[0002] In the iron and steel metallurgical industry, sintered ore is the main raw material for blast furnace ironmaking, and its quality directly affects the blast furnace smelting efficiency and pig iron quality. The sintering process is a key link in sintering production. The uniformity of the charge, the permeability of the charge layer, and the rationality of the particle size distribution of the material have a decisive impact on the sufficiency of the subsequent sintering reaction and the strength and reducibility of the sintered ore.

The distribution rake can distribute the material pile in front of it to the material-deficient area, improving the material distribution state and ensuring that the density of the mixture is approximately the same along the width and length of the trolley, thereby achieving a basically consistent vertical combustion speed during sintering and avoiding localized raw material or premature sintering in the sintered ore layer; moreover, the distribution rake also has a loosening effect, giving the mixture layer good air permeability and improving the quality of the sintered ore.

[0004] However, in actual use, the rake nails of the above-mentioned fabric feeding device are in direct contact with the material and are subjected to the scouring and friction of the material for a long time, which causes the rake nails to wear and affect their service life. Summary of the Invention

[0029] like Figure 1 and Figure 2As shown, this application provides a sintered ore feeding device, including a feeding frame 1 and a multi-roller feeder 2 inclinedly arranged on the feeding frame 1. The multi-roller feeder 2 is prior art and will not be described in detail here. The feeding frame 1 is provided with a feeding rake 3, which includes a rake crossbar 31, multiple rake spikes 32, and multiple contact blocks 33. The rake crossbar 31 is arranged on the feeding frame 1, the multiple rake spikes 32 are spaced apart along the length direction of the rake crossbar 31, and the contact blocks 33 correspond one-to-one with the rake spikes 32. 3. It is detachably mounted on the side of the rake nail 32 that contacts the material; in use, the feeding frame 1 is fixed on the sintering trolley frame in the prior art, and the feeding end of the multi-roller feeder 2 is located below the circular roller feeder in the prior art. In the prior art, the mixture in the sintering machine's feed trough is discharged onto the multi-roller feeder 2 through the circular roller feeder. The rotation of the feeding rollers of the multi-roller feeder 2 increases the speed at which the mixture rolls down, and also causes the mixture to tumble up and down; most of the larger particles in the mixture... The material falls to the lower layer of the sintering trolley at a relatively fast falling speed, while the smaller particles fall to the upper layer through the gap between the rollers of the multi-roller distributor 2 at a relatively slower falling speed. This forms a mixed material layer on the sintering trolley with larger particles at the bottom and smaller particles at the top. As the sintering trolley operates, the rakes 3 on the distribution frame 1 simultaneously participate in the material distribution operation. The detachable contact blocks 33 on the rake 32 directly act on the material, using their pushing and dispersing action to eliminate localized accumulation in the material flow, adjust the flatness and density distribution of the material layer, and improve the sintering effect. Compared with existing technologies, by setting detachable contact blocks 33 on the contact side of the rake 32, the contact blocks 33 become the components that directly bear the friction and impact of the material, effectively avoiding wear on the rake 32 itself and extending its service life. When the contact blocks 33 wear out, they can be disassembled and replaced individually, without replacing the entire rake 32 or the rake crossbar 31, thus reducing costs.

[0030] like Figure 2 As shown, the rake crossbar 31 is provided with a through hole 311, and the material contact block 33 is adapted to the through hole 311. The top of the material contact block 33 is provided with an anti-detachment part 331. The material contact block 33 is inserted into the through hole 311 and the anti-detachment part 331 abuts against the top of the rake crossbar 31. The cross section of the material contact block 33 is triangular, and one corner of the material contact block 33 faces the direction of material movement. The matching design of the through hole 311 and the anti-detachment part 331 not only ensures the firmness of the installation of the material contact block 33 and prevents it from falling off under the impact of the material, but also simplifies the disassembly and assembly process of the material contact block 33 and facilitates the quick replacement of worn parts. The triangular cross section of the material contact block 33, with its pointed corner facing the direction of material movement, reduces the impact force and frictional wear of the material on the material contact block 33 and extends the service life of the material contact block 33.

[0031] like Figure 1 and Figure 2As shown, the surface of the contact block 33 is coated with a wear-resistant coating. The wear-resistant coating can reduce the wear of the contact block 33 caused by material friction and impact, and extend the replacement cycle of the contact block 33. The wear-resistant coating can be an alumina ceramic coating, a tungsten carbide ceramic coating, etc.

[0032] like Figure 1 As shown, the fabric rack 1 is designed with multiple U-shaped placement slots 4 of varying depths. The rake crossbar 31 is adapted to the U-shaped placement slots 4, with the end of the rake crossbar 31 placed inside the U-shaped placement slot 4. The cross-section of the rake crossbar 31 is square. The design of the U-shaped placement slots 4 of varying depths allows the height of the rake crossbar 31 to be adjusted by selecting different slot positions, flexibly adapting to different fabric laying conditions and improving the versatility of the device. The square cross-section of the rake crossbar 31, in conjunction with the U-shaped placement slots 4, can effectively prevent the rake crossbar 31 from rotating or shifting during operation, ensuring the stability of the action direction of the contact block 33. At the same time, the placement installation structure simplifies the disassembly and assembly process of the rake crossbar 31, making maintenance and adjustment easier.

[0033] like Figure 1 and Figure 3 As shown, a rotating shaft 5 is provided on the side of the fabric rake 3 away from the multi-roller fabric feeder 2. The rotating shaft 5 is rotatably mounted on the fabric frame 1. A flat material plate 6 is fixed on the rotating shaft 5. One end of the rotating shaft 5 passes through the fabric frame 1 and is connected to a disc 7. The disc 7 has multiple first limiting through holes arranged in a ring array. The fabric frame 1 has a second limiting through hole. A pin 8 is inserted through the second limiting through hole and one of the first limiting through holes. The cooperation between the rotating shaft 5, the disc 7, the limiting through holes, and the pin 8 realizes the flexible adjustment and stable fixation of the angle of the flat material plate 6. The posture of the flat material plate 6 can be adjusted according to the material layer thickness requirements to improve the flatness of the material layer. The design of the first limiting through holes in the ring array provides multiple angle selections to meet the needs of different working conditions. The pin 8 fixing method is simple to operate and facilitates quick angle adjustment and locking.

[0034] like Figure 1 and Figure 3 As shown, the side of the flat plate 6 that contacts the material is detachably equipped with a wear-resistant liner 9. When the flat plate 6 is used to level the material layer, the wear-resistant liner 9 is in direct contact with the material and bears the friction and impact of the material, so that the flat plate 6 body is protected from direct wear by the material and the service life of the flat plate 6 is extended. When the liner is worn, only the liner needs to be replaced, and there is no need to repair or replace the entire flat plate 6.

[0035] like Figure 1 and Figure 3As shown, the upper end of the wear-resistant liner 9 is bent to form a hook 91. The wear-resistant liner 9 is hung on the flat plate 6 through the hook 91. A limiting block 61 is provided on the side of the flat plate 6 away from the wear-resistant liner 9. A limiting groove 92 that matches the limiting block 61 is provided on the side of the hook 91 of the wear-resistant liner 9. By utilizing the suspension effect of the hook 91 and the snap-fit ​​cooperation of the limiting block 61 and the limiting groove 92, the wear-resistant liner 9 can be quickly positioned and firmly fixed on the side of the flat plate 6 that contacts the material. During the process of the flat plate 6 leveling the material layer, the wear-resistant liner 9 can stably withstand the friction and impact of the material without displacement. Moreover, the wear-resistant liner 9 can be firmly connected to the flat plate 6 without additional fasteners, which greatly simplifies the installation and disassembly process of the wear-resistant liner 9 and facilitates the quick replacement of the worn liner.

[0036] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
