because flotation tank 2 floats on oily sewage, so flotation tank 2 can rise along with the liquid level of oily sewage together, and regulating plate 4 rises along with flotation tank 2 through bracing piece 3 together for the second of regulating plate 4 upper end goes out the high rising of oil groove 401, thereby makes the high rising of the oil-out that first oil groove 101 and second oil groove 401 intercommunication formed. The staff directly operates according to the condition, just can let the greasy dirt that lies in the oily sewage upper strata after the liquid level rises by push pedal 5 from the oil-out push out.
Through the above process, it can be known that:
this embodiment 1 is through setting up oil extraction mechanism, can realize the clearance of floating to the greasy dirt that is located oily upper strata on water. On the one hand, when the liquid level of the oily sewage descends, the oil discharging mechanism can descend along with the liquid level of the oily sewage, so that the height of the oil outlet is reduced, the oil stain on the upper layer of the oily sewage can be cleaned, and the problem that the oil stain cannot be discharged due to the descending of the liquid level of the oily sewage in the background technology is solved.
On the other hand, when oily sewage liquid level rose, because of the oil discharge mechanism can rise along with oily sewage's liquid level together for the height of oil-out rises, so when can clear up the greasy dirt that is located oily sewage upper strata, can also let the regulating plate stop the moisture and discharge, reduce the discharge of moisture, the problem of aggravation moisture discharge because oily sewage liquid level rose among the background art has been solved, greasy dirt exhaust purity has been improved, the work load of carrying out oil-water separation to discharged greasy dirt has been reduced, the treatment effeciency to oily sewage has been improved.
On the other hand, the oil extraction mechanism in this embodiment 1 gradually expands through letting the area that this nine push pedal 5 surrounds on the liquid level of oily sewage, can dwindle the distribution area who is located the greasy dirt on oily sewage upper strata, increases the thickness of greasy dirt, is convenient for discharge from the oil-out the greasy dirt that is located oily sewage upper strata. And, along with the area that these nine push pedal 5 encircleed expands gradually at the liquid level of oily sewage, anticlockwise pivoted displacement has also taken place for push pedal 5, so let the greasy dirt that lies in the push pedal 5 outside also take place anticlockwise whirl, accelerated the flow of greasy dirt to improve the greasy dirt from the speed of oil-out discharge, improved the efficiency of clearance greasy dirt.
Finally, since the area enclosed by the nine push plates 5 is circular, the present embodiment 1 is particularly suitable for use in the can body 1 having a cylindrical structure.
