[0014] Compared with the prior art, the beneficial effects of this utility model are: the oily wastewater recycling and treatment device not only realizes the function of easy cleaning and enhanced oil removal effect, but also realizes the function of easy disassembly and removal;
[0015] (1) By setting up a filter cylinder, an aeration pump, a filter plate, a connecting slot, a connecting block and a pull ring, oily wastewater needs to pass through the filter cylinder when it enters from the feed port. The filter cylinder can filter flocculent matter and impurities in the wastewater. The aeration pump and the filter plate perform dual treatment filtration of oily wastewater, which enhances the cleaning effect. The filter cylinder can be quickly removed for cleaning.

Due to the different densities, the oil floats on the water surface. When treating, the aeration pump is started. The aeration pump can evenly exhaust air into the interior of the first treatment tank through the first exhaust pipe and the second exhaust pipe. The air flotation method can improve the oil in the water to float on the surface. Most of the floating oil flows into the interior of the oil storage tank along the oil drain pipe for collection. The wastewater containing a small amount of oil can then be treated again through the second treatment tank. This structure realizes the function of facilitating the enhancement of oil removal effect.
[0017] (3) By setting up a mounting base, sealing plate, limiting frame, filter plate, limiting slot and limiting rod, the oily wastewater is treated by the first treatment box and then pumped to the inside of the second treatment box.

[0026] Specifically, such as Figure 1 and Figure 4 As shown, the filter cylinder 6 can filter flocculent matter and impurities in wastewater. The aeration pump 5 and the filter plate 16 perform dual treatment filtration of oily wastewater, enhancing the cleaning effect. The filter cylinder 6 can be quickly removed for cleaning. To clean, hold the pull ring 25 and lift it upwards. The connecting block 24 on the filter cylinder 6 can be removed by moving it out of the connecting slot 23.

The exhaust holes 9 of the second exhaust pipe 18 are located at the top of the pipe.
[0028] Specifically, such as Figure 1 and Figure 2 As shown, oily wastewater enters the interior of the first treatment tank 4 through the inlet 21.

[0031] Working principle: Oily wastewater enters the first treatment tank 4 through inlet 21. Filter cartridge 6 filters flocculent matter and impurities in the wastewater. Due to their different densities, the oil floats on the surface. During treatment, aeration pump 5 is activated. Aeration pump 5 evenly vents air into the first treatment tank 4 through the first exhaust pipe 8 and the second exhaust pipe 18. Through air flotation, the oil in the water floats to the surface. Most of the floating oil flows into the oil storage tank 1 through the oil drain pipe 2 for collection.
