Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of a reaction kettle, in particular to a stirring and air input device inside a reaction kettle. Background Art
[0002] When the laboratory conducts the manganese tetraoxide test, the manganese powder and air in the reactor need to react fully. When the air pipe is passed from the top of the reactor, the air can contact too few reactants when entering the reactor and cannot be fully oxidized. If the air pipe is placed at the bottom, the stirring rod and the air pipe will be entangled together, resulting in each test not being able to fully react within the specified time, and the manganese powder at the bottom cannot be stirred evenly. The manganese tetraoxide experiments have failed repeatedly. For this reason, technical improvements have been made to the existing technology, and a low-cost solution that can effectively meet the air injection needs in the reactor has been developed. Utility Model Content
[0003] The utility model aims to provide an air dispersing device for a reactor to solve the problems raised in the above background technology.

DETAILED DESCRIPTION
[0021] See also Figures 1 to 4 In the embodiment of the utility model, a reaction kettle air dispersing device comprises a kettle body 1, a feed pipe 2 is arranged at the bottom of the kettle body 1, and an integrated device is installed at the outlet of the feed pipe 2;
[0022] The integrated device includes a blind plate 4, a screw rod 5, a sealing end 10, a sealing ring 11 and a diffuser 13. The blind plate 4 is installed with the discharge pipe 2 by bolts. The center thread of the blind plate 4 is connected to the screw rod 5. The diffuser 13 is installed on the top of the screw rod 5 through the sealing end 10. A sealing ring 11 capable of sealing the diameter of the discharge pipe 2 is installed on the top periphery of the sealing end 10. An air passage 8 extending to the inside of the diffuser 13 is opened in the screw rod 5. The novel reactor air diffuser device is composed of a screw rod 5, a diffuser 13, a sealing ring 11, a blind plate 4, etc. By connecting the blind plate 4 with the flange of the reactor discharge pipe 2, the sealing ring 11 is sealed with the diameter of the reactor discharge pipe 2 by rotating the screw rod 5 to ensure that the reaction liquid cannot flow down. The air compressor delivers the air source into the air passage 8 through the main line 14. The air enters the diffuser 13 covered with small holes from the screw rod 5 under the action of pressure, and the diffuser 13 is diffused. The diffuser 13 disperses the air into fine airflows that enter the bottom of the reactor. The air emerges upward from the bottom, allowing the reactants in the reactor to fully contact with the air and be oxidized. At the same time, the fine airflow will also blow up the reactants settled at the bottom of the reactor and stir them together with the stirring rod again. This solves the problem of sufficient dissolution and reaction of the solids settled in the reactor and also allows the reactants in the reactor to be fully oxidized. After the reaction is completed, the screw 5 is twisted downward, and a gap is generated between the sealing ring 11 and the discharge port at the bottom of the reactor. The reaction liquid will flow out through the gap for discharge, thereby achieving the purpose of discharge. This technical improvement can maximize the savings in transformation costs, and there is no need to drill holes and cut the original reactor. The bottom precipitate is floated by dispersing the bottom air, and the original agitator is used for efficient stirring. At the same time, the amount of oxygen in the reactor is increased to meet the oxygen required for the reaction.
[0023] In a preferred embodiment, a closed loop 3 is provided inside the feed pipe 2. When the screw rod 5 moves upward, the diffuser 13 passes through the inner diameter of the closed loop 3, and the sealing ring 11 contacts and fits with the closed loop 3 for sealing. During the air injection reaction, the feed pipe 2 needs to be sealed to reduce the leakage of the reaction liquid from the gap. To this end, the closed loop 3 is added, and the sealing ring 11 contacts and squeezes the closed loop 3 to achieve a sealing effect. For the reaction of some substances, high pressure may be generated in the kettle, and the reaction liquid is more likely to leak out under high pressure.
[0024] In a preferred embodiment, a sealing ring 9 is provided at the bottom of the sealing end 10. When the screw rod 5 moves downward, the sealing ring 11 leaves the closed loop 3 to generate a feeding gap. The sealing ring 9 at the bottom of the sealing end 10 contacts and seals with the blind plate 4. After the reaction is completed, the screw rod 5 needs to be screwed downward to discharge the material. The connection between the screw rod 5 and the blind plate 4 is threaded, so liquid may seep into the thread gap. In order to improve the sealing of the threaded connection, the sealing ring 9 is driven to seal with the blind plate 4 by rotating the screw rod 5 downward to prevent leakage. A rotating handle 6 is provided at the bottom of the screw rod 5.
[0025] In a preferred embodiment, the blind plate 4 is equipped with a curved pipe 7, which is interconnected with the interior of the discharge pipe 2. A valve body is arranged at the end of the curved pipe 7. The diffuser 13 is hemispherical, hollow inside, and has evenly distributed air diffusion holes on the spherical surface. It also includes a discharge system, which includes a reflux line 15 and a delivery line 16. The curved pipe 7 is connected to the reflux line 15 and the delivery line 16 through a three-way valve. The reaction liquid seeping out under high pressure can be sent back to the reactor through the reflux line 15. The delivery equipment can select a liquid pump. After the reaction is completed, the reaction liquid can be sent out through the delivery line 16 by switching the three-way valve.
[0026] In a preferred embodiment, a neck tube 12 is further provided between the sealing end 10 and the diffuser 13. The air passage 8 inside the neck tube 12 is in a shape that gradually contracts upward, thereby increasing the air flow velocity so that the air can cover a larger range when discharged from the diffuser hole. A one-way valve can be provided on the main line 14 to prevent backflow.
[0027] It should be noted that the above embodiments all belong to the same utility model concept, and the description of each embodiment has its own focus. For matters that are not described in detail in some embodiments, reference can be made to the description in other embodiments.
[0028] The above-mentioned embodiments only express the implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
