Abstract
The utility model relates to a two side overflow floating foam collecting tank which is matched with a flotation column. The utility model comprises a boat-shaped collecting tank. The upper part of the collecting tank is opened and forms an inner overflow weir and an outer overflow weir. The lower part of the outer side of the collecting tank is provided with a plurality of foam outlet ports. In addition, both the inner side and the outer side of the middle part of the collecting tank are provided with a skeleton which is used for supporting whole construction members, and a sieve. The foam collecting tank is arranged in the flotation column and enables foam to overflow through the inner side and the outer side. Therefore, the overflow weir of foam increases by one time, the discharging speed of foam is accelerated, and foam dead area and collapse are reduced. The utility model controls the thickness of a foam layer by using self flotation and creates conditions for liquid level detection and control in the flotation column.
Description
The utility model relates to a kind of foam gathering-device that is used for flotation column (machine), the floated foam feeder of a kind of two-sided overflow of more specifically saying so.
At present, the foam feeder that is used for flotation device (post) is the outer single face overflow launder that hangs of cell body; KHD company flotation column has also adopted the fixing formula foam feeder that overflows that is positioned at froth bed central authorities; In addition, in order to regulate the foam spill-out, the XPM air jet flotation machine is provided with movable soft board to regulate height of weir plate on the foam tank downflow weir.Along with the progress of equipment enlarging, floatation equipment inner foam aspect is long-pending more and more big, in order in time promptly to discharge foam, relies on traditional single face overflow foam feeder to be far from suitable merely.Particularly for thicker froth bed in the flotation column, untimely discharge foam just easily causes foam dead band or froth bed mummification even landslide, influences the performance of device efficiency.In addition, because foam bed thickness and thickness fluctuation are big, the foam speed that scrapes also is very difficult to regulate (become flotation column in a way and realized the obstacle of control automatically).Single face suspension type foam feeder is the needs of incompatibility flotation technology development.
The purpose of this utility model provides a kind ofly can discharge foam fast in time, can adapt to the froth bed varied in thickness again, and simple in structure, is easy to install the floated foam feeder of two-sided overflow of adjusting.
The purpose of this utility model can realize in the following manner: the floated foam feeder of a kind of two-sided overflow, include feeder, described feeder is annular (also can be designed to other a shape as required) member, its cross section is one " ship " shape, open ports is arranged at top, form inside and outside two foam downflow weirs, have some foam outlets, be used to connect discharge-channel in the feeder outer lower portion.The inside and outside both sides at feeder middle part are provided with skeleton, lay screen cloth on the skeleton, and they are respectively applied for supports whole member and froth bed.For large-scale foam tank, also can at other position of feeder supporting member be set as required.
The utility model compared with prior art has following effect:
1. because the foam feeder is arranged on the inside of flotation cylinder, make the foam can be, thereby make the foam downflow weir extend nearly one times by the overflow of inside and outside both sides, accelerated the foam velocity of discharge, interior dead band and the landslide of minimizing froth bed;
2. save mechanical float skimming device, reduce equipment manufacturing cost;
3. rely on the control froth bed thickness that self suspends, help liquid level Detection ﹠ Controling in the flotation column;
4. simplified device structure, made equipment have stronger globality.
Description of drawings:
Accompanying drawing is a structural front view of the present utility model.
The utility model is described in further detail with reference to the accompanying drawings:
Shown in accompanying drawing: the floated foam feeder of a kind of two-sided overflow, include feeder 1, described feeder 1 is one " ship " tee section member, open ports is arranged at top, the bottom sealing.The upper opening of feeder 1 forms inside and outside two foam downflow weirs.Have the foam outlet 2 of some in feeder 1 outer lower portion, quantity can be determined according to feeder 1 size and foam discharge rate.Inside and outside both sides, the middle part of feeder 1 are provided with skeleton 5 and screen cloth 3,4.By selection, can be suspended in the assigned address in the flotation column to guarantee feeder 1 to skeleton 5 and screen cloth 3,4 weight.
Install and the course of work: foam feeder 1 is placed the top of cylinder, with flexible pipe the foam outlet 2 on the feeder 1 is linked to each other with flotation column then.Select by weight, guarantee that whole cell body is suspended to the formulation position when the flotation column operate as normal skeleton 5 and screen cloth 3,4.Like this, can guarantee that foam enters in the feeder 1 through the two-sided overflow of the upper opening of feeder 1, discharge through outlet 2 then.
Claims (3)
1. floated foam feeder of two-sided overflow, include feeder (1), its special position is: described feeder (1) is the member of " ship " tee section, and opening is arranged at top, form inside and outside two foam downflow weirs, have some foam outlets (2) in feeder (1) outer lower portion.
2. the floated foam feeder of two-sided overflow according to claim 1 is characterized in that: the inside and outside both sides at feeder (1) middle part are provided with the skeleton (5) that is used to support whole member and froth bed and screen cloth (3), (4).
3. the floated foam feeder of two-sided overflow according to claim 2 is characterized in that: by regulating the weight of skeleton (5) and screen cloth (3), (4), so that foam feeder (1) is suspended to assigned address.
