The utility model discloses a movable wheel and bucket type tailing dehydrator comprising a rack, wherein the rack is provided with a sand settling case; a swirler is arranged at the top left of the sand settling case; a wheel and bucket type dehydrator is arranged at the top right of the sand settling case and comprises a central shaft; the central shaft is fixedly sheathed with a barrel-shaped dehydrator body; the annular outer wall of the dehydrator body is provided with a sand bailing hopper that is inclined clockwise, and the sand bailing hopper at the lower side of the barrel body of the dehydrator is in the sand settling case; the right side of the sand settling case is provided with a tailing unloading chute; the lower right of the rack is provided with a transport belt capable of driving in a circulatory manner; and the outlet of the tailing unloading chute is opposite to the input end of the transport belt. The movable wheel and bucket type tailing dehydrator solves the problem that a thickener and a tailing warehouse occupy a large amount of land, and can simultaneously achieve the function of piling up tailings dry stacks. Classified fine grains of sand can be used as raw materials of aerated concrete building blocks. Comprehensive utilization of tailings is realized and waste is turned into wealth. The movable wheel and bucket type tailing dehydrator is lower in investment by 50-70% than the regular concentrated filtration process, the energy consumption is reduced by 30-50%, and the operating cost is decreased by 30-50%.
