Oil residue filtering device for oil pipeline

Abstract

The invention discloses an oil residue filtering device for an oil pipeline. The oil residue filtering device comprises a filter shell and a filter core, wherein the lower end of the filter shell is fixedly connected with a sewage draining exit, the sewage draining exit is in threaded connection with a sewage draining valve, one side of the filter shell is provided with an oil inlet flange, the other end of the filter shell is provided with an oil outlet flange, a cleaning hairbrush is fixedly mounted outside a rotating shaft, the opening end of the filter core is mounted on a mounting plate, the filter core is arranged outside the cleaning hairbrush, a differential pressure transmitter is arranged on the filter core, and is electrically connected with a rotating motor, and an air nozzle is arranged at the lower end of the filter core. By arranging the filter shell, the sewage draining exit, the oil inlet flange, the oil outlet flange, the cleaning hairbrush and the air nozzle, the problems that a traditional cleaning and filtering device is inconvenient to clean, transportation must be stopped during cleaning, and huge economic loss is caused are solved.

Description

technical field [0001] The invention relates to the technical field of pipeline engineering, in particular to an oil residue filter device for oil pipelines. Background technique [0002] The filter is an indispensable device on the conveying medium pipeline. It is usually installed at the inlet end of the pressure reducing valve, pressure relief valve, fixed water level valve, and other equipment of the Fanggong filter. The filter has a filter cartridge of a certain size. Finally, the impurities are blocked. When cleaning is required, just take out the detachable filter cartridge and reinstall it after treatment. Therefore, the use and maintenance are extremely convenient. [0003] However, frequent disassembly of the filter cartridge is not only cumbersome, time-consuming and labor-intensive, but in hot weather, the concentration of volatile oil and gas in the filter is high, and disassembly for a long time may cause poisoning, dizziness, and harm to health. Oil, based on...
