The utility model provides a lotion thickener underflow circulation homogenization device belongs to the tailing lotion and deals with and the mineral engineering field. The device includes underflow pump, nucleon concentration meter, flowmeter, four valves, homogenizer and underflow circulation pipeline. The well that gathers materials under underflow pump one end and the lotion concentrator links to each other, and the other end links to each other with the nucleon concentration meter, and nucleon concentration meter and flowmeter, valve no. 1, homogenizer are established ties in proper order, and valve no. 2 lies in flowmeter and valve between one, valve no. 3, four parallel connection on the valve. The homogenizer comprises flange, pipeline, stirring vane. Through real -time underflow concentration value, the underflow flow value that obtains of nucleon concentration meter, flowmeter, adjust the rotational speed of underflow pump, the switch of selector valve no. 3, valve no. 4. The utility model provides a lotion thickener underflow homogenization circulating device simple structure, the homogenization that can effectively realize the lotion thickener underflow, controllableization circulation avoid the lotion concentrator to press the emergence of harrow, shut down accident.
