SHOT-BLASTING DEVICE Russian patent published in 2011 - IPC B24C5/00 B24C7/00 B24C9/00 

FIELD: process engineering.

SUBSTANCE: invention relates to machine building. Proposed device comprises housing with slit-like valve, shot collection bin with intake hose, transfer gas feed and pressure equalising pipelines, proportioner with locking rod, pipeline to feed shots into processing zone and extra pipeline to feed transfer gas. Slit-like valve consists of fixed part representing a disk with slit-like cutouts and moving part arranged to turn. Aforesaid case consists of cylindrical and conical parts. Slit-like valve moving part features cylindrical shape and accommodates elastic element. One end of the latter thrust against bottom with slit-like cutouts and opposite ends thrusts against tight cover with extra pipeline connection hole. Case cylindrical part has through horizontal slot accommodating handle secured on lateral surface of slit-like valve moving part. Shots collection bin has one observation port. End of pipeline feeding shots into processing zone is widened.

EFFECT: simplified design.
