Description

Technical Field

[0001] This utility model relates to the field of carbon dioxide storage tank technology, specifically to a low-temperature carbon dioxide storage device. Background Technology

[0002] Gaseous carbon dioxide transforms into a liquid state under high pressure and low temperature conditions. Liquid carbon dioxide is easy to transport and store, and is widely used in food and beverage production, healthcare, machinery manufacturing, and the chemical industry. Liquid carbon dioxide is typically stored in cryogenic storage tanks, which consist of an outer tank and an inner tank for storing the carbon dioxide.

[0003] For example, Chinese patent application CN202323304710.7 discloses a liquid carbon dioxide storage tank, which specifically includes an outer storage tank and an inner storage tank. Connecting components are provided at the top and bottom of the inner storage tank to fix it. Each connecting component includes two fixing blocks, which are respectively fixedly connected to the top and bottom of the inner storage tank. A second spring is provided between the bottom of the fixing blocks and the bottom of the inner wall of the outer storage tank. By utilizing the fixing blocks and the second spring, the inner storage tank can be buffered, providing some protection when the outer storage tank vibrates due to unstable external environment. However, it also has the following technical problems:

[0004] Because of the springs installed at both ends of the inner storage tank, the inner storage tank inside the outer storage tank is prone to shaking due to instability during transportation, which increases the internal pressure of the inner storage tank and may cause carbon dioxide leakage. Utility Model Content

[0005] Therefore, this utility model provides a low-temperature carbon dioxide storage device to solve the problem of instability of carbon dioxide storage tanks during transportation in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cryogenic carbon dioxide storage device includes an inner tank for storing carbon dioxide.

[0008] An outer tank is installed on the outside of the inner tank. A support base for supporting the inner tank is installed inside the outer tank. A damper for buffering the inner tank is installed in the middle of the support base. A spring for damping the inner tank is sleeved on the outside of the damper.

[0009] The lower end of the inner tank is equipped with a base, and the support base includes a fixing plate and an airbag for locking the inner tank in conjunction with the base.

[0010] Furthermore, the support base has a mounting groove in the middle, a connecting groove at the lower end of the middle of the mounting groove, and a plurality of limiting grooves for limiting the base at the upper end of the connecting groove.

[0011] Furthermore, a buffer pad is installed inside the cavity of the mounting groove, a connecting rod for supporting the fixing plate is installed at the lower end of the fixing plate, a hose is connected to the lower end of the airbag, a straight pipe is connected to the lower end of the hose, and a valve is installed in the middle of the straight pipe.

[0012] Furthermore, the base has multiple sliders installed on its side for sliding within the limiting groove, a connecting cylinder for limiting the airbag is installed at the lower center of the base, and a bottom cover for limiting the airbag is installed at the lower end of the connecting cylinder.

[0013] Furthermore, the fixing plate is located at the upper end of the inner cavity of the connecting cylinder, and the airbag is located at the lower end of the inner cavity of the connecting cylinder.

[0014] This utility model has the following advantages:

[0015] When transporting the outer tank, the valve is opened to release some of the gas inside the airbag, causing multiple dampers and springs to lift the inner tank. During transportation, the dampers and springs dampen the inner tank, preventing the inner tank from becoming too shaky and increasing its internal pressure. When the outer tank is installed in the working environment, an external air pump inflates the airbag, causing it to expand and press down on the bottom cover, moving the inner tank to the top of the buffer pad. The buffer pad and airbag then cushion the inner tank, providing protection against vibrations in the working environment. Attached Figure Description

[0024] Please see Figures 1-3 This utility model provides a low-temperature carbon dioxide storage device, including an inner tank 20 for storing carbon dioxide.

[0025] An outer tank 10 is installed on the outside of the inner tank 20. A support base 100 for supporting the inner tank 20 is fixedly installed at the bottom of the inner cavity of the outer tank 10. An installation groove 110 is opened in the middle of the support base 100. A buffer pad 150 is installed in the groove of the installation groove 110. The inner tank 20 is placed in the installation groove 110 and is located at the upper end of the buffer pad 150, so that if the external environment vibrates when the outer tank 10 is statically placed, it can buffer the inner tank 20.

[0026] A connecting groove 111 is provided at the lower middle part of the mounting groove 110. A base 200 is fixedly installed at the lower end of the inner tank 20, and a plurality of limiting grooves 112 for limiting the base 200 are provided at the upper end of the connecting groove 111. A plurality of sliders 210 for sliding in the limiting grooves 112 are installed on the edge of the base 200, so that the outer tank 10 is not prone to positional displacement during transportation.

[0027] The support base 100 includes a fixing plate 130 and an airbag 140 for locking the inner tank 20 with the base 200. The lower end of the fixing plate 130 is equipped with a connecting rod 131 for supporting the fixing plate 130. The lower end of the airbag 140 is connected to a hose 141, the lower end of the hose 141 is connected to a straight pipe 142, and a valve 143 is installed in the middle of the straight pipe 142.

[0028] After the outer tank 10 is installed in the working area, it is connected to the output end of the external structural air pump and the straight pipe 142. When the valve 143 is opened, the air pump works and delivers gas into the airbag 140 through the straight pipe 142 and the hose 141. The airbag 140 inflates, causing the connecting cylinder 220 to move downward. The top of the inner cavity of the fixing plate 130 and the connecting cylinder 220 abuts against each other, and the bottom of the inner tank 20 is on the buffer pad 150. Then the valve 143 is closed, so that the inner tank 20 is firmly placed in the mounting groove 110. By setting the airbag 140, not only is the inner tank 20 limited in the mounting groove 110, but when the external environment of the outer tank 10 vibrates, the airbag 140 is also used to buffer the inner tank 20 and prevent the inner tank 20 from shaking too much.

[0029] Multiple dampers 120 for cushioning the inner tank 20 are installed in the middle of the support base 100. Springs 121, which work in conjunction with the dampers 120 to reduce vibration in the inner tank 20, are fitted around the outside of each damper 120. During transport of the outer tank 10, valve 143 is opened to release some of the gas inside the air bladder 140, causing the multiple dampers 120 and springs 121 to lift the inner tank 20. During transport, the dampers 120 and springs 121 dampen the inner tank 20, preventing increased internal pressure due to shaking during transport.

[0030] A connecting cylinder 220 for limiting the airbag 140 is fixedly installed at the lower middle part of the base 200, and a fixing plate 130 is located at the upper end of the inner cavity of the connecting cylinder 220. The airbag 140 is located at the lower end of the inner cavity of the connecting cylinder 220. A bottom cover 221 for limiting the airbag 140 is installed at the lower end of the connecting cylinder 220. The lower end of the airbag 140 and the upper end of the bottom cover 221 abut against each other. When the airbag 140 inflates, the upper end of the airbag 140 abuts against the upper end of the fixing plate 130. The fixing plate 130 is located in the inner cavity of the connecting cylinder 220 to effectively limit the vertical movement distance of the support 100.

[0031] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
