Description
Technical field
The gravity treatment that the invention belongs to different specific weight mineral is not standby, and suitable sorting granularity is the sludge of 100 microns ~ 5 microns.
Background technology
The sludge of current sorting different specific weight, mainly adopt belt chute, shaking table, even groove etc., it is little to there is disposal ability in them, and floor space is large, water consumption is large, process mineral granularity is large, safeguard the problems such as loaded down with trivial details, capital expenditure and producing cost height.Sorting is carried out for many years as adopted shaking table, although people did many improvement to equipment, but still continue to use structural principle in the past, therefore in minimizing power consumption and floor space, expand disposal ability aspect effect desirable not enough, especially fine-graded mineral disposal ability is always difficult to improve.
In order to deficiencies such as the volume solving the above-mentioned existence of existing preparation equipment are large, sorting granularity is large, water consumption is many, the present inventor proposes the technical scheme of " suspended vibrating concentrating machine with conical surface " (application number 200820228923.2) in by patent document, the sorting face of this equipment is the disk conical surface of 3 ° ~ 10 °, while moving in a circle along round circular orbit, driven to do by eccentric pendulum mechanism and vibrate.Really fewer than traditional above-mentioned preparation equipment water consumption in the application of reality, floor space is little, long service life, accessible mineral granularity is little, concentration ratio is high, but inventor also finds that there is part microfine heavy mineral and is rinsed loss by washings, make the rate of recovery of mineral and concentration ratio have some to reduce, therefore structure further rationally, the rate of recovery and concentration ratio also need to improve on improving further.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of suspended vibrating concentrating machine with conical surface, and the design of its motion is more reasonable, and sorting granularity can reach the sludge of 100 microns ~ 5 microns, 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 in sorting face is 3 ° ~ 15 °, it is characterized in that: the blanking device installed above sorting face in the middle part of the conical surface extends to the involute washing pipe of sorting face outer rim, uniform weeper on pipe, one matsurface trapping district is set at sorting face outward flange, concentrate wash tub pipe is installed and the uniform spray orifice facing to sorting face rotation direction on pipe at the end of involute washing pipe.
The tapered cross-section in sorting face is with the evagination radian of radius of curvature 30m ~ 60m, and sorting face outer rim trapping sector width is 100mm ~ 360mm, and roughness is Ra100um ~ Ra500um.
Weeper on involute washing pipe is apart from being 4mm ~ 15mm, and aperture is 0.3mm ~ 1mm; Concentrate wash tub pipe is provided with long and short each one, and spray orifice pitch-row is 4mm ~ 10mm, and aperture is 0.3mm ~ 1mm.
The invention has the beneficial effects as follows:
1, the involute washing pipe of the aperture that is evenly distributed is adopted, the ripples from top to bottom that water droplet can be formed on the sorting face of conical surface lathe bed, in point constituency, mineral are had to the effect of rushing and catching up with, in the middle of the process that the mineral being deposited on point constituency are flowed downward, repeatedly eluriated, light mineral flow velocity comparatively fast enters in mine tailing, and heavy mineral obtains further enrichment in flowing from top to bottom, and such washing pipe structural configuration can improve concentration ratio 5 to 10 times than uninstalled equipment.
2, the rough and uneven in surface coarse structure in district is trapped; there is the effect of storage at sunk part, have protection storage effect to fine heavy mineral, avoid because washings rinse rear loss; thus improve the rate of recovery and concentration ratio, compare and do not use the equipment in coarse trapping district can improve the rate of recovery 10% ~ 15%.
3, concentrate wash tub pipe is divided into two, and long tube can play punching to heavy mineral residual on point constituency and catch up with effect, and the heavy mineral of short tube to enrichment in trapping district works the effect of catching, and two pipes are collaborative to be made to be deposited on heavy mineral on sorting face and reclaim more thoroughly.
4, the sorting face by the original pure conical surface is improved to the curvature that band is certain, the uniformity of the distribution of ore pulp on sorting face first can be made to improve, thus avoid the appearance of drawing ditch phenomenon, improve the efficiency of separation and sharpness of separation; Next enhances the intensity in 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.
