Problems solved by technology

[0002] China is a big mining country, but at present, all kinds of mineral processing enterprises in China are still relatively backward, and they do not have sufficient understanding of the importance of screens in the mineral processing industry. With the rapid development of new materials and new processes, ideas continue to innovate, and global washing The industry screen is undergoing an innovation. The traditional manganese steel screen, punching screen, steel wire woven screen and stainless steel screen have large noise, poor wear resistance, heavy screen and heavy equipment load in the mineral processing process. , Large maintenance, low equipment operation efficiency, high production cost, poor comprehensive economic efficiency and other defects, polyurethane screen products have wear resistance, oil resistance, aging resistance, tear resistance, impact resistance, high elasticity, strong shock absorption and load support capacity Great performance, compared with its metal screen, its polyurethane screen has light weight, high screening efficiency, no hole blocking, anti-friction, impact resistance, tear resistance, long life, low noise, convenient installation, high comprehensive benefits, etc. advantage

Embodiment Construction

[0023] A tensioned screen comprising a tensioning hook 1, a steel wire rope 2, a cold-drawn steel wire 3, polyurethane 4, and a screw 5. There are tensioning hooks 1 at both ends of the tensioning screen, the steel wire rope 2 and the tensioning hook 1 Connect with screws 5 to form the skeleton layer of the polyurethane screen. The steel wire rope 2 is embedded perpendicular to the tension hook 1. The cold-drawn steel wire 3 is vertically arranged between the steel wire rope 2. After the skeleton is processed, the polyurethane material liquid is poured. A polyurethane mesh layer is formed to make a tensioned screen.

[0024] A production process of a tensioned screen comprising the following steps:

[0025] (1). Fabrication of the skeleton. The skeleton includes tension hooks, steel wire ropes, cold-drawn steel wires, and screws. The manufacturing steps include the following:

[0026] .Prepare the tensioning hook, cut it into the required length with metal lath, bend one en...

Abstract

A tension type screen comprises tension hooks, a steel wire rope, cold-drawn steel wires, polyurethane and screws. A production technology of the tension type screen comprises the steps of skeleton fabrication, treatment of abrasive blasting, degreasing and coating on a skeleton, mold preparation, detection and correction of a formula, screen pouring, demolding, repairing, inspection and finished product packing. The tension type screen has the advantages of being resistant to abrasion, oil, aging, tear and impact, high in elasticity, strong in shock absorption, large in load support capacity and the like; compared with a metal screen, a polyurethane screen is light in weight, high in screening efficiency, not prone to hole blocking, resistant to abrasion, impact and tear, long in service life, low in noise, convenient to install and high in comprehensive benefits.

Description

technical field [0001] The invention relates to the technical field of chemical rubber and plastics, in particular to a tensioned screen and a production process.
