For addressing the above problem the technical scheme that the utility model adopts be, cavitation type air floatation machine comprises: casing, aerator, slag scraper, sludge sump and air flotation slot, one side of described casing is provided with water-in, be provided with water outlet at the casing opposite side, described air flotation slot is positioned at a side of casing inner close fitting water-in, and is communicated with water-in; Described sludge sump is positioned at casing near a side of water outlet, and is fixed on casing; Described slag scraper is between aerator and sludge sump; Be provided with return line below air flotation slot, return line one end and air flotation slot internal communication, the return line the other end is positioned at the air flotation slot outside, in casing.
Described aerator is positioned at the top of air flotation slot, and the loose gas impeller of aerator is positioned at air flotation slot.
Described slag scraper comprises dreg scraper, chain, transmission shaft and motor; The two ends of dreg scraper are individually fixed on the chain that is arranged on the transmission shaft both sides, and an end of transmission shaft is connected with motor by scraping the slag step-down gear.
Be provided with the regulation of level plate between described water outlet and sludge sump.
Described bottom half is provided with emptying flange.
Described emptying flange has two, is separately positioned on the both sides of regulation of level plate.
The beneficial effects of the utility model are: the cavitation air flotation trench bottom is established open return line, make its recycle ratio greatly higher than air-dissolving air-float, purification efficiency is also higher than air-dissolving air-float, clearance to grease surpasses 85%, removal to SS surpasses 80%, and the cavitation air flotation trench bottom does not have sludgd deposition.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
Cavitation type air floatation machine comprises: casing 1, aerator 2, slag scraper 3, sludge sump 4 and air flotation slot 5, one side of described casing 1 is provided with water-in 10, be provided with water outlet 11 at casing 1 opposite side, described air flotation slot 5 is positioned at a side of casing 1 inner close fitting water-in 10, and is communicated with water-in 10; Described sludge sump 4 is positioned at casing 1 near a side of water outlet 11, and is fixed on casing 1; Described slag scraper 3 is between aerator 2 and sludge sump 4; Be provided with return line 12 below air flotation slot 5, return line 12 1 ends and air flotation slot 5 internal communication, return line 12 the other ends are positioned at air flotation slot 5 outsides, in casing 1.
Described aerator 2 is positioned at the top of air flotation slot 5, and the loose gas impeller of aerator 2 is positioned at air flotation slot 5.
Described slag scraper 3 comprises dreg scraper 6, chain 7, transmission shaft 8 and motor 9, and the two ends of dreg scraper 6 are individually fixed on the chain 7 that is arranged on transmission shaft 8 both sides, and an end of transmission shaft 8 is connected with motor 9 by scraping the slag step-down gear.
Be provided with regulation of level plate 13 between described water outlet 11 and sludge sump 4.
Described casing 1 bottom is provided with emptying flange 14.
Described emptying flange 14 has two, is separately positioned on the both sides of regulation of level plate 13.
Principle of work is: at first the waste water after coagulating enter the small inflatable section that Cavltation aerator 2 is housed in cavitation air flotation groove 5, waste water fully mixes with " microbubble " of Cavltation aerator 2 generations in inflation section uphill process, Cavltation aerator 2 is the high speed rotating that utilize the loose gas impeller of air delivery pipe bottom, the vacuum that forms in water is with in the input of the air on water surface water, and " microbubble " produces thereupon; Then by loose gas impeller, " microbubble " is evenly distributed in water; The flco absorption that produces through coagulating in " microbubble " and waste water forms the buoyancy aid that whole proportion is significantly smaller than water, forms scum silica frost thereby rely on buoyancy to float up to the water surface; What scum silica frost was interrupted is scraped into sludge sump 4 by bar formula dreg scraper 6; Open return line 12 is established in cavitation air flotation groove 5 bottoms, and return line 12 is by inflating section along air flotation slot 5 bottoms extensions; Cavltation aerator 2 also makes generation negative pressure district, inflation section bottom when producing " microbubble ", make waste water be back to inflation Duan Zaiyu " microbubble " through return line 12 under suction function and meet, and improves pneumatically supported purification rate; Waste water after air-float purification is discharged through overflow groove.
