Description
Art
The utility model relates to a kind of major diameter floatation column feeding device, belongs to flotation technology field.
Background technology
The floatation column feeding device technology relative maturity used at present, is applied in column diameter and is less than on the flotation column of φ 5000mm, and effect is better, but is applied in column diameter and is more than or equal on the flotation column of φ 5000mm, has the following disadvantages:
1, outside feed chute deposition material, blocking isocon;
2, in the middle part of cylinder, material is few, and pole section material maldistribution, the flotation concentrate rate of recovery is low, flotation effect is poor.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of pan feeding distributed uniform and the major diameter floatation column feeding device of the raising flotation concentrate rate of recovery.
A kind of major diameter floatation column feeding device described in the utility model, is provided with ore pulp preprocessor, blender, outside isocon, inner side isocon, cylinder, outside feed chute, inner side splitter box, middle distributing trough; The feeding end of blender is connected with ore pulp preprocessor, the discharge end of blender is connected with outside isocon and inner side isocon, outside isocon is connected with outside feed chute, outside feed chute is arranged in outside cylinder, inner side feed chute is arranged in inside cylinder, and middle distributing trough is connected with inner side splitter box.
Described blender is provided with feeding pipe, tapered amplifier, overflow launder, uniform distribution plate, storage box.The Main Function of described blender: the mixture of selected ore pulp, floating agent, air flow to overflow launder certainly by tapered amplifier, certainly storage box is flow to uniformly by the ease stream weir of overflow ladle, again by uniform distribution plate alter direction, make ore pulp distribution area expand simultaneously, improve raw ore remineralization efficacy, ore pulp is tended towards stability, and by external shunt pipe from flowing to outside flotation column in feed chute, by internal shunt pipe from flowing in cylinder on cross section.
Described inner side isocon is provided with feeding pipe, tapered amplifier, shunt umbrella, shunt umbrella is evenly arranged several aperture.The Main Function of described inner side isocon: combine with inner side splitter box, middle distributing trough, is evenly distributed on flotation pulp on pole section, improves the flotation concentrate rate of recovery.
Described outside feed chute is arranged with feed chute outside cylinder, is divided into a few part with closure plate, and the outer middle side part of every part feed chute is provided with a feeding mouth, and its columnae medialis body sidewall is provided with several discharging opening.Its Main Function extends the selected ore pulp mineralising time, pan feeding tended towards stability, improves flotation effect.
Described inner side splitter box is provided with splitter box inside cylinder, is divided into a few part with closure plate, and the lower inside of every sections inner side splitter box is arranged with rectangle discharging opening, and the inside upper part of every sections inner side splitter box is provided with a semicircular outlet.Its Main Function extends selected ore pulp mineralising time, reduction pan feeding kinetic energy further, selected ore pulp branched in cylinder equably, improves the flotation concentrate rate of recovery.
Described middle distributing trough, is provided with a semi-circular groove, and it arranges several hole, and its downflow weir has several " V " shape opening.Described middle distributing trough is connected with the inside upper part semicircular outlet of inner side splitter box, its Main Function is that selected ore pulp is delivered to cylinder central authorities uniformly, be evenly distributed on pole section by the downflow weir of " V " shape opening and several hole, further increase the flotation concentrate rate of recovery.
The beneficial effects of the utility model are: raw ore remineralization efficacy is good, and pan feeding is stablized and pan feeding distributed uniform, and the flotation concentrate rate of recovery is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
In figure: 1-ore pulp preprocessor, 2-blender, isocon outside 3-, isocon inside 4-, 5-cylinder, feed chute outside 6-, splitter box inside 7-, distributing trough in the middle of 8-.
Detailed description of the invention
As shown in Figure 1: selected pulp conveying is in ore pulp preprocessor 1, mix further through blender 2 with floating agent, wherein a part is through outside isocon 3 feed chute 6 outside flowing to respectively, by several discharging opening on inner side cylinder 5 sidewall of outside feed chute 6, from flowing to inner side splitter box 7, middle distributing trough 8 is connected with inner side splitter box 7, ore pulp to be evenly arranged in cylinder on whole cross section by distributing trough 8 in the middle of the several rectangle discharging opening of the bottom inside inner side splitter box 7 and top, ore pulp to be arranged in the middle part of cylinder on cross section through the shunt umbrella of inner side isocon 4 by a part uniformly in addition, mineralising is collided with the abundant adverse current of bubble risen.
