Abstract
The invention relates to a feeding device of an inflatable flotation column, belongs to the field of flotation separation equipment and is particularly applicable to clean flotation and refinement of particles in fine flake graphite production. The feeding device of the inflatable floatation column consists of an upper column body, a feed chute, a diverting chute, an outer chute, an inner chute and sieve plates. The feed chute is arranged on the outer side of the upper column body, two ends of the diverting chute are respectively connected with the feed chute and the outer chute, the outer chute is arranged on the outer side of the upper column body, and the inner chute and the sieve plates are arranged on the inner side of the upper column body. The outer chute is a circular groove which is arranged, along the angle of alpha, on the outer side of the position at 1/2 height of the upper column body. The inner chute is a circular groove which is arranged, along the angle of alpha, on the inner side of the position at 1/2 height of the upper column body. The feeding device has the advantages that good crude mineralization effect, feeding stability and uniform feed distribution and good flotation effect are achieved.
Description
Affiliated technical field
The present invention relates to a kind of feeding device of pneumo type flotation post, be particularly useful for fine cleaner flotation in thin crystalline flake graphite production and purify, belong to floatation equipment field.
Background technology
Pneumo type flotation post is widely used in fine cleaner flotation in the nonferrous productions such as copper, tungsten, molybdenum and purifies, improve grade and the rate of recovery of non-ferro metals floatation concentrate, the feeding device of this pneumo type flotation post adopts multiple spot taper ore pulp charging gear, has the following disadvantages: 1) raw ore and medicament mineralising weak effect; 2) pan feeding is unstable, and pan feeding kinetic energy is large, and disorderly phenomenon is serious, and part bubble easily breaks; 3) pan feeding maldistribution, flotation effect is poor.
The pneumo type flotation post of domestic this feeding device is seldom applied in fine cleaner flotation purification in thin crystalline flake graphite production at present.
Therefore, design a kind of feeding device of pneumo type flotation post, be particularly useful for fine cleaner flotation in thin crystalline flake graphite production and purify, further improve grade and the rate of recovery of graphite flotation concentrate.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, the feeding device of the pneumo type flotation post of the stable and pan feeding distributed uniform of a kind of pan feeding is provided.
The feeding device of a kind of pneumo type flotation post of the present invention, is made up of upper cylinder, feed chute, splitter box, outer side slot, inner side slot, sieve plate; Feed chute is arranged in the external side of upper prop, and splitter box two ends are connected with feed chute, outer side slot respectively, and outer side slot is arranged in the external side of upper prop, and inner side slot and sieve plate are arranged in cylinder inner side.
Described feed chute is to be provided with semi-circular groove in the cylinder outside at upper height of column 1/2 place, is divided into 4～6 parts, feeding pipe of at right angle setting in the middle part of semi-circular groove with dividing plate with holes.Its Main Function is to extend the sorted materials mineralising time, and pan feeding is tended towards stability, and has improved flotation effect.
Described splitter box is to be arranged in bottom, feed chute two ends, and is connected with outer side slot.Its Main Function is material to be divided into two parts enter outer side slot, reduces pan feeding kinetic energy.
Described outer side slot is the circular trough of arranging along α angle in the cylinder outside at upper height of column 1/2 place, is divided into 8～10 parts with dividing plate with holes, is uniformly distributed four holes with outer side slot on the upper column side wall being connected.Its Main Function is further to extend the sorted materials mineralising time, and pan feeding is tended towards stability, and has improved flotation effect.
Described inner side slot is the circular trough of arranging along α angle in the cylinder inner side at upper height of column 1/2 place, is divided into 10～12 parts with dividing plate with holes, and the inner side of inner side slot is evenly provided with eight rectangle discharging openings, is staggeredly arranged up and down.Its Main Function is to extend the sorted materials mineralising time, reduce pan feeding kinetic energy into～step, and sorted materials is evenly distributed on pole section, fully with the bubble adverse current collision of rising, has improved the rate of recovery of flotation concentrate.
Described sieve plate is arranged on cylinder inner side, and the bottom of inner side slot, is evenly arranged a lot of holes on sieve plate.Its Main Function: be to make the bubble distribution of rising even on the one hand, and destroy the larger bubble rising, improved the grade of flotation concentrate; That inner side slot is distributed on pole section and can not be dropped to sieve plate by the ore pulp of flotation on the other hand, be uniformly distributed by sieve plate, with the bubble adverse current collision of rising, some material sticks to bubble floating and goes out and reclaim, and has further improved the flotation concentrate rate of recovery simultaneously.
The invention has the beneficial effects as follows: raw ore mineralising is effective, pan feeding is stablized and pan feeding distributed uniform, and flotation effect is good, is particularly useful for fine cleaner flotation in thin crystalline flake graphite production and purifies.
The contrast of flotation concentrate quality index:
Certain thin crystalline flake graphite ore deposit, raw ore average grade 9.3%.Employing mineral processing circuit is: raw ore → coarse crushing → in small, broken bits → corase grind → roughly selecting, scan for twice → rough concentrate regrind for nine times, ten times thick selected → filtration → oven dry → classification → packing, the floatation equipment using is air agitation type floatation device, final Floatation Concentrate Grade 93.5%, the concentrate rate of recovery 85.1%.
Former mineral processing circuit is improved to: raw ore → coarse crushing → in small, broken bits → corase grind → roughly selecting, scan for twice → rough is regrinded for seven times, twice selected once purging selection → filtration → oven dry → classification → packing of eight roughly select → concentrate, roughly selecting the floatation equipment that operation selects is air agitation type floatation device, the equipment that selected operation is selected is the pneumo type flotation post of this feeding device of configuration, final Floatation Concentrate Grade 96. youngster %, the concentrate rate of recovery 89.68%.
Accompanying drawing explanation
