Problems solved by technology
But in actual use, since most of the cathode rods are directly arranged in the plating tank, the effect of preventing the precipitation of metallic nickel is not ideal, and at the same time it occupies the space in the tank
At the same time, in the electroless plating process, the solution needs to be stirred and circulated. In the industry, stainless steel filter pumps are generally placed outside the tank for circulation. The welding pipeline system is more complicated. At the same time, the tank needs heat preservation and cooling systems, so the pipeline and tank leak. very high chance

Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings.
[0018] Figure 1 and figure 2 As shown, a novel stainless steel electroless nickel plating tank of the present invention includes a stainless steel tank body 1, a cathode mechanism 2, a spray pipe 3, a stainless steel bag filter 4, an exhaust pipe 7, and a filter outlet 9. Such as image 3 As shown, the stainless steel tank body 1 includes a tank body air duct 10, a cooling water inlet pipe 11, a cold water layer shell 12, an inner tank 13, a liquid discharge port 14, and a cooling water outlet 15; the bottom plate of the inner tank 13 adopts an integral Type bending structure reduces the welds in the tank, improves the smoothness of the surface of the inner tank 13, minimizes the intensification points in the tank, and reduces nickel deposition. One end of the bottom of the inner tank 13 forms a large arc structure, which is convenient for liquid circulation. The c...

The invention relates to the technical field of electroplating equipment, and particularly relates to a novel stainless steel chemical nickel plating tank applied to a chemical nickel plating technology in the electroplating industry. Integral design is adopted, namely that a filtering circulation system is moved into a tank, so that a pipeline system is simplified. By adopting great-circle integral design in a tank body, weld joints are reduced, the surface of the inner wall of the tank body is smoother, and activation points in the tank are reduced so as to reduce metal deposition. With new anode protection design, a cathode is moved from inside to outside of the tank and mounted by a special U-shaped cathode mounting tube; the cathode mounting tube is hidden in a cold water layer, thus the inner tank is cleaner, and the anode protection effect is better. A special cold water layer is designed outside the inner tank and is used for adjusting the temperature of the chemical nickel plating solution. The design of a heat preservation layer outside the cold water layer is canceled; when the tank body needs heat preservation, the water in the cold water layer is drained, and the air is used for thermal insulation and heat preservation, so that the structure of the tank body is simplified.
Description
technical field [0001] The invention relates to the technical field of electroplating equipment, in particular to a novel stainless steel electroless nickel plating tank applied to the electroless nickel plating process in the electroplating industry. Background technique [0002] Electroless nickel plating is widely used in the electroplating industry. The electroless nickel plating technology is mature, stable in performance, diverse in function and wide in use. Electroless plating can be applied not only on metal surfaces, but also on non-metal surfaces through special activation and sensitization treatments. Electroless plating has the characteristics of simple equipment, high coating hardness, good wear resistance and strong corrosion resistance. Therefore, the coating quality is better than that of electroplating. The electroless nickel plating solution is highly corrosive, and the working temperature is required to be above 90°C. Therefore, there are special require...
