Description

Technical Field

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

[0002] Toluenesulfonamide is a white crystalline or crystalline powder that can be used to synthesize other organic compounds, such as as a raw material for preparing intermediates for certain drugs, dyes, and pesticides. In the production process of toluenesulfonamide, through metathesis reaction, toluenesulfonamide can exchange ions or groups with other compounds to generate new compounds with different structures and properties. A metathesis reaction vessel is required when performing metathesis reaction on toluenesulfonamide.

[0003] The existing authorized publication number CN219663672U discloses a toluenesulfonylaminourea metathesis reactor, which includes an outer support body, support feet, a discharge port, a reactor body, a feed port, a drive component, a stirring component, and a temperature control component. This invention features a temperature control component that adjusts the internal temperature of the reactor body. This allows warm water to circulate within a heat-conducting pipe inside the reactor under the action of a water pump. Heat is then transferred to the reactor interior through the heat-conducting pipe, bringing the internal temperature closer to the optimal activation temperature of the catalyst. This enhances the catalyst's effect and increases the production reaction rate. A sliding door with an observation window allows for observation of the internal components while the temperature control component is operating, reducing the possibility of accidental contact and protecting the internal components from disruptions and reduced efficiency. In this metathesis reactor, a single vertical agitator is installed inside the reactor body to stir the raw materials. However, the vertical agitator primarily generates strong stirring near the blades and in the axial direction, while the fluid flow is slower near the reactor wall, resulting in poor mixing. Therefore, this metathesis reactor addresses these issues. Utility Model Content

A drive mechanism for driving the rotating shaft I and the four rotating shafts II to rotate synchronously is provided on the exterior of the outer vessel body. A feed pipe and a discharge pipe are connected and fixed to the inner vessel body.

[0023] 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.

[0024] Example

[0025] like Figure 1 , Figure 2 and Figure 3As shown, an embodiment of this utility model discloses a metathesis reaction vessel, comprising an outer vessel body 1 and an inner vessel body 2. The inner vessel body 2 is fixed inside the outer vessel body 1. A rotating shaft 3 and four rotating shafts 4 are rotatably connected to the inner vessel body 2 via bearings. One end of each rotating shaft 3 and four rotating shafts 4 slides through the outer vessel body 1 and extends to its exterior. Blades 5 are equidistantly fixed to the surface of the rotating shaft 3. A scraper 15, adapted to the shape of the bottom of the inner vessel body 2, is fixed to the surface of the rotating shaft 3. Using the scraper 15, the raw materials are mixed... To prevent the raw materials at the bottom of the inner vessel 2 from being unmixed, and during the feeding process, the feeding scraper 15 facilitates scraping the mixed raw materials inside the inner vessel 2 to the discharge pipe 9 for discharge. Two blades 6 are fixed on the surface of the rotating shaft 2. The outer vessel 1 is equipped with a drive mechanism 7 for driving the rotating shaft 1 3 and the four rotating shafts 2 4 to rotate synchronously. The inner vessel 2 is connected and fixed with a feed pipe 8 and a discharge pipe 9. A sealing plug 10 is inserted into the inside of the feed pipe 8. The bottom end of the discharge pipe 9 passes through the outer vessel 1 and extends to its outside.

[0026] The working principle and usage process of this utility model are as follows: In the process of using this metathesis reaction vessel, after toluenesulfonylaminourea and the catalyst that accelerates its metathesis reaction are fed into the inner vessel 2 through the feed pipe 8, the motor can be started to drive the rotating shaft 3 to rotate. After the rotating shaft 3 rotates, it can synchronously drive the four inclined rotating shafts 4 to rotate with the cooperation of the drive mechanism 7. When the rotating shaft 3 rotates, it will drive the blades 5 to vertically stir the raw materials inside the inner vessel 2, while the rotating shafts 4 will drive the blades 6 to horizontally stir the raw materials inside the inner vessel 2. Therefore, the uniformity and thoroughness of the mixing of the raw materials inside the inner vessel 2 can be further improved. Finally, after the raw materials are mixed, the valve on the discharge pipe 9 can be opened to discharge them. In addition, a sealing plug 10 is tightly inserted into the feed pipe 8, which can block the opening of the feed pipe 8 after the raw materials are fed, preventing dust and flocculent matter from entering the interior.

[0027] like Figure 1 , Figure 2 and Figure 5As shown, in some embodiments, the drive mechanism 7 includes a rotating frame 701 that rotates on the outer wall of the outer vessel body 1. A rotating ring 705 is fixed inside the rotating frame 701, and an annular rail 706 adapted to the rotating ring 705 is fixed on the outer wall of the outer vessel body 1, which can provide limiting support for the rotating frame 701, thereby making it more stable during rotation. Both the upper and lower surfaces of the rotating frame 701 are fixed with bevel gear rings 702, and the surfaces of the rotating shaft 4 are fixed with bevel gears 703. The bevel gears 703 are respectively meshed with the corresponding bevel gear rings 702. A rotating frame 704 is fixed to the surface of the rotating frame 701. The rotating frame 704 is fixed to the surface of the rotating shaft 3. In use, the rotating shaft 3 is driven to rotate by starting the motor. After the rotating shaft 3 rotates, it can drive the rotating frame 704 to rotate. After the rotating frame 704 rotates, it can drive the rotating frame 701 to rotate. After the rotating frame 701 rotates, it can drive the bevel gear ring 702 on its upper and lower surfaces to rotate. After the bevel gear ring 702 rotates, it can drive the bevel gear 703 that meshes with it to rotate. Finally, when the bevel gear 703 rotates, it can drive the rotating shaft 4 to rotate.

[0028] like Figure 1 and Figure 4 As shown, in some embodiments, a support base 11 is provided on the outer side of the outer vessel body 1. Support feet 12 are fixed in a circular array at the bottom of the support base 11. An annular plate 13 is provided inside the support base 11 and is fixed to the outer wall of the outer vessel body 1. A damping buffer 14 is fixed in a circular array between the support base 11 and the annular plate 13. When the vessel body is in use, the vibration of the vessel body due to operation will be transmitted to the annular plate 13. Then the vibration will be transmitted to the damping buffer 14 through the annular plate 13. Finally, under the action of the damping buffer 14, the vibration generated by the overall operation of the vessel body can be buffered. The support feet 12 can support the support base 11.

[0029] like Figure 3 As shown, in some embodiments, an arc-shaped heating plate 16 is fixed on the outer wall of the inner vessel 2. There are six arc-shaped heating plates 16. By arranging the arc-shaped heating plates 16 in a ring array on the outer wall of the inner vessel 2, the raw materials inside the inner vessel 2 will be heated more evenly when stirred.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
