Description

Technical Field

[0001] This application relates to the field of liquid oxygen storage tank technology, and more specifically to a liquid oxygen storage tank that is easy to fill. Background Technology

[0002] A liquid oxygen storage tank is a cryogenic pressure vessel specifically designed for storing liquid oxygen; it is also known as a cryogenic liquid oxygen storage tank or cryogenic storage tank. In this application, "liquid oxygen storage tank" refers to a small liquid oxygen storage tank, such as a medical oxygen cylinder.

[0003] There is a liquid oxygen storage tank, such as Figure 1 As shown, the system includes a storage tank body 90, which has a liquid storage chamber, a filling connector 91, and a protective cover 92. The filling connector 91 communicates with the liquid storage chamber. The protective cover 92 is located outside the filling connector 91 and provides external protection for it. To expose the filling connector 91, the protective cover 92 has an arched notch. However, due to the narrow width of the arched notch, during the connection of external pipelines to the filling connector 91, the palm can easily interfere with the protective cover 92, resulting in limited hand movement space. Therefore, extra care must be taken when connecting the protective cover 92 to the walls on both sides of the arched notch.

[0004] Therefore, there is a need for a liquid oxygen storage tank that provides more space at the joint during filling to facilitate filling. Summary of the Invention

[0021] Schematic illustration of a liquid oxygen storage tank for easy filling, reference. Figures 2 to 5 According to a preferred embodiment of the present invention, a liquid oxygen storage tank that is easy to fill includes a tank body 10.

[0022] Specifically, such as Figure 2 As shown, the top of the storage tank body 10 is provided with a filling connector 101 and a protective cover 102. The protective cover 102 is located outside the filling connector 101 and is fixedly connected to the storage tank body 10. The protective cover 102 has a first notch 1021, and the filling connector 101 is directly opposite the first notch 1021.

[0023] It should be noted that during filling, the filling personnel need to pass the external pipe connector through the first notch 1021 and connect it to the filling connector 101 to facilitate the delivery of external liquid oxygen into the storage tank body 10 for storage. Furthermore, by setting the protective cover 102, firstly, the filling connector 101 can be externally protected to prevent direct impact from external objects during transportation; secondly, by setting the protective cover 102, when moving the storage tank body 10, the handling personnel can pass their hands through the first notch 1021 to easily handle the storage tank body 10. However, if the width of the first notch 1021 is large, the protection of the filling connector 101 will be reduced, while if the width of the first notch 1021 is small, the filling personnel's palm may easily interfere with the protective cover 102 when connecting the connector. It should be emphasized that in this application, the width of the first notch 1021 is large to provide sufficient space for the filling personnel to connect the external pipe connector to the filling connector 101.

[0024] Additionally, in this application, such as Figures 2 to 4 As shown, the liquid oxygen storage tank that is easy to fill also includes a collar 20, which is rotatably fitted onto the outside of the protective cover 102. The collar 20 has a second notch 201 and a third notch 202. The width of the second notch 201 is smaller than the width of the first notch 1021, and the width of the third notch 202 is larger than the width of the first notch 1021.

[0025] It should be noted that, under normal conditions, the second notch 201 of the collar 20 is connected to the first notch 1021. Since the width of the second notch 201 is smaller than that of the first notch 1021, the technical defect of insufficient protection for the charging connector 101 due to the larger width of the first notch 1021 is overcome. The collar 20 provides external protection for the charging connector 101. When charging connection is required, the charging personnel can rotate the collar 20 by a predetermined angle and make the third notch 202 face the first notch 1021. Since the width of the third notch 202 is larger than that of the first notch 1021, and the width of the first notch 1021 itself is sufficient to provide clearance, the advantages of having more space at the connector during charging and providing protection for the charging connector 101 under normal conditions are achieved.

[0026] Furthermore, in order to fix the angular position of the collar 20, a first magnet is embedded in the tank body 10 below the collar 20, and a second magnet is provided at the bottom of the collar 20. When the first magnet and the second magnet are attracted, the first notch 1021 is directly opposite the second notch or the third notch.

[0027] Furthermore, in this application, as Figure 3 As shown, the storage tank body 10 includes an outer liner 103, an inner liner 104, an insulation layer 105, and a valve 106. The outer liner 103 has a first chamber 1031, and the inner liner 104 has a second chamber 1041. The inner liner 104 is placed inside the first chamber 1031, and the insulation layer 105 fills the space between the outer wall of the inner liner 104 and the wall of the first chamber 1031. The top of the second chamber 1041 has a flow hole 1042, which communicates with the filling connector 101. The valve 106 is rotatably mounted on the inner liner 104 and can close or open the flow hole 1042.

[0028] It should be noted that the outer liner 103 is made of ordinary carbon steel, the inner liner 104 is made of stainless steel, and the insulation layer 105 is foam. By setting the foam, it helps to reduce the temperature influence between the external temperature and the liquid oxygen inside the inner liner 104. When the valve 106 is turned and the flow hole 1042 is opened, the second chamber 1041 is connected to the outside through the flow hole 1042 and the charging connector 101. Conversely, when the valve 106 closes the flow hole 1042, the second chamber 1041 is closed.

[0029] Furthermore, during filling, when liquid oxygen flows into the second chamber 1041, it exerts an impact force on the inner liner 104, which is then transmitted to the insulation layer 105, providing strength support for the insulation layer 105. Figure 3 As shown, the storage tank body 10 also includes a mesh cylinder 107, which is embedded in the insulation layer 105.

[0030] Furthermore, to specifically achieve the opening or closing of the flow hole 1042 when the valve 106 rotates, as follows: Figure 5As shown, the inner liner 104 has a vertical cylindrical portion 1043 at its top, and the vertical cylindrical portion 1043 has an inner cavity. A shoulder ring 1044 is provided in the middle section of the inner cavity, and the outer wall of the shoulder ring 1044 is fixedly connected to the inner cavity. The fixed connection method includes, but is not limited to, welding. The central hole of the shoulder ring 1044 is the flow hole 1042. One end of the shoulder ring 1044 facing away from the second chamber 1041 is an external cavity 1045, which communicates with the filling connector 101. The valve 106 includes a first screwing component 1061 and a second screwing component 1062. The screwing component 1061 is threadedly connected to the vertical cylinder 1043 and extends into the outer cavity 1045 a predetermined distance. One end of the second screwing component 1062 passes through the flow hole 1042, and the other end of the second screwing component 1062 has an insertion hole and is fixedly connected to the first screwing component 1061. One end of the first screwing component 1061 extending into the outer cavity 1045 extends into the insertion hole. The fixed connection method includes, but is not limited to, adhesive connection. The end of the second screwing component 1062 near the flow hole 1042 has a venting notch and an annular groove for placing the first sealing ring.

[0031] It should be noted that, firstly, one end of the first screwing component 1061 is threaded to the vertical cylinder 1043 and inserted into the outer cavity 1045. Then, glue is applied to the insertion hole of the second screwing component 1062. Subsequently, the second screwing component 1062 is placed into the outer cavity 1045, and one end of the first screwing component 1061 is inserted into the insertion hole, thereby achieving the adhesive connection between the first screwing component 1061 and the second screwing component 1062. Subsequently, the shoulder ring 1044 is placed into the inner cavity and welded to the vertical cylinder 1043. In addition, when both ends of the vent are connected to the outer cavity 1045 and the second chamber 1041 respectively, the second chamber 1041 is connected to the outside.

[0032] Furthermore, to improve sealing, such as Figure 5 As shown, the second screwing member 1062 has a disc portion 1063 at one end away from the flow hole 1042, and a second sealing ring is fitted on one side of the disc portion 1063.

[0033] Furthermore, to divert the liquid oxygen that enters the second chamber 1041 during filling, such as... Figure 5 As shown, the storage tank body 10 also includes a diverter 107, which is located at one end of the flow hole 1042 near the second chamber 1041, and the diverter 107 has a plurality of mesh holes.

[0034] It should be noted that by setting the diverter 107, the large-section liquid oxygen jet becomes multiple small-section liquid oxygen jets after passing through the mesh and flows into the second chamber 1041, which greatly reduces the Reynolds number and changes the flow state from turbulent to laminar flow, which helps to improve the stability of the tank body 10 during filling.

[0035] In addition, to provide cushioning for the diverter 107 after it is subjected to impact, such as Figure 5 As shown, the storage tank body 10 also includes an elastic element 108, the two ends of which are connected to the diverter 107 and the inner liner 104, respectively.

[0036] Furthermore, to ensure the elasticity of the elastic element 108 under low-temperature conditions, the material of the elastic element 108 is austenitic stainless steel.

[0037] In summary, the liquid oxygen storage tank that is easy to fill, based on the embodiments of this application, is explained, which provides advantages such as more space at the joint during filling.

[0038] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from these principles.
