Coal mine screening equipment for coal mining

Technical Field

The utility model relates to a colliery screening installation field, more specifically say, relate to a colliery screening installation that coal mining adopted.

Background

Coal washing is an indispensable procedure of coal deep processing, coal directly mined from a mine is called raw coal, a plurality of impurities are mixed in the raw coal in the mining process, the coal quality is different, coal with small inherent ash content and coal with large inherent ash content are mixed together, the coal washing is an industrial process for removing the impurities in the raw coal or classifying high-quality coal and poor-quality coal, along with the development of coal washing technology, composite dry coal washing gradually derives nowadays, compared with the traditional wet coal washing, the dry coal washing has lower water resource requirement and is more environment-friendly, and the coal washing can be carried out in areas with deficient water resources and colder climates.

Most of the existing dry coal washing technologies are to use wind power for screening, raw coal is pre-crushed after being mined out to enable the raw coal to be in a granular shape with similar size, then the raw coal is added into a feeding port and falls into an inclined separation bed through the feeding port, a bottom plate of a suspension bed is hollow, a vibrator is connected to the side edge of the separation bed, an air chamber is connected to the lower end of the separation bed and is connected with an air inlet pipe, an air blower blows air into the air chamber through the air inlet pipe, fillers with different granularities and densities are filled in the air chamber, therefore, the wind power blowing to the separation bed after entering the air chamber is different in size, the raw coal falls onto the separation bed through the feeding port during the coal washing operation, the raw coal can roll on the separation bed under the action of self weight and the vibrator, and the strong wind blowing to the separation bed during the rolling process of the raw coal in the air chamber can wash the raw coal, raw coal is divided into clean coal, middlings and gangue.

The original coal washing work is usually carried out on the well, however, in the actual production process, mine workers find that a large amount of low-quality coal mine waste materials and waste rocks are generated after raw coal is washed, and in order to prevent accidents such as caving or collapsing of an ore machine, the low-quality coal mine and the waste rocks are sent back to the mine to fill the mine, so that a large amount of energy is wasted in the coal mining process, the production efficiency of coal mining is reduced, therefore, the mine workers further put the coal washing work underground, factors such as underground environment inevitably cause that a wet coal separation technology is difficult to normally carry out, and technicians design a composite dry coal separator with a compact structure, thereby facilitating the coal separation work of the mine workers underground, and the coal separation work often needs to follow the progress of coal mining and cannot be fixed at a certain point, the underground pavement environment is complex, and the existing composite dry coal separator is difficult to freely move underground.
