Description

Technical Field

[0001] The utility model relates to the technical field of electroplating, in particular to a waste liquid treatment device and an electroplating system. Background Art

[0002] Electroplating is a surface treatment technology that uses electrochemical principles to deposit a metal or alloy layer on the surface of a substrate. Through reasonable pre-treatment, electroplating process control and post-treatment, it can significantly improve the performance of the substrate and customize the surface function. It is widely used in many industrial fields.

[0003] In the prior art, in electroplating production, when the plate moves from tank A to tank B, the residual liquid medicine in tank A may flow into tank B along with the plate surface, causing the liquid medicine in tank B to be contaminated. In order to solve this problem, a set of water-blocking rollers is added between tank A and tank B to treat the residual liquid medicine on the plate surface. At the same time, two sets of water tanks are added between tank A and tank B to clean the residue on the plate surface that the rollers cannot handle. However, the washing liquid after cleaning contains a large amount of industrial liquid medicine. In order to ensure the cleanliness of the plate surface, it is necessary to continuously add new water to the water tank and discharge the waste liquid in the water tank, resulting in the need to consume a large amount of water resources in electroplating production and increase the cost of waste liquid treatment. Utility Model Content

[0004] In view of this, the utility model provides a waste liquid treatment device and an electroplating system to solve the problems of water resource consumption and waste liquid treatment cost in electroplating production.

[0005] In a first aspect, the utility model provides a waste liquid treatment device, comprising:

[0006] Install the frame;

[0007] A processing box is installed in the installation frame and is suitable for being immersed in the waste liquid, the processing box comprises a box body with a cavity and an opening opened at the top of the box body, at least one side of the box body is provided with a hollow hole and an ion membrane is covered at the hollow hole, the ion membrane is used to separate water molecules and acid ions in the waste liquid;

[0008] an anode plate, disposed in the cavity from the opening, suitable for introducing acid ions into the cavity;

[0009] The cathode plate is arranged in the waste liquid outside the processing box and is electrically connected to the anode plate.

[0010] Beneficial effect: This waste liquid treatment device sets the anode plate in the cavity of the treatment box from the opening, so that the anode plate contacts the waste liquid in the cavity, and sets the cathode plate in the waste liquid outside the treatment box. Since the cavity is connected to the waste liquid through the ion membrane, the cathode plate is electrically connected to the anode plate under the conductive effect of the waste liquid. The metal ions (such as copper, tin, nickel, etc.) in the waste liquid are reduced on the cathode plate by the action of electrolysis, and the acid radical ions in the waste liquid are reduced on the anode plate. Since the hollow holes of the box body are covered with an ion membrane, the ion membrane has selective permeability, allowing the acid radical ions to pass through and preventing water molecules from entering the cavity. Therefore, the acid radical ions generated during the electrolysis process can smoothly enter the cavity and concentrate under the attraction of the anode plate, and are effectively separated from the water molecules in the waste liquid. After the treatment is completed, it is only necessary to regularly collect the reduced metal ions from the cathode plate and take out the gathered acid radical ions from the cavity to achieve the extraction of metals and acid radical ions in the waste liquid. The separated waste liquid can be reused because the main pollutants are removed, thereby reducing the waste of water resources, reducing the amount of waste liquid discharged, and effectively saving the cost of waste liquid treatment.

[0011] In an optional embodiment, the ion membrane is provided on two opposite sides of the processing box.

[0012] Beneficial effect: Ion membranes are arranged on two opposite sides of the treatment box. Due to the attraction of the two sides of the anode plate to the acid ions in the waste liquid, the acid ions on both sides of the anode plate pass through the ion membranes on the corresponding sides and enter the cavity, which significantly increases the number of acid ions passing through the ion membrane per unit time, thereby increasing the rate of transfer of acid ions from the waste liquid to the cavity and enhancing the aggregation efficiency. At the same time, it helps to form a more uniform acid ion concentration distribution in the cavity, avoiding the phenomenon of excessively high or low local concentration caused by the ion membrane on one side, which is conducive to maintaining the stability of electrolysis and further improving the aggregation efficiency of acid ions.

[0013] In an optional embodiment, a drainage cavity communicating with the cavity is formed on the side of the processing box, and a drainage port is formed on the top of the drainage cavity.

[0014] Beneficial effect: After the waste liquid treatment is completed, since the drainage chamber is connected to the cavity, the waste liquid in the cavity will flow into the drainage chamber, and the waste liquid (aggregated acid ions) in the cavity can be discharged through the drain port at the top of the drainage chamber, so as to centrally collect the treated waste liquid and avoid the accumulation of treated waste liquid inside the equipment, affecting the normal operation of the equipment or causing secondary pollution.

[0015] In an optional embodiment, a connecting portion is provided on the anode plate, and the connecting portion extends out of the opening.

[0016] Beneficial effects: When the anode plate is installed in the cavity, the connection part of the anode plate extends out of the opening, so that the anode plate can be electrically connected to the external equipment through the connection part, simplifying the installation and removal process, saving operation time and labor costs. When the anode plate needs to be inspected, cleaned or replaced, the connection part extends out of the opening so that the operator can take out the anode plate without going deep into the cavity.

[0017] In an optional implementation, the anode plate is arranged in parallel with the cathode plate.

[0018] Beneficial effects: The anode plate and the cathode plate are arranged parallel to each other, so that the distance between the anode plate and the cathode plate is constant, thereby ensuring that the electric field is relatively evenly distributed on the surface of the cathode plate, which is conducive to the metal ions forming a uniform metal deposition layer on both sides of the cathode plate. At the same time, the anode plate and the cathode plate are arranged parallel to each other, so that multiple anode plates and cathode plates can be arranged in a specified space.

[0019] In an optional embodiment, the processing box and the cathode plate are both provided in plurality, and the plurality of processing boxes and the cathode plates are spaced apart along the length direction of the mounting frame.

[0020] Beneficial effects: The anode plates in the multiple processing boxes are electrically connected to the multiple cathode plates, so that each anode plate and cathode plate can electrolyze the waste liquid, and can quickly separate the metal ions and acid ions in the waste liquid, thereby improving the waste liquid treatment efficiency. If one of the anode plates or cathode plates fails, the other anode plates or cathode plates can operate normally, reducing the risk of downtime. The multiple processing boxes and cathode plates are spaced apart along the length direction of the mounting frame, making full use of the space so that more anode plates and cathode plates can be accommodated in a limited space.

[0021] In an optional embodiment, one cathode plate is correspondingly provided between two adjacent processing boxes.

[0022] Beneficial effect: Under normal circumstances, the side of the cathode plate facing the anode plate can normally separate metal ions, while the other side can separate relatively few metal ions. A cathode plate is correspondingly arranged between two adjacent processing boxes, so that both sides of the cathode plate face the anode plate, ensuring that both sides of the cathode plate can normally separate metal ions, so that both sides of the cathode plate are fully utilized.

[0023] In an optional embodiment, it also includes an anode connection bar and a cathode connection bar, wherein the anode connection bar and the cathode connection bar are suitable for connection to an external power source, and the anode connection bar and the cathode connection bar are respectively arranged on opposite sides of the top of the mounting frame, and the anode connection bar is correspondingly connected to the plurality of anode plates, and the cathode connection bar is correspondingly connected to the plurality of cathode plates.

[0024] Beneficial effects: The anode connection bar and the cathode connection bar are arranged on opposite sides of the top of the mounting frame, so that the anode connection bar and the cathode connection bar are away from the liquid surface of the waste liquid, avoiding short circuit and ensuring the stability and accuracy of power transmission. In addition, the anode connection bar and the cathode connection bar correspond to the corresponding anode plate and cathode plate one by one, so as to facilitate the electrical connection of multiple anode plates and cathode plates, making the electrical circuit structure clear and convenient for daily inspection, maintenance and troubleshooting.

[0025] In an optional embodiment, a plurality of slots are provided on the mounting frame corresponding to the processing box and the cathode plate, and the processing box and the cathode plate can be detachably mounted in the corresponding slots.

[0026] Beneficial effect: by opening a plurality of slots on the mounting frame and embedding the processing box and the cathode plate correspondingly in the slots, the processing box and the cathode plate can be quickly disassembled or installed, thus simplifying the maintenance work of the equipment.

[0027] In a second aspect, the utility model further provides an electroplating system, comprising:

[0028] a water tank, suitable for storing waste liquid;

[0029] The waste liquid treatment device, the mounting frame is arranged in the water tank.

[0030] Beneficial effects: This electroplating system sets the installation frame in the water tank so that the processing box and the cathode plate are in contact with the waste liquid. The metal ions (such as copper, tin, nickel, etc.) in the waste liquid are reduced on the cathode plate through electrolysis, and the acid radical ions in the waste liquid enter the cavity and concentrate, and are effectively separated from the water molecules in the waste liquid. The separated waste liquid can be reused because the main pollutants are removed, thereby reducing the waste of water resources, reducing the amount of waste liquid discharged, and effectively saving the cost of waste liquid treatment.

[0040] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0041] In the related art, in electroplating production, when the plate moves from tank A to tank B, the residual liquid medicine in tank A may flow into tank B along with the plate surface, causing the liquid medicine in tank B to be contaminated. In order to solve this problem, a set of water-blocking rollers is added between tank A and tank B to handle the residual liquid medicine on the plate surface. At the same time, two sets of water tanks are added between tank A and tank B to clean the residues on the plate surface that the rollers cannot handle. However, the washing liquid after cleaning contains a large amount of industrial liquid medicine. In order to ensure the cleanliness of the plate surface, it is necessary to continuously add new water to the water tank and discharge the waste liquid in the water tank, resulting in the need to consume a large amount of water resources in electroplating production and increase the cost of waste liquid treatment.

[0042] In order to solve the above technical problems, the following Figures 1 to 6 , describing an embodiment of the utility model.

[0043] According to an embodiment of the present utility model, on the one hand, as Figures 1 to 5As shown, a waste liquid treatment device is provided, including a mounting frame 1, a treatment box 2, an anode plate 4 and a cathode plate 5.

[0044] Specifically, combined Figure 2 and Figure 4 As shown, the processing box 2 is installed in the installation frame 1 and is suitable for being immersed in the waste liquid. The processing box 2 includes a box body 201 with a cavity (not shown in the figure) and an opening 204 opened at the top of the box body 201. At least one side of the box body 201 is provided with a hollow hole 202 and an ion membrane 3 is covered at the hollow hole 202. The ion membrane 3 is used to separate water molecules and acid radical ions in the waste liquid.

[0045] Specifically, combined Figure 1 and Figure 2 As shown, the anode plate 4 is disposed in the cavity from the opening 204 and is adapted to introduce acid ions into the cavity.

[0046] Specifically, combined Figure 1 and Figure 2 As shown, the cathode plate 5 is disposed in the waste liquid outside the processing box and is electrically connected to the anode plate 4.

[0047] This waste liquid treatment device, the positive plate 4 is arranged in the cavity of the treatment box 2 from the opening 204, so that the positive plate 4 contacts the waste liquid in the cavity, and the negative plate 5 is arranged in the waste liquid outside the treatment box 2, because the cavity is connected with the waste liquid through the ion membrane 3, under the conductive effect of the waste liquid, the negative plate 5 is electrically connected with the positive plate 4. Through the effect of electrolysis, the metal ions (such as copper, tin, nickel, etc.) in the waste liquid are reduced on the negative plate 5, and the acid radical ions in the waste liquid are reduced on the positive plate 4. Because the hollow hole 202 of the box body is covered with the ion membrane 3, the ion membrane 3 has selective permeability, allowing the acid radical ions to pass through and prevent water molecules from entering the cavity. Therefore, the acid radical ions generated in the electrolytic process can smoothly enter the cavity under the attraction of the positive plate 4 and be concentrated, and are effectively separated from the water molecules in the waste liquid. After the treatment is completed, it is only necessary to regularly collect the reduced metal ions from the negative plate 5, and take out the gathered acid radical ions from the cavity, so as to realize the extraction of metal and acid radical ions in the waste liquid. The separated waste liquid can be reused because the main pollutants are removed, thereby reducing the waste of water resources, reducing the amount of waste liquid discharged, and effectively saving the cost of waste liquid treatment.

[0049] Specifically, one or more hollow holes 202 can be opened on the processing box 2. The hollow holes 202 can be set on the side of one side of the processing box 2, or on adjacent sides or opposite sides. They can be selectively set according to needs. In the embodiment of the present application, the number and position of the hollow holes 202 are not specifically limited.

[0050] Specifically, the cavity of the processing box 2 can store liquid and place the anode plate 4, and any existing shape can be selected as needed. In the embodiment of the present application, the shape of the cavity is not specifically limited.

In the embodiment of the present application, the shapes of the anode plate 4 and the cathode plate 5 are not specifically limited.

[0052] In one embodiment, Figure 4 As shown, ion membranes 3 are provided on two opposite sides of the processing box 2.

[0053] Ion membranes 3 are arranged on two opposite sides of the treatment box 2. Due to the attraction of the acid ions in the waste liquid by the two sides of the anode plate 4, the acid ions on the two sides of the anode plate 4 pass through the ion membranes 3 on the corresponding sides and enter the cavity, which significantly increases the number of acid ions passing through the ion membranes 3 per unit time, thereby increasing the rate of transfer of acid ions from the waste liquid to the cavity and enhancing the aggregation efficiency. At the same time, it is helpful to form a more uniform acid ion concentration distribution in the cavity, avoid the phenomenon of excessively high or low local concentration caused by the ion membrane 3 on one side, and is conducive to maintaining the stable electrolysis and further improving the aggregation efficiency of the acid ions.

[0054] Specifically, the ion membrane 3 may be detachably covered on both sides of the processing box 2 to facilitate regular replacement of the ion membrane 3 . In the embodiment of the present application, no specific limitation is imposed on the detachable manner of the ion membrane 3 .

[0055] In one embodiment, Figure 4 As shown, a drainage cavity communicating with the cavity is provided on the side of the processing box 2, and a drainage port 203 is provided on the top of the drainage cavity.

[0056] After the waste liquid treatment is completed, since the drainage chamber is connected to the cavity, the waste liquid in the cavity will flow into the drainage chamber, and the waste liquid (aggregated acid ions) in the cavity can be discharged through the drainage port 203 at the top of the drainage chamber, so as to centrally collect the treated waste liquid and avoid the accumulation of treated waste liquid inside the equipment, affecting the normal operation of the equipment or causing secondary pollution.

[0057] Specifically, the drain outlet 203 can be set on a side close to the processing box 2, so that the liquid in the cavity can be poured out from the drain outlet 203 or extracted using an external extraction device. The drain outlet 203 can be set to be a square hole or a circular hole, etc. In the embodiment of the present application, the position and shape of the drain outlet 203 are not specifically limited.

[0058] In one embodiment, Figure 4 As shown, a connection portion 401 is provided on the anode plate 4 . When the anode plate 4 is installed in the cavity, the connection portion 401 of the anode plate 4 extends out of the opening 204 .

[0059] When the anode plate 4 is installed in the cavity, the connection portion 401 of the anode plate 4 extends out of the opening 204, so that the anode plate 4 is electrically connected to the external device through the connection portion 401, which simplifies the installation and removal process and saves operation time and labor costs. When the anode plate 4 needs to be inspected, cleaned or replaced, the connection portion 401 extends out of the opening 204 so that the operator can take out the anode plate 4 without going deep into the cavity.

[0060] Specifically, the connection portion 401 may be configured to be in a plate shape, a long rod shape, or other bent shapes, etc. In the embodiment of the present application, the shape of the connection portion 401 is not specifically limited.

[0061] Specifically, Figure 4 As shown, a connection hole 402 may be provided on the connection portion 401 , and an external connection line may be directly connected to the connection hole 402 on the connection portion 401 , so as to facilitate the connection between the connection portion 401 and the external connection line.

[0062] In one embodiment, in combination Figure 2 and Figure 4 As shown, the anode plate 4 and the cathode plate 5 are arranged in parallel.

[0063] The anode plate 4 and the cathode plate 5 are arranged parallel to each other, so that the distance between the anode plate 4 and the cathode plate 5 is constant, thereby ensuring that the electric field is relatively evenly distributed on the surface of the cathode plate 5, which is conducive to the metal ions forming a uniform metal deposition layer on both sides of the cathode plate 5. At the same time, the anode plate 4 and the cathode plate 5 are arranged parallel to each other, so that multiple anode plates 4 and cathode plates 5 can be arranged in a specified space.

[0064] In one embodiment, a plurality of the process boxes 2 and the cathode plates 5 are provided, and the plurality of process boxes 2 and the cathode plates 5 are spaced apart along the length direction of the mounting frame 1 .

[0065] The anode plates 4 in the multiple processing boxes 2 are electrically connected to the multiple cathode plates 5, so that each anode plate 4 and cathode plate 5 can electrolyze the waste liquid, and can quickly separate the metal ions and acid ions in the waste liquid, thereby improving the waste liquid treatment efficiency. If one of the anode plates 4 or the cathode plate 5 fails, the other anode plates 4 or the cathode plates 5 can operate normally, reducing the risk of downtime. The multiple processing boxes 2 and the cathode plates 5 are spaced apart along the length direction of the mounting frame 1, making full use of the space so that more anode plates 4 and cathode plates 5 can be accommodated in a limited space.

[0066] Specifically, the multiple processing boxes 2 and the cathode plate 5 can be arranged at uniform intervals or non-uniform intervals. In the embodiment of the present application, there is no specific limitation on the arrangement of the multiple processing boxes 2 and the cathode plate 5.

[0067] In one embodiment, Figure 2 As shown, a cathode plate 5 is disposed between two adjacent processing boxes 2 .

[0068] Under normal circumstances, the side of the cathode plate 5 facing the anode plate 4 can normally separate metal ions, while the other side can separate relatively few metal ions. A cathode plate 5 is correspondingly arranged between two adjacent processing boxes 2, so that both sides of the cathode plate 5 face the anode plate 4, ensuring that both sides of the cathode plate 5 can normally separate metal ions, so that both sides of the cathode plate 5 are fully utilized.

[0069] In one embodiment, Figure 2 As shown, it also includes an anode connection row 6 and a cathode connection row 7, which are suitable for connecting to an external power source. The anode connection row 6 and the cathode connection row 7 are respectively arranged on opposite sides of the top of the installation frame 1. The anode connection row 6 is correspondingly connected to multiple anode plates 4, and the cathode connection row 7 is correspondingly connected to multiple cathode plates 5.

[0070] The anode connection bar 6 and the cathode connection bar 7 are arranged on opposite sides of the top of the mounting frame 1, so that the anode connection bar 6 and the cathode connection bar 7 are away from the liquid surface of the waste liquid to avoid short circuit and ensure the stability and accuracy of power transmission. In addition, the anode connection bar 6 and the cathode connection bar 7 correspond to the corresponding anode plate 4 and the cathode plate 5 one by one, so as to facilitate the electrical connection of multiple anode plates 4 and cathode plates 5, so that the electrical circuit structure is clear and convenient for daily inspection, maintenance and troubleshooting.

[0072] In one embodiment, in combination Figure 2 and Figure 3 As shown, a plurality of slots 101 are provided on the mounting frame 1 corresponding to the processing boxes 2 and the cathode plates 5 , and both the processing boxes 2 and the cathode plates 5 can be detachably mounted in the corresponding slots 101 .

[0073] By opening a plurality of slots 101 on the mounting frame 1 and embedding the processing box 2 and the cathode plate 5 in the slots 101 correspondingly, the processing box 2 and the cathode plate 5 can be quickly disassembled or installed, thus simplifying the maintenance of the equipment.

[0074] The working principle of the waste liquid treatment device in this embodiment is described as follows:

[0075] First, a certain amount of liquid is injected into the cavity, and the anode plate 4 is set in the cavity of the processing box 2 so that the anode plate 4 contacts the liquid in the cavity, and the cathode plate 5 is set in the waste liquid. Under the conductive effect of the waste liquid and the liquid, the cathode plate 5 is electrically connected to the anode plate 4.

[0076] The metal ions (such as copper, tin, nickel, etc.) in the waste liquid are reduced on the cathode plate 5 by electrolysis, and the acid radical ions in the waste liquid are reduced on the anode plate 4. Since the hollow hole 202 is covered with an ion membrane 3, the ion membrane 3 has selective permeability, allowing the acid radical ions to pass through and preventing water molecules from entering the cavity. Therefore, the acid radical ions generated during the electrolysis process can smoothly enter the cavity and concentrate, and are effectively separated from the water molecules in the waste liquid.

[0077] The reduced metal ions collected on the cathode plate 5 are scraped off regularly, and the liquid containing acid ions in the cavity is pumped out through the drain port 203, so that the metal ions and acid ions in the waste liquid can be extracted, so that the waste liquid can be reused, effectively saving the cost of waste liquid treatment.

[0081] In this electroplating system, the mounting frame 1 is arranged in the water tank 8, so that the processing box 2 and the cathode plate 5 are both in contact with the waste liquid. The metal ions (such as copper, tin, nickel, etc.) in the waste liquid are reduced on the cathode plate 5 by the action of electrolysis, and the acid radical ions in the waste liquid enter the cavity and concentrate, and are effectively separated from the water molecules in the waste liquid. The separated waste liquid can be reused because the main pollutants are removed, thereby reducing the waste of water resources, reducing the amount of waste liquid discharged, and effectively saving the cost of waste liquid treatment.
