Description

[0002] Titanium anode plate is made of corrosion-resistant titanium plate as the base, and a layer of precious metal oxide is coated on the surface as the electrocatalytic active substance. During the use of titanium anode plate for electrolytic copper foil, a dense scaling layer will be covered on the surface. Due to the coverage of the scaling layer, the potential distribution of the anode plate becomes uneven, so the anode plate needs to be cleaned and maintained regularly to remove the scaling layer; at the same time, titanium anode plate fails during use due to coating shedding, surface passivation and other reasons. The coating bonding of the failed anode plate is poor, which affects the uniformity of the electrolysis effect.

[0003] During the flushing process of failed anode plates, the loss of coating should be avoided, which may easily cause the leakage of a large amount of lead-containing wastewater and waste residue, seriously polluting the environment.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer and more understandable, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0025] Titanium anode plate is made of corrosion-resistant titanium plate as the base, and a layer of precious metal oxide is coated on the surface as the electrocatalytic active substance. During the use of titanium anode plate for electrolytic copper foil, a dense scaling layer will be covered on the surface. Due to the coverage of the scaling layer, the potential distribution of the anode plate becomes uneven, so the anode plate needs to be cleaned and maintained regularly to remove the scaling layer; at the same time, titanium anode plate fails during use due to coating shedding, surface passivation and other reasons. The coating bonding of the failed anode plate is poor, which affects the uniformity of the electrolysis effect.

[0026] During the flushing process of failed anode plates, the loss of coating should be avoided, which may easily cause the leakage of a large amount of lead-containing wastewater and waste residue, seriously polluting the environment. Therefore, this part of the coating should be collected as much as possible to reduce the loss of precious metals. This is also of great significance to reducing the preparation cost of titanium anode plates.

[0027] An automatic cleaning system for titanium anode plates for electrolytic copper foil is disclosed, which includes a movable carrier for clamping the titanium anode plates to be cleaned, a cleaning device for cleaning the titanium anode plates, a settling tank provided with multiple isolation devices, and a reflux pump pipe connected to the last settling tank, and the other end of the reflux pump pipe is connected to the cleaning device to provide cleaning water. The cleaning system is for horizontally placing the titanium anode plates for cleaning, and in order to flush away the residue after cleaning, the flushing intensity is large and the flushing time is long, which causes more serious damage to the titanium anode plates, and increases the manufacturing and repair costs of the titanium anode plates.

[0028] The present invention provides a coating collection device 100, which is used for collecting coatings during the washing process of titanium anode plates.

[0029] like Figures 1 to 4 As shown, in order to achieve the above-mentioned purpose, the present invention provides a coating collection device 100, referring to Figure 1 The coating collection device 100 includes a frame 10 with a cavity 10A, a first placement mechanism 30 and a second placement mechanism 50 arranged in the cavity 10A and located above the bottom of the cavity 10A, the first placement mechanism 30 and the second placement mechanism 50 are used to fix titanium anode plates of different thicknesses, the first placement mechanism 30 and the second placement mechanism 50 are suspended and upright, and at least one of them is used; the bottom of the cavity 10A is used to collect cleaning wastewater and fallen coatings.

[0030] The coating collection device 100 proposed in the present invention is used for collecting coatings during the flushing process of titanium anode plates, and includes a frame 10 having a cavity 10A, a first placement mechanism 30 and a second placement mechanism 50 arranged in the cavity 10A. The bottom of the cavity 10A of the coating collection device 100 is used to accommodate and collect cleaning wastewater and fallen coatings. The first placement mechanism 30 and the second placement mechanism 50 are used to fix titanium anode plates of different thicknesses, and the two are suspended and placed upright and at least one of them can be used. The suspended upright setting can effectively reduce the amount of water used to flush the residue on the surface of the titanium anode plate, reduce the flushing intensity, and shorten the flushing time. It can not only reduce the damage to the titanium anode plate, but also reduce the production and repair costs of the flushed titanium anode plate. At the same time, at least one of the two can be used so that the flushing of the titanium anode plate can be set on demand according to the quantity requirements and thickness specification requirements, thereby improving the flexibility of use and flushing efficiency of the coating collection device 100.

[0031] It should be noted that the coating falls off during the flushing process of the titanium anode plate, and the coating contains precious metals. The coating collection device 100 of the present invention collects the coating at the bottom of the cavity 10A, thereby avoiding the loss of precious metals during the flushing process of the titanium anode plate containing the precious metal coating. The setting of the first placement mechanism 30 and the second placement mechanism 50 can be applied to the flushing of titanium anode plates of different thicknesses, different sizes, and different types.

[0032] Optionally, the frame 10 is made of one of corrosion-resistant PP, PPH, and PTFE, which is low-cost, corrosion-resistant, and has a long service life.

[0033] Furthermore, the first prevention and control mechanism 30 and the second placement mechanism 50 can be made of one of the corrosion-resistant PP, PPH, and PTFE materials that are the same as the frame 10, so that the whole machine has low cost, corrosion resistance, long service life, and can be cast in an integrated manner.

[0034] Combined with reference Figure 1 and Figure 3 As shown, optionally, the frame 10 includes a bottom plate 11, a front plate 12 and a back plate 13 arranged in front and behind the bottom plate 11, and two side plates 14 arranged at intervals on the left and right sides of the bottom plate 11. The bottom plate 11, the front plate 12, the back plate 13 and the two side plates 14 enclose an open cavity 10A, one end of the first placement mechanism 30 is arranged on the front plate 12, and the other end is arranged on the back plate 13, the top edge of the front plate 12 is lower than the top edge of the back plate 13, and a second placement mechanism 50 is provided on at least one side plate 14.

[0035] In this embodiment, the top edge of the front plate 12 is lower than the top edge of the back plate 13 so that the cavity 10A has a large-section opening. The cavity 10A with a large-section opening provides sufficient space for the titanium anode plate to be placed in the first placement mechanism 30 and the second placement mechanism 50, thereby improving the convenience of placement and taking.

[0036] A second placement mechanism 50 is provided on at least one side plate 14, that is, the number of second placement mechanisms 50 is at least one group, that is to say, there can be two groups, that is, second placement mechanisms 50 are respectively provided on the side plates 14 on both sides, and at the same time, a titanium anode plate can be placed on the first placement mechanism 30, so that the coating collection device 100 can perform flushing operations on up to three titanium anode plates at a time, thereby improving the flushing efficiency.

[0037] Combined with reference Figure 1 and Figure 2 As shown, optionally, the first placement mechanism 30 includes a first bracket 31 and a second bracket 32 ​​, the first bracket 31 is disposed on the front plate 12 , the second bracket 32 ​​is disposed on the back plate 13 , and the second bracket 32 ​​is disposed at a higher height than the first bracket 31 .

[0038] In this embodiment, the first bracket 31 is arranged on the front plate 12, and the second bracket 32 ​​is arranged on the back plate 13. The setting height of the second bracket 32 ​​is higher than that of the first bracket 31, and the length of the connection line between the first bracket 31 and the second bracket 32 ​​is less than or equal to the length of the titanium anode plate, so that the titanium anode plate can be abutted against the first bracket 31 at one end, and the other end just abuts against or exceeds the second bracket 32. The second bracket 32 ​​supports or limits the titanium anode plate, so that the titanium anode plate can be obliquely erected in the cavity 10A, which improves the convenience of flushing, can appropriately reduce the flushing intensity, reduce the water consumption of flushing, and save water resources.

[0039] Furthermore, the first bracket 31 and the second bracket 32 ​​are arranged in a raised shape on the front plate 12 and the back plate 13, and the first bracket 31 is provided with an anti-scratch portion on at least the upper surface and the raised end surface facing the second bracket 32. Similarly, the second bracket 32 ​​is provided with an anti-scratch portion on at least the lower surface and the raised end surface facing the first bracket 31. Exemplarily, the anti-scratch portion is a rubber protective cover, a silicone protective cover or a soft cover made of other elastic materials to protect the titanium anode plate from scratches.

[0040] Furthermore, the length of the first bracket 31 is greater than the length of the second bracket 32, wherein the length of the first bracket 31 allows one end of the titanium anode plate to be disposed within the enclosed angle between the first bracket 31 and the front plate 12, thereby improving the stability of the bottom arrangement of the titanium anode plate. The raised end of the second bracket 32 ​​is a smooth transition, thereby reducing the push damage to the titanium anode plate by the outer periphery of the second bracket 32, thereby protecting the titanium anode plate.

[0041] Optionally, at least one group of second brackets 32 is provided, and a plurality of groups of second brackets 32 are arranged on the back plate 13 at intervals along high and low directions.

[0042] In this embodiment, the first bracket 31 can be set as a group, the first bracket 31 is set on the side of the front plate 12 facing the cavity 10A and adjacent to the top of the front plate 12, and the second bracket 32 ​​can be set as at least one group. When the second bracket 32 ​​is set as a group, the second bracket 32 ​​can be adjusted in height along the upper and lower positions of the back plate 13 to adapt to the placement of titanium anode plates of different lengths. In another case, the second bracket 32 ​​is set as at least two groups, that is, it can be set as two or more groups, and the multiple groups of second brackets 32 are arranged on the back plate 13 at intervals along the high and low positions to adapt to the placement of titanium anode plates of different lengths.

[0043] Furthermore, the first bracket 31 can be set as a bracket bar or multiple bracket members. When multiple bracket members are set, multiple bracket members are horizontally spaced to form a group of first brackets 31, which can reduce the cost of the first bracket 31 and increase the support points of the titanium anode plate, thereby improving the placement reliability of the titanium anode plate. The setting of the second bracket 32 ​​is similar to that of the first bracket 31. The two can be set in the same type or in a free combination of different types.

[0044] It can be understood that the cooperation between the first bracket 31 and the second bracket 32 ​​of the first placement mechanism 30 can tilt and place the titanium anode plate upright, so that its supporting capacity is stronger. The first placement mechanism 30 can be used for supporting and positioning thick titanium anode plates that are not easy to deform, and can also be used for supporting and positioning titanium anode plates containing studs. The second placement mechanism 50 can be used for supporting and positioning thin titanium anode plates that are easy to deform.

[0045] Combined with reference Figures 1 to 3 As shown, optionally, the second placement mechanism 50 includes a first slot plate 51 and a second slot plate 52, and the first slot plate 51 and the second slot plate 52 are arranged on the side plate 14 at intervals along a high and low orientation, and the first slot plate 51 and the second slot plate 52 can be relatively displaced.

[0046] In the present embodiment, at least one of the first slot plate 51 and the second slot plate 52 can be relatively close to or away from the other, that is, the first slot plate 51 and the second slot plate 52 are movably matched and the titanium anode plate can be fixed to the side plate 14, so as to perform a flushing operation, wherein the titanium anode plate is arranged almost parallel to the side plate 14, so that the side plate 14 can reliably support the thinner and more easily deformable titanium anode plate, thereby avoiding deformation caused by excessive water pressure during the flushing process.

[0047] Furthermore, the first slot plate 51 can be set to be fixed and the second slot plate 52 can be movable, or the second slot plate 52 can be set to be fixed and the first slot plate 51 can be movable. Since the first slot plate 51 is arranged near the bottom of the cavity 10A, it is preferred to set the first slot plate 51 located at a lower position to be fixed and the second slot plate 52 located at a higher position to be movable, and the movable direction is to move in the vertical direction or approach the first slot plate 51, so that the cooperation between the first slot plate 51 and the second slot plate 52 can adapt to the support and positioning of titanium anode plates of different sizes, thereby improving the versatility of the second placement mechanism 50.

[0048] Optionally, the second slot plate 52 is spaced apart from the first slot plate 51 in the upper and lower directions. The first slot plate 51 is provided with an upper slot 51A, and the second slot plate 52 is provided with a lower slot 52A. The upper slot 51A and the lower slot 52A are arranged opposite to each other, and at least the first slot plate 51 is provided with a water hole.

[0049] In this embodiment, the first slot plate 51 and the second slot plate 52 support and position the titanium anode plate by means of a slot. Specifically, the first slot plate 51 is provided with an upper slot 51A, and the second slot plate 52 is provided with a lower slot 52A. Among them, the first slot plate 51 and the second slot plate 52 are both L-shaped plates, and the first slot plate 51 and the second slot plate 52 are respectively matched with the side plate 14 to form an upper slot 51A and a lower slot 52A both of which are U-shaped slots. The upper slot 51A and the lower slot 52A are arranged opposite to each other, and the two ends of the titanium anode plate are respectively inserted into the upper slot 51A and the lower slot 52A for support and positioning, so as to perform the flushing operation.

[0050] At least the first slot plate 51 is provided with a water hole. The first slot plate 51 is located at a lower part of the side plate 14. At least one water hole or multiple water holes are opened on the first slot plate 51, so that the waste water and coating residue after flushing can quickly flow out of the slot of the lower slot 52A to enter the cavity 10A, thereby preventing the bottom of the titanium anode plate from being soaked in water and improving the convenience of flushing.

[0051] Furthermore, the first slot plate 51 can be set as a slot bar or multiple slot parts. When multiple slot parts are set, multiple slot parts are horizontally spaced to form a group of first slot plates 51, which can not only reduce the cost of the first slot plate 51, but also increase the support points of the titanium anode plate, improve the placement reliability of the titanium anode plate, and also facilitate the discharge of wastewater and coating residues. The setting of the second slot plate 52 is similar to that of the first slot plate 51. The two can be set in the same type or in a free combination of different types.

[0052] Combined with reference Figure 1 , Figure 3As shown, optionally, the side panel 14 is provided with at least two slide grooves 14A extending in the height direction, and the second placement mechanism 50 also includes a sliding plate 53, which is arranged on the side of the back panel 13 facing away from the first slot plate 51 and the second slot plate 52, and the sliding plate 53 is provided with a connecting portion corresponding to the slide groove 14A, and the connecting portion passes through the slide groove 14A to connect the first slot plate 51 or the second slot plate 52.

[0053] In this embodiment, a handle is provided on the side of the sliding plate 53 facing away from the side plate 14, and the sliding plate 53 can be moved up and down by holding the handle, thereby adjusting the relative height of the first slot plate 51 or the second slot plate 52, so that the cooperation between the first slot plate 51 and the second slot plate 52 can adapt to the support positioning of titanium anode plates of different sizes.

[0054] The number of sliding plates 53 can be one or two, that is, the first slot plate 51 and the second slot plate 52 can be equipped with a sliding plate 53 separately, or they can be equipped with sliding plates 53 respectively. It is preferred to set the first slot plate 51 to a fixed position, and equip the second slot plate 52 with a sliding plate 53, so as to achieve adaptive support and positioning of titanium anode plates of different sizes by adjusting the position of the second slot plate 52, thereby improving the versatility of the second placement mechanism 50.

[0055] Combined with reference Figure 1 and Figure 3 As shown, optionally, the coating collection device 100 further includes a filter valve 60 and a drain valve 70 communicating with the chamber 10A, and the filter valve 60 and the drain valve 70 are arranged on the same side or two adjacent sides of the frame 10 .

[0056] In this embodiment, the bottom of the cavity 10A is used to accommodate and collect the waste water and the coating residues that have fallen off after flushing. The coating collection device 100 is provided with a filter valve 60 and a drain valve 70 at the corresponding waste water and coating residue accommodation and collection location. The filter valve 60 is used to filter solid residues, that is, filter the coating residues that have fallen off; the drain valve 70 is used to drain the sewage. The filter valve 60 and the drain valve 70 are arranged on the same side or adjacent sides of the frame 10. For example, the filter valve 60 and the drain valve 70 can both be arranged on the front plate 12 or the bottom plate 11, or one can be arranged on the front plate 12 and the other can be arranged on the bottom plate 11, so as to filter the coating residues that have fallen off so that they can be collected separately, and avoid the coating residues containing heavy metals from being discharged to pollute the environment.

[0057] Optionally, the filter valve 60 is arranged flush with the drain valve 70 , or the drain valve 70 is arranged higher than the filter valve 60 .

[0058] In this embodiment, the filter valve 60 and the drain valve 70 can be opened separately or simultaneously, so that the filter valve 60 and the drain valve 70 can be set flush, or the drain valve 70 can be set higher than the filter valve 60. The waste water is first discharged through the drain valve 70, and then the water in the coating residue precipitated at the bottom layer of the cavity 10A is discharged through the filter valve 60, and then the residue is collected. This is carried out in steps to avoid leakage of the residue as much as possible.

[0059] Combination Figure 1 , Figure 3 as well as Figure 4 As shown, optionally, the frame 10 is provided with a filter hole corresponding to the filter valve 60, and the coating collection device 100 further includes a first filter cloth 63, and the first filter cloth 63 is covered at the filter hole.

[0062] The frame 10 is provided with a drain hole corresponding to the drain valve 70. In one embodiment, the drain valve 70 can be arranged on the outside of the frame 10, and one end of the drain valve 70 is connected to the drain hole, the drain valve 70 is arranged at the drain hole and the second filter cloth 73 is covered at the drain hole; in another embodiment, the drain valve 70 is penetrated in the drain hole, and one end of the drain valve 70 located in the cavity 10A is provided with a threaded hole with a second external thread 71 and a second matching nut 72 for fixing the second filter cloth 73, combined with reference Figure 4 Both embodiments can achieve that the waste water flowing back into the chamber 10A after flushing is discharged in large quantities and as much as possible.

[0063] Furthermore, a push-pull portion 80 is disposed on the outer side of the frame 10 of the coating collection device 100 to facilitate moving the device.

[0064] The working principle of the coating collection device 100 provided by the present invention is as follows:

[0065] First, the user selects a fixed position according to the thickness of the titanium anode plate. The thick titanium anode plate that is not easily deformed is placed obliquely on the first bracket 31 and the slidable second bracket 32 ​​according to the length of the plate, or placed on the first bracket 31 and another second bracket 32, and the other second bracket 32 ​​can be temporarily defined as the third bracket 33; the thin titanium anode plate that is easily deformed is placed vertically in the first slot plate 51 and the second slot plate 52. Then the user rinses the titanium anode plate with a high-pressure water gun. When the water level of the collection tank is close to the first bracket 31, the drain valve 70 is opened, and the wastewater without solid residue is discharged after filtering through the second filter cloth 73. The coating residue precipitated at the bottom of the cavity 10A appears as solid residue, and after accumulating a certain thickness, the filter valve 60 is opened, and the wastewater remaining in the solid residue is filtered out through the first filter cloth 63, and the precipitated solid residue is collected, thereby avoiding the loss of precious metals during the flushing of the titanium anode plate containing precious metal coatings. It is an ideal device for reducing the loss of precious metals in the preparation process of precious metal titanium anode plates.
