[0029] The filtering mechanism includes a liquid pump 14 and a filter box 15 fixedly installed on one side of the electroplating box 1. The liquid inlet and liquid outlet ends of the liquid pump 14 are fixedly connected to a liquid suction pipe 16 and a liquid discharge pipe 17 respectively. The other end of the liquid suction pipe 16 passes through the electroplating box 1 and extends to a position near the bottom end of the electroplating box 1. The other end of the liquid outlet pipe is fixedly connected to the middle position of the top of the filter box 15. A filter plate 18 is fixedly connected to the inner wall of the filter box 15.

A driving gear 26 is meshed on the outer surface of the driving rack 25 , and the driving gear 26 is fixedly sleeved on one end of the threaded rod 21 .

[0032] Working principle: When ferrous metal smelting rolled products need to be electrogalvanized, the staff first places the ferrous metal smelting rolled products to be processed on the U-shaped placement rack 5, and then starts the electric telescopic rod 11 to extend its telescopic end, driving the vertical rod 12 and the clamping plate 13 to move downward until the bottom of the clamping plate 13 abuts against the top of the ferrous metal smelting rolled products placed on the U-shaped placement rack 5, thereby clamping and fixing the ferrous metal smelting rolled products through the clamping plate 13, improving the stability of the ferrous metal smelting rolled products and facilitating the subsequent immersion of the ferrous metal smelting rolled products in the electroplating solution;

[0033] Then, the servo motor 6 is started, and the output end of the servo motor 6 rotates clockwise, driving the reel 7 to rotate and unwind the rope 8, thereby causing the protective plate 3 to move downward, and the cooperation of the slide rail 9 and the slider 10 can limit the protective plate 3, thereby improving the stability of the protective plate 3 during movement, and the downward movement of the protective plate 3 drives the U-shaped placement rack 5 and the ferrous metal smelting and rolling products to move downward synchronously until the ferrous metal smelting and rolling products are immersed in the electroplating solution in the electroplating tank 2, and the bottom of the protective plate 3 overlaps the top of the electroplating box 1, and the opening at the top of the electroplating box 1 is blocked by the protective plate 3 to play a splash-proof effect and prevent the electroplating solution from splashing out; then the ferrous metal smelting and rolling products are connected to the cathode of the external power supply, and the zinc plate 27 is connected to the anode of the external power supply, so that the zinc ions in the zinc plate 27 are attached to the surface of the ferrous metal smelting and rolling products, thereby realizing the galvanizing operation of the ferrous metal smelting and rolling products;

[0034] When the galvanizing treatment of the ferrous metal smelting rolled products is completed, the servo motor 6 is started, and the output end of the servo motor 6 rotates counterclockwise, driving the reel 7 to rotate and reel the rope 8, thereby lifting the protective plate 3 upward, and driving the U-shaped placement rack 5 and the ferrous metal smelting rolled products to move upward synchronously until the U-shaped placement rack 5 moves to a position close to the top of the electroplating box 1, making it convenient for the staff to take and place the ferrous metal smelting rolled products on the U-shaped placement rack 5, saving time and labor, and effectively improving the efficiency of galvanizing the ferrous metal smelting rolled products;

[0035] During the galvanizing process of the ferrous metal smelting rolled products, the liquid pump 14 is simultaneously turned on, and the liquid pump 14 extracts the plating liquid in the plating tank 2 through the liquid extraction pipe 16, and discharges the plating liquid into the filter box 15 through the liquid discharge pipe 17. The plating liquid in the filter box 15 drips onto the filter plate 18, and the impurities in the plating liquid are filtered by the filter plate. The plating liquid filtered by the filter plate is then returned to the plating tank 2 through the reflux pipe 20, thereby realizing the circulation filtration of the plating liquid in the plating tank 2, so as to reduce the impurity content in the plating liquid, and effectively improve the electroplating effect;

[0036] During the up and down movement of the protective plate 3, the support plate 24 and the driving rack 25 can be driven to move up and down synchronously, and the movement of the driving rack 25 drives the driving gear 26 engaged with it to move, thereby driving the threaded rod 21 to rotate, so that the threaded block 22 and the scraper 23 move back and forth along the axial direction of the threaded rod 21. The movement of the scraper 23 can scrape the impurities accumulated on the top of the filter plate 18 into the collection chamber, and through the setting of the filter plate 2 19, the electroplating liquid doped with impurities can be drained, that is, the electroplating liquid can pass through the filter plate 2 19 and enter the electroplating tank 2 from the reflux pipe 20, while the impurities are intercepted by the filter plate 2 19.
