Vacuum-state centrifugal filtering and dehydrating device for lubricating oil

Abstract

The invention provides a vacuum-state centrifugal filtering and dehydrating device for lubricating oil. An integrated tank is composed of a tank-type vacuum generator and a conduction oil heating device, the tank-type vacuum generator is located above the conduction oil heating device and the tank-type vacuum generator and the conduction oil heating device are separated from each other, an oil tank is connected with an inlet end of the conduction oil heating device through an oil pump, an outlet end of the conduction oil heating device is communicated with a centrifugal filtering device arranged at the upper end of the tank-type vacuum generator, the centrifugal filtering device is communicated with the vacuum generator, the tank-type vacuum generator is internally provided with a conduction oil circulating device communicated with the conduction oil heating device, the top of the tank-type vacuum generator is connected with a vacuum pump through a condenser and a water collection tank, and the bottom of the tank-type vacuum generator is communicated with the oil tank through a high-suction oil drain pump. By adopting the device provided by the invention, moisture in the emulsified oil with the moisture content being 80% can be fully removed; since the temperature control and heat transfer manners are appropriate, the processed lubricating oil is oxidation-free, not black in color and loss-free in additive, the original quality of the oil product can be ensured and thus the vacuum-state centrifugal filtering and dehydrating device has high practical value.

Description

technical field [0001] The invention belongs to the technical field of filtering and purifying devices, and in particular relates to a lubricating oil vacuum state centrifugal filtering and dehydrating device. Background technique [0002] Lubricating oil contains impurities and water, and it must be filtered or purified before use. Traditional lubricating oil filtering or purification devices use liquid jet centrifuges or vacuum oil filters, but the above two methods are There are defects. The jet centrifuge has low filtration accuracy due to the speed limit. The vacuum oil filter cannot filter out the emulsified water in the lubricating oil from the structural principle. Moreover, the above-mentioned equipment is large in size, heavy in weight, and low in working efficiency, resulting in transportation And mobility inconvenience, so it is necessary to improve. Contents of the invention [0003] The technical problem solved by the present invention is to provide a lubric...
