Description

Technical Field

[0001] The utility model relates to the field of grounding steel sheet surface treatment, in particular to a grounding steel sheet surface treatment device. Background Art

[0002] The grounding steel sheet is a component that connects the power system to the earth. It is one of the very important protection measures in the power system. It is connected to the power system and realizes the grounding of the circuit by connecting to the earth. When the circuit is energized, the grounding steel sheet can introduce overvoltage or current into the ground, eliminating the potential danger of current. It can also prevent damage to electrical equipment and electric shock to personnel. The surface of the grounding steel sheet is nickel-plated to increase the bonding force between the steel sheet and the FPC and improve the stability of the grounding of the steel sheet. The surface of the steel sheet after nickel plating is horizontally sandblasted to further increase the contact area of ​​the steel sheet surface, which can further improve the bonding force between the grounding steel sheet reinforcement and the FPC.

[0003] Existing grounded steel sheet surface treatment devices, such as the nickel plating pool for electroplating production proposed in patent application number "CN202021732367.X", have the technical effect of centralized recovery of waste gas generated during the nickel plating process through structures such as nickel plating boxes, exhaust pipes, exhaust boxes, and exhaust holes, thereby effectively avoiding the problem of waste gas escaping from the nickel plating pool to the outside.

[0004] However, the exhaust gas recovery range of the exhaust box is limited, the exhaust gas recovery effect is poor, and the electroplating solution will oxidize and produce impurities when in contact with air. More impurities affect the electroplating effect. Therefore, a grounded steel sheet surface treatment device is proposed. Utility Model Content

[0023] A surface treatment device for a grounded steel sheet comprises a box body 1, wherein a bracket 13 is fixedly connected to the upper end of the box body 1, a fixing assembly for mounting a grounded steel plate is fixedly connected to the lower end of the bracket 13, a groove 2 is provided on one side of the upper end of the box body 1, a blowing box 3 is clamped in the groove 2, an exhaust box 4 is clamped on the other side of the upper end of the box body 1, the blowing box 3 is opposite to the exhaust box 4, a liquid outlet 5 is penetrated through the side wall of the box body 1 below the exhaust box 4, and a filtering mechanism is provided at a position below the liquid outlet 5 inside the side wall of the box body 1.

[0024] like Figure 1-Figure 4 As shown, the fixing component is supported by the bracket 13, and the fixing component is hung and installed above the box body 1, which is convenient for hanging the grounding steel plate for electroplating. The blowing box 3 and the exhaust box 4 are installed opposite to each other at the upper end of the box body 1. The blowing box 3 and the exhaust box 4 are respectively connected to the external air outlet equipment and the exhaust equipment. The blowing box 3 blows the waste gas generated by electroplating to the exhaust box 4, and the waste gas collection range becomes larger, thereby improving the waste gas collection effect of the exhaust box 4. The blowing box 3 will blow the surface of the electroplating liquid, and blow the impurities generated by oxidation on the surface of the electroplating liquid to the liquid outlet 5, so that the impurities are discharged from the box body 1 through the liquid outlet 5, thereby reducing the impurities in the electroplating liquid and preventing multiple impurities from affecting the electroplating effect. The surface of the grounding steel sheet after nickel plating is horizontally sandblasted to increase the contact area of ​​the surface of the grounding steel sheet, which can improve the bonding strength between the grounding steel sheet reinforcement and the FPC.

[0025] The bracket 13 is located in the middle position above the box body 1, the bottom wall of the liquid outlet 5 is located below the bottom wall of the groove 2, the top of the filter mechanism is connected to the liquid outlet 5, and the bottom of the filter mechanism is connected to the inside of the box body 1. The bottom wall of the box body 1 is fixedly connected to the heating tube 11.

[0026] like Figure 4 As shown, the electroplating liquid is added until it is flush with the bottom wall of the liquid outlet 5, so that impurities can flow out of the box 1 through the liquid outlet 5, and the filtering mechanism can filter and recover the electroplating liquid carrying impurities.

[0027] The filtering mechanism includes a cavity 6, which is opened inside the side wall of the box body 1. The upper end of the inner wall of the cavity 6 is connected to the bottom wall of the liquid outlet 5 and has multiple groups of coarse filter holes 8. The inner wall of the cavity 6 is connected to the inner wall of the box body 1 and has a connecting port 7.

[0028] like Figure 1-Figure 4 As shown, the electroplating liquid carrying impurities flows out of the housing 1 through the liquid outlet 5, and the coarse filter hole 8 coarsely filters the electroplating liquid, discharges larger impurities in the electroplating liquid carrying impurities from the housing 1, and the electroplating liquid carrying smaller impurities enters the cavity 6.

[0029] A fine filter plate 9 is clamped on the inner wall of the cavity 6, and the side wall of the fine filter plate 9 fits with the inner wall of the cavity 6. The fine filter plate 9 is located between the coarse filter hole 8 and the connecting port 7. One end of the fine filter plate 9 passes through the side wall of the box body 1, and a fixing plate 10 is fixedly connected to one end of the fine filter plate 9 passing through the box body 1.

[0030] like Figure 1-Figure 4 As shown, the fine filter plate 9 finely filters the plating liquid carrying smaller impurities to remove impurities in the plating liquid. The impurities after fine filtration are mixed with the plating liquid in the box 1 through the connecting port 7, and the plating liquid is recycled.

A servo motor 14 is fixedly connected to the upper end of the bracket 13, and the output end of the servo motor 14 is fixedly connected to the upper end of the screw rod 15. A movable plate 17 is threadedly connected to the screw rod 15, and the movable plate 17 is slidably connected to the fixing rod 16.

[0032] like Figure 1-Figure 2 As shown, the servo motor 14 drives the screw rod 15 to rotate, and the screw rod 15 rotates to drive the movable plate 17 to rise and fall, and the fixed rod 16 limits the position of the movable plate 17, so that the movable plate 17 can only rise and fall along the fixed rod 16 and will not rotate.

[0033] A U-shaped frame 18 is fixedly connected to the lower end of the movable plate 17 , a screw 19 is threadedly connected to one side of the U-shaped frame 18 , and a clamping plate 20 is fixedly connected to one end of the screw 19 located inside the U-shaped frame 18 , and the clamping plate 20 is squeezed and matched with the inner wall of the U-shaped frame 18 .

[0035] The working principle of the grounding steel sheet surface treatment device provided by the utility model is as follows:

[0036] The fixing component is supported by the bracket 13 and hung above the box body 1, which is convenient for hanging the grounded steel plate for nickel electroplating.
