Flexible rubber surface composite screen with supporting net and forming method thereof

Abstract

The invention discloses a flexible rubber surface composite screen with a supporting net and a forming method thereof, and solves the problems that an existing device blocks holes, is not wear-resistant and is short in service life. The flexible rubber surface composite screen is characterized by comprising a frame body, a screening area and the supporting net; the frame body comprises a metal framework and a polyurethane coating layer; the screening area is formed by punching a flexible rubber plate; the supporting net is of a net-shaped structure formed by weaving warps and wefts through steel wire rope core polyurethane bars in a vertically and horizontally interwoven mode; and the punched rubber screen surface and the metal framework with the woven supporting net are subjected to secondary pouring together in a mold, the framework and the flexible rubber screen surface are connected into a whole through the polyurethane coating layer, and a finished product is obtained through secondary curing. According to the flexible rubber surface composite screen with the supporting net and the forming method thereof, the flexible rubber screen surface, the polyurethane bar supporting net, the metal framework, the polyurethane coating layer and the like are arranged, so that the problem of hole blocking and pasting of fine-fraction materials in a wet and sticky state can be effectively solved, the screening efficiency of the materials under the wet and sticky condition is effectively improved, the labor and maintenance cost is saved, and the production halt loss is reduced.

Description

technical field

[0001] The invention relates to a material screening tool, in particular to a flexible rubber surface composite screen with a supporting net and a forming method thereof. Background technique

[0002] In coal mines, chemical industry, building materials, metallurgy and other fields, due to the need for material classification, screens are widely used. Traditional screens are mostly metal screens. In recent years, due to the application of new materials and technologies, rubber polyurethane screens with high wear resistance, long life, low energy consumption and high screening efficiency have been promoted and widely welcomed. In the process of material screening under some special working conditions, the phenomenon of material clogging the screen mesh often occurs, especially in the screening process of fine-grained materials, the screening requirements are high, and the corresponding screen mesh is small , The plugging phenomenon is more obvious and common....
