A vertically movable mounting plate 3 is provided at the bottom of the top cover 2. Specifically, a vertically extending sleeve 4 is fixedly installed at the bottom of the top cover 2. Four sleeves 4 are arranged in a rectangular array. The upper ends of the sleeves 4 are fixedly installed at the bottom of the top cover 2 by welding or bolts; a movable column 5 corresponding to the sleeve 4 is welded on the top of the mounting plate 3. The movable column 5 extends vertically, and the upper ends of the movable column 5 are vertically slidably installed in the corresponding sleeve 4, thereby guiding the up and down movement of the mounting plate 3; a limit pin 6 arranged vertically therewith is also embedded at the upper end of the movable column 5, and the two ends of the limit pin 6 respectively pass through the outer side of the movable column 5, and the opposite sides of the side wall of the sleeve 4 are respectively provided with strip holes 7 matching the limit pin 6, and the length direction of the strip hole 7 extends vertically, and the two ends of the limit pin 6 are respectively extended into the corresponding strip holes, and the movable column 5 can drive the limit pin 6 to move up and down in the strip hole 7 when it moves up and down along the sleeve 4, and the movable column 5 is prevented from falling off the sleeve 4 downward by setting the limit pin 6.

[0028] like Figure 2 As shown, a vertically extending stirring shaft 8 is rotatably mounted on the bottom of the mounting plate 3 through a bearing. The stirring shaft 8 is coaxially arranged with the tank body 1. A plurality of evenly distributed stirring rods 9 are welded on the stirring shaft 8. The stirring rods 9 extend radially along the stirring shaft 8, thereby improving the stirring effect of the stirring shaft 8.

[0029] like Figure 3 and Figure 4 As shown, a vertically extending central tube 10 is fixedly installed on the top of the mounting plate 3. The central tube 10 is coaxially arranged with the tank body 1. A flange is arranged on the outer edge of the lower end of the central tube 10. The flange is fixedly installed on the top of the mounting plate 3 by bolts. A rotating tube 11 is coaxially rotated and installed on the outer side of the central tube 10 through a bearing. In addition, a baffle 12 is fixedly installed on the central tube 10 above the rotating tube 11 by bolts. The baffle 12 can reduce the risk of the rotating tube 11 falling off. A closed curved groove 13 is arranged on the outer circumference of the rotating tube 11. In this embodiment, the curved groove 13 is arranged around the rotating tube 11 in a wave shape; a vertically extending connecting plate 14 is fixedly installed on the bottom of the top cover 2 by bolts. A sliding pin 15 matching the curved groove 13 is embedded at the lower end of the connecting plate 14. One end of the sliding pin 15 is slidably installed in the curved groove 13.

[0034] In order to prevent the rotating tube 11, the motor 16, the small gear 23, the large gear 24 and other components from being corroded by liquid, a retractable protective cover 25 is connected between the top outer edge of the mounting plate 3 and the bottom of the top cover 2. The protective cover 25 is in the shape of a retractable tube. The upper and lower ends of the protective cover 25 are respectively fixedly connected to the top cover 2 and the mounting plate 3 by bolts. The sleeve 4, the movable column 5, the center tube 10, the rotating tube 11, the motor 16, the small gear 23, the large gear 24 and other components are all located inside the protective cover 25.
