Embodiment Construction

[0014] like figure 1 shown, figure 1 It is a schematic structural diagram of a metal smelting electric furnace with a dust removal device proposed by the present invention.

[0015] refer to figure 1 , a metal smelting electric furnace with a dust removal device proposed by the present invention includes: an outer furnace shell 1, an inner furnace 2, and a cover body 3;

[0016] The outer furnace shell 1 is provided with a accommodating chamber with a top opening, and the cover body 3 is located at the top opening of the accommodating chamber. The accommodating chamber includes a heating chamber and an exhaust chamber that communicate with each other, and the heating chamber is located in the Above the exhaust chamber, the inner wall of the heating chamber is provided with an electric heating tube 8, the side wall of the exhaust chamber is provided with an exhaust port and the bottom is provided with a slag discharge port, and the side wall of the exhaust chamber is provided...

Abstract

The invention discloses a metal smelting electric furnace with a dust collector. A cover body is located at a top opening of an outer furnace shell. A heating cavity and an exhaust cavity located below the heating cavity are formed in the outer furnace shell. An annular support plate is arranged on the side wall of the exhaust cavity and is located above an exhaust opening. A plurality of supportblocks used for supporting an inner furnace lining arranged at intervals are arranged at the top of the annular support plate. The inner furnace lining is supported in the heating cavity through the multiple support blocks. A downwards-extending annular baffle is arranged at the inner edge of the annular support plate. Through the optimally designed metal smelting electric furnace with the dust collector, the structure design is optimal and reasonable, gas is discharged at the bottom of the outer furnace shell, the inside heat utilization efficiency of the outer furnace shell is ensured effectively, meanwhile, the exhaust cavity provides a buffer area for the gas, tail gas stays at the bottom of the outer furnace shell before discharged, thus dust in the gas drops, then the gas is discharged, and dust contained in the discharged gas is reduced effectively while the heat utilization efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of metal smelting furnaces, in particular to a metal smelting electric furnace with a dust removal device. Background technique [0002] The metal smelting furnace is a kind of thermal furnace, which can complete the melting and tempering of metal materials and other auxiliary materials into the heating furnace. Thermal furnaces for pyrometallurgical processes that produce crude metals or metal enrichments and slag. Whether the furnace body structure of the metal smelting furnace is reasonable has an important influence on the metal smelting furnace. [0003] In the process of metal smelting, high-temperature exhaust gas will be generated, and the exhaust gas contains a large amount of dust, which will cause damage to the environment. SUMMARY OF THE INVENTION [0004] In order to solve the technical problems existing in the background technology, the present invention proposes a metal smelting electric f...
