[0023] Please see Figure 1-3A low-temperature vacuum distillation treatment device for wastewater includes a distillation tank 100. Heating wires are installed inside the distillation tank 100 to assist in heating the raw materials. Two sets of vacuum circulating water pumps 110 are fixedly installed on the upper side of the distillation tank 100. A feed pipe 120 is fixedly connected to the lower side of the vacuum circulating water pumps 110. A filter pipe 130 is rotatably connected to the lower side of the feed pipe 120. A discharge pipe 140 is rotatably connected to the lower side of the filter pipe 130. The lower side of the discharge pipe 140 is fixedly connected to the distillation tank 100. A steam outlet pipe 300 is fixedly connected to the upper side of the distillation tank 100 and is connected to other cooling devices. The lower side of the distillation tank 100 is conical. A solenoid valve 141 is installed on the lower side of the discharge pipe 140. A drain pipe 400 is fixedly connected to the side of the distillation tank 100, and a vacuum pump 500 is connected to the right side of the tank. During operation, the distillation tank 100 is in a low-pressure vacuum state. External raw materials enter the distillation tank 100 through the vacuum circulating water pump 110, and then are filtered in the filter tube 130. Particles and other impurities in the raw materials remain in the filter tube 130 and are discharged through the feed pipe 140. The filtered raw materials are then evaporated in the distillation tank 100, and the remaining raw materials are discharged through the drain pipe 400. The filter tube 130 enables the device to perform filtration and collect the filtered impurities, allowing for rapid vacuum processing, reducing the cleaning frequency of the device, and increasing the evaporation speed of the raw materials. A rotating tube 200 is rotatably connected to the upper side wall of the distillation tank 100. A first toothed ring 210 is fixedly connected to the inner wall of the rotating tube 200. First cleaning brushes 220 are fixedly connected to both sides of the first toothed ring 210. Two sets of first rotating rods 230 are rotatably connected to the upper side of the distillation tank 100. A first gear 240 is fixedly connected to the lower side of the first rotating rod 230. The first toothed ring 210 meshes with the first gear 240. A motor 250 is fixedly installed on the upper side of the distillation tank 100. The transmission end of the motor 250 is fixedly connected to the left first rotating rod 230. When the motor 250 is started, the left first rotating rod 230 is rotated, which in turn rotates the first toothed ring 210, which in turn rotates the first toothed ring 220. The rotation of ring 210 drives the rotation of rotating tube 200, which in turn drives the rotation of first cleaning brush 220. The first cleaning brush 220 cleans the inner wall of the distillation tank 100, thereby removing residual impurities, salts, and organic matter in conjunction with the wastewater feedstock. This improves the heating efficiency of the electric heating wire inside the distillation tank 100. The discharged wastewater needs to be collected and processed by other more sophisticated equipment. By coordinating rotating tube 200, first toothed ring 210, first cleaning brush 220, first rotating rod 230, first gear 240, and motor 250, the inner wall of the distillation tank 100 can be cleaned, and residual impurities, salts, and organic matter can be removed in conjunction with the wastewater feedstock.This device achieves higher efficiency and faster processing frequency during prolonged and continuous raw material processing. A second gear ring 260 is fixedly connected to the lower side of the rotating tube 200, and a second gear 131 is fixedly connected to the outer side of the filter tube 130. The second gear 131 meshes with the second gear ring 260. Rotation of the rotating tube 200 drives the second gear ring 260 to rotate, which in turn drives the second gear 131 to rotate, which in turn drives the filter tube 130 to rotate. The rotation of the filter tube 130 allows the first cleaning brush 220 to clean the inner wall of the distillation tank 100 while also assisting in cleaning the outer side of the filter tube 130. This is achieved by configuring the second gear 131 and the second gear ring 260. Ring 260 allows the first cleaning brush 220 to assist in cleaning the outer side of the filter tube 130 while cleaning the inner wall of the distillation tank 100, improving the efficiency of the device and thus increasing the filtration speed and efficiency of the subsequent filter tube 130. A second rotating rod 160 is rotatably connected to the upper and lower side walls of the distillation tank 100. Second cleaning brushes 161 are fixedly connected to both the upper and lower sides of the second rotating rod 160. A third gear 162 is fixedly connected to the outer side of the second rotating rod 160. The second gear 131 meshes with the third gear 162. Rotation of the second gear 131 drives the third gear 162 to rotate, which in turn drives the second rotating rod 160 to rotate. The rotation of gear 60 drives the second cleaning brush 161 to rotate, which cleans the upper and lower side walls of the distillation tank 100. This, combined with the wastewater feedstock, removes residual impurities, salts, and organic matter, improving the heating efficiency of the electric heating wire inside the distillation tank 100. The discharged wastewater needs to be collected and treated by other more sophisticated processing equipment. The coordinated operation of the second gear 131, third gear 162, second rotating rod 160, and second cleaning brush 161 effectively cleans the upper and lower side walls of the distillation tank 100, removing residual impurities, salts, and organic matter, and improving the heating efficiency of the electric heating wire inside the distillation tank 100. For continuous long-term raw material processing, higher efficiency and faster frequency are achieved. A third cleaning brush 121 is fixedly connected inside the feed pipe 120, located inside the filter pipe 130. By installing the third cleaning brush 121, residue is discharged from the filter pipe 130. When the filter pipe 130 rotates, the third cleaning brush 121 cleans the inside of the filter pipe 130, thereby improving the filtration speed and efficiency of subsequent filter pipes 130. A slag discharge trough is provided on the lower side of the discharge pipe 140, and a screw cap 142 is connected to the lower side of the discharge pipe 140. The screw cap 142 facilitates manual cleaning of the inside of the filter pipe 130 by operators, improving the stability of the device.
