Therefore, this invention proposes a stirring structure for reactors to solve the above problems. Utility Model Content

The drive motor 3 drives the rotating shaft 4 to rotate, and the rotating shaft 4 can drive the stirring rod 18 to rotate. At this time, the stirring rod 18 can stir and mix the materials inside the reaction vessel, and at the same time, the rubber plate 21 can contact the inner wall of the reaction vessel to complete the scraping and cleaning of the inner wall.

[0019] The top of the cover 2 is equipped with a venting control seat 6, and multiple sets of venting control seats 6 are provided. The bottom of the cover 2 is fixedly connected to a mounting bracket 7, and the bottom of the mounting bracket 7 is fixedly connected to an upper sliding cover 8. The bottom of the upper sliding cover 8 is threadedly connected to a lower sliding cover 9, and the top of the lower sliding cover is equipped with a secondary gear 10. The driving gear 5 and the secondary gear 10 are rotated and meshed. The secondary gear 10 is installed on the top of the lower sliding cover, so that it can rotate on the top of the lower sliding cover. Through the threaded meshing connection between the lower sliding cover and the upper sliding cover 8, the secondary gear 10 can be restricted between the lower sliding cover and the upper sliding cover 8. At the same time, the secondary gear 10 and the driving gear 5 are meshed and rotate synchronously. The two form two sets of stirring structures with opposite rotation directions, which further improves the mixing degree of the materials inside the reactor, thereby improving the product production efficiency.

[0020] A gas outlet 11 is fixedly connected to the bottom of the auxiliary gear 10, and the gas outlet 11 is slidably engaged with the sliding cover. A gas outlet 14 is provided on the side of the gas outlet 11, and the gas outlet 14 adopts a one-way valve structure design. A stirring fan blade 15 is fixedly installed on the side of the gas outlet 11. The gas outlet 11 rotates under the drive of the auxiliary gear 10, and synchronously drives the stirring fan blade 15 to stir the material in the reaction vessel.

[0021] A static sealing seat 12 is installed on the top of the air outlet 11. The static sealing seat 12 is rotatably connected to the inner side of the air outlet 11. A connection socket 13 is fixedly installed on the top of the static sealing seat 12.

[0022] An air inlet pipe 16 is installed on the top of the ventilation control seat 6, and an air outlet pipe 17 is fixedly connected to the bottom of the ventilation control seat 6. The air outlet pipe 17 is plugged into the connection socket 13. During the process of mixing and stirring the material by driving the stirring fan blade 15 with the air outlet pipe 17, the reaction gas is introduced from the air inlet pipe 16, the ventilation control seat 6 and the air outlet pipe 17 by opening the ventilation control seat 6. The reaction gas will enter the internal sealed pipe of the air outlet pipe 17 from the connection socket 13 and be discharged into the material in the reactor from the one-way air outlet 14 set on the side of the air outlet pipe 17 to mix and react with it.

[0023] The bottom of the reactor body 1 is provided with a discharge port 19, and the side of the reactor body 1 is provided with a feed port 20.

[0024] In practical use: First, the auxiliary gear 10 needs to be installed on the top of the sliding cover 9, allowing it to rotate on the top of the sliding cover 9. The vent pipe 17 slides and inserts into the inner side of the brick at the bottom of the sliding cover 9. Then, through the threaded meshing connection between the sliding cover 9 and the upper sliding cover 8, the auxiliary gear 10 can be restricted between the sliding cover 9 and the upper sliding cover 8. At the same time, the auxiliary gear 10 meshes with the drive gear 5. Subsequently, the vent pipe 17 at the bottom of the vent control seat 6 is connected to the connection socket 13. After completing the installation of the stirring structure, materials are added to the reactor body 1, and then the sealing cover 2 is tightly connected to the reactor body 1. The drive motor 3 is started, and the drive motor 3 drives the rotating shaft 4 to rotate. The rotating shaft 4 can drive the stirring rod 18 to rotate. At this time, the stirring rod 18 can stir and mix the materials inside the reactor. The rubber plate 21 can contact the inner wall of the reactor to complete the scraping and cleaning of the inner wall. The auxiliary gear 10 rotates synchronously with the drive gear 5. The auxiliary gear 10 drives the gas outlet 11 and the stirring fan blade 15 to stir the material, forming two sets of stirring structures with opposite rotation directions, which further improves the mixing degree of the material inside the reactor, thereby improving the product production efficiency. Open the ventilation control seat 6 to introduce reaction gas from the inlet pipe 16, the ventilation control seat 6 and the outlet pipe 17. The reaction gas will enter the internal sealed pipe of the outlet pipe 17 from the connection socket 13 and be discharged into the material in the reactor from the one-way outlet 14 set on the side of the outlet pipe 17 to mix and react with it, which can effectively improve the reaction efficiency of the material and the gas, thereby improving the utilization efficiency of raw materials and reducing material waste. Finally, open the discharge port 19 to discharge the product.
