AI Technical Summary
Rapid cooling causes a sharp drop in gas pressure inside the container, resulting in a sudden increase in the pressure difference between the inside and outside. This leads to the container being subjected to enormous external pressure, posing a risk of collapse. Furthermore, it damages the container's material structure, reduces its load-bearing capacity, and increases the risk of explosion.
A pressure vessel comprising a tank body, a cover body, an adjustment unit, and a cooling unit is designed. The adjustment unit achieves internal and external pressure balance through a vent plug, a gear mechanism, and an auxiliary plug. The cooling unit utilizes a circulating cooling pipe and a motor-driven worm gear mechanism for rapid cooling.
During rapid cooling, internal and external pressure balance is achieved through a vent plug and gear mechanism to prevent container collapse, protect the container structure, and reduce the risk of explosion. At the same time, rapid cooling is achieved through circulating cooling pipes to ensure safety and stability.

Abstract
Description
Technical Field
[0001] This invention relates to the field of pressure vessel technology, specifically to a pressure vessel that can be rapidly cooled. Background Technology
[0002] Pressure vessels are sealed devices that can withstand a certain pressure. They are used to store and transport gases or liquids, or as containers for chemical reactions, heat exchange, etc. They play a key role in many industrial fields such as chemical, petroleum, energy, and pharmaceutical, ensuring the safe and efficient operation of production processes.
[0003] Under current technology, rapid cooling of pressure vessels can lead to numerous pressure-related hazards. Rapid cooling causes a sharp drop in gas pressure inside the vessel, resulting in a sudden increase in the pressure difference between the inside and outside, subjecting the vessel to enormous external pressure and posing a risk of collapse. Moreover, rapid pressure changes can damage the internal structure of the vessel material, reducing its toughness and increasing its brittleness, thus significantly weakening the vessel's load-bearing capacity. This not only affects the normal use of the pressure vessel but also significantly increases the likelihood of serious safety accidents such as explosions, seriously threatening production safety and the safety of personnel and property. Therefore, we propose a pressure vessel that can be rapidly cooled. Summary of the Invention

[0010] In some embodiments, the auxiliary component further includes a connecting box fixedly connected to the lid body. A first auxiliary tube is fixedly connected to the top of the connecting box, and a second auxiliary tube is fixedly connected to the bottom of the connecting box. Both the first and second auxiliary tubes are in communication with the connecting box. The first auxiliary tube extends out of the lid body, and the second auxiliary tube extends into the can body. The auxiliary plug is slidably and sealingly connected to the connecting box.
[0011] In some embodiments, the regulating unit is configured as two sets, the two sets of regulating units are arranged opposite to each other, and a cooling unit is provided inside the tank.
[0012] In some embodiments, the cooling unit includes a temperature-conducting tank fixedly connected to the tank body, the temperature-conducting tank being fitted with a circulating cooling pipe, both ends of the circulating cooling pipe extending out of the tank body.

[0015] This invention has at least the following beneficial effects: 1. When the tank is rapidly cooled, the gas pressure inside the tank drops sharply, which will cause the vent plug to move downward. The downward movement of the vent plug can reduce the internal space, thereby adapting to and relieving the internal pressure of the tank. 2. When the internal pressure continues to drop, it will drive the vent plug and rod to move downward until the first toothed plate touches the top of the cylinder. At the same time, the first toothed plate will drive the first gear to rotate as it descends, and then drive the auxiliary plug to move outward from the connecting box, thereby connecting the first auxiliary pipe and the second auxiliary pipe. At this time, the tank is connected to the outside, and the internal and external pressure can be balanced. 3. When the internal pressure increases suddenly, the vent plug will continue to rise and leak out of the vent hole. At this time, the gas will enter the empty slot through the vent hole and then be output to the outside of the device through the vent pipe. The vent plug will return to its original position and block the vent hole after the internal and external pressures are balanced. Attached Figure Description

Detailed Implementation
[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Example 1
[0020] Please see Figures 1-8 The present invention provides a technical solution: A pressure vessel for rapid cooling includes a tank body 1, a cover 2 rotatably connected to the top of the tank body 1, connecting plates 3 fixedly connected to the outer sides of both the cover 2 and the tank body 1, a fixing screw 4 threaded between the two connecting plates 3, and sealing rings 5 fixedly connected to the bottom of the cover 2 and the top of the tank body 1. By setting the sealing rings 5, the sealing effect can be guaranteed. like Figure 1 As shown, further, rotating the fixing screw 4 can fix the cover 2 and the tank 1 in place; Adjustment unit 6 is disposed inside cover 2. Adjustment unit 6 includes main body 7, in which air vent plug 703 is disposed. Adjustment unit 6 also includes auxiliary body 8, in which auxiliary plug 811 is disposed.
[0021] The main body 7 includes a cylindrical body 701 fixedly connected inside the cover body 2. A slot 702 is provided inside the cylindrical body 701. The bottom of the cylindrical body 701 extends out of the cover body 2. A vent plug 703 is slidably connected inside the cylindrical body 701. A rod 704 is fixedly connected to the top of the vent plug 703. A fixing ring 705 is fixedly connected inside the cylindrical body 701. The top of the rod 704 passes through the fixing ring 705 and the top of the cylindrical body 701. A spring 706 is sleeved on the rod 704. like Figure 3 As shown, further, by setting a spring 706, when the vent plug 703 descends, it will simultaneously drive the spring 706 to stretch. The spring 706 can provide elasticity, which makes it easy for the vent plug 703 to return to its original position, while also increasing the force to avoid damage caused by mistakes. At the same time, the top of the cylinder 701 can be removed, and springs 706 with different elasticities can be replaced. The main body 7 also includes a vent pipe 707 fixedly connected to the top of the cylinder 701. The vent pipe 707 is connected to the empty groove 702. Multiple vent holes 708 are opened on the inner wall of the cylinder 701. All multiple vent holes 708 are connected to the empty groove 702. like Figure 3 As shown, when the tank 1 is rapidly cooled, the gas pressure inside the tank 1 drops sharply, which will cause the vent plug 703 to move downward. The downward movement of the vent plug 703 can reduce the internal space, thereby adapting to and relieving the internal pressure of the tank 1. The top of the spring 706 is fixedly connected to the retaining ring 705, and the bottom of the spring 706 is fixedly connected to the vent plug 703. The auxiliary component 8 includes a first toothed plate 801 fixedly connected to the top of the rod 704, a frame 802 provided outside the first toothed plate 801, a mounting bracket 803 fixedly connected to the top of the frame 802, the top of the mounting bracket 803 fixedly connected to the top of the inner part of the cover 2, a first gear 804 rotatably connected inside the frame 802, the first gear 804 meshing with the first toothed plate 801, a second gear 805 rotatably connected inside the frame 802, the second gear 805 meshing with the first gear 804, a first bevel gear 806 fixedly connected to one side of the second gear 805, a third gear 807 rotatably connected inside the frame 802, a second bevel gear 808 fixedly connected to one side of the third gear 807, the first bevel gear 806 and the second bevel gear 808 meshing, a second toothed plate 809 slidably connected to the bottom of the frame 802, a connecting rod 810 fixedly connected to one end of the second toothed plate 809, and an auxiliary plug 811 fixedly connected to one end of the connecting rod 810. The auxiliary component 8 also includes a connecting box 812 fixedly connected inside the cover 2. A first auxiliary tube 813 is fixedly connected to the top of the connecting box 812, and a second auxiliary tube 814 is fixedly connected to the bottom of the connecting box 812. Both the first auxiliary tube 813 and the second auxiliary tube 814 are connected to the connecting box 812. The first auxiliary tube 813 extends out of the cover 2, and the second auxiliary tube 814 extends into the tank 1. The auxiliary plug 811 is slidably and sealingly connected to the connecting box 812. like Figure 4 and Figure 5 As shown, when the internal pressure continues to drop, it will drive the vent plug 703 and the rod 704 to move downward until the first toothed plate 801 abuts against the top of the cylinder 701. At the same time, the descent of the first toothed plate 801 will drive the first gear 804 to rotate, and then drive the auxiliary plug 811 to move outward from the connecting box 812, thereby connecting the first auxiliary pipe 813 and the second auxiliary pipe 814. At this time, the tank 1 is connected to the outside, and the internal and external pressure can be balanced. The regulating unit 6 is set in two sets, and the two sets of regulating units 6 are arranged opposite to each other. A cooling unit 9 is installed inside the tank body 1. The cooling unit 9 includes a temperature-conducting tank 901 fixedly connected inside the tank body 1. The temperature-conducting tank 901 is covered with a circulating cooling pipe 902, and both ends of the circulating cooling pipe 902 extend out of the tank body 1. The cooling unit 9 also includes an inner tank 903 disposed inside the temperature conducting tank 901. A rotating shaft 904 is fixedly connected to the bottom of the inner tank 903. A chassis 905 is rotatably connected to the bottom of the rotating shaft 904. The chassis 905 is fixedly connected to the bottom of the temperature conducting tank 901. The top of the inner tank 903 is rotatably connected to the top of the temperature conducting tank 901. The cooling unit 9 also includes a worm gear 906 fixedly connected to the outside of the rotating shaft 904. A motor 907 is provided outside the worm gear 906. The bottom of the motor 907 is fixedly connected to the chassis 905. A worm 908 is fixedly connected to the drive end of the motor 907. The worm 908 meshes with the worm gear 906. During use, when the tank 1 is rapidly cooled, the gas pressure inside the tank 1 drops sharply, causing the vent plug 703 to move downwards. This downward movement of the vent plug 703 reduces the internal space, thus accommodating and alleviating the internal pressure of the tank 1. If the internal pressure continues to drop, it will further drive the vent plug 703 and the rod 704 downwards until the first toothed plate 801 abuts against the top of the cylinder 701. Simultaneously, the descent of the first toothed plate 801 will cause the first gear 804 to rotate, which in turn drives the first bevel gear. 806 rotates synchronously, and the first bevel gear 806 drives the second bevel gear 808 to rotate. The second bevel gear 808 synchronously drives the third gear 807 to rotate. The third gear 807 then drives the second toothed plate 809 to move. The movement of the second toothed plate 809 will drive the connecting rod 810 and the auxiliary plug 811 to move, thereby driving the auxiliary plug 811 to move outward from the connecting box 812, thus connecting the first auxiliary pipe 813 and the second auxiliary pipe 814. At this time, the tank 1 is connected to the outside, and internal and external pressure balance can be achieved.
[0022] Example 2
[0023] Please see Figures 1-8 The present invention provides a technical solution: Unlike Embodiment 1, this embodiment includes a tank body 1, with a cover 2 rotatably connected to the top of the tank body 1. Connecting plates 3 are fixedly connected to the outer sides of both the cover 2 and the tank body 1. A fixing screw 4 is threaded between the two connecting plates 3. Sealing rings 5 are fixedly connected to the bottom of the cover 2 and the top of the tank body 1. By setting the sealing rings 5, the sealing effect can be guaranteed. Furthermore, by rotating the fixing screw 4, the cover 2 and the tank 1 can be fixed in place; Adjustment unit 6 is disposed inside cover 2. Adjustment unit 6 includes main body 7, in which air vent plug 703 is disposed. Adjustment unit 6 also includes auxiliary body 8, in which auxiliary plug 811 is disposed.
[0024] The main body 7 includes a cylindrical body 701 fixedly connected inside the cover body 2. A slot 702 is provided inside the cylindrical body 701. The bottom of the cylindrical body 701 extends out of the cover body 2. A vent plug 703 is slidably connected inside the cylindrical body 701. A rod 704 is fixedly connected to the top of the vent plug 703. A fixing ring 705 is fixedly connected inside the cylindrical body 701. The top of the rod 704 passes through the fixing ring 705 and the top of the cylindrical body 701. A spring 706 is sleeved on the rod 704. like Figure 3As shown, it should be noted that the sliding process of the rod 704, the fixing ring 705, and the cylinder 701 is always in a sealed state. The sliding seal between the fixing ring 705 and the rod 704 uses the existing rubber seal technology, while the sliding seal between the top of the cylinder 701 and the rod 704 uses the existing lubricating oil seal technology. Through double sealing, leakage is avoided. Furthermore, by setting a spring 706, when the vent plug 703 descends, it will simultaneously drive the spring 706 to stretch. The spring 706 can provide elasticity, which makes it easy for the vent plug 703 to return to its original position, while also increasing the force to avoid damage caused by mistakes. At the same time, the top of the cylinder 701 can be removed, and springs 706 with different elasticities can be replaced. The main body 7 also includes a vent pipe 707 fixedly connected to the top of the cylinder 701. The vent pipe 707 is connected to the empty groove 702. Multiple vent holes 708 are opened on the inner wall of the cylinder 701. All multiple vent holes 708 are connected to the empty groove 702. When the tank 1 is rapidly cooled, the gas pressure inside the tank 1 drops sharply, which will cause the vent plug 703 to move downward. The downward movement of the vent plug 703 can reduce the internal space, thereby adapting to and relieving the internal pressure of the tank 1. The top of the spring 706 is fixedly connected to the retaining ring 705, and the bottom of the spring 706 is fixedly connected to the vent plug 703. The auxiliary component 8 includes a first toothed plate 801 fixedly connected to the top of the rod 704, a frame 802 provided outside the first toothed plate 801, a mounting bracket 803 fixedly connected to the top of the frame 802, the top of the mounting bracket 803 fixedly connected to the top of the inner part of the cover 2, a first gear 804 rotatably connected inside the frame 802, the first gear 804 meshing with the first toothed plate 801, a second gear 805 rotatably connected inside the frame 802, the second gear 805 meshing with the first gear 804, a first bevel gear 806 fixedly connected to one side of the second gear 805, a third gear 807 rotatably connected inside the frame 802, a second bevel gear 808 fixedly connected to one side of the third gear 807, the first bevel gear 806 and the second bevel gear 808 meshing, a second toothed plate 809 slidably connected to the bottom of the frame 802, a connecting rod 810 fixedly connected to one end of the second toothed plate 809, and an auxiliary plug 811 fixedly connected to one end of the connecting rod 810. The auxiliary component 8 also includes a connecting box 812 fixedly connected inside the cover 2. A first auxiliary tube 813 is fixedly connected to the top of the connecting box 812, and a second auxiliary tube 814 is fixedly connected to the bottom of the connecting box 812. Both the first auxiliary tube 813 and the second auxiliary tube 814 are connected to the connecting box 812. The first auxiliary tube 813 extends out of the cover 2, and the second auxiliary tube 814 extends into the tank 1. The auxiliary plug 811 is slidably and sealingly connected to the connecting box 812. like Figure 4 and Figure 5As shown, when the internal pressure continues to drop, it will drive the vent plug 703 and the rod 704 to move downward until the first toothed plate 801 abuts against the top of the cylinder 701. At the same time, the descent of the first toothed plate 801 will drive the first gear 804 to rotate, and then drive the auxiliary plug 811 to move outward from the connecting box 812, thereby connecting the first auxiliary pipe 813 and the second auxiliary pipe 814. At this time, the tank 1 is connected to the outside, and the internal and external pressure can be balanced. Furthermore, once the internal and external pressures are balanced, the vent plug 703 will rise back to its original position, simultaneously driving the rod 704 to rise. At the same time, the rod 704 will drive the auxiliary plug 811 to be pushed back into the connecting box 812, cutting off the internal and external channels. It should be noted that when the internal pressure increases suddenly, the vent plug 703 will continue to rise and leak out of the vent hole 708. At this time, the gas will enter the empty slot 702 through the vent hole 708 and then be output to the outside of the device through the vent pipe 707. The vent plug 703 will return to its original position and block the vent hole 708 after the internal and external pressures are balanced.

The bottom of the motor 907 is fixedly connected to the chassis 905. A worm 908 is fixedly connected to the drive end of the motor 907. The worm 908 meshes with the worm gear 906. It should be noted that the other end of the worm 908 is rotatably connected to the inner wall of the temperature conducting tank 901 to maintain stability. like Figure 8 As shown, when the motor 907 is started, the motor 907 drives the worm gear 908 to rotate, which in turn drives the worm wheel 906 to rotate. The worm wheel 906 then drives the rotating shaft 904 and the inner tank 903 to rotate as a whole. Internal rotation assists in cooling by enhancing the contact efficiency between the material and the cold source, disrupting the stabilizing layer that hinders heat transfer, and promoting uniform temperature distribution.
