Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to a capillary processing device for filtering lubricating oil. Background Art

[0002] At present, the lubricating oil filtration in steel rolling mills mainly adopts the backwashing system. The backwashing system filters the lubricating oil refluxed from the rolling mill into clean oil, and impurities such as particulate matter in the oil remain in the filter tank. When the filtering speed of the filter element decreases, backwashing is performed again, and the dirty oil in the filter tank is blown out by compressed air and enters the dirty oil tank. Then another filter tank is used to filter the dirty oil for a second time, and the relatively clean oil is filtered out and enters the first stage of filtration. The dirty oil remains in a separate dirty oil tank. As a result, the dirty oil generated by the second stage of filtration cannot be processed in time. The static sedimentation method is generally used, and the sedimentation time is generally 2 weeks. After sedimentation, the relatively clean oil on the upper part is pumped into the first stage of filtration, and the precipitated oil residue is treated as waste. The main defects of this method are that the amount of oil residue generated is too large, the oil content is high, and the loss is large. Secondly, the dirty oil is not treated thoroughly, and as time accumulates, it will affect the quality of the oil product. For this reason, a capillary treatment device for lubricating oil filtration is proposed. Utility Model Content
