Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and specifically to a multi-stage capacitor deionization device for electroplating wastewater. Background Art

[0002] Electroplating wastewater refers to the wastewater or waste liquid discharged from electroplating production. A large amount of wastewater will be generated during the electroplating production process, which contains various toxic and harmful substances such as chromium, cyanide, cadmium, nickel, zinc, copper, phosphate, acid and alkali.

[0003] When discharging electroplating wastewater, it is usually necessary to filter the electroplating wastewater to meet the discharge standards and prevent the direct discharge of electroplating wastewater from polluting the environment. In addition, the metal ions in the electroplating wastewater must be separated to facilitate the recovery of some metal ions during sewage treatment.

[0004] In the treatment process of electroplating wastewater, refer to the patent document CN212174542U. The device proposed in the patent document is interconnected by conductive sheets evenly distributed on the anode conductive plug-in plate and the cathode conductive plug-in plate and the electrode plate. The integrated design facilitates the positive-reverse cycle operation of the power supply. The electrode plate is fixed in the slot of the U-shaped slot through the card slot design, which is convenient for the installation and removal of the electrode plate. However, in the actual application of electroplating wastewater treatment, although the device can electrolyze the electroplating wastewater and can quickly install and remove the electrode plate, after long-term use of the device components, a large amount of dirt will adhere to the surface of the components. If it is not cleaned, it will affect the subsequent treatment effect of the electroplating wastewater. Long-term use will lead to a decrease in the use effect. Summary of the invention

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1-2 As shown, this embodiment proposes a multi-stage capacitive deionization device for electroplating wastewater, including a casing 1, a quick disassembly mechanism 2 is provided inside the casing 1, the quick disassembly mechanism 2 includes five groups of slide bars 201 slidably connected to the reserved grooves on the inner wall of the casing 1, and a side of each group of slide bars 201 close to each other is respectively fixedly connected to a cation filter layer 202, an anion filter layer 203, a nickel ion adsorption layer 204, a medium filter layer 205 and an activated carbon filter layer 206, and the upper surfaces of the cation filter layer 202, the anion filter layer 203, the nickel ion adsorption layer 204, the medium filter layer 205 and the activated carbon filter layer 206 are all fixedly connected to a fixed plate 207.

[0026] In this embodiment, by setting the sliding bar 201, it can slide stably with the sliding groove opened on the inner wall of the box body 1, so as to better stably install the cation filter layer 202, the anion filter layer 203, the nickel ion adsorption layer 204, the medium filter layer 205 and the activated carbon filter layer 206, so that multiple layer plates can be quickly installed and disassembled, avoiding multiple layer plates being fixed inside the device for a long time and causing dirt adhering between the layer plates to affect the subsequent use effect.

[0027] A water pump 3 is installed on the outer surface of the box body 1, and the water inlet end and the water outlet end of the water pump 3 are fixedly connected with the water inlet pipe 4 and the three-way 5 respectively, and the end of the three-way 5 away from the water pump 3 passes through the outer surface of the box body 1 and extends to the interior of the box body 1. The right side of the box body 1 is fixedly connected with the outlet pipe 6. By setting the water pump 3, the electroplating wastewater can be better filled into the interior of the device, and the electroplating wastewater is discharged from the outlet pipe 6 after the treatment is completed, thereby realizing the continuous treatment efficiency of the electroplating wastewater and greatly improving the work efficiency.

[0028] Support legs 7 are fixedly connected to the four corners of the bottom surface of the box body 1, and a foot pad 8 is fixedly connected to the lower end of each support leg 7. By setting the support legs 7, the stability of the entire device can be better improved, and the friction between the device and the ground can be greatly increased through the foot pad 8, thereby reducing the shaking of the device when it is used.

[0029] Two display instruments 9 are installed on the front of the box 1, and a controller 10 is installed on the front of the box 1. By setting the display instruments 9 and the controller 10, the working operation and treatment process of the electroplating wastewater can be better controlled and observed, thereby improving the practicality of the device.

[0030] The upper surface of the box body 1 is hinged with equidistantly arranged cover plates 11, and the upper surface of the cover plate 11 is fixedly connected with a clamping plate 12, and one end of each clamping plate 12 away from the cover plate 11 extends to the outside of the cover plate 11. By setting the cover plate 11, the risk of wastewater splashing to the outside and causing injury to the staff during treatment can be better prevented, and dirt can also be prevented from falling into the inside of the device and affecting the work efficiency.

[0031] Example 2

[0032] like Figure 3-4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes a fixing plate 207, and the upper surface of each fixing plate 207 is fixedly connected with two groups of symmetrical fixing frames 208, and the side surface of each group of fixing frames 208 close to each other is fixedly connected with a fixing rod 209, and the outer surface of the fixing rod 209 is rotatably connected with an L-shaped clip strip 2010, and the front and back sides of the box body 1 are fixedly connected with equidistantly arranged clip blocks 2011.

By providing the handle 13, it is easier for the staff to manually pull out the shelf for cleaning and disassembly and maintenance.

[0036] Five groups of conductive sheets 15 arranged at equal distances are provided inside the box 1, and mounting blocks 14 are installed at both ends of the conductive sheets 15. The side of each mounting block 14 away from the conductive sheet 15 is installed on the inner wall of the box 1. By arranging the conductive sheets 15, the electroplating wastewater can be better electrolyzed through multi-stage capacitors, and then the nickel ions can be adsorbed through subsequent adsorption components. In addition, different metal ions can be adsorbed by replacing the nickel ion adsorption layer 204 and filling it with specific chemical liquids, which greatly improves the application range of the device.

[0037] The specific implementation process of the utility model is as follows: by starting the water pump 3, the water pump 3 draws the electroplating wastewater into the device through the water inlet pipe 4, and pours it into the interior of the box 1 through the three-way 5, and fills the box 1 with a specific chemical solution. The electroplating wastewater passes through the cation filter layer 202, the anion filter layer 203, the nickel ion adsorption layer 204, the medium filter layer 205 and the activated carbon filter layer 206. The metal ions in the electroplating wastewater can be treated, and in the treatment process, the controller 10 controls the start of the conductive sheet 15, so that the electroplating wastewater is electrolyzed by multiple conductive sheets 15, and the electroplating wastewater is fully reacted with the added special chemical solution, so that the nickel ions in the electroplating wastewater are separated, and then adsorbed by the nickel ion adsorption layer 204. After the adsorption is completed, the nickel ion adsorption layer 204 can be taken out by pressing the L-shaped card strips 2010 on both sides and pulling the handle 13. The other layer plates can also be taken out in the same way, thereby realizing the treatment of nickel ions.
