HGYZD-GY-V grease separation equipment adopts linkage residue lifting technology to lift the residue from the underground oil separator to the above-ground residue collecting barrel, which can effectively intercept solid residues over 6mm. The residue barrel is equipped with a barrel full alarm device. The sewage after solid-liquid separation enters the oil-water separation box through the diversion pipe. By the gravity flow principle of light oil and heavy water, combined with the diversion design of the oil-water separation area, the air flotation device controls the residence time of oil and water in this area and enhances the oil-water separation speed. Separated grease enters the oil collection bin, and is lifted to the ground oil collection barrel by the grease automatic lifting device. The oil barrel is equipped with a barrel full alarm device, so the user only needs to clean the oil and slag barrels regularly. To prevent grease from solidifying and caking, a constant temperature device is installed in the oil collecting tank. Sewage flows into the municipal pipe network or sewage lifting equipment through the anti-siphon outlet pipe. Oil separation and lifting integrated equipment closely combines oil separation and lifting, and centrally controls and manages the two systems. After oil separation, the sewage will be lifted to the pipe network. The buried full-automatic grease separation equipment thoroughly solves the problems of difficult cleaning and maintenance of buried equipment, and realizes the buried full-automatic in the true sense. Advantages of equipment: full-automatic operation, good sealing, automatic slag lifting, automatic oil lifting, air floating heating, convenient installation, accurate liquid level, safety protection, etc.
