[0028] Embodiment

[0029] A fermentation tank temperature increasing device, as Figure 1 shown, includes a heating structure, a conduction structure and a heat conduction structure; wherein, the heating structure includes a heating cylinder 8 and a heating plate 6; the conduction structure includes a water inlet pipe 15 and a return water pipe 16; the heat conduction structure includes an external heating pipeline 19, a connecting pipe 2 and an internal heating spiral pipe 17;

[0030] As Figure 3As shown, the heating plate 6 is arranged inside the heating cylinder 8. The water inlet pipe 15 and the water return pipe 16 are both connected to the heating cylinder 8, and a water pump is arranged on the water inlet pipe 15. The external heating pipeline 19 is spirally connected to the outer side of the tank body 1 of the fermentation tank. Among them, the heating cylinder 8 is used to store a heat-conducting medium, such as water. The heating plate 6 is used to heat the heat-conducting medium inside the heating cylinder 8. Resistance wires are arranged inside the heating plate 6, and heating is realized by supplying power to the heating plate 6. The heating plate 6 is a prior art, so its specific structure will not be described in detail. The heating pipe clings to the outer side of the tank body 1, and the external heating pipeline 19 is used to transfer the temperature of the heat-conducting medium to the outer wall of the tank body 1, so as to realize heating of the outer side of the tank body 1. The water inlet pipe 15 is used to transport the heat-conducting medium inside the heating cylinder 8 into the external heating pipeline 19, and the water pump is used to provide pressure to make the heat-conducting medium inside the water inlet pipe 15 flow. The connecting pipe 2 is used to transport the heat-conducting medium inside the external heating pipeline 19 into the internal heating spiral pipe 17, and the water return pipe 16 is used to transport the heat-conducting medium inside the internal heating spiral pipe 17 into the heating cylinder 8.

[0031] As Figure 2 shown, the internal heating spiral pipe 17 is connected inside the tank body 1. One end of the external heating pipeline 19 is connected to the water inlet pipe 15, and the other end is connected to the connecting pipe 2. One end of the internal heating spiral pipe 17 is connected to the connecting pipe 2, and the other end is connected to the water return pipe 16. The internal heating spiral pipe 17 is used to transfer the temperature of the heat-conducting medium to the inside of the tank body 1, so as to realize heating of the inside of the tank body 1.

[0032] Specifically, when in use, water is used as the heat-conducting medium. The heating plate 6 inside the heating cylinder 8 heats the water inside the heating cylinder 8, and the water inside the heating cylinder 8 is heated into hot water. The water pump transports the hot water inside the heating cylinder 8 into the external heating pipeline 19 through the water inlet pipe 15. When the hot water passes through the spiral external heating pipeline 19, it can evenly transfer heat to the outer wall of the tank body 1, so as to increase the temperature of the tank body 1. Subsequently, the hot water enters the internal heating spiral pipe 17 through the connecting pipe 2, and the internal heating spiral pipe 17 can evenly transfer the heat of the hot water to the inside of the tank body 1. Through the external heating pipeline 19 and the internal heating spiral pipe 17, internal and external heating can be realized simultaneously, which can significantly improve the heating speed of the tank body 1 and effectively prevent the problem of large temperature difference between the inside and outside of the tank body 1.

[0033] In a preferred embodiment, as Figure 3 shown, a cylinder cover 7 is arranged at the top of the heating cylinder 8, and the cylinder cover 7 is hinged to the heating cylinder 8. The hinged cylinder cover is used to facilitate opening the cylinder cover, so as to add a heat-conducting medium into the heating cylinder 8. At the same time, when it is necessary to clean or maintain the inside of the heating cylinder 8, the hinged cylinder cover 7 simplifies this operation, making the cleaning work more efficient, so as to keep the hygiene and performance of the equipment.

[0034] In a preferred embodiment, as Figure 3As shown in the figure, a drain port 10 is provided at the bottom on one side of the heating cylinder 8, and a drain valve 9 is provided on the drain port 10. The drain port 10 is used to drain the heat-conducting medium in the heating cylinder 8, and the drain valve 9 is used to control the opening and closing of the drain port 10. The drain port 10 provides a simple way to drain the heat-conducting medium, facilitating daily cleaning and maintenance work. When it is necessary to replace the heat-conducting medium or clean the heating cylinder 8, the staff can quickly drain the liquid, saving time and labor. Through the design of the drain valve 9, the operator can flexibly control the flow of the heat-conducting medium. When the valve is opened, the heat-conducting medium can be quickly drained, while closing the valve can prevent accidental leakage, enhancing the safety and reliability of the system.

[0035] In a preferred embodiment, as Figure 3 shown, a connecting column 13 is fixedly connected inside the heating cylinder 8, and the heating plate 6 is connected to the connecting column 13; a plurality of heating plates 6 are provided, and the heating plates 6 are evenly spaced on the connecting column 13, and a heating gap 14 is formed between the heating plates 6. More specifically, the heating plates 6 are evenly spaced in the vertical direction, a heating gap 14 is formed between adjacent heating plates 6, and a plurality of heating gaps 14 are distributed from top to bottom. The heat-conducting medium in the heating cylinder 8 can enter the water inlet pipe 15 only after passing through these heating gaps 14. Therefore, the uniformly distributed heating plates 6 and heating gaps 14 up and down can adapt to different amounts of heat-conducting medium. When the heat-conducting medium is less, the heat-conducting medium will only contact the heating plate 6 on one side of the bottom. When the heat-conducting medium is more, the heat-conducting medium will contact the heating plates 6 on both the top side and the bottom side at the same time, so that the heat-conducting medium can be stably heated, preventing the heat-conducting medium from heating up slowly after the amount of the heat-conducting medium increases. Through this design of the heating plate 6, it can ensure that the heating medium in the heating cylinder 8 is stably heated, which is beneficial to heating the tank body 1.

[0036] In a preferred embodiment, as Figure 1 shown, a temperature sensor 12 is provided on the water inlet pipe 15. By means of the temperature sensor 12 installed on the water inlet pipe 15, the temperature change of the heat-conducting medium can be continuously monitored. This enables the system to timely obtain the current temperature of the heat-conducting medium in the heating cylinder 8, thus ensuring the effectiveness of the heating process. By monitoring the real-time temperature, potential safety hazards caused by overheating of the heat-conducting medium can be effectively prevented. At the same time, by intelligently adjusting the heating power, energy conservation can also be achieved, reducing energy consumption. Precise temperature monitoring and control can ensure that the fermentation tank operates within the optimal temperature range, thereby improving the fermentation efficiency and promoting the smooth progress of the reaction process.

[0037] In a preferred embodiment, as Figure 1As shown, an inlet valve 11 is provided on the inlet pipe 15, and a return valve 5 is provided on the return pipe 16. The inlet valve 11 can precisely adjust the inflow rate of the heat-conducting medium, thereby controlling the flow rate of the heat-conducting medium in the heating device. By adjusting the valve opening, the operator can optimize the water flow according to the requirements of the fermentation process to ensure the effective transfer of heat. The presence of the return valve 5 allows the flow rate of the returned heat-conducting medium to be adjusted. When the return valve 5 is opened, the returned hot water can be quickly transported back to the heating cylinder 8 to form a closed-loop cycle; if it is necessary to reduce the temperature or adjust the heat transfer, this valve can be appropriately closed or adjusted to change the thermal equilibrium state of the system. The settings of the inlet valve 11 and the return valve 5 enable the convenient isolation and control of the water flow during system maintenance, repair, or cleaning. This design simplifies the daily maintenance of the equipment and improves the operational convenience. By precisely controlling the inlet flow rate and the return flow rate, it helps to enhance the temperature management during the fermentation process, enabling the fermenter to operate under more ideal temperature conditions, thereby improving the fermentation efficiency and product quality.

[0038] In a preferred embodiment, as Figure 1 shown, a thermal insulation shell 20 is fixedly connected to the outside of the tank body 1. A thermal insulation space 21 is formed between the thermal insulation shell 20 and the tank body 1, and the external heating pipe 19 is arranged in the thermal insulation space 21. The design of the thermal insulation shell 20 can effectively reduce the heat exchange between the surface of the tank body 1 and the external environment. Due to the existence of the thermal insulation space 21, the conduction and retention of heat in the tank body 1 become more efficient, thereby improving the overall thermal energy utilization efficiency of the heating system. This means that under the same input energy conditions, the temperature in the tank body 1 will rise more rapidly, reducing energy loss. When the external heating pipe 19 is located in the thermal insulation space 21, the continuity and uniformity of the heating effect can be ensured. In this way, regardless of how the external environmental temperature changes, the temperature in the tank body 1 can remain relatively stable, which is conducive to the progress of a suitable fermentation or reaction process and ensures the activity of the reactants. The presence of the thermal insulation shell 20 can prevent the direct contact of the external cold air with the tank body 1, thereby reducing the condensation phenomenon caused by the temperature difference. While reducing condensation, it also reduces the corrosion risk of the tank body 1 and related equipment, thereby extending the service life of the equipment.

[0039] In a preferred embodiment, as Figure 2As shown, the cross-section of the external heating pipe 19 is a square structure. This design is to make the contact area between the external heating pipe 19 and the outer surface of the tank body 1 larger. A larger contact area can improve the heat transfer efficiency from the external heating pipe 19 to the tank body 1, ensure that the temperature inside the tank rises quickly and evenly, thus accelerating the fermentation or reaction process and improving production efficiency. The layout of the square external heating pipe 19 helps to better adapt to the shape of the tank body 1 and reduce the temperature difference loss during heat conduction. This means less energy is dissipated in the form of heat, which is particularly important for ensuring the optimal temperature conditions for internal reactions or fermentations.

[0040] In a preferred embodiment, as Figure 2 shown, a support column 4 is fixedly connected inside the tank body 1. A receiving bin 3 is fixedly connected to the top of the support column 4. The receiving bin 3 is connected to the connecting pipe 2, and the internal heating spiral pipe 17 is connected to the receiving bin 3; the internal heating spiral pipe 17 is connected to the connecting pipe 2 through the receiving bin 3. The receiving bin 3 is used to collect the water in the external heating pipe 19 and introduce the water into the internal heating spiral pipe 17. The connection between the internal heating spiral pipe 17 and the connecting pipe 2 through the receiving bin 3 ensures the continuous flow of the heating water, enabling heat to be evenly and efficiently conducted into the tank body 1 in the internal heating spiral pipe 17, improving the overall heat exchange effect. This design ensures a more uniform heat distribution within the system and reduces the occurrence of local overheating or cooling.

[0041] In a preferred embodiment, as Figure 2 shown, the cross-section of the internal heating spiral pipe 17 is a circular structure. This structure of the internal heating spiral pipe 17 is to increase the contact area between the internal heating spiral pipe 17 and the materials inside the tank body 1. The internal heating spiral pipe 17 with a circular cross-section can provide a more uniform contact surface, enabling heat to be more effectively transferred to the materials inside the tank body 1. Compared with a square or rectangular cross-section with more corners, the circular structure reduces dead corners and local cold spots, thus improving the overall heat exchange efficiency.
