Abstract

The invention discloses a reverse spiral coal distribution device of a chain-grate boiler. The reverse spiral coal distribution device comprises a coal bin and a variable speed motor, and is characterized in that a first auger and a second auger are arranged in the coal bin in parallel, wherein a first auger shaft of the first auger is provided with a spiral auger sheet; and a second auger shaft of the second auger is provided with a spiral auger sheet. According to the reverse spiral coal distribution device, the first auger is driven to rotate by the variable speed motor, and the second auger is driven to rotate, so that two groups of reversely arranged spiral auger sheets on each auger shaft rotate, and fire coal in a coal drop pipe is transferred and moved from the middle to the two sides and from the two sides to the middle for many times; and thus, the problems of coal aggregation and coal blockage are solved, coal briquettes and coal faces are fully mixed, a uniform coal layer is realized, the coal is more fully burned, and the coal saving effect is good.

Description

technical field [0001] The invention relates to a boiler feeding device, in particular to a reverse spiral coal distributing device used in a boiler coal bunker. Background technique [0002] Currently widely used coal-fired boilers, when the coal conveying system feeds coal into the coal bunker, the fuel coal enters the coal bunker by its own weight, because the large particles of coal are naturally piled up on both sides of the coal bunker, and the pulverized coal is concentrated in the coal bunker. In the middle part of the warehouse, the air supply to the grate is uneven, the air leakage on both sides of the grate is serious, the air volume in the middle part of the grate is insufficient, and the coal combustion in the boiler is insufficient, which reduces the utilization rate of fuel, causes serious waste of fuel, and improves the heating costs. [0003] In addition, the winter in the north is cold, and the coal has been frozen in the coal storage yard. When the coal e...
