[0002] The production of potato starch usually includes steps such as cleaning, crushing, starch separation, washing, dehydration and drying. In this process, a large amount of wastewater is generated, mainly from potato washing water and wastewater from starch extraction. These wastewaters contain high concentrations of organic matter, such as starch, protein, amino acids, organic acids, fats, sugars, vitamins, etc., as well as suspended matter, sediment and other impurities;

[0045] Working principle: When the present invention is in use, the potato starch sewage is passed into the two isolation tanks 201 through the sewage inlet pipe 202. At this time, the solid waste in the potato starch sewage entering the isolation tank 201 is blocked by the movable grille 206 located at the bottom of the isolation tank 201. When a large amount of solid waste accumulates on the movable grille 206, the drive motor 602 is started, and the drive shaft 603 is driven to rotate by the drive motor 602, so that the lifting gear 604 rotates with the drive shaft 603. When the lifting gear 604 rotates, the solid waste in the isolation tank 201 is blocked. The lifting gear plate 204 inside the isolation tank 201 rises under the drive of the lifting gear 604, driving the lifting frame 203 connected thereto to rise. At this time, the movable grille 206 with a large amount of solid waste accumulated follows the lifting frame 203 to rise, and the rising lifting frame 203 also drives the baffle plate 207 to rise. When the movable grille 206 rises to the top of the isolation tank 201, the baffle plate 207 blocks the sewage inlet pipe 202, so that the potato starch sewage is stopped from entering the sewage inlet pipe 202, while the lifting frame 203 in the other isolation tank 201 descends and continues to allow the potato starch sewage to enter.

[0046] When the driving shaft 603 rotates, the reciprocating gear 605 is driven to rotate, and the reciprocating box 307 is driven to move toward the lifting frame 203 which rises at the same time through the reciprocating gear 605. Before the movable grille 206 rises to the top of the isolation tank 201, the reciprocating box 307 contacts the movable box 303 at the moving direction end, and the movable box 303 is pushed to move through the reciprocating box 307. At the same time, the discharge gear 310 which rises with the lifting frame 203 is connected with the rack 306, so that the movable box 303 drives the support frame 311 to move at the same time while moving, and drives the rack 306 to move at the same time through the lifting rod 312. When the rack 306 moves, it drives the discharge gear 310 to rotate. When the discharge gear 310 rotates, it drives the movable grille 206 to rotate through the connecting shaft 205. When the movable grille 2 After 06 rotates 180 degrees, the driving motor 602 is controlled to stop. At this time, the movable grille 206 is rotated 180 degrees to facilitate the discharge of solid waste accumulated on the movable grille 206 into the isolation tank 201. When solid waste is being discharged in one isolation tank 201, the sewage inlet pipe 202 in the isolation tank 201 is blocked by the baffle 207, and the lifting frame 203 in the other isolation tank 201 is lowered, so that the sewage inlet pipe 202 in the isolation tank 201 is connected, and then the solid waste in the potato starch sewage is blocked by the movable grille 206, so as to circulate, so that the equipment can continuously block the solid waste in the potato starch sewage and automatically discharge the blocking objects, thereby reducing the manual workload and improving the pretreatment efficiency of the potato starch sewage;

[0047] After being blocked by the movable grille 206, the solid waste enters the filter tank 401, but the sewage still contains small suspended solids. At this time, the sewage is filtered and isolated by the filter layer 402. By starting the water pump 405, the filtered sewage above the filter layer 402 is extracted by the pumping pipe 404, and then discharged into the sedimentation tank 501 through the drain pipe 406. When a large amount of suspended solids accumulate on the filter surface of the filter layer 402, the filter layer 402 is rotated and turned over by turning the handle 403, so as to facilitate backwashing of the filter layer 402 and maintain the filtering effect of the filter layer 402 under long-term use;

[0048] The starch wastewater entering the sedimentation tank 501 is heated by the heating device 502, causing the starch in the wastewater to precipitate. When the reciprocating box 307 moves, the reciprocating plate 506 is driven to move by the reciprocating rod 505, and the connecting plate 507 is driven to move by the reciprocating plate 506. At this time, the scraper 509 is driven to move by the vertical rod 508, and the starch precipitate attached to the heating device 502 is scraped away by the scraper 509 to avoid the starch precipitate being attached to the heating device 502 during long-term heating, making it difficult to remove.
