Abstract
A pre-flotation high efficiency slurry conditioning device for wide-particle-grade flotation, suitable for coal slime flotation. Said device comprises a slurry conditioning drum () having a columnar structure on top and an inverted frustrum structure below, an ore slurry outlet () is provided at an upper part of a side wall, ore slurry pump separation openings () are provided at two sides below the ore slurry outlet (), ore slurry jet openings () are respectively provided at two sides of the columnar structure, and circular cutting isolation plates () and flow guide plates () are provided in alternation at inner sides of the upper half of the slurry conditioning drum (); a dual channel jet circulation chemical feed system comprises chemical feed pipes (), each chemical feed pipe () comprises an inlet end, a diffusion end, and a chemical feed pipe opening arranged at a throat area of said pipe, the inlet end is connected to a three-way pipe by means of a centrifugal pump (), which is connected to an ore slurry inlet () and an ore slurry pump separation opening (), a mixing shaft () is provided in the axial direction within the slurry conditioning drum (), a plurality of mixing impellers () are arranged on the mixing shaft (), and the bottom-most two mixing impellers () and the lowest two circular cutting isolation plates () are arranged at a same horizontal height. The present apparatus can effectively improve coal slime hydrophobic flocculation and fine slime separation, improve an ore slurry preprocessing effect, and effectively alleviate internal flow field pressure within a flotation device.
