Improved flue ash discharging device

Abstract

The utility model relates to the field of steel manufacturing, in particular to an improved flue ash discharging device which comprises an ash hopper. The double-layer cinder valve comprises an upper valve body and a lower valve body, a feeding port of the upper valve body is communicated with a discharging port of the ash hopper, a feeding port of the lower valve body is communicated with a discharging port of the upper valve body, a valve A is arranged in the upper valve body, a valve B is arranged in the lower valve body, and a material ramming rod is installed on the valve A; and a communicating pipe is arranged between the ash hopper and the upper valve body. According to the improved flue ash discharging device, the material ramming rod is arranged in the valve body A, when the valve body A is closed, a material accumulation layer in the ash hopper can be directly damaged, the material accumulation layer is changed into a loose state from a new state, materials are easy to fall, meanwhile, the communicating pipe is arranged, the pressure in the upper valve body and the pressure in the ash hopper are the same, and the ash discharging efficiency is improved. Therefore, materials in the ash hopper can fall into the upper valve body more easily.
