Description

Technical Field

[0001] This utility model relates to the field of sintered fabric technology, specifically to a device for uniformly distributing sintered mixtures. Background Technology

[0002] Sintering mix, as the name suggests, is a material used for sintering, composed of a mixture of various raw materials. It mainly consists of iron-containing raw materials, flux, fuel, and a certain amount of recycled ore. These raw materials are mixed in a specific ratio, granulated, and distributed before being fed into a blast furnace for sintering, ultimately yielding sintered ore with a certain strength and permeability. Sintered aggregates play a crucial role in steel production. Firstly, as one of the main furnace charges in blast furnace smelting, they provide a stable iron source and an appropriate amount of flux, ensuring the smooth operation of blast furnace smelting. Secondly, the permeability of the sintered aggregate directly affects the gas flow distribution and reduction reaction within the blast furnace. However, in the application of traditional sintering mixture feeding devices, the sintering mixture is prone to excessive accumulation inside, causing blockage at the discharge end. When fed into the blast furnace for smelting, local accumulation or shortage of material is likely to occur.

[0003] Based on this, we propose a uniform distribution device for sintering mixtures. Utility Model Content

A transmission assembly, which is mounted between the feed roller and the combing assembly, is used to provide power to the feed roller and the combing assembly.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0024] like Figures 1-5 As shown, it illustrates a uniform distribution device for sintering mixtures according to an embodiment of the present invention. Some examples include: The material storage box 1 has a material supply box 2 fixedly connected to its bottom end. The material supply box 2 has a material supply roller 3 rotatably connected inside. Multiple material loading grooves 4 are opened on the outer side of the material supply roller 3. An adjusting plate 6 is slidably connected inside each material loading groove 4. A loading cavity 5 is opened in the middle of the material supply roller 3. Adjustment component 7 is assembled inside the mounting cavity 5. Adjustment component 7 is used to adjust the volume of the material loading trough 4 in conjunction with adjustment plate 6. The bottom end of the feeding box 2 is fixedly connected to the discharge pipe 8. The combing assembly 9 is assembled at the bottom of the storage box 1 and is used to turn over the sintering mixture. The transmission assembly 10 is assembled between the feed roller 3 and the comb assembly 9 and is used to provide power to the feed roller 3 and the comb assembly 9.

[0025] For example, such as Figure 2 As shown, the bottom of the storage tank 1 is funnel-shaped, and both ends of the storage tank 1 are provided with residual feedback windows. Through the structural characteristics of the storage tank 1, the mixed material inside the storage tank 1 can be collected at its bottom, avoiding the mixed material remaining inside the storage tank 1. In addition, with the setting of the residual feedback window, the consumption of the mixed material inside the storage tank 1 can be displayed intuitively.

[0026] For example, such as Figure 2 As shown, stabilizing rings are fixedly connected to the edges of both ends of the feeding roller 3, and stabilizing grooves are fixedly connected to both ends inside the feeding box 2. The stabilizing rings are also rotatably connected inside the stabilizing grooves. Through the structural cooperation of the stabilizing rings and stabilizing grooves, the feeding roller 3 can be supported from both ends to ensure the connection effect between the feeding roller 3 and the feeding box 2. At the same time, alloy balls can also be set inside the stabilizing grooves to improve the smoothness of the rotation of the feeding roller 3.

[0027] For example, such as Figure 3 and Figure 4 As shown, the adjustment component 7 includes: The placement frame 11 is fixedly connected inside the mounting cavity 5. An adjusting shaft 12 is rotatably connected to the middle of the placement frame 11. Both ends of the adjusting shaft 12 are fixedly connected to a transmission plate 13. Push plates 14 corresponding to the adjusting plates 6 are rotatably connected to the outer side of the transmission plate 13. Each adjusting plate 6 has a push rod 15 extending into the mounting cavity 5 fixedly connected to its bottom end. The end of the push plate 14 away from the transmission plate 13 is rotatably connected to the corresponding push rod 15. The threaded section 16 is located at one end of the adjusting shaft 12 near the settling frame 11, and the outer side of the threaded section 16 is threaded with an anti-rotation cylinder 17.

[0028] For example, such as Figure 3 As shown, a support frame is fixedly connected to the middle of the mounting cavity 5. A support hole is opened in the middle of the support frame, and the adjusting shaft 12 is also connected to the inside of the support hole through a ball bearing. By setting the support frame, the middle of the adjusting shaft 12 can be auxiliaryly supported, so as to avoid uncontrollable shaking of the adjusting shaft 12 when it rotates.

[0029] For example, such as Figure 3 As shown, an eccentric handle is fixedly connected to one end of the adjusting shaft 12 near the anti-rotation cylinder 17, and the outer side of the eccentric handle is provided with anti-slip texture. With the setting of the eccentric handle, the adjusting shaft 12 can be rotated conveniently by means of the lever principle, and the anti-slip texture makes it easier for people to hold and avoid slipping.

[0030] The combing assembly 9 includes: The comb shaft 18 is rotatably connected to the bottom of the storage box 1. The comb plate 19 is fixedly connected to the middle of the comb shaft 18, and the drive sprocket 20 is fixedly connected to one end of the comb shaft 18.

[0031] like Figure 5 As shown, it illustrates the transmission assembly 10 in another embodiment of the present invention. In some examples, the transmission assembly 10 includes: The drive shaft 21 is rotatably connected to the middle of one end of the feeding box 2. The end of the drive shaft 21 located inside the feeding box 2 is also fixedly connected to the feeding roller 3. A drive sprocket 22 is fixedly connected to the outside of the drive shaft 21, and the drive sprocket 22 is connected to the drive sprocket 20 by a chain. A drive motor 23 is fixedly connected to one end of the feeding box 2. A drive spur gear 24 is fixedly connected to the output end of the drive motor 23. A reduction spur gear 25 is fixedly connected to the outer side of the drive shaft 21, and the reduction spur gear 25 meshes with the drive spur gear 24.

[0032] More specifically, the diameter of the transmission spur gear 24 is smaller than the diameter of the reduction spur gear 25, thereby enabling control of the rotational speed of the transmission shaft 21; In this embodiment, an extension support frame is fixedly connected to one end of the feeding box 2, and the drive motor 23 is bolted to one end of the extension support frame.

[0033] Working principle: First, the storage tank 1 is positioned at the feed inlet of the blast furnace using a bracket. Then, the sintered mixture is poured into the storage tank 1 and concentrated. During blast furnace smelting, the drive motor 23 is started, which causes the drive spur gear 24 to move the reduction spur gear 25. This, in turn, drives the feed roller 3 to rotate through the drive shaft 21. This causes the loading trough 4 to pass under the storage tank 1 in sequence. When the loading trough 4 rotates and corresponds to the bottom of the storage tank 1, some of the mixture inside the storage tank 1 will enter the loading trough 4. As the feed roller 3 continues to rotate, the loading trough 4 with the mixture will rotate to the feed pipe 8. Finally, the mixture in the loading trough 4 will be introduced into the blast furnace for smelting through the feed pipe 8. Since the rotation speed of the drive shaft 21 is constant, the mixture in the storage tank 1 can be evenly supplied to the blast furnace for smelting through the uniform rotation of multiple loading troughs 4. Furthermore, during the rotation of the drive shaft 21, the power of the drive shaft 21 can be transmitted to the comb shaft 18 through the chain, causing the comb shaft 18 to drive the comb plate 19 to flip the mixture in the storage box 1, thus preventing the mixture from clogging the bottom of the storage box 1. Furthermore, the rotatable anti-rotation cylinder 17, connected to the threaded section 16, allows the anti-rotation cylinder 17 to move away from the placement frame 11, thereby reducing the friction of the rotating adjusting shaft 12. Subsequently, the adjusting shaft 12 drives the transmission plate 13 to rotate. Since the push plate 14 is connected between the push rod 15 and the transmission plate 13, when the transmission plate 13 rotates, it can push the push rod 15 through the push plate 14, causing the adjusting plate 6 to slide inside the material loading trough 4, thereby adjusting the volume of the material loading trough 4 and controlling the amount of mixed material distributed.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
