Summary of the invention
For overcoming prior art defect, the object of the present invention is just to provide a kind of bauxite forward flotation refuse filter press material loading combination unit, effectively can solve mine tailing underflow and enter the problem that the refuse filter press material loading time is long, the filter cake feed pump flow passage part life-span that is thinner, refuse filter press is short.
The technical scheme that the present invention solves is, comprise the feeding pump scanning wake flow, the subsider of mine tailing, the feed pump of refuse filter press and refuse filter press, the feeding pump discharging opening scanning wake flow is communicated with the charging aperture of cyclone, the subsider import of the overflow outlet mine tailing of cyclone, the upper oral part of the underflow outlet cone tank of cyclone, the outlet of cone tank is connected with line pump, line pump is communicated with the subsider underflow pipe of mine tailing, the feed pump import of refuse filter press is connected in the subsider underflow pipe outlet of mine tailing, the outlet refuse filter press of the feed pump of refuse filter press.
Structure of the present invention is simple, easy to install, effective, efficiently solves mine tailing underflow and enters the problem that the refuse filter press material loading time is long, become the feed pump flow passage part life-span of cake weak effect, refuse filter press short, substantially increase refuse filter press operating efficiency.
