[0002] At present, oil purifiers are filtering devices that use gravity, centrifugal, pressure, vacuum distillation, mass transfer and other technical methods to remove mechanical impurities, oxidation byproducts and water from impure oil. Oil purifiers are mainly used to improve the cleanliness of oil used in machinery and electrical appliances, so that they can play the best performance and extend the service life of the equipment.

[0003] The authorization announcement number in the prior art is: CN209475754U, and the name is a vacuum electrostatic polymerization oil purifier. The application sets a vacuum tank, a condensation tank and an electrostatic polymerization box, and a vacuum pump is set between the vacuum tank and the condensation tank. A coarse filtering device is set on the liquid inlet pipe of the vacuum tank. The dehydration and impurity filtering effects are good, the overall structure is simple, the purified oil has a high purity and good performance. However, the heating method adopted in the application is to heat all the oil with an electric heating plate, improve the heating effect of the oil by stirring, and then evaporate and discharge the water. This heating method is slow. At the same time, when the oil pump injects the oil into the electrostatic polymerization box, the oil enters from the entire oil inlet pipe, and the oil is injected into the electrostatic polymerization box in a columnar shape. The oil is not dispersed enough, which is not conducive to the filter to adsorb the impurity particles in the oil. Utility Model Content
