Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
With reference to Fig. 1, the small-sized air-floating apparatus of the one that the utility model provides, comprise be communicated with successively reaction tank 7, dissolved air flotation pond 6 and clean water basin 4, reaction tank 7 is communicated with top, dissolved air flotation pond 6, dissolved air flotation pond 6 is communicated with clean water basin 4 bottom, and reaction tank 7 middle and upper part is provided with the dividing plate 14 reaction tank 7 middle and upper part being divided into left pond 11 and right pond 10, is connected bottom reaction tank 7 with an air dissolved pump 8, top, dissolved air flotation pond 6 is provided with slag scraper 15 and slag-drip opening 1, is provided with mud discharging mouth 5 bottom reaction tank 7.Air dissolved pump 8 is located at the outside of reaction tank 7, and slag-drip opening 1 is located at the side of slag scraper 15, facilitates slag scraper 15 to be scraped by scum silica frost toward slag-drip opening like this, improves the efficiency of deslagging.In use, waste water and the medicament that will add are all enter into bottom reaction tank to react above left pond 11, the last middle and upper part entering into dissolved air flotation pond 6 from top, right pond 10 is separated, scum silica frost flows to slag-drip opening 1 place through the effect of slag scraper 15, and discharged by slag-drip opening 1, some mud that dissolved air flotation pond 6 deposits needs to discharge from mud discharging mouth 5, water through dissolved air flotation pond 6 flows to clean water basin 4, water in clean water basin 4 can be discharged by water outlet, also can be back in reaction tank 7 by return line 10 and again to react.
Dividing plate 14 is highly 1/2 ~ 3/5 of reaction tank 7 height, and dividing plate 14 top is fixed on the top of reaction tank 7.Waste water and medicament can be made can to stop the more time at reaction tank 7 by dividing plate 14, react bottom reaction tank 7 fully, prevent waste water and medicament to be directly discharged into inside dissolved air flotation pond 6, by the effect of medicament.Can also be the structure simplifying whole air-floating apparatus inside by dividing plate 14, reduce cost of manufacture.The height of dividing plate 14 can make corresponding change according to the reaction requirement of reality.
Upper surface, left pond 11 is provided with dosing mouth 13, and the top of left pond 11 sidewall is provided with water-in 12.Can medicament be added by dosing mouth 13, facilitate entering of waste water by water-in 12.
Top, right pond 10 is communicated with dissolved air flotation pond 6.Dividing plate 14 can be coordinated like this to simplify the structure of whole air-floating apparatus inside, reduce cost of manufacture.
Bottom clean water basin 4 outer wall, middle and upper part is provided with water outlet 2, and middle and lower part is provided with the return line 3 be connected with air dissolved pump 8.The water in clean water basin 4 can be discharged by water outlet 2, the water in clean water basin 4 can be back in reaction tank 7 by return line 3 and again react.
The external blast main 9 of air dissolved pump 8, realize air dissolved pump 8 by the air inlet of blast main 9 and produce dissolved air water, blast main 9 is connected with return line 3, can reduce the external hole of air dissolved pump 8 like this, optimizes the structure of air dissolved pump.
In sum, the utility model produces dissolved air water by air dissolved pump, by slag scraper deslagging, and the clear water after deslagging can also be back in reaction zone by air dissolved pump, and reaction tank, dissolved air flotation pond and clean water basin are all use to share pool wall, so both can make simplifying the structure of air-floating apparatus, reduce costs, improve the cost performance that air-floating apparatus uses.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
