Novel safety filter net

Abstract

The invention discloses a novel safety filter net. The novel safety filter net comprises an outer mesh frame and an inner mesh frame. The outer mesh frame comprises an outer border and multiple supporting beams. The supporting beams are fixed to the inner wall of the outer border. The mesh structures of the supporting beams are matched with the inner mesh frame. The inner mesh frame comprises multiple cross beams and vertical beams. Multiple connecting rods are arranged on the periphery of the inner mesh frame. Multiple fixing buckles are arranged on the outer border. The connecting rods are connected with the fixing buckles. Grooves are formed in the supporting beams. The cross beams and the vertical beams of the inner mesh frame are connected with the interiors of the supporting beams. The problem that safety meshes need to be wholly replaced can be solved, the safety meshes can be quickly replaced under the condition that normal production operation is not affected, operation is easy and convenient, the bearing capacity of the meshes is enhanced, the service life of the meshes is effectively prolonged, production efficiency is improved, and energy can be saved while economic benefits are increased.

Description

technical field [0001] The invention belongs to the field of building material processing, in particular to a novel safety filter net. Background technique [0002] In the field of construction, the safety grid is an important protective channel facility for the conveyor belt to send sand and gravel aggregates into the mixer. During normal daily production, a large amount of sand and gravel aggregates pass through the safety grid. The materials required by the building are filtered out, while ensuring that the materials are evenly stirred. The traditional safety grid is made by welding ordinary flat steel on the side panels around the waiting tank. Because a large amount of sand and gravel aggregates pass through this grid, the flat steel is worn out. Soon, the replacement cycle is short, production needs to be stopped during replacement, and on-site welding production affects normal production and greatly prolongs maintenance time. At the same time, due to the installation ...

[0002] In the field of construction, the safety grid is an important protective channel facility for the conveyor belt to send sand and gravel aggregates into the mixer. During normal daily production, a large amount of sand and gravel aggregates pass through the safety grid. The materials required by the building are filtered out, while ensuring that the materials are evenly stirred.

Because a large amount of sand and gravel aggregates pass through this grid, the flat steel is worn out. Soon, the replacement cycle is short, production needs to be stopped during replacement, and on-site welding production affects normal production and greatly prolongs maintenance time. At the same time, due to the installation cost of the safety grid and the difficulty of welding, at the same time, due to the continuous contact between the sand and gravel and the safety net grid contact, causing the safety grid to deform easily while under pressure
