Description

Technical Field

[0001] This utility model relates to a stirred dispersion reaction vessel. Background Technology

[0002] Currently, stirred dispersion vessels are specialized reaction vessels used to achieve material stirring and uniform dispersion. For example, Chinese patent CN216458558U discloses a stirred dispersion vessel. In such vessels, a motor drives a stirring paddle to rotate, thereby stirring the materials. Existing technology typically includes a scraper on the stirring paddle, which rotates with the paddle to remove material adhering to the vessel's inner wall. This prevents a large amount of material adhering to the inner wall, which could affect heat transfer and thus the reaction quality. However, this type of stirred dispersion vessel cannot accommodate a temperature sensing tube at the lower end of the vessel because the tube would collide and interfere with the rotating paddle. The inability to install a temperature sensing tube also prevents the placement of a thermometer at the lower end of the vessel, thus making it impossible to measure the reaction temperature at the bottom of the vessel. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a stirred dispersion reaction vessel that can install a temperature measuring tube at the lower end of the vessel body and avoid collision and interference between the temperature measuring tube and the stirring paddle. Furthermore, a thermometer can be installed in the temperature measuring tube to measure the reaction temperature at the bottom of the vessel body.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a stirring and dispersing reactor, including a reactor body, a temperature measuring tube, a stirring paddle and multiple scrapers, wherein the stirring paddle includes a central shaft, a first lower slurry, a second lower slurry, a first upper slurry and a second upper slurry;

[0005] The temperature measuring tube is connected to the lower end of the vessel body and extends into the interior of the vessel body;

[0006] The central shaft is rotatably connected to the vessel body and extends into the interior of the vessel body;

[0007] The first lower slurry, the second lower slurry, the first upper slurry, and the second upper slurry are all located inside the vessel body;

[0008] The first and second lower slurry bodies are respectively connected to the lower end of the central shaft;

[0009] The first upper slurry is connected to the central shaft and located above the first lower slurry;

[0010] The second upper slurry is connected to the central shaft and located above the second lower slurry;

[0011] A first gap is provided between the first lower slurry and the first upper slurry to avoid the temperature measuring tube, and a second gap is provided between the second lower slurry and the second upper slurry to avoid the temperature measuring tube. Both the first gap and the second gap are located at the same height as the temperature measuring tube.

[0012] The first lower slurry, the second lower slurry, the first upper slurry, and the second upper slurry are each connected to a scraper. The scraper connected to the first lower slurry and the scraper connected to the second lower slurry both abut against the inner bottom wall of the vessel, and the scraper connected to the first upper slurry and the scraper connected to the second upper slurry both abut against the inner side wall of the vessel.

[0013] Furthermore, the first and second lower slurry bodies are at the same height and are 180° apart in the circumferential direction. The first and second upper slurry bodies are at the same height and are 180° apart in the circumferential direction.

[0014] To further improve the efficiency of stirring and dispersing, a plurality of lower blades are connected to the central shaft and are arranged circumferentially at intervals. The lower blades are located above the first lower slurry and the second lower slurry and below the first upper slurry and the second upper slurry.

[0015] To further improve the efficiency of stirring and dispersing, a plurality of upper blades are connected to the central shaft and are arranged in a circumferentially spaced manner. The upper blades are located above the first upper slurry and the second upper slurry.

[0016] Furthermore, a first connecting rod is connected between the first upper slurry and the first lower slurry, and / or a second connecting rod is connected between the second upper slurry and the second lower slurry.

[0017] Furthermore, the stirred dispersion reactor also includes a mounting base, a scraping component, a reset elastic element, a limiting mechanism, and protective components;

[0018] The mounting base is connected to the first connecting rod, and the scraping component is rotatably connected to the mounting base and has an initial position and a clearance position during the rotation relative to the mounting base.

[0019] The limiting mechanism is disposed between the mounting base and the scraping component and is used to restrict the scraping component in the initial position from rotating away from the avoidance position, but does not restrict the scraping component in the initial position from rotating toward the avoidance position;

[0020] When the scraping component is in the initial position, one end of the scraping component abuts against the inner wall of the vessel body, so that when the central axis rotates, it drives the first connecting rod, the mounting base and the scraping component to rotate together around the central axis, thereby scraping off the material on the inner wall of the vessel body through the scraping component;

[0021] The protective component is connected to the vessel body and covers the outside of the temperature measuring tube. The scraping component, the protective component, the temperature measuring tube, the first interval, and the second interval are all located at the same height. When the scraping component rotates with the central axis to abut against the protective component, the protective component is used to push the scraping component to rotate from the initial position to the avoidance position.

[0022] The reset elastic element is installed between the scraper component and the mounting base and is used to drive the scraper component to rotate from the avoidance position to the initial position when the scraper component disengages from the protective component.

[0023] A further specific structure of the limiting mechanism is provided, the limiting mechanism including a limiting reference part disposed on the mounting base and a limiting abutment part disposed on the scraping component. When the scraping component rotates to the avoidance position, the limiting abutment part separates from the limiting reference part. When the scraping component rotates to the initial position, the limiting abutment part abuts against the limiting reference part and is used to restrict the scraping component located in the initial position from rotating away from the avoidance position.

[0024] Further, a specific structure of the protective component is provided, the protective component including at least one arc-shaped protective rod connected to the vessel body and covering the outside of the temperature measuring tube.

[0025] A further provision provides a specific structure for the reset elastic element, wherein the reset elastic element is a torsion spring.

[0026] Furthermore, the vessel body is connected to a drive mechanism that is connected to the central shaft and used to drive the central shaft to rotate. The drive mechanism includes a bracket and a reduction motor. The bracket is connected to the top of the vessel body, and the reduction motor is connected to the bracket and connected to the central shaft to drive the central shaft to rotate.

[0027] Using the above technical solution, when the central shaft is driven to rotate, it will cause the first lower slurry, the second lower slurry, the first upper slurry, and the second upper slurry to rotate, which in turn will cause all the scrapers to rotate. When the first lower slurry, the second lower slurry, the first upper slurry, and the second upper slurry rotate, they can stir the materials in the vessel. When the scrapers rotate, they can scrape off the material adhering to the inner wall of the vessel. Scraping off the material on the inner wall of the vessel can enhance the heat transfer effect of the vessel, thereby improving the quality of the reaction and reducing side reactions. The inner wall of the vessel includes an inner side wall and an inner bottom wall. During the rotation of the first lower slurry, the second lower slurry, the first upper slurry, and the second upper slurry, the temperature measuring tube can pass through the first interval and the second interval. The purpose of setting the first interval and the second interval is to avoid the temperature measuring tube, thereby preventing collision and interference between the temperature measuring tube and the stirring paddle, and allowing a thermometer to be installed in the temperature measuring tube to measure the reaction temperature at the bottom of the vessel.

[0035] To make the content of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0036] like Figure 1 , 2 As shown, a stirred dispersion reactor includes a reactor body 1, a temperature measuring tube 2, a stirring paddle 3 and multiple scrapers 4. The stirring paddle 3 includes a central shaft 5, a first lower slurry 6, a second lower slurry 7, a first upper slurry 8 and a second upper slurry 9.

[0037] The temperature measuring tube 2 is connected to the lower end of the vessel body 1 and extends into the interior of the vessel body 1;

[0038] The central shaft 5 is rotatably connected to the vessel body 1 and extends into the interior of the vessel body 1;

[0039] The first lower slurry 6, the second lower slurry 7, the first upper slurry 8, and the second upper slurry 9 are all located inside the vessel body 1;

[0040] The first lower slurry 6 and the second lower slurry 7 are respectively connected to the lower end of the central shaft 5;

[0041] The first upper slurry 8 is connected to the central shaft 5 and is located above the first lower slurry 6;

[0042] The second upper slurry 9 is connected to the central shaft 5 and is located above the second lower slurry 7;

[0043] A first gap 10 is provided between the first lower slurry body 6 and the first upper slurry body 8 to avoid the temperature measuring tube 2, and a second gap 11 is provided between the second lower slurry body 7 and the second upper slurry body 9 to avoid the temperature measuring tube 2. Both the first gap 10 and the second gap 11 are located at the same height as the temperature measuring tube 2.

[0044] The first lower slurry 6, the second lower slurry 7, the first upper slurry 8, and the second upper slurry 9 are respectively connected to scrapers 4. The scrapers 4 connected to the first lower slurry 6 and the scrapers 4 connected to the second lower slurry 7 abut against the inner bottom wall of the vessel body 1, and the scrapers 4 connected to the first upper slurry 8 and the scrapers 4 connected to the second upper slurry 9 abut against the inner side wall of the vessel body 1.

[0045] Specifically, when the central shaft 5 is driven to rotate, it will cause the first lower slurry 6, the second lower slurry 7, the first upper slurry 8, and the second upper slurry 9 to rotate, which in turn will cause all the scrapers 4 to rotate. When the first lower slurry 6, the second lower slurry 7, the first upper slurry 8, and the second upper slurry 9 rotate, they can stir the materials in the vessel body 1. When the scrapers 4 rotate, they can scrape off the materials adhering to the inner wall of the vessel body 1. Scraping off the materials on the inner wall of the vessel body 1 can enhance the heat transfer effect of the vessel body 1, thereby improving the quality of the reaction and reducing side reactions. The inner wall of the vessel body 1 includes the inner side wall and the inner bottom wall. During the rotation of the first lower slurry 6, the second lower slurry 7, the first upper slurry 8, and the second upper slurry 9, the temperature measuring tube 2 can pass through the first interval 10 and the second interval 11. The purpose of setting the first interval 10 and the second interval 11 is to avoid the temperature measuring tube 2, thereby preventing the temperature measuring tube 2 from colliding and interfering with the stirring paddle 3, and allowing a thermometer to be installed in the temperature measuring tube 2 to measure the reaction temperature at the bottom of the vessel 1. In this embodiment, one end of the temperature measuring tube 2 extends into the interior of the vessel 1, and the other end of the temperature measuring tube 2 extends out of the vessel 1.

[0046] like Figure 1 , 2 As shown, the first lower slurry 6 and the second lower slurry 7 are at the same height position and are 180° apart in the circumferential direction. The first upper slurry 8 and the second upper slurry 9 are at the same height position and are 180° apart in the circumferential direction.

[0047] like Figure 1 , 2 As shown, a plurality of lower blades 12 are connected to the central shaft 5 and are arranged in a circumferentially at intervals. The lower blades 12 are located above the first lower slurry body 6 and the second lower slurry body 7 and below the first upper slurry body 8 and the second upper slurry body 9.

[0048] like Figure 1 , 2 As shown, a plurality of upper blades 13 are connected to the central shaft 5 and are arranged in a circumferentially at intervals. The upper blades 13 are located above the first upper impeller 8 and the second upper impeller 9.

[0049] like Figure 1 , 2 As shown, a first connecting rod 14 connects the first upper slurry body 8 and the first lower slurry body 6, and a second connecting rod 15 connects the second upper slurry body 9 and the second lower slurry body 7.

[0050] like Figures 1-6As shown, the stirring and dispersing reactor may also include a mounting base 16, a scraping component 17, a reset elastic component 18, a limiting mechanism, and a protective component 19;

[0051] The mounting base 16 is connected to the first connecting rod 14, and the scraping component 17 is rotatably connected to the mounting base 16 and has an initial position and a clearance position during the rotation relative to the mounting base 16.

[0052] The limiting mechanism is disposed between the mounting base 16 and the scraping component 17 and is used to restrict the scraping component 17 located in the initial position from rotating away from the avoidance position, but does not restrict the scraping component 17 located in the initial position from rotating toward the avoidance position;

[0053] When the scraping component 17 is in the initial position, one end of the scraping component 17 abuts against the inner wall of the vessel body 1, so that when the central shaft 5 rotates, it drives the first connecting rod 14, the mounting base 16 and the scraping component 17 to rotate together around the central shaft 5, thereby scraping off the material on the inner wall of the vessel body 1 through the scraping component 17.

[0054] The protective component 19 is connected to the vessel body 1 and covers the outside of the temperature measuring tube 2. The scraping component 17, the protective component 19, the temperature measuring tube 2, the first interval 10 and the second interval 11 are all located at the same height. When the scraping component 17 rotates with the central axis 5 to abut against the protective component 19, the protective component 19 is used to push the scraping component 17 to rotate from the initial position to the avoidance position.

[0055] The reset elastic element 18 is installed between the scraper component 17 and the mounting base 16 and is used to drive the scraper component 17 to rotate from the avoidance position to the initial position when the scraper component 17 disengages from the protective component 19.

[0056] Specifically, during the rotation of the stirring paddle 3, both the temperature measuring tube 2 and the protective component 19 pass through the first interval 10 and the second interval 11, thereby avoiding collision interference with the stirring paddle 3. When the scraping component 17 does not abut against the protective component 19, the scraping component 17 will rotate to its initial position under the drive of the reset elastic element 18. At this time, the limiting mechanism will limit the scraping component 17 in the initial position, and the scraping component 17 will abut against the inner wall of the vessel body 1. When the central shaft 5 is driven to rotate, it will drive the first connecting rod 14, the mounting base 16 and the scraping component 17 to rotate together around the central shaft 5, thereby scraping off the material on the inner wall of the vessel body 1 through the scraping component 17. Specifically, due to the presence of the first interval 10 and the second interval 11, the scraper 4 cannot scrape off the material on the inner wall of the vessel 1 that is at the same height as the temperature measuring tube 2. However, the scraping component 17 is positioned at the same height as the temperature measuring tube 2, the first interval 10, and the second interval 11. Therefore, the scraping component 17 can effectively scrape off the material that the scraper 4 cannot remove. More specifically, as... Figure 3 , 5 As shown, when the scraping component 17 rotates with the central axis 5 to abut against the protective component 19, the protective component 19 will push the scraping component 17 to rotate from its initial position to a clearance position, and then the scraping component 17 can pass through the protective component 19, as shown. Figure 4 , 6 As shown, when the scraping component 17 rotates with the central axis 5 until it disengages from the protective component 19, the reset elastic element 18 drives the scraping component 17 to rotate back from the avoidance position to the initial position, so that the scraping component 17 can abut against the inner wall of the vessel body 1 and scrape off the material on the inner wall of the vessel body 1. The protective component 19 prevents the scraping component 17 from touching the temperature measuring tube 2. In this embodiment, the scraping component 17 is located in the first interval 10.

[0057] like Figure 5 , 6 As shown, the limiting mechanism may include a limiting reference part 20 provided on the mounting base 16 and a limiting abutment part 21 provided on the scraping component 17. When the scraping component 17 rotates to the avoidance position, the limiting abutment part 21 separates from the limiting reference part 20. When the scraping component 17 rotates to the initial position, the limiting abutment part 21 abuts against the limiting reference part 20 and is used to restrict the scraping component 17 in the initial position from rotating away from the avoidance position. Therefore, the scraping component 17 in the initial position can only rotate toward the avoidance position and cannot rotate away from the avoidance position.

[0058] like Figures 2-5As shown, the protective component 19 may include at least one arc-shaped protective rod 22 connected to the vessel body 1 and covering the outside of the temperature measuring tube 2; in this embodiment, two arc-shaped protective rods 22 are provided.

[0059] like Figure 5 , 6 As shown, the reset elastic element 18 can be a torsion spring; specifically, the structure and installation method of the torsion spring are existing technologies well known to those skilled in the art, and will not be described in detail in this embodiment.

[0060] like Figure 1 As shown, the vessel body 1 is connected to a drive mechanism that is connected to the central shaft 5 and is used to drive the central shaft 5 to rotate. The drive mechanism includes a bracket 23 and a reduction motor 24. The bracket 23 is connected to the top of the vessel body 1, and the reduction motor 24 is connected to the bracket 23 and connected to the central shaft 5 and is used to drive the central shaft 5 to rotate.

[0061] In summary, when the central shaft 5 is driven to rotate, it will cause the first lower slurry 6, the second lower slurry 7, the first upper slurry 8, and the second upper slurry 9 to rotate, which in turn will cause all the scrapers 4 to rotate. When the first lower slurry 6, the second lower slurry 7, the first upper slurry 8, and the second upper slurry 9 rotate, they can stir the materials in the vessel body 1. When the scrapers 4 rotate, they can scrape off the materials adhering to the inner wall of the vessel body 1. Scraping off the materials on the inner wall of the vessel body 1 can enhance the heat transfer effect of the vessel body 1, thereby improving the quality of the reaction and reducing side reactions. The inner wall of the vessel body 1 includes the inner side wall and the inner bottom wall. During the rotation of the first lower slurry 6, the second lower slurry 7, the first upper slurry 8, and the second upper slurry 9, the temperature measuring tube 2 can pass through the first interval 10 and the second interval 11. The purpose of setting the first interval 10 and the second interval 11 is to avoid the temperature measuring tube 2, thereby avoiding collision and interference between the temperature measuring tube 2 and the stirring paddle 3, and thus allowing a thermometer to be installed in the temperature measuring tube 2 to measure the reaction temperature at the bottom of the vessel 1.

[0062] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
