Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of biological fermentation equipment, in particular to a circulating heat dissipation system for intelligent temperature control of a fermentation tank. BACKGROUND

[0002] In terms of heat dissipation, traditional fermentation tanks mainly rely on natural heat dissipation or simple air cooling and water cooling. However, these methods are often insufficient when facing a large amount of heat generated during fermentation. The heat dissipation efficiency is extremely low. When the heat cannot be dissipated in time and effectively, the temperature in the tank will continue to rise, quickly exceeding the temperature range suitable for the growth of microorganisms, thereby inhibiting the activity of microorganisms and greatly reducing the fermentation efficiency. In extreme cases, fermentation may even fail completely. More importantly, the traditional heat dissipation method lacks the ability to flexibly adjust according to the actual heat generation during fermentation, making it difficult to meet the differentiated needs of different fermentation stages.

[0003] Patent Publication No. CN220855530U, a fermentation tank intelligent temperature control system, includes a temperature control assembly, which includes a refrigeration water tank, a tank body, a support column, an inner tank, a groove, a heating plate, a heat dissipation pipe, a temperature sensor, a PLC controller, a water pump, and a connecting pipe. The utility model detects the temperature inside the inner tank in real time through the temperature sensor and transmits the detected temperature signal to the PLC controller. When the temperature data received by the PLC controller is lower than its preset value range, the PLC controller turns on the heating plate to heat the inside of the inner tank. When the received temperature data is higher than its preset value range, the PLC controller turns off the heating plate and starts the water pump. The water pump draws cold water from the refrigeration water tank through the connecting pipe and sends the cold water to the heat dissipation pipe to dissipate heat from the inner tank. The cold water enters the refrigeration water tank again through the other end of the heat dissipation pipe to cool down. The utility model effectively ensures that the materials inside the inner tank can be kept at an appropriate temperature, improving the fermentation effect.

[0004] In view of the related technology in the above, the inventors found that the above-mentioned device has the following defects: the temperature control precision is insufficient: indirect temperature control by a single heating plate or water cooling pipe makes it difficult to achieve precise temperature regulation in different areas of the fermentation tank, which may cause local overheating or overcooling due to heat conduction lag, affecting the activity of microorganisms; the water pump is used to extract cold water for circulation, but the water flow speed and temperature gradient are not well matched, the heat dissipation rate is low in high-temperature areas, and it is difficult to cool down quickly during the peak period of fermentation heat production; the heating plate and water pump are frequently started and stopped, and the water cooling system needs to continuously run the refrigeration water tank, resulting in low energy utilization rate.

[0025] The circulating heat dissipation assembly 3 further comprises a servo motor 301, a magnetic coupler 302, a stirring shaft 303, a sealing ring 304, a liquid injection pipe 306, a liquid outlet pipe 307, a stirring short rod 308 and a stirring long rod 309; the servo motor 301 is fixedly installed on the top of the support 1, and the output end thereof is connected with the stirring shaft 303 through the magnetic coupler 302; the stirring shaft 303 penetrates through the top of the fermentation tank body 305 and is sealed through the sealing ring 304, and a plurality of stirring short rods 308 are arranged on one side of the stirring shaft 303, and the stirring long rod 309 is fixedly installed at the bottom; the liquid injection pipe 306 and the liquid outlet pipe 307 are fixedly installed on the top and the bottom of the outer wall of the fermentation tank body 305 respectively.

[0026] The stirring short rods 308 are located between the clearances between adjacent heating discs 311, and the length of the stirring short rods 308 is smaller than the minimum distance between the adapter pipes 312 and the stirring shaft 303.

[0027] The first temperature control electromagnetic valve 313 and the second temperature control electromagnetic valve 314 are both provided with a one-way valve for controlling the one-way flow of the heat conducting oil; the heating discs 311, the adapter pipes 312, the first circulating pipe 315 and the second circulating pipe 318 are filled with the heat conducting oil, and the heat conducting oil flows along the closed path under the driving of the circulating pump 317.

[0029] The control cabinet 2 is provided with a temperature control module, and the temperature control module is signal connected with the first temperature control electromagnetic valve 313, the second temperature control electromagnetic valve 314 and the circulating pump 317 through a temperature sensor, for dynamically adjusting the flow rate and the heat exchange intensity of the heat conducting oil according to the internal temperature of the fermentation tank body 305.

[0030] It needs to be further explained that:

[0031] The first temperature control electromagnetic valve 313 and the second temperature control electromagnetic valve 314 in the circulating heat dissipation assembly 3 are provided with one-way valves, which ensure that the heat conducting oil can only flow in one direction, and they work cooperatively with the temperature control module in the control cabinet 2 to accurately control the in and out of the heat conducting oil according to the real-time change of the internal temperature of the fermentation tank body 305; the heating disc 311 is composed of multiple circular annular hollow discs and is connected through the adapter pipes 312 arranged in a staggered manner, and this unique structure makes the heat conducting oil uniformly distributed in the heating disc 311, so as to uniformly heat the materials in the fermentation tank; when the temperature is too high, the temperature control electromagnetic valves 313 and 314 timely adjust the flow of the heat conducting oil, and at the same time, the heat exchanger 316 cooperates with the heating disc 311 to dissipate heat or appropriately heat the heat conducting oil, so as to ensure that the temperature in the fermentation tank always maintains in the accurate interval suitable for fermentation.

[0032] The servo motor 301 is connected with the stirring shaft 303 through the magnetic coupler 302, and can effectively realize sealing and isolation while providing strong power, so as to prevent the leakage of the material in the fermentation tank. The stirring shaft 303 penetrates the top of the fermentation tank and is sealed through the sealing ring 304, so as to ensure the sealing of the equipment. The stirring short rod 308 and the stirring long rod 309 on the shaft cooperate with each other, the stirring long rod 309 stirs the material in the tank in a large range, so that the material is fully mixed and the precipitation or caking phenomenon is avoided, and the stirring short rod 308 is ingeniously located between the clearances of the adjacent heating discs 311. The length of the stirring short rod 308 is carefully designed to be smaller than the minimum distance between the adapter pipe 312 and the stirring shaft 303. In the process of stirring the material, the stirring short rod 308 can effectively assist the heat transfer between the heat conducting oil and the material, further improve the uniformity of heat distribution, and strengthen the temperature control effect, so as to provide a more optimal material environment for the fermentation process.

[0033] The working principle of the above embodiment is as follows:

[0034] Firstly, the temperature control module in the control cabinet 2 monitors the temperature data in the fermentation tank body 305 in real time through the temperature sensors. The temperature sensors are distributed at key positions of the fermentation tank, can accurately capture the temperature change, and rapidly transmit the collected temperature signal to the temperature control module in the control cabinet 2.

[0035] Secondly, when the temperature control module determines that the temperature in the fermentation tank needs to be adjusted, the circulating pump 317 starts to work. As the power core of the entire heat conducting oil circulation system, the circulating pump 317 drives the heat conducting oil filled in the heating disc 311, the adapter pipe 312, the first circulation pipe 315 and the second circulation pipe 318 to start to flow. The heat conducting oil flows out from the second temperature control electromagnetic valve 314, passes through the first circulation pipe 315 and the heat exchanger 316 in turn. In this process, the heat exchanger 316 preliminarily processes the heat conducting oil according to the temperature condition. Then, the heat conducting oil is pressurized by the circulating pump 317 and flows to the first temperature control electromagnetic valve 313 through the second circulation pipe 318, so as to build a closed heat conducting oil circulation channel and prepare for heat transfer.

[0036] Then, if the temperature in the fermentation tank is lower than the preset value, the temperature control module issues an instruction, and the first temperature control electromagnetic valve 313 is opened. The heat conducting oil flows into the heating disc 311. The unique staggered adapter pipe 312 connection structure of the heating disc 311 enables the heat conducting oil to be uniformly distributed in the multi-layer hollow disc. As the heat conducting oil circulates in the heating disc 311, the heat carried by the heat conducting oil is transferred to the material in the fermentation tank through the metal wall of the heating disc, so as to uniformly heat the material and gradually increase the temperature in the fermentation tank.

[0037] Next, in the temperature regulation process, the servo motor 301 starts to work, the servo motor 301 is connected with the stirring shaft 303 through the magnetic coupler 302, power is transmitted to the stirring shaft 303, the stirring shaft 303 penetrates the top of the fermentation tank and is sealed through the sealing ring 304, while ensuring the sealing of the equipment, the stirring short rod 308 and the stirring long rod 309 on the shaft are driven to rotate, the stirring long rod 309 stirs the materials in the tank in a large range, so that the materials are fully mixed, and the phenomena of precipitation or caking are avoided, while the stirring short rod 308 is located between the clearances of the adjacent heating discs 311, when the materials are stirred, the heat transfer between the heat conducting oil and the materials can be effectively assisted, the distribution uniformity of heat in the materials is further improved, the temperature regulation speed is accelerated, and the temperature control effect is strengthened.

[0038] Finally, the temperature sensor continuously monitors the temperature in the fermentation tank and feeds back the latest temperature data to the temperature control module in the control cabinet 2, and the temperature control module adjusts the opening degree of the first temperature control electromagnetic valve 313 and the second temperature control electromagnetic valve 314 and the rotating speed of the circulating pump 317 according to the feedback data, when the temperature approaches or reaches the preset value, the temperature control electromagnetic valves 313 and 314 reduce the flow of the heat conducting oil, the circulating pump 317 reduces the rotating speed, so that the circulating speed of the heat conducting oil slows down and the heat transfer is reduced, if the temperature still deviates greatly from the preset value, the control intensity is increased, so that the temperature in the fermentation tank is always stabilized in the accurate interval suitable for fermentation, and the stable operation of the whole fermentation process is maintained through the above-mentioned circulation and repetition.

[0039] The above are preferred embodiments of the application, and do not limit the protection scope of the application, therefore: any equivalent changes made on the structure, shape, principle of the application should be covered in the protection scope of the application.
