Metal pressure vessels have been widely applied to our actual life and are widely used in various fields such as petroleum, chemical industry, and natural gas.
[0003] However, in some carbonated beverage production workshops, it is inevitable to use some pressure vessels to load carbonated solutions. However, due to the instability of carbonic acid molecules in the carbonated solution, when the container moves, it is inevitable that the internal carbonated solution will shake, causing carbonic acid to decompose into carbon dioxide gas. As the carbon dioxide gas floats upward in the tank, a large amount of gas will accumulate above the liquid level in the tank, leading to an increase in the pressure inside the container, which is likely to cause a great burden on the tank body of the pressure vessel, further increasing the risk of explosion of the pressure vessel, affecting safe production, and posing certain potential safety hazards to the staff.

Specific embodiments
[0023] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it should not be construed as a limitation on the protection scope of the present utility model.
[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution: an explosion-proof metal pressure vessel, including a container body 1. A feed pipe 7 is fixedly connected to the surface of the container body 1. Carbonic acid solution can enter the interior of the container body 1 through the feed pipe 7. An air cylinder 13 is fixedly connected to the surface of the container body 1. The interior of the air cylinder 13 can hold air. A first check valve 8 is fixedly connected to the surface of the air cylinder 13. The first check valve 8 can facilitate the entry of external air into the interior of the air cylinder 13 and prevent the air inside the air cylinder 13 from discharging outward. A second check valve 9 is fixedly connected to the surface of the air cylinder 13. The second check valve 9 can facilitate the discharge of the air inside the air cylinder 13 to the outside and prevent external air from flowing back into the interior of the air cylinder 13. One end of the second check valve 9 away from the air cylinder 13 is fixedly connected to an air pipe 4, facilitating the discharge of the air inside the air cylinder 13 through the air pipe 4 to the outside.
[0025] Two chutes 12 are opened on the inner wall of the container body 1. A sliding plate 5 is slidably connected to the inner walls of the two chutes 12. Under the action of the gas pressure above the interior of the container body 1, the sliding plate 5 can slide on the inner walls of the two chutes 12. The feed pipe 7 penetrates the surface of the sliding plate 5 and is slidably connected to the interior of the sliding plate 5. Two springs 10 are fixedly connected to the surface of the sliding plate 5. One end of each of the two springs 10 away from the sliding plate 5 is fixedly connected to the inner top wall of the container body 1. Under the elastic force of the two springs 10, the position of the sliding plate 5 can be restored. A sealing gasket is provided on the surface of the sliding plate 5 to seal the gap between the sliding plate 5 and the container body 1.
[0026] The surface of the sliding plate 5 is fixedly connected with a piston rod 6. The piston rod 6 penetrates through the surface of the container body 1. One end of the piston rod 6 away from the sliding plate 5 is slidably connected with the inner wall of the air cylinder 13. When the sliding plate 5 slides to drive the piston rod 6 to slide on the inner wall of the air cylinder 13, the piston rod 6 can push the air inside the air cylinder 13, so that the air inside the air cylinder 13 enters the inside of the air pipe 4.
[0027] The surface of the container body 1 is fixedly connected with a stabilizing frame 2. The stabilizing frame 2 can support the container body 1 and facilitate the movement of the container body 1. The surface of the stabilizing frame 2 is fixedly connected with a first condensation box 3. The first condensation box 3 is convenient for recycling the coolant. The surface of the stabilizing frame 2 is fixedly connected with a second condensation box 17. The second condensation box 17 contains the coolant. The surface of the second condensation box 17 is fixedly connected with the air pipe 4. One end of the air pipe 4 away from the second condensation box 17 is fixedly connected with the surface of the check valve II 9. The air inside the air pipe 4 can squeeze the coolant inside the second condensation box 17, so that the coolant inside the second condensation box 17 flows out. The surface of the second condensation box 17 is threadedly connected with a liquid injection bolt 18, which is convenient for injecting the coolant. The surface of the second condensation box 17 is fixedly connected with a return pipe 15. The return pipe 15 is arranged obliquely. One end of the return pipe 15 away from the second condensation box 17 is fixedly connected with the surface of the first condensation box 3. The surface of the return pipe 15 is fixedly connected with a valve 16.
[0028] The surface of the second condensation box 17 is fixedly connected with a cooling pipe 11. One end of the cooling pipe 11 away from the second condensation box 17 is fixedly connected with the surface of the first condensation box 3. The cooling pipe 11 is fixedly connected with the inside of the container body 1. The cooling pipe 11 is spiral. When the coolant inside the second condensation box 17 flows into the inside of the cooling pipe 11, the coolant will flow through the cooling pipe 11 in a circumferential manner and then flow into the inside of the first condensation box 3, so as to realize the cooling and temperature reduction of the container body 1. When the first condensation box 3 is filled with the coolant and the coolant inside the second condensation box 17 is completely discharged, by opening the valve 16, the coolant inside the first condensation box 3 can flow back into the inside of the second condensation box 17 under the action of gravity, so as to realize the reuse of the coolant, save resources and reduce costs.
[0029] Furthermore, when storing the carbonic acid solution, after filling the carbonic acid solution into the interior of the container body 1 through the feed pipe 7, as the container body 1 moves, carbon dioxide in the carbonic acid solution separates from the liquid and floats above the liquid level inside the tank body, resulting in an increase in the air pressure inside the tank body. At this time, the valve 16 is in the closed state, and the pressure of the carbon dioxide gas above the interior of the container body 1 will squeeze the inner wall of the container body 1. Therefore, the gas inside the container body 1 will squeeze the sliding plate 5, causing the sliding plate 5 to slide on the inner walls of the two chutes 12. When the sliding plate 5 is pushed upward by the gas inside the tank body and slides upward, since the distance between the sliding plate 5 and the liquid level inside the tank body increases, a larger volume is provided for the generated high-pressure carbon dioxide gas, preventing the tank body from deforming or even exploding due to excessive air pressure of the carbon dioxide gas inside the tank body, thus ensuring the stability of the tank body, avoiding harm to the staff and even the production workshop due to the explosion of the tank body, maximizing the smooth progress of safe production, improving safety, and at the same time extending the service life of the device, which is worthy of promotion.
[0030] In addition, when the sliding plate 5 slides under the push of air pressure, it will drive the piston rod 6 to move synchronously, and then drive the piston rod 6 to slide inside the air cylinder 13. At this time, the piston rod 6 can squeeze the air inside the air cylinder 13, driving the piston rod 6 to squeeze the air inside the air cylinder 13 into the interior of the air pipe 4. Subsequently, the air inside the air pipe 4 can squeeze the coolant inside the second condensation box 17. Then, the coolant inside the second condensation box 17 flows into the interior of the cooling pipe 11 under the squeeze of air pressure and flows through the entire interior of the cooling pipe 11, and then flows into the interior of the first condensation box 3. During this process, the carbonic acid solution inside the container body 1 can be cooled down, thereby slowing down the speed of carbonic acid separating from the solution, increasing the solubility of carbon dioxide, dissolving the generated carbon dioxide back into the water again, and at the same time, under the squeeze of the upper sliding plate 5 on carbon dioxide, promoting the carbon dioxide to be pressed into the solution again, promoting the re-formation of carbonic acid, thereby causing the pressure inside the container body 1 to drop. Subsequently, when the pressure inside the container body 1 decreases, the sliding plate 5 returns to its original position under the elastic force of the two springs 10, further accelerating the maintenance of the pressure inside the container body 1 at a stable state, preventing the solution inside the tank body from being affected, and ensuring the quality of the carbonic acid solution inside the tank body.
[0031] Working principle: The sliding plate 5 is pushed by air pressure and drives the piston rod 6 to slide inside the air cylinder 13, squeezing the air inside the air cylinder 13 into the inside of the air pipe 4. Subsequently, the air inside the air pipe 4 squeezes the coolant inside the second condensation box 17, causing the coolant to flow into the inside of the cooling pipe 11 to cool the carbonic acid solution inside the container body 1, thereby slowing down the speed at which carbonic acid separates from the solution, and enabling the generated carbon dioxide to redissolve in water and recombine to form carbonic acid again.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the gist of the present invention.
