Description

Technical Field

[0001] This utility model relates to the field of reaction vessels, and in particular to a reaction vessel that facilitates the treatment of residual liquid. Background Technology

[0002] In existing esterification reactions, solid acid catalysts are often used. However, during use, due to the fear of incomplete catalysis, an appropriate amount of fixed acid catalyst (hereinafter referred to as catalyst) is added. This results in some catalyst not being able to dissolve, leaving some catalyst remaining after catalysis. If the catalyst is not cleaned in time, it will block the outlet of the reaction vessel. Furthermore, when new chemical liquids are added next time, a chemical reaction may occur, potentially leading to a safety accident. Utility Model Content

[0003] The purpose of this invention is to provide a reaction vessel that facilitates the handling of residual liquid, ensuring that the catalyst does not remain in the reaction vessel and preventing blockages or safety accidents.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a reaction vessel for convenient handling of residual liquid, comprising a vessel body, a vessel lid, and a metal frame for fixing the vessel body, wherein the vessel lid is provided with a feed inlet, and the vessel body is provided with a discharge outlet.

[0005] The bottom surface of the vessel body has an inverted arc shape, and a row of outlets is opened in the middle of the bottom surface, with a discharge cover provided at the outlet.

[0006] Furthermore, a drive motor is provided on the lid of the vessel, and the output shaft of the drive motor is fixedly connected to a stirring shaft. The stirring shaft extends into the vessel body, and stirring blades are provided on the stirring shaft extending into the vessel body.

[0007] Furthermore, a scraping mechanism is connected to the stirring shaft.

[0008] Furthermore, the scraping mechanism includes a mounting frame, one end of which is fixedly mounted on the stirring shaft. A telescopic spring is installed inside the mounting frame, and a first telescopic rod is installed inside each telescopic spring. One end of the first telescopic rod is fixedly disposed within the mounting frame, and the other end is fixedly connected to a connecting part. The mounting frame has an opening for the telescopic extension of the connecting part. Slider blocks are provided on both sides of the connecting part. Simultaneously, slide rails are installed on both sides inside the mounting frame, allowing the sliders to slide within the slide rails. A scraping part is fixedly connected to the end of the connecting part away from the first telescopic rod, and the scraping part abuts against the side wall of the vessel body.

[0009] Furthermore, an observation window is provided on the vessel body.

[0010] Furthermore, the observation window includes an observation connection box, which is fixedly installed on one side of the vessel body by bolts. Glass is installed on the side of the observation connection box away from the vessel body. A threaded hole is opened at the top of the observation connection box, and a threaded rod is threaded through the threaded hole. A handle is installed at the outer end of the threaded rod in the observation connection box, and a scraper is installed at the inner end of the threaded rod in the observation connection box. A second telescopic rod is provided between the scraper and the observation connection box.

[0011] The present invention provides a reaction vessel for convenient handling of residual liquid, the advantages of which are:

[0012] 1. In this application, after the catalytic reaction is completed, since the bottom surface of the vessel is set as an arc-shaped structure, the catalyst residue will flow along the arc-shaped structure to the middle, thereby preventing the catalyst from remaining in the vessel.

[0013] 2. In this application, by setting a scraping mechanism, the stirring shaft will drive the mounting frame to rotate during rotation, which in turn will drive the connecting part and the scraping part to rotate. During the rotation of the scraping part, the residue attached to the inner wall of the vessel will be scraped to prevent the residue from sticking to the inner wall of the vessel and causing problems. In addition, the connecting part will slide on the slide rails on both sides of the mounting frame as the telescopic spring extends and retracts, thereby driving the scraping part to fit tightly against the inner wall of the vessel, which can improve the cleanliness of the scraping. This makes it easy for the device to scrape the residue attached to the inner wall of the vessel.

[0014] 3. In this application, an observation window is provided. When the end of the glass facing the vessel body is covered with internal mixture or residue, turning the handle will cause the threaded rod to rotate, which in turn will cause the threaded rod to move up and down relative to the observation connection box. This will cause the scraper to move up and down. During the movement, one end of the scraper will scrape away the residue attached to the glass end to prevent the material from affecting the observation effect. In addition, during the up and down movement of the scraper, the second telescopic rod will limit the scraper, making it easy to observe the mixing state inside the main body.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Please see Figure 1-5This utility model provides an embodiment of a reaction vessel for convenient residual liquid treatment, comprising a vessel body 1, a vessel cover 2, and a metal frame 5 for fixing the vessel body 1. The vessel body 1 and the vessel cover 2 are fixedly connected together by bolts. The metal frame 5 is located below the vessel body 1 and is also bolted to it. The metal frame 5 includes a retaining ring and multiple support legs below the retaining ring, making the vessel body 1 more stable. The vessel cover 2 has a feed inlet 3, and the vessel body 1 has a discharge outlet 4 located on the side surface of the vessel body 1. Both the feed inlet 3 and the discharge outlet 4 are connected to pipelines (not shown in the figure) for feeding and discharging.

[0025] Meanwhile, in this embodiment, the bottom surface of the vessel body 1 has an inverted arc shape. Specifically, the bottom surface of the vessel body 1 is closer to the ground from the edge to the center, and an outlet 11 is opened in the middle of the bottom surface. A discharge pipe 7 is provided at the outlet 11, and a discharge cover 8 is connected to the discharge pipe 7. The side of the discharge pipe 7 away from the outlet 11 is provided with external threads, and the discharge cover 8 is provided with internal threads. The discharge pipe 7 and the discharge cover 8 are threaded together. Since the vessel body 1 is supported by the metal frame 5, the vessel body 1 does not contact the ground, so it will not affect the discharge of material from the outlet 11.

[0026] A drive motor 6 is mounted on the vessel lid 2. The output shaft of the drive motor 6 is fixedly connected to a stirring shaft 9, which extends into the vessel body 1. Multiple stirring blades 10 are mounted on the stirring shaft 9 within the vessel body 1. A shaft seal is provided on the vessel lid 2 at the connection between the stirring shaft 9 and the vessel lid 2 to ensure a tight seal. In use, the rotation of the drive motor 6 drives the rotation of the stirring shaft 9, which in turn drives the rotation of the stirring blades 10, thereby accelerating the catalytic dissolution process.

[0027] In this embodiment, a scraping mechanism 12 is connected to the stirring shaft 9. One end of the scraping mechanism 12 is fixedly connected to the stirring shaft 9, and the other end abuts against the side wall of the vessel body 1, thereby cleaning the catalyst residue on the side wall of the vessel body 1 and preventing the formation of catalyst residue.

[0028] Specifically, the scraping mechanism 12 includes a mounting frame 13, which includes multiple mounting frames 13. One end of the mounting frame 13 is fixedly mounted on the stirring shaft 9, and the mounting frames 13 are mounted on both sides of the stirring shaft 9. The mounting frames 13 and the stirring blades 10 are staggered, and the mounting frames 13 and the stirring shaft 9 can be fixed by welding, integral molding, or bolt fixing.

[0029] Each mounting frame 13 is internally equipped with a telescopic spring 14, and each telescopic spring 14 is internally equipped with a first telescopic rod 15. One end of the first telescopic rod 15 is fixedly disposed inside the mounting frame 13, and the other end is fixedly connected to one end of a connecting part 18. The mounting frame 13 has an opening for the telescopic extension of the connecting part 18. Slider blocks 17 are disposed on both sides of the connecting part 18. At the same time, slide rails 16 are installed on both sides inside the mounting frame 13, and the sliders 17 can slide within the slide rails 16. Meanwhile, a scraping part 19 is fixedly connected to the end of the connecting part 18 away from the first telescopic rod 15. The scraping part 19 abuts against the side wall of the vessel body 1. In this embodiment, two connecting parts 18 are connected to one scraping part 19, thereby improving the connection strength of the scraping part 19.

[0030] Meanwhile, in order to facilitate observation of the state inside the vessel body 1, an observation window 20 is provided on the vessel body 1.

[0031] Specifically, the observation window 20 includes an observation connection box 21, which is fixedly mounted to one side of the vessel body 1 by bolts.

[0032] A glass 25 is installed on the side of the observation connection box 21 away from the vessel body 1. A threaded hole is opened at the top of the observation connection box 21. A threaded rod 22 is threaded through and connected to the threaded hole. A handle 23 is installed at the end of the threaded rod 22 located at the outer end of the observation connection box 21. A scraper 26 is installed at the end of the threaded rod 22 located at the inner side of the observation connection box 21. A second telescopic rod 24 is provided between the scraper 26 and the observation connection box 21. At the same time, one end of the scraper 26 abuts against the glass 25.

[0033] In practical use, after the catalytic reaction is completed, since the bottom surface of the vessel 1 is set as an arc-shaped structure, the catalyst residue will flow along the arc-shaped structure to the middle and then be discharged from the outlet, thereby preventing the catalyst from remaining in the vessel 1.

[0034] Regarding the residue remaining on the side wall of the vessel body 1, this application employs a scraping mechanism 12. During the rotation of the stirring shaft 9, the mounting frame 13 rotates, which in turn rotates the connecting part 18 and the scraping part 19. As the scraping part 19 rotates, it scrapes the residue adhering to the inner wall of the vessel body 1, preventing the residue from sticking to the inner wall of the vessel body 1 and causing problems. Furthermore, the connecting part 18 extends and retracts with the extension and retraction of the telescopic spring 14, and slides the slider 17 on the slide rails 16 on both sides inside the mounting frame 13. This causes the scraping part 19 to fit tightly against the inner wall of the vessel body 1, thereby improving the cleanliness of the scraping. This device facilitates the scraping of residue adhering to the inner wall of the vessel body 1.

[0035] Meanwhile, due to long-term use, dirt accumulates inside the glass 25 in the observation window 20. Since cleaning is inconvenient inside the vessel body 1, this application provides an observation window 20. When the end of the glass 25 facing the vessel body 1 is covered with internal mixture or residue, turning the handle 23 will rotate the threaded rod 22, which in turn moves the threaded rod 22 up and down relative to the observation connection box 21. This moves the scraper 26 up and down. During the movement, one end of the scraper 26 will scrape away the residue attached to the end of the glass 25, preventing the material from affecting the observation effect. Furthermore, during the up and down movement of the scraper 26, the second telescopic rod 24 will limit the scraper 26, making it convenient to observe the mixing state inside the main body.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

The units described as separate components may or may not be physically separate, and the components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs. Those skilled in the art can understand and implement this without any creative effort.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
