BELT FEEDER MANUFACTURING OPTIMIZATION METHOD Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: invention can be used for uniform and continuous delivery of lump and loose materials of shelf from hopper into fuel installations of domestic or defense applications. According to proposed method, endless belt is mounted on tension and drive drums with tensions of belt to hold material on support rotary rollers from port of hopper tom discharge port. Tension and drive drums are brought into interaction with output shaft of drive which is set for discrete feeding of endless belt, material is carried by endless belt resting on support rotary rollers from port of hopper to discharge port, lower profile of nonworking section of endless belt is arranged in dynamic opposite to working section of endless belt at minimum distance from each other in zone of border sections of charging and section of vulcanization, and unit of tensions section and drive section are made in feeder as extreme ones and enclosed in common outer housing of belt feeder in which intake flange is made. Tensioning of endless belt is carried out at butt joining of end sections of endless belt and is correlated to temperature of its heating in vulcanization section, and tight seals of statically motionless butt joints increase action onto interconnected contact surfaces of endless belt. Carried material and/or articles in vulcanization section are heated to vulcanization temperature by delivering energy to heating device. Proposed method provides practically new possibilities of use of feeder for different purposes with quick readjustment of technological processes in different industries, particularly, processing of coal, rubber articles from vulcanized rubber to ready made article and for other purposes in industrial production. Along with high capacity of proposed feeder it guarantees high quality of product and safety of personnel engaged in production.

EFFECT: improved economy and provision of high capacity.
