Technical Field

[0001] This application relates to the field of metal recycling, and in particular to an electrolytic recycling device for nickel waste liquid. Background Technology

[0002] Nickel is an important strategic resource with wide applications in many industrial sectors. However, the production and use of nickel generate a large amount of nickel-containing waste liquid. If this waste liquid is not effectively treated, it will not only waste resources but also cause serious environmental pollution. Traditional nickel recycling methods suffer from problems such as low recycling efficiency, high energy consumption, and complex operation. Furthermore, the nickel metal deposited on the cathode plate often needs to be scraped off manually, which increases labor intensity and costs. Utility Model Content

The movement of the upward moving rectangular frame drives the left moving rectangular frame to move, thereby realizing the adjustment of the cathode plate height. The output end of the first motor drives the threaded rod to rotate. The rotation of the threaded rod drives the guide block, the left moving rectangular frame and another guide block on it to move along the horizontal direction of the guide rod away from the first motor, which makes it easier for the operator to remove the cathode plate from the electrolytic cell.

[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0021] This application discloses a nickel waste liquid electrolytic recovery device, referring to... Figures 1-3 The system includes an electrolytic cell 1, which uses an external power source to cause ions in the electrolyte solution or molten electrolyte to move in a specific direction and undergo oxidation-reduction reactions at the cathode and anode, thereby converting electrical energy into chemical energy. A fixed rectangular frame 3 is fixedly fitted onto the top of the electrolytic cell 1. An upward-moving rectangular frame 6 is movably mounted on the top surface of the fixed rectangular frame 3. A left-moving rectangular frame 7 is movably mounted on the top surface of the upward-moving rectangular frame 6. Four inverted concave frames 8 are horizontally and equidistantly fixed on the top surface of the left-moving rectangular frame 7. Four cathode plates 9 are respectively fixed to the inner top surface of each inverted concave frame 8 by screws. An adjustment mechanism is installed on the inverted concave frames 8 to adjust the height and horizontal position of the cathode plates 9. Two scrapers 14 are symmetrically installed on the cathode plates. On both sides of 9, two vertical rods 15 vertically and movably pass through both ends of the scraper 14. A second limiting plate 16 is fixedly installed on the bottom surface of the vertical rod 15. The top surface of the vertical rod 15 is connected to the inverted concave frame 8. It also includes a titanium-based coated anode plate installed at the inner bottom of the electrolytic cell 1. It also includes eight long connecting rods 19, which are movably connected to each scraper 14 through shafts. Short connecting rods 20 are movably connected to the other end of the long connecting rods 19 through shafts. An L-shaped frame 17 is installed on the top surface of one of the inverted concave frames 8. A dual-axis motor 18, model 57MM25A54, is installed on the L-shaped frame 17. Two rotating rods 21 are installed at the output ends of the dual-axis motor 18. The short connecting rods 20 are fixedly sleeved on the rotating rods 21.

[0022] In this embodiment, the output ends of the dual-axis motor 18 drive the rotating rod 21 to rotate. The rotation of the rotating rod 21 drives the short connecting rod 20 to move. The movement of the short connecting rod 20 drives the long connecting rod 19 and the scraper 14 to move up and down along the vertical direction of the vertical rod 15. The scraper 14 scrapes off the nickel metal deposited on the cathode plate 9, which facilitates the subsequent purification process.

[0023] Reference Figures 1-2The adjustment mechanism includes two hydraulic cylinders 5, model HOB40X450, which are respectively set at two opposite corners of the bottom surface of the fixed rectangular frame 3. The output end of the hydraulic cylinder 5 passes through the fixed rectangular frame 3 and extends upward to connect with the upper rectangular frame 6. Two sliding rods 2 are respectively set at the other two opposite corners of the bottom surface of the fixed rectangular frame 3. The mechanism also includes a first limiting plate, GUD, which is set at the bottom surface of the sliding rod 2. The top of the sliding rod 2 passes through the fixed rectangular frame 3 and extends upward to be fixedly connected with the upper rectangular frame 6.

[0024] In this embodiment, the output end of the hydraulic cylinder 5 drives the upward moving rectangular frame 6 to move vertically upward. The movement of the upward moving rectangular frame 6 drives the left moving rectangular frame 7 to move, thereby realizing the adjustment of the height of the cathode plate 9. While the upward moving rectangular frame 6 moves, it drives the two sliding rods 2 to move upward, providing stable support. The first limiting plate is set on the bottom surface of the sliding rod 2 to prevent the sliding rod 2 from coming out of the fixed rectangular frame 3.

[0025] Reference Figure 2 It also includes two grooves 12, which are formed on the top surface of the upward-moving rectangular frame 6. A threaded rod 11 and a guide rod 10 are respectively set in the two grooves 12. The two ends of the threaded rod 11 are rotatably connected to the groove wall of the groove 12, and the two ends of the guide rod 10 are fixedly connected to the groove wall of the groove 12. Two guide blocks 13 are respectively sleeved on the outer wall of the threaded rod 11 and the guide rod 10. The guide blocks 13 are fixedly connected to the left-moving rectangular frame 7. One end of the threaded rod 11 passes through the groove 12 and extends outward to connect to the output end of the first motor 4. The guide blocks 13 on the threaded rod 11 are threadedly connected to the threaded rod 11, and the guide blocks 13 on the guide rod 10 are slidably connected to the guide rod 10.

[0026] In this embodiment, the output end of the first motor 4 drives the threaded rod 11 to rotate. The rotation of the threaded rod 11 drives the guide block 13, the left-moving rectangular frame 7 and another guide block 13 on it to move along the horizontal direction of the guide rod 10 away from the first motor 4. This makes it easier for the operator to remove the cathode plate 9 from the electrolytic cell 1, and realizes the flexible adjustment of the height and horizontal position of the cathode plate 9, improving the automation level and ease of operation of the device.

[0027] The implementation principle of the nickel waste electrolytic recovery device in this application embodiment is as follows: During use, nickel wastewater is introduced into the electrolytic cell 1 for electrolysis. Nickel ions are reduced to nickel metal under the catalytic action of the titanium-coated anode plate and deposited on the cathode plate 9. After the electrolysis operation is completed, the output end of the hydraulic cylinder 5 first drives the upward-moving rectangular frame 6 to move vertically upward. The movement of the upward-moving rectangular frame 6 drives the left-moving rectangular frame 7 to move, thereby adjusting the height of the cathode plate 9. Then, the output end of the first motor 4 drives the threaded rod 11 to rotate, and the rotation of the threaded rod 11 drives the... Guide block 13, left-moving rectangular frame 7 and another guide block 13 move along the horizontal direction of guide rod 10 away from the first motor 4, moving cathode plate 9 out of electrolytic cell 1. Finally, the output ends of dual-axis motor 18 drive the rotating rod 21 on it to rotate. The rotation of rotating rod 21 drives the short connecting rod 20 on it to move. The movement of short connecting rod 20 drives long connecting rod 19 and scraper 14 to move up and down along the vertical direction of vertical rod 15. The scraper 14 scrapes off the nickel metal deposited on cathode plate 9, which is convenient for subsequent purification treatment.
