Energy-saving environment-friendly type smelting furnace

Abstract

The invention discloses an energy-saving environment-friendly type smelting furnace, belonging to the field of lead recycling equipment. The smelting furnace comprises a heat supply smelting system, a feeding system, a discharging system, and a waste gas and smoke dust collecting system, wherein the heat supply smelting system comprises a bracket, a smelting chamber, a heating device and a lead smelting pot; the feeding system is formed by a feeding cabin rail and a feeding cabin which is slidingly arranged on the feeding cabin rail; the discharging system is arranged below a discharging opening of the smelting chamber of the heat supply smelting system and corresponds to the discharging opening; the waste gas and smoke dust collecting system comprises an upper dust removing chamber and a lower dust removing chamber; the upper dust removing chamber is arranged above the smelting chamber of the heat supply smelting system and is communicated with the feeding system; the upper dust removing chamber is communicated with a waste gas collecting pipeline through a pipeline; the lower dust removing chamber is arranged below the smelting chamber of the heat supply smelting system and is communicated with the discharging system; and the lower dust removing chamber is communicated with the waste gas collecting pipeline through a pipeline. The smelting furnace has the advantages of simple structure, energy saving and good environment-friendly performance.

Description

technical field [0001] The invention relates to the field of lead smelting equipment, in particular to an energy-saving and environment-friendly melting furnace for melting lead paste, lead mud, waste lead grids and lead parts in the waste lead-acid battery recycling industry. Background technique [0002] At present, there are 186 renewable lead enterprises in my country that can be counted, with a large number, small scale, extremely simple equipment, high energy consumption and serious pollution emissions. In 2011, 80% of them were shut down by the environmental storm. Statistical data show that my country's renewable lead output was 135 tons in 2010, and reached 1.4 million tons in 2011, accounting for about one-third of the total output of metallic lead. The recovery rate of lead-acid batteries is as high as 96.5%, ranking first among recycled items. Secondary lead production in the United States accounts for 58% of total lead production, 64% in Japan, 62% in Germany,...
