Description

Ring type mechanical stirring flotation machine

The utility model relates to the circular ring type mechanical agitation flotation device that swims and separate of coloured, black, mineral such as rare and nonmetal.

What flotation device utilization at present was maximum is mechanical agitation type and two kinds of inflation mechanical agitation types.The former ［ sees that＜clear and 60 year conference in the autumn branch researchs lecture collection " flotation device " of 100 anniversaries are founded in Japanese mining industry meeting so that the application of Wemco type machine is more, clear and in October, 60〉］, domestic widespread usage XJK type agitation impeller flotator (seeing " benficiation machinery " first phase in 1977).Genus inflatable mechanical agitation flotation device, (see U.S.Pats.4075089, Feb.21,1978 as the flotation device of truncate parabola, truncate conical agitator arm; 4283357 Aug.11,1981).All there be coarse granule, the big problem than heavy mineral ability of sorting in above-mentioned all kinds of flotation device.

The purpose of this utility model is: change the key part structure that directly influences ore pulp inflation and stirring extent and the flotation device that a kind of circular ring type agitator arm is provided, strong mixing makes coarse granule, fully suspends than heavy mineral greatly, and high dispersive is improved the sorting mineral ability.

For achieving the above object, the technical scheme of taking is:＜1〉forms the circular ring type agitator arm with blade and two truncated cone rings of some approximate circle curves.Its action principle is when agitator arm rotates, with vane curvature radius maximum point is the line of demarcation, upper impeller can be air-breathing, bead wires speed is that from bottom to top gradient from large to small distributes from the line of demarcation, the pressure that the bubble that spreads in the liquid phase is born under turbulent condition is also from bottom to top corresponding to be weakened, and then forms the stabilise bubbles group in ore pulp.Ore pulp can be aspirated in the impeller bottom, and ore pulp forms bicirculating flow of slurry up and down by the guiding of two truncated cone rings;＜2〉two jiaos of cell body rear walls, triangle current stabilization body is installed at cover plate oblique upper place, and its effect is the choked flow that is produced during by the current stabilization body by ore pulp and refluxes and be used for impelling the liquid level foam to move to downflow weir, in order to the eliminating concentrate;＜3〉the blade inner edge of guide plate and stirring wheel blade are concentric circles, to reduce the loss of stirring wheel rotational energy.

Accompanying drawing is a structural representation of the present utility model.

The drawing explanation: structure of the present utility model mainly comprises (one) rabbling mechanism; (2) cell body part; (3) transmission mechanism.Be described below respectively:

(1) rabbling mechanism by the vertical pivot (1) of tape spool bearing, cylindrical central sleeve (2), cover plate (3), guide plate (4), connect beam barrel (5), form like parts such as circular curve blade (6), frustum of a cone ring (7), (8).The ring flange at the bottom of vertical pivot (1) the upper shaft bearing and the upper end of cylindrical central sleeve (2) join, the lower end of cylindrical central sleeve (2) connects with cover plate (3) by bolt, cover plate (3) and guide plate blade (4) cast solid, guide plate blade (4) is a concentric circles with stirring wheel blade (6), vertical pivot (1) is terminal to be connected with beam barrel (5) with screw thread, the straight line of a plurality of blades (6) inserts in the groove of beam barrel (5) and with bolting symmetrically, two frustum of a cone rings (7), (8) use bolt and a plurality of blade (6) to fix and composition circular ring type agitator arm respectively.

(2) cell body partly is made up of cell body (9), triangle current stabilization body (10), stabilier (11), groove beam parts such as (17).

Cell body (9) is the ore pulp container that is welded with steel plate, the groove beam (17) of the useful bolting of upper port of cell body (9), rabbling mechanism is installed in the center of cell body (9) by groove beam (17), a leg-of-mutton current stabilization body (10) is fixed at two jiaos of places of cell body (9) rear wall respectively, current stabilization body (10) is fixed two rectangular steel plates for the both sides of the empty frame of triangle, and the another side is the space.The antetheca of cell body (9) is equipped with (11) two of rectangle stabiliers, and cell body (9) two side has stock inlet (14) and plasma discharge mouth (15) (schematic diagram is cutd open), and complete machine is fixed with anchoring bolt (16) and ground.

(3) transmission mechanism comprises that partly driving vertical pivot (1) rotates and scrape bubble plate transmission mechanism, and is identical with public flotation device.

The number in the figure name is called:

The 1-vertical pivot, 2-cylindrical central sleeve, 3-cover plate, the 4-guide plate, 5-beam barrel, 6-blade, 7,8-frustum of a cone ring, 9-cell body, 10-current stabilization body, the 11-stabilier, 12-overfall mouth, 13-air inlet, the 14-stock inlet, 15-plasma discharge mouth (cuing open among the figure), 16-anchoring bolt, 17-groove beam.

Use step of the present utility model is: work as electric motor starting, belt drives vertical pivot (1) and rotates, vertical pivot (1) makes agitator arm (blade and conical ring are formed) do to rotate synchronously by beam barrel (5), ore pulp is given to the center of cover plate (3) from stock inlet (14), because the centrifugal force that the impeller rotation produces is dished out ore pulp, impeller and cover plate form certain negative pressure between (3), extraneous air just automatically sucks through air inlet (13), air and ore pulp are at blade (6) and frustum of a cone ring (7) under the effect of impeller strong agitation, (8) fully mixing the blade that is directed to plate (4) in the cavity of being formed disperses, be on the tiny mineralized froth by the mineral of medicament effect and float on the upper port liquid level of cell body (9), be called scraper plate that the concentrate foam is rotated and scrape to collect to enter down and go on foot operation; The ore particle that can not form mineralising bubble in the ore pulp then sinks to cell body (9) bottom, gets rid of from plasma discharge mouth (15) as mine tailing, in the ore pulp as belong to the insufficient buoyancy of mineralising and be inhaled into impeller district ringing with flow of slurry again less than the ore particle of gravity.

The utility model has the advantages that: for metal and nonmetal deposits thing floatation separation process, mixing power is strong, the bubble spread high and size evenly, to pounce on dosings such as receiving agent few, is particularly suitable for the mineral floatation technique of coarse granule, big proportion. Laboratory test to certain iron ore, iron rough concentrate reverse flotation obtains iron content 67.32%, the rate of recovery is 78.57% iron ore concentrate, sorting the result with the conventional mechanical agitation type flotation machine compares, the iron grade improves 1.74%, and its yield improves 2.56%, now will drop into the technology examination, this cover plate and guide plate and rotor blade gap be greater than the 10-15 millimeter, working stability, easy to maintenance, few for existing investment for trnasforming urban land with flotation device, instant effect, is easy to promote the use.
