[0023] The upper end of the concentrator 3 is fixedly connected to a fixed column 67, and the outer surface of the fixed column 67 is rotatably connected to an outer scraper bar 68. The outer surface of the scraper plate 61 is fixedly connected to a No. 1 magnetic strip 615, and the inner side of the outer scraper bar 68 is fixedly connected to a No. 2 magnetic strip 616, and the No. 2 magnetic strip 616 and the No. 1 magnetic strip 615 are magnetically connected; the outer surface of the support part 2 is fixedly connected to a drain pipe 7 corresponding to the protruding ring 612, the outer surface of the wastewater tank 1 is fixedly connected to an inlet pipe 8 for entering wastewater, the lower end of the wastewater tank 1 is fixedly connected to a discharge pipe 9 for discharging wastewater, and the lower end of the wastewater tank 1 is fixedly connected to one end of the central axis 4 with a reduction motor 10, the reduction motor 10 is used to drive the central axis 4 to rotate, and the reduction motor 10 is rotatably connected to the wastewater tank 1 and the concentrator 3 through bearings.

[0024] The scraper plate 61 is used to scrape the distilled water on the inner wall of the condenser 3. The locking plate 63 matches the slot 65. The slider 617 is fixedly connected to the scraper plate 61. The locking plate 63 is connected and separated in the slot 65 on the surface of the connecting plate 64 by extending or contracting the transverse electric cylinder 62. The scraper plate 61 is rotated by moving the connecting plate 64 by the locking plate 63. The guide groove 69 is used to collect the distilled water scraped off by the scraper plate 61. The number of the inner extension frame 610 and the roller 611 are both in several groups. The roller 611 is a horizontal "I"-shaped structure, and the "I"-shaped opening of the roller 611 just corresponds to the position of the protruding ring 612. The inner lower edge of the condenser 3 and the outer lower edge of the scraper plate 61 just match the opening of the collecting groove 613. The roller 611 and the protruding ring 612 are in a rolling connection.

[0025] The magnetic force between the second magnetic strip 616 and the first magnetic strip 615 enables the outer scraping strip 68 to rotate while the scraping plate 61 rotates. The fixed column 67 is located at the top of the condenser 3. The outer scraping strip 68 is rotatably connected to the fixed column 67 through a bearing. The outer scraping strip 68 is used to scrape water stains or stains on the surface of the condenser 3.

[0026] In this embodiment, during use, the water droplets generated by distillation on the inner wall of the condenser 3 can be scraped off and collected, and the outer surface of the condenser 3 can be cleaned or the raindrops on its surface can be cleared, thereby maintaining the focusing performance of the condenser 3.

[0027] In summary, the operating principles of the present invention are as follows: During use, sunlight is incident on the interior of the wastewater tank 1 from the condenser 3, thereby irradiating the high-salt wastewater inside the wastewater tank 1. At this time, the reduction motor 10 can be operated, and the reduction motor 10 drives the central shaft 4 to rotate slowly. The rotation of the central shaft 4 can drive the protruding plate 51 to rotate, and the rotation of the protruding plate 51 drives the clamping plate 52 to rotate. The clamping plate 52 drives the heat conducting member 53 and the stirring plate 54 to rotate. The high-salt wastewater is stirred by the rotation of the stirring plate 54, so that the high-salt wastewater is heated more evenly, thereby achieving a better distillation effect and avoiding uneven temperature in different areas of the wastewater irradiated by light and heat. At the same time, during the rotation of the heat conducting member 53, the guide wheel 512 pushes the tilting ring 59, causing relative rolling between the guide wheel 512 and the tilting ring 59. At this time, since the heights of the tilting ring 59 are different at different positions, gravity allows the guide wheel 512 to push the tilting ring 59 and the heat conducting member 53 up and down. During this movement, the protruding plate 51 moves up and down on the inner side of the clamping plate 52, thereby adjusting the stirring range of the heat conducting member 53 and the stirring plate 54, thereby achieving a uniform distillation effect. During the above process, the height of the guide wheel 512 can be adjusted by retracting and pushing the vertical electric cylinder 510, thereby adjusting the maximum distance of the up and down movement of the heat conducting member 53. It should be noted that the maximum range should not exceed the maximum height of the clamping plate 52, that is, the protruding plate 51 is never separated from the clamping plate 52. During the stirring process used above, through the rotation and stirring of the stirring plate 54, the up and down movement of the stirring plate 54 always drives the protruding plate 56 to move up and down, and the up and down movement of the protruding plate 56 will not drive the sliding plate 58 to move up and down. The protruding plate 56 follows the horizontal rotation of the stirring plate 54 to drive the sliding plate 58 to rotate, so that the sliding plate 58 scrapes off the stains on the surface of the reflector 50, thereby maintaining its light reflection effect, and thus achieving a better photothermal effect.

[0028] When the central shaft 4 drives the horizontal electric cylinder 63 to rotate, the clamping plate 63 is inserted into the inner part of the clamping groove 65, and the clamping plate 63 and the connecting plate 64 are connected. When the central shaft 4 drives the horizontal electric cylinder 62 to rotate, the clamping plate 63 drives the connecting plate 64 to rotate together. The rotation of the connecting plate 64 drives the scraper plate 61 to rotate accordingly. The scraper plate 61 scrapes the distilled water on the inner wall surface of the condenser 3. Under the action of gravity, the water droplets gather into a large number and flow into the interior of the guide member 614 under the action of the guide groove 69. The water flows directly into the interior of the collecting groove 613 through the guide member 614 and is then discharged through the drain pipe 7. During the above-mentioned use, the stability of the rotation of the upper end of the scraper plate 61 is maintained by the annular slide rail 66 and the slider 617. At the same time, the stability of the rotation of the lower end of the scraper plate 61 can be maintained by the inner extension frame 610, the roller 611 and the protruding ring 612. In the process of the rotation of the scraper plate 61, under the magnetic action of the No. 1 magnetic strip 615 and the No. 2 magnetic strip 616, the outer scraper strip 68 can be driven to rotate with it. Through the scraping of the outer scraper strip 68, the outer surface of the focus cover 3 can be cleaned, thereby making the focusing effect of the focus cover 3 better, and will not aggravate the light corrosion caused by the formation of small water droplets on the inner and outer sides of the focus cover 3, and the use effect is better.

[0029] During the entire use process, the liquid inlet pipe 8 is used to inject high-salt wastewater, and the discharge pipe 9 is used to discharge the distilled wastewater.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
