Description

Technical Field

[0001] The utility model relates to the field of 2-bromonaphthalene preparation, in particular to a stirring device used for 2-bromonaphthalene preparation. Background Art

[0002] Traditional stirring devices in the production of 2-bromonaphthalene have significant shortcomings. These include low stirring efficiency, high energy consumption, and uneven mixing. Traditional stirring devices typically utilize simple stirring blades, which often struggle to achieve ideal mixing when handling highly viscous materials. This low stirring efficiency consumes more energy and time during the production process, increasing production costs. Furthermore, uneven mixing can lead to unstable product quality, impacting the performance of the final product. Utility Model Content

[0003] The utility model is based on the above technical problems and proposes a stirring device for preparing 2-bromonaphthalene.

[0004] A stirring device for preparing 2-bromonaphthalene comprises: a stirring barrel, a top cover provided on the stirring barrel, a stirring motor provided in the middle of the top cover, an output shaft of the stirring motor connected to a stirring shaft, the stirring shaft passing through the top cover and extending into the stirring barrel, a spiral blade provided on the stirring shaft, and a multi-layer stirring device provided on the stirring shaft, each layer of the stirring device comprising a plurality of stirring blades uniformly distributed around the circumference, the stirring blades being connected and fixed to the stirring shaft via a cross bar, the stirring blades being twisted plates; a wall plate provided on the outer ring of the stirring blade, the wall plate being connected and fixed to the stirring shaft via upper and lower connecting rods, the outer side of the wall plate being in close contact with the inner wall of the stirring barrel.

[0005] Preferably, the stirring blades in each layer of the stirring device are staggered in distance.

[0006] Preferably, with the direction of rotation of the stirring shaft as the front, the wall plate is gradually tilted backward and upward, and the wall plate is twisted counterclockwise with its center as the fulcrum.

[0007] Preferably, a rotating bearing is fixedly provided at the center of the bottom of the mixing barrel, and the lower end of the mixing shaft is connected and fixed to the inner ring of the rotating bearing.

[0008] Beneficial effects:

[0009] 1. This device uses a multi-layer stirring device, each layer consists of multiple twisted plate stirring blades evenly distributed around the circumference. This design makes the stirring more complete, can effectively break the shear force in the liquid, and make the materials mixed more evenly. Compared with traditional stirring devices, the multi-layer layout ensures uniform mixing at different liquid depths, thereby improving the overall stirring effect;

[0010] 2. The distance between the stirring blades in each layer of the stirring device is staggered. This design further optimizes the stirring effect, avoids excessive concentration or sparseness of materials in local areas, and improves mixing uniformity;

[0011] 3. With the direction of rotation of the stirring shaft as the front, the wall plate is gradually tilted backward and upward, and the wall plate is twisted counterclockwise with its center as the fulcrum. This design makes the material not only subjected to radial force but also axial force during the stirring process, which cooperates with the spiral blades on the stirring shaft to further improve the circulation of the material and enhance the mixing effect.

[0016] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0017] like Figures 1 to 4 The stirring device shown is for preparing 2-bromonaphthalene, comprising a stirring barrel 1, provided with a top cover 2, a support leg 4 at the bottom of the stirring barrel 1, a discharge pipe 5 at one side of the center of the stirring barrel 1, a stirring motor 3 at the middle of the top cover 2, and a plurality of feeding pipes 6 on the top cover 2. The prepared raw materials are added to the stirring barrel 1 through the feeding pipes 6. The output shaft of the stirring motor 3 is axially connected to a stirring shaft 7, which extends through the top cover 2 into the stirring barrel 1. The stirring shaft 7 is provided with spiral blades 8. The stirring shaft 7 is also provided with a multi-layer stirring device, each layer of the stirring device comprising a plurality of stirring blades 9 evenly distributed around the circumference. The stirring blades 9 are fixedly connected to the stirring shaft 7 by a cross bar 10. The stirring blades 9 are twisted plates. The outer ring of the stirring blades 9 is provided with a wall plate 11. The wall plate 11 is fixedly connected to the stirring shaft 7 by two upper and lower connecting rods 12. The outer side of the wall plate 11 is closely attached to the inner wall of the stirring barrel 1.

[0018] As a further improvement, the stirring blades 9 in each layer of the stirring device are staggered in distance, which can stir the material more comprehensively. This design makes the stirring more sufficient, can effectively break the shear force in the liquid, and make the material mixing more uniform.

[0019] As a further improvement, with the direction of rotation of the stirring shaft 7 as the front, the wall plate 11 is gradually tilted backward and upward, and the wall plate 11 is twisted counterclockwise with its center as the fulcrum. The wall plate 11 rotates along the inner wall of the stirring barrel 1 as the stirring shaft 7, which will drive the nearby material to move upward and flow inward during the upward process. In order to ensure the coordination with the wall plate 11, when the spiral blade 8 is rotated, it will drive the material to flow downward to enhance the stirring and pushing effect of the material.

[0020] As a further improvement, a rotating bearing 13 is fixedly provided at the center of the bottom of the mixing barrel 1 , and the lower end of the mixing shaft 7 is connected and fixed to the inner ring of the rotating bearing 13 , thereby improving the rotation stability of the mixing shaft 7 .
