Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. Embodiment 1

[0023] Please refer to Figures 1-4 A device for recovering high-salinity wastewater, comprising a cylinder 1, the top of the cylinder 1 is fixedly connected with a liquid inlet pipe 2, the bottom of the cylinder 1 is fixedly connected with a discharge pipe 11, the inside of the bottom end of the cylinder 1 is fixedly installed with a heating plate 12, the bottom of the discharge pipe 11 is screwed with a pipe cover, the upper part of the inner cavity of the cylinder 1 is fixedly connected with a filter screen 3, the filter screen 3 is provided with a cleaning assembly inside, and a discharge assembly is arranged below the filter screen 3; the cleaning assembly comprises an annular plate 31 rotatably arranged on the top of the annular plate 31, the inner side of the annular plate 31 is fixedly connected with an arc plate 32, a plurality of tooth 33 are uniformly fixedly connected to the outer part of the annular plate 31, a first motor 34 is fixedly installed outside the cylinder 1, the output end of the first motor 34 is fixedly connected with a gear 35, and the gear 35 is meshedly connected with the tooth 33.

[0024] Specifically, the filter screen 3 is arranged in a circular arc shape, the lower surface of the arc plate 32 abuts against the upper surface of the filter screen 3, the filter screen 3 is provided with a discharge hole 36, the discharge hole 36 is in communication with a connecting pipe 41, and the arc plate 32 is located above the discharge hole 36; the discharge assembly comprises a connecting pipe 41 fixedly connected to the bottom of the filter screen 3, the end of the connecting pipe 41 extends to the outside of the cylinder 1 and is fixedly connected with a collection frame 42, and the top of the collection frame 42 is hingedly connected with a cover plate 43; the bottom of the collection frame 42 is fixedly connected with a liquid discharge pipe 44, the other end of the liquid discharge pipe 44 is in communication with the cylinder 1, and a one-way valve 45 is installed on the liquid discharge pipe 44.

[0025] Furthermore, wastewater enters the cylinder 1 through the top inlet pipe 2 and undergoes preliminary filtration through the filter screen 3. To prevent clogging of the filter screen 3, a cleaning component is installed inside the device. After all the wastewater has been poured into the cylinder 1, the first motor 34 can be started. The gear 35 connected to its output end will drive the teeth 33 on the outside of the annular plate 31 to rotate, thereby causing the annular plate 31 and the arc-shaped plate 32 on it to rotate around the filter screen 3. Since the lower surface of the arc-shaped plate 32 abuts against the upper surface of the filter screen 3, it can effectively clean the impurities accumulated on the filter screen 3. Because the filter screen 3 is set in an arc shape, the impurities will slide down to the bottom of the filter screen 3 under the action of gravity during the cleaning process of the arc-shaped plate 32. As the filtration process proceeds, the trapped impurities or concentrates enter the connecting pipe 41 through the discharge hole 36 and are finally collected in the external collection frame 42.

These concentrated substances can be discharged by opening the cover at the bottom of the discharge pipe 11. Example 2

[0026] Please see Figure 2 , Figure 3 and Figure 5 This embodiment provides a technical solution based on embodiment one: a scraping assembly is provided inside the cylinder 1. The scraping assembly includes a second motor 51 fixedly installed on the cylinder 1. A rotating rod 52 is fixedly connected to the output end of the second motor 51. The rotating rod 52 extends through the filter screen 3 to the lower part of the cylinder 1 and is rotatably connected to the filter screen 3. A connecting rod 53 is fixedly connected to one side of the lower part of the rotating rod 52. The connecting rod 53 is fixedly connected to the scraper 54.

A fixing ring 23 is screwed together on the outside of the filter element 21 and the liquid inlet pipe 2.

[0027] Steam is generated when the wastewater is heated, and the water in the high-salt wastewater evaporates, and the particles gradually precipitate inside and adhere to the cylinder 1. By starting the second motor 51, the second motor 51 drives the rotating rod 52 to rotate, and the connecting rod 53 and the scraper 54 connected to the rotating rod 52 move accordingly. The scraper 54 slides tightly against the inner wall of the cylinder 1, which can effectively remove the residues adhering to the inner wall and ensure the long-term stable operation of the equipment. When treating wastewater, first remove the filter 21 to pour in the wastewater, and when entering the evaporation stage, reinstall the filter 21 into the liquid inlet pipe 2, and firmly fix the filter 21 and the liquid inlet pipe 2 through the fixing ring 23. The fixing ring 23 is used to ensure the stable installation of the filter 21 and the activated carbon filter screen 22, so that during the discharge of steam through the liquid inlet pipe 2, purification treatment is carried out through the activated carbon filter screen 22 to prevent environmental pollution.

[0028] Working principle: During the use of the device, wastewater enters the cylinder 1 through the liquid inlet pipe 2 at the top, and is first filtered by the filter screen 3. The filtered wastewater enters the bottom of the cylinder 1, and when all the wastewater is poured into the cylinder 1, the first motor 34 is started, and the gear 35 connected to the output end of the first motor 34 drives the teeth 33 on the outer side of the annular plate 31 to rotate, thereby rotating the annular plate 31 and the arc-shaped plate 32 thereon around the filter screen 3, thereby effectively cleaning the impurities accumulated on the filter screen 3. Since the filter screen 3 is arranged in a circular arc shape, the impurities will slide down to the bottom of the filter screen 3 under the action of gravity during the cleaning process of the arc-shaped plate 32. As the filtration process proceeds, the trapped impurities or concentrates enter the connecting pipe 41 through the discharge hole 36 and are finally collected in the external collection frame 42. By opening the one-way valve 45, the wastewater brought by the impurities can be discharged into the cylinder 1 again through the liquid discharge pipe 44. When entering the evaporation stage, the filter 21 is installed into the liquid inlet pipe 2, and the filter 21 and the liquid inlet pipe 2 are fixed together through the fixing ring 23, and the high-salt wastewater at the bottom of the cylinder 1 is heated and evaporated by starting the heating plate 12, so that salt crystals are evaporated. By starting the second motor 51, the second motor 51 drives the rotating rod 52 to rotate, and the connecting rod 53 and the scraper 54 connected to the rotating rod 52 move accordingly. The scraper 54 slides tightly against the inner wall of the cylinder 1, which can effectively remove the residues adhering to the inner wall and ensure the long-term stable operation of the equipment. When treating wastewater, first remove the filter 21 to pour in the wastewater, and when entering the evaporation stage, reinstall the filter 21 into the liquid inlet pipe 2, and firmly fix the filter 21 and the liquid inlet pipe 2 through the fixing ring 23. The fixing ring 23 is used to ensure the stable installation of the filter 21 and the activated carbon filter screen 22, so that during the discharge of steam through the liquid inlet pipe 2, purification treatment is carried out through the activated carbon filter screen 22 to prevent environmental pollution.
