[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Please refer to Figure 1-5 A pressure vessel with a pressure relief mechanism includes a pressure tank 1, a pressure gauge 2 fixedly connected to the top of the pressure tank 1, support frames 9 fixedly connected to both sides of the bottom of the pressure tank 1, a bottom plate 10 fixedly connected to the bottom end of the support frames 9, a discharge port 11 fixedly connected to the bottom end of one side of the pressure tank 1, and a pressure relief mechanism for automatic pressure relief provided at the top of the pressure tank 1.

[0027] The pressure relief mechanism includes a fixed cylinder 3. The fixed cylinder 3 is fixedly connected to one side of the top of the pressure tank 1. The bottom end of the fixed cylinder 3 is provided with a pressure relief port 14. The bottom end of the interior of the fixed cylinder 3 is provided with a movable baffle 5. The bottom end of the movable baffle 5 is fixedly connected with a sealing gasket 19. The top end of the interior of the fixed cylinder 3 is fixedly connected with a fixed plate 4. The bottom ends of the fixed plate 4 are fixedly connected with two sides of a limit sleeve 23. The top ends of the movable baffle 5 are fixedly connected with two sides of a limit post 24. The top ends of the movable baffle 5 are fixedly connected with two sides of a spring 20. The top end of the spring 20 is fixedly connected with an adjusting plate 25. The bottom ends of the adjusting plate 25 are provided with through holes 26 on both sides.

[0028] The limiting post 24 passes through the through hole 26 and extends into the interior of the limiting sleeve 23, and the limiting sleeve 23 is slidably connected to the limiting post 24;

[0029] The limiting post 24 is movably connected to the through hole 26, and the sealing gasket 19 is movably connected to the limiting sleeve 23;

[0030] Specifically, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, when the pressure inside the pressure tank 1 is too high during material storage, the movable baffle 5 inside the fixed cylinder 3 will be subjected to the pressure inside the pressure tank 1. When the pressure on the movable baffle 5 is too high, the pressure pushes the movable baffle 5 upward, causing it to rise. After the movable baffle 5 drives the sealing gasket 19 to disengage from the bottom of the fixed cylinder 3, the pressure inside the pressure tank 1 can enter the fixed cylinder 3 through the pressure relief port 14 and be discharged through the fixed cylinder 3 to achieve the pressure relief effect. After the pressure decreases, the spring 20 pushes the movable baffle 5 back to fit against the bottom of the fixed cylinder 3, thus realizing automatic pressure relief after the pressure is too high.

[0031] The top of the adjusting plate 25 is fixedly connected to a threaded cylinder 21, the top of the fixing plate 4 is fixedly connected to a fixing groove 17, the inside of the fixing groove 17 is movably connected to a rotating wheel 18, the bottom of the rotating wheel 18 is fixedly connected to a threaded rod 22, the threaded rod 22 passes through the fixing plate 4 and extends into the inside of the threaded cylinder 21.

[0032] The threaded cylinder 21 is threadedly connected to the threaded rod 22, and the center line of the threaded cylinder 21 and the center line of the adjusting plate 25 are on the same vertical plane.

[0033] Specifically, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, before storing materials, the rotating wheel 18 can be rotated to drive the threaded rod 22 to rotate. The threaded rod 22 pushes the adjusting plate 25 down through the threaded cylinder 21. When the adjusting plate 25 descends, it will squeeze the spring 20 to adjust its supporting force, thereby adjusting the pressure value that the movable baffle 5 can withstand. In addition, the limiting post 24 fits inside the through hole 26 to limit the adjusting plate 25, ensuring the stability of the adjusting plate 25 and keeping it in a horizontal state, thereby keeping the two sets of springs 20 under equal force, and realizing the ability to adjust the pressure relief threshold.

[0034] A feed inlet 12 is fixedly connected to one side of the pressure tank 1. A valve chamber 13 is fixedly connected to one side of the feed inlet 12. A cylinder 6 is fixedly connected to the top of the valve chamber 13. A connecting flange 7 is fixedly connected to one side of the valve chamber 13. An annular groove 15 is opened on one side of the connecting flange 7. A sealing ring 8 is fixedly connected to one side inside the annular groove 15. A fixing ring 16 is fixedly connected to the inside of the annular groove 15.

[0035] The fixed ring 16 is movably connected to the sealing ring 8, and the center line of the annular groove 15 is on the same vertical plane as the center line of the connecting flange 7.

[0036] The feed inlet 12 is connected to the interior of the pressure tank 1, and the valve chamber 13 is connected to the interior of the feed inlet 12;

[0037] Specifically, such as Figure 1 and Figure 2 As shown, before conveying materials, the external pipeline is attached to the connecting flange 7 and connected to it. After connection, the sealing ring 8 on one side of the connecting flange 7 is connected to the external pipeline to ensure sealing. The fixing ring 16 inside the annular groove 15 can support the sealing ring 8 and prevent the sealing ring 8 from deforming and affecting the sealing effect. After the connection is completed, the cylinder 6 is started to open the valve chamber 13, so that the material is introduced into the pressure tank 1 through the feed port 12, thus ensuring the sealing of the device.

[0038] Working Principle: In use, before storing materials, the rotating wheel 18 drives the threaded rod 22 to rotate. The threaded rod 22 pushes the adjusting plate 25 downwards through the threaded cylinder 21. When the adjusting plate 25 descends, it compresses the spring 20 to adjust its supporting force, thereby adjusting the pressure value that the movable baffle 5 can withstand. Furthermore, the limiting post 24, which fits inside the through hole 26, can limit the adjustment plate 25, ensuring its stability and keeping it horizontal. This maintains the even force on both sets of springs 20. When storing materials, if the pressure inside the pressure tank 1 is too high, the movable baffle 5 inside the fixed cylinder 3 will be subjected to the pressure inside the pressure tank 1. When the pressure on the movable baffle 5 is too high, the pressure pushes the movable baffle 5 upwards, causing it to rise. After the plate 5 drives the sealing gasket 19 to detach from the bottom of the fixed cylinder 3, the pressure inside the pressure tank 1 can enter the fixed cylinder 3 through the pressure relief port 14 and be discharged through the fixed cylinder 3 to achieve the pressure relief effect. After the pressure is reduced, the spring 20 pushes the movable baffle 5 back to fit against the bottom of the fixed cylinder 3. Before conveying materials, the external pipeline is attached to the connecting flange 7 and connected to it. After connection, the sealing ring 8 on one side of the connecting flange 7 is connected to the external pipeline to ensure sealing. The fixing ring 16 inside the annular groove 15 can support the sealing ring 8 to prevent the sealing ring 8 from deforming and affecting the sealing effect. After the connection is completed, the cylinder 6 is started to open the valve chamber 13, thereby introducing the material into the pressure tank 1 through the feed port 12.
