Boiler slag discharging device

Abstract

The invention belongs to the technical field of boiler auxiliary devices, and particularly relates to a boiler slag discharging device. The device comprises a machine body assembly, a pulverizing assembly and a conveying assembly. The machine body assembly comprises a rack, a conveying channel, a guiding channel, a pulverizing chamber and a material receiving hopper. The rack is fixed to the ground, and the conveying channel is located above the rack. A transmission belt is used for driving pulverizing rollers to rotate, a better pulverizing effect can be achieved through the three cone spiralpulverizing rollers, and generation of large slag blocks is reduced. The two ends of the pulverizing rollers are rotationally connected with the pulverizing chamber, every two pulverizing rollers arein transmission connection through an auxiliary transmission belt, it can be guaranteed that the pulverizing rollers have power input, and the phenomenon of belt jamming is avoided. The guiding and pulverizing functions can be conducted on crushed slag, accordingly, a better pulverizing effect is achieved, every two adjacent pulverizing rollers are placed in a staggered manner, and a better crushed slag pulverizing effect is achieved through a reasonable structure.

Description

technical field [0001] The invention belongs to the technical field of boiler auxiliary devices, and in particular relates to a boiler slag discharge device. Background technique [0002] The main working principle of the boiler is a kind of thermal equipment that uses the heat energy released after fuel combustion or the waste heat in industrial production to transfer to the water in the container to make the water reach the required temperature or steam at a certain pressure. The two parts of the "furnace" are carried out at the same time. After the water enters the boiler, the heat absorbed by the heating surface of the boiler in the steam-water system will be transferred to the water, so that the water will be heated into hot water with a certain temperature and pressure or steam will be drawn out for application. In the combustion equipment part, Fuel combustion continuously releases heat, and the high-temperature flue gas generated by combustion transfers heat to the h...

Problems solved by technology

[0003] Existing boilers use the heat energy generated by the combustion of solid combustion materials to heat water to increase the temperature of the water and convert energy. However, after the combustion of solid combustion materials such as coal, large residues may remain due to insufficient combustion. When the slag discharge device is conveying waste slag, large pieces of residue will be stuck between the conveyor belt and the pipe wall, resulting in unsmooth transmission
