Abstract

The invention provides a dust overflow prevention system of a boiler coal feeder. The dust overflow prevention system comprises a coal feeder shell, a blanking point adjusting device is arranged at one end in the coal feeder shell, a conveying device is arranged at the other end in the coal feeder shell, a coal inlet pipe is fixed to the top end of the exterior of the coal feeder shell, a coal outlet pipe is fixed to the bottom end of the exterior of the coal feeder shell, and a dust suppression device is arranged outside the coal outlet pipe; the conveying device comprises a weighing type belt, a conveying belt and a scraping assembly which are sequentially arranged in the coal feeder shell from top to bottom; the blanking point adjusting device comprises an impact plate rotationally connected with the inner wall of the coal feeder shell and a buffer assembly arranged between the impact plate and the inner wall of the coal feeder shell; the dust suppression device comprises a lifting assembly arranged at the top end of the outer portion of the coal outlet pipe and a dry fog spraying assembly arranged at the bottom end of the outer portion of the coal outlet pipe. According to the dust overflow prevention system, the dust suppression effect can be adjusted according to the quantity of materials, and therefore the dust suppression purpose is achieved under the condition that material conveying is not affected.

Description

technical field [0001] The invention mainly relates to the technical field of a coal conveying system, in particular to a dust prevention system for a boiler coal feeder. Background technique [0002] The coal feeder is a mechanical device that can accurately adjust the coal feed to the coal mill according to the load requirements. It is arranged between the raw coal scuttle and the coal mill. In the direct-blowing pulverizing system, the amount of coal fed directly adapts to the load of the boiler. [0003] According to a silo ring-type impeller feeder equipment provided by the patent literature with the application number CN202011134974.0, it can be known that the feeder includes a material (coal) dust cover, an impeller material (coal) device, an impeller shell Body, main drive device, impeller removal mechanism, arc-shaped car body, travel drive device, differential travel mechanism, ring track support, floating drive device for coal feeding car, following dry fog dust ...
