Abstract
PURPOSE:To automate the operation for recovering dross so as to improve the working environment, by recovering metallic zinc through the reaction of the dross with the flux in an inert atmosphere, and by washing out the formed ash and Cl2 with alkali soln. CONSTITUTION:Top dross (b) which floats on a zinc plating bath (a) is fed to a charging inlet 29 of a recovering unit 21, while flux (c), e.g., ZnCl2 etc., is charged through an inlet by opening the cover 32, which is then closed. The dross (b) and flux (c) put into the recovering unit 21 is transferred into the body 23, into which is introduced 34 inert gas, by the rotation of a screw 24, where zinc (d) formed by the reaction of both materials is recovered 38. The ash (e), which is formed by the reaction of ZnO contained in the dross (b) with the flux (c) and is floating on the zinc bath, is collected together with the unreacted dross to the front of a separation plate 38, and only the ash (e), which is lighter than the dross, is sent to an ash-discharging cylinder 40 over the separation plate 38. The separated inert gas is delivered through the cylinder 40, a vertical flue cylinder 42, a horizontal flue cylinder 43 to a washing tower 50, where it is washed with the spray of alkali soln. in order to remove Cl2 gas and residual finely powdered ash.
