Coal loosening device

Abstract

The invention provides a device, which is mounted on a grate below a boiler coal bucket, and used for loosening raw coal by the aid of movement power of the chain grate and the raw coal. The scheme of the device mainly includes that the length of the device is controlled to be smaller than the width of the whole grate by the size of a grate bar by hot-rolled inequilateral angle iron (1). Two right-angle sides of the hot-rolled inequilateral angle iron are sealed by a steel plate (2) with a moderate width, two ends of the hot-rolled inequilateral angle iron are also sealed by steel plates (3) and (4), a stereoscopic triangle is formed, a long side of the stereoscopic triangle is downwardly placed on the grate, two pipes (5) and (6) of the same length are parallelly welded on the surface of the triangle with the long right-angle sides, one end of each pipe is provided with a screw socket, other pipelines (7) and (8) are connected onto a left side wallboard and a right side wallboard in front of the grate respectively through screw sockets, cooling water is led into the pipelines, and wear-resistant sections are welded below a bottom plate of the coal loosening device at intervals through flat iron (9), so that wear of the coal loosening device due to the grate is relieved.

Description

technical field [0001] The invention relates to a boiler equipment, which is installed on the fire grate under the coal hopper of the boiler, and relies on the coal seam to move on the fire grate chain to loosen the coal seam, so that the raw coal can enter the furnace for more complete and thorough combustion. technical background [0002] At present, most chain boilers are not equipped with a coal loosening device in operation. The raw coal must pass through the coal gate before entering the furnace from the coal hopper. The role of the coal gate is to fix the thickness of the coal seam and control the amount of coal input. When the raw coal meets the coal gate, the raw coal is compressed by the opposite force of the coal gate. Therefore, the raw coal entering the furnace has poor ventilation and poor combustion, and black slag is easy to appear, resulting in waste of raw coal. Moreover, the combustion is not good, and the temperature is not high, which affects production....

AI Technical Summary

Problems solved by technology

When the raw coal meets the coal gate, it is compressed by the force of the opposite direction of the coal gate. Therefore, the raw coal entering the furnace has poor ventilation and poor combustion, and black slag is easy to appear, resulting in waste of raw coal.

Moreover, the combustion is not good, and the temperature is not high, which will affect the production
