A valve chest with a slag retaining mechanism

Abstract

The present application relates to the technical field of blast furnace front equipment, and particularly relates to a valve stand chamber with a slag blocking mechanism, which comprises a valve stand chamber main body and a visible window arranged on the side wall of the valve stand chamber main body, a first pulley is arranged on the outer side wall of the valve stand chamber main body and located above the visible window, a steel wire rope is further arranged on the first pulley and extends to the inside of the valve stand chamber main body through a through hole in the side wall of the valve stand chamber main body, one end of the steel wire rope located outside the valve stand chamber main body is connected with a slag blocking plate, and the other end of the steel wire rope located inside the valve stand chamber main body is connected with an electric hoist, the area of the slag blocking plate is larger than that of the visible window, so that the electric hoist controls the steel wire rope to lower the slag blocking plate to block the visible window. During the front furnace operation, the slag blocking plate can be controlled to be lowered and block the window area, so as to avoid the high-temperature slag from splashing into the window, avoid the strong heat radiation from burning the indoor operator through the glass, reduce the risk of safety accidents from the window dimension, and be suitable for the blast furnace front scene.
