The ends can block the tailings so that the tailings falling onto the surface of the conveyor belt 14 can move with the conveyor belt 14. Water retaining rings 8 are fixedly connected to both ends of the middle part of the dewatering cylinder 1, and the water retaining rings 8 are both located at the connection between the rotary drum screen 9 and the inlet and outlet joints 10. The two groups of water retaining rings 8 have inclined surfaces facing the middle, which can make the thrown water droplets gather in the middle of the dewatering cylinder 1. Rollers 15 are rotatably connected to both ends of the drying box 2. The two groups of rollers 15 are connected by the conveyor belt 14, and the conveyor belt 14 is located inside the drying box 2. The conveyor belt 14 is driven to rotate by the rollers 15, so that the conveyor belt 14 moves with the metal tailings, thereby facilitating the drying of the metal tailings.

[0032] Working principle: When in use, the device is installed at a designated position through an external fixing frame, a wastewater collection bucket is placed at the lower end of the water outlet pipe 4, and a dried tailings collection device is placed below the end of the drying box 2 away from the dehydration cylinder 1. The device is started through an external controller, and the fixed shaft 12 is driven to rotate by the first servo motor 6, and the filter cylinder 11 is driven to rotate by the fixed shaft 12. The fixed shaft 12 drives the rotating shaft 13 to rotate through the limit block, and the second servo motor 16 drives the conveyor belt 14 to rotate through the roller 15. The heater 18 heats the air inside the drying box 2, and two groups of third servo motors 21 drive two groups of fan blades 22 to rotate. The outside air is allowed to enter the drying box 2 from the air inlet pipe 19, and the tailings are placed in the feed pipe 3. The tailings entering the feed pipe 3 fall from the opening on the inlet and outlet joint 10 to the middle of the inlet and outlet joint 10, and the tailings are driven to the middle of the filter cylinder 11 by the spiral blades. The oblique stirring arm drives the tailings to move in the direction of the discharge pipe 7. At the same time, the rotation of the filter cylinder 11 and the oblique stirring arm can drive the tailings to rotate, so that the moisture on the surface of the tailings is thrown to the inner surface of the dehydration cylinder 1. The water droplets on the inner surface of the dehydration cylinder 1 will flow to the middle of the outlet pipe 4 along the slope of the surface of the dehydration cylinder 1. The water retaining ring 8 can prevent the water droplets from being thrown out of the range of the outlet pipe 4. At the same time, the side of the water retaining ring 8 facing the filter cylinder 11 is an inclined surface, which can make the water droplets flow along the inclined surface of the water retaining ring 8 to the middle of the water outlet pipe 4, and then fall into the wastewater collection bucket, remove most of the water on the surface of the tailings, and the oblique stirring arm pushes the tailings to the inlet and outlet joint 10 at the upper end of the discharge pipe 7. At the same time, the tailings that continuously enter the filter cylinder 11 will also push the previous tailings into the inlet and outlet joint 10 at the upper end of the discharge pipe 7. The tailings inside the inlet and outlet joint 10 are transported to the upper end of the discharge pipe 7 by the spiral blades, and the tailings will pass through the inlet and outlet joint 10 and fall into the middle of the discharge pipe 7, and then fall onto the surface of the conveyor belt 14. The lower end of the discharge pipe 7 blocks the tailings, so that the tailings can only move with the conveyor belt 14. In the process of the conveyor belt 14 moving with the tailings, the heater 18 will heat the air in the middle of the drying box 2, and drive the two sets of fan blades 22 to rotate through two sets of third servo motors 21, so that the outside air is accelerated to enter the dehydration cylinder 1, driving the hot air flow inside the dehydration cylinder 1, and the flowing air flows out from the upper end of the drying box 2 away from the dehydration cylinder 1, thereby evaporating the moisture on the surface of the tailings, and the evaporated moisture will flow to the outside with the air, achieving the effect of complete dehydration, and finally the conveyor belt 14 brings the completely dehydrated tailings to the inside of the tailings collection device.
