[0001] The utility model relates to the technical field of chemical equipment, in particular to an overpressure protection device for a lead-based reactor. Background Art

[0002] The pressure vessel main body is a sealed container main body that can withstand pressure. The pressure vessel main body has extremely wide uses and plays an important role and function in many departments such as industry, civil use, military, and many fields of scientific research.

[0003] A lead-based reactor is a reactor that can utilize a lead-based reactor as energy. During the operation of some lead-based reactors, users can confirm the pressure inside the reactor through the pressure gauge on the reactor. When the pressure inside the reactor is too high, the staff can operate to relieve the pressure of the reactor. However, if the staff fails to discover it in time, it is easy to cause safety accidents due to overpressure. To solve this technical problem, the utility model proposes an overpressure protection device for a lead-based reactor. Content of the Utility Model

[0007] Preferably, the transmission mechanism includes a motor, the motor is installed on the upper surface of the isolation layer, and the output end of the motor is connected to a threaded rod.

[0008] Preferably, the outer surface of the threaded rod is rotatably connected to the inside of the isolation layer, and a telescopic rod is threadedly connected to the outer surface of the threaded rod.

[0009] Preferably, the upper surface of the telescopic rod is connected to the bottom surface of the isolation layer, and the output end of the telescopic rod is connected to a transmission plate.

[0012] Preferably, a ventilation groove is provided inside the decompression cylinder, and a positioning plate is connected to the outer surface of the air outlet pipe, and the outer surface of the positioning plate is connected to the outer surface of the decompression cylinder.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, through the cooperation between the transmission plate and the upper electromagnet and other components, firstly, the transmission plate can move, and when the transmission plate moves, the upper electromagnet will move with it, so as to control the distance between the upper electromagnet and the lower electromagnet, the upper electromagnet can be energized to change the magnetic force, and the maximum pressure in the reactor is controlled by changing the magnetic force and position of the upper magnet. When the pressure in the reactor is too high, the control ball will be pushed up, and the gas in the reactor will be discharged through the air outlet pipe to reduce the pressure. After the pressure is low, the upper electromagnet will push the control ball downward again to seal the reactor again, which is very convenient and solves the problem that the staff did not find it and it is easy to cause safety accidents.

[0015] In the utility model, through the cooperation between the support plate and the positioning plate and other components, the support plate can limit the position to which the control ball can move, so that when the pressure of the control ball in the reactor is not enough to push the control ball, the control ball will not fall directly into the reactor body, thereby avoiding malfunction of the device. The positioning plate can provide support for the ventilation groove 13, so that the ventilation groove will not produce large shaking when discharging gas, thereby increasing the stability of the device, which is very easy to use.

Detailed implementation mode

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation modes.

[0023] As Figures 1-5 shown, a lead-based reactor overpressure protection device includes a reactor body 1. A reducing cylinder 2 is connected to the upper surface of the reactor body 1. A control ball 3 is slidably connected inside the reducing cylinder 2. The reactor body 1 fixes the position of the reducing cylinder 2. The gas inside the reactor body 1 can enter the reducing cylinder 2. The reducing cylinder 2 restricts the moving direction of the control ball 3. When the gas inside the reactor body 1 enters the reducing cylinder 2, it can push the control ball 3 to move upward.

[0024] An air outlet pipe 4 is connected to the inside of the reducing cylinder 2. A push plate 5 is slidably connected inside the reducing cylinder 2. The reducing cylinder 2 fixes the position of the air outlet pipe 4. When the position where the gas pushes the control ball 3 to move exceeds the interface of the air outlet pipe 4 inside the reducing cylinder 2, the gas can flow out from the air outlet pipe 4, and the air pressure inside the reactor body 1 will decrease. The reducing cylinder 2 controls the moving direction of the push plate 5.

[0025] A lower electromagnet 6 is installed on the upper surface of the push plate 5. An isolation layer 7 is connected to the inside of the reducing cylinder 2. An isolation cover 8 is connected to the upper surface of the isolation layer 7. The push plate 5 fixes the position of the lower electromagnet 6. The lower electromagnet 6 can generate a large magnetic force when energized. When the lower electromagnet 6 moves, it will drive the push plate 5 to move. The reducing cylinder 2 fixes the position of the isolation layer 7. The isolation layer 7 fixes the position of the isolation cover 8. The isolation layer 7 and the isolation cover 8 are used to prevent the magnetic force from affecting the items inside the isolation cover 8.

[0026] A transmission mechanism 9 is arranged inside the reducing cylinder 2. A transmission plate 10 is slidably connected inside the reducing cylinder 2. An upper electromagnet 11 is installed on the bottom surface of the transmission plate 10. The reducing cylinder 2 restricts the moving direction of the transmission plate 10 to avoid deviation in the moving position of the transmission plate 10. The transmission plate 10 fixes the position of the upper electromagnet 11. When the transmission plate 10 moves, it will drive the upper electromagnet 11 to move. The upper electromagnet 11 can generate a magnetic force when energized. There is a repulsive force between the upper electromagnet 11 and the lower electromagnet 6, and the repulsive force prevents the two magnets from approaching.

[0027] The transmission mechanism 9 includes a motor 901. The motor 901 is installed on the upper surface of the isolation layer 7. The output end of the motor 901 is connected to a threaded rod 902. The isolation layer 7 fixes the position of the motor 901 to prevent the motor 901 from self-rotating when starting. The motor 901 fixes the position of the threaded rod 902 and drives the threaded rod 902 to rotate by starting the motor 901.

[0028] The outer surface of the threaded rod 902 is rotationally connected to the inside of the isolation layer 7. The outer surface of the threaded rod 902 is threadedly connected to a telescopic rod 903. The isolation layer 7 limits the position where the threaded rod 902 can move, thereby reducing the vibration generated when the threaded rod 902 rotates. When the threaded rod 902 rotates, the output end of the telescopic rod 903 extends or retracts along with the rotation direction of the threaded rod 902. A stop block is provided inside the telescopic rod 903. This stop block can prevent the extension rod of the telescopic rod 903 from rotating along with the rotation of the threaded rod 902, and this stop block can only move within the groove opened inside the telescopic rod 903, thereby preventing the extension rod from extending outside the telescopic rod 903.

[0029] The upper surface of the telescopic rod 903 is connected to the bottom surface of the isolation layer 7. The output end of the telescopic rod 903 is connected to a transmission plate 10. The isolation layer 7 fixes the position of the telescopic rod 903 to prevent the telescopic rod 903 from rotating along with the rotation of the threaded rod 902. The telescopic rod 903 fixes the position of the transmission plate 10. When the telescopic rod 903 expands and contracts, it can drive the transmission plate 10 to move, thereby controlling the distance between the upper electromagnet 11 and the lower electromagnet 6. When their distance is close, the repulsive force is greater, and vice versa. The user can determine how much force is required for the control ball 3 to exceed the position of the pressure reducing cylinder 2 by adjusting the magnitude of the magnetic force and the distance between the upper electromagnet 11 and the lower electromagnet 6, so as to control the maximum pressure inside the reactor body 1.

[0030] A support plate 12 is connected inside the pressure reducing cylinder 2. The upper surface of the support plate 12 contacts the outer surface of the control ball 3. The pressure reducing cylinder 2 fixes the position of the support plate 12 to prevent the support plate 12 from moving, and provides support for the control ball 3 through the support plate 12 to prevent the control ball 3 from falling into the reactor body 1.

[0031] The bottom surface of the push plate 5 contacts the outer surface of the control ball 3. The outer surface of the lower electromagnet 6 is slidably connected to the inside of the pressure reducing cylinder 2. The outer surface of the upper electromagnet 11 is slidably connected to the inside of the pressure reducing cylinder 2. When the control ball 3 moves upward, it needs to push the push plate 5 to move, that is, it needs to push the lower electromagnet 6 to move. The pressure reducing cylinder 2 can limit the moving direction of the lower electromagnet 6 and the upper electromagnet 11 to avoid deviation in the moving position.

[0032] An air vent groove 13 is formed inside the pressure reducing cylinder 2. A positioning plate 14 is connected to the outer surface of the air outlet pipe 4, and the outer surface of the positioning plate 14 is connected to the outer surface of the pressure reducing cylinder 2. The air between the two electromagnets in the air vent groove 13 can flow, and the pressure reducing cylinder 2 will fix the position of the positioning plate 14, and the positioning plate 14 is used to provide support for the air outlet pipe 4.
