The invention discloses a
zinc plating
scrap steel
recovery device which comprises a hoisting device, stirring devices, a first container, a second container, a third container, a fourth container and a fifth container, and the stirring devices are arranged in the first container, the second container, the third container, the fourth container and the fifth container. A hoisting device is used for carrying and moving the galvanized
scrap steel among a first container, a second container, a third container, a fourth container and a fifth container, and the hoisting device comprises a
gantry crane, a lifting frame, a lifting lug and a moving mechanism. According to the method, the
zinc coating on the surface of the steel is effectively stripped through the reaction of
hydrochloric acid and the
zinc coating, the zinc
elution speed is higher than that of an
ammonia complexing method, the production cost is reduced, and the production benefit is improved; as the
hydrochloric acid concentration is low, compared with a high-concentration
hydrochloric acid leaching method, the technology has the advantages that the hydrochloric acid
utilization rate is high, volatilization is little,
pollution is small,
corrosion to an iron base is small, separated steel and a zinc
coating can be better treated separately, and the
resource utilization rate is increased.
