Abstract

An embodiment of the invention discloses a cyclone grader which mainly comprises a grading cavity in the shape of an inverted cone. A round top plate is arranged at the top of the grading cavity, a fine material outlet is arranged in the middle of the round top plate, an inclined coarse material outlet is arranged at a cone corner of the lower portion of the grading cavity, an air incoming passage is arranged on the grading cavity above the coarse material outlet, and a feeding port is connected on the air incoming passage in an inserted manner. The grading cavity which is in the shape of the inverted cone is adopted, so that a conventional barrel portion is omitted; compared with the fact that air speed of an existing grader is constant, the cyclone grader can effectively utilize the characteristic that air speed gradually decreases in the cyclone grader to realize separation of coarse and fine materials. Fine materials separated by using the cyclone grader are narrow in particle size distribution span and uniform in particle size distribution.

Description

A kind of whirlwind clarifier
Technical field
The present invention relates to grader, a kind of whirlwind clarifier of specific design, particularly a kind of wind speed that enters vent passages by control just can reach the grader of grading effect.
Background technology
Grader is widely used in being made into closed cycle journey point journey shunting ore deposit sand with ball mill in ore dressing plant, or be used in and in gravity mill, come classification ore in sand form and thin mud, and in metal beneficiation flowsheet, ore pulp is carried out to grading, and the operation such as the desliming in washup operation, dehydration.That these facility have is simple in structure, reliable operation, the feature such as easy to operate.
The generic hierarchical machine of at present extensive use be material after feeder drops into grader, under the effect of classification vortex power, thickness powder separates.This wherein has individual drawback is exactly that wheel speed and wind-force size are controlled stock grading simultaneously, and wheel rotation need consume compared with macro-energy.
The patent No. is that the Chinese utility model patent of CN203108798U discloses a kind of horizontal ultra-fine many rotator sorters, comprise body, its inner chamber is divided into upper cavity from top to bottom, middle cavity and lower chamber three parts, it is characterized in that: the wall body bottom at lower chamber is provided with charging aperture and coarse fodder discharge port, at the connecting portion of lower chamber and middle cavity, be provided with rough classification mechanism, rough classification mechanism is provided with Secondary Air air inlet, top at middle cavity is provided with material dispersing device, in upper cavity, be provided with discharging opening, discharging opening is opened on the end face of upper cavity, equally spacedly on the sidewall of upper cavity be provided with six grading rotor sorting mechanisms, the end that grading rotor sorting mechanism is positioned at discharging opening is provided with labyrinth flat board, at the end face of upper cavity, be provided with and grading rotor sorting mechanism gas sealing mechanism one to one.The centrifugal force that need to produce at high-revolving grading rotor in disclosed patent is gentle
Under the centripetal force effect of miscarriage life, complete the separation of large or fine granule, consume energy very large.
The patent No. is that the Chinese invention patent of CN101862730A discloses a kind of cyclosizer, comprise classification chamber (1), be positioned at the impeller (2) of classification chamber (1) and the motor (3) that drives impeller (2) is rotated, it is characterized in that: the outer air intake passage (7) being communicated with classification chamber (1) that is provided with in described classification chamber (1), the top in described classification chamber (1) is provided with charging aperture (4), bottom is provided with coarse fodder outlet (5), axial end is provided with fines outlet (6), the rotating shaft (21) of described impeller (2) vertically arranges, the inwall in described classification chamber (1) is provided with spiral material channel (11) around in impeller (2), described charging aperture (4) is arranged on the top of spiral material channel (11), described coarse fodder outlet (5) is arranged on the bottom of spiral material channel (11).In disclosed patent, grader is under the airflow function producing in wheel rotation, coarse fodder and fines to be separated, and wheel rotation need consume very macro-energy.
Summary of the invention
The object of the present invention is to provide a kind of control air quantity that only depends on just can reach the coarse fodder grader Fen Li with fines with wind speed, thereby reduce the loss of energy, further reduce the cost of enterprise.
The embodiment of the present invention provides a kind of whirlwind clarifier, mainly comprise a classification chamber that is back taper body, top in classification chamber is provided with circular top plate, in the centre of circular top plate, be provided with fines outlet, at cone angle place, the bottom in classification chamber, be provided with the coarse fodder outlet of inclination, one air intake passage is arranged on coarse fodder and exports on classification chamber above, and charging aperture is plugged on air intake passage.
The action principle of this grader is to utilize the wind that air intake passage enters along classification chamber tangent line to drive material to turn in chamber inward turning, utilizes the centrifugal force of rotary wind and buoyancy that thin material is rotated upwards.Thick material is due to rotary centrifugal force effect and overcome buoyancy and at the bottom of flowing into tin along wall, further discharge cavity downwards.This grader is back taper body, and wind speed reduces from bottom to top gradually, and the aerial buoyancy of material also gradually reduces.The weight of material that only has certain fineness could be discharged from the outlet of top fines lower than aerial buoyancy, and thick material is due to wind speed decreased upwards, and buoyancy declines and sinks, thereby reaches thickness feed separation, namely grading.As for the control of partition size size is realized by controlling air intake passage wind speed size.
Further, in order to prevent the bottom gas leakage of coarse fodder outlet, destroy flow velocity and the flow direction of wind in classification chamber, an only air-valve is set in one end of coarse fodder outlet.
Further, in bottom, classification chamber, centre is installed " ten " font impeller, use driven by motor vane rotary, cause the effect to up-draught, can effectively prevent that fines from falling classification chamber hypocone and dividing reduction grading effect, " ten " font wheel rotation forms the wind to blowing up, makes fines upwards fly into classification chamber epicoele, upwards flowing material is carried out to classification with rotary wind.
Further, one end of air intake passage arranges wind-force regulation device, thereby realizes the accurate control of air intake passage wind speed size.
This whirlwind clarifier adopts the classification chamber that is back taper body, do not there is traditional cylindrical portions, and compared with immobilizing with the wind speed of existing grader, the characteristic that point grader can effectively utilize air velocity to reduce gradually in this grader, thus realize the separation of thickness material.The size distribution span of fines of using this grader to separate is narrower, and size distribution is more even.
