Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0037] refer to figure 1 , is a coal slime cleaning utilization device disclosed in the present invention, including a flotation device 1 , a first dehydration device 2 , a buffer tank 3 , a sedimentation tank 5 , a second dehydration device 6 and a circulating water tank 7 . The flotation device 1 includes a pulp preparer 11 and a flotation machine 12. The pulp in the pulp preparer 11 first enters the flotation machine 12, and the flotation machine 12 is connected to the first dehydration device 2 and the buffer tank 3, and the flotation machine 12 floats The extracted flotation concentrate enters the first dehydration equipment 2, and the flotation concentrate outputs the clean coal product 8 and circulating water through the first dehydration equipment 2, and the circulating water enters the circulating water tank 7.

[0038] The remaining flotation taili...

Abstract

The invention relates to a coal slime cleaning and utilization device, which includes flotation equipment, a first dehydration equipment, a buffer tank, a sedimentation tank and a second dehydration equipment, and the flotation concentrate produced by the flotation equipment enters the first dehydration equipment for Clean coal products are obtained by dehydration, and the remaining flotation tailings from the flotation equipment enter the buffer tank, the buffer tank is connected to the sedimentation tank, and the sedimentation tank is connected to the second dehydration equipment. A sealing door capable of opening and closing the slag discharge port is connected at the center, and a collection mechanism is fixedly connected to the periphery of the buffer cylinder to receive the effluent from the slag discharge port and transport the effluent to the second dehydration equipment. The invention has the effects of convenient cleaning and recycling of sediment in the buffer cylinder.

Description

technical field [0001] The invention relates to a coal washing process, in particular to a coal slime cleaning and utilization device. Background technique [0002] Coal washing is an indispensable process of coal deep processing. The coal directly mined from the mine is called raw coal. Raw coal is mixed with many impurities during the mining process, and the quality of coal is also different. Coal with small internal ash and large internal ash is mixed in Together. Coal washing is an industrial process that removes impurities in raw coal, or classifies high-quality coal and low-quality coal. The existing coal washing process mainly separates clean coal, medium coal and gangue through a three-product dense medium cyclone, and then dehydrates and removes medium to form products. After that, the coal with smaller particle size can be screened by flotation process, and the tailings after flotation can get circulating water and coal slime through sedimentation. [0003] Befo...
