Description

Technical Field

[0001] The present application relates to the technical field of storage tanks, and more specifically to a liquid oxygen storage tank. Background Art

[0002] Liquid oxygen tank is a tank used to store low-temperature liquid.

[0003] There is a liquid oxygen storage tank, such as Figure 1 As shown, it includes a tank body, which has a shell 91. The side wall of the shell 91 has four rectangular side legs 92. The bottom of the shell 91 has a flange interface 93. The top of the shell 91 has multiple hanging rings 94. It should be noted that due to the large outer dimensions of the tank, Figure 2 As shown, when the trailer truck is transporting the tank, it is arranged horizontally, with the four side legs 92 in contact with the bottom wall of the vehicle compartment. Multiple first ropes 95 are then used to tie the tank's side walls, and multiple second ropes 96 are used to tie the eyelets 94 and the flange interface 93 to the vehicle compartment. However, because the tank's side walls and the support legs are both smooth cylindrical surfaces, the axial position limitation of the tank by the first ropes 95 is almost negligible. Their purpose is only to ensure that the side legs 92 are in close contact with the bottom of the vehicle compartment. When the trailer truck is traveling up or down slopes or on bumpy roads, the axial movement of the tank is limited only by the eyelets 94 and the second ropes 96 at the flange interface 93. This places a heavy load on the connection between the flange interface 93 and the outer shell 91, leaving room for further optimization.

[0004] Therefore, there is a demand for providing a liquid oxygen storage tank that is easy to tie for transportation, has a more reasonable load distribution, and is easy to lift. Utility Model Content

[0027] Schematic liquid oxygen tank,

[0028] refer to Figures 3 to 6 According to a preferred embodiment of the present invention, a liquid oxygen storage tank includes a tank body, which includes an outer shell 10, an insulation layer and an inner liner. The insulation layer wraps the inner liner, and the outer shell 10 wraps the insulation layer to provide external protection for the insulation layer and the inner liner.

[0029] Furthermore, if Figure 3 、 Figure 4 and Figure 5 As shown, the side wall of the shell 10 has four rectangularly arranged side feet 101 and a plurality of annular grooves 102 for facilitating rope binding. The top and bottom of the shell 10 respectively have a plurality of first hanging rings 103 and three supporting feet 104, and the supporting feet 104 have a plurality of second hanging rings 1041.

[0030] It should be noted that, during transportation, the tank body is arranged horizontally and placed on the carriage of a trailer truck. At this time, the four side legs 101 are in contact with the bottom wall of the carriage. The rope body is wrapped around the annular groove 102 and tied to both sides of the carriage to achieve close contact between the four side legs 101 and the bottom wall of the carriage. It should also be noted that the groove width of the annular groove 102 is the same as the rope diameter of the rope body. By arranging the annular groove 102 on the side wall of the shell 10, the rope body wrapped in the annular groove 102 is tied to both sides of the carriage and is in a taut state. The rope body also exerts an axial force on the tank body. Limiting to prevent it from moving axially; in addition, during transportation, by connecting the two ends of several ropes to the first lifting ring 103 and the carriage respectively, and by connecting the second lifting ring 1041 to the carriage at the other end of the tank body through several ropes, the axial direction of the tank body is further restricted. It is obvious that, compared with the existing technology, by providing the annular groove 102 on the side wall of the shell 10, the advantages of convenient transportation and more reasonable load distribution are achieved. By providing the second lifting ring 1041 on the supporting foot 104, it is possible to achieve the advantage of not needing to tie the outlet flange of the bottom wall of the tank body during transportation. It should also be noted that by providing the annular groove 102 and the second lifting ring 1041, when the tank body is arranged vertically to the specified position, the annular groove 102 and the second lifting ring 1041 can be clamped or tied by an external iron frame or rope body to achieve auxiliary fixation of the tank body.

[0031] Furthermore, when the tank body is transported to the vicinity of the designated location, a crane is required to lift the tank body and arrange it vertically. In order to avoid the bottom edge of the supporting leg 104 being damaged by external force during the process of lifting the tank body from a horizontal state to a vertical arrangement, and when the tank body is arranged vertically and gradually contacts the horizontal plane, due to the partial tilt of the tank body, one of the supporting legs 104 contacts the horizontal plane first and bears a larger load, in this embodiment of the application, the liquid oxygen storage tank also includes a plurality of buffer assemblies 20, each of the supporting legs 104 is provided with a buffer assembly 20, and each of the buffer assemblies 20 includes a plurality of springs 201, and one end of the spring 201 extends a predetermined distance and passes over the bottom of the supporting leg 104.

[0032] It should be noted that, by providing the spring 201 extending outward, during the above-mentioned hoisting process, the spring 201 first contacts the external contact surface, providing a buffer space for the hoisting personnel to facilitate adjustment of the height and speed of the crane.

[0033] Furthermore, in order to realize the installation of the spring 201 on the supporting foot 104, as shown in FIG. Figure 5 and Figure 6As shown, each of the buffer components 20 also includes a disassembly seat, which is composed of two bow hoops 202. The two bow hoops 202 are symmetrically arranged and connected to each other by bolts located at both ends of the bow hoops 202. The disassembly seat is sleeved on the corresponding supporting foot 104. The spring 201 is arranged in a ring at the bottom of the disassembly seat. The spring 201 is fixedly connected to the disassembly seat, and its fixed connection method includes but is not limited to welding. When the bolts located at both ends of the bow hoop 202 are tightened, the inner hole walls of the two bow hoops 202 fit with the supporting foot 104. When the bolts located at both ends of the bow hoop 202 are unscrewed, the disassembly seat can be removed from the supporting foot 104.

[0034] Furthermore, in order to prevent the disassembly seat from being separated from the supporting foot 104 when the bolts at both ends of the bow hoop 202 are loosened, Figure 5 As shown, each of the supporting legs 104 has a first axial shoulder 1042 at one end facing away from the tank body, and the disassembly seat is located above the first axial shoulder 1042. The maximum radial dimension of the first axial shoulder 1042 is greater than the maximum radial dimension of the inner hole formed when the two bow hoops 202 are connected.

[0035] Furthermore, when the tank is arranged vertically and the springs 201 on the three supporting legs 104 are in contact with the horizontal plane, the springs 201 on the three supporting legs 104 will be compressed due to the heavy weight of the tank, and the supporting legs 104 will be in contact with the horizontal plane. At this time, the buffering effect of the springs 201 is no longer needed. In view of this, Figure 5 As shown, each of the supporting feet 104 has a second axial shoulder 1043 at one end away from the tank body, and the second axial shoulder 1043 is located above the first axial shoulder 1042, and the disassembly seat is located between the first axial shoulder 1042 and the second axial shoulder 1043, and a plurality of upper release members 1044 with external threads are threadedly connected to the second axial shoulder 1043, and one end of the upper release member 1044 passes through the second axial shoulder 1043 and abuts against the disassembly seat.

[0036] It should be noted that when the three supporting legs 104 are in contact with the horizontal plane, the installer can screw the upper release piece 1044 and move the upper release piece 1044 upward along the thread. Then, the disassembly seat moves upward under the elastic force of the spring 201 in the contracted state and abuts against the upper release piece 1044 again. The installer can further screw the upper release piece 1044 and move it upward until the spring 201 is in an uncompressed state.

[0037] Furthermore, since the side foot 101 is provided on one side of the tank body, in order to make the center of the tank body coincide with its central axis when it is lifted vertically, as shown in FIG. Figure 4 As shown, a counterweight 1011 is provided on the side of the tank body away from the side foot 101, and the counterweight 1011 is connected to the tank body, and the connection method includes but is not limited to welding or bolt connection.

[0038] Furthermore, when the three supporting legs 104 are close to the horizontal plane, in order to facilitate the installation personnel to determine the vertical state of the tank body, as shown in FIG. Figure 5 As shown, each of the supporting legs 104 is provided with a leveling bubble 1045 , and the leveling bubble 1045 is fixed to the supporting legs 104 by adhesive connection.

[0039] It is obvious that, compared with the prior art, the present application achieves the advantage of easy lifting by providing the spring 201 , the counterweight block 1011 and the level bubble 1045 .

[0040] In summary, the liquid oxygen storage tank according to the embodiment of the present application is explained, which provides the liquid oxygen storage tank with advantages such as easy transportation and binding, more reasonable load distribution, and easy lifting.

[0041] It is worth mentioning that in the embodiments of the present application, the liquid oxygen storage tank has a simple structure, does not involve complex manufacturing processes and expensive materials, and is highly economical. Furthermore, for manufacturers, the liquid oxygen storage tank provided in the present application is easy to produce and low in cost, which is more conducive to controlling production costs and further facilitating product promotion and use.
