[0002] Triphenylphosphine is an organic compound, also known as triphenol phenyl ester; triphenylphosphine, with the chemical formula C18H15P, molecular weight of 262.30, melting point of 78.5 - 81.5 °C, boiling point of 487.4 °C, flash point of 248.6 °C, is a white to light yellow crystalline powder and is insoluble in water; triphenylphosphine has a wide range of uses in the chemical industry and is an important catalyst for the synthesis of fine chemicals.
[0003] Based on the above, the inventor found that:
[0004] In the prior art, we need to add different catalysts, which are put in through several feeding ports. The catalyst feeding ports are concentrated, and the feeding mostly occurs on the liquid surface, which is prone to catalyst accumulation. In addition, some only have one feeding port, and the fed catalyst may contact the inside of the feeding port. When another catalyst is put in, new chemical reactions may occur between different catalysts, resulting in a reduction in reaction efficiency.
[0005] Therefore, in view of this, research and improvement are carried out on the existing structure, and a reaction device for producing triphenylphosphine is proposed to solve the above problems. Summary of the Utility Model
[0006] The technical problem to be solved by the utility model is that the traditional reaction device for triphenylphosphine has only one catalyst feeding port or the feeding ports are concentrated, which cannot avoid the contact of different catalysts and affects the reaction efficiency.
[0007] To solve the above problems, the technical solution proposed by the utility model is: a reaction device for producing triphenylphosphine, including a triphenylphosphine reaction kettle and a discharge pipe. A catalyst feeding assembly and a stirring assembly are arranged inside the triphenylphosphine reaction kettle. The catalyst feeding assembly is located in the middle of the stirring assembly, and the upper end of the catalyst feeding assembly extends outside the triphenylphosphine reaction kettle and is provided with a sealing cover or a guiding cover. The lower end of the catalyst feeding assembly is placed inside the triphenylphosphine reaction kettle.
[0008] Furthermore, the catalyst feeding assembly includes an inner pipe, a middle pipe, and an outer pipe. The inner pipe is fixedly connected to the middle pipe through a first connecting block, the middle pipe is fixedly connected to the outer pipe through a second connecting block, and the outer pipe is fixedly connected to the upper end of the triphenylphosphine reaction kettle.
[0009] Furthermore, the inner pipe, the middle pipe, and the outer pipe are of different lengths and are shortened in sequence from the inside to the outside. The bottoms of the inner pipe, the middle pipe, and the outer pipe are respectively fixedly connected to the inner bottom of the triphenylphosphine reaction kettle through connecting rods.
[0010] Furthermore, the inner tube, the middle tube, and the outer tube are all tubular structures, and grooves are respectively provided at the upper ends of the inner tube, the middle tube, and the outer tube. Three feeding covers are provided, and the upper ends of the three feeding covers are all open structures with different heights. A convex block adapted to the groove is provided at the lower end of the feeding cover, and the convex block is placed in the groove.
[0011] Furthermore, the bottom of the triphenylphosphine reactor is fixedly connected with a mounting plate through a fixing rod. The stirring assembly includes a motor, a first gear, a rotating shaft, and a stirring rod. Stirring blades are fixedly connected to the stirring rod inside the triphenylphosphine reactor. The motor is fixedly connected to the lower end of the mounting plate, and the output end of the motor is fixedly connected to the rotating shaft. The upper end of the rotating shaft is rotatably connected to the bottom of the triphenylphosphine reactor.
[0012] Furthermore, the stirring rod is rotatably connected to the inner top of the triphenylphosphine reactor, and the lower end of the stirring rod extends below the triphenylphosphine reactor and is rotatably connected to the mounting plate. The first gear is fixedly connected to the rotating shaft, and a second gear is equidistantly meshed outside the first gear. The second gear is located between the triphenylphosphine reactor and the mounting plate and is fixedly connected to the stirring rod.
[0013] Due to the adoption of the above technical solutions, the beneficial effects of the reaction device for producing triphenylphosphine of the present utility model are as follows:
[0014] 1. Through the setting of the catalyst feeding assembly, the inner tube, the middle tube, and the outer tube are all concentrated in the middle position of the triphenylphosphine reactor, making the catalyst feeding ports relatively concentrated. When feeding materials, there is no need to change different positions due to different positions of the feeding ports.
[0015] 2. Through the setting of three different channels of the inner tube, the middle tube, and the outer tube, different catalysts can be fed respectively, avoiding the contact between different catalysts and thus affecting the reaction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Please refer to Figures 1-5 As shown in the figure: The present utility model provides a reaction device for producing triphenylphosphine, including a triphenylphosphine reaction kettle 1 and a discharge pipe 2. A catalyst feeding assembly and a stirring assembly are arranged inside the triphenylphosphine reaction kettle 1. The bottom of the triphenylphosphine reaction kettle 1 is fixedly connected to a mounting plate 10 through a fixed rod 9. The stirring assembly includes a motor 11, a first gear 12, a rotating shaft 13, and a stirring rod 14.

The motor 11 is fixedly connected to the lower end of the mounting plate 10, and the output end of the motor 11 is fixedly connected to the rotating shaft 13. The upper end of the rotating shaft 13 is rotatably connected to the bottom of the triphenylphosphine reaction kettle 1.
[0027] As Figure 2 、 Figure 3As shown, the stirring rod 14 is rotatably connected to the inner top of the triphenylphosphine reaction kettle 1, and the lower end of the stirring rod 14 extends below the triphenylphosphine reaction kettle 1 and is rotatably connected to the mounting plate 10. The first gear 12 is fixedly connected to the rotating shaft 13. The outer side of the first gear 12 is equidistantly engaged with the second gear 16. The second gear 16 is located between the triphenylphosphine reaction kettle 1 and the mounting plate 10 and is fixedly connected to the stirring rod 14.
[0028] As Figure 3 , Figure 4 shown, the catalyst feeding assembly includes an inner tube 5, a middle tube 6, and an outer tube 7. The inner tube 5 is fixedly connected to the middle tube 6 through the first connecting block 17. The middle tube 6 is fixedly connected to the outer tube 7 through the second connecting block 18. The outer tube 7 is fixedly connected to the upper end of the triphenylphosphine reaction kettle 1. The inner tube 5, the middle tube 6, and the outer tube 7 are of different lengths and are successively shortened from the inside to the outside. The bottoms of the inner tube 5, the middle tube 6, and the outer tube 7 are respectively fixedly connected to the inner bottom of the triphenylphosphine reaction kettle 1 through the connecting rod 8.
[0029] As Figure 3 , Figure 4 shown, the catalyst feeding assembly is located in the middle of the stirring assembly, and the upper end of the catalyst feeding assembly extends outside the triphenylphosphine reaction kettle 1 and is provided with a sealing cover 3 or a material guiding cover 4. The lower end of the catalyst feeding assembly is placed inside the triphenylphosphine reaction kettle 1. The inner tube 5, the middle tube 6, and the outer tube 7 are all tubular structures, and grooves 19 are respectively provided at the upper ends of the inner tube 5, the middle tube 6, and the outer tube 7. There are three material guiding covers 4, and the upper ends of the three material guiding covers 4 are all open structures and have different heights.

[0030] The principle of a reaction device for producing triphenylphosphine of the present utility model is as follows:
[0031] A feed pipe is further provided at the upper end of the triphenylphosphine reaction kettle. The raw materials are poured into the triphenylphosphine reaction kettle through the feed pipe. The motor is started to drive the rotating shaft and the first gear to rotate. The first gear is engaged with the second gear, so as to drive the second gear to rotate. The second gear is fixedly connected to the stirring rod. The upper and lower ends of the stirring rod are respectively rotatably connected to the inner top of the triphenylphosphine reaction kettle and the upper end of the mounting plate. Therefore, the second gear drives the stirring rod and the stirring blades to rotate to mix the solution inside. When it is necessary to add the catalyst, the convex block of the material guiding cover is installed in the groove, and then the catalyst is respectively put into the inner tube, the middle tube, and the outer tube. The raw materials come into contact through the gaps formed by the lower ends of the inner tube, the middle tube, and the outer tube and the inner bottom of the triphenylphosphine reaction kettle, and in cooperation with the setting of the stirring assembly, the reaction is carried out. After use, the material guiding cover is removed and the sealing cover is covered.
[0032] With the setting of the catalyst feeding assembly in the present utility model, there are three catalyst feeding ports and their positions are concentrated, and at the same time, the contact between different catalysts is avoided, thus not affecting the reaction efficiency.
[0033] Before using the present utility model, it should be clearly understood that for the reaction conditions of triphenylphosphine, there are solvents, temperature and catalysts. Therefore, the present utility model also involves a heating assembly, which mainly heats the reaction liquid to enable it to reach the temperature required for the reaction, facilitating the reaction of triphenylphosphine. The above can all be achieved through the prior art. If other devices are required for cooperation, please add them according to the prior art by yourself to avoid low processing efficiency. The present utility model does not protect other contents, so the present utility model is not described in detail.
[0034] The above has described the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and without departing from the creative purpose of the present utility model, design similar structural manners and embodiments to this technical solution without creative efforts, they should all fall within the protection scope of the present utility model.
