Engine oil purifying device for removing volatile contaminants from engine oil

Abstract

The invention relates to an engine oil purifying device for removing volatile contaminants from engine oil, which consists of an evaporating pot, an end cover and a connecting pipe, wherein the evaporating pot is provided with an axial center flow through hole, a by-pass flow through hole and a radial ring groove shaped evaporation chamber; the connecting pipe is coaxially arranged in the center flow through hole; both the connecting pipe and the evaporating pot are provided with micropores for communicating the center flow through hole and the evaporation chamber radially; the evaporating pot is also provided with a pure liquid discharge port communicated with the evaporation chamber; and the end cover is provided with a gas discharge port, wherein the evaporating port is provided with arotary groove shaped evaporation chamber in a run-through mode on one side at the termination end of the ring groove shaped evaporation chamber, and the evaporating pot at the termination end of the rotary groove shaped evaporation chamber is provided with the pure liquid discharge port communicated with the evaporating pot. The engine oil purifying device can be conveniently assembled between a liquid source and a filter of an engine filter system at any angle, and has the purification effect of removing volatile impurities contained in the engine oil efficiently.

Description

technical field [0001] The invention relates to a machine oil purification device, in particular to a machine oil purification device for removing volatile pollutants in machine oil based on the principle of evaporation. Background technique [0002] At present, there are various liquid separation and purification devices based on the principle of evaporation / distillation, which can separate and remove volatile impurities from contaminated liquid by evaporation / distillation. Most of these devices use thin-film evaporation, which means that as the liquid passes over the heated evaporating pan surface, volatile impurities have a boiling point below the surface temperature of the evaporating pan and are separated by evaporation. These devices have been used to purify motor vehicle engine oils. [0003] At present, most of the oil purification devices using the above method are equipped with an independent heating source to maintain the temperature of the evaporator, see US Pat...

AI Technical Summary

Problems solved by technology

However, this kind of oil purification device needs to maintain a horizontal state in the evaporation tank to ensure the smooth formation of a thin film of the internal oil, so as to facilitate the smooth and efficient evaporation / distillation process of volatile pollutants in the oil. Therefore, the installation of the purification device High angle requirements, poor installation adaptability
