Description

Technical Field

[0001] This utility model relates to the technical field of waste liquid treatment devices, and in particular to a treatment device for micro-etching waste liquid and copper sulfate waste liquid. Background Technology

[0002] In the treatment of micro-etching waste liquid and copper sulfate waste liquid, electrolysis is one of the commonly used treatment methods. It achieves the reduction and deposition of metal ions or the decomposition of harmful components in the waste liquid through the electrolytic reaction of titanium anode and titanium cathode. However, the existing technology still has significant defects in practical applications: On the one hand, the mixing uniformity of dilute sulfuric acid and waste liquid during electrolysis is insufficient, and the acid concentration is easily uneven in local areas, resulting in insufficient reaction on the surface of titanium cathode. This not only reduces the electrolysis efficiency, but may also affect the cathode performance due to local over-corrosion. On the other hand, titanium cathode is prone to scale formation during electrolysis due to metal ion reduction deposition (such as copper ion precipitation) or oxidation reaction. Traditional cleaning methods mostly rely on mechanical scraping at fixed positions or manual disassembly and cleaning, which is difficult to adapt to cathode surfaces of different sizes or in motion. Incomplete cleaning will lead to a continuous decline in cathode activity, shorten service life, and increase downtime and maintenance time and costs. Summary of the Invention

[0003] To overcome the technical defects of the existing technology, this utility model provides a treatment device for micro-etching waste liquid and copper sulfate waste liquid, which can promote full contact between the acid liquid and the surface of the titanium cathode, avoid the effect of uneven local concentration on the reaction effect, and effectively remove scale or deposits on the surface of the titanium cathode.

[0004] The technical solution adopted by this utility model is as follows: it includes an installation box, in which a titanium anode and a titanium cathode are installed. The upper surface of the installation box is provided with a placement box for placing dilute sulfuric acid. A conductive rod is provided at the upper end of the titanium cathode. A motor for driving the titanium cathode is provided at the bottom of the installation box. A mixing component is provided on the conductive rod.

The toothed disc is fixedly installed inside the mounting box, the toothed disc is rotatably connected to the conductive rod, and the rotating plate is connected to the conductive rod. A rotating shaft is rotatably installed on the rotating plate, and a stirring blade is connected to the rotating shaft.

[0006] Preferably, in order to facilitate the rotation of the rotating shaft, a gear is fixedly installed on the rotating shaft, and the gear meshes with the gear plate.

[0007] Preferably, in order to flexibly adjust the position of the scraper, the adjustable cleaning assembly includes a telescopic cylinder, which is mounted on the mounting box. A mounting plate is mounted on the output end of the telescopic cylinder, an electric telescopic rod is mounted on the mounting plate, a spray plate is mounted on the output end of the electric telescopic rod, and a scraper is provided on the spray plate.

[0008] Preferably, in order to spray dilute sulfuric acid onto the titanium cathode, the spray plate has a hollow internal structure, and the spray plate and the area below the scraper are provided with spray holes arranged in an array.

[0009] Preferably, in order to facilitate the transfer of dilute sulfuric acid into the spray plate, the spray plate is provided with a connecting hose, the other end of which is fixedly connected to the output end of the pump body.

[0010] Preferably, in order to add raw materials into the installation box, the installation box is provided with a discharge port on one side and a feed port on the installation box.

[0011] Preferably, to prevent the bottom of the mounting box from directly contacting the ground, the lower surface of the mounting box is provided with support feet.

[0012] The beneficial effects of this utility model are:

[0013] 1. Through the mixing component, when the conductive rod rotates with the titanium cathode, the meshing transmission of the gear and the toothed disc can drive the rotating shaft to rotate, which in turn drives the stirring blade to stir the dilute sulfuric acid, promotes full contact between the acid and the surface of the titanium cathode, enhances the uniformity and efficiency of the electrolysis reaction, and avoids the effect of local uneven concentration on the reaction.

[0014] 2. Through the coordination of adjustable cleaning components and pump body, telescopic cylinder and electric telescopic rod, the relative position of the spray plate and titanium cathode can be flexibly adjusted to adapt to cathode surfaces of different sizes or positions. The pump body draws dilute sulfuric acid from the placement tank to the spray plate, which can simultaneously realize the dual operation of "acid spraying" and "scraper cleaning", effectively removing scale or deposits on the surface of titanium cathode, maintaining cathode activity and extending service life.

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] like Figures 1-5 As shown, this embodiment provides a treatment device for micro-etching waste liquid and copper sulfate waste liquid, including an installation box 1. A titanium anode 2 and a titanium cathode 3 are installed inside the installation box 1. A placement box 5 containing dilute sulfuric acid is provided on the upper surface of the installation box 1. A conductive rod 4 is provided at the upper end of the titanium cathode 3. A motor 12 for driving the titanium cathode 3 is provided at the bottom of the installation box 1. A mixing component 6 is provided on the conductive rod 4 to promote full contact between the acid and the surface of the titanium cathode 3, enhance the uniformity and efficiency of the electrolysis reaction, and avoid local uneven concentration affecting the reaction effect. An adjustable cleaning component 7 for cleaning the titanium cathode 3 is provided on the installation box 1 to effectively remove scale or deposits on the surface of the titanium cathode 3, maintain cathode activity, and extend service life. A pump body 8 is provided on the surface of the installation box 1. The output end of the pump body 8 is connected to the adjustable cleaning component 7, and the inlet end of the pump body 8 is connected to the placement box 5.

[0023] As a technical optimization solution of this utility model, specifically as follows: Figure 4As shown, the mixing component 6 includes a geared disc 601 and a rotating plate 602. The geared disc 601 is fixedly installed inside the mounting box 1 and is rotatably connected to the conductive rod 4. The rotating plate 602 is also connected to the conductive rod 4. A rotating shaft 603 is rotatably mounted on the rotating plate 602, and a stirring blade 604 is connected to the rotating shaft 603. A gear 605 is fixedly mounted on the rotating shaft 603 and meshes with the geared disc 601. The motor 12 drives the titanium cathode 3 to rotate, and the conductive rod 4 at the upper end of the titanium cathode 3 rotates accordingly. During the rotation of the conductive rod 4... In the process, the mixing component 6 on it starts to work. Since the toothed disc 601 is fixedly installed inside the mounting box 1, the rotating plate 602 is connected to the conductive rod 4, and the rotating shaft 603 on the rotating plate 602 meshes with the toothed disc 601 through the gear 605, when the conductive rod 4 rotates, the rotating plate 602 rotates accordingly, and the gear 605 on the rotating shaft 603 rolls on the toothed disc 601, thereby driving the rotating shaft 603 and the stirring blade 604 to rotate, stirring the waste liquid in the mounting box 1, so that the copper ions in the waste liquid are evenly distributed and the electrolysis efficiency is improved.

[0024] As a technical optimization solution of this utility model, specifically as follows: Figure 5 As shown, the adjustable cleaning assembly 7 includes a telescopic cylinder 701, which is mounted on the mounting box 1. A mounting plate 702 is mounted on the output end of the telescopic cylinder 701. An electric telescopic rod 703 is mounted on the mounting plate 702. A spray plate 704 is mounted on the output end of the electric telescopic rod 703. A scraper 705 is provided on the spray plate 704. The spray plate 704 has a hollow internal structure. An array of spray holes 706 are provided on the spray plate 704 and below the scraper 705. A connecting hose 707 is provided on the spray plate 704. The other end of the connecting hose 707 is fixedly connected to the output end of the pump body 8. Activating the telescopic cylinder 701... 1. Move the mounting plate 702 to bring the spray plate 704 closer to the titanium cathode 3. Extend the electric telescopic rod 703 to further adjust the position of the spray plate 704 so that the scraper 705 fits against the surface of the titanium cathode 3. Start the pump body 8 to deliver the dilute sulfuric acid in the storage box 5 to the inside of the spray plate 704 through the connecting hose 707. The dilute sulfuric acid is sprayed out in an array from the spray hole 706 to rinse the surface of the titanium cathode 3. After rinsing, repeat the above operation to clean the scraper 705 and the surface of the titanium cathode 3. The mounting box 1 has a discharge port 9 on one side and a feed port 10 on the top. The mounting box 1 has support feet 11 on the lower surface.

[0025] In use, the micro-etching waste liquid and copper sulfate waste liquid are introduced into the installation box 1 through the feed port 10, submerging the titanium anode 2 and titanium cathode 3. Then, the conductive rod 4 is connected to an external power source to provide current for the electrolysis process. Simultaneously, the motor 12 is started, driving the titanium cathode 3 to rotate. The conductive rod 4 at the upper end of the titanium cathode 3 rotates accordingly. During the rotation of the conductive rod 4, the mixing component 6 on it begins to operate. Since the geared disc 601 is fixedly installed inside the installation box 1, and the rotating plate 602 is connected to the conductive rod 4, the rotating shaft 603 on the rotating plate 602 meshes with the geared disc 601 through a gear 605. Therefore, when the conductive rod 4 rotates, the rotating plate 602 rotates accordingly, and the gear 605 on the rotating shaft 603 rolls on the geared disc 601, thereby driving the rotating shaft 603 and the stirring blade 604 to rotate, stirring the waste liquid in the installation box 1, ensuring uniform distribution of copper ions in the waste liquid, and improving electrolysis efficiency. During electrolysis, copper ions gain electrons on the surface of the titanium cathode 3 and are reduced to elemental copper, which is then deposited on the titanium cathode 3. To ensure the electrolysis effect of the titanium cathode 3, it needs to be cleaned regularly. At this time, the adjustable cleaning component 7 is activated, the telescopic cylinder 701 is activated, and the mounting plate 702 is moved to bring the spray plate 704 closer to the titanium cathode 3. The electric telescopic rod 703 extends to further adjust the position of the spray plate 704. The pump body 8 is activated, and the dilute sulfuric acid in the storage box 5 is transported to the inside of the spray plate 704 through the connecting hose 707. The dilute sulfuric acid is sprayed out in an array from the spray hole 706 to rinse the surface of the titanium cathode 3. After rinsing, the above operation is repeated to clean the surface of the titanium cathode 3 with the scraper 705. After cleaning, the telescopic cylinder 701 and the electric telescopic rod 703 are reset, and the spray plate 704 is moved away from the titanium cathode 3. The treated waste liquid can be discharged through the discharge port 9 on one side of the mounting box 1 for subsequent treatment or recycling.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention.
