[0034] A specific application of this embodiment is as follows:

[0035] When the staff needs to use the device, first add the pretreated composite flame retardant solution into the cooling crystallization tank 201 through the feed port 202. Subsequently, start the cold air compressor 103. At this time, the cold air generated by the cold air compressor 103 will be transmitted into the transmission pipe 104. Then, the transmission pipe 104 will cool the cooling crystallization tank 201. Then, start the first motor 204. When the first motor 204 starts to rotate, it will drive the crown gear 206 to rotate through the rotating shaft 205. When the crown gear 206 starts to rotate, it will drive the gear 209 and the gear two 210 to rotate respectively. When the gear 209 and the gear two 210 start to rotate, they will drive the sleeve rods 207 and the rotating rods 208 connected to them to rotate respectively. When the rotating rod 208 starts to rotate, it will drive the stirring frame 212 to rotate. When the stirring frame 212 rotates, it will drive the fixed plate 214 to move in a circular motion together. At this time, the fixed plate 214 will drive the stirring rod two 216 to move along the same trajectory. At this time, the small gear 215 connected to the stirring rod two 216 will rub against the toothed ring 211. At this time, the toothed ring 211 will drive the stirring rod two 216 to rotate. When the sleeve rod 207 rotates, it will drive the stirring rod 213 to rotate together. At this time, the stirring frame 212, the stirring rod two 216 and the stirring rod 213 cooperate with each other to uniformly stir the composite flame retardant solution, making the crystallization of the composite flame retardant solution more sufficient. When the crystallization is completed, open the discharge pipe 217. Then, the composite flame retardant solution in the cooling crystallization tank 201 will fall downward. When it falls on the filter plate 310, the mother liquor will fall into the separation tank 301 through the holes on the filter plate 310, while the crystals will stay on the filter plate 310. At this time, start the second motor 303. When the second motor 303 starts to operate, it will drive the camshaft 304 to rotate. When the camshaft 304 rotates, it will drive the pulley 305 to rotate. At this time, the pulley 305 will drive the belt pulley 307 to rotate through the belt 306. When the belt pulley 307 starts to rotate, it will drive another camshaft 304 to rotate. When the two camshafts 304 start to rotate simultaneously, the cams fixed on their surfaces will push the filter plate 310 upward. When the filter plate 310 moves upward, it will slide on the sliding shaft 309 and squeeze the spring 311 when it touches the spring 311. When the concave and convex end of the cam no longer touches the filter plate 310, the spring 311 will no longer be squeezed. At this time, the spring 311 will rebound. This rebounding force will reset the filter plate 310. Then, the filter plate 310 will be pushed up again, and this cycle can drive the filter plate 310 to slide. At this time, the separation rate of the composite flame retardant solution can be accelerated. When the separation is completed, the staff collects the crystals on the filter plate 310, and then opens the drain pipe 312 to discharge and collect the mother liquor.
