[0002] The cooling structure of the tablet making machine for sodium sulfide production is a cooling system designed for tablet making machines in the sodium sulfide production process. The system mainly includes a drum, the center of which passes through a hollow shaft, and the drum rotates around this shaft. Inside the drum, there are multiple water distribution rings, which are connected to the main water pipe through multiple radial branches. When cooling water flows through the main water pipe, the cooling water will be introduced into the water distribution ring through these radial branches. On the water distribution ring, there are multiple nozzles, and the water spraying direction of these nozzles is opposite to the rotation direction of the drum.
