[0002] Waste oil mostly refers to the oil used for mechanical processing and mechanical transmission. In medium and large processing plants, a large amount of lubrication and heat dissipation oil is used. As the impurities in the oil continue to increase, waste oil is formed. Usually, it is filtered before other recycling work. During filtration, the waste oil tends to become viscous and has poor fluidity at low temperatures, resulting in low filtration efficiency. Impurities retained on the upper part of the filter plate are easy to clog the filter plate, resulting in a slow filtration speed. For this reason, we propose a waste oil recovery and filtration device to solve the above problems. Utility Model Content
