[0022] The outer wall of the upper end of the inner cylinder 2 is fixedly sleeved with an annular guide rail, and the outer wall of the annular guide rail is movably sleeved with a rotating circle 9, which is slidably connected to the annular guide rail. The inner wall of the rotating circle 9 is provided with a driven gear ring 10, and the inner wall of the inner cylinder 2 is provided with a transmission mechanism. The transmission mechanism includes a motor 14 and a motor 2 15 symmetrically fixed on the inner wall of the outer cylinder 3. The driving ends of the motor 14 and the motor 2 15 are fixedly sleeved with a driving gear 16 meshing with the driven gear ring 10. After starting the motor 14 and the motor 2 15, the driving gear 16 meshes with the driven gear ring 10 and the rotating circle 9 will rotate along the outer wall of the inner cylinder 2.

[0023] The outer wall of the rotating circle 9 is fixedly sleeved with a shell 11, and the outer wall of the shell 11 is fixedly provided with a spiral plate 12. The outer edge of the spiral plate 12 slides and rubs with the inner wall of the outer cylinder 3, and the inner wall of the outer cylinder 3 is fixedly provided with a scraper 13 located on the upper side of the shell 11.
