[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-5This utility model provides an improved external coil reactor for resin production, including a reactor body 1 and a reactor cover 2 disposed on the top of the reactor body 1. Three support legs 3 arranged at equal angles are fixedly connected to the bottom of the reactor body 1. A feed pipe 4 is fixedly connected to the reactor cover 2. Multiple vertically arranged annular external coils 5 are disposed on the outer circumference of the reactor body 1. Four mounting rods 6 arranged at equal arcs are also fixedly installed on the outer circumference of the reactor body 1 by screws. Each mounting rod 6 has an arc-shaped clip that matches the annular external coil 5. The groove 601, each annular outer coil 5 is snapped into the arc-shaped groove 601 of the corresponding mounting rod 6, and two symmetrically arranged connectors 7 are fixedly connected to each annular outer coil 5. The corresponding connectors 7 of two adjacent annular outer coils 5 are connected by a connecting pipe 8. A stirring mechanism 9 is fixedly installed on the lid 2. The stirring part of the stirring mechanism 9 extends into the inner cavity of the vessel body 1. A discharge pipe 10 is fixedly connected to the bottom of the vessel body 1. A discharge bend 11 with a solenoid valve is fixedly installed on the discharge pipe 10.

[0022] The improved external coil reactor for resin production firstly features four equally arc-shaped mounting rods 6 on the outer circumference of the reactor body 1, with arc-shaped slots 601 on them. This allows the annular external coil 5 to be directly engaged in the arc-shaped slots 601, and the mounting rods 6 are fixed to the reactor body 1 with screws. When cleaning, inspection, or replacement of the annular external coil 5 is required, simply loosen the screws fixing the mounting rods 6 to remove the entire mounting rod 6 and then remove the annular external coil 5. The operation is simple and quick, without the need for welding equipment or complex disassembly of the reactor body, significantly shortening downtime, reducing labor and equipment costs, thereby improving equipment availability and production continuity. Furthermore, the external coil system adopts a modular design, facilitating the replacement of individual components and overall assembly and transportation. Secondly, multiple annular outer coils 5 are arranged vertically at equal intervals, covering most of the outer surface of the vessel body 1, increasing the heat transfer area. Then, the connectors 7 of adjacent annular outer coils 5 are connected in series through connecting pipes 8 to form a continuous fluid channel, allowing the heat transfer medium (heat transfer oil or cooling water) to flow through all annular outer coils 5 in sequence. Combined with the stirring mechanism 9 on the vessel lid 2, this ensures thorough mixing of the materials inside the vessel. Combined with uniform external heating / cooling, the reaction conditions are optimized, ensuring a more uniform temperature in different height areas of the vessel body 1 and avoiding local overheating or overcooling. This is crucial for the reaction of temperature-sensitive materials such as resins, and helps to improve product quality and reaction stability. Finally, the discharge pipe 10 has a discharge bend 11 with a solenoid valve, which enables the discharge process to be linked with the control system, easily realizing automated production.

[0023] Both the top of the reactor body 1 and the reactor cover 2 are fixedly connected to connecting flanges 13. The two connecting flanges 13 are fixed together with bolts, which facilitates the disassembly and installation of the reactor cover 2, and makes it convenient to clean and maintain the inside of the reactor body 1, as well as the stirring mechanism 9 installed on the reactor cover 2. At least two mounting pipes 14 are fixedly connected to the reactor cover 2, which communicate with the inner cavity of the reactor body 1. The mounting pipes 14 can be used to install various auxiliary equipment, such as temperature sensors, pressure sensors, air inlet pipes, and exhaust pipes, to meet the needs of monitoring and controlling reaction conditions during resin production.

[0024] The stirring mechanism 9 includes a stirring motor 901, a stirring rod 902, and a stirring blade 903. The stirring motor 901 is fixedly mounted on the vessel cover 2, and the stirring rod 902 is fixedly mounted on the output shaft of the stirring motor 901. The stirring rod 902 extends into the inner cavity of the vessel body 1, and the stirring blade 903 is fixedly mounted on the stirring rod 902. The stirring blade 903 adopts an anchor structure. The stirring motor 901 drives the stirring rod 902 to rotate, which in turn drives the anchor stirring blade on it to rotate, stirring the resin production materials in the vessel body 1, so that the materials are fully mixed, promoting the uniform reaction, improving reaction efficiency and product quality.

[0025] The annular outer coil 5 has a semi-circular cross-section, and its flat side is tightly attached to the outer circumference of the vessel body 1. This increases the contact area between the annular outer coil 5 and the vessel body 1, facilitating more efficient heat transfer between them and improving heat exchange efficiency, thereby better controlling the reaction temperature inside the vessel body 1. The annular outer coil 5 is a two-section structure consisting of two semi-circular coils 501. Both ends of the two semi-circular coils 501 are fixedly connected to semi-circular flanges 12. Adjacent semi-circular flanges 12 are bolted together, facilitating the installation and disassembly of the annular outer coil 5. During installation, the two semi-circular coils 501 can be placed in suitable positions before assembly. Disassembly is also more convenient, facilitating cleaning, inspection, or replacement of the annular outer coil 5.

[0026] The mounting rod 6 is a multi-segment structure comprising multiple mounting blocks 602 corresponding to each annular outer coil 5. All mounting blocks 602 are fixed to the outer circumferential surface of the vessel body 1 by screws. Each mounting block 602 has an arc-shaped slot 601. When cleaning, inspecting, or replacing a particular annular outer coil 5, simply remove the mounting block 602 securing that coil, then disassemble and remove the two semi-circular coils 501. This design offers greater flexibility and ease of operation. Each arc-shaped slot 601 contains a heat-resistant rubber pad 15, ensuring that the annular outer coil 5 fits snugly against the outer circumferential surface of the vessel body 1 when inserted into the slot, guaranteeing excellent heat exchange performance.

[0027] Meanwhile, rubber gaskets are installed between the two connecting flanges 13, the two semi-circular flanges 12, the connector 7, and the connecting pipe 8 to ensure a good sealing effect.

[0028] When using the improved external coil reactor for resin production, auxiliary equipment such as temperature sensors, pressure sensors, air inlet pipes, and exhaust pipes are installed on the mounting pipe 14 on the reactor cover 2 according to production needs. The unused connector 7 on the lowest annular external coil 5 is connected to the input end of the heat transfer medium, and the unused connector 7 on the highest annular external coil 5 is connected to the output end of the heat transfer medium. The raw materials required for resin production are accurately added into the inner cavity of the reactor body 1 through the feed pipe 4 on the reactor cover 2. The stirring mechanism 9 installed on the reactor cover 2 is then activated, and the stirring motor 901 starts running, driving the stirring rod 902 to rotate. This, in turn, causes the anchor-type stirring blades 903 fixed to the stirring rod 902 to rotate, thoroughly stirring the materials in the reactor body 1 to ensure uniform mixing and promote contact and reaction between reactants. According to the temperature requirements of resin production, a suitable heat transfer medium (heat transfer oil or cooling water) is introduced into the annular external coil 5. Because multiple annular outer coils 5 are arranged vertically at equal intervals, covering most of the outer surface of the vessel body 1, and the connectors 7 of adjacent annular outer coils 5 are connected in series through connecting pipes 8 to form a continuous fluid channel, the heat transfer medium can flow through all annular outer coils 5 in sequence. Simultaneously, a temperature sensor installed on the mounting pipe 14 monitors the temperature inside the vessel body 1 in real time and feeds the data back to the control system. If the temperature is too high, cooling water is introduced to lower it; if the temperature is too low, heat transfer oil is introduced to raise it, ensuring a more uniform temperature across different height areas of the vessel body 1, avoiding localized overheating or undercooling, and providing suitable temperature conditions for the resin reaction. After the resin production material reaction is complete, the control system controls the opening of the discharge bend 11 with an electromagnetic valve on the discharge pipe 10, discharging the reacted resin product from the vessel body 1, achieving automated discharge.

[0029] If it is necessary to clean, inspect, or replace a certain annular outer coil 5, first loosen the screws securing the mounting block 602 corresponding to the annular outer coil 5, remove the mounting block 602, then loosen the bolts between the semi-circular flanges 12 on the two semi-circular coils 501 of the annular outer coil 5, disassemble the two semi-circular coils 501 and remove them for cleaning, inspection, or replacement. For installation, simply reverse the above steps.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
