Description

Technical Field

[0001] The utility model relates to the technical field of industrial waste liquid treatment, in particular to an ammonium chloride mother liquor pool. Background Technique

[0002] In the machinery manufacturing industry, since the printed circuit boards of its electronic components and electronic devices need to be electroplated with copper, a large amount of copper-containing waste liquid, especially copper sulfate waste liquid, will be generated during the production of printed circuit boards. If not recycled, the copper ions in the waste liquid will be wasted in vain. At present, for the treatment of copper-containing waste liquids such as copper sulfate, ammonium chloride solution is usually used to carry out a complexation reaction on the copper ions in the copper-containing waste liquid to generate copper ammonia complex ions, so as to recycle the copper in the waste liquid;

[0003] The authorized patent publication number CN208482273U discloses an ammonium chloride mother liquor pool. The main pool body of this device is provided with a dissolution net for placing solid ammonium chloride for dissolution at the upper part. After the dissolution is completed, the excess solid ammonium chloride can be taken away by lifting the dissolution net out of the liquid surface, so that ammonium chloride can be effectively utilized; in addition, since a heat insulation material layer is provided on the outer side of the pool body, and stirring devices are provided on both sides of the pool body, the ammonium chloride mother liquor pool has the advantage of fast dissolution rate of ammonium chloride; however, when the mother liquor pool is carrying out chlorination work, there are still the following defects:

However, during the liquid guiding and liquid taking operations of the solid ammonium chloride, it will be affected by the stirring structure and cannot take liquid stably, reducing the liquid taking accuracy of the structure rising out of the liquid surface. At the same time, when stirring the solid ammonium chloride, generally an excessive amount of ammonium chloride is directly put into the pool, resulting in the inability to stir the excessive ammonium chloride evenly, reducing the dissolution efficiency of ammonium chloride and reducing the utilization effect of the ammonium chloride mother liquor.
