Deslagging device of fan coal mill

Abstract

The invention discloses a deslagging device of a fan coal mill, and belongs to the technical field of machinery. The deslagging device comprises a deslagging pipeline, a deslagging pneumatic door, a material box, a weighing device and a transfer device; the deslagging pipeline is arranged below an iron accumulation groove of a shell, the deslagging pneumatic door is connected to the deslagging pipeline, the material box is connected to the lower part of the deslagging pipeline, and the weighing device is arranged on the material box; when the weighing device gives out a full box alarm, the deslagging pneumatic door is controlled to act, the material box is conveyed to a dumping place through the transfer device, and dumping of materials is completed. Compared with an original deslagging mode that slag is stacked in an iron accumulation groove, the deslagging device device of the fan coal mill achieves the function of discharging slag such as iron blocks and coal gangue which cannot be ground in the coal mill out of the machine shell in time, and secondary abrasion of the slag, which cannot be ground, to a beating wheel and a lining plate is avoided; and in addition, the deslagging device of the fan coal mill can easily transfer materials through the transfer device, and the problem that an iron accumulation groove of an original fan coal mill is difficult to clean is solved.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a slag discharge device for a fan coal mill. Background technique [0002] The material composition of coal is very complex, which is often mixed with non-grindable ore or scrap iron, as well as hard-to-grind coal gangue and other substances. Their existence will undoubtedly increase the wear on the internal components of the fan coal mill. [0003] The existing fan coal mill is not equipped with a slag discharge device, and the ungrindable slag is accumulated in the iron accumulation tank at the bottom of the casing under the action of gravity, and can only be cleaned when the coal mill is shut down for maintenance. And owing to be provided with striking wheel in the casing, the space is narrow and narrow, and this has increased the difficulty and the workload of clearing the accumulation iron groove greatly. At the same time, because the ungrindable slag cannot be discharged...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a fan coal mill slag discharge device, which can solve the problem that the existing fan coal mill can not discharge the slag that cannot be ground in time, and the slag with low quality will be blown up again in the casing. , re-deposition, and repeated cycles, which also greatly increase the wear and tear of the striking wheel and other components
