Multi-coal special feeding device

Abstract

The invention discloses a multi-coal-species special feeding device, and belongs to the field of coal material blending combustion feeding devices. A flow dividing plate is arranged in a coal bin. The two ends of the flow dividing plate are fixed to the side wall of the coal bin. Four discharge ports are formed in a bottom plate of the coal bin. Two of the discharge ports are located below the flow dividing plate, and the other two discharge ports are located in the two sides of the flow dividing plate. The lower portion of each discharge port is connected with a coal discharge pipe. The bottom ends of the four coal discharge pipes are communicated. Gate doors are arranged between the discharge ports in the two sides of the flow dividing plate and the coal discharge pipes. A rotary cutting body is arranged in the coal bin and comprises a base body and three cutters symmetrical about the center of the base body. A power system is arranged below the center of the bottom plate of the coal bin and connected with the center of the base body. The multi-coal-species special feeding device is simple in structure, electrical parts are all arranged on the periphery of a body, and the cutters can be overhauled and replaced conveniently and rapidly through a channel below the flow dividing plate by opening an overhaul door.

Description

technical field [0001] The invention belongs to the field of coal material blending and burning feeding devices, and in particular relates to a multi-coal special feeding device. Background technique [0002] Combined with my country's energy strategic plan and the status quo of energy supply, coal used for electricity is mostly added with sticky coal and other raw coal with low calorific value to supply boilers. Due to the physical characteristics of sticky coal that is easy to stick, the raw coal is easy to adhere to the inner wall of the coal bunker during the coal supply operation, and the raw coal is easy to agglomerate itself or with the surrounding raw coal. The existing feeding device basically adopts the coal bunker to feed the material. Under the action of gravity, the coal flow is easy to cause stacking pressure and confluence, resulting in dense coal seam. As a result, the phenomena of coal shedding and coal blocking frequently occur during the transportation pro...

The existing feeding device basically adopts the coal bunker to feed the material. Under the action of gravity, the coal flow is easy to cause stacking pressure and confluence, resulting in dense coal seam. As a result, the phenomena of coal shedding and coal blocking frequently occur during the transportation process, resulting in poor operation of the generator set. Stable, affecting the normal coal output and economical operation of the unit
