[0038] Working principle: When it is necessary to use the geothermal tailwater reinjection device, first, the tailwater is poured into the left cavity of the partition 2 inside the box body 1 through the water inlet pipe 30. At this time, the hydraulic cylinder 6 is started. At this time, the hydraulic cylinder 6 drives the rack plate 7 to move on the upper surface of the protective box 3, thereby driving the rack plate 7 to mesh with the spur gear 2 8 and rotate. At this time, the spur gear 2 8 is rotated to mesh with the spur gear 1 5. At this time, the rotation of the spur gear 1 5 drives the stirring rod 4 to stir the tailwater to prevent the sludge in the tailwater from settling. At this time, the tailwater will enter the cavity on the right side of the partition 2 through the opening on the upper side of the partition 2. At this time, the tailwater is filtered through the filter plate 14. When the rack plate 7 moves back and forth At the same time, the cleaning brush 10 on one side of the connecting plate 9 is driven by the rack plate 7 to reciprocate inside the partition 2. At this time, the movement of the cleaning brush 10 can clean the impurities attached to the outer wall of the filter plate 14. The movement of the cleaning brush 10 can prevent the filter plate 14 from being blocked. When the filter plate 14 is used for a long time, the rotating buckle 16 is rotated to separate it from the upper surface of the baffle 15. At this time, the baffle 15 is turned over, and the reaction force of the spring 13 drives the telescopic rod 12 to contract, thereby achieving the effect of driving the filter plate 14 inside the sliding frame 11 to quickly lift the inside of the box body 1. The movement of the sliding frame 11 can achieve the effect of quickly replacing the filter plate 14.

[0039] Secondly, when the filtered tail water enters the cavity on the right side of the partition 2, the effect of the internal filtered water volume can be observed by the scale set on one side of the cavity. At this time, the water flow will enter the outlet pipe 19 through the filter plate 21, and then be discharged for use. The filter plate 21 can be used for secondary filtration. At the same time, the transmission shaft 26 can be driven to rotate inside the outlet pipe 19 by starting the motor 25, thereby driving the bevel gear 28 and the bevel gear 1 23 to engage and rotate. At the same time, through the rotation of the transmission shaft 26, the drainage fan blades 27 can be driven to quickly lead the water flow out of the box body 1, thereby achieving the effect of efficient drainage. At the same time, the U-shaped plate 20 can be used to protect the bevel gear 1 23 and the bevel gear 28, and the rotating shaft 22 can be driven to rotate through the bevel gear 1 23, thereby driving the cleaning brush 24 to clean the outer wall of the filter plate 21, thereby further preventing blockage.
