Description

Technical Field

[0001] The utility model relates to the technical field of cement processing, in particular to a bulk cement multi-stage filtering device. Background Art

[0002] Oil well cement is the main raw material used in oil field cementing. During use, various additives need to be added to the oil well cement according to the conditions of each well to achieve specific performance. This process is called cement dry mixing. Because cement is made by calcining and grinding stones, some cement is often mixed with stones or other impurities when it leaves the factory due to unclean filtration, so it is easy to get stuck in the butterfly valve during mixing. In addition, if the cement is not clean, it is easy to get stuck in the lower ash butterfly valve when the cement truck is pumped, causing the rubber of the cement truck's large pump to be damaged prematurely, and it will cause the cement truck to fill the water poorly, affecting construction safety. The existing bulk cement filter is often a catcher with a filter installed inside. If the filter is too coarse, the filtering effect is not good. If the filter is too fine, it is easy to block the filter. During the ash mixing process or cementing process, the catcher needs to be disassembled continuously, affecting the cement processing efficiency. Utility Model Content

Further, the upper support frame 2 and the lower support frame 1 are connected by the four rigid springs 10, and the two vibration motors 3 are installed on the upper support frame 2, so that the two vibration motors 3 have a better vibration effect on the upper support frame 2, and then better drive the filter container 4 to vibrate, avoiding impurities from adhering to the first filter screen 5 and the second filter screen 6.

[0023] Further, as a preferred embodiment, two vibration motors 3 are installed on the outer walls of the upper support frame 2 on opposite sides. Further, the two vibration motors 3 are installed on the outer walls of the upper support frame 2 on opposite sides, so that the vibration of the upper support frame 2 is more uniform, thereby improving the vibration effect.

[0024] Further, as a preferred embodiment, the diameter of the first filter hole is larger than the diameter of the second filter hole. Further, the diameter of the first filter hole is larger than the diameter of the second filter hole to perform graded filtration on the cement to be filtered and improve the filtration effect.
