[0002] Electroplating is a process that uses the principle of electrolysis to deposit a layer of metal film on the surface of metal or other conductive materials.

[0003] The electroplating process involves the knowledge of electrochemistry. Through electrolysis, a thin layer of metal or alloy is formed on the surface of the target object. This thin layer can provide a variety of functional improvements, such as improving wear resistance, conductivity, reflectivity and corrosion resistance, and is also used to enhance aesthetics.

[0004] Electroplating technology is widely used in industry and daily life, such as in coin manufacturing, automotive parts, electronic components, decorative items, etc. According to different needs, suitable plating materials such as zinc plating, copper plating, nickel plating, chrome plating, etc. can be selected to achieve the desired effect.

[0005] On the rack plating line, usually after electroplating or other surface chemical treatment, some chemical stock solutions will remain on the plated parts. These remaining chemical stock solutions will also enter the next cleaning tank along with the plated parts. As the concentration of the chemical stock solution in the cleaning tank gradually increases, the cleaning solution (clean water) in the cleaning tank needs to be replaced to maintain a good cleaning effect.

The filtering tank is divided into two upper and lower cavities. The upper cavity is a sewage receiving cavity, and the lower cavity is a clean water receiving cavity. A filter plate is arranged between the sewage receiving cavity and the clean water receiving cavity.

[0008] Furthermore, a diversion baffle is provided in the middle of the sewage receiving chamber, and a rotating shaft is provided on the side of the diversion baffle close to the clean water receiving chamber. The diversion baffle can rotate in the sewage receiving chamber with the rotating shaft as the axis.

[0009] Furthermore, there are two filter plates, which are disposed on both sides of the rotating shaft of the diverter baffle.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] An environmentally friendly electroplating tank includes an electroplating tank, a filtering tank and a cleaning tank. The electroplating tank is arranged at the front end, the cleaning tank is arranged at the end, and the filtering tank is arranged between the electroplating tank and the cleaning tank. The filtering tank is divided into two upper and lower cavities. The upper cavity is a sewage receiving cavity, and the lower cavity is a clean water receiving cavity. A filter plate is arranged between the sewage receiving cavity and the clean water receiving cavity. A diverter baffle is arranged in the middle of the sewage receiving cavity. A rotating shaft is arranged on the side of the diverter baffle close to the clean water receiving cavity. The diverter baffle can rotate in the sewage receiving cavity with the rotating shaft as the axis. There are two filter plates, which are arranged on both sides of the rotating shaft of the diverter baffle. The filter plate includes a filter plate bracket and a filter plate body. The filter plate bracket is fixedly installed in the filter tank, and the filter plate body is placed in the filter plate bracket. The filter plate bracket includes a side bracket and a middle bracket. The side bracket is arranged on both sides of the filter tank, and the middle bracket is arranged in the middle of the filter tank. The side bracket is in a "U" shape, and the middle bracket is in an "I" shape. The filter tank has two openings on the side for pulling out the filter plate body, and the filter plate body can be installed or pulled out from the filter tank through the openings. Guide plates are provided on both sides of the top of the filter tank, one end of the guide plate is fixedly connected to the side walls on both sides of the top of the filter tank, and the other end is inclined downward. A rotating shaft motor is also provided on the outer wall of the filter tank, and the rotating shaft motor is connected to the rotating shaft of the diverter baffle. A pipeline is also provided between the clean water storage chamber and the cleaning tank, and a water pump is provided in the pipeline.

[0028] The actual application process is as follows: the electroplated parts leave the electroplating tank and slowly pass over the filter tank. When passing through, the chemical stock solution hanging on the surface of the electroplated parts drips into the filter tank. At this time, the diverter baffle set in the middle of the filter tank swings to one side and tilts. For example, when the diverter baffle tilts to the right side as shown in the figure, the chemical stock solution drips on the left filter plate. If the diverter baffle tilts to the left side as shown in the figure, the chemical stock solution drips on the right filter plate. In other words, one side of the filter plates on the left and right sides is always in use, and the other side is in an empty state. The filter plate on the empty side is used for easy replacement and maintenance. The filter plate can separate the clean water in the electroplating solution, and the separated clean water flows into the clean water storage chamber. The bottom of the clean water storage chamber is connected to the top pipeline of the cleaning tank. When the clean water in the clean water storage chamber reaches a certain amount, it is transported to the cleaning tank through the water pump in the pipeline.

[0029] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
