Description
Technical field
The utility model is related to a kind of cancellation element of flotation froth, belongs to mineral processing flotation technology field.
Background technology
Flotation is played as one of current main technique of preparing means in terms of processing particulate and fine grain teeth cloth ore
Highly important effect.The handling process of current zinc oxide ore mainly includes vulcanization-amine method, heating vulcanization-xanthate method, fat
Sour direct flotation method, flocculation-floatation etc..Can also be using weight-floating joint, magnetic-floating joint for some oxidase complex zinc ores
Sorted etc. mode.Wherein, vulcanization-amine method is because without heating, preferably, metal recovery rate height is waited and obtained flotation effect
Most of zinc oxide select the application of factory, but the method is more sensitive to sludge and solubility salt, and not only reagent consumption amount is big, and
The big viscosity of froth bed thickness of formation is big, and mobility is poor, it is difficult to eliminate so that can not be effectively enriched with by floating mineral, very
To the phenomenon for overflow or " race groove " occur, its recovery index in the industry is also tended to 50% or so.Main reason is that mistake
Thick froth bed prevents further enrichment and the floating of follow-up target minreal, and the particle that has floated of part due to not by
Discharge, is pulled and come off from bubble by ore pulp in time.The seriousness of this problem is not only to fail to limited zinc ore money
Source is made full use of, and the also production practices to enterprise cause no small economic loss.
On the method for froth breaking, routinely use and sprayed with high-pressure washing water, i.e., in one end of foam tank with height
Press hydraulic giant or be rinsed in the way of water pipe, although the elimination to foam plays a role, but water consumption is big, influences ore deposit
Concentration is starched, certain influence is caused on follow-up dewatering operation, and it also requires constantly regulating and controlling according to foam state to water.
It is another, it is to carry out froth breaking by adding defoamer, but the method not only increases production cost, and environment is polluted, new medicament
Addition flotation environment can also be impacted, or even initial flotation conditions of destruction etc..
The sprinkler head of conventional foam groove one end is improved to high-pressure atomization spray by the patent of Application No. 201510581438.8
Mouth, so as to form fan-shaped high-pressure water mist, though reducing water consumption and energy consumption to a certain extent, fan-shaped water smoke is to long and narrow square
Shape foam tank area of effective coverage is small, and rinse capability is limited.
A kind of centrifugation cartridge type flotation froth groove of the Patent design of Application No. 201220240162.9, i.e., with centre axis
Dynamic scroll sheet high-speed rotation, foam to top, which falls, carries out centrifugal motion after rectangular channel, by top flushing water and centrifugal force
Effect make bubble burst, the method major defect is that cylindrical foam tank is difficult to effectively dock with the overflow section of flotation device,
It is difficult to effectively collect foam, and the connection inconvenience of central shaft and motor.
Accordingly, it would be desirable to for flotation froth amount it is big and foam is difficult disappear the problems such as propose effective technical scheme.
The content of the invention
The utility model be for zinc oxide ore and other Ores it is other during the foam difficulty that occurs disappear problem and propose
A kind of flotation froth cancellation element, can effectively solve that amine collector occurs in floatation process because foam volume is big, glue
Degree is big, the reason such as poor fluidity and the low problem of the target minreal rate of recovery that causes, to making full use of limited resources and increase to look forward to
Industry benefit is significant.The utility model is achieved through the following technical solutions.
A kind of cancellation element of flotation froth, including superposed foam collecting tank 2 and the text for connecting foam collecting tank 2
Venturi 5, the top surface of cell body 3 of foam collecting tank 2 is uniformly provided with sprinkler head spray orifice 1, and cell body 3 is by the square groove on top with
The cone tank composition in portion, taper trench bottom is provided with gape 4, and Venturi tube 5 includes two equal straight lengths of two ends diameter, divided
Two contraction sections not being connected with straight length and the trunnion section by two contraction section connections, trunnion section pass through gape 4 and cell body 3
Connection.
Shrinkage ratio λ=d/D is 0.4~0.5 in the Venturi tube 5, and taper α is 1.6~2.0rad, and wherein D is venturi
Pipe straight length diameter, mm；D is trunnion section diameter, mm.
L1 in the Venturi tube 5:L2=2/6 ~ 4/6, wherein L1 are with first contraction section in aqueous medium flow direction
Length, L2 be with the length of second contraction section in aqueous medium flow direction.
The sprinkler head spray orifice（1）1 ~ 3 is uniformly provided with to be every square centimeter.
The operation principle of the cancellation element of the flotation froth is：
（1）Foam is scraped into foam collecting tank 2 by scraping plate of flotation machine, giant, foam will be inserted in sprinkler head spray orifice 1
In flushing water（Flushing water pressure is generally 0.4MPa）Effect is lower to enter cell body 3, due under width on the cone tank of the bottom of cell body 3
It is narrow so that foam is constantly assembled, drawn in；
（2）The high speed water of water pump generation is passed through to the straight length of Venturi tube 5, according to Venturi effect（Venturi
effect）, restricted flow flow velocity in the flow section by diminution increases, and produces low pressure near fluid, so as to produce
Suction-operated, after the foam of whereabouts is aggregated, under the synergy that stronger suction power and sprinkler head are sprayed, foam occurs broken
Go out, the foam slurry of generation drains into next process by aqueous medium conveying.
To ensure Venturi tube to there is stronger suction to act at gape, through determining, larynx section shrinkage ratio λ and taper α is shadow
The biggest factor of minimum pressure in speaking pipe, and reduce taper or increase shrinkage ratio vanishing and discharge beneficial to flotation froth.Really
Protecting import and export has larger pressure differential also to strengthen suction effect.When inlet and outlet pressure difference is 130kpa, minimum pressure can in pipe
Up to -400kpa or so.
The beneficial effects of the utility model are：
1st, for zinc oxide ore and foam volume be big and flotation of the difficult ore disappeared, the device can carry out foam effectively to gather
Collection, the stronger suction effect that spray effect and Venturi tube or similar device by foam tank upper end water are produced is broken to it
Go out and froth breaking, after the ore pulp after froth breaking enters in pipe, next process is delivered to by aqueous medium, the company of production operation is realized
It is continuous, stable and efficient.
2nd, this new method relies primarily on the stronger suction effect progress froth breaking that Venturi tube or similar device are produced, tool
Have simple in construction, easy to operate, efficiency high, the features such as easy-maintaining.
3rd, foam tank used in the device is upper rectangle inferior pyramidal, i.e., construction wide at the top and narrow at the bottom, with cylinder or other shapes
Foam tank compare, with being docked well with flotation device overflow section, the features such as effective area is big.
4th, the device is not required to addition defoamer or other new medicaments, is not required to set single foam cell, energy-conserving and environment-protective.
