Material enters in the current stabilization distributor 8 at top from the top of forward spin flow device 71, and current stabilization is carried out in the current stabilization distributor 8 at top
Afterwards, most of kinetic energy is eliminated, material is from upper strata decanting zone of the cloth hole 801 radially into pond body 1, the fine particle of low concentration
After material continues to settle in upper strata decanting zone, clear water is discharged from the top of pond body 1；And the higher concentration of the inward eddy of forward spin flow device 71 concentration
Material enter the feeding mouth of lower cyclone 72 from the discharging opening of forward spin flow device 71, and carry out in lower cyclone 72 swirl flow
Concentration, obtains the material and high concentration coarse granule material of intermediate concentration granularity, and the material of intermediate concentration is from the top of lower cyclone 72
Portion enters another current stabilization distributor 8, is compressed by the cloth hole 801 of the current stabilization distributor 8 radially into the lower floor of pond body 1
Area, further settle and compress after dehydration, the scraper plate 6 driven through harrow frame 4, which is scraped to the underflow opening 102 of pond body 1, discharges, highly concentrated
Spend coarse granule material then to enter in the current stabilization distributor 8 of bottom of lower cyclone 72, the current stabilization distributor 8 through bottom is directly entered
Bottom discharge area, is directly discharged by underflow opening 102.
It can be seen that, eddy flow twice is carried out by the vertical forward spin flow device 71 being arranged in series up and down and lower cyclone 72 and concentrated, will
Various concentrations, the material of granularity pass through the heavy of the radial discharge of current stabilization distributor 8 positioned at different height to the different height of pond body
Area, compressional zone and bottom discharge area drop.So as to shorten settling height, while improving the treating capacity of thickener, pass through
