Operation principle:
Black water from kaskad apparatus for pre-flotation pulp conditioning gets into feed inlet barrel 1; Circulating pump is injected preparatory separation tube 2 with black water; Black water is also done axially-movable when in preparatory separation tube 2, making circular motion; Near the downward axially-movable of the work of inwall, the axially-movable that makes progress near the work at center, and be formed with the water column that air column exists; In preparatory separation tube 2 upper inside wall the plenum chamber made from micropore ceramics 15 is housed; Compressed air got into plenum chamber 15 and saw through micropore ceramics and arrives preparatory separation tube 2 inwalls formation microbubble this moment; Microbubble is under the effect of descent waterflow; Inwardly motion downwards, microbubble are caught thin cleaned coal at the volley and are arrived air column with the current discharge that moves upward; Coarse-grained material in the black water and high density fine gather preparatory separation tube 2 bottoms under centrifugal action, and export 16 discharges by the coarse grain of bottom and feed the cobbing cyclone 7 that concentrates cyclone 4 is housed; Fine in the black water exports 17 discharges by the particulate on preparatory separation tube 2 tops and feeds the fine particle separation cyclone 3 that concentrates cyclone 4 is housed.
Be provided with cyclone flotation cleaned coal outlet 5, quality of regulation outlet 6 on the top of preparatory separation tube 2, cyclone flotation cleaned coal outlet 5 its water outlets get into flotation concentrate ponds 27; In the quality of regulation outlet 6 control valve 18 is housed, its water outlet gets into the central tube 8 of static flotation tube 10, adjusts the aperture of control valve 18, can control the quality of cyclone flotation cleaned coal.
Get into the material fine particle separation cyclone 3 and the cobbing cyclone 7 respectively from outlet 17 of the particulate of preparatory separation tube 2 and coarse grain outlet 16; Under action of centrifugal force, accomplish sorting by density, the bottom discharge mouth 21 of fine particle separation cyclone 3 and cobbing cyclone 7 is all discharged heavy product; Light product 24 is discharged to feed and is concentrated cyclone 4 from the connectivity port, and what discharge from the underflow opening 22 that concentrates cyclone 4 is head coal product; Discharge the central tube 8 that material gets into static flotation bucket 10 from the overfall 25 that concentrates cyclone 4.
The plenum chamber made from micropore ceramics 15 is housed respectively on fine particle separation cyclone 3 and cobbing cyclone 7 barrels; When getting into plenum chamber 15 and see through micropore ceramics arrival fine particle separation cyclone 3, compressed air forms microbubble with cobbing cyclone 7 inwalls; Microbubble is under the effect of descent waterflow; Inwardly motion downwards, microbubble are caught thin cleaned coal at the volley and are arrived air column with the current discharge that moves upward, and are provided with cyclone flotation cleaned coal outlet 5, quality of regulation outlet 6 on fine particle separation cyclone 3 and cobbing cyclone 7 tops; In the quality of regulation outlet 6 control valve 18 is housed, its water outlet gets into the central tube 8 of static flotation tube 10; The pan feeding of static flotation tube 10 is fed by central tube 8; Central tube 8 is connected with cone-shaped diffuser 11 and dentation discharging opening 9 is arranged; Because of being entrained with bubble in the pan feeding, the material that from dentation discharging opening 9, comes out carries out a flotation, rest materials with descending water along cone-shaped diffuser 11 to barrel; Compressed air gets into plenum chamber 15 and sees through micropore ceramics and forms microbubble; Microbubble can float thing and bring to liquid level; Do not have the floating material of going up to drop down onto the back taper bottom that is connected with cone-shaped diffuser 11 belows, material is by density stratification in the back taper bottom, and the awl end is that heavy product is expelled to cyclone flotation mine tailing 30 by mine tailing blow-off valve 12; Awl top is light product, is extracted out by circulating pump through cyclic water outlet pipeline 27 and participates in choosing again.The liquid level height of static flotation tube 10 can be controlled by bottom discharge valve.
