Problems solved by technology

[0004] Purpose of the invention: The present invention provides a new generation of V-shaped wire industrial filter screen with higher welding strength, more accurate screen gap precision and more reasonable structure, and at the same time provides a new laser processing technology for the screen. The purpose is to Solve the problems of insufficient flatness of the filter screen and large error of mesh gap precision in the past, and the previous filter screen welding process consumes a lot of energy, the quality of solder joints is unstable, the error of mesh gap accuracy is not easy to control, and it cannot be used on a large flat V-shaped wire mesh And the application problems in the production of large-diameter V-shaped wire mesh cylinders

[0038] detailed description: The present invention will be further described below in conjunction with accompanying drawing:

[0039] Such as figure 1 As shown, the present invention provides a V-shaped silk industrial filter screen, which includes a support frame 1 and a filter wire 2 with a triangular cross-section, and the axis directions of the support frame 1 and the filter wire 2 are formed perpendicular to each other. Figure 9 The staggered net structure shown; the support frame 1 is a toothed structure with a "V'-shaped tooth groove 3, and one corner of the filter wire 2 is inserted into the tooth groove 3 to mesh with the tooth groove 3 to form a whole.

[0040] The support frame 1 is figure 1 straight support frame as shown or as figure 2 and 3 The circular support frame shown.

[0041] The filter wire 2 meshes with the tooth slots 3 of the straight support frame to form a flat filter screen or the filter wire 2 meshes with the tooth slots 3 of the circular...

Abstract

The invention provides an industrial filter screen with V-shaped wires. The filter screen comprises a supporting frame and filter wires of which the cross sections are triangles, wherein the supporting frame is vertical to the axial direction of the filter wires to form a stagger net structure; the supporting frame is a tooth-shaped structure with V-shaped tooth troughs; and a corner of each filter wire is inserted into the tooth troughs to engage with the tooth troughs to form a whole. The laser processing process can realize higher welding quality stability and guarantee uniform gap intervals and better surface evenness.

Description

technical field [0001] The invention relates to a V-shaped wire mesh widely used in the field of industrial filtration and a preparation process thereof, in particular to a V-shaped wire industrial filter manufactured by laser cutting and welding and a laser processing technology thereof. Background technique [0002] The wire mesh woven by metal wire is widely used in the domestic traditional filtration industry. Due to the large contact area between solid particles (catalysts, molecular sieves and various filter materials) and the screen, the particles are easy to clog and bend after being pressed, resulting in expensive media loss, and even make the device inoperable and difficult to maintain. [0003] In order to solve the above technical problems, Australia's Johnson company and Belgium's Trislot company have developed and manufactured a V-shaped wire mesh. The processing technology of this kind of mesh first adopts the method of extrusion and drawing to obtain various...
