Chain coal burning boiler with automatic ash discharging device

Abstract

The invention concretely provides a chain coal burning boiler with an automatic ash discharging device, which solves the problem that no automatic ash discharging devices are arranged for current chain coal burning boilers. The invention comprises a wind chamber, and the bottom part of the wind chamber is fixedly sealed with a casing pipe; ash discharging holes are arranged above and below the cylindrical surface of the casing pipe; the casing pipe is provided with a revolving shaft which passes through the side plate of the wind chamber; the revolving shaft is fixed with an ash discharging wheel which is composed of a wheel hub, a wheel plate and clapboards which are arranged at two ends of the wheel plate; a chain wheel is sheathed at one end of each revolving shaft outside the side plate of the wind chamber; the outer end surface of the chain wheel is occluded with a safety clutch which is fixed with the revolving shaft; a chain is sheathed between every two adjacent chain wheels; the chain wheel on one of the revolving shaft is connected with a speed reducer through a chain; and the speed reducer is connected with a motor. The invention not only greatly reduces labor intensity of workers, but also avoids the problem of air blast discharging when discharging ash, improves combustion quality of boilers and reduces pollution to the environment; the invention simultaneously has the advantages of low cost, simple installation and convenient maintenance.

Description

technical field [0001] The invention relates to a boiler, in particular to a chain-type coal-fired boiler, in particular to an efficient and safe chain-type coal-fired boiler with an automatic ash discharge device. Background technique [0002] The existing chain-type coal-fired boilers include coal-fired boilers with thin ash tubes and coal-fired boilers without thin ash tubes. The coal-fired boilers with thin ash tubes are made by passing the upper part of the thin ash tubes in the compartment of the furnace wall. , these two kinds of coal-fired boilers both include the upper grate and the lower grate driven by the driving wheel and the driven wheel. Between the upper and lower grate are fixed a number of air chambers placed in a matrix and located in the side plate of the air chamber. The traditional The ash discharge method is usually to make the bottom plate of the furnace exhaust chamber into a movable bottom plate that can be pushed and pulled by the ash release rod. ...
