Description

Technical Field

[0001] This utility model relates to the field of storage tank technology, and in particular to an inert gas storage tank. Background Technology

[0002] Inert gases are usually stored in tanks, and after filling, the tanks are generally placed outdoors.

[0003] However, outdoor inert gas storage tanks are susceptible to thermal expansion and a sharp increase in pressure during the high temperatures of summer, while contraction and a drop in pressure during the low temperatures of winter can disrupt the normal supply and use of gas. Frequent temperature fluctuations and resulting pressure fluctuations can impact valves, leading to a decrease in the tank's sealing performance. This decrease in sealing performance can cause gas leaks, wasting resources and potentially causing environmental pollution and safety hazards. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an inert gas storage tank that reduces changes in gas pressure inside the tank due to weather conditions, thereby improving the safety of the inert gas storage tank.

[0005] An inert gas storage tank according to an embodiment of the present invention includes a tank body, a temperature control device, a temperature detector, and an outer shell. An inlet pipe and an outlet pipe are connected to the outer wall of the tank body, and valves are installed on both the inlet and outlet pipes. A safety valve is connected to the top of the tank body. The temperature control device includes a heat insulation layer, a heat exchange assembly, and a temperature control assembly. The heat exchange assembly is arranged around the outer peripheral wall of the tank body. The heat insulation layer covers the tank body and also covers the heat exchange assembly. The temperature control assembly is connected to the heat exchange assembly. The temperature detector is disposed on the outer wall of the tank body and is electrically connected to the temperature control assembly via a controller. The temperature detector is used to detect the temperature of the tank body and to control the temperature of the heat exchange assembly through the temperature control assembly. The outer shell covers the temperature control device and is used to enclose the tank body, the temperature control device, and the temperature detector.

[0006] It has at least the following beneficial effects:

[0007] The thermostatic device, through its insulation layer, reduces heat exchange between the tank and the external environment. The heat exchange components, arranged around the outer perimeter of the tank, work in conjunction with the temperature control components and temperature detectors to actively adjust the temperature of the heat exchange components based on changes in the tank temperature, thus effectively controlling the tank temperature. The outer shell encapsulates the tank, thermostatic device, and temperature detectors, enhancing the overall structural stability and protection of the storage tank. Because of the thermostatic device, the inert gas storage tank significantly reduces internal gas pressure fluctuations caused by weather changes, mitigating the impact of frequent pressure fluctuations on the valves, effectively maintaining the tank's sealing performance, and preventing gas leakage. This not only saves resources but also eliminates environmental pollution and safety hazards, greatly improving the safety and reliability of the inert gas storage tank, ensuring the normal supply and use of gas. Furthermore, the installation of inlet and outlet pipes and valves within the tank allows for stable inert gas flow, while the safety valve provides pressure relief protection in case of abnormal tank pressure.

The temperature control assembly includes a power supply and a coolant circulator, with the power supply electrically connected to the heating wire and the coolant circulator connected to the coolant coil. Both the power supply and the coolant circulator are electrically connected to a temperature detector via a controller. The temperature detector is used to detect the temperature of the tank and to control the operating status of the power supply or the coolant circulator via the controller.

[0009] According to some embodiments of this utility model, the heat exchange component is a heat exchange coil, which is arranged around the outer peripheral wall of the tank. The temperature control component is an air conditioner. The heat exchange coil serves as the evaporator of the air conditioner and is connected to the coolant circulation pipeline of the air conditioner. The air conditioner is used to control the temperature of the heat exchange coil.

[0010] According to some embodiments of the present invention, the coolant circulator includes a coolant reservoir, a circulation pump, and a cooling fan. The coolant reservoir is connected to a coolant coil. The circulation pump is installed on the circulation pipeline between the coolant reservoir and the coolant coil. The circulation pump is used to drive the coolant circulation. The part of the coolant coil away from the tank is provided with heat dissipation fins, and the cooling fan is installed on the heat dissipation fins.

[0031] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0033] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0034] Reference Figures 1 to 4This utility model discloses an inert gas storage tank, including a tank body 100, a temperature control device 200, a temperature detector 300, and an outer shell 400. An inlet pipe 110 and an outlet pipe 120 are connected to the outer wall of the tank body 100. Valves 130 are installed on both the inlet pipe 110 and the outlet pipe 120. A safety valve 140 is connected to the top of the tank body 100. The temperature control device 200 includes a heat insulation layer 210, a heat exchange assembly 220, and a temperature control assembly. The heat exchange assembly 220 is arranged around the outer peripheral wall of the tank body 100. A temperature control component is connected to the heat exchange component 220 and covers the tank body 100. A temperature detector 300 is installed on the outer wall of the tank body 100 and is electrically connected to the temperature control component via a controller. The temperature detector 300 is used to detect the temperature of the tank body 100 and control the temperature of the heat exchange component 220 through the temperature control component. A housing 400 covers the thermostat 200 and is used to enclose the tank body 100, the thermostat 200, and the temperature detector 300. Understandably, the temperature control device 200 primarily functions to regulate temperature, not to maintain a constant temperature within the device itself, but rather to adjust the temperature of the tank 100 to prevent excessive temperature fluctuations. The positions of the inlet pipe 110 and outlet pipe 120 can be interchanged as needed. The inlet pipe 110 and outlet pipe 120 are mainly used for inflation and deflation. The controller is a conventional controller, including a PLC or a circuit board with integrated chips, or even a computer. The electrical connection method is a standard method used in the field, as long as it can be used for control. When the temperature detector 300 detects that the temperature of the tank 100 is outside the allowable range, the conventional controller can control the heating or cooling of the heat exchange component 220 through the temperature control component, thereby adjusting the temperature of the tank 100. Because the detection is real-time, the temperature control is also dynamic, meaning the temperature of the tank 100 is maintained constant within the allowable range.

[0035] It should be noted that the temperature control device 200 reduces heat exchange between the tank 100 and the outside environment through the insulation layer 210. The heat exchange component 220 is arranged around the outer peripheral wall of the tank 100. In conjunction with the temperature control component and the temperature detector 300, the temperature of the heat exchange component 220 can be actively adjusted according to the temperature change of the tank 100, thereby effectively controlling the temperature of the tank. The outer shell 400 encapsulates the tank 100, the temperature control device 200 and the temperature detector 300, which improves the structural stability and protection of the entire storage tank. Because of the thermostatic device 200, the inert gas storage tank significantly reduces the pressure fluctuations of the gas inside the tank caused by weather changes, reduces the impact of frequent pressure fluctuations on the valve 130, effectively maintains the sealing performance of the storage tank, and avoids gas leakage. This not only saves resources but also eliminates environmental pollution and safety hazards, greatly improving the safety and reliability of the inert gas storage tank and ensuring the normal supply and use of gas. In addition, by setting the inlet pipe 110, outlet pipe 120 and valve 130 in the tank body 100, the stable entry and exit of inert gas can be achieved, and the setting of safety valve 140 provides pressure relief protection when the tank pressure is abnormal.

[0036] In some embodiments, the heat exchange assembly 220 includes a heating wire 221 and a coolant coil 222, both of which are arranged around the outer peripheral wall of the tank 100. The temperature control assembly includes a power supply 231 and a coolant circulator 232. The power supply 231 is electrically connected to the heating wire 221, and the coolant circulator 232 is connected to the coolant coil 222. Both the power supply 231 and the coolant circulator 232 are electrically connected to a temperature detector 300 via a controller. The temperature detector 300 is used to detect the temperature of the tank 100 and to control the operating status of the power supply 231 or the coolant circulator 232 via the controller. It should be noted that the heating wire 221 is covered with a flame-retardant material or an insulating plastic sleeve.

[0037] Reference Figure 4 In some embodiments, the heat exchange component 220 is a heat exchange coil 223, which is arranged around the outer peripheral wall of the tank 100. The temperature control component is an air conditioner, and the heat exchange coil 223 serves as the evaporator of the air conditioner, connected to the air conditioner's coolant circulation pipeline. The air conditioner is used to control the temperature of the heat exchange coil 223. It is understood that the air conditioner is a common type of air conditioner, and the heat exchange coil 223 is a pipe used to circulate the cooling medium. The cooling or heating of the heat exchange coil 223 is controlled by the air conditioner's heating and cooling control, thereby achieving temperature control.

[0038] In some embodiments, the coolant circulator 232 includes a coolant reservoir 232a, a circulation pump 232b, and a cooling fan 232c. The coolant reservoir 232a is connected to a coolant coil 222. The circulation pump 232b is disposed on the circulation pipeline between the coolant reservoir 232a and the coolant coil 222, and is used to drive the coolant circulation. The portion of the coolant coil 222 away from the tank 100 is provided with heat dissipation fins 222a, and the cooling fan 232c is mounted on the heat dissipation fins 222a. It should be noted that the coolant reservoir 232a, the circulation pump 232b, the cooling fan 232c, and the power supply 231 are all mounted on the housing 400. The housing 400 not only protects the tank 100 but also provides support for the coolant reservoir 232a, the circulation pump 232b, the cooling fan 232c, and the power supply 231. Although the cooling fan 232c is mounted on the heat sink 222a, the heat sink 222a can be mounted on the outer casing 400. That is, the pipe is set and fixed against the outer casing 400, and then the heat sink 222a is mounted on the pipe, and then the cooling fan 232c is mounted on the heat sink 222a.

[0039] In some embodiments, a support base 500 is also included, which supports the tank 100. A roller 510 is provided at the lower end of the support base 500, and a locking mechanism 520 is provided on the roller 510. The locking mechanism 520 is used to lock or release the roller 510. It is understood that the support base 500 can move freely via the roller 510, facilitating transfer and installation in open areas. The roller 510 and its locking mechanism 520 are common features.

[0040] In some embodiments, the outer casing 400 is fitted onto the outside of the tank 100, and the lower end of the outer casing 400 is detachably connected to the support base 500. The inner wall of the tank 100 is coated with an anti-corrosion coating, and the outer casing 400 is made of stainless steel. A pressure gauge 150 is connected to the top of the tank 100. The heat insulation layer 210 is a cotton layer or a foam layer. It is understood that the anti-corrosion coating is a conventional anti-corrosion coating used for the metal inner cavity of a tank.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
