Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically to a rate-limited dropping reaction vessel. Background Technology

[0002] A reaction vessel is a common reaction container in chemical industrial production, mainly used for compound synthesis. In the synthesis of some compounds, auxiliary materials, which are typically added to the main material, need to be slowly and at a controlled rate dripped into the reaction vessel. Then, the auxiliary materials are uniformly mixed with the main material according to processing requirements. Most existing reaction vessels have a simple structure, and when it is necessary to add auxiliary materials at a controlled rate to ensure sufficient reaction with the main material, the stirring and feeding rates cannot be adjusted according to the specific needs of the processing, thus limiting their functionality. Therefore, we propose a rate-controlled dripping reaction vessel. Utility Model Content

[0003] The purpose of this invention is to provide a rate-limited dropping reaction vessel to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rate-limiting dripping reaction vessel, comprising a reaction vessel body, a support frame fixedly mounted at the bottom of the reaction vessel body, a first feed pipe and a second feed pipe fixedly connected to the top of the reaction vessel body, a rate-limiting mechanism fixedly connected to the end of the first feed pipe, a discharge pipe fixedly connected to the bottom of the reaction vessel body, a switching valve fixedly mounted inside the discharge pipe, and a stirring mechanism mounted inside the reaction vessel body.

[0005] Preferably, the stirring mechanism includes a first drive motor and a second drive motor, which are respectively fixedly mounted on the top and bottom of the reactor body. A stirring frame is rotatably connected inside the reactor body, and a stirring shaft is rotatably connected inside the stirring frame. The output end of the first drive motor is fixedly connected to the top of the stirring frame, and the output end of the second drive motor is fixedly connected to the bottom of the stirring shaft.

[0006] Preferably, the speed limiting mechanism includes a speed limiting tube, in which a first fixing plate and a second fixing plate are fixedly mounted. The first fixing plate and the second fixing plate are respectively provided with through holes. A mounting bracket is fixedly mounted in the speed limiting tube through a fixing shaft.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: A rate-limiting dripping reactor is provided with a rate-limiting mechanism at the end of the first feed pipe. The first and second fixed plates in the rate-limiting mechanism adopt a double buffering method, which can effectively limit the addition speed of auxiliary materials and improve the stability of auxiliary materials dripping into the reactor body. At the same time, the stirring mechanism located in the reactor body has been redesigned. The stirring rack and stirring shaft cooperate with each other to uniformly mix the main material and auxiliary material. During the reaction, the stirring rack or stirring shaft can be turned on according to production needs, which can meet more production needs, save costs, and reduce waste of resources.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution: a rate-limited dropping reaction vessel, including a reaction vessel body 1. A first feed pipe 2 and a second feed pipe 3 are fixedly connected to the top of the reaction vessel body 1. A rate-limiting mechanism 4 is fixedly installed on the top of the first feed pipe 2. The material to be reacted can be fed into the reaction vessel body 1 through the first feed pipe 2 and the second feed pipe 3. The rate-limiting mechanism 4 can control the feeding speed of the first feed pipe 2 into the reaction vessel body 1. A discharge pipe 5 is fixedly connected to the bottom of the reaction vessel body 1. The discharge pipe 5 is used to discharge the processed material to the outside. A switch valve 6 is fixedly installed in the discharge pipe 5. The switch valve 6 is a solenoid valve, electrically connected to an external power supply and an external controller. The switch valve 6 controls the opening and closing of the discharge pipe 5. A support frame 8 is fixedly installed at the bottom of the reaction vessel body 1. The support frame 8 supports and fixes the reaction vessel body 1.

[0018] like Figure 2 and Figure 3 As shown, a stirring mechanism 7 is installed inside the reactor body 1. The stirring mechanism 7 can mix the materials inside the reactor body 1. The stirring mechanism 7 includes a first drive motor 71 and a second drive motor 72. The first drive motor 71 and the second drive motor 72 are fixedly installed at the top and bottom of the reactor body 1, respectively. The first drive motor 71 and the second drive motor 72 are electrically connected to an external power supply and an external controller, respectively. The external controller can control the opening and closing of the first drive motor 71 and the second drive motor 72. A stirring frame 73 is rotatably connected inside the reactor body 1. A stirring shaft 74 is rotatably connected inside the stirring frame 73. The output end of the first drive motor 71 is fixedly connected to the top of the stirring frame 73 through a coupling. The first drive motor 71 drives the stirring frame 73 to rotate inside the reactor body 1. The output end of the second drive motor 72 is fixedly connected to the bottom of the stirring shaft 74 through a coupling. The second drive motor 72 drives the stirring shaft 74 to rotate inside the reactor body 1.

[0019] The first drive motor 71 and the second drive motor 72 rotate in opposite directions. When it is necessary to stir and mix the materials, the first drive motor 71 and the second drive motor 72 can be turned on, so that the stirring frame 73 and the stirring shaft 74 rotate in different directions, thereby accelerating the stirring and mixing of the materials in the reactor body 1. When the added materials are dripped into the reactor body 1 at a limited speed, the first drive motor 71 or the second drive motor 72 can be turned on according to the type of reaction, so that only the stirring frame 73 or the stirring shaft 74 can operate independently in the reactor body 1. This can achieve the purpose of saving energy and effectively stir and mix the materials added to the reactor body 1 later.

[0020] like Figure 4 and Figure 5As shown, the speed limiting mechanism 4 includes a speed limiting tube 41, which is detachably and fixedly connected to the first feed tube 2. A first fixing plate 42 and a second fixing plate 43 are fixedly mounted inside the speed limiting tube 41 from top to bottom. Through holes 44 are respectively opened in the first fixing plate 42 and the second fixing plate 43. The through holes 44 are fan-shaped, facilitating the flow of the added material. A mounting bracket 46 is fixedly mounted inside the speed limiting tube 41 via a fixing shaft 45. A third drive motor 47 is embedded in the mounting bracket 46. The third drive motor 47 is a dual-axis output motor, electrically connected to an external power supply and an external controller. The rotation of the output end of the third drive motor 47 is controlled by the external controller. The output end of the three drive motors 47 is fixedly connected to baffles 48 through the mounting bracket 46. The side walls of the two baffles 48 are rotatably connected to the middle of the first fixed plate 42 and the second fixed plate 43 through the rotating shaft 49, respectively. The two baffles 48 are in contact with the first fixed plate 42 and the second fixed plate 43, respectively. The third drive motor 47 drives the baffles 48 to rotate. The overlap of the controller with the through hole 44 in the first fixed plate 42 and the second fixed plate 43 can control the speed of the material passing through the speed limiting tube 41. The dual control method can effectively buffer the material and slow down the speed at which the material enters the reactor body 1, so that the material added to the reactor body 1 can be fully mixed with the material in the original reactor body 1.

[0021] Working principle: During use, the main material for the reaction enters the reactor body 1 through the second feed pipe 3. The auxiliary material that needs to be added to the main material to react with it is added through the first feed pipe 2. During the addition process, the feeding speed of the auxiliary material can be adjusted by the speed limiting mechanism 4. The dual speed limiting method can effectively slow down the speed at which the auxiliary material enters the reactor body 1. The auxiliary material entering the reactor body 1 can be mixed with the main material by the stirring mechanism 7. The stirring mechanism 7 uses a stirring frame 73 and a stirring shaft 74 to rotate in different directions, which can enhance the mixing effect of the auxiliary material and the main material. At the same time, the stirring frame 73 or the stirring shaft 74 can be turned on separately according to different mixing needs during the reaction process, thus saving energy.
