Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of sintering machines, and in particular, to a sintering material processing device. Background Art

[0002] The sintering machine is a key step in the iron-making process. Its purpose is to mix the iron-containing materials with the fuel, undergo a series of physical and chemical changes in the sintering device, and finally sinter them into blocks for use in subsequent blast furnace iron-making.

[0003] In the actual sintering process, after the sintering material is evenly spread on the sintering trolley, it slowly enters the ignition device to ignite the upper material, and gradually passes through the channel below where air is continuously pumped out and is sintered under the action of wind, ensuring that all the materials in the sintering trolley are processed.

[0004] In the prior art, iron-containing materials are usually mixed with coke and other materials and ignited. However, during the combustion process, although there is a fan to continuously extract air, the combustion process is not relatively stable. Since the chemical changes involved are very complex, actual control is difficult to achieve. Spraying a certain amount of water vapor on the sintering material surface can increase the humidity of the sintering material, and can also reduce the ignition point of the fuel to a certain extent so that the fuel can play a certain combustion-supporting role during the combustion process. However, in actual operation, the amount of steam actually sprayed on the sintering material is small, and a large amount of steam will dissipate into the external environment, resulting in a lot of steam waste. Summary of the invention

[0005] To overcome the above defects, an embodiment of the present disclosure provides a sintering material processing device, which solves the technical problem in the related art that when steam is sprayed on the sintering material, the amount of steam actually sprayed on the sintering material is small, a large amount of steam will escape into the external environment, and a lot of steam will be wasted.

[0048] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0049] like Figure 1 to Figure 9 As shown, it shows a sintering material processing device in one embodiment of the present disclosure. In the iron-making process, the sintering machine plays a vital role. It mixes iron-containing materials with fuel, and sinters them into blocks through a series of physical and chemical changes to provide raw materials for subsequent blast furnace iron-making.

[0050] This device is mainly used for steam spraying the sintering material on the sintering trolley 100, and its core structure includes a support frame 110, a loosening frame 210 and a loosening tooth 220. The support frame 110 provides a support structure for the entire device and allows several sintering trolleys 100 to pass through smoothly. It is like the skeleton of the entire device, ensuring that other components can be stably installed and operated. The support frame 110 is usually made of a solid metal material to withstand various forces during the operation of the device. Its outer dimensions are made according to the size and running track of the sintering trolley 100 to ensure that the sintering trolley 100 can pass smoothly underneath it and maintain a suitable positional relationship with the loosening frame 210 and other components. The loosening frame 210 is slidably arranged relative to the support frame 110, and has a ventilation space 211 inside that is connected to the external steam pipeline, providing a channel for the transportation of steam so that the steam can reach the loosening tooth 220 and then spray onto the material. The loosening rack 210 is slidably arranged relative to the support frame 110, and has a ventilation space 211 inside that is connected to the external steam pipeline. The sliding function of the loosening rack 210 enables the device to process sintered materials of different positions, thicknesses or compactness, thereby enhancing the adaptability of the device. The connection between the ventilation space 211 and the external steam pipeline ensures that steam can be stably supplied to the loosening teeth 220, providing a guarantee for achieving uniform and effective steam spraying. A plurality of loosening teeth 220 are arranged at intervals on the loosening rack 210, and follow the loosening rack 210 to slide into or leave the sintered material to loosen the surface of the material. At the same time, the steam spray holes 221 thereon are connected to the ventilation space 211 for spraying steam. The loosening teeth 220 are usually tooth-shaped, which is convenient for inserting into the material for loosening operation.

[0051] In the actual working process, when the sintering trolley 100 carries the sintering material and slowly moves to the bottom of the processing device, the loosening rack adjusts its position through the sliding structure between it and the support frame 110. As the loosening rack 210 slides, the loosening teeth 220 follow and enter the sintering material. The loosening teeth 220 insert into the surface of the material by virtue of their own tooth shape, loosen the material, and increase the gap between the material particles. At the same time, the external steam enters the ventilation space 211 through the steam pipeline connected to the ventilation space 211, and then evenly sprays from the steam spray holes 221 on the loosening teeth 220 to the loosened material surface. The steam spray holes 221 are located on both sides of the loosening teeth 220, and will not enter the inside of the sintering material with the sliding of the loosening teeth 220, but are always above the sintering material. When the loosening teeth 220 slide, the height of the steam spray holes 221 from the surface of the sintering material changes, thereby changing the depth of the steam spraying to the material. At the same time, when the steam is sprayed, and due to the change in the material structure, it can penetrate deeper into the material. In this way, steam not only increases the humidity of the material, but also utilizes the characteristic of lowering the ignition point of the fuel to make the sintering process more controllable, thereby improving the sintering quality and making the sintering process more stable and efficient.

[0052] The advantages of this solution are: the multiple loosening teeth 220 arranged at intervals loosen and spray steam on the materials in turn during the sliding process of the loosening rack 210. Compared with the traditional spraying method of a single or a small number of nozzles, more uniform steam spraying can be achieved over a larger area, ensuring that the humidity of each part of the sintered material is relatively consistent, and improving the stability of the sintering quality. The loosening effect of the loosening teeth 220 on the surface of the material changes the structure of the material, allowing steam to penetrate into the material more easily, effectively solving the problem of shallow depth of steam entering the material in the prior art, and better playing the role of steam in assisting combustion. The sliding setting of the loosening rack 210 relative to the support frame 110 enables the device to flexibly adjust the processing position and method of the sintered material according to different production needs, enhances the adaptability to various sintering conditions, and meets the diversified needs in the actual production process.

[0053] In some examples, the switching sleeve 310 is rotatably arranged relative to the support frame 110, and a plurality of guide slots 311 are distributed at intervals on the upper circumference thereof, and a loosening rack 210 is slidably arranged in each guide slot 311. The core idea of ​​this design is to change the position of the guide slot 311 by rotating the switching sleeve 310, and then adjust the working position of the loosening rack 210 for better maintenance. A plurality of elastic members 320 are respectively connected between the loosening rack 210 and the switching sleeve 310, and their main function is to provide an elastic pulling force for the loosening rack 210, so that the loosening teeth 220 on the loosening rack 210 can be automatically retracted into the guide slot 311 when no external force is applied. Two cams 330 are respectively arranged at the two ends of the switching sleeve 310, and their rotation axes are colinear with the rotation axis of the switching sleeve 310. The loosening rack 210 is provided with a pushed portion 212. When the cam 330 rotates, its side wall abuts against the pushed portion 212, thereby pushing the loosening rack 210 to slide in the guide slot 311, so that the loosening teeth 220 can pass outward or retract inward from the guide slot 311.

[0054] In actual use, when the sintered material needs to be processed, first, according to the distribution of the material, the switching sleeve 310 is rotated by the driving mechanism to adjust the material loosening rack 210 to a suitable position. At this time, the elastic member 320 is in a natural or slightly stretched state, and the loosening teeth 220 are located in the guide groove 311 under the pulling force of the elastic member 320. Then, the cam 330 is driven to rotate. Under the push of the cam 330, the loosening rack 210 overcomes the pulling force of the elastic member 320 and slides outward along the guide groove 311, so that the loosening teeth 220 pass through the guide groove 311 and enter the sintered material to loosen the material. When the cam 330 continues to rotate, its contact position with the pushed part 212 changes, and the thrust gradually decreases. When the pulling force of the elastic member 320 is greater than the thrust of the cam 330, the elastic member 320 pulls the loosening rack 210 back, so that the loosening teeth 220 are retracted into the guide groove 311. By controlling the rotation frequency and angle of the cam 330 , the intermittent loosening operation of the loosening teeth 220 on the material can be achieved to meet different process requirements.

[0055] In some examples, a plurality of bearing seats 410 are disposed on the support frame 110, the purpose of which is to provide a stable support base for the rotating sleeve 420. The bearing seat 410 is usually made of high-strength cast iron or cast steel to withstand the radial and axial loads transmitted by the rotating sleeve 420. The rotating sleeve 420 is rotatably disposed on the bearing seat 410 and penetrates the switching sleeve 310 of the hollow structure, and rotates relative to the switching sleeve 310, while being connected to the cam 330. The outer diameter of the sleeve is closely matched with the inner diameter of the bearing in the bearing seat 410 to ensure stability during rotation.

[0056] In actual use, the rotating sleeve 420 realizes power transmission, reduces energy loss, reduces friction between components, improves energy efficiency of the device, and reduces operating costs. The cooperation between the bearing seat 410 and the rotating sleeve 420 provides stable and precise support and transmission for the rotation of the cam 330, ensuring that the loosening operation of the loosening teeth 220 on the sintered material is more accurate and consistent, effectively improving the sintering quality.

[0057] In some examples, the telescopic sleeve 510 effectively solves the steam delivery when the position of the loosening rack 210 changes, ensures that steam can be continuously and stably supplied to the loosening teeth 220, and avoids interruption or instability of steam delivery due to the movement of the loosening rack 210, thereby ensuring the continuity and uniformity of steam spraying, which helps to improve the overall sintering effect of the sintered material. The telescopic sleeve 510 is usually made of high temperature resistant, corrosion resistant and flexible metal material. When the sintering material processing device is running, the steam is first transported to the first air hole 312 of the switching sleeve 310 through the external steam pipeline.

[0058] In actual use, since the two ends of the telescopic sleeve 510 are respectively fixed and connected to the switching sleeve 310 and the loosening rack 210, the steam enters the ventilation space 211 in the loosening rack 210 along the telescopic sleeve 510. In this process, no matter how the switching sleeve 310 rotates to adjust the position of the loosening rack 210, or the loosening rack 210 slides in the guide groove 311, the telescopic sleeve 510 can adapt to the position change of the loosening rack 210 through its own expansion and contraction, and always keep the steam delivery channel unobstructed. After the steam is evenly distributed in the ventilation space 211, it is sprayed onto the sintering material from the steam spray holes 221 on the loosening teeth 220 to achieve the humidification and combustion-supporting effects on the material.

[0059] In some examples, by rotating the sleeve 420 to control the connection between the second air hole 421 and the first air hole 312 or to cancel the connection, it is possible to determine whether steam is ejected from the steam spray hole 221, thereby achieving control over steam spraying. Unnecessary waste of steam is avoided, and the steam spray hole 221 is opened only when needed, so that steam can act more effectively on the sintering material, thereby improving the utilization efficiency of steam and reducing production costs.

[0060] In some examples, by setting the steam pipeline 610 and its third air hole 611, working in coordination with the second air hole 421 on the rotating sleeve 420 and the first air hole 312 on the switching sleeve 310, the steam can be ejected smoothly only when the three air holes are connected, which significantly improves the uniformity and stability of the sintering quality, ensures that the sintering materials can be properly treated with steam at different locations, and improves the overall sintering effect. At the same time, it also prevents steam from being ejected from other loosening racks that are not in the working position, saves the use of steam, and better controls costs.

[0061] In some examples, when the loosening teeth 220 are inserted into the material, the frustum-shaped outer sheath 710 can more effectively break the surface of the material with its own frustum-shaped energy, thereby reducing the insertion resistance. At the same time, when the outer sheath 710 moves in the material, it guides the material to disperse to both sides, so that the loosening range of the material is wider and more uniform, which helps to improve the overall air permeability of the sintered material and create better conditions for the subsequent steam penetration and combustion process. The corresponding arrangement of the connecting hole 711 on the outer sheath 710 and the steam spray hole 221 ensures the normal spray path of the steam. The frustum-shaped outer sheath 710 can guide and diffuse the sprayed steam, so that after leaving the steam spray hole 221, the steam covers the material at a more reasonable angle and range, further improving the uniformity of the steam spray, ensuring that all parts of the material can be fully humidified and combustion-supported, and improving the consistency of the sintering quality. The frustum-shaped design of the outer jacket 710 and the setting of the connecting hole 711 are optimized from two aspects, namely, material loosening and steam spraying, which significantly improves the effect of sintering material processing, makes the material loosening more uniform, and steam spraying more comprehensive, laying a solid foundation for improving the sintering quality.

[0062] In some examples, the maintenance platform 810 provides a safe, stable and easy-to-operate work area for operators to inspect and maintain the loose material teeth 220 and the outer sheath 710 above the switching sleeve 310. The maintenance platform 810 is set on the support frame 110, and the weight of the platform itself and the operator can be supported by the stable structure of the support frame 110. At the same time, the position arrangement below the switching sleeve 310 allows the operator to easily approach the loose material teeth 220 and the outer sheath 710 to perform operations such as checking the wear, replacing the outer sheath 710, and tightening the loose material teeth 220, thereby optimizing the maintenance process and improving the maintenance efficiency. The maintenance platform 810 usually adopts a metal structure to ensure that it has sufficient strength and carrying capacity. The platform table can be made of anti-slip steel plates to increase the safety of operators walking and operating on the platform. The frame part of the platform is firmly combined with the support frame 110 by welding or bolting to ensure that it will not shake or shift during use. The size of the platform is designed according to the size of the switching sleeve 310 and the space required for maintenance operations. Generally, it should ensure that the operator has enough space to carry out various maintenance operations. Through timely and effective inspection and maintenance, the good working condition of the loosening teeth 220 and the outer sleeve 710 is guaranteed, thereby improving the operating stability and reliability of the entire sintering material processing device, providing strong support for the continuous and stable production.

[0063] In some examples, a plurality of protrusions 331 arranged in sequence along the radial direction are detachably provided on the cam 330 so as to flexibly adjust the contour shape of the cam 330. By changing the number of protrusions 331 on the cam 330, the force and movement stroke when the cam 330 contacts the pushed portion 212 of the loosening rack 210 can be changed. When the number of protrusions 331 is increased, the outer contour of the cam 330 becomes more convex. During the rotation process, the displacement change generated when the cam 330 contacts the pushed portion 212 is greater, so that the loosening rack 210 obtains a larger stroke, and the loosening teeth 220 can be inserted deeper into the sintering material; conversely, reducing the number of protrusions 331 can reduce the stroke of the loosening rack 210. The loosening rack 210 has a locking screw hole 910, and the locking bolt 920 can effectively lock the loosening rack 210 to prevent it from accidentally sliding, ensuring that the loosening rack 210 that is not in the working state during the operation of the device will not move, thereby improving the stability of the device itself.
