[0002] During the process of multiple inversions and long-term transportation, it is difficult to avoid the packaging bags from being damaged, which will cause the cement to become damp and lumpy. During the on-site cement mixing process, the cement blocks will clog the cement filter, greatly increasing the labor intensity of employees. If there are too many cement particles during the construction process, the cement truck's slurry pump will be clogged, causing the oil well cementing construction to fail, leading to downhole technical accidents and causing huge economic losses.

[0003] Publication No. CN203526049U discloses an oil well cement purifier, which drives the screen frame to vibrate through a vibrating motor. Under the action of the vibration force, cement passes through a load-bearing box and is scattered on the screen. Due to the vibration of the screen, the cement is classified. The cement with agglomerates is filtered through the motor vibration and the screen. The cement agglomerates and other impurities are filtered through the inclined screen surface to the debris pool, and the usable cement enters the ground storage tank through the bottom drain for construction use. However, the patent still has the following problems in actual use:

[0004] Although the oil well cement purifier scatters cement on the screen through the load-bearing box and classifies the cement due to the vibration of the screen, the long-term use of the screen is likely to cause the screen to be blocked, affecting its screening effect.
