Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically a reaction vessel for the production of methacrylate. Background Technology

[0002] Methacrylates are an important class of organic chemical raw materials, widely used in coatings, adhesives, plastics and many other fields. The reaction vessel is a key piece of equipment for the synthesis of methacrylates. The reaction vessel provides a closed and stable space for the synthesis reaction of methacrylates, ensuring that the reaction can be carried out under specific environmental conditions. By heating, cooling and stirring the methacrylates in the reaction vessel, the methacrylates material is made to react under specific conditions, thereby achieving the expected production purpose.

[0003] Patent document CN208554184U discloses a high-efficiency reaction vessel for acetic acid-propylene emulsion, comprising a vessel body, a vessel cover, and a stirring device. The vessel cover has a feed inlet, and the bottom of the vessel body has a discharge outlet. The stirring device includes a planetary gear set and a drive device for driving the planetary gear set. The planetary gear set includes a sun gear and several planetary gears. A main stirring blade extending into the vessel body is connected to the sun gear, and auxiliary stirring blades extending into the vessel body are connected to the planetary gears. The main stirring blade includes a main stirring shaft and a first blade mounted on the main stirring shaft. The auxiliary stirring blade includes a secondary stirring shaft and a second blade mounted on the secondary stirring shaft, and the secondary stirring shaft is shorter than the main stirring shaft. This invention provides a method for achieving high efficiency in the reaction vessel. The aforementioned publication describes a high-efficiency methacrylate emulsion reactor, which primarily focuses on providing good stirring at a higher position within the reactor and preventing the reaction from being affected by synchronous rotation. However, it fails to consider that the viscous nature of methacrylate causes some residue to splash onto the upper inner wall during the stirring reaction. Over time, this residue can detach and enter the reaction mixture during subsequent production, leading to decreased product purity, excessive impurities, and compromised quality. Therefore, it is necessary to develop a methacrylate production reactor to ensure product quality. Utility Model Content

[0004] The purpose of this invention is to provide a reaction vessel for the production of methacrylates, so as to solve the technical problem mentioned in the background art where reactants adhering to the inner wall fall into the material, resulting in a decrease in quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reaction vessel for the production of methacrylate, comprising a tank body and a sealing cover, wherein a motor is fixedly installed on the sealing cover, and a rotating frame is fixedly connected to the output end of the motor, with one end of the rotating frame passing through the interior of the tank body; a first sealing box is fixedly connected to the rotating frame; a first electric push rod is fixedly installed inside the first sealing box, with one end of the first electric push rod passing through the interior of the first sealing box; a second sealing box is fixedly connected to one end of the first electric push rod; a second electric push rod is fixedly installed inside the second sealing box, with one end of the second electric push rod passing through the interior of the second sealing box; and a scraper is fixedly connected to one end of the second electric push rod.

[0006] Preferably, one end of the first sealing box is provided with a hole, and the first electric push rod passes through the hole and exits the interior of the first sealing box. A sealing ring is provided on the inner side of the hole, and one end of the first electric push rod passes through the interior of the sealing ring. The second sealing box is also provided with a hole and a sealing ring.

[0007] Preferably, a support frame is fixedly installed on the outer wall of the tank, and multiple support legs are fixedly installed on the lower side of the support frame. A spring is fixedly connected to the bottom end of each support leg, and a base is fixedly installed on the other end of the spring. One end of the support leg passes through the base, and the base is in contact with the ground.

[0008] According to the claim, a reaction vessel for the production of methacrylate is characterized in that: a damper is installed inside the base, and one end of the damper passes through the interior of the spring and is fixedly connected to the support leg.

[0009] Preferably, the sealing cover has an inlet at the top, an outlet at the bottom, and a pressure device at the top.

[0010] Preferably, a stirring rod is fixedly installed at the bottom end of the rotating frame, and multiple stirring rods are provided.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. This utility model maintains the purity of the tank by installing a scraper. The motor above the tank is energized to rotate the rotating frame inside the tank, which stirs the added materials evenly and enhances the mixing degree. While rotating, the first electric push rod is activated by the wireless remote control to extend and retract, pushing the second sealing box so that the scraper can touch the inner wall of the tank to clean the inner wall. Then, the second electric push rod in the second sealing box pushes the scraper to move up and down, increasing the cleaning area of ​​the scraper and cleaning the upper wall of the reactor in time. This prevents the accumulation of unevenly stirred reactants on the upper wall of the reactor and ensures the quality of the product.

[0013] 2. This utility model maintains the stability of the tank by installing spring dampers. Multiple support frames set under the tank can better support the tank, and each support leg is equipped with a base. A combination of spring and damper is installed in the base. When the tank shakes violently during operation, the spring absorbs the external impact force, and the damper gradually dissipates this energy, thereby reducing vibration and buffering impact. The violent impact during the reaction in the reactor will cause continuous wear on the inner wall. These vibration damping devices can effectively reduce the wear on the inner wall of the reactor, thereby effectively increasing the service life of the reactor. Attached Figure Description

[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] Please see Figure 1 - Figure 4A reaction vessel for producing methacrylate includes a tank body 1 and a sealing cover 2. A motor 3 is fixedly mounted on the sealing cover 2. A rotating frame 10 is fixedly connected to the output end of the motor 3, and one end of the rotating frame 10 passes through the interior of the tank body 1. A stirring rod 11 is fixedly mounted at the bottom end of the rotating frame 10, and multiple stirring rods 11 are provided. A first sealing box 12 is fixedly connected to the rotating frame 10. An electric push rod 13 is fixedly mounted inside the first sealing box 12, and one end of the first electric push rod 13 passes through the sealing cover. Inside box 12, one end of electric push rod 13 is fixedly connected to sealed box 2 14. Electric push rod 15 is fixedly installed inside sealed box 2 14, with one end of electric push rod 15 extending through the interior of sealed box 2 14. A scraper 16 is fixedly connected to one end of electric push rod 15. During the production reaction of methacrylate in the reactor, the raw material is first placed into tank 1 through inlet 6. Then, the rotating frame 10 is rotated by energizing motor 3. The stirring rod 11 on the rotating frame 10 can... The raw materials are thoroughly mixed to ensure a proper reaction. The final product is discharged through outlet 7. Due to the viscosity of methacrylate, some of it splashes onto the inner wall during the reaction, leaving residue. Over time, this residue can detach and enter the reaction mixture during subsequent production, leading to decreased product purity, excessive impurities, and quality issues. The motor 3 above tank 1 powers the rotating frame 10 inside tank 1 to stir the added materials evenly, enhancing the mixing degree. Simultaneously, a wireless remote control activates the first electric push rod 13 to extend and retract, pushing the second sealing box 14 so that the scraper 16 can contact the inner wall of tank 1 for cleaning. Then, the second electric push rod 15 inside the second sealing box 14 pushes the scraper 16 up and down, increasing its cleaning area and promptly cleaning the upper wall of the reactor. This prevents unmixed reactants from accumulating on the upper wall of the reactor, ensuring product quality.

[0021] Please see Figure 2 and Figure 3 One end of the sealing box 12 has a hole 17, and the first electric push rod 13 passes through the hole 17 and exits the interior of the sealing box 12. A sealing ring 18 is provided inside the hole 17, and one end of the first electric push rod 13 passes through the interior of the sealing ring 18. The sealing box 2 14 also has a hole 17 and a sealing ring 18. The hole 17 and the silicone sealing ring 18 provided in the sealing box 12 are to prevent liquid from seeping into the sealing box 12 and causing the telescopic rod to malfunction.

[0022] Please see Figure 1 and Figure 4A support frame 4 is fixedly installed on the outer wall of the tank body 1. Multiple support legs 8 are fixedly installed on the lower side of the support frame 4. A spring 20 is fixedly connected to the bottom end of each support leg 8. A base 9 is fixedly installed on the other end of the spring 20, and one end of the support leg 8 passes through the base 9. The base 9 is in contact with the ground. A damper 19 is installed inside the base 9, and one end of the damper 19 passes through the interior of the spring 20 and is fixedly connected to the support leg 8. To maintain the stability of the tank body 1, the installation of the spring 20 and damper 19 maintains the stability of the tank body 1. Multiple support legs 8 are installed on the support frame 4 below the tank body 1. The support frame 4 provides better support for the tank 1, and each support leg 8 is equipped with a base 9. A spring 20 and a damper 19 are installed in the base 9. When the tank 1 shakes violently during operation, the spring 20 absorbs the external impact force, and the damper 19 gradually dissipates this energy, thereby reducing vibration and buffering impact. The violent impact during the reaction in the reactor will cause continuous wear on the inner wall. These vibration damping devices can effectively reduce the wear on the inner wall of the reactor, thereby effectively increasing the life of the reactor.

[0023] Please see Figure 1 The sealing cover 2 has an inlet 6 on top and an outlet 7 fixedly installed at the bottom. A pressure device 5 is installed on top of the sealing cover 2. The inlet 6 on top of the sealing cover 2 is used to put in raw materials and react them in the tank 1. The outlet 7 below the sealing cover 2 is used to discharge the products after the reaction in the reactor. The pressure device 5 on top of the sealing cover 2 is to prevent the reactor from being too pressurized, which could lead to fire, explosion or other accidents.

[0024] Working principle: The motor 3 above tank 1 is energized to rotate the rotating frame 10 inside tank 1, stirring the added materials evenly and enhancing the mixing degree. Simultaneously, a wireless remote control activates the extension and retraction of electric push rod 13, pushing the sealing box 14 so that scraper 16 can contact the inner wall of tank 1 for cleaning. Then, electric push rod 15 inside sealing box 14 pushes scraper 16 up and down, increasing the cleaning area and promptly cleaning the upper wall of the reactor, preventing unmixed reactants from accumulating on the upper wall of the reactor. To ensure product quality, multiple support frames 4 are installed under the support frame 4 of the tank body 1 to provide better support for the tank body 1. Each support leg 8 is equipped with a base 9, and a spring 20 and a damper 19 are installed together in the base 9. When the tank body 1 shakes violently during operation, the spring 20 absorbs the external impact force, and the damper 19 gradually dissipates this energy, thereby reducing vibration and buffering impact. The violent impact during the reaction in the reactor will cause continuous wear on the inner wall. These vibration damping devices can effectively reduce the wear on the inner wall of the reactor, thereby effectively increasing the life of the reactor.
