[0024] SeeFigure 1 , Figure 2 , Figure 3 and Figure 4 are the schematic structural diagrams of this patent, a filter device for arsenic and fluoride removal in water treatment, including a fixed bracket 2 and a water treatment tank 1. A fixed hoop 3 is assembled inside the fixed bracket 2, and the water treatment tank 1 is assembled within the fixed hoop 3. Through the arrangement of the fixed hoop 3, the water treatment tank 1 is installed inside the fixed bracket 2;

[0025] A filter box 10 is assembled at the bottom end of the water treatment tank 1. A fixed rod 18 is assembled inside the water treatment tank 1. A bearing 19 is assembled at the center of the fixed rod 18. The inner wall of the filter and 10 is provided with internal threads. An exhaust pipe is installed at the lower end of the water treatment tank 1, and external threads are provided on the outer wall of the exhaust pipe. By means of thread fitting, the filter box 10 is installed outside the exhaust pipe, thereby connecting the filter box 10 to the inside of the water treatment tank 1;

[0026] A driven rotating shaft 17 is assembled inside the bearing 19. Stirring rods 18 are assembled on both outer walls of the driven rotating shaft 17. The driven rotating shaft 17 can rotate within the bearing 19, thereby stirring the groundwater inside the water treatment tank 1 through the stirring rods 18;

[0027] A screw conveyor 23 is assembled at the lower end of the driven rotating shaft 17. The screw conveyor 23 is located at the filter box 10, and the screw conveyor 23 can agitate inside the filter box 10;

[0028] A carrier frame 4 is assembled at the top end of the water treatment tank 1, and a feeding mechanism is assembled inside the carrier frame 4;

[0029] The feeding mechanism includes a coagulant feed pipe 5, a coagulant aid feed pipe 6, and a fine sand carrier feed pipe 7, thereby adding a coagulant, a polymer coagulant aid, and a fine sand carrier into the water treatment tank 1 to promote the formation of flocs. Ripeening is carried out through a heating plate arranged inside the water treatment tank 1. High-density alum flowers are formed through slow stirring, and finally enter the filter box 10 to form arsenic and fluoride removal treatment for groundwater.

[0030] A motor base 8 is assembled on the outer wall of the water treatment tank 1. A driving rotating shaft 22 is assembled inside the motor base 8. One end of the driving rotating shaft 22 extends into the water treatment tank 1 and is installed with a driving bevel gear 21. A driven bevel gear 20 is assembled outside the driven rotating shaft 17. The driving bevel gear 21 and the driven bevel gear 20 are meshed with each other. The driving rotating shaft 22 can rotate within the motor base 8, and through the meshing of the driving bevel gear 21 and the driven bevel gear 20, the driven rotating shaft 17 is driven to rotate by the driving rotating shaft 22.

[0031] A servo motor 9 is assembled on the side wall of the motor base 8. The driving rotating shaft 22 is connected to the driving end of the servo motor 9. The driving rotating shaft 22 can be driven to rotate by the servo motor 9.

On both side walls of the wire frame 12, limiting blocks 14 are installed. The limiting blocks 14 are installed in the limiting grooves 13. At the upper end of the filter box 10 and below the filter net 11, a valve 15 is installed. The limiting grooves 13 are arranged on the inner wall of the filter box 10 from top to middle. The wire frame 12 can be stuck in the limiting grooves 13 through the limiting blocks 14 and then installed inside the filter box 10.

The rotating rod of the auger 23 is provided with external threads. Through the thread fit with the screw groove 24, the auger 23 is installed at the lower end of the driven rotating shaft 17.

[0034] Outside the rotating rod of the auger 23, a rubber pad a25 and a rubber pad b27 are sleeved. Between the rubber pad a25 and the rubber pad b27, a rubber block 26 is assembled. The outer diameters of the rubber pad a25 and the rubber pad b27 are larger than the inner diameter in the screw groove 24. Thus, after the auger 23 is installed at the lower end of the driven rotating shaft 17, the gap between the two is sealed.

[0035] When this patent works, during use, first, the auger 23 is installed at the lower end of the driven rotating shaft 17. Then, the filter net 11 is installed inside the filter box 10. Next, the filter box 10 is installed at the lower end of the water treatment tank 1, and the valve 15 is closed. Then, groundwater is added into the water treatment tank 1. The servo motor 9 is started to stir the inside. Through the feeding mechanism, a coagulant, a polymer coagulant aid, and a fine sand carrier are added into the water treatment tank 1 to promote the formation of flocs. Through the heating plate arranged in the water treatment tank 1, ripening is carried out. Through slow stirring, high-density alum flowers are formed. Finally, it enters into the filter box 10 to form the arsenic and fluoride removal treatment of groundwater.
