Fire coal device capable of removing coal ash

Abstract

The invention relates to a combustion furnace, in particular to a fire coal device capable of removing coal ash. The fire coal device can achieve the aim of effectively separating the coal ash from a coal stove hearth and comprises a coal stove with an internal combustion chamber, a coal outlet communicated with the internal combustion chamber of the coal stove is formed in the lower portion of the coal stove, and a screen plate is arranged on the coal outlet and provided with a plurality of fine holes. The fire coal device further comprises an impeller arranged above the screen plate and an impeller shaft arranged below the impeller, a driving device in transmission connection with the impeller shaft is arranged below the screen plate, blades are arranged on the impeller, and densely-distributed through holes are formed in the impeller. According to the fire coal device capable of removing the coal ash, the driving device drives the impeller to rotate through the impeller shaft; and through two times of ash discharging through the impeller and the screen plate, the coal ash is effectively discharged from the coal stove hearth, briquette burning is more sufficient, and the fire coal efficiency is greatly improved.

Description

technical field [0001] The invention relates to a combustion furnace, in particular to a coal burning device capable of removing coal ash. Background technique [0002] At present, when burning briquettes, a large amount of fine-grained coal ash will be brought into the furnace of the coal furnace. During the coal combustion process, the coal ash enters the coal furnace and burns immediately, which leads to the accelerated combustion of the briquettes entering the furnace. A large amount of heat cannot be effectively utilized, and the usage of briquettes is also increased, and a large amount of coal ash will be produced during the combustion process, and the coal ash will accumulate on the wall of the combustion chamber to form a block and be adsorbed on the wall of the combustion chamber, thereby Insufficient combustion of briquettes is caused, so it is necessary to separate coal ash from the coal furnace to improve coal combustion efficiency. Contents of the invention ...
