Shot blasting machine cleaning device and method

Abstract

The invention relates to the technical field of shot blasting machines, and discloses a shot blasting machine cleaning device which comprises a cleaning chamber. The inner walls of the front and rearopposite sides of the cleaning chamber are fixedly connected with one same conveying roller through a plurality of supporting rods, and the left and right opposite sides of the cleaning chamber are each provided with a material opening for the conveying roller to penetrate through and extend out; and an electromagnetic cleaning mechanism, an air blowing cleaning mechanism and a scraping cleaning mechanism are fixedly arranged on the inner wall of the top of the cleaning chamber in sequence from left to right. The shot blasting machine cleaning device and method have the advantages that the surface of a steel plate can be quickly and deeply cleaned in all directions through the three stages of cleaning mechanisms, the cleaning efficiency and quality are improved, and subsequent production and use of the steel plate are guaranteed.

Description

technical field [0001] The invention relates to the technical field of shot blasting machines, in particular to a cleaning device and method for shot blasting machines. Background technique [0002] Shot blasting machine is a shot blasting equipment that uses high-speed projectiles thrown by a shot blaster to clean or strengthen the surface of castings. The shot blasting machine can shake out sand, remove core and clean the casting at the same time. [0003] Shot blasting equipment is firstly used to remove sand and scale on the surface of cast steel and iron castings in the foundry industry. Almost all steel castings, gray castings, malleable steel parts, ductile iron parts, etc. must be shot blasted. This is not only to remove scale and sticky sand on the surface of the casting, but also an indispensable preparation process before the quality inspection of the casting. For example, the casing of a large gas turbine must be subjected to strict shot blasting before non-des...

AI Technical Summary

Problems solved by technology

[0004] During the operation of the shot blasting machine, the projectile collides with the outer wall of the steel plate, so that the scale on the surface of the steel plate is separated from the steel plate. However, when the steel shot impacts the steel plate, the edge of part of the scale is lifted and still attached to the steel plate. , affect the post-processing of the steel plate, and some shot particles will remain on the surface of the steel plate after removing the iron oxide scale on the surface of the steel plate. It is easy to be pressed into the surface of the steel plate to form defects, which directly affects the surface quality of the shot blasted steel plate
