Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to an aqueous epoxy resin reaction vessel. Background Technology

[0002] Epoxy resin is an excellent industrial material, typically produced through a polycondensation reaction of epoxy compounds and active hydrogen compounds. It can be used in various fields, such as coatings, adhesives, molds, and composite materials. In the production process of epoxy resin, it is usually necessary to use an epoxy resin reactor to stir and mix various epoxy resin raw materials at a suitable temperature.

[0003] In the process of preparing epoxy resin, the inner wall of the reactor needs to be heated to transfer heat to the epoxy resin raw materials. Stirring allows the materials to be quickly mixed, enabling rapid production of epoxy resin. However, epoxy resin is viscous and easily adheres to the inner wall of the reactor. During the heating process, the epoxy resin adhering to the inner wall may be scorched, which has certain drawbacks. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an aqueous epoxy resin reactor with advantages such as edge scraping and stirring, and leakage prevention, thus solving the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: an aqueous epoxy resin reactor, comprising a shell, the shell including a top cover, the top cover being located above the shell, the bottom of the shell having uniformly fixed support feet in a ring shape, a feed cylinder fixedly installed on one side of the top of the top cover, a discharge cylinder fixedly connected to the bottom of the shell, a support frame fixedly installed on the top of the top cover, a motor fixedly installed on the top of the support frame, an inner ring provided on the inner top wall of the top cover, an annular groove formed on the outer ring of the inner ring, a magnetic head fixedly connected to the end of the output shaft of the motor, the magnetic head being located in the inner ring of the inner ring, a rotating shaft rotatably sleeved on the outer ring of the inner ring, a protruding ring provided on the top inner ring of the rotating shaft, the protruding ring being located inside the annular groove.

[0006] Made from the above materials, stirring rod A and stirring rod B uniformly mix the materials inside the shell. The inclined surfaces of stirring rod A and stirring rod B separate the materials into different layers. The arc scraper removes the materials adhering to the inner wall of the shell. The arc surface of the arc scraper conveys the materials to the center of the shell, so that the materials can be mixed evenly.

[0007] Preferably, the top of the rotating shaft is provided with a collar, which is made of magnetic material. The collar is located on the outer ring of the inner ring, the convex ring is adapted to the shape of the ring groove, and the collar and the magnetic head are attracted by opposite magnetic forces.

[0008] Made of the above materials, when the magnetic head rotates, it can drive the collar to rotate together. Since the inner ring seals the inside of the outer shell, it prevents the resin material from leaking through the joint during the mixing process, thus achieving stirring of the material during the sealing process.

[0009] Preferably, the outer ring of the rotating shaft is uniformly fixed with stirring rods A. The cross-section of stirring rod A is triangular. An arc scraper is fixedly connected between the ends of stirring rod A. One side of the arc scraper is arc-shaped. The outer ring of the arc scraper fits into the inner ring of the outer shell.

[0010] Made of the above materials, when the motor drives the magnetic head to rotate through the output shaft, the magnetic forces between the magnetic head and the collar are attracted by opposite polarities, which simultaneously drives the collar located on the outer ring of the inner ring to rotate synchronously, and the rotating shaft rotates together with the collar.

[0011] Preferably, the outer ring of the rotating shaft is uniformly and fixedly installed with the stirring rod B in a ring at the bottom of the stirring rod A, and a scraper head is fixedly installed at the end of the stirring rod B. One side of the scraper head is in contact with the inner wall of the outer shell, and one side of the scraper head is an arc surface.

[0012] Made of the above materials, during the rotation of the stirring rod B driven by the rotating shaft, the scraper head will scrape off the material adhering to the inner wall of the outer shell and convey it to the inner center of the outer shell through the arc surface of the scraper head, so that the material can be evenly mixed between the inner and outer rings while being stirred.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This water-based epoxy resin reactor uses a structure including a magnetic head, a rotating shaft, and an arc scraper to scrape off materials adhering to the inner wall of the outer shell. When the motor is started, the output shaft drives the magnetic head to rotate. As the magnetic head rotates, the magnetic force attracts the opposing forces between the magnetic head and the inner ring, causing the rotating shaft to rotate along with it. The arc scraper removes the material adhering to the inner wall of the outer shell. The arc surface of the scraper conveys the material towards the center of the outer shell, ensuring uniform mixing and preventing the material adhering to the inner wall from scorching during heating. This achieves a cyclical scraping effect.

[0015] 2. This water-based epoxy resin reactor achieves a sealed reaction by setting up structures such as an inner ring, ring groove, collar ring, and convex ring. The collar ring and the magnetic head are attracted by opposite magnetic properties. When the magnetic head rotates, it can drive the collar ring to rotate together. Since the inner ring seals the inside of the outer shell, it prevents the resin material from leaking through the connection during the mixing process, and achieves the effect of stirring the material during the sealing process.

[0021] 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.

[0022] Please see Figures 1-3 A water-based epoxy resin reactor includes an outer shell 1, which includes a top cover 11 located above the outer shell 1. Support legs 12 are uniformly and annularly fixedly installed at the bottom of the outer shell 1. A feed cylinder 13 is fixedly installed on one side of the top of the top cover 11. A discharge cylinder 14 is fixedly connected to the bottom of the outer shell 1. A support frame 15 is fixedly installed on the top of the top cover 11, and a motor 2 is fixedly installed on the top of the support frame 15. An inner ring is provided on the inner top wall of the top cover 11, and an annular groove 16 is formed on the outer ring of the inner ring. A magnetic head 21 is fixedly connected to the end of the output shaft of the motor 2. The magnetic head 21 is located within the inner ring. A rotating shaft 3 is rotatably sleeved on the outer ring of the inner ring. A protruding ring 31 is provided on the top inner ring of the rotating shaft 3, and the protruding ring 31 is located inside the annular groove 16.

[0023] Please see Figures 1-4 The top of the rotating shaft 3 is provided with a collar, which is made of magnetic material. The collar is located on the outer ring of the inner ring. The convex ring 31 is adapted to the shape of the ring groove 16. The collar and the magnetic head 21 are attracted by opposite magnetic properties. When the magnetic head 21 rotates, it can drive the collar to rotate together. Since the inner ring seals the inside of the outer shell 1, it prevents the resin material from leaking through the connection during the mixing process, and realizes the stirring of the material during the sealing process.

[0024] Please see Figures 1-4The outer ring of the rotating shaft 3 is uniformly fixed with stirring rods A32. The cross-section of stirring rod A32 is triangular. When stirring rod A32 rotates, the material located on the inclined surface of stirring rod A32 is lifted upward by the rotational force, so that the material can be uniformly stirred inside the outer shell 1. The ends of stirring rod A32 are fixedly connected with arc scraper 33. One side of arc scraper 33 is arc surface. The outer ring of arc scraper 33 is in contact with the inner ring of outer shell 1. Through the connection of the inner ring, when motor 2 drives magnetic head 21 to rotate through output shaft, the magnetic forces between magnetic head 21 and collar are opposite and attract each other, and at the same time drive collar located on the outer ring of inner ring to rotate synchronously. The rotating shaft 3 rotates together with collar.

[0025] When the rotating shaft 3 rotates, it drives the stirring rod A32 to stir the resin material inside the outer shell 1, so that the materials are evenly mixed. As the inner wall of the top cover 11 is heated, the rapid fusion of the resin materials is accelerated. However, the materials sticking to the inner wall of the outer shell 1 may be heated and burned. At this time, when the rotating shaft 3 drives the arc scraper 33 to rotate, it will scrape off the materials sticking to the inner wall of the outer shell 1. The materials move from the inner wall of the outer shell 1 to the center through the arc surface of the arc scraper 33, so that the materials are evenly mixed while avoiding the materials from sticking to the inner wall of the outer shell 1 and burning.

[0026] Please see Figures 1-4 The outer ring of the rotating shaft 3 is located at the bottom of the stirring rod A32 and the stirring rod B34 is uniformly fixedly installed in a ring. The end of the stirring rod B34 is fixedly installed with a scraper head 35. One side of the scraper head 35 is in contact with the inner wall of the outer shell 1. One side of the scraper head 35 is an arc surface. During the rotation of the stirring rod B34 driven by the rotating shaft 3, the scraper head 35 will scrape off the material adhering to the inner wall of the outer shell 1 and convey it to the middle of the inner part of the outer shell 1 through the arc surface of the scraper head 35, so that the material can be evenly mixed between the inner and outer rings while being stirred.

[0027] Working principle: Open the feed cylinder 13 and pour the materials to be mixed into the interior of the outer shell 1. Then start the motor 2, which drives the magnetic head 21 to rotate via the output shaft. When the magnetic head 21 rotates, due to the attraction between the magnetic force and the collar, it drives the rotating shaft 3 to rotate together through the inner ring, preventing material leakage through the connection seam between the output shaft and the top cover 11 during mixing. The rotating shaft 3 simultaneously drives the stirring rod A32 and the arc scraper 33, and the stirring rod B34 and the scraper head 35 to rotate together. The stirring rod A32 and the stirring rod B34 respectively uniformly mix the materials inside the outer shell 1. 2. The inclined surface of the stirring rod B34 separates the material into different layers. The arc scraper 33 scrapes off the material adhering to the inner wall of the outer shell 1. Through the arc surface of the arc scraper 33, the material is conveyed to the center of the inner shell 1, so that the material can be mixed evenly. After the mixing is completed, the discharge cylinder 14 is opened to discharge the material. As the material accumulates, some of it will stick to the bottom inner ring of the outer shell 1 and cannot be discharged. At this time, the rotating shaft 3 drives the scraper head 35 to rotate, scraping off the material located on the inner wall. Through the arc surface of the scraper head 35, the material on the inner wall is conveyed to the center, which facilitates the conveying and even mixing.
