The specific embodiment
A kind of basic embodiment is below provided, specific embodiment of the invention is not caused to restriction;
Comprise induction part and the pressure-air automatic switch steam generator 13 that is distributed in tank therefor bottom, in tank therefor, be distributed with ore pulp riser tubing 12, ore pulp elevator bearing block 5 belows have ore pulp to promote impeller 10, and ore pulp elevator Hollow Transmission Shafts 8 tops are raised arbor bearing and auxiliary framework 22 is fixed; Ore pulp enters pipeline 18 middle part circulation port two pipes and is connected with ore pulp deflector 11; Ore pulp disperses slewing circle wheel 9; There is ball ore pulp vent valves 20 foam tank 15 belows; Ball ore pulp vent valves 20 is with valve positioner 21.
The further technical scheme of the present invention is, the described pressure-air automatic switch disperser 13 of getting angry has more than three layers, has a plurality of air dispersion automatic shutters hole on it.
The further technical scheme of the present invention is, described in enter that ore pulp enters pipeline 18 and ore pulp riser tubing 12 connects as one, circulation port is with ore pulp deflector 11 outward, described ore pulp riser tubing 12 machine transmission shaft component tops are connected with belt pulley.
The further technical scheme of the present invention is, described container also comprises mine tailing overflow pipe 14, and the inner lower opening of mine tailing overflow pipe 14 is connected with pressure-air air inlet pipe 17.
The further technical scheme of the present invention is, described pressure-air automatic switch steam generator 13 connection extraneous air imports.
The further technical scheme of the present invention is, there are pressure-air import and gauge tap in pressure-air air inlet pipe 17 tops.
The further technical scheme of the present invention is, also comprises the revolving emersion foam that is positioned at tank therefor top and scrapes bubble device 4.Floating and enriching concentrate foam is scraped, guarantee concentrate enrichment grade.
Flotation fuselage 19 is cast by steel plate or armored concrete.
Air feed is greater than 4 kilograms of air pressure by air compressor machine and supplies required compressed air.
Pressure-air automatic switch steam generator 13 by iron pipe, wear sour jujube rubber tube and form, automatic switch airway dysfunction, this generator can be opened inflation when pressure-air is inflated, and after shutdown, automatically closes, and prevents that muddy water from entering in steam line.
Ore pulp dispersion slewing circle wheel 9, is arranged on lifting turning cylinder (rising slurry air inlet pipe) and above a plectane, consists of, and its function is to disperse upper and lower ore pulp in ore pulp top layer, in acceleration flotation thing and bubble.
Mine tailing overflow and liquid level are controlled by aerating device.Mainly by pipeline gas tube, formed.
Emersion foam is scraped bubble device 4 foam of floating and enriching is scraped in time.
Floatation equipment operation principle:
All kinds of--200 orders need flotation pulp to enter ore pulp outward to enter in pipeline 18, and ore pulp enters pipeline 18 and joins with deflector epimere pipe is straight-through, and ore pulp enters in pipe disc wheel and rotates and ore pulp is distributed to floatation equipment groove under doing and holds ore pulp top layer in body.
Open the valve that each needs inflation, in floatation equipment, need the position of inflation to inflate.
Open the ore pulp machine that promotes, ore pulp elevator impeller 10 rotates, and in ore pulp suction line, air also enters in pipe simultaneously, ore pulp and bubble floating work.
At the ore pulp that has beneficiation reagent, enter under the state of working in floatation equipment, ore pulp deadweight is fallen, by upper and deadweight sink to bottom, follow hydrophobic mineral also heavy from top to bottom, in floatation equipment bottom, because there being pressure-air automatic switch steam generator 13, air from bottom to top rises to when liquid level is encountered hydrophobic mineral on the way and is floated in liquid level foam by air bubble band.Not by the mineral of liquid level on air band, while dropping to floatation equipment conical lower portion, now by ore pulp elevator impeller 10, be drawn into and carry in slurry pipe, carrying slurry pipe inside has large quantity of air, and all mineral particulates of ore pulp, are all with liquid level, wherein hydrophobic mineral enter foam, enter froth bed and be scraped, hydrophilic mineral continue to stay in groove, have so just reached the separated object of hydrophobic mineral and hydrophilic mineral.
Floatation equipment mine tailing overflow pipe 14 below is added with compressed air, and valve is controlled aeration quantity size, strengthens aeration quantity, can accelerate mine tailing flow velocity and flow, thereby realize the adjustment of mineral syrup liquid.
Under shutdown situation, each air duct aerating device can cut out automatically, does not have muddy water and enters in gas ducting; after shutdown, ore pulp all sinks to bottom, because elevator is unitary part; the particular design of ore pulp elevator impeller 10, even all covered in silt, also can easily start; having under air auxiliary; by silt sediment, air movement starts to suspend and flows, and restarts flotation work very soon; this floatation equipment motor is positive and negative all can ore dressing, but preferably ore pulp direction of improvement transfers to.
Inflation air compressor machine, compressed air pressure is greater than 4Kg, and pressure is better greatly.
In conjunction with Fig. 2;
Adopt after invention, mineral floating adopts, and a vat is roughly selected three vats and scanned, and (can not adopt cleaner cell or selected with a sulculus) altogether 4 grooves can reach and be satisfied with mineral recovering effect.
Originally adopt conventional agitated flotation cell technique flotation mineral, need to pass through one roughing 4 grooves, scan 12 grooves three times, selected 4 grooves, amount to 20 grooves.20 groove technological processes are numerous and diverse, and consumes energy is many, complicated operation maintenance capacity.
