Description

Technical Field

[0001] This utility model relates to the technology of reaction vessel stirring equipment, specifically a stirring device for carbonyl synthesis reaction vessels. Background Technology

[0002] Butanol and octanol can be produced in the same unit using a hydroxyl synthesis method, hence the common name butanol and octanol. Butanol and octanol are important raw materials for the synthesis of fine chemical products, mainly used in the production of plasticizers, solvents, dehydrating agents, defoamers, dispersants, flotation agents, petroleum additives, and synthetic fragrances. Large-scale butanol and octanol synthesis reactors with stirring devices are used for the large-scale synthesis reaction of butanol and octanol.

[0003] Existing carbonyl synthesis reactor stirring devices require careful attention to their sealing structure to prevent leakage of raw materials or products. However, because the stirring device is located at the top of the reactor, it is difficult to seal it completely. Any leaked raw material gases will escape immediately, resulting in poor detection effectiveness for the detection structure placed close to the top seal. Therefore, we propose a carbonyl synthesis reactor stirring device to solve the aforementioned problems. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Please see Figures 1-5 As shown, the carbonyl synthesis reactor stirring device includes a reactor 1, a protective frame 2 is provided on the reactor 1, and a stirring mechanism 3 is provided inside the protective frame 2. The protective frame 2 is used to support and protect the stirring mechanism 3 to prevent operators from accidentally touching the stirring rod and causing injury.

[0022] The detection sealing assembly includes a detection sensor 4 mounted on the protective frame 2, and an isolation plate 5 fixedly connected to the inner side of the protective frame 2. A support rod 6 is fixedly connected to the bottom of the isolation plate 5, and a balance plate 7 is mounted outside the support rod 6. A rotating shaft 8 is rotatably connected inside the support rod 6, and the balance plate 7 is rotatably connected to the outside of the rotating shaft 8. A spring 9 is provided between the balance plate 7 and the isolation plate 5. A sealing block 10 is fixedly connected to one end of the balance plate 7. A groove 11 is provided on the isolation plate 5, and a gas collection hood 12 is fixedly connected to the end of the balance plate 7 near the spring 9. A connecting seat 13 is provided on the inner side of the protective frame 2 away from the detection sensor 4, and a cooling fan 14 is provided inside the connecting seat 13. A guide pipe 15 is fixedly connected to the connecting seat 13.

[0023] It should be noted that the detection sensor 4 uses any detector capable of detecting the concentration of the reactants, and is combined with a common temperature sensor to form the main body of the detection sensor 4. The isolation plate 5 is used to separate the upper and lower layers inside the protective frame 2; the lower layer is sealed, and the upper layer is open to facilitate heat dissipation. The support rod 6 is used to fix the balance plate 7 and forms a lever structure with the rotating shaft 8 mounted on it and the balance plate 7. The spring 9 is used to ensure that the side of the balance plate 7 closest to the cooling fan 14 is always lowered. The balance plate 7 should be made of low-density hard material to reduce the amount of power required to drive its rotation. The sealing block 10 is used to seal the tank 11 and, when necessary, moves with the balance plate. 7. Rotate to open the tank 11 for ventilation. The gas collection hood 12 is used to guide the airflow direction and reduce the outlet radius to increase the thrust on the gas collection hood 12. The cooling fan 14 is controlled by the controller. Through the set detection sealing component, the connection between the top of the reactor 1 and the stirring structure can be sealed. The detection sensor 4 is set in the protective frame 2 to detect the concentration of leaked raw materials in the closed space, which improves the detection effect and the timeliness of leakage detection. At the same time, the airflow blown by the cooling fan 14 can drive the tank 11 to open for heat dissipation, avoid the transmission shaft from lubrication failure or metal fatigue due to long-term friction and heat generation, and prevent overheating shutdown.

[0024] An air inlet is provided on one side of the connecting seat 13. A rotating plate 16 is rotatably connected inside the air inlet. The rotating plate 16 can be driven when the cooling fan 14 is started. By creating a negative pressure in the air inlet, the rotating plate 16 is opened, which facilitates the entry of external airflow into the sealed space. When the cooling fan 14 stops, it closes under the action of gravity. In order to improve its sealing effect, a reset torsion spring can be appropriately set on its rotating shaft to ensure the sealing effect after reset.

[0025] The balance plate 7 has a strip groove 17, through which the support rod 6 passes. The strip groove 17 facilitates the passage of the support rod 6 and avoids interference.

[0026] The top of the groove 11 is a square groove, and the bottom of the groove 11 is an arc-shaped groove that adapts to the outer contour of the sealing block 10. The groove 11 can adapt to the shape of the sealing block 10 so that the sealing block 10 can rotate normally with the balance plate 7 and will not interfere with the isolation plate 5.

[0027] The isolation plate 5 has a circular hole, and a dynamic sealing ring is installed in the circular hole. The dynamic sealing ring is used to seal the gap between the rotating drive shaft and the isolation plate 5 to prevent gas from flowing out.

[0028] In specific implementation of this utility model: First, connect the device to a power source. During the carbonyl synthesis reaction, the gas sensor on the detection sensor 4 detects the raw material concentration in the sealed cavity of the protective frame 2 to determine whether there is a leak at the connection between the reactor and the stirring mechanism 3. At the same time, the temperature sensor in the detection sensor 4 can detect the temperature in the sealed cavity. When the temperature is higher than the set value, the detection sensor 4 sends a signal to the controller, which controls the cooling fan 14 to work. When the cooling fan 14 rotates, it creates a negative pressure behind it, causing the rotating plate 16 to be attracted and rotated to open the rear air inlet. Then, the airflow enters the guide pipe 15 through the cooling fan 14, and is ejected through the guide pipe 15 to contact and push the gas collection hood 12, thereby driving the balance plate 7 to rotate around the rotating shaft 8. At the same time, the spring 9 is compressed, causing the sealing block 10 to rotate. Simultaneously, the tank 11 is opened, allowing the high-temperature gas in the sealed cavity to be discharged upward through the tank 11. After a certain period of time, the controller controls the cooling fan 14 to turn off.
