting support feet, thereby improving the stability of the lower cover. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0016] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0017] like Figures 1 to 3 As shown, a filter press crush resistant structure provided by an embodiment of the utility model comprises an upper cover 1, glue 2, wire mesh 3, filter paper 4 and a lower cover 5, wherein the glue 2 is bonded to the bottom of the upper cover 1, the wire mesh 3 is bonded to the bottom of the glue 2, and the lower cover 5 is fixedly connected to the bottom of the wire mesh 3;

[0018] The wire mesh 3 is divided into an inner layer and an outer layer, and the filter paper 4 is arranged between the inner wire mesh 3 and the outer wire mesh 3 .

[0019] refer to Figure 2 The wire mesh 3 is arranged at the bottom of the glue 2 in a curved shape to form a cavity 6 , and the filter paper 4 is arranged inside the cavity 6 , and the surface of the filter paper 4 is in close contact with the surface of the wire mesh 3 .

[0020] By adopting the above solution, the wire mesh 3 is in close contact with the filter paper 4, so that the flow resistance can be reduced and the cost can be reduced.

[0021] refer to Figure 1 The lower cover 5 is equidistantly and fixedly connected with limiting legs 7 around its surface.

[0022] By adopting the above solution, by providing the limiting legs 7 , the contact area between the lower cover 5 and the installation position can be increased, thereby improving the stability of the lower cover 5 .

[0023] The working principle of this utility model:

[0024] When in use, after the device is installed at a designated position, oil enters the cavity of the device and impacts the filter paper 4 in the wire mesh 3. At this time, the oil reduces its impact force after passing through the curved wire mesh 3, thereby avoiding deformation and damage of the filter paper 4.

[0025] In summary: the filter press crush-resistant structure, through the coordinated use of the upper cover 1, glue 2, wire mesh 3, filter paper 4, lower cover 5, and cavity 6 limiting legs 7, solves the problem that when a large flow of oil enters the cavity, it will directly impact the filter paper, which will cause the filter paper to deform or even rupture over a long period of time, thereby affecting the use of the structure.
