Abstract
The utility model discloses the spiral classifier that a kind of height of weir plate is adjustable, comprise spiral, log washer, helical axis, transmission device, lifting device, charging aperture, downflow weir, overfall and spigot.Wherein, spiral is arranged on the helical axis in the middle part of log washer, and helical axis two ends are supported by bearing, and the upper end of helical axis is provided with transmission device.Downflow weir is a sideboard, is close to groove inner wall in the groove that downflow weir is placed in body end.Lifting device is connected with downflow weir, improves or reduce the height of downflow weir by lifting device.Overfall is positioned at body least significant end, and desilting mouth is positioned at bottom log washer upper end.When requiring that in overflow, coarse fraction is more, suitably reduce height of weir plate, more coarse fraction is flowed out; When requiring that in overflow, fine fraction is more, suitably improving height of weir plate, making coarse fraction have longer time settlement.By regulating the height of downflow weir to reach partition size needed for production flexibly, improve classification efficiency.
Description
Technical field
The utility model relates to a kind of spiral classifier, particularly relates to the spiral classifier that a kind of height of weir plate is adjustable.
Background technology
Often need in ore-dressing technique that the ore pulp ground in grinding machine is given to spiral classifier and carry out classification.Existing spiral classifier mostly is fixed weir weir structure, and ore pulp feeds from charging aperture, and the classification band in log washer completes classification.Fine fraction product is drained from overfall with current through the downflow weir of trough end; Coarse fraction product, in the sedimentation of classification band, is then transported to outside the spigot discharge machine of trough upper end by spiral.Because coarse fraction product needs certain hour in the sedimentation of classification band, the too low meeting of height of weir plate causes a part of coarse fraction product not to be able to do in time sedimentation and discharging from downflow weir with current, and the too high meeting of height of weir plate causes fine fraction product can not discharge at overfall.Existing fixed weir weir structure well can not carry out classification to ore pulp, often affects normally carrying out of follow-up ore-dressing practice.
Summary of the invention
The purpose of this utility model is to provide the adjustable spiral classifier of a kind of height of weir plate, and this spiral classifier has the adjustable function of height of weir plate.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the spiral classifier that a kind of height of weir plate is adjustable, comprises spiral, log washer, helical axis, transmission device, lifting device, charging aperture, downflow weir, overfall and spigot.Wherein, spiral is arranged on the helical axis in the middle part of log washer, and helical axis two ends are supported by bearing, and the upper end of helical axis is provided with transmission device.Downflow weir is a sideboard, is close to groove inner wall in the groove that downflow weir is placed in body end.Lifting device is connected with downflow weir, improves or reduce the height of downflow weir by lifting device.Overfall is positioned at body least significant end, and desilting mouth is positioned at bottom log washer upper end.
The beneficial effects of the utility model are: when requiring that in overflow, coarse fraction is more, suitably reduce height of weir plate, and more coarse fraction is flowed out; When requiring that in overflow, fine fraction is more, suitably improving height of weir plate, making coarse fraction have longer time settlement.By regulating the height of downflow weir to reach partition size needed for production flexibly, improve classification efficiency.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Drawing illustrates: 1. spiral 2. log washer 3. helical axis 4. bearing 5. transmission device 6. lifting device 7. charging aperture 8. downflow weir 9. overfall 10. spigot 11. groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, but be not restriction the utility model.
With reference to accompanying drawing 1, the utility model comprises spiral 1, log washer 2, helical axis 3, transmission device 5, lifting device 6, charging aperture 7, downflow weir 8, overfall 9 and spigot 10.Wherein, spiral 1 is arranged on the helical axis 3 in the middle part of log washer 2, and helical axis 3 two ends are supported by bearing 4, and the upper end of helical axis 3 is provided with transmission device 5; Downflow weir 8 is a sideboard, is close to the inwall of groove 11 in the groove 11 that downflow weir 8 is placed in body end; Lifting device 6 is connected with downflow weir 8, can be improved or reduce the height of downflow weir 8 by lifting device 6; Overfall 9 is positioned at body least significant end, and desilting mouth 10 is positioned at the bottom of log washer 2 upper end.
During work, ore pulp feeds from material inlet 7, starts transmission device 5, transmission device 5 drives helical axis 3 to rotate, and then driving spiral 1 to rotate, ore pulp completes classification under the effect of spiral 1 in log washer 2, and fine fraction product is drained from overfall 9 with current through downflow weir 8; The sedimentation in log washer 2 of coarse fraction product, is then transported to log washer 2 upper end by spiral 1 and is discharged outside machine by spigot 10.When requiring that in overflow, coarse fraction product assay is more, suitably reduce height of weir plate, more coarse fraction product is flowed out; When requiring that in overflow, fine fraction product assay is more, suitably improving height of weir plate, making coarse fraction product have longer time settlement.
