AI Technical Summary
Technical Problem
Hot zinc scum oxidizes and produces flue gas in the ashes stir-frying machine, resulting in environmental hazards and zinc metal burning and damage, reducing recycling rate.
Method used
A cold ash bucket is designed to use the principle of screw conveying and cooling water heat exchange to quickly cool the high-calorie zinc scum, reducing the oxidation of metal zinc and flue gas production.
Benefits of technology
The rapid reduction of zinc scum from 450℃ to 35℃-100℃ is achieved, reducing the oxidation of metal zinc and flue gas generation, improving the recovery rate of zinc metal and achieving environmental protection purposes.

Abstract
The present application discloses a cold ash barrel for rapid cooling of hot zinc slag. High-calorie zinc slag can directly enter the interior of the device through a connector from a slag discharge port of an ash roasting machine. A motor and a gearbox are combined to drive a screw to rotate, and the zinc slag entering the cylinder body is transported from an input end to an output end at a certain speed. At the same time, a water pump and a cooling device also work synchronously together to transport cooling water in a water tank through a water inlet pipe to an interlayer outside the cylinder body, and allow the cooling water to flow through the outside of the cylinder body along a serpentine channel in the interlayer, thereby exchanging most of the heat of the cylinder body and the zinc slag, and being discharged from a water outlet pipe, entering a cooling device to cool the zinc slag for cooling treatment by a cooling mechanism, and returning to the water tank after the treatment is completed for reuse. The zinc slag can be directly and rapidly reduced from 450°C to about 35°C-100°C, thereby directly reducing the oxidation of metallic zinc in the zinc slag, reducing the generation of smoke, and the burning loss of metal, so as to achieve the purpose of environmental protection and improving the recovery rate of zinc metal.
