Description
Technical field
The utility model relates to a kind of sorting unit, is specifically related to a kind of eddy flow and scans interference bed sorting unit.
Background technology
At present, the separation of coarse slime equipment that domestic and international industrial applications is more mainly contains: hydrocyclone, Slime dense medium cyclone, spiral, liquid-solid fluid bed separation machine etc.Spiral, grading principle is the difference stressed on spiral groove face of different densities particle and produces the difference of its motion component velocity, is finally presented as that the distribution along spiral groove face radial direction is different, thus makes the particle of different densities complete sorting.Have good separating effect for easy coal separation, but fuselage height is large, during coal varitation, technological parameter not easily regulates, and when separating density is lower, separating effect is poor.It is higher to fluctuate bad adaptability, separating density of pan feeding, restricts the key that it applies in separation of coarse slime; The density of the heavy suspension of Slime dense medium cyclone is close to separating density, and thus sharpness of separation is high.Its shortcoming is the impact that separating effect is subject to the factor such as granularity and Algorithm of Density Control of coal slime medium solid.
Liquid-solid fluid bed coarse slime size machine is as a kind of novel separation of coarse slime equipment based on sedimentation theory, have that separating density is low, equipment is simple, automatically control and the advantage such as processing ease, in recent years, be widely applied in coal preparation plant of China, also become the study hotspot of domestic and international coal separation industry.But, along with coal preparation plant's feed coal ature of coal goes from bad to worse and more strict to separating effect requirement of user, two traditional product liquid-solid fluid bed coarse slime size machines expose some problems in actual applications gradually: the thin sludge-polluted head coal product of (1) high ash.In ature of coal when more crisp and easy argillization, in the thick cleaned coal after fluid bed separation, the thin cement content of high ash is higher, increases cleans ash.(2) difficulty that intermediate density content is higher selects separation of coarse slime effect poor.The major part difficult choosing of coal preparation plant's coarse slime itself or extremely difficult choosing, the thick cleans ash of liquid-solid fluid bed overflow is higher, and underflow ash content is on the low side, and sorting progress is poor.(3) effectively sorting particle size range is too narrow, is difficult to expand.
Especially to the sorting of coarse slime in 2-0.25mm particle size range, be the weak link of existing coal preparation technique.Lack the development equipment of this particle size range height sharpness of separation seriously being constrained to coal preparation technique, become the bottleneck problem that coal preparation plant ensures product quality, increases economic efficiency gradually.Only have the effective sorting problem solving coarse slime processing links, the pollution to cleaned coal could be reduced, ensure the maximization of wholegrain level quality of cleaned coal and productive rate.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of eddy flow to scan interference bed sorting unit, and high density coarse slime effectively can carry out sorting, and separator still can obtain good separating effect when pan feeding washability is poor.
To achieve these goals, the technical solution adopted in the utility model is: a kind of eddy flow scans interference bed sorting unit, comprise point selections and the eddy flow section of scanning, sorting section is positioned at the top of the eddy flow section of scanning, divide selections and the eddy flow section of scanning composition interference column body, divide selections top to be provided with downflow weir and feeding mouth, feeding mouth is inserted into sorting intersegmental part from downflow weir top; The eddy flow section of scanning is respectively equipped with water inlet, underflow opening, water inlet axis and the eddy flow section of scanning cylinder tangent, underflow opening is connected with pump; Inside between selections and the eddy flow section of scanning is divided to be respectively arranged with turbulence plate, floor from top to bottom.
The material of interference column body is lucite.
Pump is peristaltic pump.
The axis height of water inlet is higher than the axis height of underflow opening, and the axis being parallel of the axis of water inlet and underflow opening.
Turbulence plate is provided with three, from top to bottom equidistantly arranges.
Turbulence plate is cellular.
The beneficial effects of the utility model are: water inlet axis and the eddy flow section of scanning cylinder tangent, eddy flow can be produced after passing into current, add eddy flow centrifugal force field, by the centrifugal action in the eddy flow field of force, reinforcing particle presses density separation to a certain extent, high density coarse slime more effectively carries out sorting by centrifugal force field energy, again enter point selections at the coarse slime of point selections sorting not yet in effect and carry out sorting, be conducive to the displacement of different densities particle, be conducive to the upwards transport of cleaned coal particle, facilitate the fluency of particle displacement motion, thus significantly improve separating effect, make separator still can obtain good separating effect when pan feeding washability is poor, pass through discharge, the adjustment of discharge velocity and other parameters, the situation of separator can be adjusted easily according to the ature of coal situation of feed coal and the quality requirement of product, the accommodation of material size is large, strong adaptability, sharpness of separation is high, can effectively to wide rank, difficulty selects coarse slime to carry out sorting, meet the needs of actual production, simultaneously, the utility model structure is simple, simple operation, do not need outer adding medicine, flow process is simple, take up an area less, economy and durability, solve preferably the efficiency of separation and medicine consume between contradiction, effectively reduce cleans ash, decrease dense medium back of the body meeting phenomenon, add the clean coal yield of coal preparation plant, improve economic benefit.
