METHOD OF DUST GENERATING EQUIPMENT ASPIRATION AND SYSTEM FOR ITS REALISATION Russian patent published in 2008 - IPC B65G53/24 

FIELD: technological processes.

SUBSTANCE: collector-header is used, which is arranged as tapered, installed vertically with its top downwards with creation of pressure difference in it to the lower side from the initial one. At that large fractions of dust settle down under effect of gravitation forces and self-flow to technological tank through return pipeline, which is connected with tapered collector-header and technological tank. Small fractions of dust together with air are supplied through air duct and transport manifold for filtration. According to invention, in system that realised the method, by means of the first outlet through the top oriented downwards, collector-header is connected by return pipeline with technological tank, at that with its second outlet collector-header is connected with air duct to transport manifold connected to filter.

EFFECT: simplification of aspiration process.
