Description

Technical Field

[0001] The utility model relates to the technical field of vacuum storage tanks, in particular to a vacuum storage tank for storing industrial gases. Background Art

[0002] Gas products come in a wide variety, broadly categorized as industrial gases and specialty gases. Depending on their intended use, gases are subject to stringent requirements for purity and composition, the maximum allowable level of harmful impurities, and packaging, storage, and transportation. These high-tech, high-value-added products are typically used for storing and transporting gases (such as liquefied gases, hydrogen, oxygen, and helium). They utilize vacuum insulation technology to maintain the gas's liquid state at low temperatures, preventing evaporation and leakage. They are widely used in industries such as chemical, metallurgy, electronics, and healthcare.

[0003] In actual use, existing vacuum storage tanks for industrial gas storage are not convenient for maintaining the low temperature state of the liquid gas in the tank, which affects the stability of long-term storage.

[0004] After searching the existing patents: a high-sealed deoxygenation vacuum storage tank (publication number: CN208165770U), which includes a tank body, an insulation layer, an isolation membrane, a temperature control device, an exhaust device, a feed pipe, a discharge pipe, a bracket, a motor, a stirring shaft, a stirring blade and a quick-opening manhole. The temperature control device is installed on one side of the tank body. The temperature control device consists of a temperature control tube, a heating device, a cooling device, a temperature monitor and a barrier layer. The utility model can regulate the temperature inside the tank body to ensure the optimal temperature for material storage, and can stir the material to avoid precipitation or small particles of the material. The tank body is a vertical structure, occupies a small area, and can be moved freely.

[0005] Although the above patent can control the temperature inside the tank to ensure the optimal temperature for material storage, and can stir the material to prevent the material from sedimentation or small particles, the tank is a vertical structure with a small footprint and can be moved freely, but it is not convenient to increase the sealing with the external pipe. When transporting gas, the leakage of industrial gas can easily cause harm to personnel.

[0006] Therefore, it is necessary to invent a vacuum storage tank for industrial gas storage to solve the above problems. Utility Model Content

[0017] (3) Beneficial effects

[0018] The utility model provides a vacuum storage tank for industrial gas storage, which has the following beneficial effects:

[0019] 1. The vacuum storage tank for industrial gas storage is provided with a fixed sealing component and a movable sealing component. When in use, two sets of sealing gaskets are inserted into both sides of the sealing steel ring, and then the installed sealing steel ring is inserted into the connecting disk. When the external pipe is aligned and plugged in, the fixed ring squeezes the movable ring, so that the telescopic spring on one side of the movable ring is deformed under force to generate elastic force, and then the fixed ring is squeezed in the opposite direction to seal. Then, the upper clamping block and the lower clamping block are clamped on the connecting disk for installation. Through the two-layer sealing, the effect of increasing the sealing with the external pipe is achieved, preventing industrial gas leakage from causing harm to personnel during gas transportation, and improving the safety of the vacuum storage tank for industrial gas storage.

The vacuum storage tank for industrial gas storage, through the setting of the isolation component and the pressure measuring component, when in use, the anti-corrosion layer, that is, the ceramic coating, can increase the supporting strength of the inner tank and reduce external corrosion. The interval layer, that is, the foam layer, can effectively isolate the internal and external temperatures and reduce heat transfer. At the same time, when in use, the negative pressure pump is started to extract the air between the outer tank body and the inner tank. At the same time, the pressure sensor detects the internal pressure. When the pressure exceeds the set value, a signal is sent to the controller, and the controller controls the negative pressure pump to stop. The vacuum principle is used to effectively insulate, thereby maintaining the low temperature of the liquid gas in the inner tank, thereby improving the thermal insulation capacity of the vacuum storage tank for industrial gas storage.
