Abstract
The invention discloses an adjustable inflatable flotation column, which comprises an adjustable air inflation assembly. At least three air inflation discs are utilized for the adjustable air inflation assembly, and therefore, the adjustable air inflation assembly has at least three air inflation states; in different air inflation states, not only does an air supply amount change, but also a contact area of the air inflation assembly with ore pulp changes accordingly, thereby leading to fast response of the air inflation capability according to a composition level of the ore pulp. A flow stabilizing plate is fixed on the first air inflation disc of the adjustable air inflation assembly by means of a supporting piece; the height of the flow stabilizing plate changes along with the height change of the adjustable air inflation assembly, thereby leaving more sufficient time for ore particles bonding with air bubbles.
Description
The present invention is the divisional application of patent of invention " a kind of adjustable inflatable flotation column ", and the applying date of original application is on May 15th, 2014, and the application number of original application is 2014102046828, and the invention and created name of original application is " a kind of adjustable inflatable flotation column ".
Technical field

Detailed description of the invention
It is 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, ore pulp after inflating mineralising in advance is squeezed in flotation column main body by feeding mouth, 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 for 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 to cause lacks first filling channel 10, 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 to continue to rise after rising to predetermined altitude, and the second disc for air inflation has and causes few second filling channel 10；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 can not continue to lift up 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 and causes few 3rd filling channel 11.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 three disc for air inflations diameter not etc., in general X, Y, Z tri-value is unequal, it is preferred to 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 is set in the first disc for air inflation and supplies only by 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 also increases therewith, and this makes within the shorter time, more effective change air-fill levels.
As shown in Figure 5, adjustable inflatable component is when the third state, first disc for air inflation drives the second disc for air inflation to lift up, 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, charger and ore pulp contact area have also reached maximum, and namely gas is maximum with ore pulp contact area.
Stabilier 2 is fixed on the first disc for air inflation of adjustable inflatable component by support member, when being in second or the third state when adjustable inflatable component, stabilier 2 also rises 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, induction apparatus foam recovery amount/concentrate yield measurement to flotation column overfall, if the yield in the unit interval is ascendant trend, then adjustable inflatable component becomes the second state from the first state；
2) then through a unit interval, if yield is still ascendant trend, then 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) then through a unit interval, if yield is downward trend, then adjustable inflatable component is adjusted from high aeration quantity to low aeration quantity state, 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 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.
