Dedicated vacuum oil filtering system for high-viscosity lubricating oil

Abstract

The invention provides a dedicated vacuum oil filtering system for high-viscosity lubricating oil. The dedicated vacuum oil filtering system comprises a vacuum separating device; the vacuum separating device comprises a vacuum tank, an atomizer and a vacuum separator; the atomizer comprises a body and an oil conveying pipe, wherein four groups of atomization channel sets are sequentially arranged in the body from top to the bottom; the vacuum separator comprises a shell and a separating net, wherein the separating net comprises a vertical-horizontal intersected net face and a separating part. The dedicated vacuum oil filtering system has the beneficial effects that oil-water mixture experiences a compression process before entering an atomization channel, the compressed oil-water mixture is suddenly pressed and reduced when leaving the middle of the atomization channel along with enlargement of the cross sectional area, the oil-water mixture is not completely pressed from the atomization channel to the outer wall end of the body, and the oil-water mixture can suddenly scatter in an explosion shape under an effect of vacuum negative pressure after entering the vacuum tank; thus, an oil atomization effect is good, and an oil-water separation effect is good.

Description

technical field [0001] The invention relates to the field of lubricating oil production and processing, in particular to a special vacuum oil filtering system for high-viscosity lubricating oil. Background technique [0002] Vacuum oil filter is designed according to the principle of different boiling points of water and oil. Vacuum oil filter includes primary filter, vacuum heating tank, oil pump, filter device, condenser (condenser) and vacuum pump. The vacuum pump draws the air in the vacuum heating tank from the gas phase outlet of the vacuum heating tank to form a vacuum. Under the action of atmospheric pressure, the external oil passes through the primary filter to remove larger particles, and then enters the heating zone in the vacuum heating tank. The heated oil is separated into a semi-mist by the rapid rotation of the spray wings, and the water in the oil evaporates rapidly into water vapor, and the mixed air is continuously sucked into the condenser by the vacuum ...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the present invention proposes a special vacuum oil filter system for high-viscosity lubricating oil, which solves the difficulty of one-time separation of oil and water in the traditional vacuum oil filter system for high-viscosity lubricating oil, and the impact of airflow on the heat exchange tube and the fan of the strong wind cooling system in the condensation process. The blade makes it cracked and damaged, which affects the heat transfer and cooling effect
