Description

Technical Field

[0001] The utility model belongs to the technical field of oilfield mining and filtering, and in particular relates to an oilfield mining oil pollution filtering device which is convenient to clean and maintain. Background Art

[0002] During oilfield extraction, crude oil often carries a large amount of impurities, such as silt, rust, rock particles, and other suspended solids. These impurities not only affect the quality of the crude oil but can also cause serious damage to subsequent processing equipment, reducing its service life and increasing maintenance costs.

[0003] Therefore, in order to solve these problems, it is necessary to use an oil field extraction oil filter device to filter crude oil. The Chinese patent publication number is: CN211328391U (application number: CN201922309595.X) discloses an oil field extraction oil filter device that is easy to clean, including a first box body and a second box body, a motor is provided at the bottom of the second box body, the output end of the motor is connected to the driving shaft, the outer side of the driving shaft is fixedly connected to a first gear, the two first gears are meshed with a second gear, and the second gear The inner ring of the wheel is fixedly connected to a passive rotating shaft, and the end of the passive rotating shaft away from the second gear passes through the first box body and the second box body, a threaded rod is welded to one end of the passive rotating shaft, one end of the threaded rod is connected to the inner ring of the bearing, and a fixing plate is welded to the outer ring of the bearing, a brush rod passes through the outside of the threaded rod, and circular rings are screwed on both sides of the brush rod, and the inner ring of the circular ring passes through the first sliding rod, and a first notch is provided inside the fixing plate, a liquid inlet is provided at the top of the first box body, and a liquid outlet is provided at the bottom of the first box body.
