The present invention discloses a mud-water separation device including a main tank body, the main tank body is provided with a cavity, the upper part of the main tank
body cavity is provided with a plurality of filter water suction ends, the filter water suction end is provided with a grid bracket and filter cloth, the plurality of filter water suction ends are in parallel connection on a water suction
pipe, the water suction
pipe is provided with a water suction pump, the upper end of the main tank body is provided with a
helical surrounding coil, the outer end of the coil and a
slurry delivery tube are communicated, a down-feed pipeline which is connected with the inner end of the coil is fixedly arranged in the main tank body, the terminal end of the down-feed pipeline opens toward the cavity, a spiral
conveyor belt is fixedly arranged in the
slurry delivery tube, the lower end of the main tank body is provided with a mud
discharge outlet, the
slurry delivery tube and a slurry
mixing tank are in connection, and the slurry
mixing tank is provided with an automatic quantitative feeding device used for conveying additives. The mud-water separation device can achieve automatic and continuous mud-water separation of the slurry, the mud-water separation efficiency is higher, operation is more convenient, and minimal labor is required. The mud-water separation device adopts an automatic quantitative additive feeding structure, so that additive addition is more precise, and the operation is more convenient.
