Description

A kind of coal slime flotation machine
Technical field
The utility model relates to a kind of coal slime flotation machine.
Background technology
Existing coal slime flotation machine impeller adopts six double-deck umbellate forms mostly, and levels blade evenly aligns and do not misplace, cause beat number of times few, reverse, shear turbulence number of times is few, and causes liquid level magic flower, the shortcomings such as remineralization efficacy is poor, and separating effect is poor.
Summary of the invention
In order to overcome above defect, the purpose of this utility model is to provide a kind of coal slime flotation machine.
The technical solution of the utility model is:
A kind of coal slime flotation machine, it is characterized in that: by cell body, rabbling mechanism, transmission mechanism, foam scraping machine, level adjusting mechanism, maintenance ore drawing mechanism, walk on stage and brace summer composition, described foam scraping machine and level adjusting mechanism, maintenance ore drawing mechanism, walk on stage and be fixed on cell body with brace summer, described cell body inside is provided with the false end, the false end, is provided with current stabilization arc, middle upper portion of the false end has installed the bottom of rabbling mechanism, rabbling mechanism top is connected and fixed on brace summer, rabbling mechanism is connected by the belt of transmission mechanism, the charging aperture of cell body and discharge outlet are located at cell body two ends respectively.
The utility model coal slime flotation machine, it is characterized in that: described rabbling mechanism is made up of belt pulley, bearing housing, casing rack, stator cover plate, impeller, locking nut, mozzle, upper adjustable ring, lower adjustable ring and air inlet pipe, belt pulley is fixedly connected with bearing housing by axle, bearing housing bottom is fixed with casing rack, described casing rack inside is fixed with rotating shaft, adjustable ring is provided with between mozzle and stator cover plate, impeller locking nut is fixed on axle, and stator cover plate is connected with casing rack by ring flange.
The utility model is double-deck umbrella shape, and upper and lower two-layer design respectively has 6 blades and full communication between the higher and lower levels, and levels blade evenly misplaces, and upper strata blade is in the centre of the die cavity that adjacent two blades of lower floor are formed; Cause many beats, many torsions, many shear turbulences, improve remineralization efficacy, thus improve separating effect.
Operation principle of the present utility model is: the feed box of ore pulp through being located at flotation device pan feeding end enters under the vacation of bottom in cell body, the fresh ore pulp of major part and component loops ore pulp enter impeller bottom through rabbling mechanism, another part ore pulp enters the top of rabbling mechanism stator cover plate from false bottom perimeter, negative pressure is produced under the effect of turbine centrifugal power, the coal grain of mineral laden bubble and fresh mineralising is formed under extrusion shearing and turbulent shear effect, the coal grain of hydrophobicity mineralising and the bubble hit of mineralising, adhesion between stator blade wheel blade; Mineral laden bubble rises to froth bed with coal grain, is discharged by scraper plate, and chats then enters next flotation cell through chats case, so goes round and begins again, until discharge true tailings at last flotation cell through tailings flashboard, completes floatation process.
The beneficial effects of the utility model are: the utility model is because impeller blade levels blade evenly misplaces, and upper strata blade is in the centre of the die cavity that adjacent two blades of lower floor are formed; Cause repeatedly beat, repeatedly torsion, repeatedly turbulent shear, to coal grain mineralising more, mineral laden bubble more, more hydrophobicity mineral-rich coal grains and mineral laden bubble are come in contact, and the midge ability of impeller and gettering ability high, there is higher flotation speed, thus improve remineralization efficacy, thus improve separating effect.Also the flotation compared with coarse grain and difficult float coal is suitable for.
Accompanying drawing explanation
Fig. 1 is a kind of coal slime flotation machine of the utility model rabbling mechanism structural representation.
Detailed description of the invention
