There is a gap between the second grinding filter 14 and the first grinding filter 9; the second connecting piece 15 is a hemispherical structure. Since the grinding efficiency at the center of the second grinding filter 14 is low during the grinding process, the second connecting piece 15 is designed as a hemispherical structure to ensure that the grinding efficiency is high. During the grinding process, a solid base is arranged at the center of the second grinding filter 14, which improves the grinding efficiency; the second grinding rod 16 is a rod-shaped structure; the second brush plate 17 is arranged on the rotating shaft 8, and the second brush plate 17 and the second connecting member 15 sandwich the second grinding filter 14 in the middle, and there is a certain interval between the second brush plate 17 and the second grinding filter 14; a plurality of second brushes 18 are arranged in an array on the second brush plate 17, and each second brush 18 is in contact with the bottom of the second grinding filter 14, which prevents the pores at the bottom of the second grinding filter 14 from being blocked after a long period of grinding.
