Moreover, during the reaction process, samples of raw materials at different depths in the reaction kettle need to be taken for detection at different time periods. The existing reaction kettles are generally integrally sealed, making it inconvenient to take samples. Content of the Utility Model

Embodiment 2

[0031] Based on the above-mentioned Embodiment 1, please refer to the appendix Figure 3 、 Figure 4 、 Figure 5 The sampling cylinders 31 and the stirring blades 41 are arranged in an alternating pattern.

[0033] Working principle and usage process of the utility model: Before the reaction, solid or powdered raw materials are placed into different feed bins 27 according to different types. After the raw materials enter the feed bins 27, they fall onto the electronic weigher 24. The electronic weigher 24 weighs the raw materials in the feed bins 27 and displays the weight on the monitor in real time. According to the data on the monitor, the raw materials poured into the feed bins 27 are adjusted to proportion the amounts of different types of raw materials, completing the proportioning of solid raw materials. After the liquid raw materials are assembled with metering containers, the kettle cover 11 is rotated and opened. After pouring in the liquid raw materials, the propulsion cylinder 22 is started. The propulsion cylinder 22 drives the movable drawer 26 towards the kettle body 1 through the push rod 221. The movable drawer 26 pushes the raw materials in the feed bins 27 to the upper end of the kettle body 1 and falls into the kettle body 1 to complete the feeding. After the propulsion cylinder 22 retracts and returns to its original position, the kettle cover 11 is installed and fixed, and then the reaction starts. At this time, the stirring motor 4 is started. The stirring motor 4 drives the stirring blades 41 to stir the raw materials in the kettle body 1 to make them mix better. When sampling is required after mixing for a period of time, after selecting the sampling cylinder 31 at the corresponding height according to the requirements, hold the turntable 33 on the outer wall of the sampling column 32 of the sampling cylinder 31 and drive the sampling column 32 to rotate slowly. When the connecting hole 321 on the sampling column 32 rotates to correspond to the sampling hole 311 on the sampling cylinder 31, the reaction liquid in the kettle body 1 flows out of the kettle body 1 in sequence through the sampling hole 311, the connecting hole 321 and the output hole 322 to complete the sampling.
