If the too high viscosity that will lead to this fluid of the sludge concentration of sand mud mixed liquor is too high, sand grains is caused only to rely on power for support Can not precipitation and separation easily, unless reduce its viscosity the dilution of sand mud mixed liquor increasing amount clear water and be conducive to sand mud and separate, But it will lead to 1 volume great Fu of washed-out sand cylinder increase with the substantial increase of rate of water added and quantity of circulating water also need synchronous increase, face To high concentration material, its function is just slightly insufficient not appropriate, as shown in figure 20, can be mixed at this time with pressure pumping to sand mud Liquid pressurization high speed injection liquid spigot (CYCLONE), this pressurization sand mud mixed liquor 69 borrow high speed rotation to generate after injecting liquid spigot 70 Centrifugal force be divided into the rotation magma (66) containing sand and the rotation thin liquid 65 containing mud, wherein rotation thin liquid 65 flow much larger than revolve it is dilute Liquid 65, at this time by containing highly enriched silt particle rotation magma 65 import silt particle cylinder 1 carry out washed-out sand operation, due to its flow compared with Sand mud mixed liquor quantity great Fu before the original centrifugal force separate without pressure is reduced, therefore in identical washed-out sand clear water, The viscosity for being greatly lowered related sand mud mixed liquor is reduced and can easily be divided sand mud conducive to power is only relied on for support by its sludge concentration From and have optimal separation effect, and be not required to improve cleaning water and space occupied.

The sand mud mixed liquor as shown in Figure 19,20,21 is pressurized with pressure pumping and imports liquid spigot 70, this sand along forcing pipe 67 Mud mixed liquor is imported along Archimedian vortex filament shape vortex tube 60, by this pipe guiding with asymptotic whirling streamline in leading coil 61 Interior high speed is rotated down, and the main vortex 63 of this backspin is during being rotated down because accelerating the caliber of Taper Pipe 62 is tapered to make its flowing Resistance is cumulative, when it is main vortex 63 flow downward resistance be equal to sand mud mixed liquor internal pressure when then 63 downward flow velocitys of main vortex be equal to Zero, it is generated in upwards to the guide wire 68 for belonging to low-pressure side then and is vortexed 64 discharge liquor spigots 70, in main vortex 63 and interior vortex 64 The biggish suspended sludge particle of specific gravity and partial size in rotary course in sand mud mixed liquor is influenced and past acceleration by rotary centrifugal force The tube wall of Taper Pipe 62 is rotated down, and small suspended sludge particle is because the centrifugal force of rotation is lower than the electrostatic between mud granule Repulsion is still suspended in the main vortex 63 of backspin, the patch tube wall rotation when the main 63 downward flow velocity of arrival of vortex null position Specific gravity or the higher mud granule of partial size, which are still affixed on, accelerates the rotation of 60 inner wall of Taper Pipe will not be with the interior vortex in main 63 center of vortex 64 rotations upwards, this mud granule borrow the internal pressure for accelerating Taper Pipe 62 and are self-possessed to backspin discharge liquor spigot and are suspended in main vortex The small suspended particulates of partial size in 63 are then with 64 upward discharge liquor spigots 70 of interior vortex, thus by the rotation sub-sieve choosing of sand mud mixed liquor At partial size rotation magma 66 of different sizes and rotation thin liquid 65, wherein the particle size of rotation magma 66 is higher than rotation thin liquid 65, but revolve thick The sludge concentration that liquid 66 includes between the two with rotation thin liquid is similar.Liquid spigot 70 borrow itself high speed rotation of its fluid generate from Mixed liquor screening is divided into rotation magma 66 and rotation thin liquid 61 by mental and physical efforts, wherein rotation thin liquid 61 borrows self weight to flow into silt particle cylinder 1, and Rear end water process is emitted into again rich in the rotation thin liquid after sludge desanding to set.Some fluid material sand 18 are by sludge particle in the inner It is chimeric with sand grains very close, only borrow its resulting finished sand of the single hop cross-flow washed-out sand detached job of single silt particle cylinder 1 21 its clay content are still too high, and
