Description
Technical field
The utility model relates to ore dressing field, especially designs a kind of spiral microbubble floatation column.
Background technology
Along with the continuous intensification of the exploitation of coal resources degree of depth, coal reserves more and more lacks, and ature of coal worse and worse, causes slime content proportion in raw coal on average 20% ~ 30%, in order to meet the various index requests of user to coal, need to have come through effective washing.Current flotation is one of most effective method of process fine particle stage material, and flotation device and flotation column are main floatation equipments.But-0.074mm sized coal cement content is general all more than 60% in the floatation feed of most of coal preparation plant, this part coal slime floatability difference and in continuous worsening trend, and general flotation device and the separating effect of flotation column to the grey Bed for Fine Coal of height bad.
Utility model content
Task of the present utility model is for the bad problem of height grey Fine Coal Flotation effect, provides a kind of spiral microbubble floatation column.
In order to realize above-mentioned object, scheme of the present utility model is as follows:
A kind of spiral microbubble floatation column, comprise flotation column cylindrical shell (13), downflow weir (8), spray assemblies (9), rotating disk (5), motor (2), axle (4), Thysanophyllum (7) and air pump (6), it is characterized in that, described flotation column cylindrical shell (13) upper end 2/3 place is provided with feeding mouth (1), 4/5 place is provided with downflow weir (8), lower end is provided with underflow opening (11), the top of described downflow weir (8) is higher than the top of flotation column cylindrical shell (13), the top of described flotation column cylindrical shell (13) is provided with support (10), support (10) is provided with spray assemblies (9), there is motor (2) described flotation column bottom, the upper cover of the axle (4) be connected with motor (2) has rotating disk (5), the Thysanophyllum (7) fixing on the useful latch in the top (12) of axle (4), the bottom of described Thysanophyllum (7) is connected with air pump (6) with pipeline.
Micropore on described Thysanophyllum is lower close thin, and the bottom of Thysanophyllum is connected with air pump with pipeline, and compressed air is compressed into Thysanophyllum by air pump together with foaming agent, extrudes bubble by the micropore on Thysanophyllum.
Described Thysanophyllum is arranged on the flotation column center that the little ore particle of density is assembled.
Described downflow weir is provided with support, support is provided with spray assemblies.
The beneficial effect that the utility model produces is:
The utility model produces spiral vortex by rotating disk, utilizes the effect in the spiral flow field of force by heavy and light material separately, carries out first time and roughly select, utilize again foam to be flotated by the concentrate in light product, finally carry out secondary enrichment with water spray, complete foam selected.The utility model carries out sorting in conjunction with the effect in the spiral flow field of force and the double action of foam mineralising, and concentrate grade is high, optimizes the technique of ore dressing plant concentrate secondary flotation, simplifies flow process, and floating agent adopts General Medicine, has saved cost.The effect of the utility model due to the spiral flow field of force and the double action of foam mineralising, the efficiency of separation is high, effectively can shorten the height of flotation column.

Detailed description of the invention
Be easier to make feature of the present utility model understand and understand, elaborate below in conjunction with accompanying drawing.
The utility model comprises flotation column cylindrical shell (13), downflow weir (8), spray assemblies (9), rotating disk (5), motor (2), axle (4), Thysanophyllum (7) and air pump (6), described flotation column cylindrical shell (13) upper end 2/3 place is provided with feeding mouth (1), 4/5 place is provided with downflow weir (8), lower end is provided with underflow opening (11), the top of described downflow weir (8) is higher than the top of flotation column cylindrical shell (13), the top of described flotation column cylindrical shell (13) is provided with support (10), support (10) is provided with spray assemblies (9), there is motor (2) described flotation column bottom, the upper cover of the axle (4) be connected with motor (2) has rotating disk (5), the Thysanophyllum (7) fixing on the useful latch in the top (12) of axle (4), be connected with air pump (6) at the bottom of described Thysanophyllum (7) pipeline.
When using the utility model, first motor and air pump is opened, after the ore pulp crossed through chemicals treatment injects from feeding mouth (1) tangent line, under the effect of rotating disk (5), ore pulp forms spiral vortex, the particle that density is large gets rid of at edge under the effect in the spiral flow field of force, flow out along barrel from underflow opening (11), obtain tail coal, the little movement of particles of density is to flotation column center, compressed air and foaming agent are pressed into Thysanophyllum (7) and form bubble afterwards and pile up center, ore particle and the bubble of staying center meet, the ore particle that hydrophobicity is good sticks on bubble, follow bubble and rise to downflow weir (8), through the water spray of spray assemblies (9), mineral laden bubble is cleaned, remove the high ash particle carried secretly, remaining foam flows out from downflow weir (8), obtain high-grade cleaned coal.
Above-described embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
