Waste lead-acid storage battery smelting device and method

Abstract

The invention discloses a waste lead-acid storage battery smelting device and method. The waste lead-acid storage battery smelting device comprises a smelting device body and a first spiral feeder, wherein the first spiral feeder is installed in the lower end of the smelting device body, and a material channel is formed on the lower side of the first spiral feeder. A molten lead outlet is formed in the outer wall of the right side of the lower end of the smelting device body, and mixed fuel inlets are formed in the outer wall of the front side of the lower end of the smelting device body. A second filter screen is arranged in the inner wall of the lower end of the smelting device body. The first spiral feeder and a second spiral feeder are internally arranged, when the first spiral feederand the second spiral feeder conduct feeding, materials sequentially pass through a fine smelting cavity, a heat preservation cavity and a rough smelting cavity, and then layered smelting of the materials is achieved; and besides, the materials are heated and roasted in the feeding process through waste heat of molten lead, in this way, the heat utilization rate of the waste lead-acid storage battery smelting device in the smelting process is increased, the production cost is lowered, and the production efficiency is improved at the same time.

Description

technical field [0001] The invention belongs to the technical field related to battery smelting, and in particular relates to a waste lead-acid battery smelting device and a smelting method. Background technique [0002] Waste lead-acid batteries can be treated with pollution-free lead-acid battery technology for vehicles, and the combination of hydrometallurgy and pyrometallurgy can process sulfuric acid in lead-acid batteries into washing powder raw materials. In the process of use, the lead metal and the paste in the battery can be melted in a rotating furnace and converted into powder, and the polyethylene grid and polypropylene shell of the lead battery shell are processed into granules, which can be used again. No secondary pollution will be caused during the whole production process. [0003] The existing waste lead-acid battery smelting device technology has the following problems: [0004] 1. The traditional waste lead-acid battery smelting device is transported t...
