Embodiment
A kind of twayblade machinery Induced-draft air float machine comprises air-floating apparatus, reflux 7, float skimming device 15, slag discharging device 16 and cell body 13.Air-floating apparatus by motor 1, shaft coupling 2, bearing body 3, main shaft 6, central tube 4, adjustable air suction pipe 5, the diffusion disc 12 that links to each other with the lower end of central tube, and diffusion disc 12 in and form with the affixed impeller mechanism of main shaft 6, this impeller mechanism comprises 6-12 blade 9, lower blade 11 and the impeller dish 10; Blade is the hypsokinesis inclined up and down, and its inclination angle is 25 °-30 °; The aspect ratio of blade is 1.5-1 up and down; In central tube 4, be lower than reflux 7 places and install the sliding surface bearing of making by nylon 8, and be provided with gas in the outside of sliding surface bearing 8-the liquid uniform board, and this gas-liquid uniform board is provided with the hole that diameter is 2mm; Bottom surface is provided with the straight hole that uniform diameter is 2mm on the diffusion disc 12, and diffusion disc 12 outer periphery are provided with uniform wing plate and diameter is the hypsokinesis inclined hole of 2.5-3mm, and the back rake angle of this angling hole is 40 °-45 °.Reflux 7 is made up of return line, valve, governor lever, elbow, tightness system, and vertically inserts the plenum chamber bottom.
Principle of work of the present invention: water body enters plenum chamber through stabilier 14, the impeller dish 10 high speed rotating that motor 1 drive shaft 6 drives in the diffusion disc 12, blade 9 promotes the water body rotation and forms centrifugal force, make and produce vacuum tightness in the diffusion disc chamber, water body and air suck to diffusion disc 12 by the circulation pore on central tube 4 and the diffusion disc 12, air suction pipe 5, reflux 7, and with the form of gas-liquid mixture to around throw away; Simultaneously, lower blade 11 also makes water body produce centrifugal force, the water body of suction its underpart to around dish out.Because lower blade 11 is big than the density of gas-liquid mixture that blade 9 throws away, the movement velocity decay is slower, gas-liquid mixture that blade 9 is dished out produces a kind of additional impellent, and the corresponding vacuum tightness that improves impeller cavity plays auxiliary air-breathing, molten gas effect.In addition, impeller rotation water body replenishes to the center around the water body of its underpart has during by impeller cavity down, forms the water body circulation of impeller bottom.Water-gas mixes after the impeller supercharging is penetrated by the inclined hole on the diffusion disc 12 at negative pressuren zone, produces a large amount of micro-bubbles, and these micro-bubbles hit the further refinement micro-bubble of wing plate in diffusion disc 12 outsides and form air supporting under motive effect.Microbubble climbs up on top of the water adsorbed suspended solid and floats on the surface under bubble supports, and shift exit end by float skimming device 15 onto from the import of cell body 13 in floating-upward process, discharges through slag discharging device 16; Sewage after the purification is through the overflow weir discharging or enter the next stage treatment facility.
The present invention is applicable to that purification separation, suspended solids separation, oily water separation, the flco of sewage separate, the active sludge flco separates, reaches purification coagulating etc.
