Description
Technical Field
[0001] This utility model relates to the field of electroplating wastewater treatment, and in particular to a filter box for electroplating wastewater treatment. Background Technology
[0002] Electroplating wastewater refers to wastewater containing pollutants such as heavy metal ions, acids, alkalis, and organic matter generated during the electroplating production process. If not properly treated, it can cause serious harm to the environment and human health. The core of electroplating wastewater treatment is to remove or transform pollutants so that the wastewater meets discharge standards or reuse requirements. In electroplating wastewater treatment, the filter box is an indispensable key link. Its core function is to remove pollutants from the wastewater through physical interception, adsorption, and other mechanisms, ensuring the stability of subsequent treatment processes and that the final effluent meets the standards.
[0003] The existing technology has the following drawbacks: most electroplating wastewater filter boxes adopt a fixed capacity design, which makes it difficult to adjust according to changes in the actual wastewater treatment volume. When the treatment demand increases, it is necessary to replace the filter box with a larger one, which is not only cumbersome to operate but also costly. On the other hand, when the treatment volume is small, large-capacity filter boxes will result in resource waste. Therefore, a filter box for electroplating wastewater treatment is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a filter box for electroplating wastewater treatment, aiming to improve the problem that the fixed capacity of the filter box in the prior art cannot handle the amount of wastewater in different situations.

[0032] 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.
[0033] Reference Figure 1 , Figures 3-4 This utility model provides an embodiment of a filter box for electroplating wastewater treatment, including a main filter box 1. A long plate 2 is fixedly connected to the top of the main filter box 1. A sealing groove is opened on the top of the long plate 2. A storage tank 8 is set at the top of the main filter box 1. A square plate 3 is fixedly connected to the bottom of the storage tank 8. A waterproof rubber sealing ring is fixedly connected to the bottom of the square plate 3. When the sealing ring is engaged in the sealing groove, it can ensure the sealing performance after the main filter box 1 and the storage tank 8 come into contact, ensuring that no leakage occurs during the wastewater treatment process. A block 6 is fixedly connected to the bottom of the square plate 3. The block 6 has a slot, which can satisfy the overlap of the wedge 5 with the slot of the block 6, thereby limiting the entire block 6 and the square plate 3. A fixing mechanism is provided on the inner wall of the long plate 2. A pull-out assembly is provided on the inner wall of the main filter box 1. A drain outlet 14 is fixedly connected to the right side of the main filter box 1.
[0034] The fixing mechanism includes a U-shaped plate 4, which is slidably connected to the inner wall of the long plate 2. The inner wall of the long plate 2 has a slot to allow the U-shaped plate 4 and the wedge block 5 to slide on the inner wall of the long plate 2. The wedge block 5 is fixedly connected to the left side of the U-shaped plate 4. The U-shaped plate 4 is elastically connected to the long plate 2 through a return spring 7.
[0035] Reference Figure 1 , Figure 5 and Figure 6 The pull-out assembly includes a pull-out box 9, which is inserted into the inner wall of the main filter box 1. A rubber strip 10 is fixedly connected to the surface of the pull-out box 9. The rubber strip 10 is made of highly waterproof rubber. When the pull-out box 9 is placed in the main filter box 1 to collect sediment, the rubber strip 10 can ensure that sewage will not leak. A cylinder 12 is elastically connected to the inner wall of the main filter box 1 through a torsion spring 13. A rotating plate 11 is fixedly connected to the end of the cylinder 12. The long plate 2 and the square plate 3 are attached to each other. The cylinder 12 is rotatably connected to the inner wall of the main filter box 1. The outer wall of the cylinder 12 is fixedly connected to one end of the torsion spring 13. The other end of the torsion spring 13 is fixedly connected to the inner wall of the main filter box 1. When the rotating cylinder 12 drives the rotating plate 11 to rotate, it will squeeze the torsion spring 13. After releasing, the torsion spring 13 will use its elasticity to bring the cylinder 12 and the rotating plate 11 back to their original position. The outer wall of the rotating plate 11 contacts the outer wall of the pull-out box 9.
[0036] Reference Figures 2-4 The cube 6 is inserted into the inner wall of the long plate 2. The long plate 2 has slots around its perimeter to allow the cube 6 to be inserted into the top slot of the long plate 2. The inner side wall of the U-shaped plate 4 is fixedly connected to one end of the return spring 7, and the other end of the return spring 7 is fixedly connected to the inner wall of the long plate 2. When the U-shaped plate 4 is pulled backward, the return spring 7 is compressed. When released, the return spring 7 will bring the U-shaped plate 4 back to its original position. The wedge 5 is slidably connected to the inner wall of the long plate 2 and inserted into the inner wall of the cube 6. There are four cubes 6 and four wedges 5, which are respectively set around the perimeter of the long plate 2 and the square plate 3.
[0037] Working principle: When the operator uses the filter box to filter sewage, they pull the U-shaped plate 4 backward, moving the wedge block 5 backward together. The return spring 7 deforms, and the block 6 on the square plate 3 is inserted into the long plate 2. Since the square plate 3 and the storage tank 8 are fixedly connected, the storage tank 8 will come into contact with the main filter box 1. After releasing the U-shaped plate 4, the U-shaped plate 4 will return to its original position under the elastic action of the return spring 7, so that the wedge block 5 is engaged in the slot on the block 6. This completes the connection between the main filter box 1 and the storage tank 8. When the storage tank 8 is no longer needed, the U-shaped plate 4 is pulled backward again to disengage the wedge block 5 from the slot on the block 6. The block 6 fixed at the bottom of the square plate 3 is then removed to complete the disassembly.
[0038] After the staff pours the electroplating wastewater into the filter box, they add flocculant, which reacts with the wastewater to produce sediment. Under the action of gravity, the sediment falls into the pull-out box 9 on the inner wall of the main filter box 1. After the wastewater filtration is completed and discharged from the drain outlet 14, the rotating plate 11 is turned clockwise to move the cylinder 12, releasing the limiting position of the rotating plate 11 on the pull-out box 9. The pull-out box 9 can then be pulled out to clean the accumulated sediment. After cleaning, the pull-out box 9 is inserted back into the inner wall of the main filter box 1, and the rotating plate 11 is released. At this time, the rotating plate 11 will drive the cylinder 12 to reset under the elastic force of the torsion spring 13, thus limiting the pull-out box 9.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
