Lead smelting refining device with lead discharged from pot bottom

Abstract

The utility model discloses a lead smelting refining device with lead discharged from a pot bottom, and belongs to the field of non-ferrous metal smelting mechanical equipment. The refining device comprises a furnace body, a lead discharging valve, a lead discharging pipe, a refining pot, a stirring machine, a feeding port, a smoke outlet and a pot cover. The refining pot is arranged on the furnace body, and the bottom of the refining pot is connected with the lead discharging valve through the lead discharging pipe. The pot cover is connected to an opening in the upper end of the refining pot and seals the opening of the refining pot. The feeding port and the smoke outlet are formed in the pot cover, and the stirring machine is connected to the upper end of the pot cover. The lead smelting refining device with the lead discharged from the pot bottom has the advantages that 1, the investment is low, and use is convenient; 2, the flow velocity of lead liquid is stable, and the flow is controllable; 3, the lead is discharged from the pot bottom, oxide scum on the surface of the lead liquid can be prevented from entering a casting mold, alloy elements are less in burning loss and are uniformly distributed without segregation, and the product quality is ensured; and 4, the pot cover is hermetically connected with a pot seam allowance, the production process is completed in a closed state, generated waste gas can be discharged through the smoke outlet on the lead pot cover and enters a dust removal facility to be purified, so that the pollution is reduced, and the working environment is improved.

Description

technical field [0001] The invention belongs to the field of nonferrous metal smelting machinery and equipment, and in particular relates to a lead melting and refining device for placing lead at the bottom of a pot. Background technique [0002] The crude lead produced by reduction and smelting of lead-containing materials such as lead ore or waste lead-acid batteries contains impurities such as antimony, tin, arsenic, iron, cadmium, copper, silver, bismuth, etc., and the purity can only meet the user's requirements after refining and removing impurities. There are two types of crude lead refining: fire refining and wet refining. Fire refining has high production efficiency, fast lead turnover, and simple equipment, but the production process is long; wet refining process is short, lead recovery rate is high, but the turnover is slow and capital is occupied Large, the equipment covers a large area; therefore, domestic and foreign lead smelters widely use fire refining. The ...
