A cleaning plate 12 is fixed to the end of the longitudinal moving tube 21 away from the circular rotating shaft 11, and an adjustment component for adjusting the distance between the two cleaning plates 12 is provided inside the circular rotating shaft 11. Through the operation of the driving motor 7, the circular rotating shaft 11 can be rotated, and the rotation of the circular rotating shaft 11 enables the longitudinal light rod 20, the longitudinal moving tube 21 and the cleaning plate 12 to rotate, thereby increasing the disturbance of the liquid inside the crystallization collection tank 1 to improve the crystallization efficiency of the saline water inside the crystallization collection tank 1.

[0028] The adjusting assembly includes a cylinder 17, a cylinder 17 is installed inside the circular rotating shaft 11, and a transverse moving plate 18 is fixed to the output end of the cylinder 17, and both ends of the transverse moving plate 18 are pin-rotatably connected with an oblique rotating column 19, and the oblique rotating column 19 is close to one end of the longitudinal moving tube 21 and is rotatably connected to the longitudinal moving tube 21 through a pin. Through the operation of the cylinder 17, the transverse moving plate 18 can be moved, and the movement of the transverse moving plate 18 enables the longitudinal moving tube 21 to slide on the outside of the longitudinal polished rod 20 through the oblique rotating column 19, thereby adjusting the distance between the two cleaning plates 12, so that the cleaning plate 12 can fit the inside of the arc filter plate 9, and through the operation of the driving motor 7, the crystals on the inside of the arc filter plate 9 can be cleaned, so as to prevent the crystals on the inside of the arc filter plate 9 from affecting the filtering effect of the arc filter plate 9;

[0029] A circular through hole is provided inside the longitudinal moving tube 21. The longitudinal polished rod 20 and the longitudinal moving tube 21 are slidably connected via the circular through hole. The circular through hole enables the longitudinal moving tube 21 to slide outside the longitudinal polished rod 20, thereby guiding the movement trajectory of the cleaning plate 12.

[0030] In addition, a unloading mechanism for unloading is provided inside the discharge chute 8, and the unloading mechanism includes a transverse circular tube 13. The transverse circular tube 13 is fixed to one end of the discharge chute 8 close to the enthalpy difference compensation expansion purification recovery tank 2. The internal thread of the transverse circular tube 13 is connected to a transverse threaded rod 14. The end of the transverse threaded rod 14 away from the discharge chute 8 is fixed with a handwheel 16. The internal sliding connection of the transverse threaded rod 14 is connected to a transverse sliding column 15. The transverse sliding column 15 is close to one end of the circular storage trough 10 and is fixedly connected to the circular storage trough 10.

[0033] Working principle: When the wastewater utilization equipment of the present technical solution is used, after the continuous drainage containing saline-alkali water enters the crystallization collection tank 1 through the air inlet pipe 3, the enthalpy difference compensation expansion purification recovery tank 2 is set to inject hot water into the interior of the air inlet pipe 3 to increase the problem of the liquid inside the crystallization collection tank 1, so that the temperature of the continuous drainage inside the crystallization collection tank 1 can reach the temperature of evaporation and crystallization, and the crystals can be filtered through the filtration of the arc filter plate 9, and injected into the interior of the enthalpy difference compensation expansion purification recovery tank 2 through the first connecting pipe 5, and the circular rotation is made by the operation of the driving motor 7. The shaft 11 can rotate. The rotation of the circular rotating shaft 11 enables the longitudinal polished rod 20, the longitudinal movable tube 21 and the cleaning plate 12 to rotate, thereby stirring the liquid in the crystallization collection tank 1, thereby improving the efficiency of the salt-alkali water crystallization. The operation of the cylinder 17 enables the transverse movable plate 18 to move. The movement of the transverse movable plate 18 enables the longitudinal movable tube 21 to slide on the outside of the longitudinal polished rod 20 through the oblique rotating column 19, so that the cleaning plate 12 can move toward the direction of the curved filter plate 9, so as to facilitate the cleaning of the crystals inside the curved filter plate 9.

[0034] After the crystals enter the circular storage trough 10 through the feed trough, the handwheel 16 is rotated. The rotation of the handwheel 16 allows the transverse threaded rod 14 to rotate inside the transverse circular tube 13. Through the threaded connection between the transverse threaded rod 14 and the transverse circular tube 13, the transverse sliding column 15 can slide inside the transverse threaded rod 14, and the rotation of the transverse threaded rod 14 allows the transverse sliding column 15 to rotate, thereby allowing the circular storage trough 10 to rotate inside the discharge trough 8, so that the crystals inside the circular storage trough 10 can be discharged.
