[0002] High gravity beds have wide applications in the chemical industry, such as distillation, absorption, desorption, and extraction. They can improve mass transfer efficiency, reduce equipment size and investment costs, and improve product quality and production efficiency. Gas sealing of high gravity beds is a technical means to prevent gas leakage. It is designed to ensure that gas is kept in the required position in a specific device, container, or system without leaking into the surrounding environment or mixing with other undesirable gases.

This gap poses a risk of gas leakage, affecting the normal operation and production efficiency of the equipment. Therefore, a gravity bed gas sealing device is needed, which uses continuous elastic compression to ensure that the seals and the equipment structure always maintain a tight fit, effectively preventing gas leakage caused by equipment vibration or seal wear.

[0021] In the following description, embodiments of the gravity bed gas sealing device of the present invention will be described with reference to the accompanying drawings.
[0022] Figure 1-4 This invention illustrates a gravity bed gas sealing device according to an embodiment of the present invention. It includes a lower flange 2 fitted onto the surface of a main rotating shaft 1. A dust cover 11 is connected to the top of the lower flange 2, covering the top of the surface of the main rotating shaft 1. A pressure plate 3 is bolted to the top of the lower flange 2. Two sleeves 4 fitted onto the surface of the main rotating shaft 1 are provided on the top of the pressure plate 3. A sealing ring 8 is provided between the lower flange 2 and the pressure plate 3, fitted onto the surface of the main rotating shaft 1. Both sides of the top of the pressure plate 3 are threaded with screws. Bolt 9, the bottom end of which penetrates to the bottom of pressure plate 3 and is threaded to the lower flange 2. A sliding sealing ring 10 is provided between the jackets 4, and the sliding sealing ring 10 is fitted onto the surface of the main shaft 1. Both ends of the two jackets 4 are fixedly connected by screws. Through the cooperation of the sliding sealing ring 10 and the sealing ring 8, a tight seal is achieved between the main shaft 1 and the lower flange 2, thereby preventing leakage at the connection point between the lower flange 2 and the main shaft 1. An elastic support assembly 5 is provided at the top of the jacket 4. The support assembly 5 includes a sliding sealing sleeve 51 fitted onto the surface of the main rotating shaft 1. An upper flange 6 is fixedly connected to the top of the surface of the main rotating shaft 1, and a fixed sealing sleeve 7 is fixedly connected to the inner cavity of the upper flange 6. The top of the sliding sealing sleeve 51 is in close contact with the bottom of the fixed sealing sleeve 7. Through the cooperative use of the fixed sealing sleeve 7 and the sliding sealing sleeve 51, a continuous elastic support force is provided between the main rotating shaft 1 and the upper flange 6, thereby ensuring that the fixed sealing sleeve 7 and the sliding sealing sleeve 51 always maintain a tight fit, thus improving the main rotating shaft's stability. The sealing effect between the rotating shaft 1 and the upper flange 6 is achieved by embedding a positioning ring 52 in the inner cavity of the sliding sealing sleeve 51, and two clamps 53 are fitted on the surface of the sliding sealing sleeve 51. Both ends of the two clamps 53 are fixedly connected by screws. Semi-circular positioning posts 54 are fixedly connected on both sides of the bottom of the clamps 53. Semi-circular positioning grooves 55 are opened on both sides of the top of the jacket 4. Springs 56 are installed in the inner cavity of the two semi-circular positioning grooves 55 on the same side. The top of the springs 56 is fitted on the surface of the two semi-circular positioning posts 54 on the same side.
[0023] Working principle: In use, the user uses the bolt 9 and pressure plate 3 to stably clamp and install the sealing ring 8 between the lower flange 2 and the pressure plate 3, sealing the main shaft 1 and the lower flange 2. Then, the user places the positioning ring 52 and the sliding sealing sleeve 51 on the surface of the main shaft 1, and clamps and fixes the sliding sealing sleeve 51 with the clamp 53. Next, the user places the sliding sealing ring 10 on the surface of the main shaft 1, and clamps and positions the sliding sealing ring 10 with the clamp 4. Finally, the user inserts the spring 56 halfway into the shaft. The inner cavity of the circular positioning groove 55 allows the spring 56 to be sleeved on the surface of the semi-circular positioning post 54. After assembly, the spring 56 generates a bidirectional elastic force, which elastically compresses the clamp 53 and the sleeve 4, allowing the sliding sealing sleeve 51 to be tightly attached to the bottom of the fixed sealing sleeve 7, thus compressing and sealing the connection between the fixed sealing sleeve 7 and the main rotating shaft 1. At the same time, the sleeve 4 drives the sliding sealing ring 10 to exert a continuous elastic compressive force on the sealing ring 8 downward, thereby performing a secondary seal on the connection between the sealing ring 8 and the main rotating shaft 1, effectively preventing gas leakage.
[0024] In summary, this gravity bed gas sealing device seals the top of the main shaft 1 surface through the cooperation of the upper flange 6 and the fixed sealing sleeve 7, seals the space between the lower flange 2 and the main shaft 1 through the cooperation of the pressure plate 3 and the sealing ring 8, and finally achieves an elastic seal between the upper flange 6 and the lower flange 2 through the cooperation of the jacket 4 and the elastic support assembly 5. This achieves continuous compression sealing and effectively prevents gas leakage.
