Description
Technical field
A kind of coal slime flotation device is the utility model is related to, it is especially a kind of to strengthen coarse slime flotation unit.
Background technology
With the continuous improvement of Mechanion degree, the fine particle content of feed coal is continuously increased, so as to cause product
Middle coal slurry content also sharply increases.However, in coal separation production, with the maximization of equipment, the upper size boundary of gravity treatment constantly carries
Height, causes its lower limit of separation also to improve many, the application and popularization of flotation column therewith
Also the upper limit of flotation is made reduce much, this allows for the presence of an effectively sorting granularity between gravity treatment and flotation
Notch, it is therefore, necessary to add coarse slime along with the phenomenon for causing coal slime race thick because live sieve aperture is worn can hardly be avoided
Sort link, by being recycled to this part coarse slime, thus avoid this part coal slime into
Enter floatation system interference flotation.Although existing shaking table, spiral separating, water-only cyclone etc. in separation of coarse slime equipment
Kinds of processes can be used for handling coarse slime, but or because effect is limited or because processing cost is higher, all fails to obtain gratifying
As a result.Relative to existing other separation of coarse slime equipment, hindered bed separator (the Teetered Bed introduced from foreign countries
Separator), TBS is referred to as, has been shown in separation of coarse slime relative to the certain excellent of other separation of coarse slime equipment
Gesture.But TBS assorting rooms must comply with non-homogeneous particle swarm suspension layering rule, be influenced by grain density, granularity and shape etc., point
When selecting the coarse slime of higher some adhesion degree, coal and the embedding cloth densification of mineral matter, often occur that sharpness of separation is poor, tail coal ash content is inclined
It is low, " race cleaned coal " phenomena such as.
Utility model content
The technical problem to be solved by the utility model is to overcome prior art defect, there is provided and it is a kind of simple in structure,
Production cost is low, and product structure is flexible, is conducive to the reinforcing coarse slime flotation unit of the efficient separation of Coarse Coal.
In order to solve the above-mentioned technical problem, the reinforcing coarse slime flotation unit of the utility model is collected including flotation concentrate
Groove, column body, lower prop, middling cycle system, base cone；The top of the column body is connected with flotation concentrate collecting tank, upper prop
The lower part of body is mutually passed through with water distributor, and water distributor is equipped with water distributing pore；The bottom of column body is connected with the top of lower prop；Under described
The top of cylinder is mutually passed through with pan feeding bend pipe, the bottom of lower prop be from top to bottom equipped with successively circulation ore pulp feeding pipe, cone tank and
Circulate ore pulp discharge nozzle；The middling cycle system is made of circulation ore slurry pump, pressure gauge and bubble generator；The circulation ore deposit
Slurry feeding pipe, circulation ore slurry pump, pressure gauge, bubble generator and circulation ore pulp discharge nozzle are sequentially connected by circulating ore pulp pipe；
The wide-mouth of the base cone is connected with lower prop bottom, and the slot of base cone is connected with debris tube.
As an improvement, the end of the water distributor is circular pipe, it is adapted with the inner wall of column body；The water distributing pore position
In the circular pipe top of water distributor.
The discharge port of the pan feeding bend pipe is vertically downward.
The beneficial effects of the utility model：1st, the decline manifold formed in the upper up-flow and lower prop formed in column body
Into two in cylinder to fluid, coal grain is carried by bubble and completes conveying of the mineralising in sinking into upper up-flow, coal grain
Enter flotation concentrate collecting tank under the action of upper up-flow, overcome difficulty of the Coarse Coal due to flotation effect difference easily caused by desorption
Topic, increases the yield of floatation clean coal；2nd, due to the presence of lower prop lower part middling cycle system, difficult float coal in cylinder is enhanced
The mineralization process of grain；3rd, due to pan feeding bend pipe discharge port vertically downward, reduce due to fluid in the lower prop that pan feeding is brought
Disturbance, enhance flotation mineralization process.

Embodiment
The embodiment of the utility model is further described below in conjunction with the accompanying drawings：
As shown in Figs. 1-2, the reinforcing coarse slime flotation unit of the utility model includes flotation concentrate collecting tank 1, column body
2nd, lower prop 4, middling cycle system, base cone 6；The top of the column body 2 is connected with flotation concentrate collecting tank 1, column body 2
Lower part is passed through with 3 phase of water distributor, and the end of water distributor 3 is circular pipe, is adapted with the inner wall of column body 2；Water distributor 3 is equipped with
Water distributing pore 15, water distributing pore 15 are located at 3 circular pipe top of water distributor；The bottom of column body 2 is connected with the top of lower prop 4；Institute
The top and 14 phase of pan feeding bend pipe for stating lower prop 4 are passed through, and the discharge port of pan feeding bend pipe 14 is vertically downward；The bottom of lower prop 4 is by upper
It is equipped with circulation ore pulp feeding pipe 13, cone tank 5 and circulation ore pulp discharge nozzle 8 successively under；The middling cycle system is by circulating
Ore slurry pump 11, pressure gauge 10 and bubble generator 9 form；The circulation ore pulp feeding pipe 13, circulation ore slurry pump 11, pressure gauge
