The outside of the tank body 4 is provided with a warning light 5, a buzzer 6 and an exhaust valve 7 from top to bottom. The warning light 5, the buzzer 6 and the exhaust valve 7 are all fixedly connected to the tank body 4.

[0024] The clamping component includes two symmetrically fixed electric push rods 11 on the top surface of the support platform 14. The ends of the electric push rods 11 are fixedly connected to arc-shaped clamping plates, which abut against the outside of the storage tank body 12. The bottom wall of the feeding end 1 has a guide groove 16, and a guide block 18 is slidably connected in the guide groove 16. A screw 17 is threaded through the guide block 18. One end of the screw 17 is rotatably connected to the inner wall of one side of the guide groove 16, and the other end is driven to a drive motor. The drive motor is fixed in the guide groove 16. The bottom wall of the feeding end 1 has a sliding groove 19, and a slider 20 is slidably connected in the sliding groove 19. The slider 20 is fixed to the bottom surface of the tank body 4.

[0025] The sealing element includes a support ring 25 fixed inside the connecting pipe 22. A sealing plate 23 is slidably connected below the support ring 25. A sealing groove 28 adapted to the sealing plate 23 is coaxially formed on the bottom surface of the support ring 25. Two guide rods 24 are symmetrically fixed on the top surface of the sealing plate 23. The two guide rods 24 slide through the sealing groove 28. A pressure ring 27 is fixed together on the top surface of the two guide rods 24. The end of the electromagnetic control valve 15 extends into the connecting pipe 22 and abuts against the pressure ring 27. A compressed spring 26 is sleeved on the outer edge of the guide rod 24. The spring 26 is located between the pressure ring 27 and the support ring 25. The top surface of the connecting pipe 22 abuts against the sealing ring 21. The sealing ring 21 is fixedly sleeved on the outer edge of the electromagnetic control valve 15.

[0026] Working principle: During use, the drive motor drives the screw 17 to rotate, and the screw 17 drives the guide block 18 to move within the guide groove 16. The guide block 18 drives the tank body 4 to move, causing the top of the tank body 4 to leak out from the feeding end 1. Then, the storage tank body 12 containing the gaseous raw material is placed on the support platform 14 inside the tank body 4. Then, the electric push rod 11 drives the arc-shaped clamp to fix the storage tank body 12. Then, the drive motor retracts the tank body 4 into the feeding end 1 through the screw 17. Then, the cylinder 13 drives the support platform 14 to move... The support platform 14 lifts the storage tank body 12, causing the end of the solenoid control valve 15 to extend into the connecting pipe 22. Simultaneously, the sealing ring 21 abuts against the top surface of the connecting pipe 22. When the solenoid control valve 15 extends into the connecting rod, it contacts the pressure ring 27 and presses the pressure ring 27 downwards. The pressure ring 27 drives the spring 26 to compress, and simultaneously, the pressure ring 27, through the guide rod 24, causes the sealing plate 23 to leave the sealing groove 28, thus opening the storage tank body 12. Then, the solenoid control valve 15 is opened, and the storage tank body 12, through the connecting rod... Connector 22 is connected to solenoid control valve 15. Spring 26 of the seal pushes pressure ring 27 to make sealing plate 23 tightly adhere to sealing groove 28 of support ring 25, ensuring airtightness at the connection. Pump body 2 draws material from storage tank through diversion pipe, which then enters heating box 3 or directly into distillation cylinder. At the same time, detector 9 monitors the gas concentration in tank 4 in real time. If connection pipe 22 or storage tank leaks, detector 9 detects that the gas concentration exceeds the standard and sends a signal to control system. Solenoid control valve 15 immediately closes, cutting off material delivery; at the same time, cylinder 13 activates. The plunger retracts, causing the support platform 14 to descend, which in turn moves the storage tank body 12 downward. Under the action of the spring 26, the sealing plate 23 further presses the sealing groove 28 to form a physical isolation. Then, the warning light 5 and the buzzer 6 are activated, the exhaust valve 7 is opened to release the leaked gas, and then the drive motor adjusts the horizontal position of the tank body 4 through the screw 17 to move the leaking tank body out of the work area. The electric push rod 11 releases the arc-shaped clamp, and the storage tank body 12 can be removed for maintenance. The nitrogen isolation chamber 10 and the tempered glass tank body 4 provide passive protection to prevent the leaked gas from coming into contact with the ignition source.
