Upper vibrating plate type continuous ultrasonic cleaning unit for steel wire

The utility model relates to an upper vibrating plate type continuous ultrasonic cleaning unit for a steel wire. The unit comprises a strip-shaped cleaning tank, wherein an incoming wire separation carrier roller and an incoming wire pressing roller are mounted at an incoming wire end of the cleaning tank; an outgoing wire separation carrier roller and an outgoing wire pressing roller are mounted at an outgoing wire end of the cleaning tank; a wiping device is arranged between the outgoing wire pressing roller and the outgoing wire separation carrier roller; the incoming wire pressing roller and the outgoing wire pressing roller are used for pressing the steel wire into a cleaning solution; the unit is characterized in that: multiple ultrasonic vibrating plates distributed at equal intervals are arranged between the incoming wire pressing roller and the outgoing wire pressing roller; the ultrasonic vibrating plates are mounted on the lower surface of a cover plate; and a transmitting surface of the ultrasonic vibrating plate is immersed in the cleaning solution for certain depth and is certain distance away from the steel wire. According to the utility model, an ultrasonic cleaning method is adopted to remove the iron oxide layer away from the surface of the steel wire, the cleaning solution is weak phosphate solution, recycling of the weak phosphate solution is realized, and environmental pollution is almost eliminated; and the surface of the steel wire can be completely cleaned so that the steel wire becomes cleaner.
