[0018] Step 1: discharge the wastewater generated by the electroplating of metal products into the interior of the box through the water inlet pipe, and add chemicals for sewage treatment to the interior of the box;

[0019] Step 2: Start the linear motor to drive the connection frame to rise and fall, thereby driving the frame to rise and fall, and control the lifting distance of the frame through the positioning sensor. When the frame rises and falls, the sewage inside the box will surge through the through slot, so that the sewage inside the box and the chemical agent are mixed more fully;

[0022] Step 5: After the suspended solids are treated, the treated sewage is discharged to the next process through the first drain pipe. At this time, the collection box is pulled out, and the sludge on the horizontal plate will fall to the bottom of the inner wall of the collection box during the extraction process.

[0023] Step 6. Start the water pump to flush the inside of the box with clean water in the water tank through the water pipe and branch pipe. At the same time, pull the water gun to flush the gaps in the box. After flushing, store the water gun by rotating the reel.

[0024] The present invention adopts the above technical solution to bring the following beneficial effects:

[0025] 1. The electroplating wastewater treatment equipment and method for metal products can drive the frame to move up and down by setting a guide rail, a linear motor, and a connecting frame. The through groove can drive the sewage inside the box to surge when the frame moves up and down, so that the sewage can better react with the chemical agent. The electromagnet and the magnetic plate can drive the baffle to move, thereby covering the through groove, which is convenient for collecting and treating suspended matter in the sewage. At the same time, the drainage hole can effectively separate the sewage and suspended matter, making the collection of suspended matter more stable and avoiding the influence of suspended matter on subsequent sewage treatment.

[0026] 2. The electroplating wastewater treatment equipment and method for metal products can collect the sludge generated during the sewage treatment process by setting a horizontal plate and a collecting box to prevent the sludge from affecting subsequent sewage treatment. The excess water in the sludge can be removed by setting a drain port and a drain trough to facilitate subsequent sludge treatment.

[0027] 3. The electroplating wastewater treatment equipment and method for metal products can compact the sludge in the collection box by setting a limit rod, a movable rod, a second spring and a pressure plate, thereby effectively reducing the volume of the sludge, allowing the collection box to collect more sludge and facilitating subsequent sludge treatment.

[0028] 4. The electroplating wastewater treatment equipment and method for metal products facilitates flushing of the interior of the box by arranging a water tank, a water pump, a water pipe and a branch pipe, making the interior of the box cleaner and convenient for subsequent reuse. By arranging a water gun, the gaps inside the box can be treated to improve the flushing effect. By arranging a reel, the metal of the water gun can be stored, thereby facilitating the use of the water gun. BRIEF DESCRIPTION OF THE DRAWINGS

The branch pipe (44) is fixedly connected to the bottom of the top plate, and one end of the branch pipe (44) is connected to the side of the water pipe (43).

8. The electroplating wastewater treatment equipment for metal products according to claim 7, characterized in that: A reel (45) is rotatably connected to one side of the water tank (41), and a water gun (46) is wound around the reel (45). One end of the water gun (46) is connected to the water tank (41).

9. The electroplating wastewater treatment equipment for metal products according to claim 8, characterized in that: One side of the box body (1) is connected to a water inlet pipe (5), and the other side of the box body (1) is connected to a first drain pipe (6) and a second drain pipe (7), wherein the first drain pipe (6) is located above the partition (31) and the second drain pipe (7) is located below the partition (31).

10. A method for treating electroplating wastewater of metal products, characterized in that: The electroplating wastewater treatment equipment for metal products according to claim 9 comprises the following steps: Step 1: discharge the wastewater generated by the electroplating of metal products into the interior of the box (1) through the water inlet pipe (5), and add a chemical agent for wastewater treatment to the interior of the box (1); Step 2: Start the linear motor (22) to drive the connecting frame (23) to move up and down, thereby driving the frame (24) to move up and down, and control the lifting distance of the frame (24) through the positioning sensor (217). When the frame (24) moves up and down, the sewage inside the box (1) will be stirred through the through groove, so that the sewage inside the box (1) and the chemical agent are mixed more fully; Step 3: After the sewage reacts with the chemical agent, suspended matter and sludge will be generated. The suspended matter will be suspended in the sewage, while the heavier sludge will sink to the horizontal plate (34). When the frame (24) descends, the moving rod (214) will be driven down through the pressing block, thereby driving the pressing plate (216) to descend, thereby squeezing the sludge on the horizontal plate (34); Step 4: After the reaction between the sewage and the chemical agent is completed, the frame (24) is lowered to the lowest end by the linear motor (22), and the electromagnet (211) is started, so that the electromagnet (211) drives the magnetic plate (210) to move to the left, thereby driving the baffle (27) to move to the left. At this time, the linear motor (22) is started again to drive the frame (24) to rise. The rising frame (24) will collect the suspended matter in the sewage inside the frame (24), and the suspended matter will be collected, and the treated sewage will be discharged to the bottom through the drainage hole (28); Step 5: After the suspended solids are treated, the treated sewage is discharged to the next process through the first drain pipe (6). At this time, the collecting box (32) is drawn out, and the sludge on the horizontal plate (34) falls to the bottom of the inner wall of the collecting box (32) during the extraction process. At this time, the excess water in the sludge is discharged into the interior of the box body (1) through the drain port (35) on the collecting box (32) through the drain trough (38), and the excess water is discharged through the second drain pipe (7); Step 6: Start the water pump (42) to flush the inside of the box body (1) with clean water in the water tank (41) through the water pipe (43) and the branch pipe (44), and at the same time, pull the water gun (46) to flush the gap of the box body (1). After the flushing is completed, the water gun (46) is stored by rotating the reel (45).
