[0030] By setting up a filtering mechanism, the rotating shaft 23 in a rotating state will drive the cam 24 thereon to cooperate with the filter plate 22 rotating in the filter box 1, so that the filter plate 22 can screen and filter the cell culture medium passing through, and the pure liquid obtained after filtration will be collected in the collection box 26, while the impurities separated during the filtration process will be shaken off by the filter plate 22 and collected in a special waste collection box 27.

The pure liquid obtained after filtration will be collected in the collection box 26, and the filter The impurities separated during the process will be shaken off by the filter plate 22 and collected in a special waste collection box 27. Through this setting, the clogging of the filter plate 22 caused by impurities after filtration can be reduced, thereby improving the filtration efficiency and ensuring the efficient and stable operation of the cell culture medium filtration work; when the waste collection box 27 needs to be cleaned, only the draw plate 291 needs to be pulled upward to open the discharge port 28 on the waste collection box 27, so as to clean out the impurities therein. If the height of the device is adjusted according to the needs of the operator during use, the hydraulic cylinder 38 can be started. The hydraulic cylinder 38 will use the slide rail 35 to make the trapezoidal slider 36 push the guide roller 34 at the bottom of the filter box 1. Since the trapezoidal slider 36 adopts a slope design, in the process of continuously pushing the guide roller 34, the filter box 1 can drive the device thereon to adjust to a suitable height. At the same time, during the lifting process of the filter box 1, the multiple slide bars 33 at the bottom of the filter box 1 will also slide synchronously in the multiple sleeves 32 at the top of the bottom plate 31, so as to ensure that the filter box 1 is more stable during the lifting process.
