Device and method for cleaning shot blasting machine

Abstract

The invention discloses a device and a method for cleaning a shot blasting machine. The device for cleaning the shot blasting machine comprises a shot blasting cleaning chamber, a longitudinal conveying auger, a bucket type elevator, a transverse conveying auger and a cleaning device, wherein the outer wall of the shot blasting cleaning chamber is provided with a plurality of shot blasting devices; one end of the longitudinal conveying auger is connected with a shot material outlet of the shot blasting cleaning chamber; the bucket type elevator is provided with a feed port and a discharge port; one end of the transverse conveying auger is connected with the discharge port of the bucket type elevator; the cleaning device comprises a scraping plate device, a paint rolling device and a shot blowing device; the distances between the scraping plate device, the paint rolling device and the shot blowing device are larger than or equal to 50mm and smaller than or equal to 1200mm. The device and the method aim at the problem existing in steel plate shot blasting equipment in the existing industry, and a novel three-pass cleaning device is adopted for ensuring that cleaned steel plates are free of scattered steel shots and dust.

Description

technical field [0001] The invention relates to a shot blasting equipment and a method for cleaning a thin plate by using the equipment, in particular to a shot blasting machine cleaning device and method. 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 t...

AI Technical Summary

Problems solved by technology

[0005] (1) The steel plate workpieces thrown by the steel plate shot blasting machine currently used in the shot blasting machine industry, because the requirements of the steel plate shot blasting machine are much higher than those of ordinary shot blasting machines, it can be clearly seen on the discharge roller table There are scattered steel sand and dust, which cannot meet the requirements of the next painting process;

[0006] (2) The cleaning device used on the steel plate shot blasting machine has a low degree of automation, and the operator has to manually lift up and down according to the thickness of the workpiece; the precision is low, and it is easy to cause the steel plate workpiece to be stuck;

[0007] (3) The arrangement positions of the scraper device, rolling brush device and blasting device in the cleaning device of most steel plate shot blasting machines are all made according to the experience of the production workers, there is no theoretical data, and there is no design of the width of the shot blasting steel plate according to the needs The distance between the above three cleaning devices, so the cleaning effect is often not up to the due requirements
