[0025] like Figure 1 and Figure 2 The figure shows an intelligent treatment system for starch food processing wastewater, comprising a starch production machine 1, a pump 2, a regulating tank 3, a flocculation tank 4, a sludge tank 5, a sludge pump 6, a screw press 7, and an intermediate water tank 9. The starch production machine 1, regulating tank 3, flocculation tank 4, and intermediate water tank 9 are sequentially connected via the pump 2. The system also includes a medicine tank 8, which is connected to the flocculation tank 4 via a pipeline. A water inlet 402 is provided on the upper side of the flocculation tank 4, and the water outlet of the regulating tank 3 is connected to the water inlet 402 via the corresponding pump 2.

[0026] like Figure 1 、 Figure 2 and Figure 5As shown, the flocculation tank 4 is a tank body with openings at both ends. The upper end of the flocculation tank 4 is provided with a tank cover 401, and the lower end is telescopically inserted into the bottom plate 13. By providing the bottom plate 13, the bottom of the flocculation tank 4 can be opened and closed through the bottom plate 13. The flocculation tank 4 also includes a scraper 406. The inner wall of the flocculation tank 4 is provided with a scraper 406 that abuts against the upper end surface of the bottom plate 13. The scraper 406 is arranged upwardly in the direction of withdrawal of the bottom plate 13. The scraper 406 is abutted against the upper end of the bottom plate 13. When the bottom plate 13 is opened, the scraper 406 can be used to scrape off the sediment on the upper surface of the bottom plate 13 to prevent the sediment from adhering. The lower end of the flocculation tank 4 is located on the upper end of the sludge tank 5. The screw stacker 7 is connected to the sludge tank 5 through the sludge pump 6. By opening the bottom plate 13, the sediment can fall directly into the sludge tank 5, making it convenient to collect the sludge. The pool cover 401 is equipped with a stirring device 10 and a water pump 11 that extend into the flocculation tank 4. The water pump 11 can be raised and lowered, and its upper end is connected to the intermediate water tank 9 via a water pump. The lifting and lowering of the water pump 11 allows it to be lifted during the flocculation process to prevent flocculants from adhering to it in the flocculation tank 4. After flocculation is completed, the settled water in the flocculation tank 4 is pumped out by lowering the water pump 11. The stirring device 10 includes a first motor 1001 and a stirring shaft 1002. The first motor 1001 is mounted on the upper end surface of the pool cover 401. The output shaft of the first motor 1001 extends through the pool cover 401 to the interior of the flocculation tank 4, where the stirring shaft 1002 is located. The water extraction pipe 11 also includes a mounting frame 1101, which is vertically mounted on the upper end surface of the pool cover 401. A screw shaft 1102 is rotatably mounted on the mounting frame 1101, and a second motor 1103 is mounted on the upper end of the screw shaft 1102.

[0027] like Figure 2 and Figure 3As shown, a partition 12 is slidably inserted between the stirring device 10 and the bottom plate 13 on the body of the flocculation tank 4. By providing the partition 12, the sediment in the flocculation tank 4 can be separated from the water in the upper layer, preventing the flocculants from being sucked away during the pumping process of the pumping pipe 11. The flocculation tank 4 also includes a sealing chamber 404. A sealing chamber 404 is provided on the side of the flocculation tank 4 corresponding to the insertion surface of the partition 12. A sealing block 405 is embedded in the sealing chamber 404, and the partition 12 is slidably inserted in the sealing block 405. By providing the sealing chamber 404, the partition 12 can always be in the sealed state of the sealing block 405 when sliding, preventing leakage. At the same time, as the partition 12 slides, it causes the sealing block 405 in the sealing chamber 404 to deform due to resistance. This creates an extrusion force within the sealing chamber 404, improving the sealing effect. Furthermore, an electric telescopic rod 14 is provided. Mounting sleeves 403 are provided on the sides of the flocculation tank 4, corresponding to the height of the partition 12 and the bottom plate 13.

The scraper 406 is arranged upwardly and sloped in the direction of withdrawal from bottom plate 13. The lower end of flocculation tank 4 is located on the upper end of sludge tank 5. A snail stacker 7 is connected to sludge tank 5 via a sludge pump 6. Snail stacker 7 can separate the water content of sludge from the solid-liquid separation of sludge. The separated water can be discharged into intermediate water tank 9 for the next purification process. The pool cover 401 is provided with a stirring device 10 and a water pumping pipe 11 extending to the interior of the flocculation tank 4.

The water suction pipe 11 also includes a mounting frame 1101. The mounting frame 1101 is vertically arranged on the upper end surface of the pool cover 401. A screw shaft 1102 is rotatably arranged on the mounting frame 1101, and a second motor 1103 is arranged on the upper end of the screw shaft 1102; a threaded sleeve 1104 is threadedly sleeved on the screw shaft 1102, and a fixed sleeve 1105 is extended from the side of the threaded sleeve 1104 through the frame body of the mounting frame 1101, and the water suction pipe 11 is installed on the fixed sleeve 1105.

[0030] like Figure 2 and Figure 3 As shown, a partition 12 is slidably inserted between the stirring device 10 and the bottom plate 13 on the body of the flocculation tank 4.

The ends of the partition 12 and the bottom plate 13 extending outside the flocculation tank 4 are fixedly connected to the telescopic ends of the corresponding electric telescopic rod 14.

[0031] The working principle of the present invention is as follows: during operation, the wastewater generated in the starch production machine 1 is put into the regulating tank 3 for water neutralization, and then transported to the flocculation tank 4 for precipitation by adjusting the flocculant. At the same time, the stirring device 10 can be started to accelerate flocculation through the stirring shaft 1002. After the flocculation precipitation is completed, the partition 12 is inserted into the flocculation tank to separate the sediment in the flocculation tank 4 and the upper water, and then the bottom plate 13 is opened. In the process of opening the bottom plate 13, the sediment on the upper end surface of the bottom plate 13 will be cleaned by the scraper 406, and the sediment automatically falls into the sludge tank 5. The sludge in the sludge tank 5 is compressed by the screw stacking machine 7. At the same time, the water above the partition 12 in the flocculation tank 4 will be pumped into the intermediate water tank 9 through the pumping pipe 11 for neutralization and storage, and then the next step of water quality treatment is carried out.

[0032] To sum up, the utility model separates the water and sediment in the flocculation tank 4 by setting a partition 12, and then allows the sediment to automatically fall into the sludge tank 5 by opening the bottom plate 13, without the need for manual cleaning through a scraper, which is simple and convenient; by setting a liftable water pump 11, the water pump 11 can be made to fall off the flocculation tank 4 during the flocculation process, preventing flocs from adhering to the water pump 11.
