[0002] Crude oil desanding refers to the process of removing sand particles from the oil-water mixture produced from the oil well during oil exploitation. Since crude oil carries sand particles from the formation during exploitation, these sand particles can cause great harm to the system if they enter the ground gathering system. Therefore, crude oil desanding is an indispensable part of petroleum engineering. Common desanding processes include gravity settling method, centrifugal separation method, filtration method and hydrocyclone method, etc. The selection of these processes usually depends on the container type and the sand content of crude oil, aiming to effectively separate sand particles from crude oil to ensure the smooth progress of subsequent processing.

[0003] Current dynamic hydrocyclers are often detachably assembled. This way makes it more convenient to replace the dynamic hydrocyclers when they are damaged. However, the fixing structure of traditional dynamic hydrocyclers is often not flexible enough.
