[0001] The utility model belongs to the technical field of stirring kettles, and particularly relates to a layered stirring reactor. Background Art

[0002] A stirring kettle is a reaction vessel widely used in industries such as chemical engineering, food, and pharmaceuticals. In the actual production process, sometimes it is necessary to achieve multi-stage stirring to meet different process requirements.

[0003] After retrieval, a Chinese authorized patent in the related field, with the patent publication number: CN218890480U and the patent name: A multi-stage rate stirring kettle, has a specific structure including a kettle body, with a motor fixedly installed at its top end. The output end of the motor is connected to a first stirring rod, and the bottom end of the first stirring rod is connected to a multi-stage stirring mechanism. The multi-stage stirring mechanism includes a support plate, second stirring rods, a gear assembly, and an anti-settling component. Both ends of the support plate are fixedly connected to the inner wall of the kettle body. The first stirring rod is connected to the support plate and the gear assembly. One end of each of the two second stirring rods is connected to the gear assembly, and the anti-settling component is connected to the other end of the second stirring rod. The utility model uses the cooperation setting of the support plate, second stirring rods, and gear assembly. Through the gear assembly, the materials in the kettle body can form multiple vortices with different directions, radii, and rotation speeds under the stirring of multiple stirring rods. These vortices collide with each other, which can accelerate the material stirring process and improve the material stirring and mixing efficiency.

[0004] Regarding the above-mentioned multi-stage rate stirring kettle in the prior art, although it can drive the first stirring rod and the second stirring rod to work through the gear assembly to achieve the effect of separately stirring the upper and lower layers, considering that the gear assembly is located in the stirring chamber, after long-term use, the gear assembly may be corroded due to moisture or liquid erosion, affecting its service life and having a relatively high maintenance cost. Therefore, a layered stirring reactor is specifically provided to solve the above technical problems. Content of the Utility Model

[0005] In view of the multi-stage rate stirring kettle in the prior art, after long-term use, the gear assembly arranged inside it may be corroded due to moisture or liquid erosion, resulting in problems such as affecting the service life and high maintenance costs. The utility model provides a layered stirring reactor. By arranging a turbine inclined impeller on the lower part of the outer surface of the rotating rod and a blade mechanism on the upper part of the outer surface of the rotating rod, when the rotating rod rotates, it can drive the turbine inclined impeller and the blade mechanism to rotate synchronously. The turbine inclined impeller can generate strong eddy currents and shear forces in the lower part of the inner cavity of the tank body, enabling the materials to be fully stirred and mixed at the bottom, effectively preventing the occurrence of precipitation and accumulation phenomena. And the blade mechanism can fully stir the upper-layer materials and effectively exchange and blend them with the lower-layer materials. This way of upper and lower layered stirring is more convenient to use and has lower maintenance costs, solving the problems of the multi-stage rate stirring kettle in the prior art that after long-term use, the gear assembly arranged inside it may be corroded due to moisture or liquid erosion, affecting the service life and having high maintenance costs. The specific technical solution is as follows:

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3 , the present utility model provides a technical solution:

[0021] A layered stirring reactor, comprising a tank body 1 with feet at the bottom, characterized in that a stirring motor 2 is fixedly installed on the upper surface of the tank body 1, a rotating rod 21 is rotatably installed in the tank body 1, the top end of the rotating rod 21 is fixedly connected to the output end of the stirring motor 2, and a turbine inclined paddle 3 is fixedly installed on the lower part of the outer surface of the rotating rod 21. An adjustable inclination angle blade mechanism 4 is installed on the upper part of the outer surface of the rotating rod 21. Feeding hoppers 13 are fixedly installed on both the left and right sides of the tank body 1, and a drain pipe 14 with a valve is fixedly installed on the lower surface of the tank body 1.

[0022] During use, as Figure 2 shown, the materials to be stirred and mixed are respectively put into the tank body 1 from the feeding hoppers 13 on both sides. After feeding, connect the stirring motor 2 to the power supply and start it. The stirring motor 2 drives the turbine inclined paddle 3 and the blade mechanism 4 through the rotating rod 21 to stir the upper and lower layers of the materials respectively. Since the turbine inclined paddle 3 is inclined, it can generate a strong eddy current and shear force at the bottom, prevent the materials from precipitating and accumulating, and ensure that the materials with a large density or easy to settle are evenly dispersed. The blade mechanism 4 pushes the upper layer of materials in the water for stirring, which can generate a vertical flow, so that the upper layer of materials is fully stirred and effectively exchanged and integrated with the lower layer of materials, thereby enhancing the stirring effect. Compared with the prior art, this stirring reactor can stir the materials through different cutting angles for the upper and lower layers respectively. On the premise of not affecting the stirring effect, the structure is simpler, the maintenance cost is lower, and it is more convenient for practical application.

[0023] It should be noted that, in combination with Figure 3 and Figure 2 shown, the blade mechanism 4 includes a sleeve block A41 and a sleeve block B42. The sleeve block A41 is slidably connected to the rotating rod 21, and a tightening bolt 411 is screwed between the sleeve block A41 and the rotating rod 21. The sleeve block B42 is sleeved on the rotating rod 21, and a long bolt 421 is fixedly installed between the sleeve block B42 and the rotating rod 21. Connecting plates 44 are rotatably installed on both the left and right sides of the sleeve block A41, and sliding sleeves 441 are fixedly installed at the ends of the connecting plates 44 away from the sleeve block A41. Blades 43 are rotatably installed on both the left and right sides of the sleeve block B42, and sliding grooves 431 are formed through the front surfaces of the blades 43. The sliding grooves 431 are slidably connected to the corresponding sliding sleeves 441;

[0024] During the actual use process, the angle between the blade 43 and the rotating rod 21 can be adjusted according to the use requirements. When adjusting, only loosen the tightening bolt 411, slide the position of the sleeve block A41 up and down, and drive the corresponding blade 43 to flip and adjust through the connecting plate 44 and the sliding sleeve 441. After adjusting to the appropriate angle, tighten the tightening bolt 411 to fix the position of the sleeve block A41.

[0025] In addition, when adjusting the angle of the blade 43, for the convenience of operation, as Figure 1As shown in the figure, a window 11 is provided on the upper surface of the tank body 1, and a window cover plate 12 for covering the window 11 is rotatably installed on the upper surface of the tank body 1. The sleeve block A411 can be operated through the position of the window 11 to complete the adjustment of the blade 43.

[0026] Finally, to prevent the material from adhering to the bottom of the tank body 1 and affecting the stirring effect, as Figure 2 shown, L-shaped scrapers 5 are fixedly installed on both the left and right sides of the bottom of the rotating rod 21. The lower surface of the L-shaped scraper 5 is in contact with the lower surface of the inner cavity of the tank body 1, and the outer side of the L-shaped scraper 5 is in contact with the inner side wall of the tank body 1. When the rotating rod 21 rotates, the L-shaped scraper 5 can be driven to rotate in real time, so as to scrape the material on the bottom of the tank body 1 and ensure the stirring effect.
