Problems solved by technology

[0004] However, this pickling method has the following problems: (1) A large amount of acid mist is generated during the pickling process, which is difficult to collect and recycle. The acid mist will cause corrosion and damage to the plant and equipment, pollute the environment, and endanger human health at the same time (2) the pickling efficiency is low, the pickling quality is poor, and the

specific Embodiment approach

[0067] According to a specific embodiment of the present invention, the pickling tank 101 includes: a tank body 105; a tank body cover 106, which is sealedly mounted on the tank body 105; a fixing bracket 107, which is fixedly installed on the tank body 107 In the body 105, and the fixing bracket 107 is provided with a plurality of stations arranged along the length direction, and the parts to be pickled can be pickled in sequence at the plurality of stations. The tank cover 106 is used to seal the pickling tank 101 to prevent the acid mist generated during the pickling process from escaping and polluting the environment. The lifting seat 311 can be arranged on the tank cover 106 . A plurality of said stations can divide the parts to be pickled into groups so that they can be processed in batches. In addition, a sliding groove 108 may be provided on the groove cover 106, so that the lever link 401 can be accommodated to slide therein.

Abstract

The invention relates to the plating field and discloses a pickling system and a pickling method. The pickling system comprises a pickling bath group (1) which comprises a plurality of pickling baths (101) that are arranged between a feeding end and a discharging end in the length direction of the pickling system, and parts to be pickled can be sequentially pickled in the pickling baths (101). Through step-by-step pickling of the parts to be pickled in the pickling baths, not only can the pickling quality be improved and the parts to be pickled be prevented from mis-plating, but also a pickling agent in one of the pickling baths can be transferred to the upper stage step by step, a pickling solution, of which the concentration is reduced and impurities are increased, in the first-stage pickling bath can be discharged and disposed, the dilution speed of the pickling agent in the multiple stages of the pickling baths is reduced, accordingly, the utilization ratio of the pickling agent is improved, and the production cost is lowered.

Description

technical field [0001] The invention relates to the field of plating, in particular to a pickling system and a pickling method. Background technique [0002] Hot-dip galvanizing is an effective method of metal anti-corrosion, which plays an important role in reducing corrosion and prolonging life of metal parts, as well as saving energy and materials. Generally, the process steps of hot-dip galvanizing of metal parts include: feeding—pickling, rinsing, galvanizing—drying—hot-dip galvanizing—internal and external blowing—cooling—passivation—inspection. Among them, pickling is a key link in the production process of hot-dip galvanizing, and the quality of pickling directly affects the quality of hot-dip galvanizing products. At present, the pickling process in the hot-dip galvanizing industry adopts the pickling-rinsing-assisting method, and the pickling material used is hydrochloric acid. The specific steps are: pickling, soaking the metal parts in the pickling tank to remov...
