Apparatus for recycling metal from metal ions containing waste solution
An apparatus for recycling metals from metal ions containing waste solution includes a conveying device, a reducing agent supplier and a solution supplier. The conveying device includes a first ferromagnetic conveyor belt, a first roller, and a second roller. The first and second rollers are substantially horizontally arranged, and the second roller is arranged at a lower position relative to the first roller and spaced from the first roller. The ferromagnetic conveyor belt is wrapped around the first and second rollers. The reducing agent supplier is used for supplying a reducing agent onto the first conveyor belt, the ferromagnetic conveyor belt is capable of conveying the reducing agent from the second roller to the first roller. The solution supplier is configured for supplying the waste solution onto the first conveyor belt.
1. An apparatus for recycling metals from metal ions containing waste solution, comprising:
a conveying device including a first ferromagnetic conveyor belt, a first roller, and a second roller, the first and second rollers being substantially horizontally arranged, and the second roller being arranged at a lower position relative to the first roller and spaced from the first roller, the ferromagnetic conveyor belt wrapping around the first and second rollers;
a reducing agent supplier for supplying a reducing agent onto the first conveyor belt, the ferromagnetic conveyor belt being capable of conveying the reducing agent from the second roller to the first roller;
a flow guiding member having a surface for solution to flow thereon and a protrusion formed on the surface for reducing flowing speed of the solution; and
a solution supplier configured for supplying the waste solution onto the flow guiding member, the flow guiding member disposed between the solution supplier and the first conveyor belt.
2. The apparatus of claim 1 , wherein the flow guiding member is adjacent to the first conveyor belt and is inclined at an acute angle relative to the first conveyor belt.
3. The apparatus of claim 1 , wherein a flow direction of the solution on the first conveyor belt is opposite to a conveying direction of the reducing agent.
4. The apparatus of claim 1 , wherein the solution supplier and the reducing agent supplier are disposed at opposite sides of the first conveyor belt.
5. The apparatus of claim 1 , wherein the reducing agent supplier includes a second ferromagnetic conveyor belt adjacent to the first conveyor belt for attracting and conveying reducing agent, and a ferromagnetic force generated by the first conveyor belt is larger than that generated by the second conveyor belt.
6. The apparatus of claim 1 , further comprising a scraping member for removing the product from the first conveyor belt.
