Claims

[Scope of utility model registration request]

An oil-collecting cylindrical body having an oil inflow opening in the longitudinal direction and equipped with a float and buoyancy adjustment means is installed between both side walls of the treated water tank so that the lower edge of the oil inflow opening is slightly lower than the water surface. an open/close control valve is provided in the oil drain pipe between the oil-collecting cylindrical body and the oil-water separation tank, and between the treated water tank and the oil-water separation tank, A water return pipe with a pump is provided, and an oil recovery pipe with a pump is provided between the oil/water separation tank and the oil recovery tank, and an upper limit liquid level height and a lower limit oil/water interface height in the oil/water separation tank are provided. A liquid level detector is provided to detect the liquid level and the lower limit liquid level height, and when the liquid level height in the oil-water separation tank reaches the set upper limit level, an upper limit liquid level detection signal from the liquid level detector is provided. , the opening/closing control valve is closed, the pump of the water return pipe is operated, and when the height of the oil-water interface in the oil-water separation tank reaches the set lower limit level, the liquid level detector detects In response to the lower limit oil/water interface detection signal, the pump in the water return line is stopped, and the pump in the oil recovery line is operated, so that the liquid level in the oil/water separation tank reaches the set lower limit level. When the liquid level reaches the lower limit liquid level detection signal from the liquid level detector, the pump of the oil recovery pipe is stopped and the opening/closing control valve is opened. Collection and removal device.
