Description

Technical Field

[0001] This utility model relates to the field of resistance temperature measurement technology, and in particular to a rapid response temperature measuring device for distiller's grains barrels. Background Technology

[0002] The temperature inside the distiller's grains plays a crucial role in the brewing process. A suitable temperature effectively promotes fermentation, resulting in more ideal fermentation outcomes and significantly improving the taste and quality of the spirit. This is not only important for ensuring product quality but also helps enhance a company's market competitiveness and drives the development of brewing processes towards higher levels of automation and intelligence. Conversely, if temperature monitoring is not timely, it will directly affect the efficiency of alcohol production and the quality of the final product.

[0003] Currently, the response time of temperature measuring devices commonly used in fermentation tanks is typically between 3 and 5 seconds. However, in practical applications, the complex environment of high temperature and humidity inside the tank further slows down the sensor's thermal response speed, resulting in a secondary extension of the effective temperature measurement time. Furthermore, to ensure uniform fermentation, the fermentation tank needs to be frequently turned over with short intervals. Traditional temperature measuring devices used in fermentation containers such as fermentation tanks are mostly non-integrated structures, usually assembled from discrete components: the temperature sensing element is separately installed in a metal protective sleeve, led out through wires, and then manually soldered or crimped to external terminals or connectors; signal transmission relies on long shielded cables connected to a remote data acquisition module. Under these dynamic operating conditions, existing temperature measuring systems are prone to problems such as missing data records, sampling delays, and even signal interruptions, making it difficult to achieve real-time, continuous, and accurate monitoring of temperature changes inside the tank, and failing to capture key temperature information in a timely manner. Summary of the Invention

[0004] This invention provides a rapid response temperature measuring device for distiller's grains barrels to overcome the aforementioned technical problems.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A rapid response temperature measuring device for a distiller's grains barrel includes a housing and a core, wherein the housing and the core are connected to form an integrated temperature measuring structure. The outer casing is composed of a shell, a conversion thread, a protective tube, and a bottom gasket, which are tightly connected from top to bottom. The ferrule is integrated inside the housing and includes a temperature sensor, connecting tube, wires, and a temperature-changing module; One end of the temperature sensor is fixed with a metal back plate; the other end of the temperature sensor passes through a connecting tube and is electrically connected to the temperature change module via a wire; the metal back plate is rigidly fixed to the bottom pad of the housing.

[0006] Furthermore, the connection points of the wires in the ferrule are all fitted with an insulating device; the insulating device is a heat shrink tubing.

[0007] Furthermore, the temperature sensor is a thin-film platinum resistance temperature sensor.

[0008] Furthermore, a temperature-sensing chip is selectively attached to the inner wall of the housing.

[0009] Furthermore, the internal cavity of the protective tube adjacent to the temperature sensor is filled with thermally conductive silicone grease.

[0010] Furthermore, the connecting pipe is a ceramic pipe, and the ceramic pipe has several connecting holes.

[0011] Beneficial Effects: This utility model discloses a rapid-response temperature measuring device for distiller's grains tanks. One end of the temperature sensor is fixed with a metal backplate, and the other end passes through a connecting pipe and is electrically connected to a temperature-changing module via a wire. The metal backplate is rigidly fixed to the bottom pad of the outer casing, significantly improving heat conduction efficiency. This structural design not only greatly shortens the temperature measurement response time and overcomes the problem of sluggish response in the high-temperature and high-humidity environment of traditional devices in distiller's grains tanks, but also ensures the continuity and accuracy of data acquisition under conditions of frequent flipping and short-interval operation.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] This embodiment provides a rapid response temperature measuring device for distiller's grains barrels, such as... Figure 1 and Figure 2 As shown, it includes a housing 16 and a plug 15, wherein the housing 16 and the plug 15 are connected to form an integrated temperature measuring structure; The outer shell 16 is composed of a shell 7, a conversion thread 9, a protective tube 10 and a bottom pad 12, which are tightly connected from top to bottom to form an overall support frame with installation adaptability and mechanical protection function. The insert 15 is integrated inside the housing and includes a temperature sensor 1, a connecting tube 2, a wire 4, and a temperature change module 6; One end of the temperature sensor 1 is fixed with a metal back plate 5; the other end of the temperature sensor 1 passes through the connecting pipe 2 and is electrically connected to the temperature change module 6 via the wire 4; the metal back plate 5 is rigidly fixed to the bottom pad 12 at the bottom of the housing 16 to achieve rapid response.

[0016] In this embodiment, the temperature measuring device is assembled using a combination of laser welding and soft soldering processes to ensure structural stability and signal transmission reliability. Specifically, the protective tube 10 and the base pad 12 are first fixed by laser welding, and then the assembly is laser welded to the conversion thread 9; the lower part of the housing 7 is inserted into the conversion thread 9 by about 2 mm and then firmly connected by laser welding to form an overall rigid support structure.

[0017] In the assembly of the insert 15, the pins of the temperature sensor 1 are first inserted into the connecting tube 2, and then connected to the small end of the stripped wire 4 by laser welding. The large end of the wire 4 is reliably connected to the temperature control module 6 by soft soldering. The wire 4 is preferably made of either perfluoroalkoxy resin (PFA) or polytetrafluoroethylene (PTFE).

[0018] To achieve efficient thermal coupling between the temperature sensor 1 and the bottom of the housing 16, solder wire 13 cut to 2 mm × 2 mm is placed on the base pad 12 inside the housing 16. The metal backplate 5 of the temperature sensor 1 is cleaned with a special cleaning agent and thoroughly dried with compressed air. Solder paste 14 is then evenly applied to its surface and tightly bonded to the solder wire 13 on the base pad 12. The sensing end is heated with a hot air gun for approximately 10 seconds to melt the solder and form a strong connection. It is then rapidly cooled by immersion in water, thus reliably welding the temperature sensor 1 to the base pad 12. After welding, the insert 15 is checked for looseness or detachment, and signal insulation is applied to the relevant electrical connection points.

[0019] Finally, the connection between the end face of the housing 7 and the temperature-changing module 6 is sealed and fixed by laser welding, completing the assembly of the entire temperature measuring device. This process not only ensures the structural integrity and long-term stability of the device under harsh conditions such as high-frequency turning of the fermentation tank and high temperature and humidity, but also significantly improves the thermal response speed and temperature measurement accuracy, effectively meeting the technical requirements for real-time and accurate temperature monitoring during the fermentation process. In this embodiment, the housing 7 and the conversion thread 9 are preferably made of 316L, and the protective tube 10 and the bottom pad 12 are preferably made of either 316Ti or 316L.

[0020] Furthermore, the connection points at both ends of the conductor 4 are insulated; in this embodiment, insulation protection is preferably achieved by covering with heat-shrink tubing 3. The heat-shrink tubing 3 is preferably made of polytetrafluoroethylene (PTFE). Furthermore, in this embodiment, a thin-film platinum resistance temperature sensor is preferentially selected as the temperature sensing element. Resistance temperature detectors (RTDs) are among the most commonly used temperature detectors in the medium- and low-temperature range. Their temperature measurement principle is based on the characteristic that the resistance of a metallic conductor increases with increasing temperature. RTDs have significant advantages such as high measurement accuracy and stable performance. Among them, platinum RTDs have the highest temperature measurement accuracy and are widely used not only in industrial temperature measurement but also as standard reference instruments. RTDs are usually made of pure metal materials, with platinum and copper being the most commonly used. Platinum, due to its excellent chemical stability and linear resistance-temperature characteristics, is particularly preferred in high-precision temperature measurement scenarios.

[0021] Furthermore, this embodiment preferentially uses a temperature conversion module 6 with an integrated M12*1 four-pin connector. This temperature conversion module 6 works in conjunction with a thin-film platinum resistance temperature sensor, converting the temperature signal collected by the sensor into a standard electrical signal in real time and transmitting it stably to the instrument panel or data acquisition device via the M12*1 connector, enabling intuitive temperature display and online monitoring. The selected temperature conversion module 6 has a configurable response time, with a typical setting of 0.33 seconds, ensuring that the response speed of the entire temperature measurement device is controlled within 2 seconds, significantly improving the real-time performance and dynamic tracking capability of temperature measurement, and meeting the high-precision monitoring requirements under rapidly changing conditions in the distiller's grains tank.

[0022] The specific installation and connection methods are as follows: Measuring end (hot end): It is tightly connected to the corresponding threaded interface inside the distiller's grains tank through the process thread, ensuring that the temperature sensing end is accurately inserted into the designated temperature measuring area inside the tank cavity to obtain representative real-time temperature data. Reference end (cold end): Reliably connects to the socket of the external data display device via an M12*1 plug connector to achieve stable signal transmission and quick plugging and unplugging, facilitating maintenance and system integration.

[0023] This design not only improves the reliability and anti-interference capability of the temperature measurement system, but also takes into account the actual needs of industrial sites for rapid installation, sealed protection, and standardized signal transmission.

[0024] Furthermore, a temperature sensing chip 8 can be selectively mounted on the inner wall of the housing 7. In practical applications, when the detected temperature exceeds the range, the temperature sensing chip 8 will change color, thus intuitively indicating to the user whether there is an overheating situation, facilitating maintenance.

[0025] Furthermore, during assembly, solder paste 14 is first evenly applied to the surface of the metal backplate 5. Then, thermal grease 11 is applied to the temperature-sensing end of the insert 15 (i.e., the temperature-measuring part in contact with the slag). Care is taken to ensure that the thermal grease 11 does not come into contact with the metal backplate 5 to avoid affecting the subsequent soldering quality or causing an electrical short circuit. This operation ensures efficient heat conduction between the temperature-sensing end and the measured medium, while maintaining the cleanliness and reliability of the soldering area of ​​the metal backplate 5, thus balancing the temperature measurement response speed and the structural connection strength.

[0026] Furthermore, the connecting tube 2 is made of ceramic, preferably C610, and has several connecting holes. During implementation, the pins of the thin-film platinum resistance temperature sensor are sequentially passed through the corresponding connecting holes of the ceramic tube, then aligned with the small end of the stripped wire 4 and reliably electrically connected using laser welding. This structure utilizes the excellent insulation and high-temperature resistance properties of ceramic materials to effectively isolate electrical interference between pins, while ensuring the long-term stability of the welded joint under high-temperature conditions.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
