Description

Technical Field

[0001] The utility model relates to the technical field of liquefied natural gas storage tanks, in particular to a low-temperature storage tank carrying a pump skid. Background Art

[0002] Cryogenic liquefied gas is also called refrigerated liquefied gas or deep frozen gas, and is commonly referred to as cryogenic liquid. Cryogenic liquid has a boiling point below –130°F (–90°C). Cryogenic liquid is used because of its low temperature characteristics or allows large-scale storage or transportation. The scope of this technology patent product includes cryogenic liquids that are processed, stored and sold in liquid form, including liquid argon, liquid helium, liquid hydrogen, liquefied natural gas and liquid nitrogen. With the rapid development of emerging industries such as domestic electronics, machinery manufacturing, optical fiber and fine chemicals, as well as liquefied natural gas energy, the new decentralized retail gas market continues to grow and develop, and the application areas of industrial and energy gas are gradually penetrating from the bulk centralized gas market to the emerging decentralized gas market, becoming one of the future development trends.

[0003] At present, conventional cryogenic storage tanks are separate products, with no connection except for the connection between the pipeline and the submersible pump skid during on-site installation. During installation, the gas station needs to fix the storage tank, then fix the pump skid, and finally connect the pipeline between the storage tank and the pump skid on-site, which not only occupies a large area, but also has a large workload on-site and a high investment cost. To this end, we provide a cryogenic storage tank with a pump skid to solve the above problems. Utility Model Content

[0013] 3) Beneficial effects:

[0014] Compared with the prior art, the cryogenic storage tank with pump skid has the following beneficial effects:

[0015] 1. The utility model designs the pump skid storage tank, mounting frame and submersible pump skid as an integral structure, and installs them on the mounting frame in a detachable manner, which greatly reduces the workload of separately fixing the storage tank and pump skid and connecting pipelines on site. This integrated design simplifies the installation process, shortens the installation time, and reduces the difficulty of construction.

[0016] 2. The utility model has a compact integrated design, which effectively saves space. At the same time, since on-site operations and material usage are reduced, the investment cost is correspondingly reduced. The pump skid storage tank and the submersible pump skid are connected by supporting assemblies.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-6 As shown, the utility model provides a technical solution: a low-temperature storage tank carrying a pump skid, comprising a pump skid storage tank 1, a mounting frame 2 and a submersible pump skid 5, a pressure gauge 10 is installed on the pump skid storage tank 1, two lifting blocks 11 are fixedly connected to the top of the pump skid storage tank 1, and lifting holes 12 are opened on the two lifting blocks 11.

[0026] The pump skid storage tank 1 is made of stainless steel. When installing the pump skid storage tank 1, the hook can lift the pump skid storage tank 1 through the lifting block 11 and the lifting hole 12, thereby completing the lifting of the pump skid storage tank 1. The pressure gauge 10 can monitor the air pressure of the liquefied gas in the pump skid storage tank 1 in real time and display the pressure value through the dial.

[0027] A support assembly is provided between the pump skid storage tank 1 and the mounting frame 2 , and the pump skid storage tank 1 and the submersible pump skid 5 support assembly can be detachably mounted on the mounting frame 2 .

[0028] The support assembly includes a support leg 3 fixedly connected to the pump skid tank 1, the bottom end of the support leg 3 is fixedly connected to a first fixing plate 4, the first fixing plate 4 is fixedly connected to the mounting frame 2, and the first fixing plate 4 is located below the mounting frame 2. The first fixing plate 4 and the pump skid tank 1 are made of the same material. The pump skid tank 1 can be supported by the support leg 3 and the first fixing plate 4, so that a space for installing a submersible pump skid 5 is left between the pump skid tank 1 and the mounting frame 2.

[0029] Since the supporting legs 3 prop up the pump skid storage tank 1 on the mounting frame 2, the pump skid storage tank 1 is at a certain distance from the ground, which makes it unnecessary to build a higher ground foundation and can reduce civil engineering costs.

[0030] The support assembly also includes a second fixed plate 6 installed on the mounting frame 2, and the second fixed plate 6 is located below the mounting frame 2. The bottom end of the submersible pump skid 5 is installed on the second fixed plate 6. The submersible pump skid 5 is installed on the mounting frame 2 through the second fixed plate 6. This allows the pump skid storage tank 1 and the submersible pump skid 5 to be installed together on the mounting frame 2. The overall footprint is reduced, and the size of the gas station cofferdam does not need to be too large, which also saves civil engineering investment.

[0031] Since the first fixing plate 4 and the second fixing plate 6 are both located below the mounting frame 2, the first fixing plate 4 and the second fixing plate 6 can be embedded in the foundation or directly connected to bolts embedded in the foundation during the construction of the concrete foundation.

[0032] An instrument box 9 is installed on the mounting frame 2, and a submersible pump skid 5 and a connecting pipeline 7 are arranged between the pump skid storage tank 1 and the mounting frame 2. The two ends of the connecting pipeline 7 are respectively fixedly connected to the pump skid storage tank 1 and the submersible pump skid 5, and a liquid outlet pipeline 8 is installed at the output end of the submersible pump skid 5. During production, the two ends of the connecting pipeline 7 are directly installed on the pump skid storage tank 1 and the submersible pump skid 5, respectively. There is no need to reinstall the pump skid structure formed by the submersible pump skid 5 and the pump skid storage tank 1 on site, so the workload of on-site installation is greatly reduced, and there is no need to make an operating platform, thereby reducing investment costs.

[0033] It should be noted that, in this article, the orientation or position relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model; the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
