[0024] 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.
[0025] Example 1:
[0026] Please refer to Figures 1-5, a reactor pressure control device, including a reactor body 1, a threaded block 3 is fixedly connected to both sides of the top of the reactor body 1, a sealing groove 2 is opened on the top of the reactor body 1, a sealing ring 4 is clamped inside the sealing groove 2, a top cover 5 is fixedly connected to the top of the sealing ring 4, a threaded block 2 8 is fixedly connected to both sides of the top cover 5, a fixing bolt 9 is connected to the inner thread of the threaded block 2 8, a pressure gauge 7 is provided on the right side of the top of the top cover 5, an air hole 6 is opened on the left side of the top of the top cover 5, a mounting cover 10 is fixedly connected to the top of the air hole 6, the diameter of the air hole 6 is smaller than the inner wall diameter of the mounting cover 10, and the air hole 6 is communicated with the inner wall of the mounting cover 10, and a pressure relief hole 11 is opened on the surface of the mounting cover 10. There are several pressure relief holes 11, and the pressure relief holes 11 are distributed in a ring array on the surface of the mounting cover 10, and the spacing between the pressure relief holes 11 is the same. A sealing block 17 is slidably connected to the inside of the mounting cover 10, and the top of the sealing block 17 is fixedly connected to the limit spring 16. The top of the mounting cover 10 is fixedly connected to the connecting tube 12, and the top of the connecting tube 12 is threadedly connected to the threaded rod 13, the top of the threaded rod 13 is fixedly connected to the handle 14, and the bottom of the threaded rod 13 is fixedly connected to the pressure block 15.
[0027] Working principle: When in use, the staff places the raw materials inside the kettle body 1 for processing. The pressure gauge can monitor the pressure inside the kettle body 1 in real time and display it on the dial. The staff can confirm the pressure inside the kettle body 1 through the pressure gauge. When the pressure inside the kettle body 1 is greater than the thrust of the limit spring 16, the gas on the inner wall of the kettle body 1 will push the sealing block 17 upward through the air hole 6. The upward movement of the sealing block 17 will squeeze the limit spring 16. When the sealing block 17 moves up to above the pressure relief hole 11, the air pressure inside the kettle body 1 will quickly release the pressure through the pressure relief hole 11. When the pressure is released, the pressure inside the kettle body 1 becomes smaller, and the limit spring 16 will push the sealing block 17 to re-seal the air hole 6, which is convenient for subsequent use. No manual operation is required by the staff, which improves work efficiency and is convenient for staff to use.
[0028] Compared with the related art, the reactor pressure control device provided by the present invention has the following beneficial effects: by setting a sealing block 17, an installation cover 10, etc. in conjunction with a limit spring 16, the limit spring 16 can push the sealing block 17 to seal the air hole 6. Only when the pressure inside the kettle body 1 is greater than the elastic force of the limit spring 16, the sealing block 17 will be pushed away from the air hole 6, thereby improving work efficiency and facilitating use by staff.
[0029] Example 2:
[0030] Please refer to Figures 1-6. A sealing groove 2 is provided on the top of the kettle body 1, and a sealing ring 4 is clamped inside the sealing groove 2. The top of the sealing ring 4 is fixedly connected to a top cover 5. An air hole 6 is provided on the left side of the top of the top cover 5. The top of the air hole 6 is fixedly connected to a mounting cover 10. A pressure relief hole 11 is provided on the surface of the mounting cover 10. A sealing block 17 is slidably connected to the inside of the mounting cover 10. The top of the sealing block 17 is fixedly connected to a limiting spring 16. The top of the mounting cover 10 is fixedly connected to a connecting tube 12. The top of the connecting tube 12 is threadedly connected to a threaded rod 13. The top of the threaded rod 13 is fixedly connected to a handle 14, and the bottom of the threaded rod 13 is fixedly connected to a pressing block 15.
[0031] Working principle: When the staff needs to adjust the pressure inside the kettle body 1, the staff can hold the handle 14 with their hand and rotate it. The rotation of the handle 14 will drive the threaded rod 13 to rotate, and the threaded rod 13 will push the pressure block 15 downward. The downward movement of the pressure block 15 will squeeze the limit spring 16 and cause the limit spring 16 to contract. The contraction of the limit spring 16 will increase its own elastic force, and cooperate with the sealing block 17 to increase the pressure demand inside the kettle body 1. By controlling the compression degree of the limit spring 16, the pressure relief inside the kettle body 1 can be accurately controlled, which is convenient for the staff to adjust.
[0032] Compared with the related art, the reactor pressure control device provided by the present invention has the following beneficial effects: by setting a pressure block 15, a connecting tube 12, etc. for use with a limit spring 16, the pressure block 15 can squeeze the limit spring 16 downward, and the limit spring 16 will enhance its own elastic force when compressed, and be used in conjunction with the sealing block 17, so that the pressure relief inside the reactor body 1 can be accurately controlled, which is convenient for the staff to use.
