Description

Technical Field

[0001] The invention belongs to the technical field of chemical industry, and in particular relates to a secondary washing device for electrolytically refined metal plates. Background Art

[0002] Hydrometallurgy is a common method for metal purification. For example, in the copper electrolytic refining process using permanent stainless steel cathode plates, obtaining qualified copper requires washing the copper deposited on the cathode plate surface to remove impurities such as residual electrolyte. Existing methods often only incorporate a primary washing device to clean the copper adhering to the cathode plate surface. This results in poor cleaning effectiveness, and residual electrolyte on the copper plate surface can affect the quality of the finished copper.

[0003] For example, a Chinese utility model patent discloses a cathode stripping machine unit [application number: 201620902768.2], which includes: a first washing device; a stripping device; a cathode plate input device; a cathode plate output device; a conveying device for conveying cathode plates, wherein the conveying direction of the conveying device is parallel to the plate surface of the cathode plate, and the cathode plate input device, the first washing device, the stripping device and the cathode plate output device are arranged in sequence along the conveying direction of the conveying device.

[0004] When the utility model patent uses the first washing device to clean the electrolytic copper, the electrolytic copper is still attached to the cathode plate, so this cleaning method cannot clean the electrolyte remaining in the cathode plate clamping strip, which will cause the surface of the electrolytic copper after stripping to contain residual electrolyte. Therefore, it is necessary to provide a device to re-wash the inside of the electrolytic copper after stripping. Summary of the Invention

[0033] According to the present invention, when in use, the cathode plate with the metal plate attached thereto is conveyed by the conveying mechanism 1 to the first washing device 7, the first washing device 7 performs preliminary cleaning on the metal plate, and after preliminary cleaning, the metal plate is transferred by the conveying mechanism 1 to the stripping system 8 for stripping, so that the metal plate and the cathode plate are separated, and the stripped metal plate is placed on the conveying mechanism 1 and conveyed to the second washing device 9 by the conveying mechanism 1 for secondary washing. Therefore, the present invention is provided with the first washing device 7 and the second washing device 9 in sequence along the conveying direction of the conveying mechanism 1, which can respectively perform preliminary washing on the metal plate and secondary washing on the stripped metal plate, thereby completely removing the electrolyte remaining on the inner surface of the metal plate and ensuring product quality.

[0034] Specifically, the conveying mechanism 1 includes a first conveying section 11, a second conveying section 12 and a third conveying section 13; the metal plate attached to the cathode plate is vertically conveyed on the first conveying section 11 and the first washing device 7 at least cleans the outer side of the metal plate; the metal plate after stripping the surface of the cathode plate is conveyed flat on the third conveying section 13 and the second washing device 9 at least cleans the stripping surface of the metal plate. When in use, the metal plate attached to the surface of the cathode plate is first conveyed through the first conveying section 11, and passes through the first washing device 7 during the conveying process, so that the outer side of the metal plate is washed. After being stripped by the stripping system 8, the metal plate lies flat on the third conveying section 13, conveyed through the third conveying section 13, and passes through the second washing device 9 during the conveying process. The second washing device 9 washes the stripping surface of the metal plate, that is, the side attached to the cathode plate before stripping, thereby achieving the purpose of washing both sides of the metal plate and completely removing the electrolyte remaining on the inner surface of the metal plate.

[0035] Combine Figure 3 and Figure 4 As shown, the second washing device 9 includes a washing chamber 2 and a washing liquid supply mechanism 4 that are interconnected, and a pipeline system 5 is provided between the washing chamber 2 and the washing liquid supply mechanism 4.

[0036] During use, the metal plate to be washed is transported to the washing chamber 2, and the washing liquid supply mechanism 4 transports the washing liquid heated by the heating component 6 to the washing chamber 2 through the pipeline system 5 and washes the metal plate. Therefore, the invention is provided with a heating component 6 that can heat the washing liquid. In this way, the metal plate can be washed with washing liquid with a certain temperature during the washing process, which helps to clean the stains on the surface of the metal plate and has a better washing effect.

[0037] Combine Figure 3 and Figure 4As shown, the washing liquid supply mechanism 4 includes a washing liquid storage tank 41 with a storage cavity 42 inside, the piping system 5 is connected to the storage cavity 42, the upper section of the washing liquid storage tank 41 is connected to a washing liquid supply pipe 43 connected to the storage cavity 42, and the washing liquid can be replenished into the storage cavity 42 through the washing liquid supply pipe 43, and the lower section of the washing liquid storage tank 41 is connected to a drain pipe 44 connected to the storage cavity 42. After washing a certain number of times, when the washing liquid needs to be replaced as a whole, the washing liquid in the storage cavity 42 can be discharged as a whole through the drain pipe 44.

[0038] Preferably, an overflow port 45 communicating with the storage cavity 42 is provided on the top of the washing liquid storage tank 41 , and excess washing liquid or washing liquid steam can overflow through the overflow port 45 , thereby preventing the pressure in the storage cavity 42 from being too high.

[0040] Preferably, the heating component 6 also includes a liquid level gauge 62 and a temperature sensor 63 arranged in the storage cavity 42. The liquid level gauge 62 can detect the liquid level of the washing liquid in the storage cavity 42. After reaching a certain liquid level, the steam valve is controlled to allow steam to circulate in the steam pipe 61 to exchange heat and heat the washing liquid. The temperature sensor 63 can detect the temperature of the washing liquid in the storage cavity 42 and control the steam valve to ensure that the temperature of the washing liquid in the storage cavity 42 is within an appropriate range. The liquid level gauge 62 and the temperature sensor 63 can both be specific devices in the existing technology that can realize the corresponding functions.

[0041] Combine Figure 3 and Figure 4 As shown, the piping system 5 includes an infusion pipe 51 for transporting clean washing liquid into the washing chamber 2 and a reflux pipe 52 for returning the washed washing liquid to the washing liquid supply mechanism 4.

[0042] Combine Figure 4 and Figure 5As shown, the washing chamber 2 includes a shell 21 with a washing cavity 27 inside. The shell 21 can make the space for washing relatively closed to prevent the acid mist generated by washing from leaking out and causing a bad production environment. A blow-drying pipe 23 and a spray pipe 22 connected to the pipeline system 5 are provided in the shell 21. The spray pipe 22 and the blow-drying pipe 23 are both connected to the washing cavity 27. The spray pipe 22 is provided with at least one nozzle 25, and the blow-drying pipe 23 is provided with at least one air outlet pipe 24. The air outlet pipe 24 can spray high-pressure gas to increase the flow rate of the gas on the surface of the metal plate and promote the drying of the metal plate surface. The washing liquid after washing in the washing cavity 27 flows back to the washing liquid supply mechanism 4 through the pipeline system 5.

[0043] During use, the metal plate is transported to the washing chamber 27 in the shell 21 , and the washing liquid is sprayed from the nozzle 25 through the spray pipe 22 to wash the surface of the metal plate. The washed metal plate is blown dry by the air outlet pipe 24 .

In this way, during the washing and drying process, both sides of the metal plate can be washed and dried simultaneously.

[0045] Preferably, the spray pipe 22 is fixedly connected to the inner wall of the housing 21, and the angle between the nozzle extension direction of the nozzle head 25 and the vertical direction is 0-45 degrees, that is, the angle between the water outlet direction and the vertical direction is 0-45 degrees, more preferably 20 degrees. The drying pipe 23 is fixedly connected to the inner wall of the housing 21, and the angle between the outlet extension direction of the air outlet of the air outlet pipe 24 and the vertical direction is 0-45 degrees, that is, the angle between the air outlet direction and the vertical direction is 0-45 degrees, more preferably 20 degrees. This arrangement of the nozzle head 25 and the air outlet pipe 24 with a certain inclination angle can ensure the washing and drying effect on the metal plate while also increasing the washing or drying range of each nozzle head 25 and air outlet pipe 24.

[0046] Combine Figure 4 and Figure 5 As shown, the washing chamber 2 also includes an exhaust and demisting device 26 connected to the shell 21, and the exhaust and demisting device 26 is connected to the washing chamber 27. The exhaust and demisting device 26 can discharge the acid mist generated during washing into the exhaust system in time, further ensuring a better production environment. The exhaust and demisting device 26 can adopt the exhaust and demisting device recorded in the invention patent with application number "201010615253.1".

[0047] Combine Figure 6-8As shown, the conveying mechanism 1 is also provided with a stacking mechanism 3 that can stack the metal plates washed by the second washing device 9, and the stacking mechanism 3 includes a frame 31, and the frame 31 is provided with a sheet material grasping and placing mechanism 32, and the conveying mechanism 1 passes directly under the sheet material grasping and placing mechanism 32, and the sheet material grasping and placing mechanism 32 is connected to the transverse frame 34 through the lifting drive mechanism 33, and the transverse frame 34 is connected to the frame 31 through the transverse drive mechanism 35, and the central axis of the conveying mechanism 1 is parallel to the moving direction of the transverse frame 34.

[0048] During use, when the conveying mechanism 1 transports the metal plate to the bottom of the sheet material grabbing and releasing mechanism 32, the lifting drive mechanism 33 drives the sheet material grabbing and releasing mechanism 32 to descend, and the sheet material grabbing and releasing mechanism 32 grabs the metal plate and lifts it; when the next metal plate is transported to the bottom of the sheet material grabbing and releasing mechanism 32 by the conveying mechanism 1, the transverse drive mechanism 35 drives the transverse frame 34 to move a distance in the transmission direction of the conveying mechanism 1; when the next metal plate is transported to the bottom of the sheet material grabbing and releasing mechanism 32 by the conveying mechanism 1, the lifting drive mechanism 33 drives the sheet material grabbing and releasing mechanism 32 to the metal plate release position, and then the transverse drive mechanism 35 drives the transverse frame 34 to move in the opposite direction of the transmission direction of the conveying mechanism 1 to its original position. At this time, the sheet material grabbing and releasing mechanism 32 releases the metal plate, thereby pre-stacking the metal plate.

[0049] Specifically, the sheet material grasping and placing mechanism 32 includes a grasping and placing seat 321, on which is provided at least a pair of mutually opposed and parallel clamping plates 322, each clamping plate 322 being connected to a clamping driver 323, the extending direction of the clamping plates 322 being perpendicular to the moving direction of the clamping plates 322, and each clamping plate 322 being provided with an anti-drop mechanism 324; the anti-drop mechanism 324 includes a clamping plate 322 provided on one end thereof and facing the clamping plate 322 opposite thereto. The limiting hook 325 has an outer end with an inclined surface 326 extending outward from bottom to top, and the inclined surfaces 326 of the two opposing limiting hooks 325 are in an inverted eight-shaped shape. The setting of the inclined surface 326 can facilitate the clamping of the metal plate. The moving direction of the clamping plate 322 is parallel to the central axis of the conveying mechanism 1; the output shaft of the clamping driver 323 is swingably connected to the middle of the clamping plate 322, and a horizontal guide structure 327 is provided between the clamping plate 322 and the grab and release seat 321; the The cam 328 is fixed to the workbench 322 by the guide rail 329, and the cam 329 is fixed to the workbench 322 by the guide rail 329.

[0050] Specifically, the lifting drive mechanism 33 includes a lifting drive 331 provided on the transverse frame 34, the output shaft of the lifting drive 331 is swingably connected to the grab and release seat 321, and the lifting drive 331 drives the sheet metal grab and release mechanism 32 to switch between three positions: high, middle and low. When the sheet metal grab and release mechanism 32 is in the high position, the conveying mechanism 1 transmits the metal plate; when the sheet metal grab and release mechanism 32 is in the middle position, the sheet metal grab and release mechanism 32 places the metal plate; when the sheet metal grab and release mechanism 32 is in the low position, the sheet metal grab and release mechanism 32 grabs the metal plate. A vertical guide structure 332 is provided between the grab and release seat 321 and the transverse frame 34; the vertical guide structure 332 includes vertical guide slides 333 respectively arranged on both sides of the output shaft of the lifting drive 331, and the transverse frame 34 is provided with a vertical guide slide hole (not shown in the figure) corresponding to the vertical guide slide 333.

[0051] Specifically, the transverse drive mechanism 35 includes a transverse drive 351 fixed to the frame 31. The output shaft of the transverse drive 351 is pivotally connected to the transverse frame 34. A transverse guide structure 352 is provided between the transverse frame 34 and the frame 31. The transverse guide structure 352 includes at least one set of transverse rods 353 symmetrically arranged on either side of the transverse frame 34. Each transverse rod 353 has a roller 354 at its outer end. The frame 31 is provided with a roller groove 355 corresponding to the roller 354, and the roller 354 is seated in the roller groove 355. The transverse drive mechanism 35 can drive the transverse frame 34 to move forward and backward within a certain distance in a direction parallel to the conveying direction of the conveyor mechanism 1. In this way, even if the metal sheet stops at a slightly different position, the position of the transverse frame 34 can be adjusted to ensure that the sheet material grasping and releasing mechanism 32 can grasp or release the metal sheet in the vertical direction.

[0052] The working principle of the present invention is as follows: when in use, the cathode plate with the metal plate attached is transported by the conveying mechanism 1 to the first washing device 7, the first washing device 7 performs preliminary cleaning on the metal plate, and after preliminary cleaning, it is transferred by the conveying mechanism 1 to the stripping system 8 for stripping, so that the metal plate and the cathode plate are separated, and the stripped metal plate is placed on the conveying mechanism 1 and transported to the washing chamber 27 by the conveying mechanism 1. The washing liquid is transported to the washing liquid storage tank 41 through the washing liquid supply pipe 43. When it reaches a certain liquid level, the liquid level meter 62 controls the steam valve to open, and the high-temperature steam enters the steam pipe 61 and emits heat with the washing liquid. Heat exchange causes the washing liquid to heat up. When the metal plate is transported to the washing chamber 27 in the shell 21, the heated washing liquid is transported to the spray pipe 22 through the liquid delivery pipe 51. The washing liquid is sprayed from the nozzle 25 by the spray pipe 22 to wash the surface of the metal plate. The washed metal plate is blown dry by the air outlet pipe 24. The acid mist generated during the washing process is discharged into the exhaust system in time by the exhaust demisting device 26. The washing liquid after washing flows back through the return pipe 52, and flows back to the washing liquid storage tank 41 after being filtered through the filter screen 53. After washing a certain number of times, the washing liquid is discharged as a whole through the sewage pipe 44. The clean washing liquid is then injected through the washing liquid supply pipe 43, thereby realizing the replacement of the washing liquid. After the secondary washing is completed, when the conveying mechanism 1 transports the metal plate to the bottom of the sheet material grabbing and placing mechanism 32, the lifting drive mechanism 33 drives the sheet material grabbing and placing mechanism 32 to descend and the sheet material grabbing and placing mechanism 32 grabs the metal plate and lifts it; when the next metal plate is transported by the conveying mechanism 1 to the bottom of the sheet material grabbing and placing mechanism 32, the transverse drive mechanism 35 drives the transverse frame 34 to move a distance in the transmission direction of the conveying mechanism 1; when the next metal plate is transported by the conveying mechanism 1 to the bottom of the sheet material grabbing and placing mechanism 32, the transverse drive mechanism 35 drives the transverse frame 34 to move a distance in the transmission direction of the conveying mechanism 1; When the sheet material is directly below the release mechanism 32, the lifting drive mechanism 33 drives the sheet material grasping and placing mechanism 32 to descend to the metal plate release position, and then the transverse drive mechanism 35 drives the transverse frame 34 to move in the opposite direction of the transmission direction of the conveying mechanism 1 to the original position. At this time, the sheet material grasping and placing mechanism 32 releases the metal plate, thereby pre-stacking the metal plate. Therefore, the present invention is provided with a first washing device 7 and a second washing device 9 in sequence along the conveying direction of the conveying mechanism 1, which can respectively perform preliminary washing on the metal plate and secondary washing on the stripped metal plate, thereby completely removing the electrolyte remaining on the inner surface of the metal plate to ensure product quality.
