Description

Technical Field

[0001] The utility model belongs to the technical field of gas storage, and in particular relates to a liquid carbon dioxide storage tank. Background Art

[0002] Carbon dioxide, a gaseous compound with the chemical formula CO2, is one of the main components of the air and a common greenhouse gas. At room temperature, carbon dioxide is a colorless, odorless, non-flammable gas with a density greater than that of air. It is slightly soluble in water and is an anhydride of carbonic acid. It can react with water to form carbonic acid. Under high pressure and low temperature, carbon dioxide gas is liquefied into liquid form. Liquid carbon dioxide is a refrigerant that can be used to preserve food and for artificial rainfall. It is also an industrial raw material that can be used to make soda ash, urea and soft drinks. Carbon dioxide is usually stored in storage tanks.

[0003] Most of the current liquid carbon dioxide storage tanks do not have leak detection functions, resulting in the inability to detect leaks in liquid carbon dioxide storage tanks in a timely manner, which in turn causes waste of resources, environmental pollution and even safety hazards. Liquid carbon dioxide may quickly vaporize when leaking, causing increased carbon dioxide concentration in local areas, posing a risk of suffocation to workers. Due to the lack of leak detection functions, workers may need to conduct manual inspections regularly to confirm the sealing and integrity of the storage tanks. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 4 As shown, an embodiment of the utility model provides a liquid carbon dioxide storage tank, comprising a tank body 1, a mounting base 2 is provided below the tank body 1, a limiting frame 3 is fixed inside the mounting base 2, and the tank body 1 is slidably connected to the inner wall of the limiting frame 3. Vertical plates 4 are fixed on the left and right sides of the back of the mounting base 2, and a positioning frame 5 is slidably connected above the front side of the vertical plate 4. A groove 6 is provided on the surface of the positioning frame 5, and a mounting shell 7 is fixed to the rear side of the mounting base 2. A movable structure 8 is movably connected to the inside of the mounting shell 7, a connecting block 9 is fixed to the front side of the movable structure 8, and a detection cover 10 is fixed to the front side of the connecting block 9. The detection cover 10 is sleeved on the surface of the tank body 1 and slidably connected to the tank body 1. A carbon dioxide sensor 11 is fixed to the front side of the detection cover 10, and the sensing head of the carbon dioxide sensor 11 passes through the detection cover 10 and extends to the interior of the detection cover 10.

[0023] See also Figures 1 to 4 As shown, the movable structure 8 specifically includes a drive motor 81, a screw rod 82 and a movable block 83. The drive motor 81 is fixed to the top of the mounting shell 7, and the screw rod 82 is rotatably connected to the inside of the mounting shell 7. The output shaft of the drive motor 81 passes through the mounting shell 7 and is fixedly connected to the top of the screw rod 82. The movable block 83 is slidably connected to the bottom of the interior of the mounting shell 7. The screw rod 82 passes through the movable block 83 and is threadedly connected to the movable block 83. The rear side of the connecting block 9 is fixedly connected to the front side of the movable block 83. The left and right sides of the mounting shell 7 are both provided with limit slots 12. The left and right sides of the movable block 83 are both fixed with limit blocks 13. The limit blocks 13 are located inside the limit slots 12 and are slidably connected to the inner wall of the limit slots 12.

[0024] When the upper drive motor 81 is turned on, the output shaft of the drive motor 81 drives the screw rod 82 to rotate, and the limit blocks 13 on both sides will slide inside the limit groove 12, so that the moving block 83 can only move up and down on the surface of the screw rod 82, and drive the detection cover 10 to move up and down through the connecting block 9, so that the detection cover 10 can regularly detect the surface of the tank body 1.

[0025] See also Figures 1 to 4 As shown, sealing strips 14 are bonded to the upper and lower sides of the inner wall of the detection cover 10. The material of the sealing strip 14 is rubber. One side of the sealing strip 14 is in contact with the surface of the tank body 1. The provision of the sealing strip 14 can improve the sealing effect of the detection cover 10. If a leak occurs on the surface of the tank body 1, the carbon dioxide sensor 11 can quickly sense the carbon dioxide so as to notify the staff. A warning light 15 is fixed to the front side of the mounting base 2. The warning light 15 is used in conjunction with the carbon dioxide sensor 11. When the carbon dioxide sensor 11 detects a leak in the tank body 1, the warning light 15 on the front side of the mounting base 2 will turn on, thereby alerting the surrounding staff.

[0026] See also Figures 1 to 4 As shown, a slide groove 16 is provided on the surface of the vertical plate 4, and sliders 17 are fixed on the left and right sides of the back of the positioning frame 5. The sliders 17 are located inside the slide groove 16 and are slidably connected to the inner wall of the slide groove 16. The positioning frame 5 can slide up and down on the surface of the vertical plate 4. When the staff needs to take the tank body 1, they can pull the positioning frame 5 to make the positioning frame 5 away from the tank body 1, and then the tank body 1 can be removed from the mounting seat 2.

[0027] The specific working principle of the present invention is as follows: when the storage tank is stored, the drive motor 81 on the rear side will be turned on periodically, and the connecting block 9 will drive the detection cover 10 to move slowly on the surface of the tank body 1. At this time, the carbon dioxide sensor 11 will detect the area covered by the detection cover 10. If carbon dioxide leakage is found in a certain area of ​​the tank body 1, the drive motor 81 will be immediately turned off, so that the detection cover 10 stays in the corresponding area of ​​the tank body 1, and the warning light 15 below will be turned on, thereby reminding the staff to deal with the leakage area of ​​the tank body 1.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
