The cutting knife 202 is located between the adjacent blocking plates 203. A regulating component is provided at one end of the crushing tank 101.

[0031] Further Figure 6 As shown, the regulating component includes an inclined tube 300, which is connected to the bottom of one end of the crushing tank 101, an electric push rod 301 is fixed to one side of the bottom surface of the inner wall of the inclined tube 300, and a resistance plate 302 is fixed to the output end of the electric push rod 301. The bottom surface of the outer wall of the inclined tube 300 close to the crushing tank is connected to a discharge pipe 303, and the bottom end of the discharge pipe 303 is connected to the top surface of the copper dissolving tank body 100.

[0032] By setting the electric push rod 301 and the contact plate 302, the connection between the inclined tube 300 and the crushing tank 101 can be opened and closed, so as to facilitate the cut copper bars to enter the copper dissolving tank body 100 from the discharge pipe 303, and to position one end of the uncut copper bars, so as to facilitate the cutting of the copper bars.

[0033] Further Figure 3As shown, a bottom tube 504 is rotatably connected at the center of the bottom surface of the inner wall of the copper-dissolving tank body 100, and a gas collecting plate 500 is connected to the top surface of the bottom tube 504. The outer wall of the gas collecting plate 500 does not contact the inner wall of the copper-dissolving tank body 100, and there is a gap before. The bottom surface of the outer wall of the gas collecting plate 500 does not contact the bottom surface of the inner wall of the copper-dissolving tank body 100, and there is a gap before. A plurality of vent pipes 501 distributed in a circle are connected to the top surface of the gas collecting plate 500, and a plurality of evenly distributed transverse tubes 502 are connected to the outer wall of the vent pipe 501, and exhaust holes 503 are respectively provided on opposite sides of the outer wall of the transverse tube 502.

The rotation of the connecting rod 201 drives the cutting knife 202 to rotate. The cutting knife 202 rotates to cut the copper strip between the adjacent blocking plates 203, so that the copper strip is cut into multiple sections. Then, the electric push rod 301 is started. The output end of the electric push rod 301 moves to drive the contact plate 302 to move, so that the connection between the inclined tube 300 and the crushing tank 101 is opened. At this time, the copper sheet formed after cutting moves out of the crushing tank 101 into the inclined tube 300 under the action of gravity, and finally exits from the outlet.

The air pump 507 pumps air 507 into the gas collecting plate 500, and finally discharges it from the exhaust hole 503 into the sulfuric acid solution to provide oxygen for the reaction. Finally, the copper sheet and the sulfuric acid solution react to generate copper sulfate solution. When the copper sulfate solution is taken out, the valve 701 is opened, and the copper sulfate solution is discharged from the copper dissolving tank body 100 to the collecting device at the bottom.
