Abstract

A coal bunker for preventing high-moisture coal from sticking according to the present invention includes a coal bunker body, the coal bunker body is a quadrangular pyramid with a wide top and a narrow bottom, and the upper and lower ends of the coal bunker body are open structures. One side of the coal bunker body is an inclined surface, and the other three sides are vertical surfaces. The inclined surface of the coal bunker body and the vertical surface opposite to the inclined surface are provided with loose parts that slide along the inner wall. On the inner wall of the main body, there is a toggle piece, which is provided with a pull rod extending outward through the coal bunker body. The outer wall of the coal bunker body is provided with a drive motor, and the output shaft of the drive motor The connecting rod is connected with the end of the pull rod away from the toggle piece. The vertical surface can accumulate the coal in the coal bunker body to the inclined surface, reducing the surface that the coal can adhere to, and then the loose part is moved by the toggle part to loosen the coal bonded on the inner wall of the coal bunker body and recover The fluidity of the coal prevents the operation of the boiler from being disturbed by coal blockage.

Description

technical field [0001] The invention belongs to the field of power generation equipment, in particular to a coal bunker for preventing high-moisture coal from caking. Background technique [0002] The moisture content of coal has a great influence on the fluidity of coal. Within a certain range, the higher the moisture content of coal, the greater the viscosity and the worse the fluidity. Circulating fluidized bed boilers generally require the coal moisture to be controlled between 6% and 8%. When the coal moisture exceeds 8%, the viscosity will increase greatly; when the coal moisture exceeds 10%, the coal fluidity will reduce the viscosity. Increased, it is easy to accumulate on the wall of the coal bunker due to adhesion and adsorption. Coal-based thermal power generation is mainly washed and mixed coal. The moisture content of this coal type is about 14%. After blending with other coal types, the boiler will carry out mixed combustion. After the proportioning, the moist...
