[0033] Working principle: Before using the device, first

[0034] Through the special feed pipe 8, we can accurately add the mixed liquid to be treated into the drum 4. Next, start the DC motor 3 in the device, and the drum 4 begins to rotate slowly. As the drum 4 rotates continuously, the mixed liquid is evenly distributed inside the drum 4 and is subjected to the centrifugal force, thereby achieving preliminary dehydration. After the preliminary dehydration is completed, the heating strip 10 starts to work to heat the inside of the drum 4. As the temperature inside the drum 4 continues to rise, the initially dehydrated substance begins to undergo an evaporation and dehydration process. At this time, water escapes from the substance in the form of steam, further reducing the water content of the dehydrated product. When the mixed liquid enters the drum 4 of the device for preliminary dehydration, a large amount of liquid separates from the drum 4 and falls on the reverse osmosis membrane 201, where Water will pass through the reverse osmosis membrane 201, while the solutes and impurities in the liquid will be retained on the other side of the membrane. After the filtered aqueous solution falls, the odor and organic compounds in the water will be removed by the powerful adsorption capacity of the activated carbon rod 202. At this time, the filtered water is pumped into the water tank 204 by starting the water pump 203. In order to ensure the safety of the water quality in the water tank 204, sterilization can be carried out by starting the ultraviolet lamp 205 to ensure that the water quality in the water tank 204 meets the sanitary standards. When the water in the water tank 204 needs to be used, just open the corresponding water pipe 206. The pipe cover 207 can effectively prevent water from flowing out of the water pipe 206, so that the water can be recycled.
