[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4 This utility model discloses a sieving device for modified starch production, which includes a base plate 1, a vibration mechanism 2, a filtration mechanism 3, and a drying and stirring mechanism 4. The vibration mechanism 2 includes four springs 27 fixedly mounted on the upper surface of the base plate 1. A fixing plate 22 is fixedly mounted on the upper surface of the four springs 27. An eccentric wheel 25 is mounted in the middle of the upper surface of the base plate 1. The drying and stirring mechanism 4 includes four fixing columns 29 mounted above the fixing plate 22. A first fixing box 9 is fixedly mounted on the top of the four fixing columns 29. A first rotating shaft 13 is rotatably mounted inside the first fixing box 9. Several stirring blades 12 are fixedly mounted in the middle of the first rotating shaft 13. Electric heating tubes 11 are fixedly and evenly distributed inside the inner wall of the first fixing box 9.

[0025] The filtration mechanism 3 includes a second fixed box 31 fixedly disposed in the middle of four fixed columns 29. An inclined filter screen 19 is fixedly disposed in the middle of the inner wall of the second fixed box 31. A second motor 26 is fixedly disposed on the upper surface of the base plate 1. The output end of the second motor 26 is fixedly connected to the second rotating shaft 23. An eccentric wheel 25 is fixedly disposed in the middle of the second rotating shaft 23. A baffle 24 is fixedly disposed on the upper surface of the base plate 1. The other end of the second rotating shaft 23 passes through the baffle 24 and is rotatably connected to the baffle 24. A first fixed block 28 is disposed above the eccentric wheel 25. The first fixed block 28 is fixedly disposed on the lower surface of the fixed plate 22. The second motor 26 drives the second rotating shaft 23 to rotate. The protruding end of the eccentric wheel 25 periodically pushes the first fixed block 28 upward. With the elastic reset of the spring 27, the fixed plate 22 vibrates up and down. When the eccentric wheel 25 rotates and pushes the first fixed block 28, thereby causing the fixed plate 22 to vibrate up and down, the fixed plate 22 drives the second fixed box 31 to vibrate synchronously, causing the inclined filter screen 19 to generate high-frequency vibration, thus preventing starch particles from clogging the filter screen holes.

[0026] A first motor 8 is fixedly installed in the middle of the upper surface of the first fixed box 9. The output end of the first motor 8 is fixedly connected to the first rotating shaft 13. A stirring frame 10 is fixedly installed on the outer surface of both ends of the first rotating shaft 13. The stirring frame 10 is slidably connected to the inner wall of the first fixed box 9. A feed inlet 7 is provided through the upper surface of the first fixed box 9. A first sliding plate 6 is slidably provided through the middle of the feed inlet 7. The contact part between the inner wall of the feed inlet 7 and the first sliding plate 6 is provided with damping. A first connecting pipe 14 is provided through the lower surface of the first fixed box 9. A valve 15 is opened on the surface of the first connecting pipe 14. The stirring blade 12 is a spiral blade, which is responsible for longitudinal stirring of the material. The stirring frame 10 is a ring structure and fits against the inner wall of the first fixed box 9 to scrape off the starch adhering to the box wall and prevent clumping. The two rotate synchronously to achieve all-round stirring and drying.

[0027] The other end of the first connecting pipe 14 penetrates the upper wall of the second fixed box 31, and its outlet corresponds to the high starting position of the inclined filter screen 19, allowing the dried starch to slide and be screened along the inclined direction of the filter screen. A screening outlet 17 is provided on one side of the second fixed box 31, corresponding to the inclined end of the inclined filter screen 19. A second sliding plate 18 is slidably mounted on the upper surface of the screening outlet 17, and the second sliding plate 18 is also equipped with damping. The screening outlet 17 is used to output impurities that are too large to be filtered. A second connecting pipe 20 is installed through the lower surface of the second fixed box 31, and the other end of the second connecting pipe 20 is fixedly connected to the flexible hose 16. The second connecting pipe 20 is used to output starch with a qualified particle size. Two second fixing blocks 30 are fixedly installed on the outer surface of the fixing column 29, and four sliding columns 21 are fixedly installed on the upper surface of the base plate 1. The four sliding columns 21 all pass through the two second fixing blocks 30 and are slidably connected to the second fixing blocks 30. The four sliding columns 21 ensure that the second fixing blocks 30 slide vertically along the sliding columns 21 during vibration, avoiding displacement. The base plate 1 has four positioning holes 5.

[0028] Working principle: In use, the device is fixed in the designated position through the positioning hole 5. The first slide plate 6 is slid open, and the modified starch to be processed is added into the first fixed box 9 through the feed inlet 7. The first slide plate 6 is then closed and fixed in position by its damping structure. The first motor 8 and the electric heating tube 11 are started. The first motor 8 drives the first rotating shaft 13 to rotate, causing the stirring blade 12 and the stirring frame 10 to rotate synchronously, thus stirring the starch in all directions. At the same time, the electric heating tube 11 heats the starch to dry it. The stirring frame 10 can scrape off the starch adhering to the box wall to prevent clumping. After drying, the valve 15 is opened, and the starch enters the second fixed box 31 through the first connecting pipe 14 and falls onto the high end of the inclined filter screen 19. The second motor 26 is started, which drives the second rotating shaft 23 and the eccentric wheel 25 to rotate. This drives the fixed plate 22 to vibrate up and down through the first fixed block 28, causing the second fixed box 31 and the inclined filter screen 19 to vibrate synchronously, accelerating starch screening. Starch with the correct particle size passes through the inclined filter screen 19 and is discharged and collected through the second connecting pipe 20 and the hose 16. Impurities with an excessively large particle size slide along the inclined filter screen 19 to the screening outlet 17, where the second sliding plate 18 can be slid open to discharge and collect the impurities. During vibration, the sliding column 21 cooperates with the second fixed block 30 to ensure vertical vibration of the device and prevent deviation.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
