rotary valves, and, particulate withers concentration transport system

摘要

High concentration particulate withers concentration transport system powder particles from the container to the storage device Transport. Rotary valve (103) for continuously supplying the granules from the container to transport pipe (102). Compressor, and by feeding the gas into the space (312, 313) between the side plate of the wall side of the rotor in the rotary valve (103) and (303, 304) the casing (201) (308, 309), transport tube (102 We discourage the intrusion of particulate material to the space from). The interior of the rotary valve is divided into a plurality of small spaces (212) by a plurality of blades (211). The side wall of the rotor, by causing the outer peripheral surface contacting with the inner circumferential surface of the gasket (306), separating said plurality of small spaces (212) from said space (312, 313). In each of the small space (212), an inner peripheral surface and outer peripheral surface portions adjacent to the area in contact of the side walls of the rotor, cutting to particulate material can be circulated out portion of the gasket (306) ( 314) is provided.
