The output end of the reciprocating drive motor 12 is connected to the top of the threaded rod 13. The outer wall of the threaded rod 13 is screwed to the inner wall of the threaded pipe 10. The input end of the reflux cylinder 1 is connected to one side of the input pipe 2. The tail end of the input pipe 2 is connected to the absorption head 5. A connecting plate 4 is also connected to the input pipe 2. One side of the top of the connecting plate 4 is connected to the stirring rod 5. The bottom end of the motor 6 is connected to the agitator 6, and the output end of the agitator 6 is connected to the top end of the agitator 7. Multiple sets of agitator blades 8 are connected to the outside of the agitator 7. The output end of the reflux cylinder 1 is connected to a set of filter mechanisms via the output pipe 3. When reflux is performed, the absorber head 5 and the tail of the output pipe 3 are inserted into the electroplating tank liquid. Then, the agitator 6 runs, driving the agitator 7 to rotate the multiple sets of agitator blades 8, stirring the electro-hydraulic liquid and mixing the internal sediment evenly. The reciprocating drive motor 12 runs, causing the threaded rod 13 to rotate. Under the connection of the support frame 11, the threaded rod 13 is screwed into the threaded pipe 10, causing the threaded pipe 10 to drive the piston 9 to rise, creating a negative pressure inside the reflux cylinder 1. The mixed liquid is then sucked into the reflux cylinder 1 through the absorber head 5 and the output pipe 3. Then, the reciprocating drive motor 12 reverses, discharging the liquid through the output pipe 3 and filtering it through the filter mechanism.

[0025] It also includes a one-way valve 14. A set of one-way valves 14 is provided at the connection between the return cylinder 1 and the input pipe 2 and the output pipe 3.

[0030] In summary, when using a reflux device for cleaning an electroplating tank, the absorption head 5 and the tail of the output pipe 3 are inserted into the electroplating tank liquid during reflux. Then, the stirring motor 6 drives the stirring rod 7, causing multiple sets of stirring blades 8 to rotate, agitating the electroplating liquid and mixing the internal sediment evenly. The reciprocating drive motor 12 then drives the threaded rod 13 to rotate. Under the connection of the support frame 11, the threaded rod 13 is screwed into the threaded pipe 10, causing the threaded pipe 10 to drive the piston 9 upward, creating negative pressure inside the reflux cylinder 1. This allows the mixed liquid to be drawn into the reflux cylinder 1 through the absorption head 5 and the output pipe 3. Afterward, the mixture is then... The drive motor 12 reverses, discharging the wastewater through the output pipe 3. The one-way valve 14 allows for one-way flow between the input pipe 2 and the output pipe 3, preventing backflow. When the filter cartridge 21 is installed inside the sleeve 18, the handle 22 is screwed closed on the outside of the external threaded opening 19 via the internal threaded cap 17. Wastewater can be filtered and collected by the filter cartridge 21 when it is discharged from the output pipe 3, and then discharged through the sleeve 18 and the drain hopper 20.
