A trivalent zinc plating device

Abstract

The application relates to the technical field of trivalent color zinc hanging plating, in particular to a trivalent color zinc hanging plating device, which comprises a hanging plating pool, a waste heat recovery mechanism with a double-channel heat exchanger waste heat recovery function is arranged on the hanging plating pool, the waste heat recovery mechanism comprises a drainpipe one, a flange, an electromagnetic valve, a high-temperature pump and a drainpipe two, the water inlet end and the water outlet end of the high-temperature pump are respectively connected with the drainpipe one and the drainpipe two through the flange, one end of the drainpipe two extends to the inlet end of the double-channel heat exchanger, the hanging plating pool is provided with a foreign matter cleaning mechanism with a scraper impurity cleaning function, and the foreign matter cleaning mechanism comprises a multistage electric push rod and a support frame. The high-temperature pump is used for conveying water to the inlet end of the double-channel heat exchanger, the water flows along the waste liquid channel and releases heat, the low-pressure pump is used for conveying water from a water source to the other inlet end of the double-channel heat exchanger, the water flows along the water channel and absorbs heat, and therefore the waste heat recovery can be utilized.
