Description
Technical field: [0001] The invention relates to a spiral coal feeder system, in particular to a variable frequency spiral coal feeder system, which belongs to the technical field of transmission machinery equipment. Background technique: [0002] At present, the coal blending and coal feeding equipment used in thermal power plants and coal mines generally use crank reciprocating type, impeller hanging type, buried scraper type and other structural forms of coal feeder; this type of coal feeder is not only heavy in structure , The power loss is large, and at the same time, because the coal is fed intermittently, it will cause a certain impact on the conveyor belt and the corresponding mechanical equipment, reducing the service life of the equipment. Due to the impact caused by sending coal at intervals, it will also generate relatively large noise, which will affect the surrounding environment and is not conducive to environmental protection. In addition, this type of equipm...
