Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5This utility model provides an embodiment of a starch separation device for sweet potato flour production, including a support block 1 and an mounting plate 21 installed on top of the support block 1. A motor 22 is connected to the top of the mounting plate 21. A threaded post 23 is connected to the output end of the motor 22. A rotating ring 24 is threadedly connected to the outer end of the threaded post 23. A retaining ring 25 is connected to the front end of the rotating ring 24. A connecting block 26 is connected to the front end of the rotating ring 24. Four grooves 27 and four slots 214 are formed on the outer end of the connecting block 26. A connecting ring 28 is movably connected to the outer end of the connecting block 26. Four retaining posts 29 are installed inside the connecting ring 28 and are movably connected to the slots 214. Four holes 210 are formed inside the connecting ring 28. Ball bearings 211 are movably connected inside the holes 210. A connecting block 212 is installed at the front end of the connecting ring 28. A screen 213 is connected to the front end of the connecting block 212. The connecting ring 28 is sleeved with the connecting block 26, allowing the retaining post 29 to insert into the retaining groove 214 and the ball 211 in the hole 210 to fit against the groove 27. Rotating the rotating ring 24 drives the retaining ring 25 to move, and the retaining ring 25 blocks the hole 210 to restrict the position of the ball 211. By setting up multiple components such as the motor 22, threaded post 23, rotating ring 24, retaining ring 25, connecting block 26, connecting ring 28 and connecting block 212 in coordination, the screen 213 can be quickly assembled and disassembled. For easy replacement and cleaning, during installation, the connecting ring 28 is sleeved with the connecting block 26, allowing the locking post 29 to be inserted into the locking groove 214 for initial positioning. The ball bearing 211 fits into the groove 27. Rotating the rotating ring 24 moves the rotating ring 24 forward, causing the locking ring 25 to block the hole 210 and restrict the ball bearing 211, thus completing the fixing of the screen 213. Disassembly is performed by reversing the operation. No complicated tools are required; disassembly and assembly can be completed quickly through mechanical linkage, facilitating timely cleaning or replacement of the screen 213 and reducing maintenance time.

[0022] Please see Figure 2-5 A further solution based on this embodiment is as follows: the front end of the support block 1 is connected to the outer shell 31, the rear side of the inner side of the outer shell 31 is connected to the partition 32, the partition 32 is provided with a rotating shaft, the partition 32 is movably connected to the connecting block 212 through the rotating shaft, the outer shell 31 forms a closed working space to prevent starch and water from splashing and polluting the environment, the partition 32 enhances the structural stability of the outer shell 31, and the rotating shaft provides rotational support for the connecting block 212 (and the screen 213), ensuring that the screen 213 can rotate stably to achieve centrifugal separation, and providing a structural basis for subsequent solid-liquid separation.

[0023] Please see Figure 1-5A further solution based on this embodiment is as follows: a drainage groove 33 is provided at the bottom of the outer shell 31, and a water outlet pipe 34 is connected to the left end of the outer shell 31. The water outlet pipe 34 is connected to an external pipe. The drainage groove 33 collects the water thrown out by the screen 213 to prevent water accumulation inside the outer shell 31. The water outlet pipe 34 quickly discharges the separated water to the external pipe to achieve orderly discharge of wastewater, keep the inside of the device dry, and reduce the impact of residual moisture on starch quality.

[0024] Please see Figure 1-5 A further solution based on this embodiment is as follows: the water outlet pipe 34 is connected to the drainage trough 33, and the front end of the outer shell 31 is provided with a movable groove 35. The collection frame 36 is movably connected inside the movable groove 35. The water outlet pipe 34 is connected to the drainage trough 33 to ensure smooth water flow and improve drainage efficiency. The movable groove 35 provides an installation track for the collection frame 36. The collection frame 36 can accurately receive the separated sweet potato starch, realize the centralized collection of starch, avoid scattering and waste, and improve the convenience of collection.

[0025] Please see Figure 1-5 A further solution based on this embodiment is as follows: a handle 37 is connected to the front end of the collection frame 36, a cover plate 38 is rotatably connected to the front end of the outer shell 31, and a conical block 39 is connected to the rear end of the cover plate 38. The handle 37 facilitates the operator to quickly pull the collection frame 36, improving the efficiency of picking up and putting away starch. The cover plate 38 can close the front end of the outer shell 31 to prevent starch from splashing during the separation process. The conical block 39 optimizes the internal space structure, guides the starch to concentrate in the collection frame 36, and reduces residue.

[0026] Please see Figure 1-5 A further solution based on this embodiment is as follows: the inside of the conical block 39 is connected to a feed pipe 310, which is connected to an external pipe. The feed pipe 310 realizes the stable transportation of raw materials (sweet potato slurry). The connection with the external pipe can be adapted to a continuous production line. The conical structure of the conical block 39 makes the slurry evenly dispersed into the device, avoids local accumulation, ensures that the screen 213 is evenly stressed, and improves the separation effect.

[0027] Please see Figure 1-5 A further solution based on this embodiment is as follows: the screen 213 rotates to throw out water, allowing the water to flow into the drainage trough 33 and be discharged through the water outlet pipe 34. The separated sweet potato starch is thrown out through the screen 213 and guided into the collection frame 36 in the movable trough 35 through the outer shell 31. The collection frame 36 is pulled out by pulling the handle 37, forming a complete closed loop of centrifugal separation-water discharge-starch collection. The rotation of the screen 213 achieves efficient solid-liquid separation, the outer shell 31 guides the material flow to avoid waste, and the collection frame 36 cooperates with the handle 37 to achieve rapid starch extraction. The whole process is smooth and continuous, greatly improving production efficiency and starch recovery rate.

[0028] Working principle: Before starting the device, insert the locking pin 29 in the connecting block 212 into the locking groove 214, so that the ball 211 in the hole 210 enters the groove 27. Then rotate the rotating ring 24, which rotates on the threaded pin 23, causing the rotating ring 24 to move forward and push the locking ring 25 to block the hole 210 of the connecting ring 28, restricting the position of the ball 211. With the locking pin 29 and the locking groove 214 engaged, the screen 213 connected to the connecting block 212 is quickly fixed on the rotating shaft of the partition plate 32, completing the assembly. During production, the raw material is conveyed to the conical block 39 through the feed pipe 310, and evenly dispersed into the screen 213 through the conical structure. The motor 22 drives the screen 213 to rotate at high speed, generating centrifugal force, which... Water is ejected from the sweet potato slurry and flows along the inner wall of the outer shell 31 into the bottom drainage trough 33. It is then discharged through the water outlet pipe 34 and the external pipe, achieving solid-liquid separation. The separated sweet potato starch is ejected by the screen 213 and falls into the collection frame 36 in the movable trough 35 under the guidance of the outer shell 31 and the cone block 39. After production, the rotating ring 24 is rotated in reverse to move it backward, and the retaining ring 25 releases the restriction on the ball bearing 211. The screen 213 can be quickly disassembled for cleaning and replacement. The starch can be taken out by pulling the handle 37 of the collection frame 36. The cover plate 38 can close the outer shell 31 during production to prevent starch from splashing. The entire process realizes continuous production from raw material input to finished product collection, greatly improving efficiency.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
