During the production and processing of Bordeaux 4BL pigment, multiple processing steps are required, and a reaction kettle is used to mix the raw materials.

[0003] Currently, when using a reaction kettle to mix the raw materials of Bordeaux 4BL pigment, most directly put all the raw materials into the interior of the reaction kettle at one time and then mix all the raw materials. This method has a poor mixing effect on the raw materials and is prone to uneven mixing, which is not conducive to the production of Bordeaux 4BL pigment. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the following disadvantages in the prior art: Currently, when using a reaction kettle to mix the raw materials of Bordeaux 4BL pigment, most directly put all the raw materials into the interior of the reaction kettle at one time and then mix all the raw materials. This method has a poor mixing effect on the raw materials and is prone to uneven mixing, which is not conducive to the production of Bordeaux 4BL pigment. A mixing reactor for producing Bordeaux 4BL pigment is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

Detailed implementation manners

[0020] 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 of the embodiments.

[0021] Terms such as "upper", "lower", "left", "right", "middle", and "one" cited in the present utility model are only for the sake of clarity in narration, rather than to limit the scope of implementation of the present utility model. The change or adjustment of their relative relationship, without substantial change in technical content, should also be regarded as the scope of implementation of the present utility model.

[0022] Referring to Figures 1-4 , a mixing reactor for the production of Baohong 4BL pigment, comprising a kettle body 1, two feed pipes 2 fixedly connected to the kettle body 1, a rotating shaft 6 rotatably installed on the kettle body 1, a rotating block 5 and a plurality of inclined stirring rods 7 fixedly connected to the rotating shaft 6. The upper inner wall of the kettle body 1 is connected to a hollow cylinder 14 through a torsion spring 13. The hollow cylinder 14 is connected to two sealing covers 12 through two bent rods 11. An installation cavity is formed in the rotating block 5, and a sliding assembly is arranged in the installation cavity. The sliding assembly includes a pressing block 9 slidably installed inside the installation cavity. A fixing plate 19 is fixedly installed inside the installation cavity. The fixing plate 19 is connected to a sliding rod 18 through a first spring 20. The sliding rod 18 and the pressing block 9 are fixedly connected. A vertical rod 16 is fixedly connected to one of the bent rods 11, and a fixing assembly is arranged on the sliding rod 18.

[0023] The fixing assembly includes a first magnet 17 fixedly connected to the end of the sliding rod 18 away from the pressing block 9. A second magnet 4 is fixedly connected to the inner wall of the kettle body 1. When the rotating block 5 rotates to a certain position, the surfaces of the first magnet 17 and the arc-shaped second magnet 4 will be face to face. The magnetism of the face-to-face surfaces of the first magnet 17 and the second magnet 4 is the same, and there is a repulsive force between the first magnet 17 and the second magnet 4. Two symmetrically arranged rotating pieces 15 are fixedly connected to the lower surface of the rotating block 5. The surface of each rotating piece 15 is in contact with the inner wall of the kettle body 1. During the rotation of the two rotating pieces 15 together with the rotating block 5, the rotating pieces 15 can scrape and stir the raw materials adhered to the inner wall of the kettle body 1 and the raw materials near the inner wall of the kettle body 1, so as to make the stirring and mixing of the raw materials more sufficient and thorough.

[0024] A guide ring 8 is fixedly connected to the lower inner wall of the kettle body 1, and the cross-section of the guide ring 8 is arranged in a circular ring shape. A discharge pipe 3 is fixedly connected to the lower surface of the kettle body 1, and a solenoid valve is arranged on the discharge pipe 3. The height of the guide ring 8 surface near the inner wall of the kettle body 1 is higher, and the height of the guide ring 8 surface near the middle of the kettle body 1 is lower. After the stirring and mixing is completed, the solenoid valve is opened, and the raw materials inside the kettle body 1 can slide along the surface of the guide ring 8 and be discharged from the discharge pipe 3. Two arc blocks 10 are fixedly connected to the upper surface of the rotating block 5, and the two arc blocks 10 are arranged symmetrically. The upper surface of the arc block 10 is an arc surface, and the height near the inner wall of the kettle body 1 is lower. When the raw material falls on the arc surface of the arc block 10, the raw material can slide along the arc surface to avoid the raw material from accumulating on the surface of the rotating block 5.

[0025] In the utility model, when in use, appropriate amounts of different raw materials are gradually added to the inside of the two feeding pipes 2 to ensure that there is always sufficient raw material inside the feeding pipes 2. Then, the servo motor drives the rotating shaft 6 to rotate. During the process of the rotating block 5 rotating together with the rotating shaft 6, the T-shaped extrusion block 9 will gradually move against the surface of the vertical rod 16. Under the transmission action of the vertical rod 16 and the bending rod 11, the hollow cylinder 14 and the kettle body 1 rotate relative to each other at the same time. Since one end of the torsion spring 13 is fixedly connected to the inner wall of the kettle body 1 and the other end is fixedly connected to the hollow cylinder 14, the torsion spring 13 is deformed. In the initial state, each sealing cover plate 12 is in contact with the upper inner wall of the kettle body 1, and is located directly below each feeding pipe 2 and seals and blocks it. After the two bending rods 11 rotate, each sealing cover plate 12 will be staggered with the feeding pipe 2, and the raw materials inside each feeding pipe 2 will fall into the inside of the kettle body 1 under the action of gravity.

[0026] When the rotating block 5 rotates to a certain position, the surface of the first magnet 17 and the surface of the arc-shaped second magnet 4 are arranged face to face, and the magnetic properties of the face-to-face surfaces of the first magnet 17 and the second magnet 4 are the same. There is a mutually repulsive force between the first magnet 17 and the second magnet 4. Under the action of the force, the slide bar 18 will shrink toward the inside of the installation cavity. Since the two ends of the first spring 20 are respectively fixedly connected to the slide bar 18 and the fixed plate 19, the first spring 20 is deformed, and the extrusion block 9 will be staggered with the vertical rod 16 after the slide bar 18 moves. Under the elastic force of the torsion spring 13, the hollow cylinder 14 rotates, and the two sealing cover plates 12 will re-seal and block the two feeding pipes 2. By repeating the above process, intermittent multiple automatic unloading of different raw materials can be realized. During the rotation of the stirring rod 7, the raw materials can be stirred and mixed, which has a good mixing effect on the raw materials, can effectively avoid the phenomenon of uneven mixing, and is beneficial to the production of Baohong 4BL pigment.

[0027] In the present utility model, unless otherwise clearly stipulated and defined, terms such as "installation", "connection", "linkage", "fixation" and the like shall be understood in a broad sense.

[0028] As described above, only the preferred specific embodiments of the present utility model are provided, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
