在大型铜管材生产时,表面易产生和附着金属杂质和氧化物,为保证其质量,需进行酸洗。在酸洗时,机械抓手将每一根铜管分开,并自动的掉入酸洗槽、漂洗槽中进行酸洗和漂洗。酸洗槽底部有自动回水装置,它能剥离铜管表面的氧化皮和杂质。酸洗时产生的酸雾由吸风管道送到吸收塔中。酸洗时所用的酸液采用自动配酸系统进行配置,将浓硫酸和浓硝酸在配液设备中配成一定浓度的稀酸,再由泵自动的抽到酸洗槽中。酸洗时,烯酸和水按一定的速度补充到酸洗、漂洗槽中,溢出的液体会通过溢流口流出。酸洗到一段时间,废水口排空所有的水,出水口对底部沉淀进行冲洗和回收。
In the production of large-scale brass, the surface is easy to produce and attach metal impurities and oxides, in order to ensure its quality, need to be pickling. During pickling, the mechanical grip separates each copper tube and automatically falls into a pickling tank where it is pickled and rinsed. Pickling tank bottom automatic backwater device, which can strip the surface of the oxide scale and impurities. The acid mist generated during pickling is sent to the absorption tower by suction pipe. Pickling the acid used in the automatic acid system configuration, the concentrated sulfuric acid and concentrated nitric acid in the dosing equipment dubbed a certain concentration of dilute acid, and then automatically by pumping to the pickling tank. Acid pickling, acid and water at a certain speed added to the pickling, rinsing tank, the overflow of liquid overflow through the mouth out. Pickling for a period of time, the waste outlet emptying all the water, the outlet of the bottom of the precipitate washing and recycling.
