A sintered anti-blocking grate

Abstract

The present invention provides a sintered anti-blocking grate, which comprises a grate body. Ends are arranged at both ends of the upper part of the grate body, and hooks are arranged at both ends of the lower part of the grate body. A slot is formed between the ends and the hooks. The top surface of the grate body is provided with a top convex rib, which protrudes from the top surface of the grate body, the bottom side of the grate body is arched, and the front and rear sides of the grate body are arranged symmetrically. The first inclined surface, the first inclined surface is inclined towards the inside of the grate body, the left side, the right side and the bottom side of the first inclined surface are all provided with side convex ribs, which protrude symmetrically towards the front and rear sides respectively, Moreover, the overall thickness between the front and rear symmetrical side ribs gradually decreases as the two first inclined surfaces incline and approach, and is always smaller than the thickness of the top rib. The sintered anti-blocking grate provided by the invention does not block the gaps between the grates during use, has large ventilation area, light weight and long service life.

Description

technical field [0001] The invention relates to the field of sintering equipment, more specifically, to a sintering anti-blocking grate. Background technique [0002] Usually, the sintering grate is installed on the sintering trolley to support the material and ventilate through the grate gap to complete the key part of the material sintering process. The number of grates for a different type of sintering machine needs tens of thousands to hundreds of thousands of pieces for one assembly. Its main function is to dredge the waste gas with high temperature and high dust content generated during the sintering process under the condition of high temperature and high oxidizing atmosphere. [0003] The sintering process generally requires a large amount of combustion-supporting air to complete, which is obtained by the negative pressure formed on the surface of the sintered material by the air supply system through the gaps between the grates embedded in the bottom of the trolley...

AI Technical Summary

Problems solved by technology

Conventionally designed sintering grate gaps are easily blocked by dust and sintering material powder mixed with sintering waste gas. The clogged grate gaps form a huge resistance to air supply, which is the main cause of low utilization efficiency of sintering combustion-supporting air and low sintering production efficiency. reason

The low utilization rate of combustion-supporting air has become a major obstacle to increase production and reduce energy consumption in the sintering production process
