Description

Technical Field

[0001] The utility model belongs to the technical field of coal engineering, and specifically relates to a coal cleaning device for coal engineering. Background Technique

[0002] At present, in the processes of coal mining and processing, coal washing is an essential link in coal processing. Dust and waste rocks are removed by water flow, and the ash content and sulfur content are reduced. Through coal washing, not only can the environmental protection purpose be achieved, but also the utilization rate of coal can be improved. The reason for using water for cleaning is that the coal just mined from the ground is called raw coal, which has many impurities, is relatively dry in texture, and is prone to dust generation. After being washed with water, the raw coal is relatively moist, which can effectively reduce the potential safety hazards brought during the storage, transportation, and use of coal, and at the same time reduce environmental pollution and transportation costs.

[0033] Specifically, the conveyor mesh belt 2 includes a driving roller 201. At a position corresponding to one side of the driving roller 201, there is a driven roller 202. A conveyor mesh belt 203 is connected between the driven roller 202 and the driving roller 201. The dirt collection box 9 is located inside the conveyor mesh belt 203.

[0034] Further, a water injection port 13 is provided at the top of the water storage tank 4, and a liquid level window is provided on one side of the water storage tank 4.

[0035] Furthermore, the coal turning component 12 includes a rotating rod 121, the rotating rod 121 is fixedly connected with a coal turning frame 122, the position of the coal turning frame 122 corresponds to that of the conveying mesh belt 203, and the conveyed coal is turned to improve the cleaning effect.

[0040] Working principle and process: Start the drive motor 17. Then, the secondary sprocket 16 drives the tertiary sprocket 19 to rotate through the secondary chain 18. Subsequently, the driving roller 201, the driven roller 202, and the conveyor mesh belt 203 rotate, causing the conveyor mesh belt 2 to operate. At the same time, the secondary sprocket 16 drives the primary sprocket 14 to rotate through the rotating rod, and drives another primary sprocket 14 to rotate under the action of the primary chain 15, thereby driving the rotating rod 121 of the material turning assembly 12 to rotate, causing the material turning frame 122 to rotate. Place the coal on the conveyor mesh belt 2. As the conveyor mesh belt 2 operates, the coal is transported to the gantry 3 position. Start the primary water pump 5.

During the moving and flushing process of the coal, the material turning frame 122 will turn the coal to improve the cleaning effect of the coal. The sewage generated by the cleaning will pass through the conveyor mesh belt 203 and fall into the sewage collection box 9. Subsequently, the sewage passes through the sewage discharge pipe 10 and is discharged from the sewage discharge port 114 of the filtration and recycling assembly 11, falling onto the herringbone filter plate 112 in the treatment tank 111. The impurities in the sewage are filtered on the herringbone filter plate 112. Under the impact of the water flow, the impurities will be washed onto the sewage collection mesh plate 113 to reduce the possibility of blockage of the herringbone filter plate 112. Start the secondary water pump 115. The filtered water in the treatment tank 111 is re-introduced into the water storage tank 4 through the water supply pipe 116 to form a recycling loop.
