Description

Technical Field

[0001] The utility model relates to the technical field of oilfield chemical additive production, in particular to a high-efficiency filtering device in the oilfield chemical additive production. Background Art

[0002] In recent years, oil fields have mostly adopted chemical flooding to improve crude oil recovery, which has led to increasingly serious scaling problems. In the various processes of oil extraction and refining, a variety of additives need to be used to improve process conditions and increase production efficiency. When using current oil field chemical additives, because the chemical additives themselves are not pure enough and contain fine particles that affect normal use, filtering devices are used to filter them;

[0003] The current filtering device directly filters the oilfield chemical additives through the pipe and the filter screen, which causes the oilfield chemical additives to be in contact with the middle part of the filter screen for filtration. In the long run, the filtering effect of the filter screen will drop sharply, and the filtering effect on the oilfield chemical additives will become worse. Utility Model Content

At this time, the motor 25 can drive the rotating shaft 251 to rotate, and the rotation of the rotating shaft 251 can drive the swing plate 24 to rotate. The push block 23 fixed at the end of the swing plate 24 will push the moving plate 21 to move. When the swing plate 24 rotates continuously with the rotating shaft 251, the push block 23 fixed at the end of the swing plate 24 will continuously move in the movable groove 22 on the moving plate 21, repeatedly in The movable groove 22 moves at the upper and lower ends, and the movable plate 21 is pushed by the push block 23 to move repeatedly left and right. At the same time, the movable plate 21 can drive the processing frame 12 to move repeatedly in the operation box 1 through the connecting block 2. At this time, the filter screen 14 located directly below the lower hopper will move back and forth continuously, so that the falling chemical additives all contact different positions of the filter screen 14, thereby preventing the filter screen 14 from being excessively blocked and affecting its service life due to falling only at the middle position of the filter screen 14, thereby improving the filtration service life of the filter screen 14 and ensuring the efficient filtration effect of the chemical additives of the filter screen 14.
