[0024] See also Figure 2-5As shown, a stirring motor 12 is installed on the top side of the stirring barrel 1, a rotating shaft 13 is installed on the output end of the stirring motor 12, a spiral blade 14 is installed on the outer wall of the bottom end of the rotating shaft 13, two stirring rods 15 are symmetrically installed on the outer wall of the middle end of the rotating shaft 13, mounting rings 16 are installed on the outer walls of both ends of the rotating shaft 13, sleeves 17 are installed on the outer walls of the mounting rings 16, a return spring 18 is installed on the inner wall of the sleeve 17, one end of the return spring 18 is fixedly connected to a movable rod 19, and one end of the movable rod 19 is connected to a scraper 20; when working, the starch slurry is a slurry in an immature and uncured state after the starch is mixed with liquids such as water without heating or other treatments, Therefore, a stirring device is needed. The stirring motor 12 is started to drive the rotating shaft 13 to rotate. The rotating shaft 13 drives the spiral blade 14 to rotate. The spiral blade 14 stirs and pushes the raw slurry in the up and down directions to promote the overall mixing and circulation of the raw slurry. At the same time, the stirring rod 15 stirs the raw slurry in the horizontal direction as the rotating shaft 13 rotates, further enhancing the stirring effect. At the same time, the mounting ring 16 drives the sleeve 17 to rotate accordingly, and the return spring 18 gives the movable rod 19 an outward thrust, so that the scraper 20 is always in close contact with the inner wall of the mixing barrel 1, so that the scraper 20 can continuously scrape off the material that can be attached to the inner wall of the mixing barrel 1 to prevent the material from accumulating on the barrel wall and affecting the stirring quality, while keeping the inner wall of the mixing barrel 1 clean.

[0025] See also Figure 2 , 4 As shown in Figure 5, a box body 21 is fixedly connected to the outer wall of the mixing barrel 1, and fixed rods 22 are fixedly installed at the four corners of the bottom side of the box body 21.

After the stirring is completed, the valve 26 on the discharge pipe 25 is opened, and the stirred raw starch slurry flows out from the stirring barrel 1 through the discharge pipe 25. When the raw starch slurry flows to the filter plate 23, due to the effect of gravity, pressure is generated on the filter plate 23, causing the filter plate 23 to slide downward on the fixed rod 22, and the compression spring 24 is compressed. In this process, the filter plate 23 will filter the raw starch slurry and intercept large particles that have not been fully stirred.

[0026] Working principle: start the driving motor 10, drive the connecting rod 11 to rotate, and then drive the slider 8 to slide up and down in the hollow plate 7, so that the slide plate 5 will slide back and forth in the horizontal direction in the slide groove 4. When the feed port 6 and the feed pipe 2 are completely overlapped, the material can smoothly enter the mixing barrel 1 from the feed hopper 3 through the feed pipe 2. At this time, it is in the feeding state. When the slide plate 5 slides to make the feed port 6 and the feed pipe 2 staggered, the feeding speed gradually decreases to stop feeding, so that the material is intermittently added to the inside of the mixing barrel 1, avoiding uneven stirring caused by excessive feeding, and improving the stirring efficiency and stirring quality;

[0027] The stirring motor 12 is started to drive the rotating shaft 13 to rotate, and the rotating shaft 13 drives the spiral blade 14 to rotate. The spiral blade 14 stirs and pushes the raw pulp in the up and down directions to promote the overall mixing and circulation of the raw pulp. At the same time, the stirring rod 15 stirs the raw pulp in the horizontal direction as the rotating shaft 13 rotates, further enhancing the stirring effect. At the same time, the mounting ring 16 drives the sleeve 17 to rotate accordingly, and the return spring 18 gives the movable rod 19 an outward thrust, so that the scraper 20 is always closely fitted with the inner wall of the mixing barrel 1, so that the scraper 20 can continuously scrape off the materials that can be attached to the inner wall of the mixing barrel 1, prevent the materials from accumulating on the barrel wall and affecting the stirring quality, and keep the inner wall of the mixing barrel 1 clean;

[0028] After the stirring is completed, the valve 26 on the discharge pipe 25 is opened, and the stirred raw starch slurry flows out from the stirring barrel 1 through the discharge pipe 25. When the raw starch slurry flows onto the filter plate 23, due to the effect of gravity, pressure is generated on the filter plate 23, causing the filter plate 23 to slide downward on the fixed rod 22, and the compression spring 24 is compressed. In this process, the filter plate 23 will filter the raw starch slurry and intercept large particles that are not fully stirred. The filtered raw starch slurry continues to flow downward and is finally discharged from the discharge pipe 27 on the side of the box body 21.
