Description

Modularized coal mine underground wind power coal dressing equipment Technical Field The utility model relates to the technical field of wind coal dressing equipment, in particular to modularized underground wind coal dressing equipment for a coal mine. Background Along with the continuous development of coal mining technology, the requirements on underground coal preparation equipment are increasingly improved, on one hand, the equipment is required to be capable of efficiently running in a limited space and is convenient to install, detach and move so as to adapt to the continuously-changed working environment and mining layout in the pit, on the other hand, the coal preparation process is required to have higher precision and efficiency, impurities such as gangue, tuberculosis sulfur and the like can be effectively removed, the utilization rate of coal resources is improved, the influence on the environment is reduced, and the energy consumption and the operation cost are reduced. According to incomplete statistics, the gangue content in raw coal just mined in the coal mine is about 15 percent on average, and the gangue content in top coal is about 20 percent. In the traditional operation of coal industry, coal mining and coal dressing are generally divided into two independent operation systems, raw coal is not processed underground by the coal mine, but is mixed together, directly transported and lifted to a ground coal bunker, and then a large amount of gangue is discharged by a coal dressing plant through washing and dressing. Thus creating a number of disadvantages: (1) A large amount of invalid transportation is brought, and the actual productivity of the coal mine is reduced. Gangue mixed into raw coal is transported underground, lifted to the ground and transported to a coal preparation plant for further treatment, and about 16% of electric energy and equipment loss are directly wasted due to ineffective transportation, such as tearing of a belt, impact on a belt bracket, abrasion of equipment such as a chute large chain of a scraper conveyor, a roller of a coal mining machine, a crusher and the like caused by the gangue. (2) Occupies a large amount of sites and damages the ecological environment. The waste rocks discharged from the ground coal preparation plant are required to occupy a large number of sites for stacking and storage, and sulfur content and combustible matters in the waste rocks are extremely easy to form spontaneous combustion, so that the damage of ecological environment is further aggravated, the storage of the waste rocks in the whole country is more than 60 hundred million tons at present, and the waste rocks of 6-8 hundred million tons are increased each year. (3) Waste of a large amount of gangue and accumulation of the gangue into mountains, and goaf causes collapse of the ground and damage of a fertile farmland. Therefore, development of underground coal preparation technology and equipment, construction of underground coal preparation technology and matched equipment systems thereof and development of utilization of resources of gangue in the pit can form a complete industrial chain, and is urgent to be researched, developed, popularized and applied in the coal industry in China.
