Energy conservation and environmental protection type smelting furnace

Abstract

The invention discloses an energy conservation and environmental protection type smelting furnace which comprises a supporting base and a furnace body. A filtering purification cavity is formed in themiddle end of an inner cavity of the supporting base, the left end of an inner cavity of the filtering purification cavity is divided by a third separating plate into acid-base neutralization cavities, a through hole is formed in the top end of the inner surface of the third separating plate, a sponge filtering layer, a polypropylene filtering net layer and a KDF filtering layer are fixedly connected to the positions, located on the right side of the third separating plate, of the inner cavity of the filtering purification cavity from left to right in sequence, grooves are formed in the periphery of the bottom of the supporting base, electric stretching rods are fixedly connected to the top ends of inner cavities of the grooves, and walking wheels are movably installed at the bottoms of the electric stretching rods. An inner cavity of the furnace body is divided by a first separating plate and a second separating plate into a first cavity, a smelting cavity and a second cavity; through the effects of a thermal conductive plate, a metal filtering net layer, a glass fiber coalescence filtering element, a circulating draught fan and a pipe, the need of people for circulated use of high temperature waste gas generated in the smelting process can be met, and the smelting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of melting furnaces, in particular to an energy-saving and environment-friendly melting furnace. Background technique [0002] Melting furnace refers to the equipment that melts metal ingots and some scrap metals and adds necessary alloy components, and smelts them into the required alloys through operations such as slag removal and refining. One: Classified according to heating energy, it can be divided into the following two types: ①. Fuel heating type (including natural gas, petroleum liquefied petroleum gas, coal gas, diesel oil, heavy oil, coke, etc.), which uses the reaction heat generated by fuel combustion to heat the charge; The alternating current generates an alternating magnetic field, and the furnace material in the magnetic field is heated by the induction current; 2. According to the heating method, it can be divided into the following two types: ①. Direct heating method: the heat generated wh...
