A separation surface of the concentrating machine is provided with vibrating and rotating mechanisms, the gradient of a conical surface of the separation surface is 3-15 degrees, an involute washing pipe which extends from an unloading device at the middle part of the conical surface to the outer edge of the separation surface is arranged above the separation surface, water dripping holes are uniformly distributed on the involute washing pipe, the outer edge of the separation surface is provided with a rough-surface catching area, the tail end of the involute washing pipe is provided with a concentrate washing pipe, and spray holes facing the rotating direction of the separation surface are uniformly distributed on the concentrate washing pipe. The concentrating machine has the advantages of finer separation particle size, less water consumption, small occupied area and long service life; the movement mechanisms are designed reasonably; and the concentrating machine can be easily manufactured in large scale and is convenient for transportation and installation.
Description
Technical field
The gravity treatment that the invention belongs to the different specific weight mineral is not equipped with, and suitable sorting granularity is 100 microns～5 microns a sludge.
Background technology
The sludge of sorting different specific weight mainly adopts belt chute, shaking table, even groove etc. at present, and they exist disposal ability little, and floor space is big, water consumption is big, the processing mineral granularity is big, it is loaded down with trivial details to safeguard, problems such as capital expenditure and producing cost height.As adopt shaking table to carry out sorting for many years; Although people did many improvement to equipment, but still continue to use structural principle in the past, therefore reducing power consumption and floor space; It is desirable not enough to enlarge disposal ability aspect effect, always is difficult to improve for fine-graded mineral disposal ability especially.
In order to solve deficiencies such as the volume that has the above-mentioned existence of preparation equipment now is big, the sorting granularity is big, water consumption is many; The inventor has proposed the technical scheme of " suspended vibrating concentrating machine with conical surface " (application number 200820228923.2) in through patent documentation; The sorting face of this equipment is 3 °～10 ° the disk conical surface; When round circular orbit moves in a circle, drive by eccentric pendulum mechanism and to do vibration.In the application of reality, lack than traditional above-mentioned preparation equipment water consumption really; Floor space is little; Long service life, accessible mineral granularity is little, concentration ratio is high, but the inventor has found that also part microfine heavy mineral is washed the water flushing and runs off; Make the rate of recovery and the concentration ratio of mineral have some to reduce, therefore structure further rationally, the rate of recovery and concentration ratio also need improve on further improving.
Summary of the invention
Technical problem to be solved by this invention provides a kind of suspended vibrating concentrating machine with conical surface, and its motion design is more reasonable, and the sorting granularity can reach 100 microns～5 microns sludge, and water consumption is few, and floor space is little, and service life of equipment is long.
Solving the scheme that technical problem of the present invention adopts is: vibration and rotating mechanism have been worn in sorting; The conical surface gradient of sorting face is 3 °～15 °; It is characterized in that: the involute washing pipe that extends to sorting face outer rim from the blanking device at conical surface middle part is installed above sorting face; Be uniformly distributed with weeper on the pipe, capture the district, install on concentrate wash tub pipe and the pipe at the end of involute washing pipe and be uniformly distributed with spray orifice facing to sorting face rotation direction at one matsurface of sorting face outward flange setting.
The tapered cross-section of sorting face has the evagination radian of radius of curvature 30m～60m, and it is 100mm～360mm that sorting face outer rim captures sector width, and roughness is Ra100um～Ra500um.
Weeper on the involute washing pipe is apart from being 4mm～15mm, and the aperture is 0.3mm～1mm; The concentrate wash tub pipe is provided with long and short each one, and the spray orifice pitch-row is 4mm～10mm, and the aperture is 0.3mm～1mm.
The invention has the beneficial effects as follows:
1, adopts the involute washing pipe of the aperture that is evenly distributed; The ripples from top to bottom that water droplet can form on the sorting face of conical surface lathe bed have mineral in minute constituency and to dash the effect catch up with, and make in the middle of the process that the mineral that are deposited on the branch constituency flow downward; Eluriated repeatedly; The light mineral flow velocity comparatively fast gets in the mine tailing, and heavy mineral obtains further enrichment in flowing from top to bottom, and such washing pipe structural configuration can improve 5 to 10 times of concentration ratios than uninstalled equipment.
2, capture the rough and uneven in surface coarse structure in district; At sunk part the effect of taking in is arranged, have protection to take in effect, avoid running off because of washings flushing back to fine heavy mineral; Thereby improve the rate of recovery and concentration ratio, compare and do not use the equipment in coarse capture district can improve the rate of recovery 10%～15%.
3, the concentrate wash tub pipe is divided into two, and long tube can work the effect of catching up with of dashing to residual heavy mineral on minute constituency, and short tube is gone up the heavy mineral of enrichment and worked the effect of catching capturing the district, and two pipes are collaborative to be made and be deposited on that heavy mineral reclaims more completely on the sorting face.
4, be improved on the sorting face by the original pure conical surface with certain curvature, the uniformity of the distribution of ore pulp on sorting face is improved, thereby avoided drawing the appearance of ditch phenomenon, improved the efficiency of separation and sharpness of separation; Next has strengthened the intensity of sorting face, and can improve the disposal ability of unit, better improves the index of the rate of recovery and concentration ratio compared with original equipment.
