Description
technical field [0001] The invention relates to the technical field of steel pipe processing, in particular to the technical field of a steel pipe pickling device for recycling pickling liquid. Background technique [0002] Pickling is a common step in the surface treatment of steel pipes. During pickling, the steel pipes are all stacked together, so that the steel pipes that are in contact with each other cannot be pickled by the pickling solution, thereby affecting the pickling effect of the steel pipes. [0003] In addition, a lot of acid mist will be generated in the pickling process, resulting in a poor working environment and affecting the health of the staff. [0004] Domestic steel pipe pickling workshops basically use tank pickling, and there are a lot of iron scale and iron filings in the pickling solution. When the iron ion concentration in the pickling tank reaches a certain peak value, the acid solution in the tank is discharged together with iron scale and iro...
