The sedimentation tank is opened through the sedimentation filter screen at the end near the sedimentation filter screen. The sedimentation filter screen is fixed in the middle position between the sedimentation tank and the storage cavity. The electroplating solution is filtered twice through the sedimentation filter screen at the bottom. The solid impurities in the electroplating solution are filtered out through the two filtration operations, completing the pretreatment operation of electroplating solution recovery. At the same time, the filtered metal solid impurities can be recovered, improving the recovery and treatment efficiency of the electroplating solution.

[0004] The existing electroplating solution recovery equipment has a long maintenance time, which affects production continuity and overall efficiency. The replacement process of filter media is also cumbersome, which increases the workload of maintenance personnel and operating costs, thus restricting the effectiveness and widespread application of the equipment.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1 - Figure 6 The present invention provides the following technical solution: an electroplating solution recovery device with a filtration mechanism, comprising a recovery tank 1, a filter tank 2 fixedly connected to the top of the recovery tank 1 by a flange, and a filtration structure installed inside the filter tank 2.

[0026] like Figure 3As shown, a mounting ring 3 is fixedly connected to the top of the filter tank 2. The mounting ring 3 has L-shaped positioning grooves 4 inside. A cover plate 5 is installed on the top of the mounting ring 3. A ring-shaped positioning block 7 is fixedly connected to the bottom of the cover plate 5. The positioning block 7 is engaged with the inside of the positioning block 7 to form a quick-release structure. The filter structure includes a connecting sleeve 8 fixedly connected to the bottom of the cover plate 5. A disassembly sleeve 12 is threadedly connected to the bottom of the connecting sleeve 8.

[0027] like Figure 4 and Figure 5 As shown, a handle 6 is fixedly connected to the top of the cover plate 5. The connecting sleeve 8 and the disassembly sleeve 12 are both inserted into the filter tank 2. Both the connecting sleeve 8 and the disassembly sleeve 12 are hollow structures. A first sealing ring 9 is fixedly connected to the outer side of the upper end of the connecting sleeve 8, and a second sealing ring 10 is fixedly connected to the outer side of the lower end of the connecting sleeve 8. The second sealing ring 10 is located outside the connection between the disassembly sleeve 12 and the connecting sleeve 8. A clamping ring 11 is fixedly connected to the inner side of the lower end of the connecting sleeve 8. A hollow sliding sleeve 13 is inserted inside the disassembly sleeve 12. Filter material 14 is fixedly connected inside the sliding sleeve 13. The tops of the sliding sleeve 13 and the filter material 14 are flush with the top of the disassembly sleeve 12, and the tops of the disassembly sleeve 12, the sliding sleeve 13, and the filter material 14 are all in contact with the bottom of the clamping ring 11.

[0028] like Figure 6 As shown, a partition plate 15 is fixedly connected in the middle of the filter tank 2. The partition plate 15 divides the filter tank 2 into a sewage chamber 16 and a clean water chamber 17. The clean water chamber 17 is connected to the recovery storage tank 1. The connecting sleeve 8 is located inside the sewage chamber 16, and the disassembly sleeve 12 is located inside the clean water chamber 17.

[0029] During the filtration process, wastewater enters the connecting sleeve 8 from the sewage chamber 16. A clamping ring 11 is installed inside the connecting sleeve 8, which is fixed to the inner side of the lower end of the connecting sleeve 8. A sliding sleeve 13 is inserted inside the disassembly sleeve 12. The sliding sleeve 13 also has a hollow structure, and filter media 14 is fixedly connected inside to intercept solid particles and impurities in the wastewater. In the working state, the tops of the sliding sleeve 13 and the filter media 14 are flush with the top of the disassembly sleeve 12 and together fit with the bottom of the clamping ring 11 to form a tight fit. This ensures that after the wastewater flows through the connecting sleeve 8, it can only contact the filter media 14 through the hollow structure of the disassembly sleeve 12 and the sliding sleeve 13, thereby achieving filtration. The wastewater permeates the filter media 14 under pressure or gravity, and the impurities are intercepted by the filter media. The filtered clean liquid then enters the clean water chamber 17.

[0030] The filtered clean liquid collects in the clean water chamber 17, which is directly connected to the recycling tank 1. After filtration, the liquid flows naturally into the recycling tank 1. In the recycling tank 1, the filtered electroplating solution can be stored or reused, thus completing the recycling process.

[0031] The bottom of the cover plate 5 is fixedly connected with a ring of equally spaced positioning blocks 7. During installation, the positioning blocks 7 engage with the positioning groove 4 to form a quick disassembly and assembly structure. By rotating the handle 6, the cover plate 5 can be quickly disassembled and assembled at the top of the mounting ring 3. When the filter media 14 becomes saturated or clogged due to use, the operator can remove the cover plate 5 through the handle 6, thereby taking the connecting sleeve 8 and the disassembly sleeve 12 out of the filter tank 2 together. Then, the disassembly sleeve 12 can be unscrewed from the bottom of the connecting sleeve 8, and the sliding sleeve 13 can slide out from inside the disassembly sleeve 12, making it convenient to replace the new filter media 14. This quick disassembly design greatly improves maintenance efficiency and eliminates the need for professional tools or long-term downtime.

[0032] Example 2: Based on Example 1, please refer to... Figure 3 The following structure is also disclosed: the first sealing ring 9 installed on the outer side of the upper end of the connecting sleeve 8 forms a sealing structure with the edge of the top opening of the mounting ring 3; the second sealing ring 10 installed on the outer side of the lower end of the connecting sleeve 8 forms a sealing structure with the edge of the middle opening of the isolation plate 15; the filter tank 2 is fixedly connected to the outside of the filter tank 2 with vertically distributed water inlet pipes 18, and the water inlet pipes 18 and the sewage chamber 16 are connected.

[0033] The first sealing ring 9 installed on the outer side of the upper end of the connecting sleeve 8 forms a sealing structure with the edge of the top opening of the mounting ring 3. The top of the mounting ring 3 has an opening for the insertion of the connecting sleeve 8. The first sealing ring 9 is located at the edge of this opening. After the cover plate 5 is installed, the first sealing ring 9 is deformed by pressure and fits tightly against the edge of the mounting ring 3 to prevent the liquid in the sewage chamber 16 from leaking from the top of the filter tank 2. At the same time, the second sealing ring 10 installed on the outer side of the lower end of the connecting sleeve 8 forms another sealing structure with the edge of the middle opening of the isolation plate 15. The middle opening of the isolation plate 15 is used for the passage between the connecting sleeve 8 and the disassembly sleeve 12. The second sealing ring 10 is located on the outer side of this connection to ensure that when the disassembly sleeve 12 is located in the clean water chamber 17, the liquid can only flow through the filter material 14 and will not cross-leak between the sewage chamber 16 and the clean water chamber 17. This maintains the isolation between the sewage chamber 16 and the clean water chamber 17 and prevents unfiltered liquid from directly entering the recovery area, thereby improving the filtration accuracy.

[0034] Electroplating wastewater can be directly transported from an external source to the wastewater chamber 16 through the inlet pipe 18. After entering the wastewater chamber 16, the wastewater flows to the connecting sleeve 8 under the pressure gradient. The first sealing ring 9 at the upper end of the connecting sleeve 8 ensures that there is no leakage here, so the liquid can only flow downwards. The disassembly sleeve 12 is threaded to the bottom of the connecting sleeve 8. The liquid passes through the hollow structure of the connecting sleeve 8 and the disassembly sleeve 12, contacts and permeates the filter material 14. The filter material 14 traps solid impurities, while the filtered clean liquid passes through the disassembly sleeve 12 and enters the clean water chamber 17. The second sealing ring 10 prevents the liquid from flowing backwards from the opening of the isolation plate 15, ensuring that the clean water chamber 17 only receives the filtered liquid. Finally, the clean liquid gathers in the clean water chamber 17 and flows into the recovery storage tank 1 for subsequent use.
