Liquid lubricating oil filtering device

Abstract

The invention discloses a liquid lubricating oil filtering device. The filtering device comprises a filtering barrel body, a side face oil outlet joint, a first filter screen, an oil outlet elbow, a second filter screen, an oil outlet nozzle, an impurity deposition cone, a waste oil filter screen and a waste oil nozzle, wherein the impurity deposition cone is arranged at the lower end of the filtering barrel body; the side face oil outlet joint is arranged on the lower section side face of the filtering barrel body and positioned above the impurity deposition cone; the first and second filter screens are arranged in an oil outlet pipeline; and the waste oil filter screen is arranged in a waste oil outlet path. Impurity-containing liquid lubricating oil is deposited and filtered by the first and second filter screens and then flows out of the oil outlet nozzle, so that the liquid lubricating oil has low impurity content and can meet the requirement; impurities positioned in the impurity deposition cone can be conveniently discharged; and a pressurizing port is used for making pressure between a barrel cover and the filtering barrel body better facilitate filtering the liquid lubricating oil. The filtering device has the advantages of reasonable structure, difficult blocking of filter screen meshes, high filtering speed and guaranteed filtering quality.

Description

technical field [0001] The invention relates to a liquid oil filter device, in particular to a filter device for liquid lubricating machine oil. Background technique [0002] Liquid lubricating oil has the functions of lubricating friction pairs in mechanical rotation and mechanical sliding mechanisms, reducing frictional resistance, increasing the service life of friction pairs, improving transmission efficiency, and reducing energy consumption. In the actual use process, after the liquid lubricating oil is used for a long time, there will be more and more impurities in it, and it must be replaced regularly. However, the replaced liquid lubricating oil is usually disposed of as waste oil. Although there are also many units that use filtering methods to remove impurities and realize secondary utilization, the existing filtering devices use a filter with a funnel and a filter, which not only has poor filtering effect, but also has a slow filtering speed, and it is very diffi...

Although there are also many units that use filtering methods to remove impurities and realize secondary utilization, the existing filtering devices use a filter with a funnel and a filter, which not only has poor filtering effect, but also has a slow filtering speed, and it is very difficult to use the filter for a long time. It is easy to be blocked by impurities, and a new filter must be replaced every time it is filtered, otherwise it will affect the filtering effect
