This utility model discloses a device for separating wastewater and organic phase in a nickel sulfate production system. The device includes a storage tank with a drain pipe fixed to the bottom of one side and an empty pipe fixed to the bottom of the other side. Handles are located on both sides of the tank. A water inlet pipe is fixed to the top of a sealing cap. A sealing cap is located at the top of the tank. An overflow pipe is fixed to the other side of the tank. A cleaning assembly is installed inside the tank. This utility model uses an electric telescopic rod to raise and lower a cleaning scraper ring. The raising and lowering of the cleaning scraper ring scrapes away residual dirt on the inner wall of the storage tank, thus cleaning the inner wall. A rotating drive gear drives a toothed groove to rotate a cleaning scraper blade, causing the scraper blade to move on the cleaning scraper ring, scraping away the dirt scraped off the surface of the cleaning scraper ring. The scraped dirt is then discharged through the overflow pipe, ensuring the cleaning effect of the cleaning scraper ring.
