Description

Technical Field

[0001] The utility model relates to the technical field of copper recovery, in particular to a high-efficiency copper recovery resin tank for copper sulfate. Background Art

[0002] Acidic copper sulfate waste liquid is the copper sulfate waste liquid discharged from the electroplating tank during the copper manufacturing process of semiconductor wafers. Its main components are copper sulfate and sulfuric acid, of which the copper ion content is tens to hundreds of grams per liter, and the weight ratio of sulfuric acid is about 15%. In addition, it also contains a small amount of organic and inorganic additives. Acidic copper sulfate waste liquid belongs to Class HW22 hazardous waste. If it is not effectively treated, it will not only pollute the environment but also waste resources;

[0003] Publication No. "CN202011298190.1" is a novel resin copper removal process, which includes the following steps: Step 1: The reaction material is pumped into a cooler by a circulating pump and cooled and circulated with circulating water; Step 2: The pH value of the reaction material after cooling in step 1 is controlled at 2-3 and then transported from the bottom to the regeneration resin column; This process realizes the copper removal operation of the waste liquid by multiple flushing with ammonia water, water and sulfuric acid solution, so that the device can perform continuous online copper removal. This copper removal method has high copper removal efficiency and good copper removal quality. At the same time, through the automatic control of the copper removal process, the errors caused by manual control are effectively avoided, and the generation of by-products is avoided;

[0004] In the prior art, copper sulfate needs to pass through a water layer. The defect of this method is that when copper sulfate passes through the water layer, there will be residues, resulting in waste. The resin will swell after absorbing the copper component. The setting of the water layer can provide a space for the resin layer to expand. When collecting the copper precipitate, the copper precipitate needs to be manually taken out of the precipitation tank, which is very inconvenient. Therefore, we propose an efficient copper recovery resin tank for copper sulfate that can well solve the above problems. Utility Model Content

[0025] A drug injection port 2 is fixedly installed on the top of the resin tank shell 1, a feed port 5 is fixedly installed on the left side of the resin tank shell 1, a drain port 7 is fixedly installed on the right side of the resin tank shell 1, and a discharge port 6 is fixedly installed below the resin tank shell 1; through holes are opened at equal angles on the floating plate 3, and the floating plate 3 is viewed as a circle in top section;

[0026] The copper sulfate etching solution is injected through the feed port 5 provided on the left side of the resin tank shell 1, so that the copper sulfate etching solution is adsorbed by the resin body 4 placed in the resin tank shell 1, so as to absorb the copper ions in the copper sulfate etching solution. At this time, the resin body 4 will expand, so that the resin body 4 can drive the floating plate 3 to slide in the resin tank shell 1. By setting the floating plate 3, it is no longer necessary to add raw water into the resin tank shell 1, which is conducive to improving the copper recovery of copper sulfate;

[0027] When the resin body 4 fully absorbs the copper ions in the copper sulfate etching solution, the remaining waste liquid of the copper sulfate etching solution will be discharged through the drain port 7 provided on the right side of the resin tank shell 1, so as to facilitate the subsequent treatment of the resin body 4;

[0028] It also includes: support rods 8 are fixedly installed on the left and right sides of the resin tank shell 1, and an aggregate block 10 is arranged below the resin tank shell 1, and the left and right sides of the aggregate block 10 are fixedly connected to rotating rods 9, and both sets of rotating rods 9 are rotatably connected to the support rods 8; a limiting block 12 is fixedly installed on the right support rod 8, and a spring 13 is arranged in the limiting block 12, and a slide plate 14 is fixedly connected to the upper end of the spring 13, and the slide plate 14 is slidably installed in the limiting block 12; a gear 11 is fixedly connected to the end of the right rotating rod 9, and the lower end of the gear 11 is engaged and connected to a limiting frame 15; a limiting frame 15 is fixedly installed above the slide plate 14, and the limiting frame 15 is arranged in an "n"-shaped structure when viewed in cross section, and the upper end of the limiting frame 15 is arranged to penetrate the limiting block 12; the upper end of the aggregate block 10 is arranged to be open, and the aggregate block 10 forms a rotating structure with the support rod 8 through the rotating rod 9;

[0031] Sulfuric acid is injected through the injection port 2, and the resin body 4 is washed with sulfuric acid to perform continuous copper removal operations. The copper precipitate can be collected through the aggregate block 10. The limit frame 15 is pressed and the gear 11 is rotated.
