Description
Technical Field
[0001] This utility model relates to the technical field of resin production equipment, and in particular to a multi-purpose, easy-to-switch integrated resin reactor. Background Technology
[0002] Resins are one of the core basic materials of modern industry and materials science. They generally refer to a class of polymer compounds obtained by chemically linking small molecule monomers into long chain or network macromolecular structures. In existing technologies, the preparation process of synthetic resins usually involves a series of key technical steps. A suitable specific reaction vessel is particularly crucial in the resin synthesis process. A chemical reaction vessel is a comprehensive reaction container, and its structure generally consists of a vessel body, transmission device, stirring device, heating device, cooling device, and sealing device. A reaction vessel system is a system composed of a reaction vessel and corresponding auxiliary equipment, such as condensers, packed towers, water separators, and collection tanks, depending on different process requirements. Currently, a reaction vessel system usually only has one function; for example, a system consisting of a reaction vessel, condenser, water separator, and collection tank can only perform distillation.
[0003] However, there are many types of resins, such as acrylic resins, epoxy resins, alkyd resins, and phenolic resins. Different resins require different preparation methods, necessitating the construction of different reactor systems. To improve resin performance, modifications such as grafting, crosslinking, and blending are often necessary. Different modifications also require different reactors, especially since some resin preparation processes require multiple replacements of reactor components, impacting efficiency and consistency in both experiments and production. Furthermore, multiple systems occupy a large area; therefore, improving land resource utilization through multifunctional design is a crucial challenge that factories must address.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0016] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a multi-purpose, easy-to-use, integrated resin reactor includes a circulating hot oil system 1.

The reactor lid 18 is snapped onto the top of the reactor 2. A stirrer connection port 6 is provided in the center of the top of the reactor lid 18, and a stirrer 19 is installed in the center of the stirrer connection port 6. The bottom end of the stirrer 19 is connected to the bottom of the reactor 2. A stirring motor 3 is installed on the top of the reactor lid 18. The output end of the stirring motor 3 is connected to the stirrer 19. There are multiple stirring motors 3, which are respectively distributed on the top of the reactor 2, the top of the dropping vessel 20, and the top of the other vessel. The stirring motors 3 are arranged correspondingly to the stirrers 19. The top is provided with a first feed inlet 4, an air outlet 5, an observation and sampling port 7, an air inlet 8 and a second feed inlet 9, and the mixer connection port 6 is located in the middle of the first feed inlet 4, the air outlet 5, the observation and sampling port 7, the air inlet 8 and the second feed inlet 9.

Opening the first three-way valve 26 and the second three-way valve 28 allows switching between the two valves to select the reaction system mode, including titration and reflux, titration and condensation, pre-treatment addition and reflux, and pre-treatment addition and condensation. This switching can be done quickly and conveniently during the reaction without replacing the reactor 2 or accessories, ensuring the continuity of the reaction and preventing product contamination. The dripping vessel 20 and the pre-treatment vessel 21 are connected to the reactor via their bottom outlets. 2. After the pre-mixing, stirring, and heating of the titrant or pre-material are completed in the dropping vessel 20 and the pre-mixing vessel 21, the time and speed of addition to the reaction vessel 2 can be freely selected by controlling the control valve in the discharge port at the bottom of the dropping vessel 20 and the pre-mixing vessel 21. The convenient switching can meet the complex reaction conditions of different resins. When the system is in use, the gas system 32, the circulating hot oil system 1, the vacuum pump 24 and the circulating water cooling system 29 can be freely opened and closed, and switched according to different resin types and reaction conditions. The connection method of the dropping vessel 20 and the pre-mixing vessel 21 is the same as that of the reaction vessel 2. The details of the vessel cover and the vessel body are different. The vessel cover of the dropping vessel 20 and the pre-mixing vessel 21 has only five ports. Among them, the connection port 22 is used as the connection port of the stirrer 19 and the stirring motor 3. The other four ports are stirrer connection ports 23. They are the same size and symmetrical to each other. Any port can be used as a temperature control port, a feed port, an observation and sampling port and an air inlet.
