[0002] Starch saccharification is the process by which starch is decomposed into sweet products by adding water. It is the main process in the manufacturing of starch sugars. During the starch saccharification process, pH adjustment is required. This is usually done by installing an automatic pH adjustment device on the top of the saccharification tank. The existing automatic pH adjustment device is a device that is fixedly installed on the upper surface of the starch saccharification device to automatically adjust the pH. Existing automatic pH adjustment devices, when used for pH adjustment during the starch saccharification process, require the pH electrode to be installed by snapping it into place at the top mounting port, and then securing it again with multiple screws at the top edge using tools. This cumbersome installation process, coupled with the need for repairs after prolonged use and contact with the starch saccharide, necessitates the reverse operation to disassemble the electrode. This makes the disassembly and maintenance of the pH electrode inconvenient and affects the ease of use of the automatic pH adjustment device during the starch saccharification process. Therefore, this invention proposes an automatic pH adjustment device for the starch saccharification process. Utility Model Content

[0003] The purpose of this invention is to provide an automatic pH adjustment device for the starch sugar saccharification process, in order to solve the problem mentioned in the background art where, after the pH electrode is installed at the top mounting port, it is then fixed by rotating multiple screws on the top edge with tools. This makes the installation cumbersome and, after installation, if the pH electrode is damaged due to prolonged use and contact with starch sugar, requiring maintenance, the reverse operation is required to disassemble it, thus making the disassembly and maintenance of the pH electrode inconvenient.

A controller 102 is fixed at the middle position of the front surface of the processing tank 101. The peristaltic pump 104 and the pH electrode 107 are both electrically connected to the controller 102. During the saccharification process inside the processing tank 101, when the pH electrode 107 detects that the internal pH value of the processing tank 101 is too high, the suction tube 105 is connected to the external acid solution. The peristaltic pump 104 works to draw the external acid solution into the processing tank 101 for adjustment. If it is necessary to inject alkali solution, the suction tube 105 is connected to the external alkali solution and injected into the interior through 106 for adjustment. A convenient disassembly and assembly mechanism is provided at the connection between the mounting port 109 and the top edge of the pH electrode 107. A uniform feeding mechanism is provided at the bottom of the inlet 106 at the middle position of the top of the processing tank 101. The convenient disassembly and assembly mechanism includes a clamping component located at the inner edge of the mounting port 109. The bottom end of the clamping component is provided with a limiting sliding component, and the top end of the clamping component is provided with a screw-in and downward moving component. When in use, the pH electrode 107 can be locked inside the mounting port 109. When disassembly and maintenance are required, the convenient disassembly and assembly mechanism can facilitate the disassembly and assembly of the pH electrode 107.

[0016] To facilitate the clamping and fixing of the pH electrode 107 after installation, in this embodiment, preferably, the clamping assembly includes an annular groove 1071 located at the top of the treatment tank 101 at the edge of the mounting port 109. Four outer arc-shaped extrusion plates 1074 are equidistantly arranged at the inner edge of the annular groove 1071, and the end surfaces of the outer arc-shaped extrusion plates 1074 match the surface structure of the pH electrode 107. After the pH electrode 107 is snapped into place, the four outer arc-shaped extrusion plates 1074 can be simultaneously squeezed and moved to clamp the end surfaces of the pH electrode 107, facilitating the fixed installation of the pH electrode 107 and, conversely, facilitating disassembly.

[0017] To facilitate the stable movement and clamping of the outer arc-shaped extrusion plate 1074 via the limiting sliding assembly, in this embodiment, preferably, the limiting sliding assembly includes a sliding groove 1075 formed at the bottom of the annular groove 1071. A sliding block 1077 slides inside the sliding groove 1075. The top end of the sliding block 1077 is fixed to the bottom end of the outer arc-shaped extrusion plate 1074 by screws. The outer arc-shaped extrusion plate 1074 is stably moved and clamped by the sliding block 1077 sliding inside the sliding groove 1075. A return spring 1076 is fixed at the connection between the end of the sliding block 1077 and one end inside the sliding groove 1075. After the extrusion pressure disappears, the return spring 1076 deforms to reset the sliding block 1077 and the outer arc-shaped extrusion plate 1074, facilitating disassembly.

[0018] To facilitate the simultaneous compression and reinforcement installation of the four outer arc-shaped extrusion plates 1074 via the screw-in and downward-moving assembly, in this embodiment, preferably, the screw-in and downward-moving assembly includes an internal thread structure 1073 formed at the inner edge of the annular groove 1071.

An arc-shaped structure 1078 is formed on the inner surface of the bottom end of the external threaded ring 1072. The arc-shaped structure 1078 contacts the surface of the outer arc-shaped extrusion plates 1074. When the external threaded ring 1072 is rotated inside the annular groove 1071 via the internal thread structure 1073, the surface of the arc-shaped structure 1078 contacts the surface of the outer arc-shaped extrusion plates 1074, simultaneously compressing and moving the four outer arc-shaped extrusion plates 1074 for reinforcement installation.

[0019] The uniform feeding mechanism includes a fixed mounting assembly located at the top of the inside of the treatment tank 101 on the outer surface of the agitator 108. A feeding assembly is provided at the connection between the upper surface of the fixed mounting assembly and the bottom end of the inlet 106. A uniform feeding assembly is provided at the inner bottom edge of the fixed mounting assembly. When adding acid for pH adjustment, the uniform feeding mechanism can deliver acid to the middle position inside the treatment tank 101 on the surface of the agitator 108. During mixing, the acid is uniformly delivered to the edge, making pH adjustment more precise.

[0020] In order to facilitate the fixed installation and uniform addition of acid solution by means of a fixed installation component, in this embodiment, preferably, the fixed installation component includes an annular plate 1062 fixedly installed on the top of the processing tank 101 on the outer surface of the stirrer 108 by screws. The annular plate 1062 has a built-in inclined groove 1063 inside, which can allow the acid solution to enter the built-in inclined groove 1063 and fall evenly for processing, so as to facilitate uniform mixing.

[0021] In order to facilitate the entry of externally extracted acid into the interior of the built-in inclined groove 1063 via the feeding assembly, in this embodiment, preferably, the feeding assembly includes a flow channel 1061 located at the bottom of the inlet 106 inside the processing tank 101. The bottom end of the flow channel 1061 is connected to the interior of the built-in inclined groove 1063, and the acid is fed into the interior of the built-in inclined groove 1063 through the flow channel 1061 and falls evenly.

[0022] In order to facilitate the uniform feeding and mixing of the acid solution entering the interior through the uniform feeding component, in this embodiment, preferably, the uniform feeding component includes an annular outlet 1064 formed at the bottom edge of the built-in inclined groove 1063. The edge of the annular outlet 1064 is fixed with a guide plate 1065 by screws. The acid solution entering the interior of the annular plate 1062 can be guided to the bottom through the built-in inclined groove 1063, and then discharged from the annular outlet 1064 and uniformly dropped to the bottom through the guide plate 1065 for mixing.

[0023] In this invention, the peristaltic pump 104 and the pH electrode 107 are both electrically connected to the controller 102, and this electrical connection and control is prior art, which will not be described in detail here.

[0024] The working principle and usage process of this utility model: When using this automatic pH adjustment device for starch saccharification process, firstly, the device is placed stably in the usage position by contacting the bottom end of the processing tank 101 with the ground. After placement, the saccharification liquid is injected into the tank through the feed inlet. After the saccharification liquid is injected into the processing tank 101, the agitator 108 is driven by the reduction motor 103 to rotate inside the processing tank 101 for mixing. Then, during the saccharification process inside the processing tank 101, when the pH electrode 107 detects that the internal pH value of the processing tank 101 is too high, the pipette 105 is connected to the external acid solution, and the peristaltic pump 104 draws the external acid solution into the inlet 106. If it is necessary to inject alkali solution, the pipette 105 is connected to the external alkali solution, which is then injected into the tank from 106 for adjustment. The alkali solution then enters the built-in inclined groove 1063 through the drainage channel 1061, and is discharged from the bottom of the drainage channel 1063 through the annular outlet 1064. The surface of the guide plate 1065 allows the material to fall through to the middle of the saccharified liquid, facilitating even falling. As the agitator 108 rotates to mix the falling acid, it gradually moves the acid from the center to the edge and mixes it until the pH value monitored by the pH electrode 107 reaches a stable value. At this point, the peristaltic pump 104 stops working, thus facilitating even falling and mixing, making pH monitoring more accurate, and improving the convenience and accuracy of the pH automatic adjustment device installed at the top of the treatment tank 101 to regulate the evenly falling acid. Finally, before use, after engaging the top of the pH electrode 107 inside the mounting port 109, hold the external threaded ring 1072 and rotate it inside the annular groove 1071 via the internal thread structure 1073. During rotation, the arc-shaped structure 1078 at the bottom of the external threaded ring 1072 contacts the surface of the outer arc-shaped extrusion plate 1074 and extrudes the outer arc-shaped extrusion plate 1074. The outer arc-shaped extrusion plate 1074 then drives the sliding block 1077 to slide inside the sliding groove 1075, thereby clamping the top of the outer arc-shaped extrusion plate 1074 onto the end surface of the pH electrode 107 for reinforcement. This allows the four outer arc-shaped extrusion plates 1074 to be simultaneously extruded to securely install the pH electrode 107. When the pH electrode 107 is damaged or needs repair after prolonged use, the external threaded ring 1072 can be rotated in the opposite direction to open it, allowing the outer arc-shaped extrusion plates 1074 to be elastically reset for easy disassembly. This improves the convenience of disassembly and maintenance of the automatic pH adjustment device when used at the top of the treatment tank 101.
