Shot blasting machine with shot circulating system

Abstract

The invention provides a shot blasting machine with a shot circulating system. The shot blasting machine comprises a shot blasting box and an impurity removing device arranged on one side of the shot blasting box. A dredging device is arranged below the first screen, the dredging device comprises a dredging piece and a driving piece, a check block is fixedly arranged in the protection box, and the dredging piece is elastically connected with the check block; the two sets of dredging pieces are arranged and arranged under the first screen, the driving pieces are symmetrically arranged on the inner walls of the two sides of the protection box, and the driving pieces are in transmission connection with the dredging pieces; the driving piece drives the two groups of dredging pieces to move alternately; impurities clamped in meshes of the first screen are sequentially removed, in the cleaning process, half of the area of the first screen is always in a working state, and shot blasting and impurities can still be separated; and the grid net is bounced under the action of the jacking spring, so that the grid net impacts the first screen net, and the flat impurities which are not easy to roll are bounced by vibration and slide out along the first screen net.

Description

technical field [0001] The invention relates to the field of shot blasting machines, in particular to a shot blasting machine with a pellet circulation system. Background technique [0002] Shot blasting machine is a processing technology that throws steel grit and steel shot on the surface of material objects at high speed through a shot blasting machine; compared with other surface treatment technologies, it is faster and more effective, and can partially retain or punch Post casting process; shot blasting machines can also be used to remove burrs, diaphragms, and rust that may affect the integrity, appearance, or definition of parts of an object; shot blasting machines can also target a partially coated surface to remove surface contaminants, And provide a surface profile that increases the adhesion of the coating to achieve the purpose of strengthening the workpiece; [0003] The existing shot blasting machine with a shot blasting circulation system generally removes im...

AI Technical Summary

Problems solved by technology

[0003] The existing shot blasting machine with shot blasting circulation system generally removes impurities such as welding slag, rust and shot blasting debris in the shot blasting through the drum screen. In the actual use process, there are too many impurities in the drum screen. Blocking the sieve holes will affect the shot blasting sieving; due to the special structure of the roller sieve, the mesh of the roller sieve can only be cleaned after use, and it is easy to cause the shot blasting to fail to pass through the sieving process. Shot blasting is discharged with impurities, resulting in a large amount of shot blasting being wasted
