Description

Technical Field

[0001] This utility model belongs to the field of cryogenic container technology, and in particular relates to a flat-bottomed cryogenic pressure vessel that facilitates the installation of a support mechanism. Background Technology

[0002] Cryogenic pressure vessels are mainly used to store refrigerated liquefied gases (critical temperature below -50℃). Their structure consists of an outer tank, an inner container, and a piping system. Nowadays, the outer tank and the inner container are connected by a support structure to form a stable and reliable overall structure.

[0003] Because the top and bottom of the inner container are both arc-shaped structures with curved outer surfaces, the curved surface makes it difficult to position the bottom support mechanism during installation. This affects the installation efficiency and positional accuracy of the bottom support mechanism. If the angle or position of the bottom support mechanism deviates, it can easily lead to poor support and difficulty in welding, thus affecting the container's performance.

[0004] Therefore, designing a container device that facilitates the precise installation of the base support mechanism is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this utility model is to provide a flat-bottomed cryogenic pressure vessel that facilitates the installation of the support mechanism. Through the design of the bottom support tooling, the installation and positioning of the bottom support mechanism is convenient, ensuring the accuracy of the installation position, improving the positional stability and performance of the inner support mechanism, and the tooling can be quickly removed after the bottom support mechanism is installed for the installation of the next bottom support mechanism, which is convenient and greatly improves the assembly efficiency of the bottom support mechanism.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a flat-bottomed cryogenic pressure vessel that facilitates the installation of a support mechanism. It includes an outer tank, an inner container, and a bottom support fixture. A flat base is fixed to the bottom of the outer tank, and a set of axial support mechanisms and several bottom support mechanisms are fixed between the inner container and the outer tank.

[0008] The bottom support mechanism includes an upper sleeve and a lower sleeve. The bottom end of the lower sleeve is provided with a square base. A first fiberglass support is provided between the upper sleeve and the lower sleeve. An arc-shaped plate is fixed to the top end of the upper sleeve through a transition tube. A through opening is provided on the square base.

[0009] The bottom support fixture includes a set of side edges. Fastening strips and connecting strips are fixed at both ends between the two side edges respectively. A magnetic suction plate with an arc-shaped outer surface is fixed to the outside of the fastening strip. A positioning edge is fixed to the connecting strip by adjusting screws. The positioning edge has an L-shaped structure and fastening screws are provided on the horizontal part. An inner guide edge is provided on the upper part of the inner side of the two side edges. An opening is formed between the end of the inner guide edge and the fastening strip.

[0010] The bottom surfaces of the side, fastening strip, and connecting strip are in contact with the inner bottom surface of the outer can. The fastening strip is fixed to the inner wall of the outer can by a magnetic plate. The square base has a through opening and is slidably disposed between two inner guide edges. The bottom surface of the square base is in contact with the inner bottom surface of the outer can. The side surface of the square base is in contact with the vertical edge of the positioning edge. The square base is fixed to the positioning edge by a through opening and fastening screws. The arc-shaped plate is in contact with the bottom surface of the inner container and welded to it.

[0011] Furthermore, the two axial support mechanisms are respectively located at the top and bottom axial centers of the inner container. The axial support mechanism includes two end caps, with a second fiberglass support between the two end caps and a reinforcing pad at the end of each end cap.

[0012] Furthermore, a set of reinforcing weld grooves is provided at the connection between the lower sleeve and the square base, the bottom of the reinforcing weld grooves extends to the bottom surface of the square base, and the reinforcing weld grooves are misaligned with the through opening.

[0013] Furthermore, the fastening strip has an insertion slot on its outer side, and the magnetic plate is fixed in the insertion slot by fasteners.

[0014] Furthermore, both the fastening screw and the adjusting screw have a throttle at the screw head end, and the throttle has several anti-slip grooves on its circumferential side.

[0015] Furthermore, the distance between the inner guide edge and the bottom surface of the side edge is consistent with the thickness of the square base, and the distance between the two side edges is consistent with the width of the square base.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, through the design of the bottom support fixture, facilitates the installation and positioning of the bottom support mechanism, ensures the accuracy of the installation position, improves the positional stability and performance of the inner support mechanism, and allows for quick removal of the fixture after the bottom support mechanism is installed, making it convenient for the installation of the next bottom support mechanism. This greatly improves the assembly efficiency of the bottom support mechanism. Furthermore, after the last bottom support mechanism is installed, the fixture does not need to be removed; it can be directly placed into the container without affecting the normal use of the container. At the same time, it can be quickly activated when the bottom support mechanism needs maintenance or replacement in the future.

[0018] 2. This utility model uses an arc-shaped magnetic suction plate to fit against the inner wall of the outer can. The design of the positioning edge can control the position of the bottom support mechanism on the bottom support fixture, thereby determining the distance between the bottom support mechanism and the outer can. This allows for precise control of the position of the bottom support mechanism, ensuring that the arc-shaped plate fits tightly against the inner container, which is beneficial for welding and improves positional stability.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
