Problems solved by technology

Therefore, in the sintering trolley, the porosity of the sintered ore gradually decreases from top to bottom, and the accumulation gradually becomes more compact. This phenomenon not only increases the requirements for the ventilation pressure, but also makes it difficult to sinter the closely packed sintered ore in the lower layer, and is prone to Incomplete sintering

Abstract

The invention relates to a belt-type sinterer with a high utilization rate. The sinterer comprises a trolley, a trolley running rail device and a crawler belt device. The trolley running rail device comprises a concentric-square-shaped rail. An upper-layer rail and a lower-layer rail of the concentric-square-shaped rail are parallel up and down. The trolley runs cyclically on the concentric-square-shaped rail, and a material opening is formed in the top of the trolley. The crawler belt device comprises crawler belt plates, a crawler belt driving wheel and crawler belt driven wheels. The crawler belt driving wheel and the crawler belt driven wheels are rotationally connected to a fixed support. The crawler belt driving wheel is located at the position, above the trolley, of the ending position of the upper-layer rail. The crawler belt driven wheels is located at the preset position, below the trolley, of the lower-layer rail. The multiple crawler belt plates are hinged in sequence to form a crawler belt chain, the crawler belt driving wheel and the crawler belt driven wheels are sleeved with the crawler belt chain, the crawler belt chain and the trolley are driven by the crawler belt driving wheel to move synchronously and cyclically, and the width of the crawler belt chain is not smaller than that of the material opening of the trolley. The outer side of the crawler belt chainis connected with the material opening of the trolley in a closed manner. According to the belt-type sinterer, the problems that sintered ore is too close, and holes are small are effectively solved,and the requirement for air extraction pressure is reduced.

Description

technical field [0001] The invention relates to the technical field of sintering machines, in particular to a belt-type sintering machine with high utilization rate. Background technique [0002] Blast furnace ironmaking is one of the main methods of smelting metal iron in modern times. In order to improve the smelting strength of blast furnace ironmaking, enhance the gas permeability of the furnace and increase the taste of iron ore in the furnace, iron ore powder is often made into sintered iron ore powder by sintering method. Mine is used for blast furnaces. [0003] The sintering process is mainly carried out on the sintering trolley. The sintering trolley travels along the track of the sintering machine. At a certain position, the material distribution device lays the sintering material made of finely ground concentrate powder, flux, fuel and binder on the sintering trolley. . After the sintering trolley is filled with sinter, it travels along the track to the positio...
