Vertical Lead Refining Furnace For Waste Lead Acid Battery Recycling Smelting

Large capacity and compact overall layout This vertical lead refining furnace adopts vertical cylindrical overall structure. The main furnace body is rolled and welded by heavy thick steel plates. Internal space can hold large volume molten lead liquid. The whole equipment occupies limited workshop floor space. It can be well adapted to newly built recycling plants and old production line reconstruction projects. Different tonnage specifications can be customized according to customer real production demands.

Stable temperature control and reliable melting performance The furnace matches segmented heating system. Operators can adjust internal working temperature within reasonable range. The inner lining uses high temperature resistant refractory materials. It can keep stable working state under long time high temperature operating conditions. The equipment can complete raw material melting, metal liquid heat preservation and impurity separation work continuously. It effectively reduces metal oxidation loss during smelting process and improves final metal recovery rate.

Flexible raw material compatibility The furnace can process multiple types of raw materials from waste lead acid battery recycling industry. It can handle waste lead grids, pretreated lead paste, lead alloy scraps and other secondary lead raw materials. Users can add corresponding flux inside the furnace to complete impurity removal work. It can realize crude lead refining, lead alloy blending and other diversified production tasks to meet varied production objectives.

Reasonable structural design and convenient daily operation Humanized structural layout reserves sufficient operation space for feeding, slag removal and molten lead discharging. Each operation step follows simple workflow. Workers can finish daily production work without complex training. The furnace body sets reliable sealing structure, which can effectively restrain dust and flue gas overflow in working environment. Cooperated with supporting flue gas treatment system, it can satisfy local environmental protection supervision standards.

Robust construction and easy maintenance Key load bearing parts adopt high strength carbon steel material. Main furnace shell has strong anti deformation capacity under high temperature working environment. Vulnerable components are designed for quick disassembly and replacement. Daily inspection and component replacement do not need long time equipment shutdown. It lowers production interruption risk and guarantees continuous operation of the whole smelting production line.

Working Principle

Raw materials such as waste lead grids and lead paste are sent into inner cavity of vertical lead refining furnace. The heating system provides heat energy to raise internal temperature. Raw materials gradually melt and turn into molten lead liquid. Impurities with different density will separate from molten lead under high temperature environment. Part impurities float on liquid surface and form slag for manual or mechanical slag removal. The segmented temperature control system maintains stable temperature of molten lead inside furnace. After finishing impurity removal and alloy blending procedures, qualified molten lead can be discharged from outlet. The output molten lead can flow into subsequent lead casting equipment to produce standard lead ingot products. The whole working flow can cooperate with feeding device, flue gas dust removal equipment and casting machine to form complete secondary lead recycling production unit.

Main Technical Parameters

Core Functions

Secondary lead raw material high efficiency melting Realize large batch melting for multiple secondary lead raw materials. Convert solid waste lead materials into qualified molten lead liquid, provide raw material foundation for subsequent refining and casting processes. The furnace can keep stable melting efficiency under long time continuous running, match the production rhythm of supporting upstream and downstream equipment.

Molten lead heat preservation and alloy homogenization After raw material melting is completed, the furnace maintains constant internal temperature. It avoids molten lead solidification inside cavity. Workers can add different alloy raw materials inside furnace. Through stirring operation, achieve even mixing of molten lead components, support small batch and multi specification lead alloy production requirements.

Impurity separation and slag removal assistance With the help of flux and high temperature environment, separate iron, aluminum and other miscellaneous impurities from crude lead. Impurities form floating slag layer on liquid surface. Operators can complete slag removal work conveniently. Reduce impurity content inside molten lead and improve quality of final lead ingot finished goods.

Coordinate complete recycling production line operation This furnace acts as core smelting host of waste lead acid battery recycling line. It can dock vibrating feeder, rotary furnace, lead ingot casting machine and dust removal equipment. Complete continuous production flow from raw material input to finished lead ingot output. It supports whole plant automatic and semi automatic production modes.
