[0002] In the pharmaceutical industry, palladium carbon is widely used as a catalyst for hydrogenation reduction reactions. Due to the high value of palladium, it needs to be recycled. Traditional palladium carbon recycling equipment includes metal filters, bag filters, and stacked filters. During the recycling process, if the amount of liquid is relatively large, the efficiency of palladium carbon filtration is often not high; all operations related to filtering liquid are basically all manual operations; during the unloading process of palladium carbon, more palladium carbon will be exposed to the environment. If the liquid contains solvents, the solvents will evaporate, so the on-site operating environment will be relatively poor.
