An energy-saving and environment-friendly smelting device for pilot overflow non-ferrous metal recovery

Abstract

The invention discloses an energy-saving and environment-friendly smelting device for recovery of pilot overflow non-ferrous metals, which comprises a furnace body, a top cover connected to the furnace body through screw threads, and a crucible bottom movably connected to the inner wall of the furnace through buckles. The bottom of the furnace body is provided with a water cooling device, the water cooling device includes a water outlet pipe, a water inlet pipe and a furnace bottom cooling pipe, the furnace bottom cooling pipe is arranged at the bottom of the crucible bottom, and the inner wall of the furnace body is a hollow structure, so One end of the water inlet pipe is connected with a furnace bottom cooling pipe, and the furnace bottom cooling pipe is connected through the water outlet pipe. The water inlet pipe is correspondingly connected with a wall pipe, and the wall pipe is inserted into the inner wall of the furnace body. The bottom of the inner wall is connected to the water outlet pipe, the bottom of the furnace body is provided with a cavity, and the top of the cavity is connected with a wall pipe, and the water inlet pipe is connected to the cavity. The present invention has good pollutant removal effect And the characteristics of energy saving and emission reduction.

Description

technical field [0001] The invention relates to the technical field of metal smelting, in particular to an energy-saving and environment-friendly smelting device for recovery of pilot overflow non-ferrous metals. Background technique [0002] In the process of mechanical manufacturing, it is necessary to smelt the corresponding parts. The cast iron block is melted into molten iron and then poured into the sand mold to be cooled and then unpacked to obtain the casting. [0003] The working temperature in the existing smelting furnace is as high as more than 1,000 degrees, and a large amount of waste heat causes a serious waste of heat. The waste heat leaving the heat storage and exhaust smoke accounts for the highest proportion. The high-temperature flue gas takes away a lot of heat energy and wastes a lot of energy; the existing The desulfurization and dust removal in the melting furnace needs to be carried out in the same equipment at the same time, which requires high stab...

[0003] The working temperature in the existing smelting furnace is as high as more than 1,000 degrees, and a large amount of waste heat causes a serious waste of heat. The waste heat leaving the heat storage and exhaust smoke accounts for the highest proportion. The high-temperature flue gas takes away a lot of heat energy and wastes a lot of energy; the existing The desulfurization and dust removal in the melting furnace needs to be carried out in the same equipment at the same time, which requires high stability of the desulfurization and dust removal system, and the actual application effect is poor
