Problems solved by technology

[0007] Its two, the liquid electroplating nickel (A) that the first washing tank 12, the second washing tank 13, the third washing tank 14 and the fourth washing tank 15 are washed down layer by layer cannot be recycled, increasing material cost
[0008] Its three, although liquid electroplating nickel (A) is through multi-layer flushing, because the concentration of liquid electroplating nickel (A) after recovery tank 11 is used is constantly rising, and the simple small amount of circulation recovery mode is difficult to the liquid electroplating nickel (A) of a large amount of deposits. Therefore, liquid electroplating nickel (A) will often be brought to the washing tank in large quantities. If it is still not cleaned, it will affect the next stage of metal electroplating.

Abstract

The invention relates to an electroplating recovery method and an electroplating recovery device. The method comprises the following steps that: a recycling system is arranged between a soaking tank and a recovery tank for water-soluble electroplating metals and comprises a tank body, an evaporation heater, a water gauge and at least one pressure pump, wherein, the tank body applies the pressure pump to recover water-soluble electroplating molten metals at the bottom of the recovery tank; the water in the tank body is evaporated through the evaporation heater; and water-soluble electroplating molten metals with high concentration are recycled and sent back to the soaking tank. Therefore, the method can guarantee the high concentration of the soaking tank and the recovery efficiency of the recovery tank, can reduce the rinsing in the subsequent rinsing step, and not only reduces the pollution emission of a rinsing bowl but also avoids the electroplating molten metals from being brought into the metal electroplating operation in the next stage.

Description

technical field [0001] The present invention is an electroplating process recovery method and its equipment, in particular a method for the recovery of water-soluble electroplating metal, which can ensure the high concentration of the soaking tank and the recovery efficiency of the recovery tank, and can reduce the cleaning of the subsequent washing steps quantity. Background technique [0002] Electroplating is an important industrial technology, mainly to stably form a plated metal on the workpiece. After the voltage is input between the anode and the cathode, the metal ions in the electrolyte are attracted to swim to the cathode, and then plated on it after reduction. At the same time, the metal at the anode redissolves, providing more metal ions in the electrolyte. In some cases, insoluble anodes are used, and a new group of electrolytes needs to be added during electroplating to supplement the plating of metal ions. [0003] It generally refers to coating a film on a...
