Description

Technical Field

[0001] The utility model relates to the technical field of lead-zinc recovery equipment, and particularly relates to a metal lead-zinc recovery device. Background Technique

[0002] During the production process of the zinc system, a large amount of lead-zinc refractory materials are produced, occupying a large amount of raw material land of the company and causing difficulties in storage and stacking management. The reduction furnace is used to process the refractory materials inside the company and purchased from outside, such as high-leaching slag, sediment vanadium slag, and high-rich refractory ore. At the same time, it is necessary to ensure the increase in the output of the fuming furnace. The reduction furnace conducts exploratory experiments, formulates plans, and adjusts the material ratio, so as to realize the conversion of hazardous waste resources into general solid waste resources and the consumption of various refractory materials, and finally achieve a balance in the resource utilization and availability of zinc slag and lead-containing hazardous waste.

[0003] The existing Chinese utility model patent with the reference publication number of CN109014426A discloses a metal lead-zinc recovery device, which includes a support mechanism, a lubrication mechanism, a first cutting mechanism, a second cutting mechanism, and a protection plate; on the basis of the traditional horizontal cutting method, the present invention adds a second cutting mechanism for vertical cutting. The first driving mechanism can drive the second cutting blade to rotate, and the second driving mechanism drives the second cutting blade to move horizontally as a whole, so as to divide the recovered plate into several square small pieces, making the contact surface for reaction extraction larger and the efficiency higher; the plate can be pressed tightly by the pressing plate to prevent the plate from bouncing during cutting, making the cutting more stable. The setting of the protection plate can further improve the protection performance; the lubrication mechanism can apply lubricating oil to the surface of the plate, making the cutting smoother and reducing the wear amount of the blade.

[0004] Based on the retrieval of the above patent and the combination of the equipment in the existing technology, it is found that the reduction furnace converts hazardous waste resources into general solid waste resources and consumes various refractory materials, and finally achieves a balance in the resource utilization and availability of zinc slag and lead-containing hazardous waste. The traditional reduction furnace uses iron ore to smelt lead, resulting in difficult treatment of the subsequent jarosite slag and the inability to recover the metal later, reducing the metal recovery rate. The existence of these problems affects the use of the device. Content of the Utility Model
