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 by controlling to enter vent passages just can reach the grader of grading effect.
Background technology
Grader is widely used in being made into closed cycle journey point journey in ore dressing plant with ball mill and shunts ore deposit sand, or be used in gravity mill and come classification ore in sand form and thin mud, and in metal beneficiation flowsheet, grading is carried out to ore pulp, and the operation such as desliming, dehydration in washup operation.These facility have that structure is simple, reliable operation, the feature such as easy to operate.
The generic hierarchical machine of current extensive use is that material drops into after grader through feeder, and under the effect of classification swirling force, thickness powder is separated.This wherein has individual drawback to be exactly that wheel speed and wind-force size control stock grading simultaneously, and wheel rotation need consume comparatively 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 part, it is characterized in that: bottom the wall body of lower chamber, be provided with charging aperture and coarse fodder discharge port, rough classification mechanism is provided with at the connecting portion of lower chamber and middle cavity, rough classification mechanism is provided with Secondary Air air inlet, material dispersing device is provided with at the top of middle cavity, discharging opening is provided with in upper cavity, 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, be provided with and grading rotor sorting mechanism gas sealing mechanism one to one at the end face of upper cavity.Need the centrifugal force that produces at high-revolving grading rotor gentle in disclosed patent
Under the centripetal force effect that miscarriage is raw, 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 motor (3) that the impeller (2) of classification chamber (1) and drives impeller (2) are rotated, it is characterized in that: outside described classification chamber (1), be provided with the air intake passage (7) be communicated with classification chamber (1), the top of 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) is vertically arranged, the inwall of 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 coarse fodder and fines is separated under the airflow function of wheel rotation generation, and wheel rotation need consume very macro-energy.
Summary of the invention
The object of the present invention is to provide and a kind ofly only just can reach by controlling air quantity and wind speed the grader that coarse fodder is separated with fines, thus reduce the loss of energy, the cost of further minimizing enterprise.
Embodiments provide a kind of whirlwind clarifier, mainly comprise a classification chamber in back taper body, circular top plate is provided with at the top in classification chamber, fines outlet is provided with in the centre of circular top plate, the coarse fodder outlet of inclination is provided with at the cone angle place, bottom in classification chamber, one air intake passage is arranged on coarse fodder outlet classification chamber above, and charging aperture is plugged on air intake passage.
The action principle of this grader utilizes air intake passage to drive material to turn in chamber inward turning along the wind that classification chamber tangent line enters, and utilizes the centrifugal force of rotary wind and buoyancy to be rotated upwards by fine material.Thick material due to rotary centrifugal force effect and overcome buoyancy and at the bottom of flowing into downwards tin along wall in, discharge cavity further.This grader is back taper body, and wind speed reduces from bottom to top gradually, and the aerial buoyancy of material also gradually reduces.Only have the weight of material of certain fineness could discharge from the outlet of top fines lower than aerial buoyancy, thick material is due to upwards wind speed decreased, and buoyancy declines and sinks, thus reaches thickness feed separation, namely grading.Realize by controlling air intake passage wind speed size as the control of partition size size.
Further, the bottom gas leakage exported to prevent coarse fodder, destroys flow velocity and the flow direction of wind in classification chamber, arranges an only air-valve in one end of coarse fodder outlet.
Further, bottom classification chamber, centre installs " ten " font impeller, use driven by motor vane rotary, cause the effect to up-draught, effectively can prevent fines from falling classification chamber hypocone and divide reduction grading effect, " ten " font wheel rotation forms the wind to blowing up, and make fines upwards fly into classification chamber epicoele, the upwards flowing with rotary wind carries out classification to material.
Further, one end of air intake passage arranges wind-force regulation device, thus realizes the accurate control of air intake passage wind speed size.
This whirlwind clarifier adopts the classification chamber in back taper body, 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 the fines using this grader to be separated is narrower, and size distribution is more even.
