Detailed Embodiments

[0020] The technical solutions in the utility model will be further described below with reference to the drawings and embodiments.

[0021] As Figures 1 - 4 shown, an embodiment of the utility model provides a stripping kettle for rapid stripping of m-aminobenzotrifluoride, including:

[0022] A kettle body 1, on which a jacket or other heating components can be installed for heating during the stripping process; an upper cover is installed at the upper end of the kettle body 1, and a feeding pipe 5 is installed on the upper cover, through which materials can be added into the kettle body 1; a discharge pipe 3 is installed at the bottom of the kettle body 1, and a control valve 4 is installed on the discharge pipe 3 to discharge the materials; the feeding pipe 5 can be sealed by a screw plug; in addition, three support legs 2 are installed at the bottom of the kettle body 1, and leather pads are installed at the bottoms of the support legs 2 to stably support the kettle body 1.

[0023] Stirring assembly for precipitation; the stirring assembly includes a vertical pipe 12 that penetrates the upper cover and is rotatably arranged therewith. A motor 6 is installed on the upper cover. Transmission wheels 9 are installed on the output end of the motor 6 and on the vertical pipe 12. The two transmission wheels 9 are connected by a transmission belt 10. When the motor 6 operates, it drives the transmission wheel 9 to rotate. With the cooperation of the transmission wheel 9 and the transmission belt 10, the rotation of the vertical pipe 12 can be realized.

[0024] Wherein, a rotary joint 8 is installed at the upper end of the vertical pipe 12. A Y-shaped pipe 7 is fixedly installed on the rotary joint 8. Solenoid valves are installed at the other two ends of the Y-shaped pipe 7. The other two ends of the Y-shaped pipe 7 are respectively connected to a water pump and a supply pipeline of m-aminobenzotrifluoride. m-aminobenzotrifluoride can be transported into the Y-shaped pipe 7 through a pump body or the like. Due to the setting of the rotary joint 8, the Y-shaped pipe 7 is communicated with the vertical pipe 12 and does not affect the rotation of the vertical pipe 12; wherein, a check valve 11 is installed on the vertical pipe 12 to prevent backflow through the vertical pipe 12.

[0025] A connecting U-shaped pipe 15 is fixedly connected to the bottom of the vertical pipe 12. A stirring U-shaped pipe 13 is installed at the bottom of the connecting U-shaped pipe 15. A plurality of spray holes 14 which are inclined are arranged through the stirring U-shaped pipe 13. Two stirring vertical rods 16 are fixed between the connecting U-shaped pipe 15 and the stirring U-shaped pipe 13. A plurality of arc-shaped rods 17 are fixed between the two stirring vertical rods 16.

[0026] During use, m-aminobenzotrifluoride is transported into the vertical pipe 12 through the Y-shaped pipe 7, and finally transported into the stirring U-shaped pipe 13 through the connecting U-shaped pipe 15, and finally sprayed out through the spray holes 14 and sprayed on the inner wall of the kettle body 1. The kettle body 1 is heated by a jacket or the like. In this way, the sprayed m-aminobenzotrifluoride can be heated, and the subsequent heating efficiency can be improved; then the alcohol substance is added into the kettle body 1 through the feeding pipe 5;

[0027] The rotation of the vertical pipe 12 drives the rotation of the connecting U-shaped pipe 15 and the stirring U-shaped pipe 13, so as to realize the rotation of the stirring vertical rods 16 and the arc-shaped rods 17. Through the rotation of the stirring U-shaped pipe 13, the stirring vertical rods 16 and the arc-shaped rods 17, m-aminobenzotrifluoride and the alcohol substance can be fully mixed. Since the stirring U-shaped pipe 13 is in sliding contact with the inner wall of the kettle body 1, the inner wall of the kettle body 1 can be scraped and cleaned, preventing m-aminobenzotrifluoride from adhering to the inner wall of the kettle body 1. Thus, the material and the alcohol substance can be more fully mixed, and the precipitation treatment of m-aminobenzotrifluoride can be realized;

[0028] After processing and when cleaning the inner wall of the kettle body 1, clear water is transported to the vertical pipe 12 through the Y-shaped pipe 7. Finally, the clear water sprays out through the inclined spray holes 14. The clear water sprayed out by the spray holes 14 can clean the inner wall of the kettle body 1. Since the stirring U-shaped pipe 13 rotates, the inner wall of the kettle body 1 can be comprehensively cleaned and scraped. The inner bottom of the kettle body 1 is scraped and cleaned by the stirring U-shaped pipe 13. Open the control valve 4, and finally the wastewater generated after cleaning is discharged through the discharge pipe 3.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
