Description
Technical field
The present invention relates to a kind of froth flotation machine that in the slurry flotation that separates useful constituent and tailings, uses, more particularly, relate to centrifugal foam flotation method and jet method for floating in conjunction with the coarse scavenging flotation machine that reclaims valuable tiny mineral and metallic particles.
Background technology
Froth flotation is a kind of known tiny material that will pulverize from being the method for separating the ore pulp of medium or the suspension with water.The pellet that hope is reclaimed from ore pulp can be handled with chemical agent, and it is hydrophobic that they are become, and ore pulp is sneaked into or sprayed into to a kind of gas that will be generally air with the form of bubble.Bubble contacts with hydrophobic pellet, and they are carried into the ore pulp surface, forms the stable foam of one deck.The foam that contains the pellet that floats is recovered as enrichment or floating product, and various hydrophilic materials then are left and sink in the ore pulp, are discharged then.
At present, in the flotation technology, utilize the flotation device of froth flotation fabrication techniques that two classes are arranged usually: a class is centrifugal agitation type flotation machine, and the inflation of ore pulp and stirring all lean on the centrifugal machine agitator to finish; It represents type is the SF type flotation machine of ore deposit, Beijing institute design, this machine has mainly adopted double-deck impeller blade, has strengthened the systemic circulation of bottom ore pulp in the cell body, and recycle slurry stream in bottom has centrifugal propelling movement swabbing action in the stator vane district, it is lower to have rotating speed, advantages such as power consumption province.Another kind of is jet flotation machine, utilizes the ore pulp injection to produce negative pressure principle and forces to suck air, produces foam and carries out flotation, and it has the air of the special use of need not being provided with to be pressed into equipment, the advantage that power consumption is economized; It represents type is that Chinese invention patent 02290087.X discloses a kind of " high-efficiency jet flotation device ", this machine mainly is made of ore inlet chamber, ore pulp shower nozzle, air chamber, downcomer, cell body, support and discharger, the downcomer outlet is connected with the ore pulp kick plate, ore pulp can have been increased the air dispersion degree and improve output with madial wall under the speed directive groove of 3-5m/s.Also have inventor's application for a patent for invention " high-efficiency jet flotation device " 200620052106.7 to State Intellectual Property Office's proposition, also belong to this type on August 28th, 2006.
Above-mentioned two class flotation devices respectively have not enough point, centrifugal agitation type flotation machine is because bottom recycle slurry stream can only impale socket joint propelling movement effect at impeller outer, its auxiliary centrifugal suction is starched, air-breathing usefulness is limited, moreover, circulation ore pulp in bottom can only contact with top slurry stream, bubble in the impeller periphery, therefore the flotation intensity of valuable mineral is still not high in the bottom slurry stream, and flotation yields poorly.Though and jet flotation machine output is big, because they are that ore pulp and Air mixing process and separation process are concentrated in the container, aeration quantity is excessive around the mineralising storehouse, cause ore pulp magic flower tail, the ore deposit discharger is stopped up by coarse sand easily and causes deadlock, influences flotation efficiency.Being exactly above-mentioned two class flotation devices in addition can not realize automatic control to the control adjustment of concentrate liquid level in cell body mine tailing liquid level and the flotation bucket.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the defective that exists in the above-mentioned technology, and a kind of coarse scavenging flotation machine is provided; This coarse scavenging flotation machine is roughly selected or is scanned applicable to the valuable mineral of variable grain level ore pulp, in running, can control and keep the liquid level of each work nest automatically, have low in energy consumption, concentration ratio is big, the rate of recovery is high, the installation area little, the characteristics that day output is big.
The technical scheme that the present invention will deal with problems is as follows:
A kind of coarse scavenging flotation machine comprises ore pulp storage tank, mechanical centrifugal part and jet part; The centrifugal part of machinery is a centrifugal agitation type flotation machine, and rotating shaft, impeller are arranged in its cell body, overlaps cylindrical central sleeve in the rotating shaft, and there is centrifugal cover at the impeller edge, and cylindrical central sleeve below connects air conduit and the stock inlet that draws from the liquid level top; On the cell body notch, also establish concentrate froth paddle and concentrate foam tank; Described jet part is made up of fluidic device and foam storehouse, and foam storehouse upper wall is connected to froth overflow channel, and bottom, foam storehouse has bottom valve to connect the ore pulp storage tank, and the ore pulp storage tank connects fluidic device by mortar pump, high-voltage tube again; The bottom, foam storehouse of jet part is connected with the stock inlet of mechanical centrifugal part; The centrifugal part of machinery connects the liquid level regulating box by the ore pulp Returning outlet, and the pulp returning port of liquid level regulating box bottom is connected with the ore pulp storage tank; All be respectively equipped with the mineral syrup liquid self controller separately in ore pulp storage tank, mechanical centrifugal part and jet part.
The present invention integrates the advantage of jet and two kinds of flotation devices of mechanical centrifugal stirring, ore pulp is by the valuable mineral of the first enrichment part of jet part fine grained level, when the valuable mineral of coarse granule level is not by enrichment in another part, carry out enrichment by the centrifugal stirring of machinery again, the valuable mineral of the variable grain level in the ore pulp is all had good flotation effect; Compare with existing general SF type flotation machine, concentration ratio of the present invention, the rate of recovery will improve 3-6 doubly, and the while is energy savings greatly, in addition, equipment itself is easy and simple to handle, can also multiple devices be connected by a pass-through, makes day output can accomplish that the unit hundreds of is to last kiloton; One of the present invention can replace existing agitated flotation cell 3-4 platform, has dwindled the installation area of equipment, is applicable to that the valuable mineral of variable grain level ore pulp is roughly selected or scanned.
