Abstract
The utility model discloses a hydraulic cyclone. The utility model effectively controls a short circuit current entering in an overflow product and the short circuit current entering in an underflow product by improving the exiting device. The utility model is characterized in that the lower part of an overflow pipe positioned on the lower side of a mine feeding pipe is provided with an annular convex object extending outwards along the periphery of the outer diameter of the overflow pipe. The inner cone wall within the length range of two third of a cone barrel body from top to bottom is provided with a line of horizontal concave rings. The device is suitable for the wet size grading operation and the solid-liquid separating operation of various materials. The utility model is especially suitable for size grading operation in the mineral dressing industry.
Description
The utility model relates in centrifugal force field the device of material by grading, particularly a kind of hydrocyclone.
The device more relevant with the utility model has: the field of force effect classifying cyclone of solid, liquid, gas three-phase stream relative motion simultaneously, China Patent No. 92205962.4; Cyclone separator, Chinese patent application publication number CN87105847A; Hydrocyclone, China Patent No. 91228157.X.When above classifying equipoment is used,, worsened grading effect owing to have short-circuit flow under the lid that directly enters without grading in the overflow product and directly enter short-circuit flow in the underflow product without grading.So the thickness grain mixes seriously in present hydrocyclone overflow and the underflow product, classification efficiency is not high.Chinese patent 91228157.X addresses the above problem on the internal cone wall of device lower cone cylindrical shell to be provided with one group of annulus groove, and classification efficiency has obtained certain raising in the paper pulp removal of impurities that is applied to paper industry.But this patent is not suitable for the graded operation of mining processing industry.Because near the annulus groove its heavy ends outlet will exceedingly destroy in the cyclone, near the Flow Field Distribution the sand setting mouth, be unfavorable for the improvement of grading effect.
The purpose of this utility model is to provide a kind of improved hydrocyclone, improves the classification efficiency of device now.
The purpose of this utility model is achieved in that
Hydrocyclone comprises cylindrical tube (1), conic tube (2), mineral-feeding pipe (3), overflow pipe (4), sand setting mouth (5), it is characterized in that the overflow pipe bottom that is positioned at the mineral-feeding pipe below has along overflow pipe external diameter periphery outward extending ring-type ridge (6).Its effect is to stop directly to converge with upwelling along short-circuit flow under the lid from top to bottom of the overflow pipe outside to enter overflow, and minimizing enters the short circuit flow rate in the overflow product.
Another kind of solution is that above-mentioned hydrocyclone structure is constant, comprise that also cylindrical tube (1), conic tube (2), mineral-feeding pipe (3), overflow pipe (4), sand setting mouth (5), overflow pipe bottom have ring-type ridge (6), have the horizontal scrobicular ring of row (7) on the internal cone wall in conic tube 2/3rds length ranges from top to bottom in addition.
The utility model shows that with the existing apparatus comparative test result only having the ring-type ridge in the overflow pipe bottom can improve classification efficiency 7～9%, if scrobicular ring is set on the internal cone wall again, can improve classification efficiency 13～15%.
Accompanying drawing 1 is the structural representation of hydrocyclone;
Accompanying drawing 2 is I-I profiles of Fig. 1.
Below in conjunction with accompanying drawing more detailed description embodiment of the present utility model.
Ring-type ridge (6) on the overflow pipe of this hydrocyclone (4) is a collar that is fixed on the overflow pipe bottom, cover ring width X
1Optimum valuing range be 0.02～0.09D, wherein D represents the internal diameter of cyclone cylindrical portions may.In the alternative plan, also having the horizontal scrobicular ring of row (7) on the internal cone wall of conic tube (2), can be continuous between the scrobicular ring, also can be interrupted.The band scrobicular ring partly occupy conic tube from top to bottom length 3/5ths, the scrobicular ring cross section is a triangle, scrobicular ring degree of depth X
2Optimum range be 0.024～0.048D, D represents the internal diameter of cylindrical portions may.
Claims (4)
1, a kind of hydrocyclone, it comprises: cylindrical tube (1), conic tube (2), mineral-feeding pipe (3), overflow pipe (4), excellent sand mouth (5) is characterized in that the overflow pipe bottom that is positioned at the mineral-feeding pipe below has along overflow pipe external diameter periphery outward extending ring-type ridge (6).
2, hydrocyclone according to claim 1 is characterized in that said ring-type ridge (6) is a collar that is fixed on the overflow pipe bottom, cover ring width X
1Be 0.02～0.09D, wherein D represents the internal diameter of cyclone cylindrical portions may.
3, hydrocyclone according to claim 1 is characterized in that on the internal cone wall in said conic tube (2) 2/3rds length ranges from top to bottom Yi Lieshui (plano-concave ring (7) being arranged.
4, hydrocyclone according to claim 3 is characterized in that the scrobicular ring cross section on the said internal cone wall is a triangle, scrobicular ring degree of depth X
2Be 0.024～0.048D, D still represents the internal diameter of cyclone cylindrical portions may.
