Description
The utility model relates to a kind of improved flotation device.Be suitable for nonferrous metals ore and rare metal ore deposits such as flotation gold, copper, lead, zinc, tungsten, molybdenum.
Existing flotation machinery--flotation column, have simple in structure, make easy for installation, easy operating and maintenance, floor space is little, capital cost is low, especially saves advantages such as power.But the shortcoming of its maximum is an aerating device easily to be stopped up, thereby job insecurity, influences floatation indicators.Mineral processing in China factory uses maximum flotation devices at present, is the turbomachine agitation type flotation machine.This flotation device cost height, floor space is big, the capital cost height, consumed power is many, is not suitable for the flotation lean ore, and along with the development of mining, ore dressing, tellurian rich ore is fewer and feweri, and lean ore is more and more.For adapting to the needs of selecting and purchasing lean ore, must cut down the consumption of energy greatly, reduce capital expenditure, the task of this project just provides a kind of rotation pneumatic flotation cell, and it absorbs the advantage of flotation column, simple in structure, floor space is little, saves electric power, and at its drawback--aerating device easily stops up, increase anti-block apparatus, adopt inflation and mechanical agitation connection and effect, make working stability, to guarantee floatation indicators.
The novel task of this use is to realize like this--
A columniform cylindrical shell, top are equipped with mine-feeding equipment and concentrate foam launder, and the bottom is taper, link with the mine tailing lifting device, and cylindrical shell and mine tailing lifting device are formed a Communicating device.Mine-feeding equipment and ball-cock assembly combine, and realize that the rotation aerating device is installed in the taper position of cylindrical shell, mainly partly is made up of hollow cross cover, bearing block, sealing device, support etc. to ore deposit and control mineral syrup liquid.Hollow cross puts by outer close interior rule of dredging and has been covered with the inflation anti-block apparatus, the direction of inflation, or clockwise, or counterclockwise, all inflate anti-block apparatus, all keep same direction, the inflation anti-block apparatus, the pressure air interior with hollow cross cover communicates, and is made up of parts such as valve body, spring, steel balls.Pressure air is provided by air compressor, enters hollow cross cover inside by the rubber tube that passes within the mine tailing lifting device.When air pressure reaches when giving level pressure power, push the steel ball of inflation anti-block apparatus open, inject within the ore pulp.Ore pulp is to the recoil of air-flow, will impel hollow cross to be enclosed within rotation in the bearing on the support, thereby realize the rotation inflation.Not enough or when stopping to inflate, steel ball is closed gas circuit automatically by elastic reset when air pressure, air pressure and aeration quantity are regulated by air compressor machine.Like this, after ore pulp adding flotation medicine stirs, send in the tube by mine-feeding equipment, gravitate, slowly descend, compressed air becomes a large amount of micro-bubbles through the disperse of gas overcharging anti-block apparatus, and the diffusion while rotating is evenly distributed on the whole cross section of cylindrical shell and rises slowly, so, ore pulp becomes convection current with bubble-shaped, forms mineralized froth and can float mineral attached to bubble floating to ore pulp face, overflows voluntarily from foam launder, be concentrate, the not floating gangue of another part can not discharge or enter next operation from the mine tailing lifting device and handle attached on the bubble, is mine tailing.
Below in conjunction with accompanying drawing this project is done description further.
Fig. 1 is the structure principle chart of rotation pneumatic flotation cell.
Fig. 2 is the cutaway view of inflation anti-block apparatus.
With reference to Fig. 1, ［ 1 ］ is bearing, and cylindrical shell ［ 11 ］ is fixed on ［ 1 ］.The cylindrical shell main part is cylindrical, and the overstriking of hollow cross cover part is installed in the bottom, and the awl end has ring flange and mine tailing lifting device ［ 2 ］ to link.Fixed support ［ 5 ］ is equipped with at the circular cone position.Bearing block ［ 6 ］ is housed on the fixed support.Bearing block ［ 6 ］ bottom communicates with sebific duct ［ 3 ］, and sebific duct passes from mine tailing lifting device ［ 2 ］, joins with air compressor machine.On the bearing block, overlapping axle sleeve ［ 8 ］.Axle sleeve ［ 8 ］ can rotate on bearing block, and realizes sealing by sealing gasket ［ 7 ］, infiltrates therebetween to prevent ore pulp.The top of axle sleeve ［ 8 ］ is taper, and the pipe of shutting four orthogonal outer ends ［ 10 ］ is equipped with on top crisscross.［ 8 ］ fix by screw thread with ［ 10 ］, and it is fastening by nut ［ 9 ］, pipe ［ 10 ］ is by clockwise or counter clockwise direction, dredge outer close rule by the lining and arranging screwed hole, so that the inflation anti-block apparatus is installed,, correspondingly leave the installation side opening at the position of cylindrical shell overstriking for ease of loading and unloading pipe ［ 10 ］, pressured at ordinary times lid, sealing gasket and screw are sealed, and prevent the ore pulp seepage.
Mine-feeding equipment ［ 16 ］ and foam launder ［ 17 ］ are equipped with in top in cylindrical shell ［ 11 ］, and foam launder ［ 17 ］ bottom angled is beneficial to the ore deposit foam and flows out.Ball-cock assembly ［ 18 ］ is the control mineral syrup liquid.Liquid level rises and makes the ball float come-up, takes up slide plate and blocks the ore pulp outlet.Mine-feeding equipment ［ 16 ］ is linked to each other by joint ［ 15 ］ with outer tube ［ 14 ］, and outer tube ［ 14 ］ is equipped with the valve ［ 13 ］ of control mineral slurry flux.End leads to auxiliary equipment outside the valve--the mediation groove.
The upper end outlet of mine tailing lifting device ［ 2 ］ is lower than mine-feeding equipment ［ 16 ］, and is provided with mine tailing chute ［ 12 ］.The bottom outside of mine tailing lifting device ［ 2 ］ is provided with the plug of getting rid of mine tailing, blocks at ordinary times, can open during last person ore deposit.
With reference to Fig. 2, ［ 10 ］ are pipe, and ［ 20 ］ are spring, and ［ 21 ］ are steel ball, and ［ 22 ］ are valve body.Spring pressure can suitably be regulated by hollow adjustment screw.Hollow cross cover angular speed everywhere is identical, the place that decentre is far away more, and linear velocity is big more.Even for what guarantee to inflate, inflation anti-block apparatus decentre is far away more, adorns closely more.And, the installation site on four pipes also mutually mistake also avoid repetition.Like this, in rotary course, on the whole cross section, the bubble of disperse is quite uniform.The a part of overstriking of simplified this is in order to increase pipe ［ 10 ］, to guarantee that also there is sufficient bubble floating at the barrel place.
For this kind air flotation machine, ore pulp evenly sinks on whole cross section, and bubble evenly floats on whole cross section, guarantees abundant convection current, is the most important condition that realizes steady operation, improves the flotation rate. This realizes by corresponding device and controlling organization. Whole convection process is automatically to realize by the gravity of ore pulp and the buoyancy of bubble. Except the air compressor machine demand drives, main body is power consumption no longer, thereby saved a large amount of power, because this machine belongs to the deep trouth type flotation machine, only lower floor's ore pulp is stirred by hollow cross cover, and the upper strata ore pulp is bordering on stable sinking, is not stirred, be conducive to small bubble and in floating-upward process, accumulate gradually air pocket, form mineralized froth. Because above-mentioned all advantages, especially small investment, it is low to consume energy, and there is wide DEVELOPMENT PROSPECT in poor grade nonferrous metals ore and rare metal ore deposit that the most suitable flotation is more and more.
