Description

Technical Field

[0001] The utility model relates to the technical field of ion exchange resin production, in particular to a reaction kettle for ion exchange resin production. Background Art

[0002] The raw materials for the matrix manufacturing of ion exchange resins mainly include styrene and acrylic acid (ester). They react with the cross-linking agent divinylbenzene to form a polymer with a network skeleton structure of a long molecular main chain and cross-linked cross chains. Styrene resins are used first, and acrylic resins are used later. The adsorption properties of these two types of resins are very good, but they have different characteristics. Acrylic resins can exchange and adsorb most ionic pigments, have a large decolorization capacity, and the adsorbate is easier to elute, which is convenient for regeneration. They can be used as the main decolorization resin in sugar factories. Styrene resins are good at adsorbing aromatic substances and polyphenol pigments in sugar juice (including negatively charged or uncharged ones), but they are difficult to elute during regeneration. Therefore, the sugar solution is first roughly decolorized with acrylic resin and then finely decolorized with styrene resin, which can give full play to the advantages of both. With the continuous development of society, the production and processing of ion exchange resins are increasing, and more and more equipment is used in its production and processing.

[0003] Publication No. CN215963590U discloses a reactor for the production and processing of ion exchange resin, including a reactor, wherein the inner side of the reactor is rotatably connected to an inner tank, the inner side of the inner tank is provided with an agitator, and the agitator runs through the reactor, the agitator is fixedly connected to the reactor, the outer side of the stirring rod of the agitator is fixedly connected to a driving gear, the outer side of the driving gear is meshed and connected to a driven gear, the outer side of the driven gear is meshed and connected to a gear ring, the outer side of the gear ring is fixedly connected to a fixed ring, and the fixed ring is fixedly connected to the inner tank. Although this type of reactor ensures the uniformity of the polymerization reaction and improves the efficiency of stirring, thereby improving the production and processing efficiency of the ion exchange resin. However, when the drive motor of the existing reactor is damaged, the replacement process is cumbersome, the maintenance time is long, and the production cost and time cost are increased. In addition, the installation and disassembly process of the motor often requires special tools and skills, and the operation is difficult, which is not conducive to the rapid maintenance and replacement of the on-site staff. These problems limit the use efficiency and flexibility of the reactor equipment. Therefore, improvements are needed. Utility Model Content

A vertical rod 8 is also fixedly mounted on the top of the reactor body 1 . The vertical rod 8 is fixed to the reactor body 1 by bolts or welding to provide a sliding track for the side block A11 .

[0027] See also Figure 1-6, the top of the reactor body 1 is also rotatably connected with a threaded rod 9 through a bearing, and the threaded rod 9 can rotate freely on the reactor body 1, but its position is fixed. The surface of the vertical rod 8 is sleeved with a slidable side block A11, and a hole matching the vertical rod 8 is provided inside the side block A11, so that it can slide freely on the vertical rod 8. The surface of the threaded rod 9 is threadedly connected with a side block B12, and the threaded hole provided inside the side block B12 cooperates with the threaded rod 9 to achieve a threaded connection. The side of the side block A11 and the side block B12 is fixedly installed with a motor 10 by bolts, and the output end of the motor 10 is installed with a spline sleeve 13, and the spline sleeve 13 is connected with the output shaft of the motor 10 by a key to ensure that the two rotate synchronously. The bottom surface of the side block A11 and the side block B12 is also fixedly installed with a guide cover 14, and the guide cover 14 adopts a trumpet-shaped structure, and the vertical rod 8 and the threaded rod 9 can be easily inserted through the guide cover 14.

[0028] Embodiment 2

[0029] See also Figure 5-6 , the surface of the rotating rod 5 is provided with a stirring mechanism, and the stirring mechanism includes a slide bar 15, which is fixedly mounted on the rotating rod 5 to provide a stable sliding track for the stirring blade B16. The stirring blade B16 is slidably connected to the slide bar 15 through the annular groove 17 opened on its top surface. Such a design not only ensures that the stirring blade B16 can rotate with the rotation of the rotating rod 5, but also can slide freely up and down on the slide bar 15. In order to realize the up and down sliding function of the stirring blade B16, an electric push rod 18 is fixedly installed on the top of the reactor body 1. The output end of this electric push rod 18 is connected to a lifting rod 19, and the material of the lifting rod 19 is austenitic stainless steel, which is both strong and corrosion-resistant, and is very suitable for use in such chemical equipment. The end of the lifting rod 19 is slidably connected to the annular groove 17 on the stirring blade B16, so that when the electric push rod 18 is working, it can accurately drive the stirring blade B16 to slide on the slide bar 15, thereby adjusting the stirring height.

[0030] Working principle: the spline sleeve 13 on the motor 10 is sleeved on the surface of the spline shaft 7, the motor 10 can drive the spline sleeve 13 to rotate, the spline sleeve 13 can then drive the spline shaft 7 to rotate, the spline shaft 7 then drives the rotating shaft 4 to rotate, the rotating shaft 4 then drives the rotating rod 5 to rotate, the rotating rod 5 then drives the stirring blade A6 to rotate, at this time, the ion exchange resin raw material in the reactor body 1 can be mixed by the stirring blade A6, so as to ensure the uniformity of the polymerization reaction, and at the same time, when the motor 10 is damaged after working for a long time, the staff can twist the threaded rod 9, at this time, since the inside of the side block B12 is provided with a thread, the threaded rod 9 can drive the side block B12 to move, and the side block B12 can then drive the motor 10 to move, when the side block B12 and the side block A11 are both detached When the motor 10 is separated from the threaded rod 9 and the vertical rod 8, the motor 10 can be removed at this time. When installing a new motor 10, it is only necessary to align the side block A11 and the side block B12 on the motor 10 with the vertical rod 8 and the threaded rod 9, and then twist the threaded rod 9. At this time, the threaded rod 9 drives the side block B12 to be inserted. After the motor 10 is completely inserted, the motor 10 can drive the spline sleeve 13 to be inserted into the spline shaft 7. At this time, the rotating rod 5 can be connected, and then the rotating rod 5 and the stirring blade A6 can be driven by the motor 10 to rotate for stirring, thereby completing the replacement of the motor 10. The utility model can efficiently and evenly mix the ion exchange resin raw materials in the reactor through the linkage design of the motor 10, the spline sleeve 13, the spline shaft 7, the rotating shaft 4, the rotating rod 5 and the stirring blade A6 to ensure the polymerization. The uniformity of the reaction is improved, thereby improving the product quality. When the motor 10 is damaged after working for a long time, the motor 10 can be easily moved and replaced through the threaded connection between the threaded rod 9 and the side block B12, which greatly reduces the maintenance time and cost. The design of the reactor allows the motor 10 to be quickly replaced when it is damaged. This modular design improves the flexibility and maintainability of the equipment. The installation and removal process of the motor 10 is simple and clear. It only needs to align the vertical rod 8 and the threaded rod 9, and then screw the threaded rod 9 to complete the fixing or removal of the motor 10. No special tools or skills are required, which reduces the difficulty of operation. The electric push rod 18 can drive the lifting rod 19 to move, and the lifting rod 19 can then drive the stirring blade B16 downward or upward on the surface of the slide bar 15. The surface slides up and down, and the stirring height of the stirring blade B16 can be controlled by the electric push rod 18. In this way, the optimal stirring height can be controlled according to the amount of material loaded, so as to avoid empty stirring due to too little material. Moreover, since the lifting rod 19 can slide in the annular groove 17, the rotating rod 5 can normally drive the stirring blade B16 to rotate. The utility model can accurately control the stirring height of the stirring blade B16 through the drive of the electric push rod 18, so that the equipment can adjust the stirring height according to the amount of materials in different batches, thereby optimizing the stirring effect. In traditional stirring equipment, when the amount of material is insufficient, the agitator may idle, causing energy waste and equipment wear. This design can adjust the height of the stirring blade B16 to avoid empty stirring when the material is too little.
