This utility model discloses an oil separation device for AKD production, including a processing box, a partition, a quick-release mechanism, filter elements, and a pretreatment mechanism. After the processing box is stabilized by a support frame, a partition is placed horizontally inside. Multiple filter elements are fixed to the top surface of the partition via the quick-release mechanism, arranged sequentially. Each filter element extends below into a clean water chamber below the partition. A wastewater valve is connected to the side wall of the processing box to discharge impurities isolated by the filter elements. A pretreatment mechanism is installed on the processing box; wastewater passes through the pretreatment mechanism to break up the emulsion before entering the processing box. The advantages of this utility model compared to existing technologies are: the pretreatment mechanism breaks down the emulsion structure, making it easier for oil to be retained by the membrane, thus improving processing quality; the quick-release mechanism of the filter elements facilitates replacement, ensuring subsequent processing efficiency while improving subsequent processing effects.
