The waste liquid treatment tank 41 is connected to the cleaning tank 31 and is used to receive the waste water after cleaning in the cleaning tank 31 .

[0021] It should be noted that: in the device, an electroplating unit 2, a cleaning unit 3 and a waste liquid treatment unit 4 are arranged on the fixing frame 1, that is, the electroplating treatment of the bearing retainer body 5 is realized by the electroplating unit 2. After the electroplating operation is completed, the bearing retainer body 5 can be transferred to the cleaning unit 3, and the electroplating liquid on the surface of the bearing retainer body 5 can be washed away by clean water, and the sewage generated during the flushing process can be directly introduced into the waste liquid treatment unit 4, and the waste liquid treatment unit 4 can intercept impurities in the sewage, and then extract a small amount of electroplating liquid contained in the sewage to realize the recovery and reuse of the electroplating liquid; A pneumatic stirring element is also provided inside the electroplating tank 21. The pneumatic stirring element introduces airflow into the electroplating tank 21. The airflow can directly act on the electroplating liquid, thereby promoting the flow of the electroplating liquid. That is, the electroplating liquid is continuously stirred by the airflow to improve the efficiency of electroplating.

[0022] In the embodiments of the present invention, please refer to Figure 2 A plurality of first bottom brackets 22 are fixed at the bottom of the electroplating tank 21, and a first fixing rod 23 for penetrating the bearing retainer body 5 is vertically fixed to the upper end of the first bottom bracket 22, and adjacent bearing retainer bodies 5 are separated by a first partition plate 24; The first fixing rod 23 is an electrode rod.

In this process, a first partition plate 24 needs to be added between the two bearing holder bodies 5 for separation to ensure the comprehensiveness of the electroplating operation; It should also be noted that the electroplating solution used in the electroplating operation is a solution of the metal salt to be plated.

[0024] In the embodiments of the present invention, please refer to Figure 2 and Figure 3 The pneumatic stirring element includes a ventilation guide pipe 25, the ventilation guide pipe 25 is externally connected to an air pump, and a plurality of rotary jet structures 26 are installed on the ventilation guide pipe 25; The rotary jet structure 26 includes a connecting pipe 261, which is rotatably mounted on the ventilation guide pipe 25 through a rotary sealing joint. A spiral blade 262 is fixed inside the connecting pipe 261, and a nozzle 263 is fixed at the other end of the connecting pipe 261. The nozzle 263 has a plurality of eagle-beak-shaped spray hole structures.

[0025] It should be noted that: for the pneumatic stirring element, the ventilation guide tube 25 is externally connected to an air pump to introduce gas, and then the gas enters the connecting tube 261 through the ventilation guide tube 25, and the connecting tube 261 has a spiral blade 262 inside, so a torque will be generated on the connecting tube 261 during the rapid flow of air. At the same time, the connecting tube 261 and the ventilation guide tube 25 are connected by a rotary sealing joint, that is, the ventilation guide tube 25 can rotate, and when the gas is ejected from the nozzle 263, it can generate a thrust on the electroplating liquid, and the nozzle 263 itself will also generate a thrust on the electroplating liquid when it rotates, so as to achieve stirring of the electroplating liquid and keep the electroplating liquid in a flowing state, thereby improving the electroplating effect on the bearing retainer body 5, and for the rotary jet structure 26, the kinetic energy driving its rotation is the kinetic energy of the converted flowing gas, so in actual use, no excess energy consumption will be generated, which has the effect of energy saving and further improves the practicality of the device.

[0026] In the embodiments of the present invention, please refer to Figure 4 and Figure 5 A plurality of rotatable second bottom brackets 32 are installed at the bottom of the cleaning tank 31, and a second fixing rod 33 for passing the bearing retainer body 5 is vertically fixed to the upper end of the second bottom bracket 32, and adjacent bearing retainer bodies 5 are separated by a second partition plate 34; A driving mechanism 36 is also installed at the lower end of the cleaning tank 31 to drive the second base 32 to rotate; The driving mechanism 36 includes a motor 361 fixed inside the cleaning tank 31, and the output end of the motor 361 extends into the cleaning tank 31 and is fixed concentrically to one of the second bottom brackets 32; A driving sprocket 362 is also fixed on the output shaft of the motor 361, and a driven sprocket 364 is arranged on one side of the driving sprocket 362. The driving sprocket 362 and the driven sprocket 364 are connected by a transmission chain 365. A concentric connecting shaft 363 is also fixed on the driven sprocket 364. The connecting shaft 363 is rotatably connected to the cleaning tank 31, and also extends to the inside of the cleaning tank 31 and is concentrically fixed to the remaining second base 32.

[0027] It should be noted that after the electroplating operation on the bearing retainer body 5 is completed, it can be transferred to the inside of the cleaning tank 31. The installation method inside the cleaning tank 31 is the same, and the second base 32 can be rotated, thereby mobilizing the bearing retainer body 5 to rotate together; at the same time, a water pump is used to introduce clean water into the water guide pipe 35, and the water guide pipe 35 has a plurality of spray holes, and the bearing retainer body 5 is fully rinsed with clean water; When the second base supports 32 are driven to rotate by the driving mechanism 36, the motor 361 can directly drive one of the second base supports 32 to rotate; at the same time, under the transmission action of the sprocket and the chain, the connecting shaft 363 can be driven to rotate, and the connecting shaft 363 and the remaining second base supports 32 are concentrically fixed, thereby driving the remaining second base supports 32 to rotate, thereby driving the bearing retainer body 5 to rotate together.

[0028] In the embodiments of the present invention, please refer to Figure 1 and Figure 6 A liquid inlet is arranged at the side of the waste liquid treatment tank 41 and near the top, and a liquid storage port is arranged at the bottom. A horizontally arranged grid is fixed near the center of the waste liquid treatment tank 41, and a filter layer 42 is detachable on the grid. An electric heater 43 is installed at the bottom of the waste liquid treatment tank 41; Soft magnets are fixed on the opposite sides of the filter layer 42 and the mesh frame, so that the filter layer 42 is magnetically fixed on the mesh frame; Meanwhile, a diversion pump 6 is also installed on the fixing frame 1 , and the output end of the diversion pump 6 is connected to the inside of the cleaning tank 31 through a pipeline, and the output end is connected to the liquid inlet of the waste liquid treatment tank 41 through a pipeline.

[0029] It should be noted that: a diversion pump 6 is arranged between the waste liquid treatment tank 41 and the cleaning tank 31, and the diversion pump 6 is used to extract the sewage in the cleaning tank 31 and introduce it into the waste liquid treatment tank 41. A filter layer 42 is provided inside the waste liquid treatment tank 41, and the filter layer 42 is used to separate the solid impurities in the sewage, and the liquid is concentrated at the bottom of the waste liquid treatment tank 41. An electric heater 43 is arranged at the bottom. When the sewage is heated, the water is evaporated to achieve the separation of the electroplating liquid; The filter layer 42 is fixed to the mesh frame by magnetic attraction, so it is convenient to disassemble it. When the filter layer 42 needs to be deeply cleaned, it can be directly removed from the mesh frame, so its installation and disassembly operations are very simple; It should also be noted that the filter layer 42 is preferably a metal filter structure, which has better high-temperature performance. Therefore, when the sewage is evaporated by the electric heater 43, the filter layer 42 itself is less affected and has a longer service life.

[0030] The specific usage process of the device is as follows: (1) Electroplating operation; First, the bearing retainer body 5 is sleeved on the first fixing rod 23. After being fixed, the plating liquid is introduced into the inside of the plating tank 21. At the same time, the gas is introduced into the inside of the ventilation guide tube 25 by using an air pump, and then discharged from the nozzle 263. The gas can directly act on the plating liquid to push the plating liquid to make it flow; at the same time, when the air flow passes through, the nozzle 263 will also rotate together, and the plating liquid can also be stirred during the rotation process, thereby improving the flow effect of the plating liquid and improving the plating efficiency of the bearing retainer body 5 (the gas introduced into the ventilation guide tube 25 can also be a high-temperature gas, so as to stir the plating liquid at a high temperature); (2) Flushing operation; After the electroplating operation on the bearing retainer body 5 is completed, it is transferred to the cleaning tank 31, and then the second base 32 is driven to rotate by the driving mechanism 36, thereby driving the bearing retainer body 5 to rotate together. At the same time, a water pump is used to introduce clean water into the water guide pipe 35 to rinse the bearing retainer body 5. (3) Sewage treatment; After the flushing operation of the bearing retainer body 5 is completed, the sewage in the cleaning tank 31 is pumped out by the diversion pump 6 and introduced into the waste liquid treatment tank 41. The sewage passes through the filter layer 42, and the filter layer 42 is used to separate the solid impurities in the sewage. Then, the sewage is heated by the electric heater 43, and the water is removed by physical evaporation to obtain the residual electroplating liquid, which is then re-introduced into the electroplating tank 21. The evaporated water overflows the waste liquid treatment tank 41 through the filter layer 42.
