Coal gangue grading recycling device

Abstract

The invention discloses a coal gangue grading recycling device, and relates to the technical field of coal screening equipment. A fixed plate is perpendicularly and fixedly arranged on the right sideof the inner top of a box, a gap is arranged between the fixed plate and the right side wall of the box, a sliding rail is fixedly arranged on the inner top of the box, a sliding block is slidably arranged on the sliding rail, a connecting column is perpendicularly and fixedly arranged at the bottom of the sliding block, a screening mechanism is fixedly arranged at the bottom of the connecting column, a screw rod is fixedly arranged at the output end of a first motor and rotatably arranged in the middle of the connecting column through a thread in a penetrating mode, first and second discharging openings are sequentially formed in the left side wall of the box from top to bottom, a chute is fixedly arranged on the inner side wall of the box at the bottom of the second discharging opening,and the right side of the chute is arranged under the screening mechanism. According to the coal gangue grading recycling device, multi-grade screening can be conducted on crushed coal gangue, the utilization efficiency of the coal gangue can be improved, the pollution of an operating environment is prevented, the physical and mental injury to a worker is reduced, and meanwhile, the waste of materials can be reduced.

Description

technical field [0001] The invention relates to the technical field of coal screening equipment, in particular to a coal gangue classification recycling device. Background technique [0002] Coal gangue is solid waste discharged during the coal mining process and coal washing process. It is a black-gray rock with low carbon content and harder than coal that is associated with coal seams during the coal formation process. [0003] The overflow or leaching of sulfide in coal gangue will pollute the atmosphere, farmland and water bodies. Coal gangue will also spontaneously ignite and cause fires, or collapse in the rainy season, silting up rivers and causing disasters; the development and utilization of coal gangue has become a new industry now, such as the use of coal gangue Gangue is used to make environmental protection bricks, etc. Before the production, the gangue needs to be crushed and then used. After crushing, it needs to be screened. A large amount of coal gangue powd...

Problems solved by technology

[0003] The overflow or leaching of sulfide in coal gangue will pollute the atmosphere, farmland and water bodies. Coal gangue will also spontaneously ignite and cause fires, or collapse in the rainy season, silting up rivers and causing disasters; the development and utilization of coal gangue has become a new industry now, such as the use of coal gangue Gangue is used to make environmental protection bricks, etc. Before the production, the gangue needs to be crushed and then used. After crushing, it needs to be screened. A large amount of coal gangue powder will be produced during open-air screening, which will pollute the operating environment and cause material damage. waste, so there is an urgent need for coal gangue graded recovery and utilization devices
