Electric heating tube electroplating tank and a shielding body

Electroplating device, comprising an electroplating bath and a shielding body. The electroplating tank has a bottom wall and a side wall that is vertically connected to the bottom wall, and the bottom wall and side wall form an electroplating space. The shielding body is placed in the electroplating space and installed on the side wall, and at least one opening is opened on the shielding body. The electroplating device of this utility model is shielded by a shielding body, so that the electroplating solution can freely flow in the area corresponding to the opening of the shielding body of the metal part to be plated, while it cannot freely flow in the area where the shielding body covers the metal part to be plated, thereby reducing the thickness of the metal coating in the area where the shielding body covers the metal part to be plated and saving electroplating materials.

1. Energy conservation

1.1 Renovation of inefficient coal-fired industrial boilers. For old boilers that have not yet been retrofitted, technologies such as circulating fluidized bed and pulverized coal combustion should be used to replace existing small and medium-sized coal-fired boilers.

1.2 Update silicon rectifiers with outdated design, outdated structure, and low energy conversion efficiency.

1.3 Check and improve the DC current copper busbar. If the diameter is too small, the resistance is high, and the copper busbar is prone to heat generation, it should be updated and thickened, and the joints should be tightly sealed to minimize electrical energy consumption caused by resistance.

1.4 To improve the opening rate of the barrel wall for barrel plating. Nowadays, the wall opening rate of manually punched rolling barrels is only about 10%. This low opening rate is equivalent to creating a barrier in the plating solution that hinders the passage of power lines. Due to the inability of the current to pass smoothly, the voltage of the tank increases, and some nickel plating tanks even have a voltage of over 15V, resulting in a significant waste of electricity. Increasing the opening rate of the barrel can effectively reduce the groove voltage of the barrel plating. For parts with large volume of barrel plating, the holes should be drilled as large as possible; For small parts, the density of the holes can only be increased. The opening rate of the barrel is required to be above 30%, which can reduce the slot voltage and increase the current density, greatly saving electricity and increasing production. It is difficult to increase the opening rate to this height using manual punching, and this requirement can be achieved by using high-density polyethylene or polypropylene plastic molding boards.
