Description

Technical Field

[0001] This utility model relates to a sodium metabisulfite reaction vessel, belonging to the technical field of sodium metabisulfite reaction vessel. Background Technology

[0002] Sodium metabisulfite is an inorganic compound, a white or yellow crystal with a strong, pungent odor. It is soluble in water, and its aqueous solution is acidic. When it comes into contact with strong acids, it releases sulfur dioxide and forms corresponding salts. Currently, the reaction vessel for preparing sodium metabisulfite uses a stirring mechanism to mix the solution with the gas.

[0003] Chinese Patent No. CN220780357U discloses a sodium metabisulfite preparation reactor. This invention includes a base frame, with a fixed bracket fixedly connected to the top of the base frame. Four fixed brackets are fixedly connected to the bottom of the base frame at the four upper corners. The fixed brackets are square rods. A placement rack is fixedly connected to the center of the base frame. Support rings are fixedly connected to the inner side walls of the fixed brackets. A reactor is located between the four support rings. The top edge of the reactor is located at the top of the support rings. The top of the reactor has a sealing cap. Bolts are inserted into the edge of the sealing cap, penetrating the top edge of the reactor and the support rings. Nuts are threaded onto the bottom of the outer wall of the bolts, located at the bottom of the support rings. The top edge of the reactor and the bottom edge of the sealing cap both protrude outwards. Sealing grooves are formed on the upper part of the top edge of the reactor and the lower part of the bottom edge of the sealing cap.

[0004] The aforementioned patent has some shortcomings: by pouring the reaction solution into the reaction vessel and using an inlet pipe to pass the reaction gas to the bottom of the solution and allow it to fully react with the solution during its ascent, the gas only contacts the liquid around the inlet pipe during its ascent, and cannot make uniform and sufficient contact with all the liquid in the reaction vessel. Therefore, it needs to be improved. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a sodium metabisulfite reaction vessel, including a reaction tank 1, a partition 2 installed inside the reaction tank 1, and a rotary gas-feeding component provided on the partition 2, a stirring component and a driving component also provided on the partition 2, a liquid inlet pipe 15 installed near the top of the outer wall of the reaction tank 1, a drain pipe 16 installed at the bottom of the outer wall of the reaction tank 1, and an exhaust pipe 14 installed on the reaction tank 1, and the exhaust pipe 14 is provided with a device for treating the discharged gas; The rotary aeration assembly includes a rotary pipe 3, a cyclone connector 4, a stirring pipe 6, and an exhaust port 7. The rotary pipe 3 is vertically rotatably installed through the top of the partition 2, and multiple stirring pipes 6 are installed on the outside of the rotary pipe 3. Multiple exhaust ports 7 are installed on each stirring pipe 6, and the cyclone connector 4 is installed on the top of the rotary pipe 3. Specifically, the outer wall of the reaction vessel 1 is provided with a liquid inlet pipe 15 near the top for adding reaction liquids such as sodium sulfite solution, and a drain pipe 16 at the bottom for discharging the sodium metabisulfite solution after the reaction is completed. The top is provided with an exhaust pipe 14, on which a gas treatment device, such as an alkaline absorption tower, is installed. This is existing technology and is used to purify the excess sulfur dioxide gas generated in the reaction to avoid environmental pollution. When the rotary gas-feeding assembly is in operation, the gas inlet pipe 5 delivers the gas required for the reaction, such as sulfur dioxide, to the cyclone connector 4. The cyclone connector 4 ensures a stable flow of gas into the rotating pipe 3 during its rotation. The gas then flows through the rotating pipe 3 to various stirring pipes 6, and finally is evenly discharged from multiple exhaust ports 7 on the stirring pipes 6 into the reaction liquid inside the reaction tank 1. Simultaneously, the rotation of the rotating pipe 3 drives the stirring pipes 6 to rotate as well, causing the exhaust ports 7 to continuously change position within the reaction liquid, allowing the gas to contact a wider area of ​​the reaction liquid, greatly increasing the gas-liquid contact area and reaction efficiency. Furthermore, the stirring assembly includes a stirring rod 8, stirring blades 9 and a third gear 13. The stirring rod 8 is vertically rotatably installed through the top of the partition 2, and multiple stirring blades 9 are installed on the outside of the stirring rod 8. The third gear 13 is installed on the top of the stirring rod 8. Specifically, during operation, the rotation of the stirring rod 8 causes the stirring blade 9 to rotate in the reaction liquid. The stirring blade 9 stirs the reaction liquid, breaking its static state and creating convection currents. This allows the reaction liquid in different areas to mix, preventing localized reactions from becoming too concentrated or insufficient. Furthermore, the stirring blade 9 and the stirring tube 6 are interlocked and do not interfere with each other during operation, further enhancing the stirring effect on the reaction liquid and making the reaction more uniform.

[0020] Furthermore, the drive assembly includes a motor 10 and a first gear 11. The motor 10 is mounted on the top of the partition 2, and the first gear 11 is mounted on the output end of the motor 10. A second gear 12 meshes with the outer side of the first gear 11, and the second gear 12 is sleeved and mounted on the rotating tube 3. Specifically, when the drive component is working, the motor 10 starts and drives the first gear 11 at the output end to rotate. Since the first gear 11 and the second gear 12 mesh with each other, the rotation of the first gear 11 will drive the second gear 12 to rotate. The second gear 12 is sleeved on the rotating tube 3, thereby driving the rotating tube 3 to rotate and providing power to the rotating gas filling component.

[0021] Furthermore, an inlet pipe 5 is installed through the top of the reaction vessel 1, and the bottom of the inlet pipe 5 is installed at the top of the cyclone connector 4; Specifically, the connection between the gas inlet pipe 5 and the cyclone connector 4 enables the continuous introduction of gas into the rotating pipe 3, ensuring the continuity of gas supply to the rotating gas supply component and allowing gas to continuously enter the reaction liquid to participate in the reaction.

[0022] Furthermore, the second gear 12 is meshed with the third gear 13 on both outer sides; Specifically, the second gear 12 has a third gear 13 meshing on both sides. When the second gear 12 rotates under the drive of the first gear 11, it will simultaneously drive the third gear 13 on both sides to rotate, thereby driving the stirring rod 8 connected to the third gear 13 to rotate. In this way, the rotating aeration component and the stirring component are driven by one motor 10 at the same time, saving power source, reducing equipment cost, and ensuring the coordination of the movement of the two components.

[0023] Furthermore, the stirring blade 9 and the stirring tube 6 are interlocked; Specifically, the interlocking arrangement of the stirring blade 9 and the stirring tube 6 means that the stirring blade 9 can move in the gap between the stirring tubes 6. This structural design allows the stirring blade 9 and the stirring tube 6 to cover the reaction space inside the reaction vessel 1 to the maximum extent when they rotate, so as to carry out all-round stirring and aeration of the reaction liquid, further improving the gas-liquid mixing effect and promoting the full progress of the reaction.

[0024] The workflow of this embodiment is as follows: First, an appropriate amount of reaction liquid is added to the reaction tank 1 through the liquid inlet pipe 15. Then, the gas required for the reaction is introduced through the gas inlet pipe 5. The gas enters the rotating pipe 3 through the cyclone connector 4, and then is discharged into the reaction liquid through the exhaust port 7 on the stirring pipe 6. Next, the motor 10 is started, which drives the first gear 11 to rotate. The first gear 11 drives the second gear 12 to rotate, thereby causing the rotating pipe 3 and the stirring pipe 6 to rotate. At the same time, the second gear 12 drives the third gears 13 on both sides to rotate, thereby causing the stirring rod 8 and the stirring blade 9 to rotate. Under the combined action of the rotating and exhausting of the stirring pipe 6 and the rotating and stirring of the stirring blade 9, the gas and the reaction liquid are fully mixed and react. The excess gas generated during the reaction is discharged through the exhaust pipe 14 and treated in the treatment device on the exhaust pipe 14 to avoid environmental pollution. After the reaction is completed, the reaction products are discharged through the drain pipe 16.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
