Device for removing residual materials at lower part of large blast furnace hearth

Abstract

The invention discloses a device for removing residual materials at the lower part of a large blast furnace hearth, and relates to the technical field of blast furnace hearths. The device for removingresidual materials at the lower part of the large blast furnace hearth includes a lower movable transmission mechanism and a horizontal transmission mechanism, and the lower movable transmission mechanism is provided with a conveying device steel bracket. By means of the device for removing residual materials at the lower part of the large blast furnace hearth, mechanized cleaning of the residualmaterials in a cylindrical space of a lower area of a blast furnace during furnace stopping can be realized, meanwhile, the needs of the harsh environment of the limited operating space and the variable positions are met, quick changes of the site operating conditions can be met, meanwhile, the effective radius of a tail non-slip tensioner can be adjusted to change the tightness of a temperature-resistant tape according to the use situation, the safety of operation is increased, the service life of the device is prolonged, the needs of operation in harsh environments are met, and the device better serves an operator.

Description

technical field [0001] The invention relates to the technical field of blast furnace hearths, in particular to a device for cleaning residual materials in the lower part of a large blast furnace hearth. Background technique [0002] In the production of modern large-scale blast furnaces, in order to improve the economic and technical indicators of blast furnace production and maintain the safe and long-life operation of blast furnace body production, the furnace is often shut down for intermediate repairs, and the damaged cooling staves operating at high temperatures above the tuyere are replaced to quickly restore blast furnace production. Minimize the loss of blast furnace shutdown. [0003] Based on the characteristics of the blast furnace production process, the material can only be lowered to the tuyere area after the furnace is shut down, and the residual material needs to be cleaned to the tap area after the blast furnace resumes production. The traditional cleaning m...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device for cleaning the residual material in the lower part of the hearth of a large blast furnace. The material is cleaned on the belt conveyor and sent out of the furnace; due to manual work in a limited space, coupled with uncertain factors such as residual gas, temperature, dust, and steam in the furnace, the cleaning efficiency takes a long time, especially for materials in the lower 3 to 4m. cleanup problem
