The invention discloses a flotation machine and a flotation method, and aims to solve the problems that a traditional flotation machine is small in air suction amount and large in energy consumption and does not have the abilities of air self-suction or ore pulp self-suction. The flotation machine comprises a tank body (5). A false bottom (9) is installed in the tank body and connected with a flow guide tube (8), the flow guide tube is connected with a main shaft (4), an impeller (7) is installed on the lower portion of the main shaft, the main shaft is sleeved with a center sleeve (3), an air suction pipe (2) is installed on the center sleeve, the lower portion of the center sleeve is connected with a cover plate (6), and the main shaft is connected with a belt pulley (1). The flotation machine and the flotation method are used for ore separating flotation.
Description
technical field:
the present invention relates to a kind of flotation device and method for floating.
background technology:
in the fields such as flotation of the separating flotation of polymetallic ore, the comprehensive utilization of complex ore, iron ore flotation and non-metallic ore and coal, all obtained achievement.The theoretical foundation of various floatation process is substantially identical, and ore particle, because of the hydrophobic property on self surface or hydrophobic (close gas or the oil) characteristic obtaining after floating agent effect, can be assembled at liquid-gas or water-oily interface.At present most widely used is froth flotation method.Ore makes various mineral disaggregations become monomer particle through broken with grinding, and makes granular size meet floatation process requirement.Ore pulp after ore grinding adds various floating agents and stirs mediation, makes and mineral grain effect, to expand the intergranular floatability difference of different minerals.The ore pulp mixing up is sent into flotation cell, stirs inflation.Ore particle in ore pulp contacts, collides with bubble, and the ore particle that floatability is good optionally adheres to bubble and is carried to rise becomes the mineralized froth layer of gas-liquid-solid three phase compositions, through mechanical scraping or overflow from mineral slurry level, then dewaters, is dried to concentrate product.The mineral grain such as floaty gangue, does not discharge as product from failing from flotation cell bottom with ore pulp.Traditional flotation device exists that inspiratory capacity is little, the problem such as large that consumes energy, and does not possess the ability of air self-priming, ore pulp self-priming.
summary of the invention:
the object of this invention is to provide a kind of flotation device and method for floating.
above-mentioned object realizes by following technical scheme:
a kind of flotation device, its composition comprises: cell body, the false end, is installed in described cell body, the described false end, is connected with mozzle, and described mozzle is connected with main shaft, in described main shaft bottom, impeller is installed, central tube is enclosed within described main shaft outside, at described central tube, put air intake duct is installed, the bottom of described center jacket casing is connected with cover plate, and described main shaft is connected with belt wheel.
described flotation device, described impeller is provided with the impeller blade with BI two-sided blade, and described impeller blade comprises blade, lower blade, and described cover plate has circulation port.
a method for floating for flotation device, motor is with drive shaft by V, makes the vane rotary of its underpart; By the impeller with BI two-sided blade, realize two circulations of ore pulp in groove; During vane rotary, the ore pulp in upper and lower impeller cavity produces centrifugal force and is thrown toward surrounding under the effect of upper and lower blade, makes formation negative pressuren zone in upper and lower impeller cavity; Meanwhile, the circulation port of the ore pulp on cover plate top on cover plate is inhaled in upper impeller cavity, forms ore pulp cocycle; And the three-phase mixture that the ore pulp being thrown out of in lower impeller cavity throws away than blade is than great, thereby centrifugal force is larger, movement velocity decay is slower, and the three-phase mixture that blade is thrown away has produced additional motive force, its centrifugal force is increased, thereby improved the vacuum in upper impeller cavity, played auxiliary getter action; When lower blade throws away ore pulp to surrounding, its underpart ore pulp supplements to center, thereby forms the lower circulation of ore pulp; And air is inhaled into impeller cavity through air intake duct, central tube, mix mutually with the ore pulp being inhaled into, form a large amount of tiny bubbles, after cover plate current stabilization, disperse uniformly, in groove, forms mineral laden bubble; Mineral laden bubble floats up to froth bed, by scraper plate, scrapes froth pulp.
beneficial effect:
1. the present invention has that inspiratory capacity is large, few feature consumes energy.
2. the present invention has air self-suction, self-priming ore pulp ability, and horizontal arrangement, does not need foam slurry.
3. impeller circumferential speed of the present invention is low, vulnerable part long service life, and the gap between impeller and cover plate is larger, and impeller and cover plate affect less because wearing and tearing increase gap on inspiratory capacity.
4. in groove of the present invention, ore pulp carries out upper and lower two circulation by the fixing type of flow, is conducive to the suspension of coarse grain mineral.That every groove has concurrently is air-breathing, midge and flotation triple functions, has flotation circuit of one's own, does not need any auxiliary equipment, and horizontal arrangement, is convenient to the change of flow process.
5. ore pulp circulation of the present invention rationally, can reduce coarse sand precipitation to greatest extent.Impeller is with the blade up and down of BI.Blade produces ore pulp cocycle, and lower blade produces under ore pulp and circulates.
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present invention.
the specific embodiment:
embodiment 1:
a kind of flotation device, its composition comprises: cell body 5, the false end 9, is installed in described cell body, the described false end, is connected with mozzle 8, and described mozzle is connected with main shaft 4, in described main shaft bottom, impeller 7 is installed, center jacket casing 3 is in described main shaft outside, at described central tube, put air intake duct 2 is installed, the bottom of described center jacket casing is connected with cover plate 6, and described main shaft is connected with belt wheel 1.
embodiment 2:
according to the flotation device described in embodiment 1, described impeller is provided with the impeller blade 12 with BI two-sided blade, and described impeller blade comprises blade 10, lower blade 11, and described cover plate has circulation port.
embodiment 3:
the method for floating of above-mentioned flotation device, motor is with drive shaft by V, makes the vane rotary of its underpart; By the impeller with BI two-sided blade, realize two circulations of ore pulp in groove; During vane rotary, the ore pulp in upper and lower impeller cavity produces centrifugal force and is thrown toward surrounding under the effect of upper and lower blade, makes formation negative pressuren zone in upper and lower impeller cavity; Meanwhile, the circulation port of the ore pulp on cover plate top on cover plate is inhaled in upper impeller cavity, forms ore pulp cocycle; And the three-phase mixture that the ore pulp being thrown out of in lower impeller cavity throws away than blade is than great, thereby centrifugal force is larger, movement velocity decay is slower, and the three-phase mixture that blade is thrown away has produced additional motive force, its centrifugal force is increased, thereby improved the vacuum in upper impeller cavity, played auxiliary getter action; When lower blade throws away ore pulp to surrounding, its underpart ore pulp supplements to center, thereby forms the lower circulation of ore pulp; And air is inhaled into impeller cavity through air intake duct, central tube, mix mutually with the ore pulp being inhaled into, form a large amount of tiny bubbles, after cover plate current stabilization, disperse uniformly, in groove, forms mineral laden bubble; Mineral laden bubble floats up to froth bed, by scraper plate, scrapes froth pulp.
