Description

Technical Field

[0001] This utility model relates to the field of polypropylene nucleating agent production technology, and more specifically, to a reaction apparatus for producing polypropylene nucleating agents. Background Technology

[0002] Polypropylene nucleating agents are important modifying additives for polypropylene (PP). They accelerate crystallization and refine grain size by altering PP's crystallization behavior. They are mainly classified into α-crystalline and β-crystalline nucleating agents, including inorganic, organic, and polymeric types. Preparation methods are diverse, such as chemical reaction synthesis. Applications include improved transparency, surface gloss, mechanical and thermal properties, and enhanced processing performance. Future development trends emphasize high efficiency, environmental friendliness, and multifunctionality. The production of polypropylene nucleating agents requires reaction equipment.

[0003] In conventional reaction equipment, materials are first placed inside the device, then a crushing mechanism breaks down the solids. A stirrer then moves the materials, ensuring thorough mixing between the solids and the solution. However, because some solids have densities different from the solution upon entering the device, sedimentation occurs, causing the solids to settle at the bottom. While the crushing mechanism mixes the solids with the solution at the bottom, the solution in the upper part of the device fails to mix evenly with the solids. This results in uneven mixing of solids and liquids within the device, necessitating modification and optimization. Utility Model Content

The annular frame 2 is fixedly disposed above the bottom column 1, and the reaction vessel 3 is fixedly sleeved inside the annular frame 2.

[0025] A connecting column 10 is fixedly installed on the top of the inner side of the reaction vessel 3. A shell 11 is fixedly installed on the bottom of the connecting column 10. A bevel gear 13 is rotatably installed on the top of the inner side of the shell 11. Bevel gears 14 are rotatably installed on both sides inside the shell 11. Bevel gears 13 and 14 mesh with each other. A rotating shaft 15 is fixedly installed on one side of the bevel gear 14. One end of the rotating shaft 15 extends to the outside of the shell 11. A stirring blade 16 is fixedly sleeved on the outer surface of the rotating shaft 15. A stirring blade 17 is fixedly sleeved on one end of the rotating shaft 15.

[0026] When the operator uses the equipment, they first start the stirring motor 9 via the controller 4. When the stirring motor 9 starts, it drives the rotation of the rotating shaft 12. When the rotating shaft 12 rotates, it drives the rotation of the bevel gear 13. When the bevel gear 13 rotates, it meshes with the bevel gear 14, so the rotation of the bevel gear 13 drives the rotation of the bevel gear 14. When the bevel gear 14 rotates, it drives the rotation of the rotating shaft 15. When the rotating shaft 15 rotates, it drives the rotation of the stirring blades 16 and 17, thereby fully mixing the solid and liquid inside the reaction vessel 3.

[0027] By starting the stirring motor 9, the rotating shaft 12 is driven to rotate, which in turn drives the bevel gear 14 to rotate. When the bevel gear 14 rotates, it drives the stirring blades 16 and 17 to rotate. Compared with traditional devices, this device uses the rotation of the stirring blades 16 and 17 to stir the solids and liquids inside the device vertically. Compared with other devices, the device uses the rotation of the impeller 19 and the emulsifying stirrer 23 to stir the solids and solutions. This device can stir the upper and lower layers of solids and solutions, as well as the horizontal layers of solids and solutions, thereby improving the efficiency of stirring and reaction. This allows the solids and solutions to mix quickly, thus improving the efficiency of the device's reaction.

Compared with the traditional device, this device cleans the inner wall of the reaction tank 3 by rotating the cleaning plate 26. Compared with the traditional device, which directly rinses with water, this device can clean the inner wall of the reaction tank 3 more efficiently and can clean the inner wall of the reaction tank 3 as a whole, thereby avoiding affecting the purity of the solution in the next use.

[0031] The reaction vessel 3 is fixedly mounted with a stirring motor 9 on top. A rotating shaft 12 is fixedly mounted on the bottom of the stirring motor 9.

A protective shell 8 is fixedly mounted on top of the reaction vessel 3. The protective shell 8 is located outside the stirring motor 9.

[0032] The controller 4 starts the stirring motor 9, which drives the rotating shaft 12 to rotate. As the rotating shaft 12 rotates, it drives the bevel gear 13 to rotate.

[0033] The crushing mechanism includes a connecting roller 18 fixedly disposed at the bottom of the bevel gear 13.

The bottom of the impeller 19 is fixedly connected to the rotating plate 24, and an agitator 20 is fixedly mounted at the bottom of the rotating plate 24.

[0034] The rotation of the bevel gear 13 drives the rotation of the connecting roller 18, which in turn drives the rotation of the impeller 19, thus crushing the solids at the bottom of the inner side of the device.

[0035] An emulsifier motor 22 is fixedly installed on the top of the reaction tank 3. One end of the drive shaft of the emulsifier motor 22 extends into the interior of the reaction tank 3 and is fixedly installed with an emulsifying stirrer 23. A protective shell 21 is fixedly installed on the top of the reaction tank 3, and the protective shell 21 is located outside the emulsifier motor 22.

[0036] The emulsifier motor 22 is started by the controller 4 to drive the rotation of the emulsifying stirrer 23, thereby mixing the solids and solutions inside the device.

[0037] The reaction tank 3 has a feeding port 5 at the top, a jacket 7 is fixedly sleeved on the bottom outside of the reaction tank 3, and a discharge valve 6 is fixedly installed at the bottom of the reaction tank 3.

[0040] The design of controller 4 controls the operation of the device, thereby improving the safety of the device during operation.

[0041] Working principle and usage process of this utility model:

[0042] When the operator uses the equipment, they first start the stirring motor 9 via the controller 4. When the stirring motor 9 starts, it drives the rotation of the rotating shaft 12. When the rotating shaft 12 rotates, it drives the rotation of the bevel gear 13. When the bevel gear 13 rotates, it meshes with the bevel gear 14, so the rotation of the bevel gear 13 drives the rotation of the bevel gear 14. When the bevel gear 14 rotates, it drives the rotation of the rotating shaft 15. When the rotating shaft 15 rotates, it drives the rotation of the stirring blades 16 and 17, thereby fully mixing the solid and liquid inside the reaction vessel 3.

[0043] When the operator uses the device, they first start the stirring motor 9 via the controller 4 to drive the rotating shaft 12 to rotate. When the rotating shaft 12 rotates, it drives the bevel gear 13 to rotate. As the bevel gear 13 rotates, it drives the connecting roller 18 to rotate. When the connecting roller 18 rotates, it drives the rotating plate 24 to rotate. When the rotating plate 24 rotates, it drives the connecting plate 25 to rotate. When the connecting plate 25 rotates, it drives the cleaning plate 26 to rotate. As the cleaning plate 26 rotates, it cleans the inner wall of the reaction vessel 3.
