detailed description of the invention
Be described further below in conjunction with accompanying drawing:
Flotation column in the present embodiment has flotation column main body, flotation column main body upper end has overfall, lower end to have slag-drip opening, feeding mouth is squeezed into the ore pulp of inflating in advance after mineralising in flotation column main body, the bottom of flotation column inside is provided with adjustable inflatable component 4, and adjustable inflatable component 4 is by support member 3 fixed constant-current plates 2.
Adjustable inflatable component 4 is made up of the above disc for air inflations of three or three, and the present embodiment is taking the adjustable inflatable component of three disc for air inflations as example.The cylinder that there is no bottom surface that the first disc for air inflation 5 is hollow, damaged surface has to cause lacks first filling channel 10, the first disc for air inflation and the power drive device of an adjusting position (not shown) that is connected in height, this driving arrangement can be realized by various structures in prior art, as stepper motor, an air supply opening is located at the lower end of the first disc for air inflation; The second disc for air inflation is the cylinder of not going up bottom surface, and it is set on the first disc for air inflation 5, and the first disc for air inflation 5 can drive the second gas fill dish to continue to rise rising to after predetermined altitude, and the second disc for air inflation has and causes few second filling channel 10; The 3rd disc for air inflation 7 is the cylinder of not going up bottom surface, and it is set on the second disc for air inflation 6, and can be filled dish by the 3rd gas spacing and carry on can not continuing rising to after predetermined altitude for the second disc for air inflation 6, and the 3rd disc for air inflation has and causes few the 3rd filling channel 11.Between the first disc for air inflation and the second disc for air inflation, be provided with sealing ring, between the second disc for air inflation and the 3rd disc for air inflation, be provided with sealing ring.
Be preferably, the first filling channel, the second filling channel are horizontally disposed with, and the 3rd filling channel arranges obliquely.
Suppose under identical air pressure, in the unit interval, the air demand of the first disc for air inflation is X, and the air demand of the second disc for air inflation is Y, and the air demand of the 3rd disc for air inflation is Z.Due to the diameter of three disc for air inflations not etc., in general X, Y, tri-values of Z are unequal, are preferably Z>Y>X.
As shown in Figure 3, adjustable inflatable component is in the time of the first state, and the first to three disc for air inflation is all in same level, and now flotation column aeration quantity is X.Air supply opening is set in the first disc for air inflation can only pass through the first disc for air inflation air feed, and the gas of the first disc for air inflation supply enters flotation column after by the first to three filling channel.
As shown in Figure 4, adjustable inflatable component is in the time of the second state, the first disc for air inflation driven member promotes, the second disc for air inflation and the 3rd disc for air inflation are in same level, now, flotation column air demand is X+Y, and air supply opening can be the first and second disc for air inflation air feed simultaneously, the first disc for air inflation the gas of confession directly entered into flotation column, the second disc for air inflation institute supplied gas by second and the 3rd filling channel enter flotation column.Under this state, not only air demand changes to some extent, and the also increase thereupon of effective contact area of charger and ore pulp, and this made within the shorter time, more effective change air-fill levels.
As shown in Figure 5, adjustable inflatable component is in the time of the third state, the first disc for air inflation drives on the second disc for air inflation and carries, the first to three disc for air inflation is respectively on three different height, now air demand is X+Y+Z, and the constant voltage air-flow that air supply opening provides directly enters flotation column by three disc for air inflations simultaneously, and charging efficiency is now for the highest, charger and ore pulp contact area have also reached maximum, i.e. gas and ore pulp contact area maximum.
Stabilier 2 is fixed on by support member on the first disc for air inflation of adjustable inflatable component, when adjustable inflatable component is in second or when the third state, stabilier 2 also rises thereupon, now ore pulp needs more turbulent flow that gas and mineral aggregate are clashed into and combination, and the too early ore pulp that makes enters the combination that current stabilization region is unfavorable for bubble and ore particle.
Adjustable inflatable dish is in use adjusted adjustable inflatable component according to the real-time condition of ore pulp, is specially:
1) after flotation starts, adjustable inflatable component is air feed under the first state, inductor is measured foam recovery amount/concentrate yield of flotation column overfall, if the yield in the unit interval is ascendant trend, adjustable inflatable component becomes the second state from the first state;
2), again through a unit interval, if yield is still ascendant trend, adjustable inflatable component becomes the third state from the second state; If yield maintains an equal level with the value recording before, keep the second state.
3), again through a unit interval, if yield is downward trend, adjustable inflatable component is adjusted to low aeration quantity state from high aeration quantity, until reduce to the first state.
The trend of above-mentioned yield can have multiple formula or method to calculate, wherein conventional computational methods are measure and compare at two yields corresponding to time end points of unit interval, if after any yield be greater than before any yield, be ascendant trend; The yield of 2 equates for aeration quantity should keep; The yield of rear point is less than the yield of front point, is downward trend.
Although the disclosed adjustable inflatable flotation column relating to has been carried out to special description with reference to embodiment; embodiment described above is illustrative and not restrictive; in the situation that not departing from the utility model scope, all variations and amendment are all within protection domain of the present utility model.
