Detailed description of the invention
It is described further below in conjunction with the accompanying drawings:
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, ore pulp after feeding mouth will inflate mineralising in advance is squeezed in flotation column main body, bottom within flotation column is provided with adjustable inflatable component 4, and adjustable inflatable component 4 is by support member 3 fixed constant-current plate 2.
Adjustable inflatable component 4 is made up of the disc for air inflation of three or more than three, and the present embodiment is as a example by the adjustable inflatable component of three disc for air inflations.First disc for air inflation 5 is the cylinder not having bottom surface of hollow, damaged surface has few first filling channel 10 of cause, the power drive device of the first disc for air inflation and one in height adjusting position is connected (not shown), this driving equipment can be realized by various structures in prior art, such as motor, an air supply opening is located at the lower end of the first disc for air inflation；Second disc for air inflation is the cylinder 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 to fill dish continuation rising after rising to predetermined altitude, and the second disc for air inflation has few second filling channel 10 of cause；3rd disc for air inflation 7 is the cylinder not going up bottom surface, and it is set on the second disc for air inflation 6, and it is spacing and carry on can not continuing that the second disc for air inflation 6 can be filled dish by the 3rd gas after rising to predetermined altitude, and the 3rd disc for air inflation has few 3rd filling channel 11 of cause.It is provided with sealing ring between first disc for air inflation and the second disc for air inflation, between the second disc for air inflation and the 3rd disc for air inflation, is provided with sealing ring.
Being preferably, the first filling channel, the second filling channel are horizontally disposed with, and the 3rd filling channel is arranged obliquely.
Assuming 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, in general X, Y, Z tri-value is unequal, preferably Z > Y > X.
As it is shown on figure 3, adjustable inflatable component is when the first state, the first to three disc for air inflation is all in same level, and now flotation column aeration quantity is X.Air supply opening can only be supplied by the first disc for air inflation in being set in the first disc for air inflation, 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 when the second state, first disc for air inflation driven member promotes, 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 supply simultaneously, first disc for air inflation the gas of confession entered directly into flotation column, the second disc for air inflation institute supplied gas by second and the 3rd filling channel enter flotation column.In this case, not only air demand changes, and effective contact area of charger and ore pulp increases the most therewith, and this makes, within the shorter time, more effectively to change air-fill levels.
As shown in Figure 5, adjustable inflatable component is when the third state, first disc for air inflation drives and carries on the second disc for air inflation, 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 is directly entered flotation column by three disc for air inflations simultaneously, and charging efficiency is now the highest, it is maximum with ore pulp contact area that charger and ore pulp contact area have also reached maximum, i.e. gas.
Stabilier 2 is fixed on the first disc for air inflation of adjustable inflatable component by support member, when adjustable inflatable component is in second or the third state, stabilier 2 rises the most therewith, now ore pulp needs more turbulent flow to make gas clash into mineral aggregate and combine, and the too early ore pulp entrance current stabilization region that makes is unfavorable for the combination of bubble and ore particle.
Adjustable inflatable component is in use adjusted by adjustable inflatable dish according to the real-time condition of ore pulp, particularly as follows:
1) after flotation starts, adjustable inflatable component supplies in the first state, foam recovery amount/concentrate the yield of flotation column overfall is measured by induction apparatus, if the yield in the unit interval is ascendant trend, the most adjustable inflatable component becomes the second state from the first state；
2) again through a unit interval, if yield is still ascendant trend, the most adjustable inflatable component becomes the third state from the second state；If yield maintains an equal level with the value recorded before, then keep the second state.
3) again through a unit interval, if yield is downward trend, then adjustable inflatable component is adjusted to low aeration quantity state from high aeration quantity, until reducing to the first state.
The trend of above-mentioned yield can have multiple formula or method to calculate, wherein conventional computational methods are to measure at the yield that two time end points of unit interval are corresponding and compare, if the yield of latter point is more than the yield of former point, then it it is ascendant trend；The yield of 2 is equal, should keep for aeration quantity；The yield of rear point is less than the yield of front point, then for downward trend.
Although the disclosed adjustable inflatable flotation column related to being particularly described with reference to embodiment; embodiments described above is illustrative and not restrictive; without departing from the present invention, all of change and modifications all within protection scope of the present invention.
