Description

Technical Field

[0001] This utility model relates to the field of resin production, and then discloses a reaction vessel for resin production. Background Technology

[0002] As the core equipment in resin synthesis, the reactor undertakes key processes such as monomer polymerization, functional group modification, and product purification. Its performance directly determines the molecular weight distribution, viscosity stability, and production efficiency of the resin. Currently, approximately 80 million tons of resin (including epoxy resin, polyurethane, phenolic resin, etc.) are produced annually worldwide using reactors, and are widely used in coatings, adhesives, composite materials, and other fields.

[0003] In existing technologies, the reaction vessel is made by putting resin raw materials into a sealed vessel body, heating it by introducing steam or hot water through the outer jacket, or cooling it by introducing cold water to maintain the temperature required for the reaction. At the same time, the stirring device inside the vessel is driven by a motor to rotate, so that the materials are mixed evenly and the reaction is promoted. Finally, the reaction endpoint is determined by manual sampling and testing, and the resin synthesis is completed.

[0004] Because the stirring rod is located in the center of the reactor, its stirring range is limited by the length of the rod and the diameter of the blades. The stirring effect cannot reach the edge area, which will result in the raw materials at the edge of the reactor not being fully stirred, thus affecting the resin synthesis efficiency. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a reaction vessel for resin production. By driving the disc to rotate, the second fixed rod rotates synchronously with the disc. At the same time, because the first toothed ring meshes with the toothed blocks on the inner wall of the toothed ring disc, the first toothed ring drives the second fixed rod to rotate around its own axis, realizing the compound motion of the stirring rod, enhancing the stirring effect, ensuring that the raw materials are mixed evenly, and avoiding the situation where the raw materials at the edges cannot be mixed.

[0006] The objective of this utility model is achieved through the following technical solution: A resin production reactor includes a reactor body, a first fixing rod, and a heating assembly. A sealing cover is provided at the upper end of the reactor body, and the first fixing rod is fixedly connected to the lower end of the sealing cover. A toothed ring disk is fixedly connected to the lower end of the first fixing rod. A disc is rotatably mounted at the lower end of the toothed ring disk, and two second fixing rods are rotatably mounted at the lower end of the disc. The upper ends of the second fixing rods pass through the discs and are fixedly connected to the first toothed ring. The first toothed ring meshes with the toothed blocks on the inner wall of the toothed ring disk. Multiple equidistantly distributed stirring rods are fixedly mounted to the outer wall of the second fixing rods. A heating assembly is provided at the right end of the reactor body.

[0007] In one optional embodiment, the stirring rods on the outer walls of the two second fixed rods are staggered, a connecting rod is fixedly connected to the upper end of the disc, a motor is fixedly connected to the upper end of the sealing cover, and the connecting rod is fixedly connected to the output end of the motor.

[0008] In one optional embodiment, two connecting plates are fixed to the outer wall of the disc, the two connecting plates are symmetrically arranged, an mounting plate is fixed to the outer side of the connecting plates, and a scraper is slidably arranged on the inner wall of the mounting plate.

[0009] In one optional embodiment, the outer wall of the scraper is arc-shaped and fits against the inner wall of the reactor body. The lower end of the reactor body is funnel-shaped and a bottom plate is fixedly connected to the lower end of the reactor body.

[0010] In one optional embodiment, the heating assembly includes a heating cover, the outer wall of the reactor body is fixedly connected to the heating cover, a water tank is fixedly connected to the upper end of the bottom plate, and a water pump is fixedly connected to the upper end of the water tank.

[0011] In one optional embodiment, a first connecting pipe is fixedly connected to the outlet end of the water pump, the other end of the first connecting pipe is disposed inside the heating cover, and a second connecting pipe is fixedly connected to the upper end of the water tank.

[0012] In one optional embodiment, the end of the second connecting pipe away from the water tank is located inside the heating cover, the second connecting pipe is located above the first connecting pipe, and a heating pipe is fixed to the inner wall of the water tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By driving the disc to rotate, the second fixed rod rotates synchronously with the disc. At the same time, because the first toothed ring meshes with the toothed blocks on the inner wall of the toothed ring disc, the first toothed ring drives the second fixed rod to rotate around its own axis, realizing the compound motion of the stirring rod, enhancing the stirring effect, ensuring that the raw materials are mixed evenly, and avoiding the situation where the raw materials at the edges cannot be mixed.

[0014] The staggered distribution of the stirring rods reduces dead zones in the mixing process, further improving the uniformity of material mixing. The connecting plate and mounting plate fix the position of the scraper. As the disc rotates, the scraper can scrape off the material adhering to the inner wall of the reactor body, preventing the material from sticking to the wall and affecting the reaction efficiency and product purity. The funnel-shaped lower end face facilitates the discharge of material after the reaction is completed. Attached Figure Description

[0021] Please refer to Figures 1-5 This utility model provides an embodiment of a resin production reactor, including a reactor body 1; it also includes a first fixing rod 101 and a heating assembly; a sealing cover 2 is provided at the upper end of the reactor body 1, and the first fixing rod 101 is fixedly connected to the lower end of the sealing cover 2. A toothed ring disk 102 is fixedly connected to the lower end of the first fixing rod 101. A disc 103 is rotatably provided at the lower end of the toothed ring disk 102. Two second fixing rods 104 are rotatably provided at the lower end of the disc 103. The upper end of the second fixing rod 104 passes through the disc 103 and is fixedly connected to a first toothed ring 105. The first toothed ring 105 meshes with the toothed blocks on the inner wall of the toothed ring disk 102. Multiple equally spaced stirring rods 106 are fixed to the outer wall of rod 104. A heating assembly is provided at the right end of the reactor body 1. By driving the disc 103 to rotate, the second fixed rod 104 rotates synchronously with the disc 103. At the same time, because the first toothed ring 105 meshes with the toothed block on the inner wall of the toothed ring disc 102, the first toothed ring 105 drives the second fixed rod 104 to rotate around its own axis, so that the stirring rod 106 can fully stir the raw materials and ensure that the raw materials are mixed evenly. This solves the problem that the stirring range is limited by the length of the rod and cannot reach the edge area, which would cause the raw materials at the edge of the reactor to not be fully stirred, thus affecting the resin synthesis efficiency.

[0022] Please refer to Figures 1-4In a preferred embodiment of this utility model, the stirring rods 106 on the outer walls of the two second fixed rods 104 are staggered. A connecting rod 3 is fixedly connected to the upper end of the disc 103, and a motor 4 is fixedly connected to the upper end of the sealing cover 2. The connecting rod 3 is fixedly connected to the output end of the motor 4. Two connecting plates 5 are fixedly connected to the outer wall of the disc 103. The two connecting plates 5 are symmetrically arranged. An mounting plate 6 is fixedly connected to the outer side of the connecting plate 5. A scraper 7 is slidably arranged on the inner wall of the mounting plate 6. The outer wall surface of the scraper 7 is arc-shaped and is flush with the outer wall surface of the reaction vessel. The inner walls of the reactor body 1 are in close contact with each other. The lower end of the reactor body 1 is funnel-shaped. A bottom plate 8 is fixed to the lower end of the reactor body 1. The staggered distribution of the stirring rods 106 can reduce the dead corners of the stirring and further improve the uniformity of material mixing. The connecting plate 5 and the mounting plate 6 fix the position of the scraper 7. The scraper 7 rotates with the disc 103 and can scrape off the material adhering to the inner wall of the reactor body 1, so as to avoid the material adhering to the wall and affecting the reaction efficiency and product purity. The funnel-shaped lower end facilitates the discharge of material after the reaction is completed and reduces residue.

[0023] Please refer to Figure 1 and Figure 5 In a preferred embodiment of this utility model, the heating assembly includes a heating cover 201. The heating cover 201 is fixedly connected to the outer wall of the reactor body 1. A water tank 202 is fixedly connected to the upper end of the bottom plate 8. A water pump 203 is fixedly connected to the upper end of the water tank 202. A first connecting pipe 204 is fixedly connected to the outlet end of the water pump 203. The other end of the first connecting pipe 204 is located inside the heating cover 201. A second connecting pipe 205 is fixedly connected to the upper end of the water tank 202. The end of the second connecting pipe 205 away from the water tank 202 is located inside the heating cover 201. The second connecting pipe 205 is located above the first connecting pipe 204. The inner wall of the water tank 202... A heating pipe 206 is fixedly connected to the reactor body 1, and a heating cover 201 surrounds the reactor body 1 to make the heat distribution more uniform and improve the heating efficiency. A water tank 202 stores the medium used for heating, and a water pump 203 provides power for the circulation of the medium to realize the heat transfer. The second connecting pipe 205 is located above the first connecting pipe 204, which is conducive to the full circulation of the medium in the heating cover 201 and improves the heat exchange efficiency. The heating pipe 206 heats the medium in the water tank 202 to provide a stable heat source for the reaction. The heat is transferred to the reactor body 1 through the circulation of the medium to realize the indirect heating of the material and avoid local overheating.

[0024] In use, the resin raw material is first added into the reactor body 1, and the sealing cover 2 is put on to ensure the reaction space is sealed. The motor 4 is started, and the motor 4 drives the disc 103 to rotate through the connecting rod 3. When the disc 103 rotates, the second fixed rod 104 revolves with the disc 103. At the same time, because the first toothed ring 105 meshes with the toothed block on the inner wall of the toothed ring disc 102, the second fixed rod 104 rotates around its own axis, so that the stirring rod 106 can fully stir the raw material and ensure that the raw material is mixed evenly. At this time, the water inside the water tank 202 is heated by activating the heating pipe 206. The water pump 203 delivers the hot water to the heating cover 201 through the first connecting pipe 204. The heating cover 201 surrounds the reactor body 1 and evenly transfers heat to the internal raw materials to maintain the temperature required for the reaction. By continuously delivering hot water, the water level in the heating cover 201 rises and flows back to the water tank 202 through the second connecting pipe 205 above, forming a circulation to ensure uniform and efficient heating. During the stirring process, the disc 103 drives the connecting plate 5 to rotate synchronously, so that the scraper 7 rotates against the inner wall of the reactor body 1 to scrape off the raw materials remaining on the inner wall of the reactor body 1, so as to avoid the raw materials adhering and affecting the reaction or causing waste.

[0025] Through the above steps, by driving the disc 103 to rotate, the second fixed rod 104 rotates synchronously with the disc 103. At the same time, because the first toothed ring 105 meshes with the toothed block on the inner wall of the toothed ring disc 102, the first toothed ring 105 drives the second fixed rod 104 to rotate around its own axis, so that the stirring rod 106 can fully stir the raw materials and ensure that the raw materials are mixed evenly. This solves the problem that the stirring range is limited by the length of the rod and cannot reach the edge area, which would cause the raw materials at the edge of the reactor to not be fully stirred, thus affecting the resin synthesis efficiency.

[0026] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations (e.g., variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.) will be conceived by those skilled in the art without actually departing from the scope and spirit of the claims.

[0027] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
