Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of composite screens, in particular to a wave-shaped punched composite screen. Background Art
[0002] Perforated screen plates, as a medium for traditional screening materials, were once widely used on vibrating screens. However, with the development of wear-resistant materials such as polyurethane, rubber and ceramics, single stainless steel perforated screen plates have been difficult to meet market needs; polyurethane has become another development trend by combining with metal to form composite screen plates due to its own fluidity and diversified casting products. Among them, composite screen plates combining perforated steel plates and polyurethane are widely used in the market due to their advantages such as convenient installation and disassembly, diverse installation styles, good screen strength and long service life. Due to its modular installation method, there is a certain area of blind spots, which partially affects the screening efficiency.
[0003] The existing technology has the following problems:
[0004] After searching, Chinese Patent Publication No.: CN218133277U discloses a new type of polyurethane screen, which includes a plurality of screen splits detachably mounted on a screen frame, the mounting end of the screen frame is fixedly connected with a baffle, the screen split includes a base, a surface layer arranged on the working surface of the base, the color of the surface layer is different from the color setting of the base, the screen frame includes a U-shaped support main frame, a plurality of transverse ribs arranged on the U-shaped support bracket, and vertical ribs vertically connected to the transverse ribs, and a limiting groove is provided on the transverse ribs. The screen split also includes a slider slidably engaged with the limiting groove. The patent adopts a splicing structure, which can partially replace damaged screen splits, reducing the cost of use, and can more intuitively understand the degree of wear of the screen splits, avoiding excessive wear without detection, and is easy to use.
[0005] However, the above patent still has problems that need to be improved during actual use. The most obvious one is that when the material is climbing the slope, the retention time of the material on the screen surface needs to be extended, which makes it difficult to fully screen the material, thereby reducing the screening efficiency.
[0006] To this end, we proposed a wave-shaped punched composite screen to solve the above-mentioned drawbacks. Utility Model Content
