Description

Technical Field

[0001] The invention relates to the technical field of iron and steel metallurgical production, and in particular to a modular anti-wear structure of a sintering machine bellows partition. Background Art

[0002] Sintering machines are suitable for sintering operations in large-scale ferrous metallurgy sintering plants. They are the core equipment in the draft sintering process, agglomerating concentrate and enriched ore powders of varying composition and particle size into agglomerates while partially eliminating harmful impurities such as sulfur and phosphorus from the ore. Sintering machines are available in various lengths and widths, depending on the sintering area. Users can select the appropriate size based on their production capacity or site conditions. A larger sintering area results in higher production output.

[0003] Currently, most sintering machines use long, flat-topped bellows partitions 500-600mm wide. Castable material is poured into the steel structure. During normal production, fine powder or small-particle sintered ore from the sintering machine trolleys easily falls through the gaps in the grate. The flat structure of the bellows partitions makes it easy for material to accumulate on the top of the partitions. During trolley operation, this accumulated material scrapes against the bottom of the trolley, causing damage and loss of the partition's refractory material, deformation of the steel structure, and air flow between adjacent bellows. This also leads to frequent maintenance and increased labor and material costs. Summary of the Invention

[0004] In order to solve the problem in the prior art that material easily accumulates on the top of the bellows partition, causing damage to the bottom of the bellows partition when the trolley is running, the present invention provides a modular anti-wear structure for the bellows partition of a sintering machine, which reduces the maintenance frequency of the bellows partition of the sintering machine and the air leakage rate of the system, and provides a modular anti-wear structure for the bellows partition of a sintering machine with a long life.

[0005] The present invention provides a modular anti-wear structure for a sintering machine bellows partition, comprising two steel plates, one end of each steel plate connected to the other, forming a triangular steel plate composite structure. Flat steel edge banding structures are provided at each end of the steel plate composite structure, and a tortoise shell mesh is provided on the upper portion of the steel plate composite structure, which is provided with a refractory material protective layer. The triangular steel plate composite structure, which acts like a roof ridge, prevents material accumulation and, therefore, prevents damage to the partition caused by scraping from the bottom of the trolley during operation.

[0006] Furthermore, the angle formed by the two steel plates is set to 90°, which is convenient for modular production and also facilitates a smooth transition connection between the steel plate composite structure and the edge of the bellows.

[0007] Furthermore, the thickness of the steel plate is set to 6 mm.

[0008] Furthermore, the flat steel edge sealing structure includes flat steel, and the angle formed by the flat steel and the steel plate combined structural member is set to 90 degrees, which is convenient for modular production, easy to receive refractory materials and fixed welding during installation.

[0009] Furthermore, the flat steel is connected to the steel plate composite structure by welding.

[0010] Furthermore, the thickness of the flat steel is set to 5 mm and the width is set to 25 mm.

[0011] Furthermore, the thickness of the tortoise shell mesh is set to 2mm-3mm.

[0012] Furthermore, the tortoise shell mesh is combined with the steel plate to form a structural member by welding.

[0013] The beneficial effects of the present invention are as follows: the top of the sintering machine bellows partition is designed as a ridge-shaped triangular steel plate composite structure, which avoids the accumulation of material on the top of the sintering machine bellows partition, and avoids serious damage to the partition structure caused by the accumulated material and the scraping of the bottom of the sintering machine trolley; the high-strength, wear-resistant, and high-temperature resistant refractory material protective layer increases the high-temperature resistance and wear resistance of the partition structure, extends the service life, improves production efficiency, and reduces production costs; the modular structural design can be manufactured in advance, is easy to install, and reduces the downtime of the sintering machine.
