Empty cavity, the cyclone cylindrical section top are provided with overflow port, and the bottom of rotary table section is provided with underflow under the cyclone
Mouthful, the cyclone feed inlet that will be connected to inside and outside cavity, circle on the cyclone are connected on the side wall of the cyclone cylindrical section
Cleaning water ring is provided under platform section and cyclone between rotary table section, is connected with cleaning water inlet on the outer wall of the cleaning water ring,
It cleans on the inner wall of water ring and is provided with cleaning water outs, the cleaning water inlet, cleaning water ring and cleaning water outs will be in cavitys
Outer connection, and constitute secondary cleaning aquaporin.
Further, the cyclone feed inlet is accessed along the tangent line or helical of cyclone cylindrical section circumference.
Further, the cleaning water inlet is fed along the tangent line of cleaning water ring circumference.
Further, the cleaning water outs communicate along the tangential direction of cleaning water ring circumference and cavity.
Preferably, the cleaning water outs are one or more.
A kind of fine grading method of secondary cleaning type classifying cyclone, suspension spin current device feed inlet is along cyclone circle
The tangent line or helical of shell of column are tangentially fed in cavity, and the intracorporal suspension of chamber forms the composite screw whirlpool fortune of contour stealth and inward eddy
Dynamic, the coarse granule in suspension is sunk under the action of the centrifugal force to cyclone inner wall, and gradually forms sedimentary, thin in suspension
Particle and fluid media (medium) enter inward eddy and are discharged from overflow port;From the cleaned water ring of water flow that tangentially feeds of cleaning water inlet and
Cleaning water outs and sedimentary rotating Vortex, are incorporated in sedimentary, so that sedimentary is superimposed the centripetal confluence movement an of radial direction, lead to
Seepage flow or the effect of secondary fluidised formization are crossed, the fine grained in sedimentary is taken in inward eddy, is discharged from overflow port, reduces and reaches bottom
Fine particle content in head piece sedimentary.
The utility model has the advantages that secondary cleaning type classifying cyclone provided by the invention and its method can effectively prevent fine grained to exist
It is polluted in coarse granule, in the centrum section of cyclone, introduces new medium water flow along direction of rotation, cylindrical section and upper cone section are formed
Sedimentary carry out secondary fluidization or seepage flow cleaning, bring the fine grained therein wherein carried secretly into inward eddy, and finally with
Overflow discharge, achieving the purpose that, which reduces underflow, presss from both sides carefully and improves effectiveness of classification.

Specific embodiment
The present invention will be further explained with reference to the accompanying drawing.
As shown in Figure 1-3, a kind of secondary cleaning type classifying cyclone, including sequentially connected cyclone cylinder from top to bottom
Section 1, rotary table section 3 under rotary table section 2 and cyclone on cyclone, rotary table section 2 and eddy flow on the cyclone cylindrical section 1, cyclone
Rotary table section 3 forms hollow cavity under device, and overflow port 5, rotary table under the cyclone are provided at the top of the cyclone cylindrical section 1
The bottom of section 3 is provided with underflow opening 6, is connected with the cyclone that will be connected to inside and outside cavity on the side wall of the cyclone cylindrical section 1
Feed inlet 4 is provided with cleaning water ring 8, the cleaning water ring 8 between rotary table section 3 under rotary table section 2 and cyclone on the cyclone
Outer wall on be connected with cleaning water inlet 7, clean on the inner wall of water ring 8 and be provided with cleaning water outs 9, the cleaning water inlet 7,
Cleaning water ring 8 will be connected to cleaning water outs 9 inside and outside cavity, and constitute secondary cleaning aquaporin, in particular, the cyclone
The diameter of cylindrical section 1 is equal to the diameter of 2 upper surface of rotary table section on cyclone, the diameter of 2 lower end surface of rotary table section on the cyclone
