Labyrinth type shot blast machine

Abstract

The invention provides a labyrinth type shot blast machine comprising a front chamber, a shot blasting chamber, a rear chamber, a conveying system and a material circulation system. The front chamber,the shot blasting chamber, the rear chamber, the conveying system and the material circulation system sequentially communicate. The conveying system comprises a conveying rail and a conveying motor.The conveying rail penetrates the front chamber, the shot blasting chamber and the rear chamber. The conveying motor is used for driving the conveying rail. The conveying motor is connected with the conveying rail. The front chamber is similarly in a Z shape and communicates with an inlet of the shot blasting chamber. The rear chamber is similarly in a Z shape and communicates with an outlet of the shot blasting chamber. The whole conveying rail located in the front chamber, the shot blasting chamber and the rear chamber is similarly in a U shape. The labyrinth type structure is adopted for the top of the shot blasting chamber. Twenty-four impeller heads are arranged in the shot blasting chamber. The front chamber, the shot blasting chamber and the rear chamber each communicate with a dustcollector through an air pipe. The dust collector is connected with a dust removal fan. The material circulation system is used for conveying shot materials, ejected by the impeller heads, back intothe impeller heads to be recycled.

Description

technical field [0001] The invention belongs to the field of shot blasting machines, and more specifically relates to a labyrinth type shot blasting cleaning machine. 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. 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-destructive te...
