[0002] Modified starch is based on the inherent properties of natural starch. In order to improve the performance of starch and expand its application range, physical, chemical or enzymatic treatment is used to introduce new functional groups on the starch molecules or change the size of starch molecules and the properties of starch particles, thereby changing the natural properties of starch and making it more suitable for certain application requirements. In the process of modified starch processing, a large amount of wastewater will be generated, and this wastewater will contain starch particles. If discharged at will, it will pollute the environment.

An auxiliary port 14 is opened on one side of the closing block 11. Automatic unloading is achieved by aligning the auxiliary port 14 with the unloading port 12, and manual unloading by the staff is unnecessary. A unloading port 12 is arranged above the auxiliary port 14, and a feeding port 13 is arranged above the unloading port 12.

[0033] See the attached drawings in the specification Figure 1-4 A protective shell is provided above the device body 1, and the protective shell and the driving motor 3 are installed in an integrated manner. The driving motor 3 and the driving rod 4 are connected by a key connection. The driving motor 3 is protected by the device body 1, which is convenient for subsequent work.

[0034] See the attached drawings in the specification Figure 1-4 The driving rod 4 and the spiral block 9 are connected in parallel. The driving rod 4 and the side rod 8 form an integrated rotating structure. The center point of the spiral block 9 coincides with the center point of the device body 1. The spiral block 9 drives the sludge at the bottom to move upward, thereby ensuring thorough mixing of the sludge.

[0035] See the attached drawings in the specification Figure 1-4 The stirring blocks 7 are evenly and equidistantly distributed on the outside of the side rods 8. The stirring blocks 7 are connected to the side rods 8 by hot melt connection. The side rods 8 are symmetrically distributed on both sides of the driving rod 4. The stirring blocks 7 are driven to rotate by the side rods 8, so that the equipment can operate in an integrated manner.

[0036] See the attached drawings in the specification Figure 1-4The auxiliary rod 10 forms an integrated rotating structure with the driving rod 4 through the connecting belt 5. The auxiliary rod 10 is connected to the device body 1 in a rotating manner. The auxiliary rod 10 and the closing block 11 rotate in an integrated manner.

[0039] Working principle: When using the sewage sedimentation tank for modified starch processing, first, when in use, the sewage to be treated enters the interior of the device body 1 through the water inlet pipe 2, and then the switch of the driving motor 3 is turned on, so that the driving motor 3 drives the driving rod 4 to rotate, and the driving rod 4 drives the spiral block 9 to rotate, and the sludge at the bottom is transferred to the top, and with the rotation of the spiral block 9, the sludge and the precipitant are mixed, and at the same time, the driving rod 4 drives the side rod 8 to rotate through the connecting rod 6, so that the stirring block 7 rotates with the side rod 8, and the sludge on the outside is also driven to rotate and stir together, so as to ensure that the overall sludge and the precipitant are conveniently mixed;

[0040] As mentioned above, when the driving rod 4 rotates, it drives the auxiliary rod 10 to rotate through the connecting belt 5, so that the auxiliary rod 10 drives the closing block 11 above it to rotate, causing the auxiliary port 14 to rotate as the closing block 11 rotates. The auxiliary port 14 overlaps with the discharge port 12 during the rotation process, so that the precipitant inside the feed port 13 above the discharge port 12 automatically falls down. As the driving rod 4 continues to rotate, the auxiliary port 14 continues to overlap with the discharge port 12, realizing small and multiple discharge steps to ensure thorough mixing.

[0041] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
