Abstract
Description
Technical Field
[0001] This utility model relates to the field of catalyst preparation technology, specifically a high-precision catalyst preparation device for TCPP. Background Technology
[0002] TCPP, or tris(2-chloropropyl) phosphate, is an important additive flame retardant widely used in plastics, rubber, and fibers to improve their flame retardant properties. The catalyst used in the preparation of TCPP plays a crucial role in the reaction rate, product purity, and yield. A suitable catalyst can effectively lower the activation energy of the reaction, allowing the reaction to proceed under milder conditions, thereby improving production efficiency and ensuring product quality.
[0003] Currently, the industrial preparation of TCPP catalysts mostly employs conventional equipment combining batch reactors with mechanical stirring. This type of equipment suffers from a core defect: uneven solid-liquid mixing. The design of the mechanical stirring paddle makes it difficult to achieve sufficient shearing of high-viscosity slurries, resulting in insufficient dispersion of the catalyst precursor in the liquid phase and a tendency to form localized agglomerations. This problem leads to uneven distribution of active components, excessively large crystallite size, and ultimately reduces the catalyst's specific surface area and reactivity. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-4 A high-precision catalyst preparation device for TCPP includes a vessel body 1. A top cover 2 is bolted to the top of the vessel body 1. A gantry frame 3 is fixedly connected to the top surface of the top cover 2. A large gear 4 and a small gear 7 are rotatably connected to the top of the gantry frame 3. A shaft 5 is fixedly connected to the bottom surface of the large gear 4. A cam 6 is fixedly connected to the outer surface of the shaft 5. A transmission rod 8 is inserted into the inside of the small gear 7. A rotating rod 9 is fixedly connected to the bottom end of the transmission rod 8. A sliding member 10 is rotatably connected to the outer surface of the rotating rod 9. A connecting plate 11 is fixedly connected to the outer wall of the sliding member 10. A limit rod 12 is fixedly connected to one end of the connecting plate 11. A stirring paddle 13 is fixedly connected to the bottom end of the rotating rod 9.
[0022] Specifically, the top surface of the top cover 2 is fixedly connected to the feed pipe 14, and the bottom of the vessel body 1 is connected to the discharge valve 15 by bolts.
[0023] The advantage is that the raw materials for catalyst preparation are added into the interior of the reactor body 1 through the feed pipe 14. After the raw materials are fully mixed and dissolved inside the reactor body 1, the mixed solution can be discharged by opening the discharge valve 15.
[0024] Specifically, a small sprocket 16 is fixedly connected to the top surface of the large gear 4, a top plate 17 is fixedly connected to the side of the gantry 3, a drive rod 18 is rotatably connected inside the top plate 17, a large sprocket 24 is fixedly connected to the top of the drive rod 18, and a drive motor 19 is connected to the bottom of the drive rod 18.
[0025] Specifically, the large gear 4 meshes with two small gears 7. The top surface of the small gears 7 has a keyway. A key bar is fixedly connected to the outer wall of the transmission rod 8. The key bar is mechanically engaged with the keyway of the small gears 7.
[0026] Specifically, the sliding component 10 includes a cylindrical body 101, a pin 102 fixedly connected to the outer wall of the cylindrical body 101, a pulley 103 rotatably connected to one end of the pin 102, the pulley 103 slidingly contacting the cam 6, a bearing embedded inside the cylindrical body 101, and a rotating rod 9 rotatably connected inside the bearing.
[0027] When various raw materials are added into the vessel body 1, the drive motor 19 is activated to rotate the large sprocket 24. The large sprocket 24 then drives the small sprocket 16 via a chain. The small sprocket 16 drives the large gear 4, which in turn drives two small gears 7. The small gears 7 drive the transmission rod 8, which in turn drives the rotating rod 9. The rotating rod 9 then drives the stirring paddle 13. In this way, the stirring paddle 13 mixes the various raw materials inside the vessel body 1. At the same time, the large gear 4 also drives the shaft 5 to rotate, which in turn drives the cam 6 to rotate. During the rotation of the cam 6... The pulley 103 will roll on its edge. Since the limiting rod 12 is inserted into the top cover 2 and is fixedly connected to the cylinder 101, and the outer surface of the cylinder 101 is fixedly connected to the pin 102, the cylinder 101 will move up and down with the pulley 103. The cylinder 101 will then drive the rotating rod 9 and the transmission rod 8 to move up and down. In this way, the stirring paddle 13 can move up and down repeatedly while rotating. The two sets of stirring paddles 13 move up and down alternately, which can accelerate the dissolution and mixing of the materials and greatly improve the efficiency of mixing and dissolving.
[0028] Specifically, a spiral heating tube 20 is fixedly connected to the inner wall of the vessel body 1. One end of the spiral heating tube 20 is fixedly connected to a heat medium inlet pipe 21, and the other end of the spiral heating tube 20 is fixedly connected to a heat medium outlet pipe 22. A temperature sensor 23 is installed on the top surface of the top cover 2, and the probe of the temperature sensor 23 extends into the interior of the vessel body 1.
[0029] The advantages are that the inner wall of the vessel body 1 is equipped with a spiral heating tube 20, which, together with the heat medium inlet pipe 21 and the heat medium outlet pipe 22, can heat the materials inside the vessel body 1. During the catalyst preparation process, heating can promote the chemical reaction between raw materials, increase the reaction rate, and make the reaction more complete, which helps to improve the quality of the catalyst. The temperature sensor 23 installed on the top surface of the top cover 2 has its probe extending into the inside of the vessel body 1, which can monitor the temperature inside the vessel in real time. By monitoring the temperature, the flow rate of the heat medium or the reaction conditions can be adjusted in a timely manner to avoid the adverse effects of excessively high or low temperatures on the reaction. For example, it can prevent the decomposition of raw materials or the occurrence of side reactions due to excessively high temperatures, and also prevent the reaction from being too slow due to excessively low temperatures. This ensures that the catalyst preparation process is carried out in a suitable temperature environment, further ensuring product quality and reaction efficiency.
[0030] In use, the catalyst preparation raw materials are added to the inside of the reactor body 1 through the feed pipe 14; then the drive motor 19 is started, which drives the large sprocket 24 to rotate. The large sprocket 24 drives the small sprocket 16 to rotate via a chain. The small sprocket 16 drives the large gear 4 to rotate. The large gear 4 drives the two small gears 7 to rotate. The small gears 7 drive the transmission rod 8 to rotate. The transmission rod 8 drives the rotating rod 9 to rotate. The rotating rod 9 drives the stirring paddle 13 to rotate, mixing the raw materials in the reactor body 1. At the same time, the large gear 4 also drives the shaft 5 to rotate. The shaft 5 drives the cam 6 to rotate. The cam 6 drives the pulley 103 to roll on its edge. Due to the limiting rod 1... 2 is fixedly connected to the cylinder 101. The cylinder 101 moves up and down with the pulley 103, which in turn drives the rotating rod 9 and the transmission rod 8 to move up and down, so that the stirring paddle 13 moves up and down repeatedly while rotating, which accelerates the dissolution and mixing of materials. According to the actual reaction requirements, the heating medium is introduced into the spiral heating tube 20 through the heating medium inlet pipe 21 to heat the materials in the vessel 1. The heating medium is discharged from the heating medium outlet pipe 22. The temperature sensor 23 installed on the top surface of the top cover 2 is used to monitor the temperature in the vessel in real time and adjust the reaction conditions in time. After all the raw materials are fully mixed and dissolved in the vessel 1, the discharge valve 15 is opened to discharge the mixed solution.
