Description

Technical Field

[0001] The present application relates to the technical field of tank combination structures, and in particular to an integrated tank and refrigeration component combination structure. Background Art

[0002] An integrated tank and refrigeration unit combination typically refers to equipment used for cryogenic storage, combining a tank and refrigeration components to achieve an efficient and stable cryogenic environment. This structure is widely used in cryogenic and ultra-cryogenic applications, such as liquid nitrogen storage systems, LNG storage tanks, and tank containers. The tank and refrigeration unit are typically connected through pipes and valves. However, this connection is susceptible to corrosion from air oxidation at the joints, which can compromise sealing and lead to leaks in the combined pipe structure. This can pose a safety hazard if not promptly identified and addressed. Utility Model Content

[0003] One of the purposes of the present application is to provide an integrated tank and refrigeration component combination structure to solve the problem that the sealing performance of the existing tank body and refrigeration component combination structure decreases after aging, resulting in leakage that cannot be discovered and handled in time.

[0004] To achieve the above objectives, the technical solution adopted in this application is: an integrated tank body and freezing component combination structure, including a liquefaction tank, a first connecting head, a fastener and a pressure gauge. A control valve is installed on the top of the liquefaction tank, and a first connecting head is provided on one side of the control valve. There are two first connecting heads, and the two first connecting heads are threadedly connected to the control valve and one end of the freezing component respectively. The first connecting head is connected to the second connecting head. There are two second connecting heads, and the two second connecting heads are respectively welded to one end of the pressure maintaining tube and one end of the three-way valve. A pressure gauge is installed on the outside of the pressure maintaining tube, and the detection ends of the pressure gauge are all located inside the pressure maintaining tube. The other end of the pressure maintaining tube is connected to the three-way valve.

[0005] Preferably, a card slot is provided at one end of the first connector and the second connector, and the card slots at one end of the first connector and the second connector are connected by rotating and fitting with each other, and fasteners are provided on the outside of the first connector and the outside of the second connector, wherein a sealing ring is placed between the first connector and the second connector, and the sealing between the first connector and the second connector is further improved by the sealing ring.

[0006] Preferably, the fastener includes a base welded to one side of the first connecting head, one side of the base is connected to one end of the wrench, a pull rod is inserted into the inside of the wrench, the other end of the pull rod is provided with a hole groove, and the hole groove at the other end of the pull rod is engaged with the connecting buckle, and the surface of one side of the connecting buckle is welded to the surface of the second connecting head. By placing one end of the pull rod on the connecting buckle and then pulling the wrench, the wrench can drive the pull rod to be pulled through the rotating shaft, so that the first connecting head and the second connecting head can be tightened again.

[0007] Preferably, the pull rod is located on the outer wall of one end of the rotating shaft and has a threaded structure, and the pull rod is connected to the internal thread of the rotating shaft. By rotating the pull rod, the extended length of the pull rod can be adjusted, which is conducive to adjusting the tension of the first connector and the second connector bracket.

[0008] Preferably, a hole groove is provided on the surface of one end of the base, and the hole groove on the surface of one end of the base is aligned with the hole groove at one end of the wrench, and a C-shaped clip is inserted into the hole groove. The C-shaped clip enables one end of the wrench to be firmly connected to the base, which helps to prevent the wrench from loosening due to rotation.

[0009] Preferably, a switching valve is provided on one side of the pressure gauge, so that the switching valve is used to switch the gas circulation inside the pressure maintaining tube. A flow meter is installed on the outside of the other end of the pressure maintaining tube, and the detection end of the flow meter is located inside the pressure maintaining tube. When a leak occurs inside the pressure maintaining tube, the flow meter will detect the gas circulation at the moment the control valve is opened, which is conducive to further determining the leak.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] (1) The integrated tank body and refrigeration component combination structure, the liquefied tank is connected to the refrigeration component through a pressure-maintaining pipe. By keeping the switching valve in the open state at all times, when disconnecting the connection between the liquefied tank and the refrigeration component, it is only necessary to turn the control valve and the three-way valve to make the inside of the pressure-maintaining pipe between the three-way valve and the flow meter pressure gauge disconnected from the liquefied tank and the refrigeration component. Each time it is used, by opening the control valve and observing whether the pressure gauge value changes, it is possible to quickly determine whether there is a leak at the connection between the liquefied tank and the three-way valve. When the pressure gauge value changes, it is possible to know in time whether there is a risk of leakage in the pipeline, which is conducive to timely discovery and treatment, thereby improving the safety of the combined structure.

[0012] (2) The integrated tank body and the frozen part combination structure can realize the quick connection and disassembly of the combination interface through the mutual locking structure of the first connector and the second connector, thereby improving the convenience of use and replacement. When a gap appears between the first connector and the second connector, resulting in a decrease in sealing, by placing one end of the pull rod on the connecting buckle and then pulling the wrench, the wrench can drive the pull rod to be pulled through the rotating shaft, so that the first connector and the second connector can be tightened again, which is conducive to avoiding leakage at the connection between the first connector and the second connector.

A control valve 2 is installed on the top of the liquefaction tank 1, and a first connecting head 3 is provided on one side of the control valve 2. There are two first connecting heads 3, and the two first connecting heads 3 are respectively threadedly connected to the control valve 2 and one end of the refrigeration system 10. The first connecting head 3 is connected to the second connecting head 4. There are two second connecting heads 4, and the two second connecting heads 4 are respectively welded to one end of the pressure-keeping pipe 6 and one end of the three-way valve 5. A pressure gauge 8 is installed on the outside of the pressure-keeping pipe 6, and the detection ends of the pressure gauge 8 are all located inside the pressure-keeping pipe 6. The other end of the pressure-keeping pipe 6 is connected to the three-way valve 5. A switching valve 7 is provided on one side of the pressure gauge 8, so the switching valve 7 is used to switch the gas circulation inside the pressure-keeping pipe 6. A flow meter 11 is installed on the outside of the other end of the pressure-keeping pipe 6, and the detection end of the flow meter 11 is located inside the pressure-keeping pipe 6. The liquefaction tank 1 is connected to the refrigeration system 10 through the pressure-keeping pipe 6.
