Technical Field
[0001] This utility model relates to an additive device, and more particularly to a catalyst additive device for improving the yield of diphenylethanol ketone. Background Technology
[0002] Diphenylglycol (also known as benzyl alcohol ketone or diphenylethylene glycol ketone), with the chemical formula C14H12O2, is an organic compound that typically exists as white crystals or a colorless to pale yellow liquid. It has wide applications in the pharmaceutical, fragrance, and chemical industries. Diphenylglycol is mainly used as an intermediate in the synthesis of drugs and fragrances, especially in the pharmaceutical industry, where it is an important precursor for certain antibiotics and antifungal drugs. Catalyst addition refers to the specialized equipment used to add catalysts to a reaction system. Existing catalyst addition equipment adds the catalyst directly without achieving uniform distribution.
[0003] To address the above issues, a catalyst addition device needs to be designed to improve the yield of diphenylethanol ketone and solve the problem of uneven distribution during addition. Utility Model Content

[0011] The beneficial effects of this utility model are: 1. This utility model ensures that the catalyst is added to the reaction system in a precise and uniform manner by cooperating with the liquid plate and the rotating shaft, avoiding waste and uneven distribution.
[0012] 2. This invention uses the combination of a material cylinder and an ultrasonic vibrator to make the components inside the catalyst more uniform, ensuring uniform distribution of the catalyst and avoiding the increase of side reactions caused by excessively high or low local concentrations.

Detailed Implementation
[0020] Example: A catalyst addition device for improving the yield of diphenylethanol ketone, such as... Figures 1-4As shown, the system includes a base 1, a reactor 2, a material cylinder 3, a mounting bracket 4, a feed inlet 5, a one-way valve 7, a pipe 10, a rotating shaft 12, a liquid tray 15, and a conversion box 17. The reactor 2 is fixedly connected to the left side of the base 1, and the material cylinder 3 is bolted to the right side of the base 1. The mounting bracket 4 is bolted to the right side of the base 1. The feed inlet 5 is fixedly connected to the top right side of the material cylinder 3. The conversion box 17 is welded onto the mounting bracket 4. The rotating shaft 12 is rotatably connected inside the reactor 2. The bottom of the rotating shaft 12 has multiple liquid outlet holes. The lower part of the rotating shaft 12 is rotatably connected to the liquid tray 15. Pipes 10 are provided between the bottom of the material cylinder 3 and the left side of the conversion box 17, and between the right side of the liquid tray 15 and the left side of the conversion box 17. One-way valves 7 are installed on both pipes 10.
[0021] like Figure 3 As shown, it also includes an ultrasonic vibrator 6, which is installed on the left side of the material cylinder 3.
[0022] like Figure 3 As shown, it also includes a piston plate 8 and a connecting rod 9. The piston plate 8 is slidably connected inside the conversion box 17, and the connecting rod 9 is welded to the right side of the piston plate 8. The connecting rod 9 passes through the conversion box 17 and is slidably connected to the conversion box 17.
[0023] like Figure 4 As shown, it also includes an electric push rod 16. The electric push rod 16 is bolted to the rear top of the base 1, and the output shaft of the electric push rod 16 is fixedly connected to the connecting rod 9.
[0024] like Figure 3 As shown, it also includes a rack 14 and a gear 13. The rack 14 is welded to the middle of the connecting rod 9, and the gear 13 is fixedly connected to the upper part of the rotating shaft 12. The gear 13 meshes with the rack 14.
[0025] As shown in Figure 3, it also includes a nozzle 11, and the liquid outlet hole at the bottom of the rotating shaft 12 is provided with a nozzle 11.
[0026] When a catalyst is needed to increase the yield of diphenylethanol ketone, the catalyst is first added to the barrel 3 through the feed inlet 5. Then, the ultrasonic vibrator 6 is started to vibrate the catalyst in the barrel 3 to make the composition of the catalyst more uniform and ensure uniform distribution of the catalyst, avoiding excessively high or low local concentrations that could lead to increased side reactions. Then, the two one-way valves 7 are activated, and the catalyst in the barrel 3 flows into the conversion box 17 through the pipe 10. The electric push rod 16 is then activated, and the electric push rod 16 drives the piston plate 8 to move left and right through the connecting rod 9, thereby squeezing the catalyst in the conversion box 17 and feeding it into the conversion box through the pipe 10. The catalyst is added to the liquid tray 15, and at the same time, the connecting rod 9 drives the rack 14 to move left and right, causing the gear 13 to rotate back and forth. The rotation of the gear 13 drives the rotating shaft 12 to rotate back and forth, allowing the catalyst to flow into the reactor 2 through the nozzle 11 in an eccentric oscillation. This ensures that the catalyst is added to the reaction system in a precise and uniform manner, avoiding waste and uneven distribution, and facilitating subsequent operations by the staff. The cooperation between the gear 13 and the rack 14 improves the overall performance and practicality of the device, while ensuring that the structural design is innovative and efficient. Finally, the one-way valve 7, the ultrasonic vibrator 6 and the electric push rod 16 are closed.
