[0025] Example: Please refer to Figure 1 - Figure 6 This embodiment of a constant-temperature enamel-lined reactor for the preparation of fine chemicals includes: a stirred tank 1, with a liquid inlet pipe at the top for discharging liquid; a temperature sensor 2 fixedly connected to the inner wall of the stirred tank 1; an electric heating wire 3 fixedly connected to the inner wall of the stirred tank 1; a stirring shaft 4 rotatably connected to the top of the stirred tank 1; the stirring shaft 4 fixedly connected to the drive end of a drive assembly 5; the drive assembly 5 fixedly connected to the top of the stirred tank 1; and a valve 6 fixedly connected to the bottom of the stirred tank 1. The drive assembly 5 includes a servo motor, two sets of pulleys, a belt, and a belt frame; the two sets of pulleys are fixedly connected to the stirring shaft 4; and the temperature sensor 2, the electric heating wire 3, the drive motor 9, the weight sensor 12, and the electromagnetic spring 17 are electrically connected to a controller 7.

[0026] Among them, the side wall of the mixing tank 1 is fixedly connected to the controller 7, the top of the mixing tank 1 is fixedly connected to the limiting frame 8, the side wall of the limiting frame 8 is bolted to the drive motor 9, and the output shaft of the drive motor 9 drives the drive frame 11 to rotate and connect with the limiting frame 8.

[0027] At this time, the top of the limiting frame 8 is provided with a feed inlet 101, and the bottom of the limiting frame 8 is provided with a discharge port 10. The discharge port 10 passes through the top of the mixing vessel 1 and communicates with the mixing space inside the mixing vessel 1.

[0028] Among them, a weight sensor 12 is fixedly connected to the inner wall of the drive frame 11, and a receiving frame 13 is fixedly connected to the weight sensor 12. The inner wall of the receiving frame 13 is wrapped with a thin film layer 14. The inner wall of the limiting frame 8 is smooth. A rubber layer is provided at the opening in the top area of ​​the receiving frame 13. The rubber layer contacts and scrapes the inner wall of the limiting frame 8.

[0029] At this time, an air inlet 15 is provided through the side wall of the drive frame 11, a piston frame 16 is fixedly connected to the side wall of the drive frame 11, an electromagnetic spring 17 is fixedly connected to the inner side wall of the piston frame 16, the other end of the electromagnetic spring 17 is fixedly connected to the drive disk 18, the drive disk 18 is slidably connected to the piston frame 16, and the air inlet 15 is connected to the thin film layer 14 provided on the side wall of the receiving frame 13 through a connecting pipe.

[0030] The limiting frame 8, drive motor 9, discharge port 10, feed port 101, drive frame 11, weight sensor 12, receiving frame 13, thin film layer 14, air inlet 15, piston frame 16, electromagnetic spring 17, and drive disk 18 constitute a weighing assembly, and multiple weighing assemblies are provided on the top of the mixing vessel 1.

[0031] The working principle of the above embodiments is as follows:

[0032] When in use, the chemicals are prepared and mixed, and the prepared chemical components are placed into the container 13 through the feed port 101. The weight of the added chemicals is measured by the weight sensor 12 at the bottom of the container 13.

[0033] When the weight is added to the appropriate level, the drive motor 9 drives the drive frame 11 and the receiving frame 13 to rotate, causing the receiving frame 13 to rotate downwards. When the opening on the receiving frame 13 is above the discharge port 10, the medicine in the receiving frame 13 falls downwards through the discharge port 10 into the interior of the mixing vessel 1. Then, the control electromagnetic spring 17 is energized, and the electromagnetic spring 17 pushes the drive disk 18 to move. The drive disk 18 pushes the air inside the piston frame 16 into the film layer 14 through the air inlet 15. Then the electromagnetic spring 17 is de-energized and contracts. The electromagnetic spring 17 drives the drive disk 18 to move inwards. The drive disk 18 draws the air inside the film layer 14 into the interior of the piston frame 16. The film layer 14 continuously contracts and expands, making it convenient for the medicine remaining on the film layer 14 to fall downwards into the area of ​​the discharge port 10.

[0034] The control drive component 5 drives the stirring shaft 4 to rotate, and the stirring shaft 4 stirs and mixes the medicine and liquid inside. The internal temperature is sensed by the temperature sensor 2. When the temperature is low, the electric heating wire 3 is activated to heat the mixture. After the reaction is completed, the mixture is discharged to the outside through the valve 6.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
