A mineral separation flotation machine adopts a rotor with a single-wall backward inclined blade and a double inverted cone-shaped structure, a porous cylinder gas distributor and a movable bubble pushing device which is formed by two reverse bubble pushing plates and hung in the middle of a groove, wherein the movable bubble pushing device, the groove body, a stator, a rotating shaft, a transmission device and other parts form the whole flotation machine. Compared with the common flotation machine, the flotation machine has the advantages of high recovery rate of useful minerals, low power consumption, long service life of the rotor and the stator, low consumption of easily ground parts and the like.
Description
The invention belongs to the mineral floating separation equipment, be used to sort non-ferrous metal, ferrous metal and nonmetallic mineral.
4247391) and the OK flotation device of Finland FLOTATION SEPARATION equipment has some kinds, and Dao Er-Ao Liwo flotation device (U.S. Patent number: of the U.S. is wherein arranged with the similar flotation device of the present invention.
Dao Er-Ao Liwo flotation device is made up of swirl shape rotor, hanging type stator and the transmission device of " U " shape section cell body, single wall radial blade.This machine rotor central upper 1/4 place is an air chamber, and this chamber is communicated with interlobate space by macropore, the gas dispersion weak effect; Rotor center bottom 3/4 is occupied by wheel hub, the ore pulp amount that influence enters impeller by the rotor lower end; Do not have foam pushing device, ore pulp surfactant foam translational speed is slow, influences floatation indicators.
The OK flotation device is made up of swirl shape rotor, radiant panel linear leaf stator and the transmission device of " U " shape section cell body, " V " blade.This machine power consumption is higher, and rotor is complicated heavy, and the manufacturing cost height does not have foam pushing device, and ore pulp surfactant foam translational speed is slow, influences floatation indicators.
For improving existing similar FLOTATION SEPARATION equipment performance, to improve sorting mineral efficient, reduce function, reduce manufacturing cost and use cost, increase economic efficiency.Flotation device of the present invention is proposed.
Fig. 1 is a flotation machine for separating mineral, has shown the overall of the assembling situation of each parts that constitutes flotation device and flotation device.
Fig. 2 is a rotor-stator structure, has shown the assembling situation of rotor, stator, air distributor and stator, main shaft, and their structure.
Fig. 3 is a foam pushing device, has shown that foam pushing device foam pushing device in Fig. 1 is in the situation of dotted line position.
Flotation machine for separating mineral of the present invention is as shown in Figure 1 by holding ore pulp " U " shape section cell body (11), the two inversed taper platform shape rotors (14) of single wall hypsokinesis blade, perforated cylinder gas distributor (15), the unsettled stator (16) of radial blade, be suspended on the reverse activity foam pushing device (17) of cell body (11) middle upper portion, and hollow shaft (18), bearing body (19), crossbeam (20), motor (21), transmission device (22), bend pipe (58), the compositions such as gas control valve (59).
During flotation device work, rotor (14) passes through transmission device (22) and hollow shaft (18) driven rotary by motor (21), ore pulp enters space between rotor blade by bottom land (13) by rotor (14) lower end, meanwhile the air from air blast (not having figure) passes through crossbeam (20) (double as airduct), bend pipe (58), gas control valve (59) and hollow shaft (18) enter gas distributor (15), enter space between rotor blade by the aperture on the gas distributor wall then, ore pulp mixes the back with gas and is discharged by rotor top between blade, again through stator guiding and stable after enter in the groove in the main body ore pulp, the bubble that adheres to mineral grain rises to ore pulp surface (12) and goes up and form froth bed.Near rising bubble in the ore pulp of groove middle part and entrained ore pulp thereof, push away bubble plate top and be raised to the ore pulp surface when running into, formed a power that promotes foam to foam downflow weir (61) fast moving.Carrying the foam of concentrate discharges from foam downflow weir (61).Ore pulp enters next groove and selects or drain as discarded tailing from the groove bottom in the groove.
The present invention is characterised in that the rotor (14) that adopted the two inversed taper platform shape structures of single wall hypsokinesis blade, perforated cylinder gas distributor (15) and oppositely pushes away the movable foam pushing device (17) that is suspended on the groove centre that bubble plate (44) is formed by two.
Rotor (14) is made up of top board (23) and several blades (24) as shown in Figure 2.Top board (23) is circular, and the center is porose.Blade (24) extends downwards from top board (23), with radially become 30 ° of angles, blade inner edge (26) is the straight line of vertical top board (23), the broken line that outer rim is made up of epimere straight line (27) and hypomere straight line (28), and blade (24) forms shape wide at the top and narrow at the bottom.The quantity of blade is generally selected 6～8, and the width of blade is big or small and different according to tankage.The two inversed taper platform shapes of the outer formation of whole rotor (14), 15 °～25 ° of epimere cone angles are good with 20 ° of angles, the hypomere cone angle is 60 °～90 °, is good with 80 ° of angles.This rotor have raise send that the ore pulp amount is big, pressure head is low, power consumption is economized, advantages such as ore particle suspends in the groove.
Gas distributor (15) is made up of cylindrical wall (29), terminal pad (30) and base plate (31) as shown in Figure 2.Cylindrical wall (29) is gone up uniform many apertures (32), and hole diameter is 10～20 millimeters, is good with 12 millimeters, and the hole gross area equals 1.2～1.5 times of hollow shaft (18) endoporus area.Have the aperture more than 4 on the base plate (31), the aperture is less than the aperture on the wall.The length of gas distributor is 2/3 of rotor blade length, and diameter is 28% of a root diameter.The terminal pad of gas distributor (30) is clamped between flange (33) and rotor (14) top board (23).Adopt gas distributor (15) to make the gas and the ore pulp that enter between rotor blade (24) that bigger contact area be arranged, help gas to be dispersed in the ore pulp with the form of microvesicle.
Foam pushing device (17) oppositely pushes away bubble plate (44) by two as shown in Figure 3 to be formed, and is suspended in the middle of the groove versatilely.Push away be welded with on bubble plate (44) two oval rings (45), two three square rings (46), on strengthen angle steel (47) and reinforcement angle steel (48) down.Push away bubble plate (44) by last annulus (45) and connecting rod (49) be suspended on hook (51) (Fig. 1) on, during work pull bar (50) is suspended to hook (52) (Fig. 1) on, make push away the bubble plate (44) be in solid line device among Fig. 1, two angles that push away the bubble plate are 60 °～120 °, are good with 90 ° of angles.During maintenance pull bar (50) is taken off and is suspended on the hook (53) from hook (52), make to push away and steep plate and be in dotted line position among Fig. 1.This foam pushing device (17) has been accelerated ore pulp surfactant foam translational speed, helps improving sorting index, does not influence service work again.
It is good that flotation device of the present invention has the performance of sorting, low in energy consumption, advantage such as simple in structure and manufacturing and use cost are low.Show that through the copper mineral flotation test the present invention compares with general flotation device, guaranteeing that under the concentrate grade same case, copper recovery improves 1%, power consumption saves 50%, prolongs one times the service life of rotor and stator, easily grinds part consumption expense and saves 80%.
