Full-automatic continuous coal distribution device

Abstract

The invention discloses a full-automatic continuous coal distribution device which comprises a driving belt wheel, a driven belt wheel, a belt, a speed reducer, a coal conveyor belt, a chain, a coal bunker, a coal discharging hopper, a driven chain wheel, a coal plough lifting platform, a coal plough, a coal plough trolley and a coal discharging channel. According to the device, an original fixedcoal plough is replaced with a movable coal plough, and an original fixed coal discharging port is modified into two parallel coal discharging channels in the same length as the total width of the coal bunker; furthermore, the coal plough can reciprocate to form relative movement to the coal conveyor belt, and finally it is ensured that coal on the coal conveyor belt is uniformly distributed in the coal bunker; and the problem of separation of coal briquettes from coal surfaces is solved. A motor is controlled through a PLC in the whole system to achieve lead screw lifting and reciprocating motion of the coal plough. The combustion efficiency of a boiler can be improved through the whole device, uniform mixing of fire coal is achieved, and the problem of insufficient coal combustion is solved; and the oxygen content of the boiler is reduced, so that the emission of nitric oxide and sulfide is reduced, and the purposes of energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to an automatic coal distribution device for coal transportation in coal mines, coal transportation in heating boilers, coal transportation in power plants, etc., specifically, a fully automatic continuous coal distribution device applied to boilers. Background technique [0002] With the development of my country's national economy, the boiler manufacturing industry has made great progress. The standards of the boiler industry are becoming more and more standardized, the technical level is gradually improving, the industrial scale is also significantly expanding, and the variety of products is also increasing. However, during the development of this industry, resource waste and environmental damage are also very serious. Compared with developed countries, my country's coal-fired boilers have low combustion efficiency and high energy consumption. Therefore, improving the combustion efficiency of coal-fired boilers is of great sig...
