On-line thickener full-section concentration analysis device

The invention provides an on-line concentrator full-section concentration analysis device which comprises a box body, a rotatable cable winding and unwinding wheel and a concentration sensor for detecting the concentration of ore pulp are arranged in the box body, and the concentration sensor is provided with a flexible cable. When the cable winding and unwinding wheel rotates forwards and backwards, the flexible cable is driven to further drive the concentration sensor to move up and down through a hole in a bottom plate of the box body, and the moving length and direction of the flexible cable can be measured through the length measuring wheel; the display control device is used for processing data measured by the concentration sensor and data measured by the length measuring wheel so as to obtain concentration and thickness data of each layer in the sedimentation process of the thickener and further obtain full-section concentration detection data; the problem that it is difficult to provide full-section c
