[0028] Please see Figures 1 to 7 In this embodiment of the invention, a solar-powered evaporation and desalination purification device for high-salt wastewater includes an inlet 1, one end of which is fixedly connected to an evaporation tank 2. An outlet 5 is fixedly connected to the outer wall of the evaporation tank 2, and a condenser 6 is fixedly connected to one end of the outlet 5. The evaporation tank 2 consists of an upper shell 3 and a lower shell 4. The inlet 1 is connected to the bottom of the lower shell 4, and the outlet 5 is connected to the outer wall of the upper shell 3. The liquid entering the evaporation tank 2 is evaporated through an evaporation mechanism 7. The evaporation mechanism 7 includes a concentrator 701, which is located at the top of the upper shell 3. A mounting bracket 702 is fixedly connected to the inner wall of the upper shell 3, and a heating plate 703 is installed at the bottom of the mounting bracket 702. The heating plate 703 is connected to an external solar panel via a wire. A filter plate 704 is installed in the inner cavity of the lower shell 4. The upper shell 3 and the lower shell 4 are fixedly connected by an installation mechanism 8, and the top of the upper shell 3 is shielded by a shielding mechanism 9.

[0029] In this embodiment: the feed inlet 1 delivers wastewater and hot air into the evaporator 2. When the wastewater passes through the filter plate 704, the filter plate 704 filters out large particulate impurities in the wastewater. The concentrator 701 focuses sunlight to contact the wastewater, while the heating plate 703 heats the wastewater, causing it to evaporate. The water vapor generated by evaporation enters the condenser 6 through the air outlet 5 for condensation. The water generated by condensation is collected and utilized, facilitating the evaporation, desalination, and purification of high-salt wastewater.

[0030] Please refer to this carefully. Figures 1 to 4 The mounting mechanism 8 includes a first docking block 801, which is fixedly connected to the outer walls of both sides of the upper shell 3. Second docking blocks 802 are fixedly connected to the outer walls of both sides of the lower shell 4. A connecting groove 803 is formed at the bottom of the first docking block 801, and a fixing groove 804 is formed on the inner wall of the connecting groove 803. A connecting block 805 is fixedly connected to the top of the second docking block 802. A fixing block 806 is slidably connected inside the second docking block 802 and the connecting block 805. The fixing block 806 extends out of the connecting block 805. A first spring 807 connects the fixing block 806 and the connecting block 805. A pushing block 808 is slidably connected inside the second docking block 802, located on one side of the fixing block 806. One end of the docking block 802 is rotatably connected to a rotating block 810, and one end of the rotating block 810 is fixedly connected to a lead screw 809. The lead screw 809 extends into the inner cavity of the pushing block 808. The mounting mechanism 8 also includes a support plate 811, which is fixedly connected to the inner cavity of the lower shell 4. The top of the support plate 811 is provided with a placement groove 812 for placing the filter plate 704. The bottom end of the pushing block 808 is fixedly connected to a displacement frame 813. The inside of the lower shell 4 is rotatably connected to the bottom end of the displacement frame 813. The inside of the lower shell 4 is slidably connected to the bottom end of the first spur gear 814. The positioning block 815 extends into the inner cavity of the lower shell 4 and is located at the top of the support plate 811.

[0031] In this embodiment: when docking the upper shell 3 and the lower shell 4, the connecting block 805 is inserted into the connecting groove 803 until the fixing block 806 is engaged into the fixing groove 804 by the elastic force of the first spring 807, thereby fixing the first docking block 801 and the second docking block 802, and thus fixing the upper shell 3 and the lower shell 4.

[0032] When separating the upper shell 3 and the lower shell 4, rotate the rotating block 810. The rotation of the rotating block 810 drives the lead screw 809 to rotate. The rotation of the lead screw 809 drives the pushing block 808 to move. The displacement of the pushing block 808 pushes the fixed block 806 to move. The fixed block 806 moves out of the fixed groove 804, thus canceling the fixation between the upper shell 3 and the lower shell 4.

[0033] When the lower shell 4 is removed, the pushing block 808 presses against the fixing block 806. At this time, the displacement of the pushing block 808 causes the displacement frame 813 to move. The displacement of the displacement frame 813 causes the first spur gear 814 to rotate. The rotation of the first spur gear 814 causes the positioning block 815 to move. The positioning block 815 moves and separates from the filter plate 704. At this time, the filter plate 704 can be removed from the placement groove 812, replaced and cleaned. Afterwards, the filter plate 704 is placed back into the placement groove 812. After the lower shell 4 is installed, rotating the rotating block 810 drives the pushing block 808 to reset. The displacement of the push block 808 causes the displacement frame 813 to move, which in turn causes the first spur gear 814 to rotate. The rotation of the first spur gear 814 causes the positioning block 815 to move, and the positioning block 815 moves to contact the top of the filter plate 704, fixing the filter plate 704 in the placement groove 812. This automatically fixes the filter plate 704, facilitating quick connection and disassembly of the upper shell 3 and the lower shell 4, and making it easy to disassemble and clean the lower shell 4. When the lower shell 4 is removed, the fixation of the filter plate 704 is automatically released, facilitating the cleaning operation of the filter plate 704.

[0034] Please refer to this carefully. Figures 5 to 7 The shielding mechanism 9 includes a baffle 901, which is disposed at the top of the upper shell 3. A movable block 902 is fixedly connected to the bottom of the baffle 901. A movable seat 903 is fixedly connected to the top of the upper shell 3. The movable block 902 is slidably connected to the inner wall of the movable seat 903. A second spur gear 904 extending into the inner cavity of the movable seat 903 is rotatably connected inside the movable seat 903. A connecting shaft 905 is fixedly connected to the bottom of the second spur gear 904. A first bevel gear 906 is fixedly connected to the bottom of the connecting shaft 905. A second bevel gear 907 is rotatably connected to the outer wall of the first bevel gear 906 inside the upper shell 3. A third spur gear 908 is fixedly connected to one end of the second bevel gear 907. A pressing rod 909 is slidably connected to the outer wall of the third spur gear 908 inside the upper shell 3. A second spring 910 is connected between the top of the pressing rod 909 and the upper shell 3.

[0035] In this embodiment: when the upper shell 3 and the lower shell 4 are connected, the lower shell 4 contacts the extrusion rod 909, pushing the extrusion rod 909 to move and compress the second spring 910. The displacement of the extrusion rod 909 drives the third spur gear 908 to rotate. The rotation of the third spur gear 908 drives the second bevel gear 907 to rotate. The rotation of the second bevel gear 907 drives the first bevel gear 906 to rotate. The rotation of the first bevel gear 906 drives the connecting shaft 905 to rotate. The rotation of the connecting shaft 905 drives the second spur gear 904 to rotate. The rotation of the second spur gear 904 drives the movable block 902 to slide in the movable seat 903. The displacement of the movable block 902 drives the baffle 901 to move. The baffle 901 moves away from above the condenser lens 701 to avoid obstructing the condenser lens 701.

[0036] When the upper shell 3 and the lower shell 4 are separated, the compression rod 909 is reset by the elastic force of the second spring 910, thereby driving the baffle 901 to move to the top of the condenser lens 701, so as to prevent the light gathered by the condenser lens 701 from directly contacting the heating plate 703 after the lower shell 4 is disassembled, thus preventing damage to the heating plate 703.

[0037] Please refer to this carefully. Figures 1 to 4 The inner wall of the connecting groove 803 is in contact with the outer wall of the connecting block 805, and the inner wall of the fixing groove 804 is in contact with the outer wall of one end of the fixing block 806.

[0038] In this embodiment: the connecting block 805 is inserted into the connecting groove 803 until the fixing block 806 is engaged into the fixing groove 804 by the elastic force of the first spring 807, thereby fixing the first docking block 801 and the second docking block 802, and thus fixing the upper shell 3 and the lower shell 4.

[0039] Please refer to this carefully. Figures 1 to 4 One end of the push block 808 has a threaded hole that matches the lead screw 809.

[0040] In this embodiment: the rotating block 810 rotates to drive the lead screw 809 to rotate, the lead screw 809 rotates to drive the push block 808 to move, the push block 808 moves to drive the fixed block 806 to move, the fixed block 806 moves out of the fixed groove 804, and the fixation between the upper shell 3 and the lower shell 4 is canceled.

[0041] Please refer to this carefully. Figures 1 to 4 The inner wall of the placement groove 812 is in contact with the outer wall of the filter plate 704. The bottom end of the displacement frame 813 and the top end of the positioning block 815 are both provided with toothed grooves, which mesh with the first spur gear 814.

[0042] In this embodiment: when the lower shell 4 is removed, the pushing block 808 presses the fixing block 806. At this time, the displacement of the pushing block 808 causes the displacement frame 813 to move. The displacement of the displacement frame 813 causes the first spur gear 814 to rotate. The rotation of the first spur gear 814 causes the positioning block 815 to move. The positioning block 815 moves and separates from the filter plate 704. At this time, the filter plate 704 can be taken out from the placement groove 812.

[0043] Please refer to this carefully. Figures 5 to 7 The outer wall of the extrusion rod 909 is provided with a first gear tooth, which meshes with the third spur gear 908.

[0044] In this embodiment: when the upper shell 3 and the lower shell 4 are connected, the lower shell 4 contacts the extrusion rod 909, pushing the extrusion rod 909 to move and extruding the second spring 910. The displacement of the extrusion rod 909 drives the third spur gear 908 to rotate.
