Description

Technical Field

[0001] The utility model relates to the technical field of petroleum filtering, in particular to a filtering device for petroleum detection which is easy to disassemble. Background Art

[0002] The oil industry needs to test and analyze crude oil and oil products to ensure that their quality meets relevant standards. Filters play an important role in oil testing. By filtering out impurities such as suspended particles, solid impurities and moisture, clean samples can be provided for subsequent analysis and testing. In the oil testing process, the normal operation and protection of equipment and instruments are essential. Filters can prevent particulate matter from entering the equipment and instruments, reduce the risk of blockage and damage, and extend the service life of the equipment. Oil testing requires accurate test results, and the presence of impurities and contaminants may affect the accuracy of the test. By using filters, impurities that may cause test deviations can be removed, improving the reliability and accuracy of test results.

[0003] Existing oil detection and filtering devices use filter screens and filter elements to filter impurities in oil in layers. After working for a period of time, the impurities in the oil accumulate on the filter screens and filter elements and need to be removed in time. However, the filtering mechanism is generally fixed in the oil connecting pipeline, which is not easy to remove, time-consuming and labor-intensive, resulting in low disassembly and assembly efficiency.
