[0039] The working principle of the present invention is as follows: the raw material in the raw material tank 101 enters the preheater 103 through the pipeline and the feed pump 102, and after being preheated in the preheater 103, the raw material enters the three-effect separator 105 through the feed pipe 104, and the material is continuously circulated in the three-effect separator 105, the three-effect circulation pipe 107 and the three-effect heater 109 through the three-effect forced circulation pump 108, so as to achieve the purpose of evaporating a part of the water, and the material enters the two-effect evaporation component 4 through the three-to-two circulation pump 110 and the three-to-two feed pipeline 406, and the material is continuously circulated between the two-effect separator 401 and the two-effect heater 404 through the two-effect forced circulation pump 403, and then enters the first-effect evaporation component 5 through the two-to-one circulation pump 405 and the two-to-one feed pipeline 506, and then enters the first-effect evaporation component 5 through the first-effect forced circulation pump 403. The forced circulation pump 503 of the first effect causes the material to circulate continuously between the first effect separator 501 and the first effect heater 504 to achieve the purpose of evaporating part of the water. The concentration of the material increases continuously during the circulation process. The material is discharged into the thickening kettle 601 through the first effect discharge pump 505 and the first effect discharge pipe 602. After being filtered by the filter 603, it is fixed in a bag and transported away.

The secondary steam generated by the three-effect separator 105 enters the preheater 103 and the condenser 111 through the three-effect steam pipe 106, and then condenses into water and is discharged to the condensate tank 112. Finally, it is discharged from the system through the condensate pump. When the high-temperature steam enters the separator, the gas in the heating cylinder 202 pushes the partition 204 to move outward after absorbing heat and expanding. The gas enters the radiator 207 through the channel and pushes the second piston to drive the second crankshaft connecting rod to move and rotate the cylinder 208. The rotation of the flywheel 206 connected to the cylinder 208 drives the partition 204 to move inward, and the hot air in the heating cylinder 202 is discharged to the radiator 207. After the gas in the radiator 207 is cooled, the air pressure decreases, and the external gas pushes the second piston inward, and the cold air enters the heating cylinder. 202, a new round of gas endothermic expansion begins, which is continuously circulated and drives the transmission belt 209 on the cylinder 208 to rotate, and then the pulley 210 rotates, converting heat energy into kinetic energy to power the equipment, so that the rotating shaft 308 rotates, and the rotating shaft 308 drives the second bevel gear 307 to rotate, and then the first bevel gear 306 meshing therewith rotates, and the rotation of the first bevel gear 306 drives the rotating rod 305 to rotate, so that the upper cleaning frame 309 on the top of the rotating rod 305 cleans the impurities on the filter screen 302 and the impurities on the upper inner wall of the filter cartridge 301 through the bristles 310, and the bristles 310 on both sides of the lower cleaning frame 311 at the bottom of the rotating rod 305 clean the impurities on the lower inner wall of the filter cartridge 301, so as to prevent the impurities from affecting the filtering effect of the filter screen 302.At the same time, a dynamic sealing ring 304 is provided at the connection between the rotating rod 305 and the support frame 303, so that the interior of the support frame 303 is in a sealed state relative to the separator, reducing the influence of the high temperature in the separator on the bevel gear transmission, which is beneficial to prolonging the service life of the bevel gear.
