[0002] Reactors are commonly used equipment in the chemical industry. Their principle is to stir various media in the reactor body through a paddle stirrer to make the materials evenly dispersed and react. There are many types of reactors. The basic principle of magnetic stirring reactors is to use the principle of like charges repel and opposite charges attract in the magnetic field. The magnetic field is used to drive the magnetic stirrer placed in the container to rotate in a circle, thereby achieving the purpose of stirring.

[0003] However, the stirring units in the existing glass reactor bodies are welded and have a relatively fixed structure. After stirring, it is very inconvenient to clean the inside of the glass reactor. Since sticky compounds may adhere to the inner wall, a brush is needed to rub and clean the inner wall. However, the multiple stirring rods inside block the cleaning, making it inconvenient to clean with a brush. In addition, it takes up more space during the early mass production, transportation and carrying processes. In the event of damage in the later stage, the entire stirring unit can only be replaced, and the maintenance cost is relatively high. Summary of the invention

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Please refer to Figure 1-Figure 3 The utility model provides a technical solution: a magnetic stirring glass reactor, comprising: a reactor body 10, a reactor cover 11 is arranged on the reactor body 10, a stirring shaft 12 extending to the inside of the reactor body 10 is connected to the bottom of the reactor cover 11, a plurality of longitudinally arranged stirring components 20 are arranged on the stirring shaft 12, an inner magnetic rotor 13 is connected to the bottom of the stirring shaft 12, an outer magnetic rotor 14 is arranged at the outer bottom of the reactor body 10, a driving mechanism 30 is arranged at the bottom of the outer magnetic rotor 14, and the driving mechanism 30 includes a motor 31, and the rotation of the motor 31 drives the rotation of the outer magnetic rotor 14 and the rotation of the stirring components 20 on the inner magnetic rotor 13 drives the internal mixed liquid to be fully mixed.

[0026] In some embodiments of the utility model, a feed port 112 is provided on the reactor cover 11, a discharge port 113 is provided at the bottom of the reactor body 10, and a valve 114 is provided on the discharge port 113. The reaction liquid flows into the reactor body 10 through the feed port 112, and after the experiment, the valve 114 is opened to allow the reacted liquid to flow out from the discharge port 113.

[0027] In some embodiments of the present invention, the external magnetic rotor 14 is coated on the bottom of the reactor body 10, and a gap is provided between the external magnetic rotor 14 and the outer peripheral wall of the reactor to prevent the external magnetic rotor from rubbing against the peripheral wall of the reactor body 10 during rotation, thereby affecting the rotation speed.

[0028] In some embodiments of the utility model, the driving mechanism 30 also includes two electric telescopic rods 32, the output ends of the electric telescopic rods 32 are fixedly connected to the bottom of the external magnetic rotor 14, the bottom of the electric telescopic rods 32 is connected to a rotating plate 34, and the bottom of the rotating plate 34 is connected to the output shaft of the motor 31.

[0029] The rotation of the motor 31 drives the rotation of the rotating plate 34 and the electric telescopic rod 32, so that the electric telescopic rod 32 drives the rotation of the outer magnetic rotor 14, and the electric telescopic rod 32 can more conveniently adjust the distance between the outer magnetic rotor 14 and the inner magnetic rotor 13. According to the principle of like charges repel each other and opposite charges attract each other, the outer magnetic rotor 14 drives the inner magnetic rotor 13 to rotate, and the inner magnetic rotor 13 fits the bottom of the reactor body 10, so as to facilitate the stirring of the solids settled at the bottom, thereby greatly improving the efficiency of mixing and stirring.

[0030] In some embodiments of the utility model, the stirring component 20 includes a fixed block 21, which is connected to a first connecting rod 22 via a rotating shaft 28, and the first connecting rod 22 is provided with a slide groove 23 extending along its length direction, and a spring 24 is provided in the slide groove 23, one end of the spring 24 is connected to one end of the inner wall of the slide groove 23, and the other end of the spring 24 is connected to a slider 25, and the other end of the slider 25 is connected to a second connecting rod 26, and the other end of the second connecting rod 26 is connected to a stirring paddle 27 via bolts.

[0031] When the motor 31 rotates, the first connecting rod 22 is driven to rotate along the rotating shaft 28 by inertia, so that the first connecting rod 22 and the fixed block 21 are kept horizontal or at a certain angle. At the same time, the second connecting rod 26 is slid out of the slide groove 23 by inertia, and the slider 25 is used to limit the second connecting rod 26. The second connecting rod 26 is used to push the distance between the stirring paddle 27 and the stirring shaft 12. The first connecting rod 22 and the second connecting rod 26 are used to stir the mixed liquid in the horizontal direction, and the stirring paddle 27 is used to stir the mixed liquid in the longitudinal direction, so that the mixed liquid is stirred in different dimensions, so that the stirring is more uniform, the data is more accurate, and the experimental data is more convincing. On the contrary, when the motor 31 stops rotating, the reset action of the spring 24 is utilized to pull the slider 25 and the second connecting rod 26 back, and the gravity of the first connecting rod 22 is rotated downward, so that the first connecting rod 22 forms a 90° angle with the fixed block 21, thereby folding and storing the first connecting rod 22 and the second connecting rod 26, so as to facilitate the sterilization and cleaning of the interior of the kettle after the experiment, avoid the obstruction of the internal stirring rod, which is not conducive to cleaning, and is convenient for early production, transportation and carrying, and also convenient for the later replacement of a single part, thereby reducing unnecessary waste.

[0033] The cooperation of the support frame 15 and the support ring 16 makes the reactor body 10 more stable when rotating, thus avoiding shaking, which would affect data detection and cause inaccurate data.

[0034] In some embodiments of the utility model, a support plate 18 is provided under the support frame 15, and the motor 31 is located on the support plate 18. The motor 31 is fixedly supported by the support plate 18, and the adhesion of pollutants on the ground is avoided, which requires frequent cleaning.
