Description

Technical Field

[0001] This utility model relates to the field of biochemical production equipment technology, and more specifically, to a pH control device for a nicotinamide ribose low pH environment production line. Background Technology

[0002] Nicotinamide ribose, as an important bioactive substance, typically requires a low pH environment for its production to maintain reaction stability and product yield. However, existing production lines have several shortcomings in pH control, affecting production efficiency and product quality. Traditional pH detection relies on manual sampling or fixed online monitoring. The former is time-consuming and prone to introducing errors, while the latter lacks dynamic sampling and self-cleaning functions, making sensors susceptible to contamination after long-term use, leading to decreased detection accuracy. Furthermore, conventional pH adjustment methods often have a slow response, making it difficult to achieve rapid and accurate gradient control. Especially under low pH conditions, even small pH fluctuations can lead to product degradation or increased side reactions, affecting the final yield.

[0003] In existing technologies, some automated pH control devices use electromagnetic valves to control sampling, but these are prone to corrosion and failure in highly acidic environments, resulting in a short lifespan. Other rotary detection structures, while capable of intermittent sampling, lack integrated cleaning functions, leading to the accumulation of residual liquid on the inner wall, which can interfere with detection results over time. Furthermore, traditional cleaning methods require shutdown for disassembly or reliance on external flushing systems, increasing operational complexity and potentially causing cross-contamination due to incomplete cleaning. Therefore, to address these technical issues, a pH control device for a nicotinamide ribose low-pH environment production line is proposed. Utility Model Content

The device uses a motor-driven rotating disk to control the opening and closing of the through hole, allowing the liquid in the production line to automatically flow into the detection cylinder. After the liquid level sensor is triggered, the through hole is closed for pH detection. After detection, the original liquid is returned to the pipeline, and an acid or alkali adjusting solution is precisely injected to control the pH value. After the control is completed, the inner wall of the detection cylinder is cleaned by high-pressure water jet to avoid residue affecting subsequent detection, thus achieving efficient, accurate and self-cleaning pH control.

[0029] A limiting ring 9 is fixedly connected to the inner side of the detection cylinder 2, and the rotating disk 7 is slidably connected to the lower surface of the limiting ring 9. The limiting ring 9 can limit the rotation of the rotating disk 7 and improve its sealing performance.

[0030] A first water pump 12 is fixedly connected to the inside of the detection cylinder 2, and a drain pipe 13 is fixedly connected to the outside of the first water pump 12. The end of the drain pipe 13 passes through the detection cylinder 2 and extends into the production line pipeline 1. The cooperation of the first water pump 12 and the drain pipe 13 can realize the rapid backflow of liquid after detection.

[0031] The pH control mechanism includes a first storage tank 14, a second storage tank 15, an infusion pipe 16, and an electric valve 17. The first storage tank 14 and the second storage tank 15 are fixedly connected to both sides of the detection cylinder 2. There are two sets of infusion pipes 16, and each infusion pipe 16 is fixedly connected between the first storage tank 14 and the second storage tank 15 and the production line pipeline 1. The electric valve 17 is fixedly connected to the outside of the two sets of infusion pipes 16. The electric valve 17 can precisely control the injection volume of acid or alkali.

The top of the addition tube 19 is threadedly connected to the threaded cap 20. The design of the addition tube 19 and the threaded cap 20 facilitates the replenishment and sealed storage of liquid.

[0033] The cleaning mechanism includes a hemispherical shell 21, a water outlet 22, a second water pump 23, and a water supply pipe 24. The hemispherical shell 21 is fixedly connected to the inner top of the detection cylinder 2.

[0034] The working principle of the pH control device in the nicotinamide ribose low-pH environment production line based on the embodiment is as follows: When this device controls the pH of the nicotinamide ribose low-pH environment production line, firstly, the drive motor 5 is operated, causing the rotating shaft 6 to drive the rotating disk 7 to rotate, so that the opening 8 is aligned with the through hole 3. This allows the liquid in the production line pipeline 1 to be automatically introduced into the detection cylinder 2 by water pressure. Once the water level is detected by the liquid level sensor 10, the drive motor 5 is rotated again, causing the rotating disk 7 to rotate and control the opening 8 to be misaligned with the through hole 3, thus blocking the through hole 3 and stopping the water inflow. Then, the pH value is detected by the pH monitor 11. After obtaining the gradient that needs to be controlled, the first water pump 12 is operated to discharge the original liquid remaining in the detection cylinder 2 and return it to the production line pipeline 1. Then, depending on the need to adjust the acidity or alkalinity, two sets of electric valves 17 are controlled. A set of systems allows the pH adjustment solution or alkalinity adjustment solution stored in the first storage tank 14 or the second storage tank 15 to be input into the production line pipeline 1 through the infusion pipe 16, thereby enabling rapid adjustment of the pH value of the production line. This is beneficial to the efficiency and effectiveness of the production line products. After the adjustment is completed, the second water pump 23 inside the water storage tank 18 can be operated to introduce clean water from the water storage tank 18 into the internal area of ​​the hemispherical shell 21 through the water infusion pipe 24. By controlling the carrying power of the second water pump 23, the water pressure inside the hemispherical shell 21 can be increased, causing the clean water inside the hemispherical shell 21 to be sprayed outwards at a high water velocity through the water outlet 22 to spray and clean the inner wall of the detection cylinder 2. The water is then discharged into the production line pipeline 1 by the first water pump 12, ensuring the cleanliness of the inside of the detection cylinder 2, effectively improving the accuracy of subsequent detection, and making it easier to adjust the pH of the production line.
