Description

Technical Field

[0001] The utility model relates to the technical field of nickel plating pools, in particular to a constant temperature device for a chemical nickel plating pool. Background Art

[0002] Electroplating technology is widely used in the manufacturing industry because it can prevent corrosion, improve wear resistance, conductivity, reflectivity and enhance aesthetics. In production, the best process temperature for nickel plating is 50-55°C. Only when the temperature is maintained at 50-55°C can the brightness, density and bonding strength of the obtained coating reach the best. A lower temperature will have an adverse effect on the coating.

[0003] At present, in the prior art, the temperature of the nickel plating pool is usually measured by a handheld thermometer. When the temperature reaches the required temperature, the power is manually cut off. This method not only increases the labor intensity of the manual labor, but also fails to measure the temperature of different layers of the solution, resulting in low accuracy of temperature measurement. In addition, the solutions of different layers inside are not mixed, resulting in temperature differences between the solutions of different layers in the nickel plating pool, which may reduce the quality of nickel plating. For this reason, we propose a constant temperature device for a chemical nickel plating pool. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a constant temperature device for a chemical nickel plating pool. The controller controls the operation of the meandering heating tube, and the meandering heating tube works to uniformly heat the nickel plating pool body. Then the controller controls the operation of the water pump, and the water pump works to suck the solution of the lower layer into the water inlet pipe, the working pipe and the connecting pipe, so that under the action of the nozzle, the solution of the lower layer can be sprayed to the upper layer, thereby effectively improving the uniformity of the temperature of the upper and lower layer solutions. Among them, the first thermocouple sensor can detect the temperature of the upper layer solution, and the second thermocouple sensor can detect the temperature of the lower layer solution. The first thermocouple sensor and the second thermocouple sensor send temperature signals to the control panel. When the average value of the first thermocouple sensor and the second thermocouple sensor reaches the temperature required by the nickel plating pool body, the controller controls the meandering heating tube to stop working. Under the action of the water pump, the temperature of the upper and lower layers of the solution is effectively guaranteed to be constant. The nickel-plated parts are conveniently sent into or out of the nickel plating pool body through the support assembly, which can not only reduce the labor intensity of manual labor, but also effectively improve the quality of nickel plating, and can effectively solve the problems in the background technology.
