[0025] Example 1: As Figures 1-4 As shown, a desulfurization wastewater crystallization filtration and separation device includes a separation tank 1. A mounting frame 2 is fixedly connected to the inner wall of the separation tank 1. A threaded rod 3 is rotatably connected to the bottom of the mounting frame 2. The threaded rod 3 is driven by a motor, which is fixedly connected to the top of the mounting frame 2, supporting the motor. A limiting rod 4 is fixedly connected to the bottom of the inner wall of the separation tank 1. A threaded sleeve 5 is threadedly connected to the circumferential surface of the threaded rod 3. The limiting rod 4 restricts the rotation of the threaded sleeve 5. Multiple fan-shaped filter screens 6 are rotatably connected to the circumferential surface of the threaded sleeve 5. The circumferential surfaces of the multiple fan-shaped filter screens 6 are rotatably connected to the same annular frame 7. The fan-shaped filter screens 6 can be rotated to open and close. An air-enhancing device 8 for increasing bubbles in the reaction liquid is provided on the circumferential surface of the threaded rod 3. The air-enhancing device 8 includes a fixing plate 81, the side of which is fixedly connected to the circumferential surface of the threaded rod 3. An air bladder is fixedly connected to the side of the fixing plate 81. 82. The airbag 82 has elasticity to blow out bubbles. A movable plate 83 is fixedly connected to the side of the airbag 82, and a connecting plate 84 is fixedly connected to the side of the movable plate 83. An air inlet pipe 85 is fixedly connected to the top of the airbag 82, and gas enters the airbag 82 through the air inlet pipe 85. An L-shaped air outlet pipe 86 is fixedly connected to the bottom of the airbag 82, and a nozzle 87 is fixedly connected to one end of the L-shaped air outlet pipe 86. Multiple nozzles 88 are fixedly connected to the circumference of the nozzle 87, and the gas is sprayed out from the nozzles 88 through the nozzle 87 after passing through the L-shaped air outlet pipe 86. There is a gap between the nozzle 87 and the connecting plate 84, and a gap between the nozzle 87 and the separation barrel 1, so as not to prevent the movement of each component. A semi-circular block is fixed on the side of the connecting plate 84 away from the movable plate 83. Several semi-circular blocks are evenly and equidistantly fixed on the inner wall of the separation barrel 1. The circular surface of the semi-circular block of the separation barrel 1 is located on the movement trajectory of the circular surface of the semi-circular block of the connecting plate 84.

[0026] First, the motor corresponding to threaded rod 3 is started. The rotation of the motor output shaft drives the rotation of threaded rod 3, which in turn drives the rotation of fixed plate 81. The rotation of fixed plate 81 drives the rotation of airbag 82, which in turn drives the rotation of moving plate 83. The rotation of moving plate 83 drives the rotation of connecting plate 84. When the semicircular block of connecting plate 84 moves to the position of the semicircular block of separation barrel 1, the circular surface of the semicircular block of separation barrel 1 pushes the circular surface of the semicircular block of connecting plate 84, causing the connecting plate 84 to move. The movement of connecting plate 84 drives the movement of the moving plate 84. The movement of plate 83 compresses the air bladder 82. When the semicircular surface of the connecting plate 84 no longer pushes the semicircular block of the separation barrel 1, the air bladder 82 resets under its own spring force, generating bubbles. Gas enters the air bladder 82 from the air inlet pipe 85, passes through the L-shaped air outlet pipe 86, and is ejected from the nozzle 88 through the nozzle 87. This increases the gas-liquid interface area of ​​the liquid, promotes the transfer of dissolved oxygen and other reactants, and the rising movement of the bubbles can increase the mixing effect of the liquid, making the reactants more evenly distributed, thereby accelerating the reaction rate, improving the crystallization efficiency, and enhancing the processing effect.

Several semi-circular blocks are evenly and equidistantly fixed on the inner wall of the separation tank 1, and the circular surface of the semi-circular blocks in the separation tank 1 is located on the movement trajectory of the circular surface of the semi-circular blocks on the fixing rod 92.

[0028] First, the corresponding motor of the threaded rod 3 is started, the rotation of the motor output shaft drives the rotation of the threaded rod 3, the rotation of the threaded rod 3 drives the movement of the threaded sleeve 5, the movement of the threaded sleeve 5 drives the movement of the fan-shaped filter screen 6, the movement of the fan-shaped filter screen 6 drives the movement of the annular frame 7, the movement of the annular frame 7 drives the movement of the elastic telescopic rod 91, the movement of the elastic telescopic rod 91 drives the movement of the fixed rod 92, when the semicircular block of the fixed rod 92 moves to the semicircular block position of the separation barrel 1, the semicircular block of the fixed rod 92 is pushed by the semicircular block of the separation barrel 1 to drive the movement of the fixed rod 92, the movement of the fixed rod 92 drives the movement of the knocking hammer 93 away from the fan-shaped filter screen 6, when the semicircular block of the fixed rod 92 no longer pushes the semicircular block of the separation barrel 1, the elastic telescopic rod 91 is reset under the action of its own spring force and drives the fixed rod 92 to reset and move, the fixed rod 92 resets and moves to drive the knocking hammer 93 to reset and move to knock the fan-shaped filter screen 6, accelerate the settling speed of the flocculation, and improve the efficiency of the desulfurization wastewater crystallization separation.
