Description

Technical Field

[0001] This utility model relates to the field of chemical reaction apparatus technology, and in particular to a 2-chloro-5-aminotrifluorotoluene reaction apparatus. Background Technology

[0002] 2-Chloro-5-aminotrifluorotoluene is an important organic synthesis intermediate, widely used in pharmaceuticals, pesticides, dyes and other fields. Its synthesis usually involves chlorination, nitration and reduction of the benzene ring, and most of these reactions are carried out in a reaction apparatus.

[0003] In the synthesis of 2-chloro-5-aminotrifluorotoluene, the stirring mechanism in the reaction apparatus is crucial for the thorough mixing of the reactants. However, existing stirring mechanisms typically employ only simple impeller structures, which have limited mixing efficiency and can easily lead to uneven local concentrations and poor mass transfer in the reaction system, thereby affecting the reaction rate and product yield. Therefore, to solve this problem, designing a 2-chloro-5-aminotrifluorotoluene reaction apparatus is something we need to consider. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a 2-chloro-5-aminotrifluorotoluene reaction apparatus. To address usability issues, it incorporates a lifting and stirring mechanism and a rotating mechanism. By starting a motor, the perforated plate and circular mesh plate rotate synchronously, stirring and mixing the reactants. Simultaneously, by controlling the telescopic rod to simultaneously lift the perforated plate and circular mesh plate, the mixing effect is further improved, ensuring product yield.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A 2-chloro-5-aminotrifluorotoluene reaction apparatus includes a vessel body with an observation window on the front side; a lifting and stirring mechanism, comprising a telescopic rod mounted on the upper end of the vessel body, a lifting plate fixedly connected to the telescopic end of the telescopic rod, a first rotating shaft rotatably connected to the lower end of the lifting plate, the upper end of the first rotating shaft penetrating the lifting plate and fixedly connected to a rectangular connecting rod, and multiple perforated plates and multiple circular mesh plates fixed on the first rotating shaft; and a rotation mechanism for controlling the rotation of the first rotating shaft.

[0007] Preferably, the rotating mechanism includes a motor installed at the upper end of the vessel body, a second rotating shaft is rotatably connected to the inner top of the vessel body, the upper end of the second rotating shaft passes through the inner top of the vessel body and is fixedly connected to the output shaft of the motor, and a rectangular inner groove is vertically opened at the lower end of the second rotating shaft.

[0008] Preferably, the telescopic rod is an electric telescopic rod, and the rectangular connecting rod is slidably connected to the inner wall of the rectangular inner groove.

[0009] Preferably, two heating plates are provided inside the inner wall of the vessel, and both heating plates are arc-shaped.

[0010] Preferably, a discharge pipe is provided at the lower end of the vessel body, and an exhaust pipe is provided at the upper end of the vessel body.

[0011] Preferably, a feed pipe is provided on the front side of the vessel body, and an air inlet pipe is provided on the right side of the vessel body.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] The system is equipped with a lifting and stirring mechanism and a rotating mechanism. By starting the motor, the second and first rotating shafts are driven to rotate, which in turn drives multiple perforated plates and multiple circular mesh plates to rotate synchronously. This can stir and mix the reactants in the reactor. At the same time, by controlling the telescopic rod, the lifting plate is driven to rise and fall in a cycle, which can also drive multiple perforated plates and multiple circular mesh plates to rise and fall synchronously. This further improves the mixing effect of the reactants in the reactor. Compared with the traditional simple stirring blade structure, it effectively improves the mixing efficiency of the reactants and ensures the actual reaction rate and product yield.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4 A 2-chloro-5-aminotrifluorotoluene reaction apparatus includes a vessel body 1. Two heating plates 11, both arc-shaped, are installed inside the inner wall of the vessel body 1. Heating wires are installed within each heating plate 11. A temperature sensor (not shown) is also installed inside the vessel body 1. These sensors, in conjunction with the heating plates 11, heat the reactants inside the vessel body 1 and maintain a suitable reaction temperature. A discharge pipe 12 is installed at the lower end of the vessel body 1, and a sealing valve (default closed) is installed within the discharge pipe 12 for recovering reactants. An exhaust pipe 1 is installed at the upper end of the vessel body 1. 3. A sealing valve (default closed) is installed in the exhaust pipe 13 to recover the waste gas generated by the reaction. A feed pipe 14 is installed on the front side of the vessel body 1, and a sealing valve (default open) is installed in the feed pipe 14 to fill the vessel body 1 with the reaction material. An air inlet pipe 15 is installed on the right side of the vessel body 1, and a sealing valve (default open) is installed in the air inlet pipe 15 to fill the vessel body 1 with the gas required for the reaction. An observation window 16 is installed on the front side of the vessel body 1, which allows the staff to observe the reaction of the material in the vessel body 1.

[0021] The system also includes a lifting and stirring mechanism, which includes a telescopic rod 2 installed on the upper end of the vessel body 1. The telescopic rod 2 is an electric telescopic rod. The telescopic end of the telescopic rod 2 is fixedly connected to a lifting plate 3. The lower end of the lifting plate 3 is rotatably connected to a first rotating shaft 4. The upper end of the first rotating shaft 4 passes through the lifting plate 3 and is fixedly connected to a rectangular connecting rod 5. Multiple perforated plates 6 and multiple circular mesh plates 7 are fixed on the first rotating shaft 4. By controlling the rotation of the multiple perforated plates 6 and multiple circular mesh plates 7, the reaction materials in the vessel body 1 can be fully mixed.

[0022] The system also includes a rotating mechanism for controlling the rotation of the first rotating shaft 4. The rotating mechanism includes a motor 8 mounted on the upper end of the vessel body 1. A second rotating shaft 9 is rotatably connected to the inner top of the vessel body 1. The upper end of the second rotating shaft 9 passes through the inner top of the vessel body 1 and is fixedly connected to the output shaft of the motor 8. A rectangular inner groove 10 is vertically opened at the lower end of the second rotating shaft 9. A rectangular connecting rod 5 is slidably connected to the inner wall of the rectangular inner groove 10, which can ensure that the first rotating shaft 4 can also rotate synchronously with the second rotating shaft 9 when it is raised and lowered.

[0023] In this invention, during use, the reactants are first filled into the vessel 1 through the feed pipe 14 (the reactants must not exceed the lifting plate 3). Then, the sealing valve in the feed pipe 14 is closed, and the gas required for the reaction is filled into the vessel 1 through the air inlet pipe 15. After the filling is complete, the sealing valve in the air inlet pipe 15 is closed, and the two electric heating plates 11 and the motor 8 are started. The two electric heating plates 11 can heat the reactants in the vessel 1 and maintain a suitable reaction temperature. The motor 8 can drive the second rotating shaft 9 to rotate, which in turn drives the rectangular connecting rod 5 and the first rotating shaft 4 to rotate synchronously, and drives multiple perforated plates 6 and multiple circular mesh plates 7 to rotate synchronously. The multiple perforated plates 6 and multiple circular mesh plates 7 can stir the reactants in the vessel 1 to ensure that the reactants are fully mixed, thereby improving the reaction efficiency. During this process, the operator can observe the reaction in the vessel 1 through the observation window 16. After the reaction is completed, the sealing valve in the exhaust pipe 13 can be opened to recover the waste gas generated by the reaction. Then, the sealing valve in the discharge pipe 12 can be opened to recover the reactants in the vessel 1.

[0024] It is worth mentioning that when controlling the rotation of multiple perforated plates 6 and multiple circular mesh plates 7, the telescopic rod 2 can be controlled to drive the lifting plate 3 to circulate up and down, driving the first rotating shaft 4, multiple perforated plates 6 and multiple circular mesh plates 7 to rise and fall synchronously. This can further improve the full mixing of the reactants in the vessel 1. Compared with the traditional stirring blade structure, it improves the mixing efficiency and reaction efficiency of the reactants.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
