The driven gear 8 is mounted on the rotating shaft 4, and the driving gear 7 and driven gear 8 mesh with each other. The motor 6 drives the rotating shaft 4 to rotate, thereby causing the rotating cage 3 to rotate. The liquid extraction mechanism includes a transfer pump 9, a collection tank 10, an input pipe 11, and an output pipe 12. The input end of the transfer pump 9 is connected to the rotary joint 5 through the input pipe 11, and the output end of the transfer pump 9 is connected to the collection tank 10 through the output pipe 12.
