Currently, the stirring mechanism is inconvenient to remove for cleaning, and the temperature detection mechanism mainly uses temperature sensors, which are fixedly installed on the inner wall to monitor the reaction temperature. Since the reactants are at different depths, the temperature varies at each reaction depth during the reaction process, making it difficult to control the reaction temperature. Furthermore, the stirring and temperature detection mechanisms are inconvenient to maintain during subsequent use. To address the shortcomings of the existing technology, this utility model provides a sulfonation reaction apparatus for pigment preparation to solve the above problems. Utility Model Content

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] This application provides a sulfonation reaction apparatus for pigment preparation, which solves the problems of existing sulfonation reaction apparatuses for pigment preparation, which typically have complex internal structures requiring the design of stirring and temperature detection structures. Currently, the stirring structure is inconvenient to remove and clean, and the temperature detection structure mainly uses a temperature sensor, which is fixedly installed on the inner wall to monitor the reaction temperature. Since the reactants are at different depths, the temperature at each reaction depth is different during the reaction process, making it difficult to control the reaction temperature. Furthermore, the stirring and temperature detection structures are inconvenient to maintain during subsequent use.

[0041] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0042] Example 1:

[0043] This utility model discloses a sulfonation reaction apparatus for pigment preparation, according to the appendix. Figure 1-5 As shown, it includes a base support 1, a reaction vessel 2, a guide rail frame 3, a movable frame 4, a top cover 5, a lifting unit 6, a support rod 7, and a depth adjustment unit 8;

[0044] The foundation support 1 serves as the supporting base for the entire sulfonation reaction unit, providing a stable installation platform for other components and ensuring the overall stability of the unit during operation.

[0045] The reaction vessel 2 is mounted on the base support 1. The reaction vessel 2 is used to contain the raw materials required for the sulfonation reaction and to provide a space for the reaction. The reaction vessel 2 is equipped with an electric heating jacket 21 and a jacket 22 for cooling the reactants. Circulating water pipes 23 are provided on both sides of the jacket 22.

[0046] The electric heating jacket 21 installed on the reaction vessel 2 can convert electrical energy into heat energy to heat the reactants in the reaction vessel 2 to meet the temperature conditions required for the sulfonation reaction; the jacket 22 is used to cool the reactants, and the cooling water circulating in the circulating water pipe 23 carries away the heat generated during the reaction to prevent the reaction temperature from being too high.

[0047] When the device is in use, the raw materials required for the sulfonation reaction are added to the reaction vessel 2. Depending on the reaction requirements, the temperature is raised by the electric heating jacket 21 or cooled by the jacket 22 and the circulating water pipe 23 to control the reaction temperature within a suitable range.

[0048] The guide rail frame 3 is set on the base support 1. The guide rail frame 3 provides a sliding track for the movable frame 4, so that the movable frame 4 can move up and down along the guide rail frame 3, thereby realizing the lifting function of the upper cover 5.

[0049] The movable frame 4 is attached to the guide rail 3 and can move up and down along the guide rail 3, driving the upper cover 5 to rise and fall together, so as to realize the docking and separation of the upper cover 5 and the reaction vessel 2.

[0050] The top cover 5 is mounted on the movable frame 4 and is used to connect with the top of the reaction vessel 2 to seal the reaction vessel 2 and prevent material leakage during the reaction. At the same time, the top cover 5 is equipped with a stirring structure 51, which can stir the reactants in the reaction vessel 2 to ensure that the reactants are fully mixed and improve the reaction efficiency.

[0051] The lifting unit 6 is mounted on the guide rail 3 and is used to adjust the height of the movable frame 4 and the upper cover 5; the lifting unit 6 includes:

[0052] Electric push rod 61 is mounted on guide rail frame 3;

[0053] The lifting block 62 is located at the output end of the electric push rod 61 and is fixedly connected to the movable frame 4.

[0054] The lifting unit 6 drives the lifting block 62 to move up and down through the telescopic movement of the electric push rod 61. Since the lifting block 62 is fixedly connected to the movable frame 4, the height of the movable frame 4 and the upper cover 5 can be adjusted.

[0055] The support rod 7 is movably attached to the upper cover 5, and a temperature sensor 71 is installed on the support rod 7; the support rod 7 can move to a certain extent along the upper cover 5. The temperature sensor 71 on the support rod 7 is used to monitor the temperature at different locations inside the reaction vessel 2 in real time, so as to adjust the reaction temperature in a timely manner.

[0056] A depth adjustment unit 8 is mounted on the upper cover 5 and is used to adjust the position of the support rod 7. Under the action of the depth adjustment unit 8, the position of the support rod 7 is adjusted so that the temperature sensor 71 can penetrate into the reaction vessel 2 at different depths to monitor temperature changes in real time.

[0057] The depth adjustment unit 8 includes:

[0058] Limit bracket 81 is installed on the upper cover 5;

[0059] The adjusting platform 82 is slidably connected to the limiting frame 81;

[0060] The second motor 83 is mounted on the limit frame 81;

[0061] The lead screw 84 is located at the output end of the second motor 83 and is threadedly connected to the adjustment table 82.

[0062] When the depth adjustment unit 8 is in operation, the second motor 83 starts and drives the lead screw 84 to rotate. Since the adjustment table 82 is threadedly connected to the lead screw 84 and the adjustment table 82 is slidably connected to the limit frame 81, the rotation of the lead screw 84 will cause the adjustment table 82 to move up and down along the limit frame 81, thereby driving the support rod 7 to move up and down, and realizing the adjustment of the position of the temperature sensor 71.

[0063] Therefore, according to the reaction requirements, the second motor 83 is started, and the rotation of the lead screw 84 drives the adjustment table 82 and the support rod 7 to move up and down, adjusting the temperature sensor 71 to a suitable position, so that the device can easily monitor the temperature information at various depth positions and ensure the reaction effect of the sulfonation reaction device.

[0064] Example 2:

Figure 1-5 As shown, it includes a base support 1, a reaction vessel 2, a guide rail frame 3, a movable frame 4, a top cover 5, a lifting unit 6, a support rod 7, and a depth adjustment unit 8;

[0066] The reaction vessel 2 is mounted on the foundation support 1;

[0067] The guide rail frame 3 is mounted on the base support 1;

[0068] The movable frame 4 is attached to the guide rail frame 3;

[0069] The top cover 5 is mounted on the movable frame 4 and is used to dock with the top of the reaction vessel 2. The top cover 5 is equipped with a stirring structure 51.

[0070] The lifting unit 6 is mounted on the guide rail frame 3 and is used to adjust the height of the movable frame 4 and the upper cover 5;

[0072] The depth adjustment unit 8 is located on the upper cover 5 and is used to adjust the position of the support rod 7.

[0073] The bottom of the reaction vessel 2 is equipped with a discharge pipe 24, and a valve body 25 is installed on the discharge pipe 24. The discharge pipe 24 and the valve body 25 are used to discharge the material after the reaction is completed.

[0074] The temperature sensor 71 has a screw hole, and the temperature sensor 71 is threadedly connected to the end of the support rod 7. The threaded connection between the temperature sensor 71 and the support rod 7 makes it easy to disassemble and assemble the temperature sensor 71 and facilitates maintenance.

[0075] The stirring structure 51 includes:

[0076] The first motor 511 is mounted on the upper cover 5;

[0077] The stirring rod 512 is located at the output end of the first motor 511. The stirring structure 51 has a compact structure, is easy to operate, and runs stably.

[0078] A sealing unit 9 is provided between the reaction vessel 2 and the top cover 5. The sealing unit 9 includes:

[0079] The first docking plate 91 is mounted on the upper cover 5;

[0080] The second docking plate 92 is disposed on the reaction vessel 2, and a rubber ring is movably engaged between the first docking plate 91 and the second docking plate 92. The sealing unit 9 uses the first docking plate 91 and the second docking plate 92 to compress and seal the rubber ring, which has a good sealing effect, effectively prevents material leakage during the reaction process, ensures the purity of the reaction environment, and also improves the safety of the device.
