Description

Technical Field

[0001] This utility model relates to the field of fluid heating equipment technology, specifically a fluid tank. Background Technology

[0002] In industries such as chemical, pharmaceutical, and food processing, solvents inside tanks often require heating. Traditional heating methods typically involve directly heating the air inside the tank with heating elements, and then transferring heat to the solvent via air conduction. This method has significant drawbacks: air has a low heat capacity and low heat transfer efficiency, resulting in slow heating and high energy consumption; temperature control is unstable and prone to large fluctuations, affecting process stability; excessively high surface temperatures of the heating elements can lead to localized solvent overheating, decomposition, coking, or deterioration, affecting product quality and posing safety risks; furthermore, direct heating can shorten the lifespan of the heating elements and lead to frequent maintenance. Therefore, there is an urgent need for a fluid heating device that can achieve efficient, uniform, stable, and safe heating to meet the precise temperature control requirements and reliable equipment operation demands of modern production. Utility Model Content

[0003] The purpose of this invention is to provide a fluid tank to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fluid tank, comprising a fluid tank body and a heating tube assembly horizontally disposed within the fluid tank body. The heating tube assembly includes a first tank and a second tank arranged parallel to each other. The first tank and the second tank are connected to an internal cavity via a connecting pipe. Distilled water is encapsulated inside the first tank and the second tank, and each of the first tank and the second tank is provided with a heating tube for heating the distilled water and heating the solvent inside the fluid tank body through hydrothermal transfer. The bottom of the first tank is provided with a drain outlet and the top is provided with a water inlet. The top of the second tank is provided with an overflow outlet, and the horizontal height of the water inlet is higher than that of the overflow outlet.

[0005] Preferably, the first tank is equipped with a level switch for detecting the liquid level inside the tank.

[0006] Preferably, the first tank and the second tank are respectively provided with a first flange plate at one end extending from the fluid tank body, and the heating pipe is installed on the first flange plate and extends into the corresponding tank body.

[0007] Preferably, the first tank and the second tank are fixedly installed on the side wall of the fluid tank body via a second flange plate.

[0008] Preferably, a connecting plate for fixing the two tanks is provided between the first tank and the second tank.

[0009] Preferably, a handle for pushing or pulling out the heating tube assembly is provided between the first tank and the second tank.

[0010] Compared with existing technologies, this utility model provides a fluid tank with the following advantages: By employing hydrothermal conduction, this utility model first heats the distilled water sealed inside the tank using a heating tube, and then uniformly and stably transfers heat to the solvent through the water medium. This significantly improves heat transfer efficiency and temperature uniformity, avoids localized overheating, and enhances the safety and reliability of the heating process. Furthermore, the inclusion of an overflow outlet and a level switch allows for visual and controllable liquid level monitoring, facilitating operation and maintenance. The overall structure is compact, easy to install, and suitable for various fluid heating scenarios, demonstrating good practicality and promotional value. Attached Figure Description

[0014] The technical solutions of the present utility model will now be described with reference to the accompanying drawings in the embodiments of the present utility model:

[0015] like Figure 1-2 As shown, the present invention provides a fluid tank, including a fluid tank body 1 and a heating tube assembly 2 horizontally disposed within the fluid tank body 1. The heating tube assembly 2 includes a first tank 21 and a second tank 22 arranged parallel to each other. The first tank 21 and the second tank 22 are connected to an internal cavity via a connecting pipe 3, allowing distilled water to flow and circulate freely between the two tanks, ensuring uniform heat distribution. Distilled water is encapsulated inside the first tank 21 and the second tank 22 as a heat transfer medium. Heating tubes 23 are disposed inside both the first tank 21 and the second tank 22 for heating the distilled water and heating the solvent inside the fluid tank body 1 through hydrothermal transfer.

[0016] The first tank 21 has a drain port 4 at its bottom for draining liquid during maintenance or replacement of the heat transfer medium; and a water inlet 5 at its top for adding distilled water. The second tank 22 has an overflow port 6 at its top for draining excess water and air during water filling, preventing excessive liquid level and ensuring the system cavity is completely filled. The water inlet 5 is positioned higher than the overflow port 6; this design ensures that air inside the tank can naturally escape through the overflow port during water filling, preventing air pockets and guaranteeing heat transfer efficiency.

[0017] The first tank 21 is equipped with a level switch 7 to detect the liquid level inside the tank. When the liquid level is too low, a signal is sent and the power to the heating element is cut off, effectively preventing dry-burning accidents and greatly improving the safety and service life of the equipment. The first tank 21 and the second tank 22, extending from one end of the fluid tank body 1, are respectively equipped with a first flange plate 8 for installing and fixing the heating element 23. The heating element 23 is installed on the first flange plate 8 and extends into the corresponding tank body. After the power is turned on, it can heat distilled water. The first tank 21 and the second tank 22 are fixedly installed on the side wall of the fluid tank body 1 via a second flange plate 9. This flange connection method is structurally stable and reliable, and facilitates the overall assembly and disassembly of the entire heating element assembly 2.

[0018] To further enhance structural stability, a connecting plate 10 is provided between the first tank 21 and the second tank 22 to fix the two tanks together and prevent displacement or vibration during use. A handle 11 is also provided between the first tank 21 and the second tank 22 to facilitate the operator to push or pull out the heating tube assembly 2 for installation, maintenance or replacement.

[0019] The fluid tank body 1 has a head 12 on the upper part and an observation window 13 on the side for easy observation of the internal working conditions. The bottom of the fluid tank body 1 has a conical bottom 14 structure, which is conducive to solvent discharge and cleaning. The fluid tank body 1 is equipped with reinforcing ribs 15 and support legs 16 on the outside to enhance the overall structural strength and stability.

[0020] The working process and principle of this utility model are as follows: When it is necessary to heat the solvent in the fluid tank, distilled water is first injected into the first tank 21 through the water inlet 5. The water flows into the second tank 22 through the connecting pipe 3 until the water overflows from the overflow port 6, indicating that the system is full of water. After the liquid level switch 7 detects that the liquid level is normal, the heating tube 23 is activated to heat the distilled water. Its core advantage is that the heating tube 23 first heats the distilled water sealed in the tank. Utilizing the high specific heat capacity and strong heat storage capacity of water, a stable and uniformly distributed heat source is formed. The heat is uniformly conducted to the entire outer wall of the first tank 21 and the second tank 22 through the water medium, thereby indirectly heating the solvent in the fluid tank. This indirect water heat transfer method overcomes the disadvantages of traditional heating tubes that directly heat the air, such as low heat capacity, low heat transfer efficiency, large temperature fluctuations, and easy local overheating. The buffering effect of water makes the system have a large thermal inertia. Even if there are slight fluctuations in the heating power, the temperature of the output heat is very stable, thus achieving uniform, efficient, stable, and safe heating of the solvent.

[0021] This invention utilizes indirect heating via water as a medium, combined with a unique dual-tank interconnected structure, to significantly improve heating uniformity and temperature control stability, effectively preventing localized overheating and ensuring fluid quality. Its high thermal efficiency and large thermal inertia help reduce energy consumption and achieve precise temperature control. Simultaneously, liquid level protection and a reliable structural design significantly enhance the equipment's safety and lifespan. Furthermore, its convenient operation and maintenance, along with its rational overall structure, effectively address many shortcomings of traditional direct heating methods. It is particularly suitable for fluid heating scenarios in chemical, pharmaceutical, and food industries where high temperature uniformity and control precision are required, demonstrating outstanding practicality and promotional value.

[0022] The above embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
