The invention relates to the technical field of environmental protection and recycling economy, particularly to a use method of special rinsing process equipment for preparation of activated clay. The method is characterized by including use methods of a rotary rinsing cylinder assembly, a carrier roller assembly, a drive gear assembly, a screw feeder, and a screw discharge apparatus. Compared with the rinsing pool rinsing process of the prior art, the activated clay rinsing process adopts a rotary rinsing cylinder assembly scheme, greatly saves the floor space, lowers the investment, and at the same time greatly reduces the consumption of water and power.
