Scraping and sucking combined type rapid deoiling device for zinc plating wastewater

The invention discloses a scraping and sucking combined type rapid deoiling device for galvanizing wastewater. The scraping and sucking combined type rapid deoiling device comprises an annular wastewater pool, a main shaft, a rotary driving device, a rotary frame, a first lifting driving device, a lifting frame, an outer absorption header, a second lifting driving device, an inner absorption header, a plurality of scraping and sucking assemblies moving in an outer annular cavity and a rotary joint. By arranging the annular wastewater pool, the main shaft and the rotating frame are driven by the rotating driving device to rotate, so that the oil removal range of the scraping and sucking assembly covers the whole outer ring cavity, and the oil removal efficiency can be improved; during oil removal, a large amount of oil in initial wastewater is removed in an oil absorption manner, so that rapid oil removal of a thick oil layer is realized, the oil removal efficiency is improved, finally, oil removal is performe
