Abstract
The invention is a flotation machine for mineral separation with slurry absorbing capacity and flotation function, which is characterized in that the structure of an impeller adopts a flotation machine formed by a structure with a back-tilting double-blade, compared with the existing A-plastic flotation machine, the flotation machine has the advantages of electricity consumption saving, large air suction amount, light impeller abrasion, good flotation index and the like, and is suitable for separating and sorting nonferrous metals, ferrous metals, nonmetallic minerals and chemical raw materials.
Description
The present invention is a kind of ore dressing flotation device, belongs to International Patent Classification (IPC) B03D class scope, is used to separate non-ferrous metal, ferrous metal, nonmetallic mineral and industrial chemicals, extracts a kind of floatation equipment of valuable mineral.
At present both at home and abroad the flotation device kind of the separating mineral that adopts is a lot, and can to inhale the flotation device that slurry again can flotation be the A type flotation machine but belong to.This machine is made up of the parts such as single blade, impeller and stator of motor, air intake duct, central tube, main shaft, band arranged radially.Shortcomings such as this machine exists the energy consumption height, damage in impeller is fast, inspiratory capacity is low, ore dressing weak effect.The objective of the invention is to overcome the deficiency of A type flotation machine, the flotation device that energy consumption is low, wear and tear less, can improve mineral processing index is provided.
Fig. 1 is flotator structure figure of the present invention.
Fig. 2 is the blade wheel structure figure of flotation device of the present invention.
Fig. 3 is the stator structure figure of flotation device of the present invention.
Ore dressing of the present invention with the structure of flotation device as shown in Figure 1, it is made up of motor (1), air intake duct (2), central tube (3), cell body (4), impeller (5), stator (10), mozzle (7) and the vacation end (8).Motor (1) is connected with cell body (4) with bearing body (14) by means of the motor frame with main shaft (9).Impeller (5) is fixed on the lower end of main shaft (9), and stator (10) is used bolt tightening with being connected of central tube (3).When the flotation device volume less than 10 meters
3The time, do not establish the mozzle (7) and the false end (8).
Flotation device of the present invention is characterised in that impeller (5) is the BI double blade structure, and the inclination angle forward of stator vane is 40～50 °.
The structure of impeller (5) is made up of blade (11), lower blade (13) and the impeller disk (12), as shown in Figure 2 through integral casting forming.Upper and lower blade all adopts BI, and the oblique angle that retreats is 25～35 °; The quantity of blade respectively is that 6, the ratio of height are 2.0～1.5 up and down.
The structure of stator (10) as shown in Figure 3, periphery is provided with the blade at several 40～50 ° of angles that turn forward, blade quantity is different with the amount of capacity of flotation device, and is generally comparatively suitable with 12～18.
When the capacity of flotation device greater than 10 meters
3The time, set up the mozzle (7) and the false end (8), the false end (8), keep certain distance with bottom land, and it has several circulation ports, to increase the range of DO of ore pulp, prevents the precipitation of coarse grain mineral.
Ore dressing of the present invention is as follows with the operation principle of flotation device: rotated by motor (1) drive shaft (9) impeller (5), blade (11) on impeller this moment (5) promotes the ore pulp rotation and produces centrifugal force, make impeller cavity produce enough vacuum, ore pulp and air suck in impeller cavity by circulation port on central tube and the stator and air intake duct, and with the form of gas-liquid mixture to around throw away.Meanwhile, during impeller (5) rotation, lower blade (13) also makes ore pulp produce centrifugal force, the suction its underpart ore pulp to around dish out, the proportion of this ore pulp is more great than the ratio of the gas-liquid mixture that blade throws away, and movement velocity decay is slower, a kind of additional motive force of gas-liquid mixed deposits yields that blade is dished out, the corresponding vacuum that improves last impeller cavity plays auxiliary getter action.In addition, when impeller rotation, ore pulp is by impeller cavity down the time, the ore pulp of its underpart by around replenish to the center, formed ore pulp circulation in the impeller bottom.In the flotation device of big volume, again to cocycle, flow rate of pulp is big in the passage under the vacation end by mozzle (7) and the passage ecto-entad at the false end (8) for ore pulp, is enough to make the coarse grain mineral suspension and does not precipitate.
Ore dressing of the present invention has advantage such as save power consumption, inspiratory capacity is big, damage in impeller is light and floatation indicators is good with flotation device.The results showed no matter be used for the ore dressing of plumbous zinc ore or iron ore, its sorting index all improves, economize on electricity 15～30%.Flotation device of the present invention can not have the flotation device coupling of inhaling the slurry ability with other yet mineral is carried out detached job except that being applied to separately the separating mineral, and power savings is more obvious.
Claims (1)
1, a kind of by motor (1), air intake duct (2), central tube (3), cell body (4), mozzle (7), the flotation device that the sorting mineral that the false end (8) and main shaft (9) are formed is used, its invention is characterised in that impeller (5) is by the impeller disk (12), blade (11) and lower blade (13) are formed, blade and lower blade adopt BI, thereafter degree of tilt is 25 °～35 °, blade and lower blade aspect ratio are 1.5～2.0, and be fixed on the lower end of main shaft (9), stator (10) periphery is provided with the blade (6) at the 40 °～50 ° of angles that turn forward, and being fixed on the lower end of central tube (3), impeller and stator are complementary.
