[0021] This utility model embodiment provides an online pH monitoring and adjustment device for sweet potato starch production, such as... Figure 1-4As shown, the online pH monitoring and adjustment equipment for sweet potato starch production includes: a pH monitoring sensor 2 installed on the adjustment tank 1 for monitoring the pH value of the sweet potato starch water placed in the adjustment tank 1; a filter box 14 fixedly installed below the adjustment tank 1, the filter box 14 being provided with multiple filter screens 15 for filtering the starch water in the adjustment tank 1 after pH adjustment; an adjustment mechanism installed on the adjustment tank 1 for adjusting the pH value of the sweet potato starch water in the adjustment tank 1; and a stirring mechanism assembled on the adjustment tank 1 for stirring the starch water in the adjustment tank 1.

[0022] In this embodiment, a controller is first installed on one side of the device. The controller can control the entire device. The working principle of the controller is existing technology and will not be described in detail here. During the sweet potato starch production process, starch water is put into the regulating tank 1. The pH value of the starch water can be monitored by the pH value monitoring sensor 2. The pH value monitoring sensor 2 is model HG PH018. When the pH value monitoring sensor 2 detects an abnormal pH value of the starch water, it sends a signal to the controller. The controller receives and recognizes the signal, and then the controller starts the regulating mechanism to add the corresponding acid or alkali solution into the regulating tank 1. At the same time, the controller will start the stirring mechanism to continuously stir the starch water in the regulating tank 1, thereby adjusting the pH value of the starch water and improving the quality of sweet potato starch production. After adjusting the pH value of the sweet potato starch, the starch water in the regulating tank 1 is put into the filter tank 14. The fine impurities in the starch water can be filtered through multiple filter screens 15, thereby reducing the overall complexity of sweet potato starch processing and improving the efficiency of sweet potato starch processing.

[0023] In a further preferred embodiment of this utility model, the adjusting mechanism includes: a first placement box 4 and a second placement box 5 disposed on one side of the adjusting box 1 for placing acid and alkali solutions; a feeding pump 6 assembled on one side of the adjusting box 1, the feeding end of the feeding pump 6 being connected to two feeding pipes 7, the two feeding pipes 7 being respectively connected to the first placement box 4 and the second placement box 5; a bent pipe 8 fixedly installed on the discharge end of the feeding pump 6; and a connecting pipe 9 fixedly installed on the inner wall of the adjusting box 1, the connecting pipe 9 being connected to the bent pipe 8, and the connecting pipe 9 having multiple discharge ports.

[0024] In this embodiment, when the pH monitoring sensor 2 detects that the pH of the starch water is too acidic, the pH monitoring sensor 2 sends a signal to the controller.

The first placement tank 4 contains an alkaline solution. Then the controller activates the feeding pump 6, and the alkaline solution in the first placement tank 4 enters the bent pipe 8 through the feed pipe 7, and then enters the regulating tank 1 through the connecting pipe 9, thereby adding the alkaline solution to the regulating tank 1. Similarly, when the pH monitoring sensor 2 detects that the pH of the starch water is too alkaline, the pH monitoring sensor 2 sends a signal to the controller. The controller receives and recognizes the signal, and then the controller activates the solenoid valve on the feed pipe 7 connected to the second placement tank 5. The second placement tank 5 contains an acidic solution, and then the controller activates the feeding pump 6 to add the acidic solution to the regulating tank 1, thereby adjusting the pH of the sweet potato starch water.

[0028] In this embodiment, when using the stirring mechanism, the first servo motor 11 is started by the controller. With the cooperation of the first synchronous pulley 12 and the first synchronous belt 13, multiple stirring racks 3 are driven to rotate. The rotating stirring racks 3 fully stir and mix the sweet potato starch water and acid and alkali solutions in the regulating tank 1, thereby adjusting the pH value of the sweet potato starch water.

[0029] In a further preferred embodiment of the present invention, the filter box 14 is provided with a discharge mechanism for unloading impurities filtered from the plurality of filter screens 15. The discharge mechanism includes: a plurality of mounting shafts 16 rotatably mounted on the filter box 14, the plurality of mounting shafts 16 being fixedly connected to the plurality of filter screens 15 respectively; a second servo motor 17 fixedly mounted on one side of the outer wall of the filter box 14, the output shaft of the second servo motor 17 being fixedly connected to one end of one of the mounting shafts 16; and a plurality of second synchronous pulleys 18 respectively fixedly sleeved on the plurality of mounting shafts 16, the plurality of second synchronous pulleys 18 being sleeved with a second synchronous belt 19.

[0030] In this embodiment, after the filter screen 15 filters the impurities in the starch water, when it is necessary to unload the filtered impurities on the filter screen 15, the controller starts the second servo motor 17.

[0032] In this embodiment, when it is necessary to filter the starch water in the regulating tank 1 after adjusting the pH value, the pump 20 is started by the controller. The pump 20 draws the starch water in the regulating tank 1 after adjusting the pH value into the filter tank 14. The starch water after adjusting the pH value can be filtered through the filter screen 15. When cleaning the regulating tank 1, the pump 20 is also used to draw water from the regulating tank 1 into the filter tank 14 to clean the impurities filtered on the filter screen 15.
