AI Technical Summary
In existing waste oil recovery devices, waste oil tends to solidify during the filtration process, making it difficult to effectively remove impurities and affecting recovery efficiency.
The system uses a combination of heating cylinder and spiral tube for indirect heating to reduce the viscosity of waste engine oil. Combined with a multi-stage filtration system consisting of a filter cylinder, cone filter, and filter sleeve, including a primary cone filter, a secondary cone filter, and a filter sleeve, the system achieves three-stage filtration and impurity removal of waste engine oil through its multi-stage filtration and impurity removal structure.
It effectively reduces the viscosity of waste engine oil, maintains good fluidity, achieves multi-stage filtration of waste engine oil, ensures effective removal of impurities, and improves recycling efficiency.
