Abstract

The utility model discloses a coal slime water rectification desliming equipment, including pan feeding pipe, pan feeding cloth plate, pipe rectification district, overflow pipe, underflow pipe. Its characterized in that, cell body one side has set up the pan feeding distributing box, and the ore pulp is managed for income by the pan feeding, evenly gives the sloughing -off tank through pan feeding cloth plate to lower part in the edge sloughing -off tank side entering trough forms the ore pulp stream that rises in the cell body. The ore pulp rises in rectification district, and the velocity of flow reduces gradually, and the high density coarse grain that sedimentation rate is greater than the ascending velocity of flow sinks to the cell body bottom, disturbs the little thin granule of low -density of sedimentation rate velocity of flow after rectification district's rectification further to reduce, mixes simultaneously during partial low -density large granule in the upwelling also sinks to the underflow, becomes the underflow product, and the upwelling that passes the rectifying tube gets into the overflow launder along the sloughing -off tank side, discharges through the overflow pipe, becomes the overflow product. The underflow flow can be adjusted through the valve to adjust the ore pulp speed (overflow flow) that rises, guarantee the cut size of equipment, reinforcing desliming effect.

Description

A kind of black water rectification desliming device
Technical field
This utility model relates to a kind of black water rectification desliming device, belongs to Mineral Processing Engineering field.
Background technology
Along with the intensification of coal mining mechanization degree and increasing year by year of coal mining amount, in raw coal, particulate and superfine granule content are more and more higher.The wide popularization and application of major diameter dense medium cyclone simultaneously, lower limit of separation improves, this drawback is made to highlight further, reduce discharging under policy implication at national energy-saving, the quality of coal product is proposed higher requirement by consumption market, therefore the sorting strengthening Bed for Fine Coal becomes the difficulties of Coal dressing washing industry, also becomes the focus that coal separation worker in countries in the world inquires into and studies.The effect of duff sorting is closely bound up with particulate coal grading and desliming technology.The major way of Fine grain content is flotation, and along with the raising of Coal Mechanical degree, the thin cement content of high ash is more and more higher, not only results in floatation clean coal ash higher, and increases reagent consumption.If floatation feed is carried out desliming process, not only reduce floatation feed amount, it is ensured that floatation clean coal ash, and reduce reagent consumption, save production cost.The technological development of de slime flotation is relatively slower, and it it is critical only that and lacks the front desliming device of efficient choosing.Therefore, the efficient graded desliming equipment of development of new is the key of breakthrough bottleneck.
Summary of the invention
The purpose of this utility model is to provide a kind of black water rectification desliming device, and simple to operate, desliming efficiency is high.
For reaching above-mentioned purpose, the technical scheme that this utility model provides is: a kind of black water rectification desliming device.Including feeding pipe, pan feeding drapery panel, pipe commutating zone, overflow pipe, underflow pipe.
Cell body side is provided with pan feeding distributing trough, and ore pulp is fed by feeding pipe, uniformly feeds sloughing-off tank through pan feeding drapery panel, and enters trough middle and lower part along sloughing-off tank side, forms rising flow of slurry in cell body.Ore pulp rises in sloughing-off tank, flow velocity is gradually lowered, sedimentation velocity sinks to bottom cell body more than the high density coarse granule of upflow velocity, low-density fine grained flow velocity after commutating zone rectification that hindered falling speed is little reduces further, the part low-density bulky grain being simultaneously mixed in upwelling also sinks in underflow, becomes underflow product, and enters overflow launder through the upwelling of rectifier tube along sloughing-off tank side, discharge through overflow pipe, become overflow product.Underflow flow can be adjusted by valve, thus regulating rising ore pulp speed (excess flow), it is ensured that the partition size of equipment.
The utility model has the advantages that: simple structure is reasonable, easy to adjust;Owing to adding commutating zone, reducing mispairing amount, thus improve classification efficiency, enhancing desliming effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of pan feeding drapery panel;
Fig. 3 is the schematic diagram of pipe commutating zone.
Drawing illustrates: (1) feeding pipe;(2) pan feeding drapery panel;(3) pipe commutating zone;(4) overflow pipe;(5) underflow pipe.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model being described in further detail, the description of this part is only exemplary and explanatory, and protection domain of the present utility model should not have any restriction effect.
Referring to accompanying drawing, this utility model includes feeding pipe (1), pan feeding drapery panel (2), pipe commutating zone (3), overflow pipe (4), underflow pipe (5).Cell body side is provided with pan feeding distributing trough, and ore pulp is fed by feeding pipe (1), uniformly feeds sloughing-off tank through pan feeding drapery panel (2), and drapery panel (2) has been evenly arranged the aperture that diameter is 20mm.Pan feeding ore pulp feeds in feed chute through feeding pipe (1), ore pulp is covered with the whole cross section of feed chute, rise from the hole drapery panel equably after eliminating eddy current in feed chute, feed in sloughing-off tank in " waterfall " shape overflow again, such ore pulp feeds sloughing-off tank along whole uniform groove width, it is ensured that have a uniform rising flow of slurry on the whole horizontal section of sloughing-off tank.Ore pulp rises in sloughing-off tank, flow velocity is gradually lowered, sedimentation velocity sinks to bottom cell body more than the high density coarse granule of upflow velocity, low-density fine grained flow velocity after commutating zone rectification that hindered falling speed is little reduces further, and the part low-density bulky grain being simultaneously mixed in upwelling also sinks in underflow, through underflow pipe (5), become underflow product, and enter overflow launder (4) through the upwelling of rectifier tube along sloughing-off tank side, discharge through overflow pipe (4), become overflow product.Underflow flow can be adjusted by valve, thus regulating rising ore pulp speed (excess flow), it is ensured that the partition size of equipment.
The above, be only preferred embodiment of the present utility model, and this utility model not does any pro forma restriction.Any those skilled in the art, according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all still fall within the scope of this utility model technical protection scheme.
