Description

Technical Field

[0001] The utility model relates to the technical field of coal mill equipment, and more specifically to a slag discharge structure of a coal mill. Background Technique

[0002] Coal is a mineral energy source that is widely used at present. Most of the original materials mined are large-sized blocks, which are not convenient for transportation and processing. Therefore, before being transported out of the mine, they have to be ground and crushed into fine particles by a coal mill to facilitate subsequent workers to transport and finely process the coal.

[0003] After retrieval, the existing patent (publication number: CN217341747U) discloses a slag discharge structure of a coal mill. When in use, the slag discharge plates distributed in a funnel shape at the top of the slag discharge frame are used to control the slag discharge speed. Through the mutual cooperation of components such as a reciprocating driving component and an intercepting plate, the intercepting plate can intercept and accumulate the slag material and discharge it in a timely and quantitative manner. This process is repeated, and all components are arranged outside the slag discharge frame to avoid the presence of horizontal bar components inside it, which may affect the smoothness of slag discharge. Moreover, since the slag material can be automatically discharged quantitatively, the problem of excessive material accumulation can be avoided. However, the inventor found the following problems in the process of implementing the present utility model: The above-mentioned slag discharge structure can control the slag discharge speed. When applied, it can only be applied to the surface of the conveyor belt. When it is necessary to discharge the coal slag onto the ground for stacking, the coal slag can only be discharged onto the inner bottom side of the slag discharge frame for accumulation, and it is impossible to evenly spread the coal slag on the ground as required. The placement range of the coal slag is narrow, which affects the normal use of the coal mill.

[0004] In view of this, the present utility model proposes a slag discharge structure of a coal mill to solve this problem. Utility Model Content
