The above structure addresses the shortcomings of the prior art by proposing an improved technical solution. In this structure, multiple scraper chain components 1 are combined and connected to form the scraper chain structure for the blast furnace ore bin dust removal scraper. The scraper chain structure passes through the blast furnace ore bin and can move along the blast furnace ore bin under the control of a drive component, thereby scraping away dust from inside the blast furnace ore bin and moving it to the outside of the blast furnace ore bin. Each scraper assembly 1 includes a body part 2, an upper connecting part 3 with an upper through hole 4 on the upper part of the body part 2, a lower connecting part 5 with a lower through hole 6 on the lower part of the body part 2, and a scraper plate 7 protruding to the side on each side of the body part 2. The scraper plate 7 and the body part 2 are integrally structured, with high overall rigidity and strength. The scraper plate 7 extends outward, and its width gradually decreases from one end near the body part to the outer end, further ensuring the rigidity and strength between the scraper plate 7 and the body part, making it less prone to deformation and breakage during use. The length between the outermost ends of the scraper plates 7 on both sides is slightly less than the width of the blast furnace trough. At the same time, both the body part 2 and the scraper plate 7 have a certain thickness, which can reliably achieve the purpose of dust removal. The scraper chain structure of the blast furnace ore bin dust removal scraper machine described in this utility model has a simple structure, which greatly improves the rigidity and strength of the scraper chain assembly (chain link), extends the service life of the scraper, ensures good dust removal effect, and has the advantages of low manufacturing cost, high efficiency, and continuous and stable dust collection effect.

With this structure, the upper connecting portion 3 of one scraper assembly 1 can extend between the inner sides of the first lower connecting portion 10 and the second lower connecting portion 11 of another scraper assembly 1. Then, the corresponding pins simultaneously pass through the upper through hole 4 of the upper connecting portion 3 and the lower through hole 6 of the lower connecting portion 5, achieving a reliable movable connection between two adjacent scraper assemblies 1.

[0028] The scraper plate 7 includes a first scraper plate 12 and a second scraper plate 13. In the above structure, the first scraper plate 12 extends to one side of the body portion, and the center line of the first scraper plate 12 is perpendicular to the center line of the body portion 2. The second scraper plate 13 extends to the other side of the body portion, and the center line of the second scraper plate 13 is perpendicular to the center line of the body portion 2.

[0029] A first reinforcing rib 14 is provided at the joint between the first scraper plate 12 and the first lower connecting part 10, and a second reinforcing rib 15 is provided at the joint between the second scraper plate 13 and the second lower connecting part 11. In this structure, the reinforcing ribs further improve the strength of the main body and the scraper plate.

[0030] Multiple scraper assembly 1 form a ring-shaped scraper structure for a blast furnace ore bin dust removal scraper, which is mounted on a drive wheel and a driven wheel. The scraper structure is located inside the blast furnace ore bin. The drive wheel is connected to the drive shaft of a drive motor.

This integral structure simplifies the manufacturing process and provides good overall strength and rigidity.

[0032] The scraper chain structure of the blast furnace ore bin dust removal scraper of this utility model is configured with multiple scraper chain components 1. These components are combined and connected to form the scraper chain structure. The scraper chain structure moves along the blast furnace ore bin under the control of a drive component, scraping away dust from inside the bin and carrying it outside. Each scraper chain component 1 includes a body part 2, an upper connecting part 3 with an upper through hole 4, a lower connecting part 5 with a lower through hole 6, and a scraper plate 7 protruding to the side on each side of the body part 2. The scraper blade 7 and the main body 2 are an integral structure with high overall rigidity and strength. The scraper blade 7 extends outward, and its width gradually decreases from one end near the main body to the outer end, further ensuring the rigidity and strength between the scraper blade 7 and the main body, making it less prone to deformation and breakage during use. The length between the outermost ends of the scraper blades 7 on both sides is slightly less than the width of the blast furnace ore bin. At the same time, both the main body 2 and the scraper blade 7 have a certain thickness, which can reliably achieve the purpose of dust removal.
