Abstract
The invention relates to a novel heavy medium cyclone, solving the problems of blockage and increasing overflow of a bottom flow port of an ordinary cyclone. The novel heavy medium cyclone is characterized in that a tapered cylindrical cyclone with a tapered flared port is arranged, wherein the upper body of the tapered cylindrical cyclone adopts a cylinder 2, the middle section of the tapered cylindrical cyclone adopts a cone 4, the lower part of the tapered cylindrical cyclone is provided with a flared bottom flow section 5, the side end of the cylinder 2 is provided with a feeding port 1, the center of the top end of the cylinder 2 is provided with an overflow tube 3, a bottom flow port adjusting device 6 is arranged in the flared port of the bottom flow section 5 and is provided with a lower tapered flared port, and the cylinder 2 of the upper body, the cone 4 of the middle section and the flared bottom flow section 5 of the lower part can be sequentially connected in a sealing way through connecting plates on the respective edges and are fixed via bolts 8. The invention has the advantages that the accuracy of separation of coal particles can be improved, the lower limit of separation can be reduced, the pressure can be regulated, and the separation effect of the cyclone can be improved. The novel heavy medium cyclone is suitable for applications in separation of coal and other minerals based on the density.
Description
Affiliated technical field:
The invention belongs to sorting machine equipment manufacturing technology field, mine, be specifically related to a kind of new type heavy medium cyclone, be applicable to using of coal and other mineral by density separation.
Background technology:
Mainly there are defectives such as the underflow opening size can not onlinely be regulated, lower limit of separation high, the air cylindricality is strong and size is unstable and can not regulate in present heavy medium cyclone.Can not well satisfy to obtain higher underflow density, the double requirements of lower effluent concentration is arranged again simultaneously.
Summary of the invention:
The object of the invention remedies above deficiency exactly; What provide is a kind of under the condition of identical feed pressure; Can effectively reduce lower limit of separation, the raising sharpness of separation of coal; Especially the separating effect to fine fraction coal (3-0mm) obviously improves, the new type heavy medium cyclone that simultaneously the variation applicability of pan feeding is strengthened.
The present invention realizes that affiliated new type heavy medium cyclone, structure are provided with mainly to be made up of pan feeding section, shell of column, awl section, overflow pipe, underflow section and underflow opening adjusting device six major parts.It is characterized in that being provided with a upper body is cylinder 2; The stage casing is a cone 4; The bottom is set to a cone horn mouth circular cone Tong cyclone of horn mouth underflow section 5, is provided with feeding mouth 1 at cylinder 2 sides, outside the center, top of cylinder 2 is provided with in the lower cone on centrum benefit stream pipe 3; A underflow opening tunable arrangement 6 is set in the horn mouth of underflow section 5, and it is lower cone horn body mouth that underflow opening tunable arrangement 6 is provided with.The lower limb of upper body cylinder 2 is provided with terminal pad 7, and cone 4 top edges in stage casing are provided with terminal pad 9, and cone 4 lower limbs in stage casing are provided with terminal pad 10; Underflow section 5 top edges are provided with terminal pad 11; The lower limb terminal pad 7 of upper body cylinder 2 docks with stage casing cone 4 top edge terminal pads 9, and fixing with bolt 8, stage casing cone lower limb terminal pad 10 docks with underflow section top edge terminal pad 11; Fixing with bolt 8, the shaping work principle also can directly be welded as a whole
Ore pulp feeds cyclone with certain pressure along tangent line; Under the constraint of cyclone inwall; Ore pulp is done external spiral motion downwards at a high speed, because the continuous contraction of awl section bore, the discharge of underflow opening is restricted; The ore pulp that a feasible part is done screw downwards is folded near arriving underflow opening the time and upwards does the inside spin motion, finally discharges from overfall.At the centrifugal force of rotation flow with radially under the resistance acting in conjunction; Solid particle can the layering according to its granularity (density) difference, and the particle that granularity is big and density is high is in outermost layer, discharges from underflow opening with external spiral stream; The particle that fine size and density are little is positioned at the innermost layer; Discharge from overfall with rising inside spin flow, the mediate particle of state of granularity and density will be positioned at the middle part of cyclone, get into underflow or overflow at random.
New type heavy medium cyclone of the present invention, it is close with common hydrocyclone to have a underflow density, but effluent concentration can reduce, and run thick phenomenon and reduce, and underflow density is relatively stable, and fluctuation range is little, the advantage that underflow density is effective.
