Description
Technical field
It is especially a kind of to strengthen coarse slime flotation unit the present invention relates to coal slime flotation device.
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, its lower limit of separation is caused also to improve therewith many, the application and popularization of flotation column also make the upper limit of flotation reduce much, this
Allow for existing between gravity treatment and flotation an effectively sorting granularity breach, along with causing coal slime because live sieve aperture wears
Thick phenomenon is run to can hardly be avoided, it is therefore, necessary to set up separation of coarse slime link, by being returned to this part coarse slime
Receive, so as to avoid this part coal slime from entering floatation system interference flotation.Although existing shaking table, spiral point in separation of coarse slime equipment
The kinds of processes such as choosing, water-only cyclone can be used for handling coarse slime, but or because effect is limited or because processing cost is higher, all fails
Obtain gratifying result.Relative to existing other separation of coarse slime equipment, the hindered bed separator introduced from foreign countries (
Teetered Bed Separator), referred to as TBS, shown in separation of coarse slime relative to other separation of coarse slime
The some superiority of equipment.But TBS assorting rooms must comply with non-homogeneous particle swarm and suspend layering rule, by grain density, granularity and
Shape etc. influences, and when sorting the coarse slime of higher some adhesion degree, coal and the embedding cloth densification of mineral matter, sharpness of separation often occurs
Phenomena such as difference, tail coal ash content are relatively low, " race cleaned coal ".
The content of the invention
The technical problems to be solved by the invention are to overcome prior art defect, there is provided a kind of simple in construction, production
Cost is low, and product structure is flexible, is advantageous to the reinforcing coarse slime flotation unit of the efficient separation of Coarse Coal.
In order to solve the above-mentioned technical problem, reinforcing coarse slime flotation unit of the invention include flotation concentrate collecting tank, on
Cylinder, lower prop, middling cycle system, base cone, water distributor and pan feeding bend pipe；Collected with flotation concentrate on the top of the column body
Groove is connected, and the bottom of column body is mutually passed through with water distributor, and water distributor is provided with water distributing pore；The bottom of column body and the top of lower prop
It is connected；The top of the lower prop is mutually passed through with pan feeding bend pipe, and the bottom of lower prop is from top to bottom sequentially provided with circulation ore pulp pan feeding
Pipe, cone tank and circulation ore pulp discharge nozzle；The middling cycle system is by circulation ore slurry pump, pressure gauge and bubble generator group
Into；The circulation ore pulp feeding pipe, circulation ore slurry pump, pressure gauge, bubble generator and circulation ore pulp discharge nozzle are by circulating ore deposit
Slurry pipe is sequentially connected；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 circle, it is adapted with the inwall of column body；The water distributing pore is located at cloth
The end upper of water pipe.
The discharging opening of the pan feeding bend pipe is vertically downward.
Beneficial effects of the present invention：1st, the sinking formed in the upper up-flow and lower prop formed in column body forms post
Internal two carry coal grain by bubble and complete conveying of the mineralising in sinking into upper up-flow, coal grain is upper to fluid
Enter flotation concentrate collecting tank in the presence of up-flow, overcome problem of the Coarse Coal due to flotation effect difference easily caused by desorption,
Increase the yield of floatation clean coal；2nd, due to the presence of lower prop bottom middling cycle system, difficult float coal grain in cylinder is enhanced
Mineralization process；3rd, due to pan feeding bend pipe discharging opening vertically downward, reduce due to fluid in the lower prop that pan feeding is brought
Disturbance, enhances flotation mineralization process.

Embodiment
Embodiments of the invention are further described below in conjunction with the accompanying drawings：
As shown in Figure 1-2, reinforcing coarse slime flotation unit of the invention includes flotation concentrate collecting tank 1, column body 2, lower prop
4th, middling cycle system, base cone 6, water distributor 3 and pan feeding bend pipe 14；The top of the column body 2 and the phase of flotation concentrate collecting tank 1
Even, bottom and the phase of water distributor 3 of column body 2 are passed through, and the end of water distributor 3 is circle, is adapted with the inwall of column body 2；Water distribution
Pipe 3 is provided with water distributing pore 15, and water distributing pore 15 is located at the end upper of water distributor 3；The bottom of column body 2 and the top phase of lower prop 4
Even；The top of the lower prop 4 is passed through with the phase of pan feeding bend pipe 14, and the discharging opening of pan feeding bend pipe 14 is vertically downward；The bottom of lower prop 4
From top to bottom it is sequentially provided with circulation ore pulp feeding pipe 13, cone tank 5 and circulation ore pulp discharge nozzle 8；The middling cycle system by
Circulation 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
Table 10, bubble generator 9 and circulation ore pulp discharge nozzle 8 are sequentially connected by circulating ore pulp pipe 12；The wide-mouth of the base cone 6 is with
The bottom of cylinder 4 is connected, and the slot of base cone 6 is connected with debris tube 7.
The course of work of the present invention：Entered after a certain amount of Coarse Coal is sized mixing by pan feeding bend pipe 14 in lower prop 4 downwards
Motion, form sinking.As bubble generator 9 using circulate ore slurry pump 11 suck air caused by bubble enter lower prop 4 in
Floating, both ore pulp and bubble for settling downwards move toward one another is ramped up, adverse current collision mineralising, adverse current ore deposit are carried out in lower prop 4
Change bubble to move upwards, the difficult float coal grain in part is desorbed during bubble rises with bubble, and desorption coal grain sinks to entering
Turbulent mineralising is carried out to middling cycle system.Adverse current mineral laden bubble and turbulent mineral laden bubble move upward to the top of water distributor 3
In ascending current, because the flow velocity of upper up-flow is more than the maximum settlement end speed of Coarse Coal particle swarm, now mineral laden bubble carries easy
The difficult float coal grain of float coal grain and mineral laden bubble desorption enters flotation concentrate collecting tank 1 in the presence of ascending current.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, some improvement can also be made under the premise without departing from the principles of the invention, and these improvement also should be regarded as the present invention's
Protection domain.
