A drain port 11 is provided in the middle of the lower end of the reactor 1, and the lower end of the drain port 11 is connected to a valve body 3; the cover body 2 is fixed to the upper end of the reactor 1, and a liquid adding hole 21 for adding copper-containing waste liquid into the reactor 1 is provided in the middle of the cover body 2, and a feeding hopper 4 for adding iron powder into the reactor 1 is also provided on the top of the cover body 2; the heating component is fixed on the cover body 2, and the heating end of the heating component extends into the reactor 1 and is used to heat the copper-containing waste liquid in the reactor 1; a plurality of electromagnets 5 are circumferentially connected to the outer wall of the reactor 1, and each electromagnet 5 extends in the vertical direction.

[0019] When the utility model is in use, first, a staff member can add the waste plating solution (copper-containing wastewater) into the reactor through the liquid adding hole located in the middle of the cover body, then energize the electromagnet, and then add iron powder into the reactor through the feeding hopper. Since the electromagnet generates magnetic force after being energized, the iron powder can be adsorbed on the inner wall of the reactor, and then the heating component is turned on to heat the waste plating solution (copper-containing wastewater) in the reactor. At this time, the iron powder can undergo a replacement reaction with the waste plating solution (copper-containing wastewater), and the replaced copper ions can be mixed in the waste plating solution (copper-containing wastewater), thereby achieving the purpose of recovering metallic copper in the waste plating solution (copper-containing wastewater) and producing ferrous sulfate crystals as a by-product.

After adopting this structure, when the electric heating rods are energized and heated, the electric heating rods can reliably heat the copper-containing wastewater in the reactor. Moreover, since the electric heating rods and the iron plates are circumferentially spaced, the copper-containing wastewater in the reactor can be evenly heated by several electric heating rods, and the copper-containing wastewater around each iron plate can be reliably heated, thereby improving the replacement efficiency of the iron plate for metallic copper in the copper-containing wastewater.
