The stirring of the medicinal liquid by the stirring rods 14 can conveniently increase the filtration rate of the filter plate 8. When driving the support plate 12 to rotate, compared with the traditional stirring rod 14 which is mainly fixed by welding, the stirring rod 14 is screwed in the threaded hole 13 for subsequent disassembly. The setting of the guide plate 20 can facilitate the pouring of the medicinal liquid into the feed pipe 2 so that the medicinal liquid can be located in the middle part of the filter plate 8.
