[0024] like Figure 3 , 4 As shown, the slurry mixing and scraping assembly 11 includes a mixing motor 12, a rotating shaft 13, a mixing and scraping rod 14, a slurry processing assembly 15, a rotating and lifting assembly 16 and a linkage hinge rod 17. The mixing motor 12 is arranged on the slurry mixing and lifting assembly 4 and the output shaft of the mixing motor 12 passes through the slurry mixing and lifting assembly 4. The rotating shaft 13 is arranged on the output shaft of the mixing motor 12 and extends into the slurry preparation barrel 1. The mixing and scraping rod 14 is hinged on the rotating shaft 13. The mixing and scraping rod 14 is centrally symmetrically provided with two groups about the rotating shaft 13. The two groups of mixing and scraping rods 14 form an X-shaped arrangement. The slurry processing assembly 15 is arranged on the mixing and scraping rod 14 and is arranged in the slurry preparation barrel 1. The rotating and lifting assembly 16 is sleeved and slid on the rotating shaft 13. The linkage hinge rod 17 is hingedly connected to the rotating and lifting assembly 16 and the mixing and scraping rod 14. The linkage adjustment rocker arm 10 and the rotating and lifting assembly 16 are hingedly connected.
[0025] like Figure 1 , 2 As shown, the slurry mixing and lifting assembly 4 includes a lifting screw 18, a guide rod 19, a lifting motor 20 and a lifting support cover plate 21. The lifting screw 18 rotates on the support plate 3. The guide rod 19 is arranged on the support plate 3 and is symmetrically arranged parallel to the lifting screw 18. The lifting motor 20 is connected to the lifting screw 18. One end of the lifting support cover plate 21 is threadedly connected to the lifting screw 18, and the other end of the lifting support cover plate 21 is slidably arranged with the guide rod 19. The mixing motor 12 is arranged on the lifting support cover plate 21. The lifting support cover plate 21 is provided with a hinge seat 25, and the linkage adjustment rocker arm 10 and the hinge seat 25 are hingedly arranged.
[0026] like Figure 3 , 4 As shown, the slurry processing assembly 15 includes a mixing scraping support rod 22, a dispersing brush 23 and a scraper 24. The mixing scraping support rod 22 is arranged on the mixing scraping support rod 14, the dispersing brush 23 is arranged on the mixing scraping support rod 22, and the scraper 24 is arranged on the mixing scraping support rod 22 and is perpendicular to the direction of the dispersing brush 23. Two groups of scrapers 24 are correspondingly arranged.
[0027] like Figure 4As shown, the rotating lifting assembly 16 is divided into an upper bearing sleeve 26 and a lower rotating member 27. The upper bearing sleeve 26 is slidably sleeved on the circumference of the rotating shaft 13, and the lower rotating member 27 is rotatably connected to the upper bearing sleeve 26. Part of the lower rotating member 27 is arranged between the upper bearing sleeve 26 and the rotating shaft 13.
[0028] During specific use, the catalyst is placed in the slurry preparation barrel 1, and the user starts the lifting motor 20. At this time, the lifting motor 20 drives the lifting screw 18 to rotate on the support plate 3. Under the guiding action of the guide rod 19, the lifting support cover plate 21 slides along the guide rod 19 and drives the height-adjustable mixing component 5 to fall together. At this time, the motor support slider 6 slides in the lifting chute 2, so as to ensure that the height-adjustable mixing component 5 goes deeper into the slurry preparation barrel 1 to disperse and mix the slurry; after adjusting the position, the two groups of mixing scraper rods 14 in the initial state have a small hinged separation distance, and the scraper 24 does not contact the inner wall of the slurry preparation barrel 1. Then the user starts the mixing motor 12, and the mixing motor 12 drives the rotating shaft 13 to rotate, and the mixing scraper rod 14 and the mixing scraper support rod 22 are rotated together in the slurry preparation barrel 1. At this time, the lower rotating member 2 7 rotates on the upper bearing sleeve 26 to achieve the effect of dispersing and mixing the catalyst in the slurry preparation barrel 1. At the same time, the user starts the mixing adjustment motor 7, and the mixing adjustment motor 7 drives the eccentric wheel 8 to rotate, so that the connecting rod 9 rotates eccentrically with the eccentric wheel 8, and pulls the linkage adjustment rocker rod 10 to swing up and down on the hinge seat 25 under the hinge action, thereby pushing the upper bearing sleeve 26 and the lower rotating member 27 to slide up and down on the rotating shaft 13. When the rotating lifting component 16 slides down, under the setting of the linkage hinge rod 17, the two groups of mixing scraping rods 14 are pushed to hinge and unfold in the opposite direction. At this time, the scraper 24 is close to the inner wall of the slurry preparation barrel 1 and swings with the eccentric wheel 8 to achieve a reciprocating action of contacting and separating with the slurry preparation barrel 1, and under the rotation of the rotating shaft 13, the effect of circular scraping of the inner wall of the slurry preparation barrel 1 is achieved, ensuring that the dispersion and mixing is the purpose of not wasting raw materials.
