Large thickener and installation method thereof
The invention provides a large thickener and an installation method thereof. The thickener comprises a tank body and a stirring device, wherein a central column hole is formed in the middle of the bottom of the tank body, and the stirring device comprises a central column, a stirring rake mounted on the central column and a driving device for driving the stirring rake to rotate; a central column of the stirring device is arranged in the tank body, and the lower end of the central column penetrates through a central column hole in the bottom of the tank body and is fixed on a central column base below the tank body; an underflow cone is connected between the tank body and the central column, the underflow cone is formed by splicing a forward taper pipe and an inverted taper pipe, and a small-diameter pipe orifice at the upper end of the forward taper pipe is connected with the column surface of the central column; and a large-diameter pipe orifice at the upper end of the inverted taper pipe is connected with the steel surface on the hole surface of the central column hole, a small-diameter pipe orifice at the lower end of the inverted taper pipe is connected with a large-diameter pipe orifice at the lower end of the forward taper pipe, and a plurality of sand outlet holes are formed in a seam between the inverted taper pipe and the forward taper pipe. According to the invention, an underflow cone can prevent mortar deposited on the stirring rake from blocking the sand outlet holes, and the problem of slurry leakage between the tank body and the center column can be solved.
本发明提供了一种大型浓密机及其安装方法。浓密机包括罐体和搅拌装置，在罐底的中部开有中心柱孔，搅拌装置包括中心柱、安装在中心柱上的搅拌耙以及驱动搅拌耙旋转的驱动装置；搅拌装置的中心柱设置在罐体内，其下端穿过罐底的中心柱孔固定在位于罐体下方的中心柱基上，罐体与中心柱之间接有底流锥，底流锥由正向锥管和倒向锥管拼合而成，正向锥管的上端小径管口与中心柱的柱面连接，倒向锥管的上端大径管口与中心柱孔的孔面上的钢质面相接，倒向锥管的下端小径管口与正向锥管的下端大径管口相接，并在二者的接缝处设有若干出砂孔。本发明设置的底流锥可以防止搅拌耙上淤积的砂浆堵塞出砂孔，还能解决罐体与中心柱之间容易出现漏浆的问题。
