Description

Technical Field

[0001] This utility model belongs to the technical field of steel wire pickling equipment, and specifically relates to a steel wire pickling equipment. Background Technology

[0002] The pickling speed of metal materials is directly proportional to the concentration of reactants and inversely proportional to the concentration of products. Generally, the higher the concentration of hydrochloric acid or dilute sulfuric acid, the faster the pickling speed. As the amount of metal material being cleaned increases, the concentration of hydrochloric acid or dilute sulfuric acid gradually decreases. When the concentration of hydrochloric acid or dilute sulfuric acid can no longer meet the requirements for cleaning rate and effect, it needs to be disposed of. According to the National Hazardous Waste List, waste acid after metal pickling is classified as hazardous waste and must be disposed of by a qualified hazardous waste treatment unit. To reduce disposal costs, units using hydrochloric acid and dilute sulfuric acid to clean metal materials must minimize the concentration of waste acid while ensuring the cleaning effect.

[0003] A search revealed that Chinese patent CN114411159A discloses a pickling device and method for metal materials, including a first acid tank, a second acid tank, a third acid tank, a water washing tank, a waste acid tank, and a track frame. The first acid tank contains raw acid solution, the second acid tank contains secondary acid solution, and the inner wall of the third acid tank contains waste acid solution. The first acid tank has a first acid inlet and a first acid outlet on one side, and the second acid tank has a second acid inlet on the outer side of one end. The second acid tank has a second acid outlet on the outer side of the other end, the third acid tank has a third acid inlet on the outer side of one end, and a third acid outlet on the outer side of the other end. The third acid outlet is connected to the waste acid tank through a pipe. Currently, steel wire roll pickling is mainly carried out by sending the steel wire roll into the pickling tank through a hoist. However, traditional pickling tanks have a simple function and structure, and are generally constructed by directly building a whole with cement. On-site construction is time-consuming and labor-intensive. Furthermore, if the plant needs to make adjustments to the equipment structure, the pickling tank can only be scrapped.

A connecting chain 122 is fixedly installed on the outside of the rotating base 121. The other end of the connecting chain 122 is provided with a fixing seat 123, which is welded to the outside of the pickling tank 1. The rotating base 121 on the hand-tightening bolt 905 is connected by the connecting chain 122 and the fixing block 10 through the fixing block 10. This makes it convenient to use the hand-tightening bolt 905 while preventing the hand-tightening bolt 905 from being lost during transportation.

[0023] Operating principle and advantages: During installation, when connecting multiple pickling tanks 1, after positioning and inserting one pickling tank 1 and another pickling tank 1, the corresponding connecting block 903 is inserted into the corresponding connecting groove 906.
