Description

Technical Field

[0001] The present invention relates to the technical field of metal electrolysis or electrowinning, and in particular to an electrolytic cathode nodule removal device and a method for removing nodules on the cathode. Background Art

[0002] In non-ferrous metal smelting, in the electrolytic cell of the electrolysis process, there are cathode plates and anode plates for electrolytic chemical reactions. After connecting direct current, nodule substances will be deposited on the surface of the metal cathode. The generation of such nodule substances will cause the cathode to be connected to the anode plate, resulting in a short-circuit phenomenon, which affects the current efficiency of electrolysis and the grade rate of the cathode-deposited metal, and is not conducive to the stability and high efficiency of electrolysis.

[0003] In the related art, after the cathode plate and the anode plate have an inter-electrode short circuit, there will be a phenomenon of excessive current distribution and excessive local magnetic field on the electrode plates. The current short-circuit detection methods are as follows: 1. Manually hold a drag meter and move it above the electrode plates, repeatedly detecting back and forth. If a short-circuit plate is detected, the drag meter will alarm, and then the short-circuit cathode plate will be extracted manually or by a crane, and the short-circuit nodule substances will be removed with a flat shovel; 2. Manually hold a water pipe and spray water on the conductive rod of the cathode plate, and then observe the water vapor evaporation situation after a period of time. The position where a large amount of fog is generated is considered to have a short-circuit plate, and then the short-circuit cathode plate will be extracted manually or by a crane, and the short-circuit nodules will be removed with a flat shovel.

[0004] The current inter-electrode short-circuit detection methods and nodule treatment methods have the following deficiencies: 1. Manual operation has a large labor intensity, low efficiency, and a poor working environment; 2. Short-circuit plates cannot be detected and processed in a timely manner, with poor timeliness and inability to ensure the current efficiency and product grade rate of electrolysis operations; 3. Manual operation relies on experience, with low accuracy in short-circuit detection, difficult to guarantee reliability, and low automation. Summary of the Invention

[0038] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0039] Refer to the following Figures 1-9 Describe the nodule removal device 100 for the electrolytic cathode 20 according to the embodiments of the present invention. The nodule removal device 100 for the electrolytic cathode 20 can be applied in the electrolysis field or the motor field.

[0040] As Figures 1-9As shown in the figure, the nodule removal device 100 for the electrolytic cathode 20 according to an embodiment of the present invention includes: a short-circuit detection unit 31, a plate transfer unit 32, a nodule removal unit 33, and a nodule image recognition unit 34. The short-circuit detection unit 31 is used to detect the short-circuited cathode 20 in the electrolytic cell 22. It should be noted that the short-circuit detection unit 31 is used to determine the exact position of the short-circuited cathode 20 in the electrolytic cell 22 by detecting and analyzing the temperature data and / or magnetic field intensity data of the cathode 20 in the electrolytic cell 22. The cathode 20 can be a cathode plate 24, and an anode plate 23 can be placed in the electrolytic cell 22. The plate transfer unit 32 is used to take out the short-circuited cathode 20 from the electrolytic cell 22, and the plate transfer unit 32 is also used to put the cathode 20 with the nodules removed back into the electrolytic cell. The nodule removal unit 33 can be a robot, and the nodule removal unit 33 is used to remove the nodules on the surface of the short-circuited cathode 20. The short-circuit detection unit 31 is responsible for quickly detecting the short-circuited cathode 20 in the electrolytic cell 22 to prepare for the next step of removing the nodules on the cathode 20. The plate transfer unit 32 is responsible for taking out the detected short-circuited cathode 20 from the electrolytic cell 22 and transporting it to the nodule removal location. Then, the nodule removal unit 33 removes the nodules on the short-circuited cathode 20 completely. Finally, the plate transfer unit 32 sends the cathode 20 with the nodule material 21 removed back to the original electrolytic cell 22. The plate transfer unit 32 is also used to grab the short-circuited cathode 20 and take it out of the electrolytic cell 22 and place it on the nodule removal unit 33. The nodule image recognition unit 34 can be used to obtain the actual data information of the nodules on the surface of the cathode 20, and the removal position can be set on the nodule removal unit 33. After detecting the short-circuited cathode 20, when the cathode 20 is taken out of the electrolytic cell 22 and placed at the nodule removal position, the nodule image recognition unit 34 obtains the actual data information of the nodules on the surface of the cathode 20. The actual data information can include: the position and size of the nodules.

[0041] It should be noted that the plate transfer unit 32 takes out the cathode 20 from the electrolytic cell 22 according to the exact position of the short-circuited cathode 20. The nodule image recognition unit 34 is used to identify the nodules on the surface of the short-circuited cathode 20 to obtain the position and size of the nodules on the surface of the cathode 20 during the process of the plate transfer unit 32 taking out the short-circuited cathode 20 from the electrolytic cell 22. The nodule removal unit 33 is used to remove the nodules on the surface of the short-circuited cathode 20 according to the position and size of the nodules on the surface of the cathode 20. The plate transfer unit 32 is also used to put the cathode 20 with the nodules removed back into the electrolytic cell 22.

[0042] Specifically, the short-circuit detection unit 31, the plate transfer unit 32, and the nodule removal unit 33 can all be connected to the controller 35. By detecting the short circuit of the cathode 20 in the electrolytic cell 22 through the short-circuit detection unit 31, the position of the short-circuited cathode 20 in the electrolytic cell 22 can be detected, and the short-circuited cathode 20 can be accurately positioned. Then the short-circuit detection unit 31 transmits the position information of the short-circuited cathode 20 to the controller 35, and the controller 35 controls the plate transfer unit 32 to take out the short-circuited cathode 20 from the electrolytic cell 22 and place it at the nodule removal unit 33. And the nodule image recognition unit 34 can be used to obtain the actual data information of the nodules on the surface of the cathode 20, and the cleaning position can be set on the nodule removal unit 33. Then the controller 35 controls the nodule removal unit 33 to remove the nodules (nodule substances 21) on the surface of the short-circuited cathode 20. After the nodule substances 21 on the surface of the short-circuited cathode 20 are removed, the controller 35 controls the plate transfer unit 32 to put the cathode 20 with the nodules removed back into the electrolytic cell 22. Such a setting can achieve accurate detection and positioning of the short-circuited cathode 20 first, and then remove the nodules on the surface of the cathode 20. Compared with the prior art, it is beneficial to improve the current efficiency and product grade rate of the electrolysis operation, does not require operators to manually remove the nodules, can reduce the labor intensity of the operators, can improve the nodule removal efficiency, and can timely and accurately find the position of the short-circuited cathode 20, increasing the reliability of the short-circuit detection. It should be noted that the cathode 20 can be the cathode plate 24. At the same time, the nodule removal device 100 is an intelligent device, and does not require operators to manually remove the nodules, which can improve the nodule removal efficiency.

[0043] In some embodiments of the present invention, the short-circuit detection unit 31 can also be used to detect the temperature data and / or magnetic field intensity data of the cathode 20 in the electrolytic cell 22, and determine the precise position of the short-circuited cathode 20 in the electrolytic cell 22 by analyzing the temperature data and / or magnetic field intensity data of the short-circuited cathode 20 through the short-circuit detection unit 31. It should be noted that the precise position of the short-circuited cathode 20 in the electrolytic cell 22 can be determined by analyzing the temperature data and / or magnetic field intensity data of the short-circuited cathode 20 through the short-circuit detection unit 31. Compared with the prior art, such a setting can more accurately detect the position of the short-circuited cathode 20, and can improve the accuracy of the short-circuit detection. And the intelligent operation saves operation time and improves the detection efficiency.

[0044] In some embodiments of the present invention, the short-circuit detection unit 31 may include: an infrared imager and / or an electromagnetic induction meter and / or a reed switch. Among them, when the short-circuit detection unit 31 detects the short-circuited cathode plate 24 in the electrolytic cell 22, the infrared imager may first perform short-circuit area detection, and then the electromagnetic induction meter or the reed switch may accurately locate the short-circuited cathode plate 24. It is also possible that only the infrared imager locates the short-circuited cathode plate 24, or only the electromagnetic induction meter or the reed switch accurately locates the short-circuited cathode plate 24. The detection range of the infrared imager in the horizontal direction can at least cover the plates in the entire electrolytic cell 22. After detecting the short-circuited cathode plate 24 through the infrared imager and / or the electromagnetic induction meter and / or the reed switch, the position of the short-circuited cathode plate 24 can be accurately detected, thereby improving the working reliability of the nodule removal device 100. It should be noted that the infrared imager can obtain the temperature data of the cathode plate 24, and the electromagnetic induction meter and the reed switch can obtain the magnetic field data of the cathode plate 24. Furthermore, it is more reliable to determine the exact position of the short-circuited cathode plate 24 in the electrolytic cell 22 through the temperature data and / or the magnetic field intensity data, with high positioning accuracy, and intelligent operation saves operation time and improves work efficiency.

[0045] In some embodiments of the present invention, the nodule removal device 100 may further include: a signal processing unit 50, which is communicatively connected to the short-circuit detection unit 31, the nodule image recognition unit 34, and the controller 35. The nodule image recognition unit 34 stores preset data information and is used to obtain the actual data information of the nodules on the surface of the cathode 20. If the actual data information of the nodules does not fall within the preset data information, the plate transfer unit 32 will put the short-circuited cathode plate 24 back into the electrolytic cell 22. If the actual data information of the nodules falls within the preset data information, the signal processing unit 50 plans a path to remove the nodules on the surface of the cathode plate 24 according to the actual data information, and then the controller 35 controls the nodule removal unit 33 to remove the nodules on the surface of the cathode plate 24 according to the path of removing the nodules on the surface of the cathode plate 24. It should be noted that the preset data information of the nodules can be set in the nodule image recognition unit 34 and / or the controller 35. When the nodule image recognition unit 34 detects the actual data information of the nodules on the surface of the cathode plate 24, the actual data information is sent to the signal processing unit 50. The signal processing unit 50 can calculate the position and size of the nodules, and then the signal processing unit 50 plans a path to remove the nodules on the surface of the cathode plate 24 according to the actual data information, and then the controller 35 controls the nodule removal unit 33 to remove the nodules on the surface of the cathode plate 24 according to the path of removing the nodules on the surface of the cathode plate 24. Such a setting can facilitate the removal of the nodule 21 on the surface of the cathode plate 24 and improve the removal efficiency of the nodule 21.

[0046] In some embodiments of the present invention, the nodule removal unit 33 may include: a cathode clamping assembly and an electrolytic cathode nodule removal tool assembly 10 that combines hammering and milling functions. The tool assembly 10 is used to mill the nodules 21 (nodules) on the surface of the cathode 20. The cathode clamping assembly is used to fix the cathode 20 to facilitate the tool assembly 10 to remove the nodules 21. Such an arrangement can utilize the tool assembly 10 to quickly remove the nodules 21 on the surface of the cathode 20, and fix the position of the cathode 20 through the cathode clamping assembly, making the tool assembly 10 more accurate when removing the nodules 21.

[0047] In some embodiments of the present invention, the tool assembly 10 may include: a tool disc body 11, a hammering portion 12, and a milling member 13. The tool disc body 11 is the main part of the tool assembly 10. Driven by a driving member, the tool disc body 11 is adapted to rotate at a high speed around the central axis 14 of the tool disc body 11. The hammering portion 12 has a first side surface, a second side surface 124, and a third side surface 125 that are sequentially connected end to end. The first side surface is integrally formed with the side surface of the tool disc body 11 and the first side surface is a partial cylindrical surface. The second side surface 124 is a hammering surface 121. During the rotation of the tool disc body 11, the phase of the second side surface 124 is ahead of that of the third side surface 125. The third side surface 125 is configured as an involute surface, and the third side surface 125 is tangent to the side surface of the tool disc body 11. The hammering portion 12 and the tool disc body 11 may be configured as an integrally formed part. The hammering surface 121 is used to hammer the nodules 21 on the surface of the cathode 20. The milling member 13 is disposed on the side surface of the tool disc body 11. The taper of the installation area on the side surface of the tool disc body 11 for installing the milling member 13 is α, satisfying the relationship: 60° ≤ α ≤ 90°, and α corresponds to the main cutting edge angle of the milling member 13. Among them, the milling member 13 may be only disposed on the side surface of the tool disc body 11, or only disposed on the third side surface 125 of the hammering portion 12, or may be disposed on both the side surface of the tool disc body 11 and the third side surface 125 of the hammering portion 12. Preferably, the manufacturing material of the milling member 13 may be made of cemented carbide.

[0048] Among them, when removing the nodules 21, the tool assembly 10 can move in two directions, namely the X direction and the Y direction, on the surface of the cathode 20 (cathode plate 24). When the tool assembly 10 removes the nodules 21 on the surface of the cathode 20, the tool disc body 11 rotates according to Figure 1The arrow in it rotates counterclockwise at high speed and can move on the surface of the cathode 20 to remove the nodules 21. When the cutter head body 11 rotates, the hammering part 12 and the milling part 13 can rotate at high speed synchronously with the cutter head body 11. The hammering surface 121 first hammers the nodules 21 with a certain height. If the nodules 21 are not hammered clean, the milling part 13 will mill the remaining nodules 21 on the surface of the cathode 20 to clean the nodules 21 on the surface of the cathode 20. Compared with the prior art, the nodules 21 can be removed more cleanly. After the cathode 20 is put back into the electrolytic cell, the repeated short-circuit rate of the electrolytic cell can be reduced. When processing the electrolytic copper of the product into the finished product warehouse, the grade of the product can be improved. Moreover, the removal efficiency of the nodules 21 on the surface of the cathode 20 can also be improved.

[0049] Thus, through the cooperation of the cutter head body 11, the hammering part 12, and the milling part 13, when using the tool assembly 10 to remove the nodules 21 on the surface of the cathode 20, the hammering surface 121 of the tool assembly 10 first hammers the nodules 21, and then the milling part 13 mills the nodules 21, forming a nodule removal process of hammering first and then milling. Compared with the prior art, the larger nodules 21 (greater than 3 mm) are removed by hammering with the protruding hammering part 12 on the cutter head body 11, and the smaller nodules 21 (greater than 1 mm and less than 3 mm) are removed by milling with the milling part 13 of the cutter head body 11. The cathode nodules 21 can be removed at one time with high removal efficiency, and nodules 21 of all sizes can be removed, which can reduce the possibility of repeated short circuits in the electrolytic cell and ensure the production quality of the product.

[0050] In some embodiments of the present invention, such as Figures 4-7 shown, the cross-section of the cutter head body 11 can be set to be circular. During the rotation of the cutter head body 11, such a setting can enable the cutter head body 11 to rotate smoothly around the central axis 14 of the cutter head body 11.

[0051] In some embodiments of the present invention, the hammering part 12 can be set to one or more, that is to say, the hammering part 12 can be set to one, or the hammering part 12 can also be set to multiple.

[0052] Furthermore, as Figures 4-7As shown, the hammering parts 12 can be provided in multiple numbers, and the multiple hammering parts 12 are evenly arranged in the circumferential direction of the cutter head body 11. Preferably, the hammering parts 12 are provided in two and evenly arranged, and the two hammering parts 12 can be symmetrically arranged about the central axis 14. When the cutter head body 11 rotates, the two hammering parts 12 can work simultaneously, and the two hammering parts 12 rotate at a high speed synchronously with the cutter head body 11. Such a setting can enable the rotating tool assembly 10 to achieve dynamic balance by itself, which is beneficial to the balance and stability of the rotation of the tool assembly 10, and can hammer and mill the nodules 21 on the surface of the cathode 20 more quickly, so that the nodules 21 can be removed more cleanly, and the removal efficiency of the nodules 21 on the surface of the cathode 20 can also be improved.

[0053] In some embodiments of the present invention, as Figures 4-7 shown, in the circumferential direction of the cutter head body 11, the interval angles between two adjacent hammering parts 12 are the same. Such a setting can enable the center of gravity of the tool assembly 10 to be located on the central axis 14, and can also make the mass distribution of the tool assembly 10 more uniform, which can avoid the instability of the center of gravity when the cutter head body 11 rotates at a high speed, so that the cutter head body 11 can rotate more smoothly, and further can ensure the effect and efficiency of the tool assembly 10 in removing the nodules 21. Moreover, the overall appearance of the tool assembly 10 can also be made more beautiful.

[0054] In some embodiments of the present invention, one or more milling parts 13 can be provided on the side surface of the cutter head body 11. It can also be understood that one milling part 13 can be provided on the side surface of the cutter head body 11, and multiple milling parts 13 can also be provided on the side surface of the cutter head body 11. Such a setting can ensure the milling effect of the tool assembly 10 and can ensure that the nodules 21 on the surface of the cathode plate are cleaned up.

[0055] In some embodiments of the present invention, as Figures 4-7 shown, at least one milling part 13 can be provided on each hammering part 12. It can also be explained that the number of milling parts 13 provided on each hammering part 12 is one or more. Preferably, one milling part 13 is provided on each hammering part 12. Such a setting can make the number of milling parts 13 appropriate, which can ensure that each hammering part 12 has the function of milling the nodules 21, so that the nodules 21 can be removed more quickly, and the incomplete cleaning of the nodules 21 can also be avoided.

[0056] In some embodiments of the present invention, as Figures 4-7As shown, a plurality of milling members 13 may be provided on the side surface of the cutter head body 11, and the plurality of milling members 13 are uniformly arranged in the circumferential direction of the cutter head body 11. Preferably, 2-4 milling members 13 may be provided on the side surface of the cutter head body 11, and the plurality of milling members 13 are evenly distributed in the circumferential direction of the cutter head body 11. The milling member 13 adjacent to the hammering portion 12 is spaced apart from the hammering portion 12. Such a setting can prevent the milling member 13 adjacent to the hammering portion 12 from interfering with the hammering portion 12, and can ensure the working performance of the hammering surface 121 and the milling member 13.

[0057] In some embodiments of the present invention, as Figures 4-7 shown, in the radial direction of the cutter head body 11, the hammering surface 121 may be perpendicular to the side surface of the cutter head body 11. Among them, if the angle between the hammering surface 121 and the side surface of the cutter head body 11 is too large, when the hammering surface 121 hammers the agglomerate 21, the agglomerate 21 is not easily hammered off. If the angle between the hammering surface 121 and the side surface of the cutter head body 11 is too small, the efficiency of hammering the agglomerate 21 will be low. Such a setting can make the angle between the hammering surface 121 and the side surface of the cutter head body 11 appropriate, can more easily hammer off the agglomerate 21, and can also improve the efficiency of hammering the agglomerate 21.

[0058] In some embodiments of the present invention, as Figures 4-7 shown, the milling member 13 is detachably provided on the hammering portion 12 and / or the cutter head body 11. It can also be understood that the milling member 13 installed on the hammering portion 12 and / or the cutter head body 11 can be disassembled at any time. As the most easily worn part of the tool assembly 10, when the working time of the milling member 13 is too long or it is worn due to external force, the milling member 13 can be replaced at any time, so as to extend the service life of the cutter head body 11.

[0059] Furthermore, the milling member 13 is detachably provided on the side surface of the cutter head body 11. Such a setting can replace the milling member 13 at any time after it is worn due to work, prevent the tool assembly 10 from not working due to the damage of the milling member 13, further improve the product quality, and ensure the cleaning efficiency.

[0060] In some embodiments of the present invention, as Figures 4-7As shown, the milling member 13 can be set as a milling cutter. In the circumferential direction of the milling member 13, multiple milling surfaces 15 can be provided on the side surface of the milling member 13, and each milling surface 15 can be provided with a main milling edge 132 and a secondary milling edge 133. It should be noted that the main milling edge 132 is a vertical cutting edge, and the secondary milling edge 133 is arranged parallel to the cross-section 20 of the metal plate. When the tool assembly 10 works, the main milling edge 132 plays the role of mainly cutting the agglomerates 21, and the secondary milling edge 133 can play an auxiliary cutting role. By milling the agglomerates 21 with the main milling edge 132 and the secondary milling edge 133, the efficiency of milling the agglomerates 21 can be improved. Moreover, when a certain milling surface 15 is worn out after long-term use, the milling member 13 is removed, and then the milling member 13 is installed on the tool assembly 10, so that the main milling edge 132 and the secondary milling edge 133 of another milling surface 15 mill the agglomerates 21. Such a setting can extend the service life of the milling member 13.

[0061] In some embodiments of the present invention, as Figures 4-7 shown, a groove 122 can be provided on the side surface of the cutter head body 11 and / or the outer surface of the hammering portion 12, and the groove 122 extends in the thickness direction of the cutter head body 11. The milling surface 15 of the milling member 13 is adapted to extend into the groove 122. Among them, a part of the main milling edge 132 and a part of the secondary milling edge 133 of the milling surface 15 extend into the groove 122. When the main milling edge 132 and the secondary milling edge 133 of the milling surface 15 mill the agglomerates 21, the residues of the agglomerates 21 generated can be discharged through the groove 122, so as to avoid the retention of the residues of the agglomerates 21 at the milling member 13, and further avoid the residues of the agglomerates 21 affecting the milling of the agglomerates 21 by the milling member 13.

[0062] In some embodiments of the present invention, as Figures 4-7 shown, an installation notch 134 communicating with the groove 122 can be provided on the side surface of the cutter head body 11 and / or the outer surface of the hammering portion 12, and the milling member 13 is installed at the installation notch 134. It can also be interpreted that the installation notch 134 is provided on the side surface of the cutter head body 11 and / or the outer surface of the hammering portion 12, and the milling member 13 is installed in the installation notch 134. Since the working intensity of the milling member 13 is high, when the milling member 13 mills the agglomerates 21, the side wall of the installation notch 134 can support and limit the milling member 13, and the loosening of the milling member 13 can be avoided. When the cutter head body 11 rotates, the milling member 13 can be prevented from detaching from the cutter head body 11, thereby preventing the milling member 13 from causing harm to the operator.

[0063] In some embodiments of the present invention, the diameter of the cutter head body 11 is less than 300 mm. Preferably, the minimum value of the diameter of the cutter head body 11 is set to 5 mm. Such a setting can make the diameter size of the cutter head body 11 more appropriate, ensure that a plurality of hammering parts 12 are provided on the side surface of the cutter head body 11, and also ensure that a plurality of milling parts 13 are provided on the cutter head body 11.

[0064] In some embodiments of the present invention, in the radial direction of the cutter head body 11, the length of the hammering surface 121 is less than 40 mm. Preferably, the minimum value of the length of the hammering surface 121 is set to 5 mm. When the hammering surface 121 hammers the nodule 21, the length of the hammering surface 121 determines the size of the nodule 21 that the tool assembly 10 can hammer. If the length of the hammering surface 121 is too small, it will not be able to hammer the too large nodule 21. Such a setting can make the length size of the hammering surface 121 appropriate, improve the effect of the hammering surface 121 hammering the nodule 21, and thus improve the hammering efficiency of the hammering surface 121.

[0065] In some embodiments of the present invention, in the thickness direction of the cutter head body 11, the height of the hammering surface 121 is less than 50 mm. Preferably, the minimum value of the height of the hammering surface 121 is set to 2 mm. When the hammering surface 121 hammers the nodule 21, the height of the hammering surface 121 determines the height of the nodule 21 that the tool assembly 10 can hammer and mill. If the height of the hammering surface 121 is too small, it will not be able to hammer some too high nodules 21. Such a setting can make the height size of the hammering surface 121 appropriate, further improve the effect of the hammering surface 121 hammering the nodule 21, and thus further improve the hammering efficiency of the hammering surface 121.

[0066] According to the milling device of the embodiment of the present invention, including the tool assembly 10 of the above embodiment, the tool assembly 10 is arranged on the milling device, and the driving member of the milling device is adapted to drive the tool assembly 10 to rotate. When using the tool assembly 10 to remove the nodules 21 on the surface of the cathode 20, the hammering surface 121 of the tool assembly 10 first hammers the nodules 21, and then the milling part 13 mills the nodules 21, which can form a process of removing the nodules 21 by first hammering and then milling. Compared with the prior art, the nodules 21 can be removed more cleanly, the removal efficiency of the nodules 21 on the surface of the metal plate can be improved, and further the repeated short-circuit rate of the electrolytic cell can be reduced. Moreover, when processing the product electrolytic copper into the finished product warehouse, the grade of the product can be improved.

[0067] In some embodiments of the present invention, such as Figure 1As shown, the nodule removal device 100 may further include: a longitudinal guide rail 41, a support frame 40, and a traveling trolley 42. The support frame 40 is movably arranged on the longitudinal guide rail 41, and the support frame 40 can move along the length direction of the longitudinal guide rail 41. The traveling trolley 42 is movably arranged on the support frame 40, and the traveling trolley 42 can move along the length direction of the support frame 40. The traveling trolley 42 may be provided with a moving platform 30, and the short-circuit detection unit 31, the plate transfer unit 32, the nodule removal unit 33, and the nodule image recognition unit 34 may all be arranged on the moving platform 30. Through the cooperation of the longitudinal guide rail 41, the support frame 40, and the traveling trolley 42, the moving platform 30 can be transported above the electrolytic cell 22, facilitating the short-circuit detection of the cathode plate 24 in the electrolytic cell 22 by the nodule removal device 100.

[0068] In some embodiments of the present invention, the traveling trolley 42 may be provided with a vertical guide rail, and the moving platform 30 can move along the extending direction of the vertical guide rail. It can also be interpreted that the moving platform 30 can move on the traveling trolley through the vertical guide rail. Such a setting can expand the moving range of the moving platform 30. In the height direction, the spacing distance between the moving platform 30 and the electrolytic cell 22 can be adjusted, facilitating the cooperation of the short-circuit detection unit 31, the plate transfer unit 32, the nodule removal unit, and the nodule image recognition unit 34 to complete the removal of nodules on the short-circuited cathode plate 24.

[0069] It should be noted that both the nodule removal unit 33 and the nodule image recognition unit 34 are arranged within the reach of the plate transfer unit 32. The infrared imager is installed on the upper part of the moving platform 30, and the electromagnetic induction meter or the reed switch is installed on the lower part of the moving platform 30, capable of accurately positioning the short-circuited cathode plate 24 above the plate.

[0070] According to the nodule removal method for the cathode of the embodiment of the present invention, this nodule removal method can be applied to the above nodule removal device. The nodule removal method includes the following steps:

[0071] S101, determining the precise position of the short-circuited cathode in the electrolytic cell by analyzing the temperature data and / or magnetic field intensity data of the cathode in the electrolytic cell. It should be noted that the cathode can be a cathode plate, and the short-circuited cathode plate in the electrolytic cell can be detected by the short-circuit detection unit.

[0072] S102, automatically taking out the short-circuited cathode from the electrolytic cell. It should be noted that the short-circuited cathode can be taken out from the electrolytic cell by the plate transfer unit.

[0073] S103, automatically removing the nodules on the surface of the short-circuited cathode by the nodule removal unit.

[0074] S104. Automatically place the cathode with the removed complete grains back into the electrolytic cell. It should be noted that the cathode with the removed complete grains can be placed back into the electrolytic cell through the plate transfer unit.

[0075] In the related art, there are the following several ways to detect the short circuit of the cathode plate in the electrolytic cell: First, manually hold a drag meter and move it above the plate, repeatedly detecting back and forth. If a short-circuited cathode plate is detected, the drag meter will alarm, and then the short-circuited cathode plate will be extracted manually or by a crane, and the short-circuit grains will be removed with a flat shovel; Second, manually hold a water pipe and spray water on the conductive rod of the cathode plate, and then observe the water vapor evaporation situation after a period of time. The position where a large amount of fog is generated is considered to have a short-circuit plate, and then the short-circuited cathode plate will be extracted manually or by a crane, and the short-circuit grains will be removed with a flat shovel.

[0076] The current methods for detecting plate short circuits and removing grains have the following deficiencies: 1. Manual operation has a large labor intensity, low efficiency, and a poor working environment; 2. It is impossible to detect and handle short-circuit plates in a timely manner, with poor timeliness, and it cannot guarantee the current efficiency, product grade rate, and electrolysis stability of electrolysis operations; 3. Manual operation relies on experience, with low accuracy in short-circuit detection, difficult to guarantee reliability, low positioning accuracy, and low automation level.

[0077] In this application, the short-circuit detection unit, plate transfer unit, and grain removal unit can all be connected to the controller. By using the short-circuit detection unit to detect the short circuit of the cathode plate in the electrolytic cell, the position of the short-circuited cathode plate in the electrolytic cell can be detected, and the short-circuited cathode plate can be accurately positioned. Then the short-circuit detection unit transmits the position information of the short-circuited cathode plate to the controller, and the controller will control the plate transfer unit to take out the short-circuited cathode plate from the electrolytic cell and place it at the grain removal unit. Then the controller controls the grain removal unit to remove the grains (grain substances) on the surface of the short-circuited cathode plate. After the grain substances on the surface of the short-circuited cathode plate are removed, the controller will control the plate transfer unit to place the cathode plate with the removed grains back into the electrolytic cell. Such a setting can achieve accurate detection and positioning of the short-circuited cathode plate first, and then remove the grains on the surface of the cathode plate. Compared with the prior art, it is beneficial to improve the current efficiency and product grade rate of electrolysis operations, does not require operators to manually remove grains, can reduce the labor intensity of operators, can improve the grain removal efficiency, and can timely and accurately find the position of the short-circuited cathode plate, increasing the reliability of short-circuit detection. At the same time, this grain removal method is realized by intelligent control.

[0078] Thus, through the cooperation of the above steps, it is possible to first accurately detect and locate the short-circuited cathode plate, and then remove the nodules on the surface of the cathode plate, which is beneficial to improving the current efficiency and product grade rate of the electrolysis operation. Moreover, there is no need for operators to manually remove the nodules, which can reduce the labor intensity of the operators and improve the nodule removal efficiency.

[0079] In some embodiments of the present invention, detecting a short-circuited cathode plate in an electrolytic cell may include: determining the exact position of the short-circuited cathode plate in the electrolytic cell by analyzing the temperature data and / or magnetic field intensity data of the short-circuited cathode plate. It should be noted that the short-circuit detection unit can analyze the temperature data and / or magnetic field intensity data of the short-circuited cathode plate to determine the exact position of the short-circuited cathode plate in the electrolytic cell. Compared with the prior art, such a setting can more accurately detect the position of the short-circuited cathode plate, improving the accuracy of short-circuit detection. And the intelligent operation saves operation time and improves the detection efficiency.

[0080] In some embodiments of the present invention, removing the short-circuited cathode plate from the electrolytic cell may include: obtaining the actual data information of the nodules on the cathode surface, and then grasping the short-circuited cathode plate and taking it out of the electrolytic cell and placing it at a cleaning position. The cleaning position can be set on the nodule removal unit. Moreover, obtaining the actual data information of the nodules on the cathode plate surface, the actual data information includes the position and size of the nodules. It should be explained that after detecting the short-circuited cathode plate, when taking out the cathode plate from the electrolytic cell and placing it at the cleaning position for removing nodules, the nodule image recognition unit obtains the actual data information of the nodules on the cathode plate surface. The actual data information may include: the position and size of the nodules. Such a setting can achieve the working purpose of placing the cathode plate at the cleaning position for removing nodules, and can also achieve the working purpose of detecting the position and size of the nodules.

[0081] In some embodiments of the present invention, automatically removing a short-circuited cathode plate from the electrolytic cell may further include: setting preset data information. If the actual data information of the agglomeration does not fall within the preset data information, the plate transfer unit returns the short-circuited cathode plate to the electrolytic cell. If the actual data information of the agglomeration falls within the preset data information, the signal processing unit plans a path for removing the agglomeration on the surface of the cathode plate according to the actual data information, and then the controller controls the agglomeration removal unit to remove the agglomeration on the surface of the cathode plate according to the path for removing the agglomeration on the surface of the cathode plate. It should be noted that the preset data information of the agglomeration is set in the agglomeration image recognition unit. When the agglomeration image recognition unit detects the actual data information of the agglomeration on the surface of the cathode plate, the actual data information is sent to the signal processing unit. The signal processing unit can calculate the position and size of the agglomeration, and then the signal processing unit plans a path for removing the agglomeration on the surface of the cathode plate according to the actual data information, and then the controller controls the agglomeration removal unit to remove the agglomeration on the surface of the cathode plate according to the path for removing the agglomeration on the surface of the cathode plate. Such a setting can facilitate the removal of the agglomerates on the surface of the cathode plate and improve the removal efficiency of the agglomerates.

[0082] In some embodiments of the present invention, automatically returning the cathode plate with the agglomeration removed to the electrolytic cell may include: the plate transfer unit grabs the cathode plate with the agglomeration removed, and the plate transfer unit places the cathode plate with the agglomeration removed at the initial position in the electrolytic cell. Such a setting can return the cathode plate to the electrolytic cell for continuous electrolysis, thereby ensuring the current efficiency, product grade rate and electrolysis stability of the electrolysis operation.

[0083] In some embodiments of the present invention, before determining the exact position of the short-circuited cathode plate in the electrolytic cell by analyzing the temperature data and / or magnetic field intensity data of the cathode plate in the electrolytic cell, determine the position of the electrolytic cell where short-circuit detection and agglomeration removal are required. Such a setting can accurately and reliably find the electrolytic cell where short-circuit detection and agglomeration removal are required, shorten the time for detecting the position of the short-circuited cathode plate, improve the working efficiency of short-circuit detection, and also avoid the problem that the short-circuited cathode plate cannot be detected due to incorrect placement.

[0084] Specifically, the agglomeration removal method includes the following steps:

[0085] S1, the walking trolley runs the agglomeration removal device to the electrolytic cell where short-circuit plate detection and agglomeration removal are required, and the short-circuit detection unit performs a quick short-circuit detection on at least one electrolytic cell;

[0086] S2, the short - circuit detection unit detects the temperature data and / or magnetic field intensity data of the electrode plates in the electrolytic cell. The short - circuit detection unit analyzes and determines the exact position of the short - circuited electrode plates in the electrolytic cell, and transmits the data to the signal processing unit. The signal processing unit can calculate the position and size of the nodules, and then the signal processing unit plans a path to remove the nodules on the surface of the cathode plate according to the actual data information. Then, the controller controls the nodule removal unit to remove the nodules on the surface of the cathode plate according to the path of removing the nodules on the surface of the cathode plate;

[0087] S3, the controller controls the electrode plate transfer unit to grasp the detected short - circuited cathode plate and place the cathode plate on the nodule removal unit;

[0088] S4, the controller controls the nodule removal unit to start the cutter head according to the path of removing the nodules on the surface of the cathode plate, and removes the nodules on the surface of the cathode plate;

[0089] S5, after the nodules on the surface of the cathode plate are removed, the controller controls the electrode plate transfer unit to grasp the processed cathode plate from the nodule removal unit and then place the cathode plate back to the initial position in the electrolytic cell.

[0090] In some embodiments of the present invention, a programmable logic controller is used to implement the above - mentioned method for removing nodules on the cathode. When the nodule removal program is executed by the programmable logic controller, it can implement the method for removing nodules on the cathode plate as described in the above - mentioned embodiments, so that it can first accurately detect and locate the short - circuited cathode plate, and then remove the nodules on the surface of the cathode plate, which is beneficial to improving the current efficiency and product grade rate of the electrolysis operation. Moreover, it does not require operators to manually remove the nodules, which can reduce the labor intensity of the operators and improve the nodule removal efficiency.
