The right bottom of the liquid extraction tube 8 is fixedly connected with a central tube 9. The central tube 9 is used to transport the dissolved copper or solution to the next processing stage.

[0022] Reference Figure 3 As shown, a liquid outlet pipe 901 is provided at the top of the center tube 9, and the liquid outlet pipe 901 is used to transport the solution to the next stage of processing or collection. An air cavity 902 is provided inside the center tube 9, and the air cavity 902 may be used to control the direction of gas introduction or solution flow.

[0023] Reference Figure 1 As shown, a gauze is provided inside the air inlet 904, the liquid outlet 10 is communicated with the liquid cavity 501, a liquid outlet 10 is provided at the bottom of the central tube 9, and the liquid outlet 10 is used to discharge the treated solution out of the system, a bottom seal 11 is provided inside the copper dissolving tank body 1, and the bottom seal 11 ensures that the solution will not leak from the bottom, and a support column 13 is fixedly connected to the bottom of the bottom seal 11, a manhole 14 is provided on the right side of the copper dissolving tank body 1, and a partition 12 is provided at the bottom of the partition 2, and the partition 12 is used to filter solid impurities and maintain the purity of the solution.

[0024] Working principle: During operation, the cleaned copper raw materials enter the copper dissolving tank from the feeding port 101 and the feeding port 2 102, and are evenly spread on the partition 2. Then, the electrolyte obtained by the reaction of the copper raw materials and sulfuric acid passes through the overflow port 3 and is transported to the liquid cavity 2 502 from the overflow port 4. Then, after the circulation pump 6 is started, the electrolyte in the liquid cavity is filtered through the liquid extraction port 7 and enters the central tube 9 through the liquid extraction pipe 8. Since the internal structure of the central tube 9 includes a liquid outlet pipe 901, an air cavity 902, and a liquid inlet pipe 903, air enters the air cavity 902 through the air inlet 904, and then the electrolyte flows out through the liquid outlet pipe 901. The pipe becomes thinner and the flow rate increases, driving the air flow in the air cavity 902 to mix with the electrolyte and enter the liquid inlet pipe 903. The obtained electrolyte flows out through the liquid outlet 10 Entering the liquid cavity 501, the electrolyte rises and passes through the partition 12 and the partition 2 in turn. The partition 12 splits the air in the electrolyte into small bubbles, so that the sulfuric acid, air and the surface of the copper material are fully contacted. Finally, the electrolyte level continues to rise. When it is higher than the overflow port 3, the electrolyte continues to circulate as above. Since the air inlet 904 is placed horizontally and a fine mesh is installed at the pipe mouth, the entry of impurities can be reduced and the cleanliness of the solution can be improved. The diameter of the liquid inlet pipe 903 is reduced and the flow rate is accelerated, which drives the gas in the air to reach the air cavity 902 through the air inlet 904 to mix with the solution for reaction. No additional air pump is needed to draw air. At the same time, the liquid rises after passing through the liquid outlet 10. When the liquid extraction port 7 is blocked or crystallized, the manhole 14 is provided to facilitate maintenance personnel to enter for maintenance.
