Detailed Implementation

[0017] 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.

[0018] Please see Figure 1 - Figure 4 The embodiments provided by this utility model are as follows: The trifluoromethylaniline reactor has a multi-stage stirring structure, including a rotating shaft 1, with two vertical stirring mechanisms installed on the outer side of the rotating shaft 1. A sliding hole 4 is provided on the outer side of the rotating shaft 1, and a sliding column 10 is slidably installed in the sliding hole 4. A transverse stirring mechanism is installed on both sides of the sliding column 10. Two push rods 5 are rotatably mounted on both sides of the sliding column 10, and the two push rods 5 on the same side are rotatably connected to the vertical stirring mechanism on the same side. A movable ring 11 is fixedly installed at the top of the sliding column 10 and slidably sleeved on the rotating shaft 1. A rotating ring 12 is rotatably installed on the outer ring surface of the movable ring 11. An electric telescopic rod 2 and a motor 3 are arranged above the rotating shaft 1. The movable end of the electric telescopic rod 2 is fixedly connected to the side of the rotating ring 12. The output shaft of the motor 3 is fixedly connected to the top of the rotating shaft 1. Four arc-shaped rods 13 are fixedly installed at the bottom of the rotating shaft 1. The four arc-shaped rods 13 are installed in conjunction with two horizontal stirring mechanisms and two vertical stirring mechanisms.

[0019] like Figure 1 and Figure 2As shown, the horizontal stirring mechanism includes multiple horizontal stirring rods 9. The lowest horizontal stirring rod 9 is rotatably connected to the side of the sliding column 10, while the remaining horizontal stirring rods 9 are fixedly connected to the side of the sliding column 10. A movable sleeve 15 is slidably sleeved on the lowest horizontal stirring rod 9, and the bottom end of the movable sleeve 15 is rotatably mounted on the end of the adjacent arc-shaped rod 13 away from the rotating shaft 1. The movement of the sliding column 10 causes the multiple horizontal stirring rods 9 to move downward, changing their horizontal position. The downward movement of the sliding column 10 causes the lowest horizontal stirring rod 9 to rotate, thereby causing the movable sleeve 15 to rotate. This allows the lowest horizontal stirring rod 9 to tilt, thus adapting to the conical inner wall of the reactor.

[0020] like Figure 3 and Figure 4 As shown, the vertical stirring mechanism includes a rectangular column 8 fixedly installed on the outer side of the rotating shaft 1. A rectangular sleeve 6 is slidably sleeved on the rectangular column 8. Multiple vertical stirring rods 7 are fixedly installed at the bottom of the rectangular sleeve 6. The bottom ends of two push rods 5 on the same side as the rectangular column 8 are rotatably installed on the two sides of the rectangular sleeve 6. Sliding rods 16 are slidably installed at the bottom ends of the multiple vertical stirring rods 7. U-shaped rods 17 are fixedly installed at the bottom ends of the multiple sliding rods 16. Moving columns 18 are fixedly installed on the inner walls of both sides of the U-shaped rods 17. Arc grooves 14 are opened on both sides of the two arc-shaped rods 13 away from the horizontal stirring rods 9. The two moving columns 18 on the U-shaped rods 17 extend into the two arc grooves 14 respectively. When it is necessary to adjust the vertical and horizontal stirring positions, the electric telescopic rod 2 is activated. The movable end of the electric telescopic rod 2 extends and retracts, causing the rotating ring 12 to move downward. The movement of the rotating ring 12 causes the moving ring 11 and the sliding column 10 to move. The movement of the sliding column 10 causes the push rod 5 to rotate, thereby causing the two rectangular sleeves 6 to move away from each other. This causes the vertical position of the multiple vertical stirring rods 7 to change. When the vertical stirring rod 7 moves, it will cause the sliding rod 16 to move. The movement of the sliding rod 16 will cause the U-shaped rod 17 to move. The U-shaped rod 17 will cause the two moving columns 18 to slide in the two arc-shaped grooves 14 respectively. This allows the sliding rod 16 to extend and retract in the groove on the vertical stirring rod 7, thus adapting to the conical inner wall of the reactor.

[0021] like Figure 1 and Figure 3 As shown, multiple vertical stirring rods 7 are arranged at equal intervals along the direction of the rectangular column 8, and multiple horizontal stirring rods 9 are arranged at equal intervals along the direction of the rotating shaft 1. The advantage of this arrangement is that it enables uniform stirring in both the vertical and horizontal directions.

[0022] like Figure 4 As shown, a groove is provided at the bottom end of the vertical stirring rod 7, and the bottom end of the slide rod 16 is slidably installed in the groove. The slide rod 16 and the groove allow the slide rod 16 to move up and down.

[0023] Working principle: In use, the electric telescopic rod 2 and the motor 3 can be installed on the top of the reactor. During stirring, the motor 3 is started, and the output end of the motor 3 rotates, driving the sliding column 10 and the moving ring 11 to rotate. The outer part of the moving ring 11 is rotatably connected to the rotating ring 12, so that the rotating ring 12 does not move. The rotating shaft 1 rotates, driving the two rectangular columns 8, the two rectangular sleeves 6, the multiple vertical stirring rods 7 and the multiple sliding rods 16 to rotate, so that stirring can be carried out in the vertical direction. At the same time, the sliding column 10 rotates, driving the multiple horizontal stirring rods 9 to rotate, so that stirring can be carried out in the horizontal direction. When it is necessary to adjust the vertical and horizontal stirring positions, the electric telescopic rod 2 is activated. The movable end of the electric telescopic rod 2 extends and retracts, causing the rotating ring 12 to move downward. The movement of the rotating ring 12 causes the moving ring 11 and the sliding column 10 to move. The movement of the sliding column 10 causes the push rod 5 to rotate, thereby causing the two rectangular sleeves 6 to move away from each other. This causes the vertical position of the multiple vertical stirring rods 7 to change. When the vertical stirring rod 7 moves, it will cause the sliding rod 16 to move. The movement of the sliding rod 16 will cause the U-shaped rod 17 to move. The U-shaped rod 17 will cause the two moving columns 18 to slide in the two arc-shaped grooves 14 respectively. This allows the sliding rod 16 to extend and retract in the groove on the vertical stirring rod 7, thus adapting to the conical inner wall of the reactor.

[0024] At the same time, the sliding column 10 moves, causing multiple horizontal stirring rods 9 to move downward, which changes the horizontal position of the multiple horizontal stirring rods 9. The downward movement of the sliding column 10 causes the bottom horizontal stirring rod 9 to rotate, which in turn causes the moving sleeve 15 to rotate, so that the bottom horizontal stirring rod 9 can tilt to fit the conical inner wall of the reactor.

[0025] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
