Detailed Implementation
[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0016] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0017] Example Reference Figures 1-4 This is an embodiment of the present invention, which provides a temperature control structure for an L-tryptophan fermenter, comprising: The temperature control mechanism 100 includes a temperature measuring component 101 and a connecting component 102, and is used to monitor and adjust the internal temperature of the fermenter in real time. The temperature measuring assembly 101 includes a thermometer 1011, an expansion spring 1012, and a temperature measuring column 1013. The thermometer 1011 is used to detect temperature changes. The expansion spring 1012 is connected between the thermometer 1011 and the temperature measuring column 1013 and is used to generate deformation when the temperature changes to drive the temperature measurement signal feedback. The connecting component 102 includes a fixing sleeve 1021, a temperature measuring element 1022, and a fixing rod 1023. The fixing sleeve 1021 is sleeved on the outside of the temperature measuring column 1013. The temperature measuring element 1022 is located between the fixing sleeve 1021 and the temperature control mechanism 100 to enhance the heat transfer efficiency between the temperature measuring component 101 and the temperature control mechanism 100. The fixing rod 1023 is used to fix the temperature measuring component 101 onto the temperature control mechanism 100.
[0018] Specifically, the temperature sensor 1011 is a bimetallic temperature sensor that can generate mechanical deformation when the temperature changes, and drive the temperature measuring column 1013 to move through the expansion spring 1012, so as to realize non-electrical feedback and control of temperature.
[0019] It should be noted that the thermometer 1011 uses a bimetallic temperature sensor, which utilizes the bending deformation of two metal materials with different coefficients of thermal expansion when the temperature changes to drive the expansion spring 1012 to move, thereby driving the temperature measuring column 1013 to move, realizing mechanical temperature feedback without external power supply, and improving the reliability and safety of the system in humid and high-temperature environments.
[0020] Specifically, the expansion spring 1012 is made of a high-temperature resistant and elastically stable material, which can maintain good reset performance under frequent temperature changes, ensuring the continuity and accuracy of temperature measurement feedback.
[0021] It should be noted that the expansion spring 1012 is made of a high-temperature resistant and elastically stable alloy material. During the L-tryptophan fermentation process, it can maintain good elasticity and fatigue life even when exposed to high temperature and high humidity for a long time, ensuring that the temperature measuring component always has accurate response capability and stable reset performance in the face of frequent temperature fluctuations.
[0022] Specifically, the temperature measuring plate 1022 is a metal plate with good thermal conductivity, which is set between the fixed sleeve 1021 and the temperature control mechanism 100, and can improve the response speed of the temperature measuring component 101 to changes in the internal temperature of the fermenter.
[0023] It should be noted that the temperature measuring element 1022 is made of copper or aluminum metal material with excellent thermal conductivity and is set between the fixed sleeve 1021 and the temperature control mechanism 100. It can effectively shorten the heat conduction path between the temperature measuring component 101 and the fermenter body, significantly improve the sensitivity and response speed of temperature detection, and ensure that the temperature control system makes timely adjustments.
[0024] Specifically, the fixing rod 1023 is equipped with a locking structure, which can quickly disassemble and assemble the temperature measuring component 101 by rotation or sliding, making it convenient to replace or maintain the temperature measuring element.
[0025] It should be noted that the locking structure of the fixing rod 1023 can be either threaded or snap-fit, which facilitates quick disassembly and replacement of the temperature measuring component 101 during equipment maintenance or sensor aging without disassembling the entire temperature control mechanism 100, greatly improving the maintainability and ease of use of the device.
[0026] Specifically, a sealing ring is provided between the fixing sleeve 1021 and the temperature measuring column 1013 to prevent liquid or steam inside the fermenter from seeping into the temperature measuring component 101, thus ensuring the stability and service life of the temperature measuring structure.
[0027] It should be noted that the sealing ring between the fixed sleeve 1021 and the temperature measuring column 1013 is made of corrosion-resistant and high-temperature resistant fluororubber or silicone material, which can effectively prevent liquid, steam and corrosive gas inside the fermenter from entering the temperature measuring component, prevent the component from getting damp, corroded or short-circuited, thereby ensuring the long-term stable operation of the temperature measuring structure.
[0028] In use, the temperature control structure of the L-tryptophan fermenter is first installed at the temperature measurement interface of the fermenter. The temperature control mechanism 100 is fixed to the outer wall of the tank or integrated into the control system. The temperature measurement component 101 is stably connected to the temperature control mechanism through the connecting component 102. The temperature measuring column 1013 extends into the fermenter and contacts the medium to sense temperature changes in real time. When the temperature rises or falls during fermentation, the bimetallic temperature sensor used by the temperature sensor 1011 undergoes bending deformation due to the different thermal expansion coefficients of the two metals. This deformation is transmitted and amplified through the expansion spring 1012, causing the temperature measuring column 1013 to undergo axial displacement, forming a non-electric mechanical feedback signal, thereby driving the temperature control mechanism to start the heating or cooling adjustment action. The expansion spring 1012 is made of a high-temperature resistant and elastically stable alloy material. The device is manufactured to maintain good reset performance during frequent temperature cycles, ensuring the continuity and accuracy of temperature measurement response. The temperature measuring plate 1022 is a copper or aluminum metal sheet with high thermal conductivity, which is set between the fixing sleeve 1021 and the temperature control mechanism 100. This effectively improves heat conduction efficiency, accelerates the transmission speed of temperature signals, and enables the control system to respond quickly to temperature fluctuations. The locking structure on the fixing rod 1023, such as threads or buckles, allows for quick installation and removal of the temperature measuring component, facilitating daily maintenance or replacement of sensor elements. At the same time, a sealing ring made of fluororubber or silicone is provided between the fixing sleeve 1021 and the temperature measuring column 1013 to prevent fermentation liquid or vapor from seeping into the temperature measuring component, avoiding component corrosion, short circuits, or measurement inaccuracies, and ensuring long-term stable operation of the equipment in high temperature, high humidity, and highly corrosive environments.
[0029] In summary, by setting up a mechanical temperature sensing assembly consisting of a thermometer 1011, an expansion spring 1012, and a temperature sensing column 1013, stable temperature feedback without external power supply is achieved, improving the reliability of operation in high temperature, high humidity, and corrosive environments. Furthermore, the temperature sensing element 1022 enhances heat conduction efficiency, and the sealing ring effectively prevents fermentation liquid or steam from seeping in, which not only improves the response speed but also ensures the safe operation of internal components.
