Description

Technical Field

[0001] This utility model relates to the field of liquid storage tank technology, and in particular to a coil radiator for uniform temperature distribution in liquid storage tanks. Background Technology

[0002] In the production fields of chemical, food and pharmaceutical industries, it is often necessary to heat or cool the liquid in the storage tank to control the reaction or storage conditions. A common technical solution is to install heat exchange coils in the storage tank and regulate the temperature of the liquid by passing hot or cold media through the coils.

[0003] However, when heat exchange is carried out solely by heat exchange coils, heat transfer mainly depends on the natural convection of the liquid, which is usually inefficient. Especially for large-volume storage tanks or liquids with high viscosity, the liquid inside the tank is prone to obvious temperature gradients, that is, the temperature changes drastically in the area near the coils, while the temperature response in the area far from the coils is lagging, resulting in extremely uneven overall temperature distribution, which in turn affects product quality or the stability of the reaction process.

[0004] To address the issue of uneven temperature distribution, existing technologies have further incorporated stirring devices. By installing a stirring paddle inside the tank, the liquid is forcibly stirred, which can significantly enhance heat transfer efficiency and allow the liquid temperature to quickly reach a uniform state. However, in traditional stirred tank designs, the driving components, such as the motor and reducer that drive the stirring shaft, are usually directly mounted on the top of the tank. The stirring shaft passes through the tank cover and is connected to the inside of the tank via a seal. Once the seal ages or fails, or if the driving components leak lubricating oil, contaminants may drip directly into the liquid inside the tank. For industries with extremely high cleanliness requirements, such as food and pharmaceuticals, this kind of contamination is unacceptable. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a coil radiator with uniform temperature distribution in storage tanks, aiming to improve the problems of uneven temperature distribution, easy contamination of the storage liquid by the drive mechanism, and low heat dissipation efficiency in existing liquid storage equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a coil radiator for uniform temperature distribution in a storage tank, comprising: a tank body, a first heat exchange tube disposed inside the tank body, a stirring shaft disposed inside the tank body, and a drive assembly; and further comprising a heat dissipation assembly disposed outside the tank body;

[0007] The heat dissipation component is provided with a second heat exchange tube inside; the drive component specifically includes a motor, a drive shaft connected to the motor, a first bevel gear fixed to the end of the drive shaft, and a second bevel gear connected to the end of the stirring shaft.

[0008] The first heat exchange tube and the second heat exchange tube are in cyclic communication to form an internal and external double circulation loop for the heat exchange medium; the drive component is located outside the tank and transmits power from outside the tank to the internal stirring shaft by means of the meshing of its first bevel gear with the second bevel gear of the stirring shaft.

[0009] Preferably, the first heat exchange tube and the second heat exchange tube are connected in a loop through a first return pipe, a second return pipe, a first branch pipe, a second branch pipe, a first loop pipe, and a second loop pipe.

[0010] Preferably, the device further includes a heat exchange assembly comprising a first heat exchange tube, a second heat exchange tube, and a pipe that circulates between the two.

[0011] Preferably, the heat dissipation component is equipped with a fan inside and has heat dissipation windows on its outer wall to enhance the heat dissipation effect on the heat exchange medium.

[0012] Preferably, the device further includes a mounting base, through which the motor is fixed to ensure the stability of the drive assembly operation.

[0013] Preferably, the device further includes a protective cover, which is fitted over the connection between the motor and the drive shaft to provide safety protection for the transmission mechanism.

[0014] Preferably, the device further includes a base disposed at the bottom of the tank, on which the first heat exchange tube is supported to maintain a stable position of the heat exchange tube within the tank.

[0015] Preferably, the first heat exchange tube is a coil structure to increase its heat exchange contact area with the liquid stored in the tank.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, by setting a stirring shaft and blades and driving them to rotate by an external drive component, the liquid in the tank can be forcibly stirred, which effectively solves the problem of local overheating or undercooling of the liquid caused by insufficient natural convection during the heat exchange process, and significantly improves the temperature uniformity of the stored liquid.

[0018] 2. In this utility model, the drive assembly consisting of a motor, transmission shaft, and gears is set outside the tank body. Power is transmitted to the internal stirring shaft through a bevel gear mechanism, which realizes complete physical isolation between the drive mechanism and the liquid stored in the tank. This fundamentally eliminates the risk of contaminants such as lubricating oil and wear particles entering the liquid, ensuring the purity and safety of the liquid. It is especially suitable for occasions with high cleanliness requirements. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-5This utility model provides an embodiment of a coil radiator for uniformly distributing the temperature of a storage tank, comprising a tank body 4, a first heat exchange tube 503 disposed inside the tank body 4, a stirring shaft 6 also disposed inside the tank body 4, and a drive assembly 3. A blade 9 is fixedly connected to the outer wall of the stirring shaft 6. The drive assembly 3 is drively connected to the stirring shaft 6 to drive the stirring shaft 6 to rotate within the tank body 4. The structural feature of this device is that it has a heat dissipation assembly 1 disposed outside the tank body 4, and a second heat exchange tube 504 disposed inside the heat dissipation assembly 1. The second heat exchange tube 504 and the first heat exchange tube 503 inside the tank body 4 form a complete heat exchange medium circulation loop. Simultaneously, the drive assembly 3 is disposed outside the tank body 4 and transmits power through a bevel gear mechanism. The stirring shaft 6 is delivered to the inside of the tank 4. The heat exchange medium circulation loop is composed of a heat exchange assembly 5, which includes a first heat exchange tube 503, a second heat exchange tube 504, and multiple pipes connecting the two. The inlet end of the first return pipe 501 is used to connect to an external heat exchange medium source, and its outlet end is fixedly connected to a first ring pipe 507. The first ring pipe 507 is fixedly connected to the inlet end of the first heat exchange tube 503 via a first branch pipe 505. To increase the contact area with the liquid inside the tank 4, the first heat exchange tube 503 is specifically a coil structure. The outlet end of the first heat exchange tube 503 is fixedly connected to the second ring pipe 508 via a second branch pipe 506. The second ring pipe 508 is then fixedly connected to the inlet end of the second heat exchange tube 504 via a second return pipe 502. The outlet end of the second heat exchange tube 504 can return to the heat exchange medium source. A fan 101 is fixedly installed inside the heat dissipation assembly 1. The fan 101 is used to form a stable heat dissipation air duct inside the heat dissipation assembly 1 to force air cooling of the heat exchange medium flowing through the second heat exchange tube 504. Multiple heat dissipation windows 102 are opened on the outer wall of the heat dissipation assembly 1 to exhaust the hot air after heat exchange. The drive assembly 3 includes a motor 301, a drive shaft 302, a first bevel gear 303 and a second bevel gear 304. The output shaft of the motor 301 is fixedly connected to one end of the drive shaft 302. The first bevel gear 303 is fixedly connected to the other end of the drive shaft 302. The second bevel gear 304 is fixedly connected to the top of the stirring shaft 6 located outside the tank 4. A first bevel gear 303 meshes with a second bevel gear 304, and the rotation axis of the first bevel gear 303 is perpendicular to the rotation axis of the second bevel gear 304. This structure is used to convert the horizontal rotation output by the motor 301 into the vertical rotation of the stirring shaft 6. In order to achieve stable operation and safety protection of the device, the motor 301 is fixedly connected to the frame of the device through the fixed base 2 to ensure that it outputs power stably during operation. A protective cover 7 is provided at the connection between the motor 301 and the transmission shaft 302 to prevent external impurities from affecting the transmission mechanism or causing accidental contact. A base 8 is fixedly connected to the bottom of the tank 4, and the coil part of the first heat exchange tube 503 is supported on the base 8 to maintain its stable position in the tank 4.

[0028] Working principle: The heat exchange medium enters from the first return pipe 501, flows sequentially through the first ring pipe 507 and the first branch pipe 505, and then enters the first heat exchange tube 503 located inside the tank 4. Here, the heat exchange medium exchanges heat with the liquid stored in the tank 4 through the tube wall of the first heat exchange tube 503 to regulate the temperature of the stored liquid. At the same time, the motor 301 of the drive assembly 3 starts and outputs power. The power is transmitted through the transmission shaft 302 to the first bevel gear 303 fixed at its end, causing the first bevel gear 303 to rotate. Since the first bevel gear 303 meshes with the second bevel gear 304, its rotation drives the second bevel gear 304 to rotate, which in turn drives the stirring shaft 6 fixedly connected to the second bevel gear 304 to rotate around its own axis. The rotation of the stirring shaft 6 drives the blades 9 fixed on it to continuously stir the stored liquid in the tank 4, forcibly stirring the liquid. Liquid convection ensures thorough mixing of the liquid near the first heat exchange tube 503 with the liquid further away, guaranteeing a uniform temperature distribution throughout the tank 4. After heat exchange with the stored liquid is completed, the heat exchange medium, whose temperature has changed, flows out of the first heat exchange tube 503 and sequentially enters the second branch tube 506, the second ring tube 508, and the second return tube 502. Finally, it is guided to the second heat exchange tube 504 located inside the heat dissipation assembly 1. The fan 101 inside the heat dissipation assembly 1 operates, generating a forced airflow that flows over the outer surface of the second heat exchange tube 504, carrying away the heat carried by the heat exchange medium and completing the cooling or heating of the heat exchange medium. The air carrying heat is then discharged through the heat dissipation window 102. The cooled or heated heat exchange medium then enters the next cycle. Through the synergistic effect of the above heat exchange and stirring processes, efficient and uniform regulation of the stored liquid temperature is achieved.
