At present, in the classification and sorting process technology of mineral processing at home and abroad, big-and-middle-sized ore dressing plant is substantially all using rotation Stream device is classified, and uses the techniques such as spiral chute to carry out reselection operation.
Cyclone is formed by connecting by hollow cylinder and circular cone, inserts an overflow pipe at the center of cylinder, tangentially side To mineral-feeding pipe is connected to, dirt sand mouth is left in the bottom of cone.Its operation principle is:Ore pulp enters along mineral-feeding pipe under pressure After entering cyclone, make gyration under the limitation of cylindrical wall.Under the influence of centrifugal force, coarse granule is thrown near wall, And as external spiral stream is discharged by bottom;Fine grained is trapped in inside spin stream, arranged by overflow pipe because centrifugal sedimentation speed is small Go out.External spiral stream constantly expands in flowing downward, and is full of overflow pipe lower periphery whole region, and a portion is directly entered Enter into overflow pipe, turn into short-circuit flow.Coarse granule can be brought directly in overflow by short-circuit flow, reduce classification efficiency.It, which has, divides Stage efficiency is high, and floor space is small, does not have the advantages that moving component, but be the shortcomings that cyclone:Fluctuation of service, due to its knot The defects of structure, there is short-circuit flow phenomenon, cause to be mingled with coarse granule in overflow fine grained product, reduce classification efficiency.
One narrow and long open slot is bent into curl around vertical axis, just forms spiral chute.Its main body work It is a spiral shaped openings cell body as part.Spiral chute is that choosing point is carried out to ore pulp by gravity, after ore pulp is fed from top, in weight Under power effect, during being flowed downward along chute, particle swarm is layered in ore pulp, the transverse direction of the heavy suite of bottom along bottom land The gradient is moved to the inner edge of groove, and final concentrate is formed in cell body end;Light mineral particle positioned at upper strata is then with revolution flowing Ore pulp is moved downward along on the outside of groove, and mine tailing discharge is finally formed in the end of groove.Its advantage is movement-less part, operation letter Single, cost is cheap;But its beneficiating efficiency is low, disposal ability is small, long flow path, and floor space is big, can only handle relatively crude Grade mineral, application are narrower etc..
The content of the invention
The shortcomings that in order to overcome existing preparation equipment to exist, the present invention propose a kind of spiral-shaped cyclone.The eddy flow Device carries out ore dressing by setting spiral cavity on the support columns, by spiral cavity, solves the technical problem of Mineral Classification.
Scheme is used by the present invention solves technical problem:
By being fixedly connected with spiral cavity centered on support column, spiral cavity is by the second circular cavity of inner side and first circle in outside Shape chamber forms, spiral cavity opening be provided with ore inlet port, the first circular cavity and the second circular cavity by triangular chamber with it is thick The outlet of grain ore deposit, intermediate particle outlet and particulate ore deposit outlet.
Good effect, the present invention is simple in construction, and floor space is small, and ore dressing is high with classification efficiency.Suitably it is used as preparation equipment Using.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
In figure, 1. support columns, 2. spiral cavities, 3. ore inlet ports, 4. first circular cavities, 5. second circular cavities, 6. triangles Chamber, the outlet of 7. coarse grain ore deposits, the outlet of 8. intermediate particles, the outlet of 9. particulate ore deposits.
Embodiment
Illustrate the embodiment of the present invention below in conjunction with the accompanying drawings.
As illustrated, by being fixedly connected with spiral cavity 2 centered on support column 1, spiral cavity is second circular by inner side Chamber 5 and first circular cavity 4 in outside form, and spiral cavity opening is provided with ore inlet port 3, the first circular cavity and the second circle Chamber is connected by triangular chamber 6 and coarse grain ore deposit outlet 7, intermediate particle outlet 8 with particulate ore deposit outlet 9.
The ore inlet port is connected by adpting flange with mineral-feeding pipe, and ore inlet port is arranged on the top, close of spiral cavity Position at support column;
The intermediate particle outlet and the outlet of coarse grain ore deposit are arranged on the bottom of spiral cavity, close to the edge position of spiral cavity Put;
Described particulate goes out mine mouth and is connected by flange with particulate ore deposit efferent duct;
Described intermediate particle ore deposit outlet is connected by flange with intermediate particle ore deposit efferent duct;
Described coarse grain ore deposit outlet is connected by flange with coarse grain ore deposit efferent duct.
Operation principle:
When ore pulp to be separated is entered in spiral cavity with certain pressure from the ore inlet port of spiral cyclone, then it is forced to make Gyration.Because the centrifugal force that it is subject to is of different sizes, the coarse granule in ore pulp overcomes the resistance of water to enter cross section for circle The intermediate particle enrichment region and coarse granule enrichment region of shape chamber, decline along the cavity wall spiral of this circular cavity, until under spiral cavity Portion, is exported by intermediate particle ore deposit respectively and intermediate particle ore deposit efferent duct and the outlet of coarse grain ore deposit and coarse grain ore deposit efferent duct enter lower road Process.Centrifugal force is smaller suffered by fine grained, is similar triangular chamber in cross section under the collective effect of gravity and water flow pressure Fine grained enrichment region inside spin decline, until spiral cavity bottom, exported by particulate ore deposit and particulate ore deposit efferent duct enter Next procedure, so as to reach the purpose of classification.
The present invention can not only be used for classifying equipoment, but also as sorting equipment.During as classifying equipoment, compared with cyclone, Short-circuit flow is thoroughly avoided, improves effectiveness of classification, increases graded product, classification efficiency is high.During as sorting equipment, slipped with spiral Groove is compared, and floor space is small, and disposal ability is stronger, and processing grade is wide, can handle micro-size fraction mineral.
Feature:
Its structure integrates the design feature of cyclone and spiral chute, i.e. ore pulp is entered by ore inlet port under the effect of the pressure In spiral cavity, it is forced to do gyration.During spiral declines, because the centrifugal force that it is subject to is of different sizes, ore pulp In coarse granule overcome water resistance enter most edge cross section be circular cavity coarse granule enrichment region, along the chamber of this circular cavity Wall spiral declines, until the bottom of spiral cavity, is exported by coarse grain ore deposit and coarse grain ore deposit efferent duct enters next procedure.In ore pulp Intermediate particle overcome water resistance enter near-end cross section be circular cavity intermediate particle enrichment region, along the chamber of this circular cavity Wall spiral declines, until the bottom of spiral cavity, is exported by intermediate particle ore deposit and intermediate particle grain ore deposit efferent duct enters lower road Process.Centrifugal force is smaller suffered by fine grained, is subtriangular chamber in cross section under the collective effect of gravity and water flow pressure Fine grained enrichment region inside spin decline, until spiral cavity bottom, exported by particulate ore deposit and particulate ore deposit efferent duct enter Next procedure, so as to reach the purpose of classification.
