Description

Technical Field

[0001] The utility model relates to the technical field of high-performance epoxy resin production, and more specifically, to a reaction kettle for high-performance epoxy resin production. Background Art

[0002] In the epoxy resin production process, high-performance reactor is one of the key equipment. Its design and operation directly affect product quality and production efficiency. However, the existing high-performance epoxy resin production reactor has a series of problems in the stirring system, stirring rod disassembly and assembly mechanism and reactor cover operation. These problems not only reduce production efficiency, but also may affect the quality of the final product.

[0003] First, regarding the issue of the stirring system, most epoxy resin production reactors use a single stirring rod and a single stirring frame to mix and stir the materials. Although this design is simple, in actual operation, the single stirring rod and stirring frame can easily form a stable vortex in the reactor. This vortex state will cause uneven mixing of materials, affecting reaction efficiency and product quality. Especially in the synthesis process of epoxy resin, the uniform mixing of materials has a vital impact on product performance. The stable vortex state may also cause local overheating or overcooling, affecting the rate and direction of the chemical reaction, thereby affecting the stability and consistency of the final product.

[0004] Secondly, regarding the disassembly and assembly of the stirring rod, the reactor in the prior art is usually designed with a stirring rod fixedly connected to a stirring frame. This design makes the disassembly and assembly of the stirring rod and the stirring frame complicated and time-consuming. During the production process, according to different reaction requirements, it may be necessary to replace stirring rods and stirring frames of different types or sizes. The cumbersome disassembly and assembly process not only prolongs the downtime of the equipment, but also increases production costs. In addition, the complicated disassembly and assembly operations also increase the workload of the operators and reduce work efficiency.

[0005] Furthermore, for the opening and closing operation of the reactor cover, the existing epoxy resin production reactors mostly use manual opening and closing of the reactor cover, which is time-consuming and labor-intensive, thus affecting the reaction process and product quality. A few reactors with an integrated structural design, although to a certain extent, improve the sealing of the equipment, but this design makes the equipment extremely inconvenient when internal inspection, cleaning or maintenance is required, affecting the maintainability of the equipment and the continuity of production.
