Description

Technical Field

[0001] This utility model relates to the field of refined copper production technology, specifically to a cathode copper hot washing device. Background Technology

[0002] In the electrolytic refining process, quality inspection of cathode copper is a crucial step in ensuring that the product meets national standards. To check the performance of the cathode copper, sampling and testing are necessary before the product is packaged and stored. Therefore, sampling, sample preparation, and testing of cathode copper are indispensable steps in the production process.

[0003] In the testing of cathode copper, the cleanliness of the sample is crucial to the accuracy of the test results. During the production process, cathode copper samples may adhere to copper anode sludge, electrolyte, and other impurities. If these impurities are not removed, they will severely affect the accuracy of the test analysis results, leading to failure to meet national quality standards. Therefore, before sampling, the cathode copper anode plate must be hot-washed to ensure the cleanliness of the sample. Hot-washing of cathode copper is an important surface treatment process in cathode copper production, mainly used to remove residual electrolyte, impurities, and deposits from the cathode copper surface, thereby improving product quality.

[0004] Existing cathode copper hot washing methods typically involve using a cathode copper stripping unit to perform hot washing on samples, followed by a secondary wash with high-temperature, high-pressure water to further remove residual impurities. However, the number of cathode copper samples is relatively small, while the stripping unit's cleaning water tank has a large capacity. Therefore, hot washing cathode copper samples requires a large amount of steam to heat the cleaning water, resulting in prolonged heating time and significant energy waste. Furthermore, the extended time required to heat the cleaning water not only increases the waiting time for hot washing water heating, reducing production efficiency, but also increases production costs. Utility Model Content

[0005] The purpose of this invention is to provide a cathode copper scalding and washing device that allows for flexible adjustment of the scalding and washing space and is energy-efficient, in order to solve the technical problems of excessive steam consumption, excessive heating time, serious energy waste, and low scalding and washing efficiency caused by the excessively large volume of the cleaning water tank in existing scalding and washing devices.

[0006] To solve the above technical problems, the solution adopted by this utility model is as follows:

[0007] A cathode copper scalding device includes a tank body, which is equipped with a steam pipe, a liquid inlet pipe A, an overflow box, a liquid return port A, and a partition. Several slots are provided on the left side of the tank body. The partition is connected to the tank body through the slots. The tank body is divided into compartment A and compartment B by the partition and slots. The steam pipe and liquid inlet pipe A are installed on one side of compartment A. One end of the steam pipe is fixedly installed in the bottom inner wall of compartment A and has several steam distribution holes. The overflow box is located in the upper right corner inside compartment A. The liquid return port A is installed at the bottom of compartment A and is sealed with a lead plug. Both the steam pipe and the liquid inlet pipe A are equipped with on / off valves. The steam pipe is connected to an external steam device for steam introduction, and the liquid inlet pipe A is used to inject scalding liquid into the tank body.

[0008] The partitions can be placed in different slots according to the required number of cathode copper samples, thereby changing the size of compartments A and B. This allows compartment A to be adapted to different numbers of cathode plate samples, providing a wide range of adaptability. The inlet pipe A is opened to inject the scalding solution into compartment A. The steam pipe is opened, and steam is evenly distributed to the bottom of compartment A through the steam distribution holes, heating the scalding solution to maintain a temperature of 75℃-80℃. The cathode copper sample is then suspended into compartment A for scalding. The overflow box ensures that the temperature inside compartment A remains constant. The liquid level is controlled. When the liquid level is too high, the scalding solution is discharged through the overflow box to ensure a stable liquid level. The overflowing scalding solution is circulated back to compartment A through an external return device, creating a circulating flow. After scalding, the lead plug at return port A can be opened to drain the scalded liquid, cleaning the residue and partitions at the bottom of the tank, preparing for the next scalding operation. The steam distribution holes on the steam pipe allow steam to fully contact the scalding solution, quickly heating it to the required temperature, shortening heating time and improving scalding efficiency. Compartment B provides additional scalding space, allowing for expansion of the scalding area as needed to accommodate different numbers of cathode copper samples, or for cleaning items that do not require heating.

[0009] Furthermore, the partition is equipped with a sealing strip; the partition is tightly fitted to the slot via the sealing strip; the size of compartment A and compartment B can be adjusted in the tank via the partition and the slot. A lifting hole is provided above the partition to facilitate lifting the partition out of the tank or changing its position within the tank using an external device.

[0010] When the partition is inserted into the slot, it fits tightly with the slot through the sealing strip, forming a sealed structure that effectively prevents the scalding solution from leaking out of the gap between the partition and the tank. By moving the partition's position within the tank, the size of compartments A and B can be flexibly adjusted, allowing compartment A to accommodate different numbers or sizes of cathode copper samples. The scalding solution is heated in compartment A and used to clean the cathode copper samples. Compartment B is an expandable section of compartment A, allowing compartment A to be expanded or contracted according to actual needs. During the scalding process, the scalding solution in compartment A is effectively confined within compartment A through the sealing structure between the sealing strip and the slot, preventing leakage into compartment B.

[0011] Furthermore, the partition is made of fiberglass or stainless steel. Fiberglass or stainless steel partitions have good corrosion resistance and mechanical strength, can withstand the high temperatures of the liquid during the scalding process, extending the service life of the partition. Additionally, the weight of the fiberglass or stainless steel partition allows the sealing strip to fit tightly into the groove under gravity, effectively preventing the scalding liquid in compartment A from leaking into compartment B.

[0012] Furthermore, compartment B is provided with an inlet pipe B and a return port B; the inlet pipe B is installed on one side of compartment B; the return port B is located at the bottom of compartment B and is sealed with a lead plug. The lead plug is connected to one side of the tank body by a limiting rope.

[0013] When there are a large number of cathode copper samples to be scalded, remove the partition and merge compartments A and B to create a larger scalding space. Depending on the needs, scalding solution can be injected into the tank by switching inlet pipes A and B or by simultaneously opening both inlet pipes. Steam is then introduced through the steam pipe for heating. Once the appropriate temperature is reached, the cathode copper samples can be placed into the tank for scalding. If the area of ​​the scalding tank needs to be reduced, the partition can be inserted into the tank to divide it into compartments A and B. Compartment A is used for scalding, and the scalding solution in compartment B can be drained through the return port B by pulling out the lead plug with the limiting rope. When needed, compartment B can be used to clean items that do not require heated scalding solution, such as using a cleaning agent mixed with citric acid and oxalic acid to clean PbSO4 on the surface of the anode plate at room temperature, allowing one tank to clean two types of objects.

[0014] Furthermore, the height of the overflow box is 100-200 mm lower than the height of the partition. Because the overflow box is lower than the partition, excess liquid in compartment A can be drained through the overflow box, ensuring that the liquid level in compartment A does not exceed the height of the partition. This guarantees that the separation between compartment A and compartment B remains effective, preventing liquid from flowing from compartment A into compartment B.

[0015] The working principle of this utility model is as follows:

[0016] In use, determine the size of compartment A based on the number of cathode copper samples. Insert the partition into the slot and ensure it is tightly fitted to the slot using the sealing strip. Divide the tank into appropriate compartments A and B. Open inlet pipe A to inject scalding solution into compartment A. Open steam pipe; steam is evenly distributed to the bottom of compartment A through steam distribution holes to heat the scalding solution. Lower the cathode copper samples into compartment A for scalding. The overflow box ensures the liquid level in compartment A. If the liquid level is too high, the scalding solution is discharged through the overflow box to ensure a stable liquid level. An external reflux device is then used to return the solution to the tank. The overflowing scalding solution circulates back into compartment A, creating a continuous flow. After scalding, the lead plug at return port A is removed, and the scalding solution in compartment A is discharged through return port A. When the entire tank is needed to scald the cathode copper sample, the partition can be removed to connect compartment A and compartment B. Cleaning solution is then injected through inlet pipes A and B. The cleaning solution after scalding can be discharged through return ports A and B, facilitating tank cleaning. When cleaning other items that do not require heated cleaning solution, cleaning solution is injected into compartment B through inlet pipe B for cleaning.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. The partition of this utility model can be flexibly adjusted in the tank to adjust the size between compartment A and compartment B, so that the size of compartment A can be adapted to different numbers of samples as needed. This avoids the problem of excessive steam consumption and excessive heating time caused by excessively large cleaning water tank volume. Moreover, the steam distribution hole can make the steam fully contact the scalding liquid, quickly heat the scalding liquid, shorten the heating time, and improve the scalding efficiency.

[0019] 2. The partition of this utility model is tightly fitted to the slot with a sealing strip, which effectively prevents the leakage of hot washing liquid. The compartment B can also be used to clean items that do not require heating, which improves the versatility of the equipment, reduces production costs, and improves production efficiency.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0026] The following is a detailed description of the cathode copper hot washing device of this utility model with reference to the accompanying drawings: Example 1

[0027] A cathode copper hot washing device includes a tank 1, which is provided with a steam pipe 2, a liquid inlet pipe A3, an overflow box 4, a return port A5, and a partition 7. Several slots 11 are provided on the left side of the tank 1. The partition 7 is connected to the tank 1 through the slots 11. The tank 1 is divided into compartments A12 and B13 by the partition 7 and the slots 11. The steam pipe 2 and the liquid inlet pipe A3 are installed on one side of compartment A12. One end of the steam pipe 2 is fixedly installed in the bottom inner wall of compartment A12 and has several steam distribution holes 6. The overflow box 4 is located in the upper right of compartment A12. The return port A5 is installed at the bottom of compartment A12 and is sealed with a lead plug.

[0028] The working principle of this embodiment is as follows:

[0029] When scalding the cathode plate samples, according to the number of cathode copper samples, insert the partition 7 into the slot 11 on the right side to divide the tank 1 into compartment A12 and compartment B13. Open the liquid inlet pipe A3 to inject scalding solution into compartment A3. Open the steam pipe 2, and steam is evenly distributed to the bottom of compartment A12 through the steam distribution hole 6 to heat the scalding solution and maintain the temperature of the scalding solution at 75℃. Hang the cathode copper samples into compartment A12 to scald the cathode plate samples. The overflow box 4 can ensure the isolation The liquid level in chamber A12 is controlled. When the liquid level is too high, the scalding solution is discharged through the overflow box 4 to ensure a stable liquid level. The overflowing scalding solution is circulated back into chamber A12 through an external return device, creating a circulating flow. After scalding, the lead plug of the return port A5 can be opened to discharge the scalded liquid and clean the residue at the bottom of tank 1 and the partition 7, preparing for the next scalding operation. When cleaning anode copper that does not require heated cleaning solution, the anode copper can be cleaned through chamber B. Example 2

[0030] The difference from Embodiment 1 is that the partition 7 is provided with a sealing strip 71; the partition 7 is tightly fitted to the slot 11 through the sealing strip 71; the size of the compartment A12 and compartment B13 can be adjusted by the partition 7 and the slot 11; the partition 7 is made of fiberglass; the compartment B13 is provided with an inlet pipe B8 and a return port B9; the inlet pipe B8 is installed on one side of the compartment B13; the return port B9 is opened at the bottom of the compartment B13 and is sealed with a lead plug; the height of the overflow box 4 is 150mm lower than the height of the partition 7.

[0031] The fiberglass partition 7 possesses excellent corrosion resistance and mechanical strength, enabling it to withstand the high temperatures of the liquid during the scalding process and extending its service life. When the partition 7 is inserted into the slot 11, it is tightly fitted to the slot 11 via the sealing strip 71, forming a sealed structure. During the scalding process, the scalding liquid in compartment A12 is effectively confined within compartment A12 through the sealing structure between the sealing strip 71 and the slot 11, preventing leakage into compartment B13. The overflow box 4 is 150mm lower than the height of the partition 7, allowing excess liquid in compartment A12 to drain through the overflow box 7, ensuring that the liquid level in the tank 1 does not exceed the height of the partition 7. This ensures that the separation between compartment A12 and compartment B13 remains effective, preventing liquid from flowing from compartment A12 into compartment B13. When there are a large number of cathode copper samples to be scalded, remove the partition 7 and merge compartments A12 and B13 to form a larger scalding space. At the same time, open the two inlet pipes to inject scalding liquid into the tank 1. Then, open the steam pipe 2 and introduce steam into the scalding liquid through the steam distribution hole 6 for heating. Once the appropriate temperature is reached, the cathode copper samples can be placed into the tank 1 for scalding. After scalding, the lead plug can be pulled out by the limiting rope to allow the scalding liquid to be discharged through the return port A5 and return port B9.

[0032] The working principle of this embodiment is the same as that of Embodiment 1.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
