[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0036] The present invention also discloses a method for controlling the temperature gradient of low-silver and low-sulfur ultra-high purity copper purification, which specifically comprises the following steps:

[0037] S1. During the overall operation, when the solution in the electrolytic cell 203 is electrolyzed, heat needs to be provided by the water bath 201. When the temperature of the water bath 201 is maintained at a certain temperature value, the electrolysis efficiency inside the electrolytic cell 203 reaches the best. After a large amount of solution is electrolyzed in the electrolytic cell 203, it can be sent to the drying box 403 through the liquid outlet pipe 204 for drying. The condensation pipe 407 discharges the water vapor generated when the drying box 403 is dried into the liquid storage tank 408 for collection. The internal temperature of the water in the water bath 201 will gradually decrease during the heating process of the electrolytic cell 203. The water in the electrolytic cell 203 and the transition water tank 301 can be sent to the heating water tank 401 through the direct current water pipe 6 for heating. The water in the first branch water pipe 7 and the second branch water pipe 9 is then acted on by the water pump 8, so that the heated liquid can be cooled through the first branch water pipe 7 and the second branch water pipe 9. When the heated liquid reaches a suitable temperature, it can be sent to the water bath 201 for recycling.

[0038] S2, the dried solids in the drying box 403 are sent to the storage box 409 through the first discharge pipe 410 and the first feed pump 412 for storage. When the electrolytic cell 203 needs to add solution, the solid material to be electrolyzed is sent to the configuration box 302 through the second discharge pipe 411 and the second feed pump 413. The liquid distribution pipe 5 sends the liquid in the liquid storage tank 408 to the configuration box 302 for solid-liquid mixing;

[0039] S3. The transition water tank 301 preheats the solution configured in the configuration box 302 to avoid the influence of the configured solution with low temperature added into the electrolytic cell 203 on the original solution in the electrolytic cell 203.

[0040] During use, when the whole is working, when the solution inside the electrolytic cell 203 is electrolyzed, heat needs to be provided by the water bath 201. When the temperature of the water bath 201 is maintained at a certain temperature value, the electrolysis efficiency inside the electrolytic cell 203 reaches the best. After a large amount of solution is electrolyzed in the electrolytic cell 203, it can be sent to the drying box 403 through the liquid outlet pipe 204 for drying. The condensation pipe 407 discharges the water vapor generated when the inside of the drying box 403 is dried into the liquid storage tank 408 for collection. The internal temperature of the water in the water bath 201 will gradually decrease during the heating process of the electrolytic cell 203. The water inside the electrolytic cell 203 and the transition water tank 301 can be sent to the heating water tank 401 through the direct current water pipe 6 for heating. The first branch water pipe 7 and the second branch water pipe 9 are then regulated by the water pump 8. The heated liquid can be cooled by the first branch water pipe 7 and the second branch water pipe 9, and sent to the water bath 201 for recycling when the appropriate temperature is reached; the solid dried in the drying box 403 is sent to the storage box 409 for storage through the first discharge pipe 410 and the first feed pump 412. When the electrolytic cell 203 needs to add solution, the solid matter to be electrolyzed is sent to the configuration box 302 through the second discharge pipe 411 and the second feed pump 413, and the liquid distribution pipe 5 sends the liquid in the liquid storage tank 408 to the configuration box 302 for solid-liquid mixing; the transition water tank 301 preheats the solution configured in the configuration box 302, avoiding the influence of the low temperature of the configured solution added to the electrolytic cell 203 on the original solution in the electrolytic cell 203.

[0041] In summary: when using the overall device to purify low-silver, low-sulfur ultra-high purity copper, the solution can be electrolyzed by the electrolysis mechanism 2, and at the same time, the circulation mechanism 3 can effectively control and recycle the water temperature of the water bath heated during electrolysis, and then the electrolyzed solution is recovered and heated by the recovery mechanism 4 to reduce waste and loss of resources. When the DC power supply 208 on the top of the support frame 207 is turned on, the anode plate 210 and the cathode plate 211 can be connected through the line 209 to electrolyze the solution inside the electrolytic cell 203. The solution inside the electrolytic cell 203 is filtered and partitioned through the copper mesh 205 and the filter membrane 206, so that the required pure copper can be adsorbed on the cathode plate 2 11, and when the water bath heating temperature of the electrolytic cell 203 by the water bath 201 reaches 55 degrees Celsius, the electrolysis effect inside the electrolytic cell 203 is the best. At this time, the first guide vane 19 can be driven to rotate by the stirring rod 10 inside the transition water tank 301, so that the water with a lower temperature at the bottom of the water bath 201 can move to the inside of the transition water tank 301, and then the water is sent to the inside of the heating water tank 401 for recycling through the direct current water pipe 6. The high temperature of the water inside the heating water tank 401 is heated by the electric heating wire 402, and the water pump 8 extracts the high temperature water through the second branch water pipe 9, and sends it to the inside of the transition leakage pipe 202 inside the water bath 201 through one of the branches of the first branch water pipe 7. The first branch water The pipe 7 and the second branch water pipe 9 can cool the high-temperature water during transportation, so that the transition leakage pipe 202 can evenly deliver water of suitable temperature to the inside of the water bath 201. After the solution in the electrolytic cell 203 is electrolyzed, the outlet pipe 204 can be opened by the electric valve 26, and the electric telescopic rod 16 at the position of the first auxiliary frame 11 is extended and retracted between the guide rod 15 and the connecting rod 17, so that the gear 18 at the position of the connecting rod 17 can be connected to the gear 18 at the position of the first transition rod 13, thereby driving the guide rod 15 to rotate inside the outlet pipe 204, and then delivering the solution inside the electrolytic cell 203 to the inside of the drying box 403 for drying. When the solution enters the drying box 403, the electric telescopic rod 16 at the position of the first auxiliary frame 11 is extended and retracted between the guide rod 15 and the connecting rod 17, so that the gear 18 at the position of the connecting rod 17 can be connected to the gear 18 at the position of the first transition rod 13, thereby driving the guide rod 15 to rotate inside the outlet pipe 204, and then delivering the solution inside the electrolytic cell 203 to the inside of the drying box 403 for drying. After the drying process is complete, the water inside the heating water tank 401 can be heated to a high temperature by the electric heating wire 402 inside the heating water tank 401 outside the drying box 403, so that the water content of the solution inside the drying box 403 can be condensed through the condensation pipe 407 and stored in the liquid storage tank 408. The electric hydraulic rod 406 outside the drying box 403 pulls the pull rod 405, so that the pull rod 405 can drive the displacement grid 404 to slide continuously inside the drying box 403, thereby accelerating the drying of the solution. At the same time, the solid produced after the solution is dried can be sent to the position of the first discharge pipe 410, and then sent to the storage box 409 for storage through the first feeding pump 412, thereby reducing the loss of raw materials in the solution.

[0042] When it is necessary to configure the solution used in the electrolytic cell 203, the second feeding pump 413 can be used to act on the second discharge pipe 411, so that the solid material in the storage box 409 can be more accurately delivered to the configuration box 302. At the same time, the electric telescopic rod 16 is extended and retracted between the guide rod 15 and the connecting rod 17 at the second auxiliary frame 12 position, so that the gear 18 on the connecting rod 17 is meshed and connected with the gear 18 on the second transition rod 14, and then the guide rod 15 can be driven to rotate inside the liquid distribution pipe 5, so that the liquid distribution pipe 5 can deliver the water in the liquid storage tank 408 to the configuration box 302 according to the required amount. The stirring rod 10 inside the configuration box 302 drives the rotation of the second guide vane 20, so that the water and solid material in the configuration box 302 can be mixed according to the required proportion. At the same time, through another branch of the first branch water pipe 7 The heated water is sent to the transition water tank 301, so that the transition water tank 301 can preheat the solution after configuration in the configuration box 302, reducing the impact of the configured solution entering the electrolytic cell 203 on the temperature of the original solution in the electrolytic cell 203. After the solution in the configuration box 302 is configured and preheated, the liquid pump 303 extracts the solution in the configuration box 302 through the first material pipeline 304 and sends it to the electrolytic cell 203 through the second material pipeline 305 for electrolysis. When the rotating motor 25 is turned on, the stirring rod 10 and the first transition rod 13 can be rotated synchronously through the action of the first wheel 21 and the first belt 23. At the same time, the second transition rod 14 can be rotated synchronously with the first transition rod 13 through the action of the second wheel 22 and the second belt 24, thereby improving the convenience of the overall device.

When the whole system is working, when the solution in the electrolytic cell (203) is electrolyzed, heat needs to be provided by the water bath (201). When the temperature of the water bath (201) is kept at a certain temperature value, the electrolysis efficiency inside the electrolytic cell (203) reaches the best. After a large amount of solution is electrolyzed in the electrolytic cell (203), it can be sent to the drying box (403) through the liquid outlet pipe (204) for drying. The condensation pipe (407) discharges the water vapor generated during the drying process inside the drying box (403) into the liquid storage tank (408) for collection. The internal temperature of the water in the water bath (201) will gradually decrease during the process of heating the electrolytic cell (203). The water in the electrolytic cell (203) and the transition water tank (301) can be sent to the heating water tank (401) through the direct current water pipe (6) for heating treatment. Then, the water pump (8) acts on the first branch water pipe (7) and the second branch water pipe (9), so that the heated liquid can be cooled through the first branch water pipe (7) and the second branch water pipe (9) and sent to the water bath (201) for circulation when the temperature reaches a suitable level. S2. The solid dried in the drying box (403) is sent to the storage box (409) through the first discharge pipe (410) and the first feed pump (412) for storage. When the electrolytic cell (203) needs to add a solution, the solid material to be electrolyzed is sent to the configuration box (302) through the second discharge pipe (411) and the second feed pump (413). The liquid distribution pipe (5) sends the liquid in the storage box (408) to the configuration box (302) for solid-liquid mixing. S3. The transition water tank (301) preheats the solution configured in the configuration box (302), thereby preventing the configuration solution having a low temperature from being added into the electrolytic cell (203) and affecting the original solution in the electrolytic cell (203).
