Description

Technical Field

[0001] The utility model mainly relates to the technical field of copper dissolution, and specifically provides a device for improving the copper dissolution rate. Background Art

[0002] In copper foil production, copper dissolution provides electrolyte for raw foil, and generally uses copper wire or copper bar as raw material. The copper raw material first contacts with air or oxygen to be oxidized to form copper oxide, and then the copper oxide reacts with dilute sulfuric acid to form copper sulfate.

[0003] The existing copper dissolution methods include spray copper dissolution and immersion copper dissolution; in spray copper dissolution, the copper material is placed in a copper dissolution tank, and an annular spray port is arranged above the copper material. The copper material is completely exposed to the air, and the copper material can be well oxidized. However, the dilute sulfuric acid can only be sprayed onto the surface of the copper material from the spray port, and there are dead angles. The oxidized copper material and dilute sulfuric acid cannot be in full contact, which affects the copper dissolution speed. Although the existing spray copper dissolution device can spray the copper foil from multiple angles by setting an annular pipe during spraying to ensure that the copper raw material can be fully dissolved, the copper raw material at the bottom cannot be sprayed and can only be dissolved by the flowing liquid, resulting in a slow copper dissolution rate. And although the spray heads are set in a ring shape, due to the irregular shape of the stacked copper raw materials themselves, there will still be dead angles that cannot be sprayed during spraying by the annular spray heads, affecting the spraying effect of the copper raw material. Summary of the Utility Model

[0004] The technical solution of the utility model provides a solution significantly different from the prior art for the technical problem that the prior art solution is too single, and mainly provides a device for improving the copper dissolution rate to solve the technical problem that the existing annular spray heads cannot ensure that the stacked copper raw materials can be sprayed at each dead angle and the copper raw materials at the bottom can only be dissolved by the flowing-down liquid, resulting in a slow rate, as mentioned in the above background art.

[0005] The technical solution adopted by the utility model to solve the above technical problem is as follows:

[0006] A device for improving the copper dissolution rate includes a cylinder body, a cleaning cage for placing copper raw materials is arranged inside the cylinder body, an annular spray pipe for cleaning the copper raw materials inside the cleaning cage is arranged inside the cylinder body, a motor is arranged on one side of the cylinder body, and a transmission component is arranged between the motor and the cleaning cage and the annular spray pipe.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the motor is started, the motor drives the annular spray pipe to move downward from top to bottom through the transmission assembly. At the same time, the motor drives the cleaning cage containing copper raw materials to rotate through the transmission assembly. Through the annular arrangement of the spray pipe and the rotation of the cleaning cage, and the continuous descent of the annular spray pipe, it is possible to achieve non-dead-angle spraying of the stacked copper raw materials, and the copper raw materials stacked below can also be directly sprayed by the annular spray pipe, effectively improving the rate of overall copper dissolution treatment of the copper raw materials.

A transmission component is provided between the motor 10 and the cleaning cage 5 and the annular spray pipe 8.

[0025] The specific operation process of the present utility model is as follows: Place the copper raw materials inside the cleaning cage 5, and then turn on the annular spray pipe 8. The annular spray pipe 8 is provided with a circle of nozzles. Dilute sulfuric acid is sprayed on the cleaning cage 5 through the nozzles, and the copper raw materials are subjected to copper dissolution treatment with dilute sulfuric acid. At the same time, start the motor 10. The motor 10 drives the annular spray pipe 8 to descend through the transmission component, and at the same time, the motor 10 drives the cleaning cage 5 to rotate through the transmission component. The cleaning cage 5 drives the internal copper raw materials to rotate and cooperate with the annular spray pipe 8 to enable the dilute sulfuric acid to be sprayed on the stacked copper raw materials at any angle. At the same time, the annular spray pipe 8 descends to spray dilute sulfuric acid on the stacked copper raw materials from top to bottom, so that the copper raw materials at the lower part can all be sprayed with copper raw materials, rather than performing copper dissolution treatment with the dilute sulfuric acid flowing down.

[0026] Please refer to Figure 1 , a drain port 2 is opened at the bottom of the cylinder body 1, and a valve 3 is provided on the drain port 2.

[0027] The lower part of the cylinder body 1 is conical, and the sewage at the bottom end inside the cylinder body 1 will flow downward along the inner wall of the cone into the sewage discharge port 2. By opening the valve 3, the sewage can be discharged from the sewage discharge port 2 out of the cylinder body 1.

[0028] Please refer to Figure 3 and Figure 4 A rotating base 4 is provided at the bottom of the cleaning cage 5, and a support base 6 is provided inside the cylinder body 1. The rotating base 4 is rotatably connected above the support base 6, and a screen 7 is provided on the rotating base 4.

[0029] The copper raw material is placed above the screen 7 inside the cleaning cage 5. The annular spray pipe 8 sprays dilute sulfuric acid through the grid on the cleaning cage 5 onto the copper raw material. The sewage generated after the copper dissolution reaction will pass through the screen 7 and flow to the bottom of the cylinder body 1.

[0030] Please refer to Figure 2 and Figure 3 The transmission component includes a rotating shaft 11. The rotating shaft 11 is fixedly installed at the output end of the motor 10.

[0031] Start the motor 10. The motor 10 drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the threaded rod 12 to rotate through the bevel gear set 13. A threaded hole adapted to the threaded rod 12 is provided on the lifting block 9, and a limiting block is provided on one side of the annular spray pipe 8. A limiting rod is provided inside the cylinder body 1. The limiting block is slidably connected to the limiting rod to limit the annular spray pipe 8 to perform a linear lifting motion. The rotation of the threaded rod 12 drives the lifting block 9 to move up and down, and the lifting block 9 drives the annular spray pipe 8 to move up and down, so as to realize the spraying of dilute sulfuric acid on the copper raw material from top to bottom by the annular spray pipe 8.

[0032] Please refer to Figure 3 A circle of tooth blocks 15 is provided on the rotating base 4, and a spur gear 14 is fixedly installed on the threaded rod 12. The spur gear 14 meshes with the tooth blocks 15.

[0033] When the threaded rod 12 rotates, it drives the spur gear 14 to rotate. The spur gear 14 drives the rotating base 4 to rotate on the support base 6 through the tooth blocks 15. The rotating base 4 drives the cleaning cage 5 and the copper raw material inside to rotate, so that the copper raw material can rotate and change angles for spraying dilute sulfuric acid, and cooperate with the annular spray pipe 8 to realize spraying dilute sulfuric acid without dead angles.
