Description

Technical Field

[0001] This utility model relates to the field of nickel-based alloy production technology, specifically a wet multi-stage internal circulation purification device. Background Technology

[0002] Nickel alloys are alloys composed of nickel as the base and other elements. Nickel has good mechanical, physical and chemical properties. Adding appropriate elements can improve its oxidation resistance, corrosion resistance, high temperature strength and some physical properties. Nickel alloys can be used as materials for electron tubes, precision alloys (magnetic alloys, precision resistance alloys, electrothermal alloys, etc.), nickel-based high-temperature alloys, nickel-based corrosion-resistant alloys and shape memory alloys, etc. Nickel-based alloys need to be electrolyzed during production.

[0003] Publication No. CN 220450344 U discloses an electrolytic cell for zinc-nickel alloy rack plating, including a fixed base. An electrolytic cell is fixedly installed in the middle of the fixed base. Hydraulic rods are installed on both sides of the top of the fixed base. A movable base is fixedly connected to the top of the two hydraulic rods. A connecting base is fixedly connected to the bottom of the movable base. The connecting base matches the size of the electrolytic cell. Multiple rack plating rods are fixedly installed at the bottom of the connecting base. A purification mechanism for purifying harmful gases generated by the electrolytic cell is installed on the top of the movable base. The top of the electrolytic cell is sealed by a sealing ring inside the sealing groove, so that the gas will not overflow during electrolysis. It can also prevent electrolyte solution from splashing when the workpiece is placed into the electrolytic cell, reducing safety hazards. The gas generated during electrolysis is introduced into a storage tank by an air pump. After being purified by a filter plate, an activated carbon layer and the corresponding liquid in the storage tank, the harmful gases are purified, reducing air pollution during electrolysis and reducing the harm of harmful gases to workers.

[0004] However, this electrolysis device has the following shortcomings: while it can electroplate nickel alloys, it often cannot purify the electrolyte after repeated use, resulting in a large number of impurities that affect the electroplating effect on nickel alloys. In addition, it is inconvenient to load and unload nickel-based alloys during use, which affects the overall production efficiency.

[0005] Therefore, this utility model provides a wet multi-stage internal circulation purification device to solve the above problems. Utility Model Content

[0028] Example 2:

[0029] Please see Figures 1 to 4 This embodiment provides a technical solution based on Embodiment 1: Multiple partitions 14 are fixedly connected inside the electrolysis tank 3. Multiple seepage holes 15 are opened on the partitions 14, and a polymer membrane cloth 16 is provided on the partitions 14. Multiple titanium baskets 17 are arranged inside the electrolysis tank 3, with the titanium baskets 17 and partitions 14 alternating.

There is a height difference between each pair of adjacent anode plates 18, and multiple connecting ports 19 are opened on each of the three corresponding anode plates 18. Multiple cathode rods 20 are fixedly connected inside the purification tank 2. An overflow bend 21 is connected through one side of the electrolysis tank 3, and multiple infusion pipes 22 are connected through the overflow bend 21.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] Working principle: During use, the operator places the nickel-based alloy product to be electroplated in the placement rack 5, then hoists it to the bottom of the lifting plate 4. The drive motor 11 is then started, which drives two active bevel gears 13 to rotate via the transmission shaft 12. The active bevel gears 13 drive the driven bevel gears 10 meshing with them to rotate, which in turn drives the connected threaded rod 8 to rotate. The threaded rod 8 drives the threaded telescopic sleeve 9, which is connected to it, to descend, causing the lifting plate 4 to descend until the nickel-based alloy in the placement rack 5 is immersed in the electrolyte. After the electroplating process is complete, the process is reversed to remove the product. Simultaneously, when purification of the electrolyte in the electrolysis tank 3 is required, the electrolyte in the electrolysis tank 3... The electrolyte overflows into the purification tank 2 through the overflow bend 21. At this time, the appropriate switch valve 23 is opened according to the corresponding purification requirements, so that the electrolyte in the overflow bend 21 enters the purification tank 2. The electrolyte enters the purification tank 2 through the infusion pipes 22 at different positions, and its flow path is different, so that it undergoes different degrees of purification. The electrolyte flows through the anode plates 18 at different heights and the connecting port 19 in the purification tank 2. At the same time, the anode plates 18 and the cathode rods 20 can purify it. Then, the filter pump 24 is started. The filter pump 24 delivers the purified electrolyte to the ion exchanger 26 through the return pipe 25, and then flows back to the electrolysis tank 3 through the circulation pipe 27 to complete the circulation.
