Abstract
The utility model relates to an inflating device for an inflatable flotation column and belongs to the field of flotation devices. The inflating device for the inflatable flotation column is particularly suitable for fine floatation and refinement of fine particles generated during crystalline flake graphite production. The inflating device for the inflatable flotation column is composed of an air storage device (I), a sieve plate (I), foaming guns, an air storage device (II), a sieve plate (II) and an air storage device (III), wherein the air storage device (I), the air storage device (II), the air storage device (III) and the foaming guns are all arranged outside a lower column body, the sieve plate (I) and the sieve plate (II) are arranged inside the lower column body and located above the foaming guns, the foaming guns are arranged outside the lower column body and are distributed on three layers with the lead angle of alpha, the lead angle of beta and the lead angle of gamma respectively, and according to the installation angle of each foaming gun, the angel of elevation is eta, and each foaming gun is inserted into the lower column body in the mode that the included angle between the foaming gun and the axis is theta. The inflating device for the inflatable flotation column has the advantages that bubbles are evenly distributed, breakage, caused by collision, of the bubbles is avoided, the probability that the bubbles collide with ore pulp particles is increased, and the grade and the recovery rate of flotation concentrate are high.
Description
Affiliated technical field
The utility model relates to a kind of aerating device of pneumo type flotation post, is particularly useful for fine cleaner flotation in thin crystalline flake graphite production and purifies, and belongs 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 aerating device of this pneumo type flotation post is comprised of air feed system and foam gun, in lower prop outside vertical, in lower prop level, is evenly arranged one deck foam gun.Have the following disadvantages: 1) bubble distribution is inhomogeneous, cylinder middle part bubble is many, and sidewall bubble is few; 2) foam gun is facing to foaming, and cylinder middle part part bubble hit breaks, and flotation effect is poor; 3) only arrange one deck foam gun, the flotation concentrate rate of recovery is low.
The pneumo type flotation post of domestic this aerating device is seldom applied in fine cleaner flotation purification in thin crystalline flake graphite production at present.
Therefore, design a kind of aerating 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 purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of bubble distribution evenly and the aerating device of the pneumo type flotation post of three layers of layout of foam gun.
The aerating device of a kind of pneumo type flotation post described in the utility model, is comprised of caisson (I), sieve plate (I), foam gun, caisson (II), sieve plate (II), caisson (III); Caisson (I), caisson (II), caisson (III) and foam gun are arranged in lower prop outside; Sieve plate (I), sieve plate (II) are arranged in the top of foam gun inside lower prop.
Caisson (I), caisson (II), caisson (III) are comprised of cylinder, air inlet pipe, Pressure gauge, escape pipe respectively.
Foam gun is arranged in lower prop outside, and presses respectively α, β, three layers of distribution of γ lead angle, and its setting angle is: vertical angle η, and enter lower prop with axis angle θ oblique cutting.Its Main Function is: bubble distribution is even, and has avoided bubble hit to break; Bubble forms the eddy flow field of force, and spiral, has extended bubble and ore pulp particle collision opportunity, and flotation effect is good; Arrange three layers of foam gun, realized selected, roughly select, scan three phases, improved the flotation concentrate rate of recovery.
Described sieve plate (I), sieve plate (II), be evenly arranged a lot of holes on it.Its Main Function: make on the one hand the bubble distribution of rising even, and destroy the larger bubble rising, improved the grade of flotation concentrate; Can not be dropped to sieve plate (I), sieve plate (II) by the ore pulp of flotation on the other hand, by sieve plate, be uniformly distributed, with the bubble adverse current collision of rising, some material sticks to bubble floating and goes out and reclaim, and further improves the concentrate rate of recovery simultaneously.
The beneficial effects of the utility model are: bubble distribution is even, and have avoided bubble hit to break, and have extended bubble and ore pulp particle collision opportunity, and Floatation Concentrate Grade and the rate of recovery are high, are particularly useful for fine cleaner flotation in thin crystalline flake graphite production and purify.
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 aerating device of configuration, final Floatation Concentrate Grade 96.11%, the concentrate rate of recovery 89.68%.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation,
Fig. 2 is A-A cutaway view in Fig. 1,
In figure: 1-caisson (I), 2-sieve plate (I), 3-foam gun, 4-caisson (II), 5-sieve plate (II),
