Detailed implementation manners

[0025] To make the above objects, features and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific implementation manners of the present invention in conjunction with the drawings of the specification.

[0026] Referring to Figure 1-6 , which is an embodiment of the present invention, a wastewater treatment and recycling device is provided. This wastewater treatment and recycling device includes a processing cylinder 1 and a feeding cylinder 2. The feeding cylinder 2 is located above the processing cylinder 1. The outer ring surface of the feeding cylinder 2 is fixed to the outer ring surface of the processing cylinder 1. The lower end of the processing cylinder 1 is a downwardly protruding circular tubular structure, and the lower end of the processing cylinder 1 is conical, effectively preventing water from remaining at the bottom during drainage.

[0027] The bottom surface of the feeding cylinder 2 is rotatably inserted with a rotating disk 10. The upper end of the treatment cylinder 1 is rotatably inserted with a top cover 3. A fixed shaft 4 rotatably penetrates the upper surface of the top cover 3 coaxially. One end of the fixed shaft 4 located inside the treatment cylinder 1 is rotatably sleeved with a plurality of flat plates 5. The fixed shaft 4 is perpendicular to the upper surfaces of the flat plates 5. The plurality of flat plates 5 are circumferentially arrayed around the axis of the fixed shaft 4. Two disks 8 rotatably penetrate the upper surfaces of the flat plates 5.

[0028] The upper surface of the disk 8 is fixedly penetrated with a through-hole discharge column 6. A sandwich floating column 7 is slidably inserted inside the through-hole discharge column 6. The outer ring surface of the through-hole discharge column 6 is a plurality of outwardly protruding plate-like structures. The outer ring surface of the sandwich floating column 7 is a plurality of outwardly protruding plate-like structures adapted to the inside of the through-hole discharge column 6, increasing the discharge area of the through-hole discharge column 6 and at the same time increasing the water stirring effect when the through-hole discharge column 6 rotates. A sandwich is provided inside the sandwich floating column 7 to reduce the weight of the sandwich floating column 7 and increase the buoyancy received by the sandwich floating column 7. The axial part of the sandwich floating column 7 is a circular hole-like structure that is not communicated with the sandwich and is vertically penetrated. A through-feed pipe 9 is slidably inserted inside the circular hole-like structure of the sandwich floating column 7. The upper end of the through-feed pipe 9 rotatably penetrates the bottom surface of the rotating disk 10.

[0029] The upper end of the fixed shaft 4 rotatably penetrates the bottom surface of the rotating disk 10. An external gear ring 17 is coaxially fixed to the bottom surface of the rotating disk 10. The external gear ring 17 is coaxially arranged with the fixed shaft 4. A motor 18 is fixed to the outer ring surface of the feeding cylinder 2. The output end of the motor 18 is fixed with a driving gear 19. The driving gear 19 meshes with the outer ring surface of the external gear ring 17. The meshing of the driving gear 19 and the external gear ring 17 can drive the rotating disk 10 to rotate. The upper end of the fixed shaft 4 is fixed to the inside of the feeding cylinder 2. A gear disk 11 is slidably sleeved on the upper end of the sandwich floating column 7. The top cover 3 is rotatably sleeved on the outer surface of the gear disk 11. An internal gear ring 15 and a linkage gear 16 are provided above the top cover 3. The linkage gear 16, the internal gear ring 15 and the fixed shaft 4 are coaxially arranged. The outer ring surface of the internal gear ring 15 is fixed to the outer ring surface of the treatment cylinder 1. The linkage gear 16 is fixedly sleeved on the outer surface of the fixed shaft 4. The two gear disks 11 above the same flat plate 5 are respectively meshed with the inner ring surface of the internal gear ring 15 and the outer ring surface of the linkage gear 16. When the top cover 3 rotates, the two gear disks 11 above the same flat plate 5 are respectively meshed with the linkage gear 16 and the internal gear ring 15, driving the sandwich floating column 7 and the through-hole discharge column 6 to rotate around the axis of the connected gear disk 11.

[0030] A filter disk 12 is slidably inserted inside the treatment cylinder 1. The filter disk 12 is located below the through-hole discharge column 6. The shape of the filter disk 12 is a cone adapted to the lower end of the treatment cylinder 1, so that the upper sediment has a tendency to flow towards the axis. The axial part of the filter disk 12 is a downwardly protruding circular tubular structure. The circular tubular structure of the filter disk 12 is located inside the circular tubular structure of the treatment cylinder 1. The lower end of the circular tubular structure of the filter disk 12 is located below the lower end of the circular tubular structure of the treatment cylinder 1.

[0031] A detachable outer plug 13 is installed at the lower end of the cylindrical structure of the treatment cylinder 1. An inner plug 14 is arranged inside the outer plug 13. The inner plug 14 is detachably installed at the lower end of the cylindrical structure of the filter disc 12. A detachable outer plug 13 is installed at the lower end of the cylindrical structure of the treatment cylinder 1. An inner plug 14 is arranged inside the outer plug 13. The inner plug 14 is detachably installed at the lower end of the cylindrical structure of the filter disc 12. Unscrewing the outer plug 13 can first drain the water in the treatment cylinder 1. After the water in the treatment cylinder 1 is drained, then removing the inner plug 14 can discharge the sediment above the filter disc 12, discharging the water and the sediment separately.

[0032] During use, according to the different heights of the water volume, the sandwich floating column 7 moves upward by different distances under the buoyancy of water. The part of the sandwich floating column 7 that fits the through-hole discharging column 6 is blocked. The feeding cylinder 2 adds flocculant to the space below the sandwich floating column 7 inside the through-hole discharging column 6 through the feeding pipe 9 and the circular hole-shaped structure inside the sandwich floating column 7, so that only the part of the through-hole discharging column 6 located underwater can discharge the flocculant. When the motor 18 drives the rotating disc 10 to rotate through the driving gear 19 meshing with the outer tooth ring 17, the rotating disc 10 drives the top cover 3 to rotate synchronously through the feeding pipe 9. The top cover 3 drives the tooth disc 11 to mesh with the inner tooth ring 15 and the linkage gear 16 respectively, so that the through-hole discharging column 6 rotates around the axis of the upper tooth disc 11 and rotates around the fixed shaft 4 at the same time. When the through-hole discharging column 6 rotates, it can stir the mixture of water and flocculant inside, and at the same time, when the through-hole discharging column 6 rotates, it applies a centrifugal force to the flocculant, increasing the discharging distance of the flocculant from the through-hole discharging column 6. After the filtration is completed, unscrewing the outer plug 13 can first drain the water in the treatment cylinder 1. After the water in the treatment cylinder 1 is drained, removing the inner plug 14 can discharge the sediment above the filter disc 12.
