The invention relates to a separator for a coal mine, in particular relating to a separator integrated with cyclonic separation and cyclonic flotation. The separator comprises a feeding cylinder, a pre-separating cylinder, a coarse grain separation cyclone, a concentrate cyclone, a fine grain separation cyclone and a static flotation cylinder, wherein the upper part of the pre-separating cylinder is provided with a cyclonic flotation fine coal outlet, a quality-regulating outlet and a fine grain outlet; the lower part of the pre-separation cylinder is provided with a coarse grain outlet; the fine grain separation cyclone and a coarse separation cyclone are respectively provided with a cyclonic flotation fine coal discharge hole, a quality-regulating discharge hole, a connecting port and a discharge hole, and the connecting port is provided with the concentrate cyclone which is provided with an overflow gate and an underflow gate; the quality-regulating outlet, the quality-regulating discharge hole and the overflow gate are connected with a central cylinder; the cyclonic flotation fine coal outlet and the flotation fine coal discharge hole are communicated with a flotation concentrate tank; and a circulating outlet pipe is arranged between the lower part of the feeding cylinder and the static flotation cylinder. The invention has the advantages of wide range of feed particle size, high separation efficiency, small occupied area and energy conservation.
Description
Technical field: [0001] The invention relates to a separator for coal mines, in particular to a separator integrating swirl separation and swirl flotation. Background technique: [0002] There are following advantages and disadvantages in the known sorting equipment applicable to less than 1mm coal: [0003] [0004] It can be seen that none of the above known coal slime separation equipment can complete the effective separation of 0-1mm coal slime at one time. Invention content: [0005] The purpose of the present invention is to solve the disadvantages of the background technology and provide a sorting machine integrating cyclone sorting and cyclone flotation. [0006] The present invention adopts following technical scheme: [0007] A sorting machine integrating swirl separation and swirl flotation, including an air compressor, a feeding cylinder, a pre-selection cylinder, a coarse-grain separation cyclone, a concentration cyclone, and a fine-grain separation cyclo...
