The invention provides high-efficiency lubricating
oil production and purification equipment. The high-efficiency lubricating
oil production and purification equipment comprises a stirrer, a distiller, a heating sheet, an outer heat preservation shell, a main controller, an oil suction pump, a purifier, a cooling box, a cooling
liquid injection pipe, a cooling liquid
discharge valve, a
waste oil discharge valve, a flow guide
pipe, a lubricating oil eduction
pipe and a
mechanical valve. According to the invention, a
crude oil purification buffer hopper, an inlet pipe and oil outlet pipe, an adsorption sheet and movable bolts, a cleaning plate, an observation window and a
crude oil primary filter screen are arranged, so preliminary
impurity filtering of
crude oil is facilitated, and
distillation effect is ensured; the crude oil is introduced into the crude oil purification buffer hopper through the inlet pipe, impurities are filtered through a crude oil primary filter screen, the filtering condition is observed through the observation window, so that cleaning can be conducted conveniently; meanwhile, iron impurities in crude
oil can be adsorbed in an auxiliary mode through the adsorption sheet, so that the purity of the crude
oil can be guaranteed; impurities in the crude oil primary filter screen and the crude oil purification buffer hopper can be cleaned by loosening the movable bolts and taking down the cleaning plate, the operation is convenient, and the filtering effect is guaranteed.
