[0002] At present, the large round tubes of continuous casting crystallizers are all electroplated in the market by tank-type electroplating (immersion electroplating), and the large round tubes are hoisted in the plating tank for electroplating. Its main advantage is that the electroplating equipment is simple, the main body of the equipment is a DC power supply and a plating tank, the production line investment is low, and it is easy to build, so this electroplating method has been widely used. However, the specifications of the large round tubes range from Φ400mm-Φ1320mm, and the specifications themselves are large, resulting in a large floor space and tank liquid consumption of the plating tank, and a large amount of tank liquid is carried out when the tank is out of the tank; tank-type electroplating also requires the outer surface (non-electroplating surface) of the large round tube to be sealed with insulating tape. In addition, in traditional tank-type nickel plating, the plating solution is circulated internally in the plating tank, and the thickness of the upper and lower openings of the plating layer is basically the same during the electroplating process, and it is impossible to perform step-type electroplating according to the principle of using the crystallizer copper tube. Utility Model Content

[0003] In view of the above problems, the utility model proposes an assembled large round tube device for electroplating crystallizer outside the tank, which uses the inner wall of the large round tube itself as the inner wall of the plating liquid tank, and forms a plating liquid tank by combining with upper and lower pressure plates and a base, so that the plating liquid forms a circulating plating liquid in this tank, thereby realizing electroplating on the inner wall of the large round tube.

[0004] To achieve the above purpose, the following technical scheme is adopted: an assembled large round tube device for electroplating crystallizer outside the tank, including a large round tube body, an anode, an anode supporting square steel, an upper pressing plate, a lower pressing plate and a base, wherein the upper pressing plate and the lower pressing plate are annular plates, and the inner diameters of the two annular plates are respectively matched with the inner diameters of the upper and lower edges of the large round tube body, and the lower edge of the inner ring of the upper pressing plate and the upper edge of the inner ring of the lower pressing plate are respectively provided with step grooves for assembly with the upper and lower edges of the large round tube body,

The lower pressing plate is mounted on the base, so that the upper pressing plate, the large round tube body, the lower pressing plate and the base form a plating liquid tank with an opening on the upper surface.

[0006] Two support frames are arranged on the upper surface of the upper pressure plate, and the two ends of the anode support square steel are respectively installed on the two support frames. The anode is located in the large circular tube body and is concentric with it. The upper end of the anode is suspended on the anode support square steel, and a gap is left between the lower end and the bottom of the formed plating tank. A liquid outlet is left at the bottom of the plating tank, and the liquid outlet is arranged on the base. A cathode terminal plate is arranged on the base, and the cathode terminal plate is connected to the outer wall of the large circular tube body.

[0007] Furthermore, a circle of air outlet nozzles is arranged at the bottom of the plating tank, a plurality of air holes are evenly arranged on the tube wall of the air outlet nozzles, and the air outlet nozzles are externally connected to an air compression pump.

[0008] Furthermore, the gas outlet nozzle is located between the inner wall of the large circular tube body and the outer wall of the anode, and the distance between the two is equal.

[0009] Furthermore, the upper pressing plate and the lower pressing plate are connected by four sets of screw rods and are locked with bolts.

[0010] Furthermore, a circle of baffles is welded along the edge of the inner ring of the upper pressure plate.

[0011] Further, the upper end of the anode is higher than the height of the baffle.

[0012] Furthermore, the anode supporting square steel and the two supporting frames are insulated from each other.

[0013] Furthermore, a lifting lug is arranged on the upper surface of the upper pressing plate.

[0014] The utility model has the following beneficial effects: the utility model utilizes the inner wall of the large round tube as the inner wall of the plating tank, and forms a plating tank with an upper surface opening by combining with the upper and lower pressure plates and the base, and arranges a liquid outlet at the bottom of the tank, and arranges an anode support square steel on the upper pressure plate, and suspends the anode on the anode support square steel and places it in the plating tank, and passes the liquid inlet pipe directly through the upper surface opening, and connects the liquid outlet to an external circulating pump, so that a circulating plating liquid is formed in the plating tank, and the plating liquid is rapidly deposited and plated under the action of the electric field between the anode and the large round tube. Compared with the traditional tank electroplating, the floor space occupied by the plating tank, the amount of tank liquid used, and the amount of tank liquid carried out when the tank is discharged are reduced, and the insulating tape sealing link is saved, thereby saving costs. In addition, the height of the plating liquid in the electroplating tank can be achieved by controlling the amount of liquid inlet, thereby realizing step-type electroplating.

The inner diameters of the two annular plates match the inner diameters of the upper and lower edges of the large circular tube body 1 respectively. The lower edge of the inner ring of the upper pressing plate 4 and the upper edge of the inner ring of the lower pressing plate 5 are respectively provided with step grooves for assembly with the upper and lower edges of the large circular tube body 1. Four groups of symmetrical openings are processed on the upper pressing plate 4 and the lower pressing plate 5 for connecting the two together through screws 9. Two support frames 400 for installing the anode support square steel 3 and lifting ears 401 for lifting are welded on the upper surface of the upper pressing plate 4. A circle of baffles 402 are welded along the edge of the inner ring of the upper pressing plate 4 to make the tank liquid height exceed the upper end face of the large circular tube body 1 to avoid the possibility of plating leakage. A liquid outlet 600, a cathode terminal plate 7 and a circle of air outlet nozzles 8 are arranged on the base 6. The tube wall of the air outlet nozzle 8 is evenly arranged with a number of ventilation holes.

[0026] The lower pressing plate 5 is placed on the base 6, and the upper and lower edges of the large circular tube body 1 are respectively assembled on the upper pressing plate 4 and the lower pressing plate 5.

The anode 2 is hung on the anode supporting square steel 3 by a hook. The two ends of the anode supporting square steel 3 are assembled on the two supporting frames 400 of the upper pressure plate 4 and the two are insulated. The anode 2 is located in the large circular tube body 1 and is concentric with the large circular tube body 1. There is a gap between the lower end of the anode 2 and the bottom of the formed plating tank. The upper end of the anode 2 is higher than the height of the baffle 402. At the same time, it is ensured that the air outlet nozzle 8 is located between the inner wall of the large circular tube body 1 and the outer wall of the anode 2, and the distance between the two is equal.

The plating liquid is quickly deposited on the inner wall of the large circular tube body 1 under the action of the electric field between the anode 2 and the large circular tube body 1, completing the nickel plating work on the electroplating surface of the large circular tube. By adjusting the liquid inlet parameters, step-type electroplating can be achieved. During the electroplating process, compressed air is injected, and the compressed air enters the plating liquid from the vent hole of the air outlet nozzle 8, so that the plating liquid surges when circulating in the plating liquid tank to avoid pinholes on the electroplating surface.
