A compression spring 52 is sleeved on the outer side of the guide rod 3. Both ends of the compression spring 52 are fixed to the bottom side of the lifting frame 4 and the upper side of the fixed plate 51. Vibration motors 53 are installed on the bottom sides of the horizontal planes at both ends of the lifting frame 4. The stirring mechanism 6 includes a rotating shaft 61, a servo motor 62 and a stirring rod 63. The upper side of the inner cavity of the drying cylinder 7 is rotatably connected with the rotating shaft 61. The upper side of the drying cylinder 7 is installed with a servo motor 62 connected to the rotating shaft 61. The left and right ends of the rotating shaft 61 are fixed with stirring rods 63. By setting the vibration mechanism 5, the drying cylinder 7 can be driven to vibrate reciprocatingly up and down through the lifting frame 4. At the same time, the stirring mechanism 6 is used to improve not only the mixing effect of the filtration reducer, but also the drying efficiency is greatly improved.
