Embodiment
To describe technology contents of the present utility model, construction feature, the objects and the effects in detail, below in conjunction with implementation
Mode simultaneously coordinates accompanying drawing to be explained in detail.
Please with reference to Fig. 1, Fig. 2 and Fig. 3, understand as shown in the figure, a kind of preferred embodiment of the utility model is made for one kind
Paper scalping sand removing tank：Including cylinder 100, cone cylinder 200 and sand collecting chamber 300；The cone cylinder is arranged on bottom of cylinder, the sand collecting chamber
Top is connected by the first residual cake valve 301 with cone cylinder bottom, and the sand collecting chamber bottom is connected with the second residual cake valve 302；The cylinder
Side wall upper part is provided with stock inlet 101, and the barrel top is provided with grout outlet 103, and the grout outlet is provided with slurry-supplying valve 104；It is described
