Overturn type top dust cover

Abstract

The invention relates to a flip-flop top dust hood, which comprises a hood body, wherein the hood body is arranged above a main iron tap channel of a casting house; the rear side of the hood body is pivoted on the edge of a blast tuyere platform; the front side of the hood body is provided with a suspension rope which pulls the hood body and can make the hood body overturned around a pivoted shaft on the rear side of the hood body; and the side face of the hood body is provided with an outlet which can be communicated with a dust removal pipeline. The flip-flop top dust hood sucks dust of an iron notch and the main iron tap channel and improves the stokehole environment, simultaneously can perform mechanized operation by utilization of a disassembly machine and a crane, greatly reduces the working strength of stokehole operators, and improves the working conditions of the operators, thereby having great significance in environmental protection of a blast furnace and improvement of theoperating level of the blast furnace.

Description

technical field [0001] The invention relates to a top dust removal hood used in the field of iron and steel metallurgy, in particular to a reversible top dust removal hood which not only facilitates the mechanized operation of a blast furnace, but also effectively absorbs smoke and dust emitted from a tap hole. Background technique [0002] In metallurgical production, the blast furnace plays a pivotal role as the main facility for smelting molten iron. However, when the blast furnace is tapping iron, it also produces a lot of smoke and dust, which has become one of the main sources of air pollution in iron and steel enterprises; moreover, with the strengthening of the smelting intensity of the blast furnace and the enlargement of the blast furnace, the amount of smoke emitted is increasing , causing more and more serious pollution. [0003] The total dust production of the casthouse is about 2.5kg / t iron, of which the dust generated at the taphole accounts for about 30%. T...

AI Technical Summary

Problems solved by technology

However, this structure is relatively complicated, and rails and rail brackets need to be added. The connection between the top dust removal hood and the dust removal pipeline is not easy to handle, and it is easy to leak air; It has a certain impact on the lifting of iron slag, and the dismantling machine cannot work under the track beam

[0008] This shows that above-mentioned existing iron hole top dust removal cover all exists certain deficiency, demands urgently further improving
