Meshed belt type shot-blast cleaning machine

Abstract

The invention relates to a meshed belt type shot-blast cleaning machine. The meshed belt type shot-blast cleaning machine comprises a shot-blast cleaning chamber and a meshed belt conveying system, wherein a shot separator is arranged above the shot-blast cleaning chamber; at least eight shot blasters which are pointed to shot-blasting stations are mounted on the shot-blast cleaning chamber in pairs; four shot blasters are arranged on the sidewall of the shot-blast cleaning chamber above the shot-blasting station, the other four shot blasters are arranged on the sidewall of the shot-blast cleaning chamber below the shot-blasting station, and the eight shot blasters are arranged in bilateral symmetry along the conveying direction of the meshed belt conveying system; the shot blasters are mounted obliquely, an included angle between the shot blasters located above the shot-blasting stations and the horizontal plane where the shot-blasting stations are located is alpha, an included angle between the shot blasters located below the shot-blasting stations and the horizontal plane where the shot-blasting stations are located is beta, and the included angles respectively meet the conditions that the alpha is not smaller than 15 degrees and not greater than 25 degrees and the beta is not smaller than 30 degrees and not greater than 40 degrees. The meshed belt type shot-blast cleaning machine can be used for carrying out shot-blasting treatment on a steel strip on the shot-blasting station from all angles and is high in efficiency and good in cleaning effect.

Description

technical field [0001] The invention relates to a surface treatment device for workpieces, in particular to a mesh belt type shot blasting cleaning machine. Background technique [0002] The mesh belt shot blasting machine puts the workpiece on the mesh belt, and the conveying mesh belt transports the workpiece forward. When the workpiece enters the cleaning room, the shot blaster starts to work in order to clean the workpiece. After the shot blasting treatment, the scale, dirt and other attachments on the surface of the workpiece are cleaned, and a smooth and uniform roughness surface can be obtained, and the treated surface can reach Sa2-2.5 level. The working method of the mesh belt shot blasting machine is a continuous cycle, which can fully improve production efficiency. The pellets thrown by the shot blasting machine are collected and processed by the circulation processing system, and continue to be used by the shot blasting machine. [0003] In the prior art, the m...
