Description

Technical Field

[0001] This utility model relates to the field of vacuum cryogenic storage tank technology, specifically a highly insulating vacuum cryogenic storage tank. Background Technology

[0002] A vacuum cryogenic storage tank is a vertical or horizontal double-layered vacuum insulated storage tank. Its structure mainly consists of an inner tank and an outer tank, with insulation materials such as perlite or aluminum foil and insulation cotton filling the middle. The tank is also evacuated to reduce heat transfer. The inner tank is usually made of thin cryogenic steel plate, which has liquid tightness and flexibility and is used to directly store cryogenic liquids.

[0003] For example, the authorized patent with announcement number CN215174168U (a high-insulation vacuum cryogenic storage tank) includes an inner tank, a first cylinder installed on the outside of the inner tank and fixedly connected to the inner tank, a second cylinder installed on the outside of the first cylinder, a vacuum cavity between the first cylinder and the second cylinder, perlite filling the space between the first cylinder and the second cylinder, a polypropylene carbon fiber composite shell installed on the outside of the second cylinder and connected to the second cylinder by a connecting column, and a reflective heat insulation film provided on the outside of the polypropylene carbon fiber composite shell and fixedly connected to the polypropylene carbon fiber composite shell.

[0004] While the aforementioned existing technologies can improve thermal insulation, they rely on individual damping springs for shock absorption. However, these springs generate rebound force when stressed, affecting the stability of the tank. Consequently, traditional vacuum cryogenic storage tanks generally have poor shock absorption performance, which is detrimental to the long-term stable use of the tank. Therefore, there is an urgent market need to develop a high-insulation vacuum cryogenic storage tank to help people solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to provide a highly insulating vacuum cryogenic storage tank to solve the problem mentioned in the background art that most traditional vacuum cryogenic storage tanks have poor shock absorption performance, which is not conducive to the long-term stable use of the tank.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a highly insulated vacuum cryogenic storage tank, comprising a tank body, with support plates symmetrically fixedly installed on both sides below the tank body, a shock-absorbing seat disposed below the support plates, and a cement base disposed below the shock-absorbing seat. The shock-absorbing seat includes a shock-absorbing plate and a shock-absorbing box. The shock-absorbing plate is disposed above the shock-absorbing box and fixedly connected to the support plates. The shock-absorbing box has an opening at the top, and the lower end of the shock-absorbing plate extends into the interior of the shock-absorbing box. Multiple shock-absorbing components are disposed at the lower part of the interior of the shock-absorbing box. Each shock-absorbing component includes an upper plate, a shock-absorbing rubber block, and a lower plate. The upper plate is fixedly installed above the shock-absorbing rubber block, and the lower plate is fixedly installed below the shock-absorbing rubber block. The upper plate is fixedly connected to the shock-absorbing plate, and the lower plate is fixedly connected to the shock-absorbing box. A damping rod is disposed between two adjacent shock-absorbing components. The lower end of the damping rod is fixedly connected to the shock-absorbing box, and the upper end of the damping rod is fixedly connected to the shock-absorbing plate.

[0007] Preferably, the shock-absorbing rubber block has an inner hole, and a compression spring is installed inside the inner hole of the shock-absorbing rubber block. The upper end of the compression spring is fixedly connected to the upper plate, and the lower end of the compression spring is fixedly connected to the lower plate.

[0008] Preferably, the compression spring has a guide post inside, the upper end of the guide post is fixedly connected to the upper plate, and the lower end of the guide post slides through the lower plate.

[0009] Preferably, bottom holes are symmetrically arranged on both sides below the shock absorber box, and side grooves are symmetrically arranged on both sides inside the shock absorber box. Limiting blocks are arranged inside the side grooves, and the limiting blocks are fixedly connected to the shock absorber plate.

[0010] Preferably, the tank body includes an inner tank and a composite outer shell, wherein the composite outer shell is disposed on the outside of the inner tank.

[0011] Preferably, the composite shell includes a first shell body and a second shell body, with a cavity provided between the first shell body and the second shell body, the cavity being filled with pearlescent sand, and both the first shell body and the second shell body being made of polypropylene carbon fiber composite material.

[0012] Preferably, the outer shell is provided with a reflective film, and an anti-corrosion layer is provided on the outer side of the reflective film.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model forms a composite shock absorption structure by setting shock absorbers and damping rods. When shock absorption occurs, the shock absorber rubber block absorbs vibration energy through elastic deformation, while the damping rod effectively suppresses the rebound force and reduces vibration transmission. This design can not only quickly attenuate vibration, but also avoid the influence of spring rebound force on the stability of the tank, ensuring that the tank remains stable during transportation and use, improving the shock absorption performance of the vacuum cryogenic storage tank and increasing the stability of use.

[0015] (2) The utility model provides additional support and restoring force for the shock absorption structure by setting the compression spring, and further optimizes the shock absorption performance by the synergistic effect of the compression spring and the shock absorption rubber block, thereby improving the stability of the vacuum cryogenic storage tank in the face of complex vibration environment and increasing its practicality.

[0016] (3) The present invention is made by filling the interior of the composite shell with perlite and using polypropylene carbon fiber composite material. Perlite, as a high-efficiency heat insulation material, effectively reduces the rate of temperature loss inside the tank and ensures the constant low temperature environment. Polypropylene carbon fiber composite material, with its lightweight, high strength and corrosion resistance, enhances the overall structural strength and durability of the tank, thereby improving the high heat insulation capacity of the vacuum low temperature storage tank.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 This utility model provides an embodiment of a highly insulated vacuum cryogenic storage tank, comprising a tank body 1, with support plates 2 symmetrically fixedly installed on both sides below the tank body 1. A shock-absorbing seat 3 is provided below the support plates 2, and a cement base 4 is provided below the shock-absorbing seat 3. The shock-absorbing seat 3 includes a shock-absorbing plate 301 and a shock-absorbing box 302. The shock-absorbing plate 301 is disposed above the shock-absorbing box 302 and fixedly connected to the support plates 2. The shock-absorbing box 302 has an opening at the top, and the lower end of the shock-absorbing plate 301 extends into the interior of the shock-absorbing box 302. The device is equipped with multiple damping components 6, each including an upper plate 601, a damping rubber block 602, and a lower plate 603. The upper plate 601 is fixedly installed above the damping rubber block 602, and the lower plate 603 is fixedly installed below the damping rubber block 602. The upper plate 601 is fixedly connected to the damping plate 301, and the lower plate 603 is fixedly connected to the damping box 302. A damping rod 7 is provided between two adjacent damping components 6. The lower end of the damping rod 7 is fixedly connected to the damping box 302, and the upper end of the damping rod 7 is fixedly connected to the damping plate 301. The damping rod 7 is a hydraulic damping rod.

[0024] The composite damping structure, which includes a combination of damping rubber block 602 and damping rod 7, is adopted. The damping rubber block 602 absorbs vibration energy through elastic deformation, while the damping rod 7 effectively suppresses rebound force and reduces vibration transmission. This design can not only quickly attenuate vibration, but also avoid the impact of spring rebound force on the stability of the tank, ensuring that the tank remains stable during transportation and use, improving the damping performance of the vacuum cryogenic storage tank and increasing its stability in use.

[0025] Please see Figure 3 The shock-absorbing rubber block 602 has an inner hole, and a compression spring 8 is installed inside the inner hole of the shock-absorbing rubber block 602. The upper end of the compression spring 8 is fixedly connected to the upper plate 601, and the lower end of the compression spring 8 is fixedly connected to the lower plate 603.

[0026] The inclusion of a compression spring 8 inside the shock-absorbing rubber block 602 enhances the adaptability and durability of the shock-absorbing structure compared to a single shock-absorbing rubber block. The compression spring 8 provides additional support and restoring force to the shock-absorbing structure, making the shock absorption effect more significant and durable. At the same time, the synergistic effect of the compression spring 8 and the shock-absorbing rubber block 602 further optimizes the shock absorption performance and improves the stability of the vacuum cryogenic storage tank when facing complex vibration environments.

[0027] Please see Figure 3The compression spring 8 has a guide post 9 inside. The upper end of the guide post 9 is fixedly connected to the upper plate 601, and the lower end of the guide post 9 slides through the lower plate 603.

[0028] The guide post 9 ensures the vertical movement of the compression spring 8 during the force process, avoiding the reduction of shock absorption effect caused by spring tilting or twisting. In addition, the guide post 9 also enhances the overall structural stability of the shock absorber 6 and increases its practicality.

[0029] Please see Figure 2 The shock absorber box 302 has bottom holes 3021 symmetrically arranged on both sides below it, and side grooves 3022 symmetrically arranged on both sides inside the shock absorber box 302. Limiting blocks 5 are arranged inside the side grooves 3022, and the limiting blocks 5 are fixedly connected to the shock absorber plate 301.

[0030] The side groove 3022 and the limiting block 5 restrict the movement of the shock absorber 301 in the horizontal direction, further ensuring the stability of the tank 1 under vibration.

[0031] Please see Figure 4 The tank body 1 includes an inner tank 101 and a composite outer shell 102. The composite outer shell 102 is disposed on the outside of the inner tank 101. The composite outer shell 102 includes an outer shell body one 1021 and an outer shell body two 1023. A cavity 1022 is provided between the outer shell body one 1021 and the outer shell body two 1023. The cavity 1022 is filled with perlite. Both the outer shell body one 1021 and the outer shell body two 1023 are made of polypropylene carbon fiber composite material.

[0032] The tank 1 is composed of an inner tank 101 and a composite outer shell 102. The composite outer shell 102 is filled with perlite and made of polypropylene carbon fiber composite material, which improves the thermal insulation performance and structural strength of the storage tank. Perlite, as a high-efficiency thermal insulation material, effectively reduces the rate of temperature loss inside the tank and ensures a constant low-temperature environment. Polypropylene carbon fiber composite material, with its lightweight, high strength and corrosion resistance, enhances the overall structural strength and durability of the tank, thereby improving the high thermal insulation capacity of the vacuum cryogenic storage tank.

[0033] Please see Figure 4 The outer shell 1023 is provided with a reflective film, and an anti-corrosion layer 1024 is provided on the outside of the reflective film. The anti-corrosion layer 1024 is a transparent inorganic silicate coating layer.

[0034] The reflective film effectively reflects external heat, reducing the rise in internal temperature of the tank and thus maintaining a stable low-temperature environment. The anti-corrosion layer 1024 uses a transparent inorganic silicate coating layer, which has excellent anti-corrosion performance, can resist the erosion of various chemicals, and extends the service life of the tank.

[0035] Working principle: During use, the vacuum cryogenic storage tank absorbs vibration energy through the elastic deformation of the shock-absorbing rubber block 602, while the damping rod 7 effectively suppresses rebound force and reduces vibration transmission. The compression spring 8 further enhances the shock absorption effect and provides additional support and restoring force. The guide column 9 ensures that the spring moves vertically during the force process, avoiding tilting or twisting, improving shock absorption stability, and ensuring that the tank remains stable during use. At the same time, the tank body 1 adopts an inner tank 101 and a composite outer shell 102 design. The composite outer shell 102 includes outer shell 1021 and outer shell 2 1023, with perlite filling between them to form a high-efficiency heat insulation layer, reducing heat conduction and heat convection. A reflective film and an anti-corrosion layer 1024 are set on the outside of outer shell 2 1023. The reflective film reduces the absorption of external heat, and the anti-corrosion layer 1024 uses a transparent inorganic silicate coating to enhance corrosion resistance, enabling the vacuum cryogenic storage tank to be used stably.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
