Description

Distributing device for sintering machine trolley

Technical Field

The utility model relates to the technical field of iron-making sintering equipment, in particular to a distributing device for a sintering machine trolley.

Background

Due to the influence of various factors such as moisture, the spreading of the sintering machine is uneven, and the phenomenon of trolley grooving exists. The place where the trench is pulled is the place where the whole table top is the looest, the air permeability is good, and the wind is the easiest to pass through, so that the effective air quantity at the trench is greatly increased, the vertical sintering speed is too fast, and the flat place of the material surface is under-burned. In addition, the thickness of the material layer at the position of the pull groove is thinner than that at the position of the leveling, and the material layer can be burnt out in advance under the condition of the same vertical sintering speed, so that sintering fluctuation is caused. The edge effect causes the sintering machine to have underburned edge material, the sintering ore presents dark red, the agglomerate is less, the inclusion is more, most of the material is transferred into the return ore after crushing and screening, and the edge yield is reduced. Meanwhile, low-melting-point substances in the red return ores are few, and the quality of the return ores is reduced. The edge effect not only affects the sintering process of the edge material, but also causes uneven distribution of airflow on the material surface, unreasonable heat system, lagged vertical sintering speed in the middle, poor air permeability, different vertical sintering speeds aggravate uneven distribution of airflow, form vicious circle, and bring great difficulty to stable operation of sintering production.
