Description

Technical Field

[0001] The present invention relates to the technical field of oil production, and more particularly to a filtering device for oil production. Background Art

[0002] In the process of oil extraction, impurities are mixed with crude oil. Only some harmful ones such as metals and salts can be removed according to specific circumstances. Therefore, it is necessary to filter the extracted oil. The prior art CN108499192A discloses a filtering device for oil extraction. The filter net is driven to move back and forth by a reciprocating mechanism to vibrate the oil on the filter net, thereby accelerating the speed of oil filtration and improving production efficiency. The filter net can also be disassembled from the reciprocating mechanism to facilitate cleaning of impurities on the filter net, solving the troublesome problem of cleaning the filter net in the past. However, the device still has the disadvantage that due to the simple filtering structure of the device, the filtering effect is poor. At the same time, although the device drives the filter net to move back and forth through the reciprocating mechanism, impurities will still adhere to the filter net, resulting in low filtering efficiency. In view of this, we propose a filtering device for oil extraction. Summary of the invention
