Description

Technical Field

[0001] This invention relates to the field of sintering machine technology, and more specifically, to a reflector plate feeder and a sintering machine feeding system. Background Technology

[0002] Sintering is a crucial step in the iron and steel smelting process. Its main purpose is to solidify powdered iron-containing raw materials into sinter with a certain particle size and strength at high temperatures to meet the raw material requirements of blast furnace ironmaking. During sintering, the uniformity of material distribution directly affects the permeability of the material layer, heat transfer efficiency, and the final yield and quality of the sinter. Therefore, a reasonable material distribution method is of great significance for achieving efficient, stable, and high-quality sintering. Belt sintering machines, as the mainstream sintering equipment, typically consist of a shuttle distributor, a roller feeder, a reflector or multi-roller distributor, a loosening device, and a pressing device. Among these, the reflector distributor or nine-roller distributor plays a vital role—it not only distributes the sintering mixture evenly along the width of the sintering trolley but also achieves a "fine at the top, coarse at the bottom" particle size segregation distribution effect, meaning that finer particles are distributed in the upper part of the material layer, while coarser particles are deposited in the lower part. This particle size distribution is beneficial for improving the ignition surface quality, increasing the vertical sintering speed, and optimizing the distribution of airflow and temperature throughout the material layer, thereby improving the thermal efficiency and yield of the sintering process. Currently, most sintering machines in China use reflector plate feeders or multi-roller feeders for material distribution. However, long-term operation has revealed that this structure suffers from complex structure, poor reliability, and a tendency for material sticking and caking, affecting the flatness of the material distribution.

[0003] Therefore, there is an urgent need to develop a new type of reflector plate feeder for sintering machines that can significantly improve equipment operation stability, reduce failure rate and maintenance intensity while ensuring good material segregation effect, and meet the needs of modern sintering processes for efficient, intelligent and long-life equipment. Summary of the Invention

[0005] The embodiments of the present invention can be implemented as follows: An embodiment of the present invention provides a reflector fabricator, comprising: Reflector body; A cleaning component, which is movably disposed on the reflector body; A driving component is connected to the cleaning component. The driving component drives the cleaning component to reciprocate along the surface of the reflector body, so that the cleaning component cleans the material adhering to the surface of the reflector body.

[0006] Optionally, the cleaning component is a scraper, which covers the reflector body and the bottom surface of the scraper is in contact with the surface of the reflector body.

[0007] Optionally, the scraper includes a first scraper, a second scraper, and a support plate. The first scraper and the second scraper are connected and together form a wedge-shaped structure. The second scraper is attached to the surface of the reflector body. The support plate is disposed between the first scraper and the second scraper, and the edges of the opposite sides of the support plate are respectively connected to the first scraper and the second scraper.

[0008] Optionally, there are multiple support plates, which are arranged sequentially at intervals, and the length of each support plate decreases sequentially along the scraping direction of the scraper.

[0009] Optionally, the thickness of both the first scraper and the second scraper is 6mm-10mm.

[0010] Optionally, the driving component includes a first hydraulic driving component and a second hydraulic driving component, wherein the first hydraulic driving component and the second hydraulic driving component are respectively connected to both ends of the cleaning component, and are used to jointly drive the cleaning component to move along the surface of the reflector body.

[0011] Optionally, both the first hydraulic drive component and the second hydraulic drive component are hydraulic cylinders.

[0012] Optionally, the reflector plate feeder further includes a guide member disposed on the reflector plate body, and the guide member and the cleaning member are spaced apart, with a gap of 3mm-5mm between the guide member and the cleaning member.

[0013] Optionally, the guide is a guide plate, and there are two guide plates. The two guide plates are respectively disposed at both ends of the reflector body and fixedly connected to the ends of the reflector body to guide the movement direction of the cleaning component.

[0015] The beneficial effects of the reflector plate feeder and sintering machine feeding system of the present invention include, for example: The reflector plate feeder includes a reflector plate body, a cleaning component, and a driving component. The cleaning component is movably mounted on the reflector plate body. The driving component is connected to the cleaning component, and the driving component drives the cleaning component to reciprocate along the surface of the reflector plate body, thereby cleaning the material adhering to the surface of the reflector plate body. In use, by setting a reciprocating cleaning component on the reflector plate body, the sintered material adhering to the surface is dynamically removed during equipment operation, fundamentally avoiding the caking phenomenon caused by long-term material accumulation and ensuring unobstructed feeding channels. The cleaning component continuously scrapes away accumulated material on the reflector plate surface, ensuring its surface is flat and free of local blockages. This allows the sintered material to be evenly distributed along the width of the trolley, achieving an ideal particle size segregation structure of "fine at the top and coarse at the bottom." This is beneficial for improving the permeability of the material layer, increasing the vertical sintering speed and thermal energy utilization efficiency, ultimately improving the yield and quality of sintered ore.

[0026] Sintering is a crucial step in the iron and steel smelting process. Its main purpose is to solidify powdered iron-containing raw materials into sinter with a certain particle size and strength at high temperatures to meet the raw material requirements of blast furnace ironmaking. During sintering, the uniformity of material distribution directly affects the permeability of the material layer, heat transfer efficiency, and the final yield and quality of the sinter. Therefore, a reasonable material distribution method is of great significance for achieving efficient, stable, and high-quality sintering. Belt sintering machines, as the mainstream sintering equipment, typically consist of a shuttle distributor, a roller feeder, a reflector or multi-roller distributor, a loosening device, and a pressing device. Among these, the reflector distributor or nine-roller distributor plays a vital role—it not only distributes the sintering mixture evenly along the width of the sintering trolley but also achieves a "fine at the top, coarse at the bottom" particle size segregation distribution effect, meaning that finer particles are distributed in the upper part of the material layer, while coarser particles are deposited in the lower part. This particle size distribution is beneficial for improving the ignition surface quality, increasing the vertical sintering speed, and optimizing the distribution of airflow and temperature throughout the material layer, thereby improving the thermal efficiency and yield of the sintering process. Currently, most sintering machines in China use reflector plate feeders or multi-roller feeders for material distribution. However, during long-term operation, the following prominent problems have been found with this structure: 1. Complex structure and poor reliability: Traditional reflector plate feeders contain multiple mechanical transmission components (such as steel wire ropes, pulley blocks, guide rails, etc.), with a complicated overall structure and high maintenance difficulty; 2. Prone to material sticking and caking: Due to the high temperature, high humidity and easy adhesion of sintered materials, material easily accumulates on the bottom plate of the reflector and the surface of the movable plate and forms hard clumps, affecting the flatness of the fabric. 3. High risk of material clearing function failure: The moving plate may become obstructed due to corrosion or material accumulation, resulting in poor up-and-down movement. In severe cases, it may be unable to reset, causing the material clearing function to be lost. 4. The cleaning effect of the cleaning device is limited: Although a scraping device is provided, it is difficult to completely remove the hardened material, and it is also easy to get clogged or worn. 5. Frequent malfunctions affect production: Once the material cleaning mechanism fails, it will directly lead to uneven material distribution, material shortage at the edges, and reduced material layer segregation, thereby reducing the quality of sintered ore and the system's operating rate.

[0027] In summary, existing sintering machine feeders still have significant shortcomings in terms of structural design, material cleaning capability, operational reliability, and maintenance costs. In particular, there is a lack of a simple, reliable, thorough, and long-lasting solution for removing adhering materials in high-temperature and humid environments. Therefore, there is an urgent need to develop a new type of sintering machine reflector plate feeder that can significantly improve equipment operational stability, reduce failure rate and maintenance intensity while ensuring good material segregation performance, thus meeting the demands of modern sintering processes for efficient, intelligent, and long-life equipment.

[0028] Please refer to Figures 1-4 This embodiment provides a sintering machine material feeding system, which includes a reflector plate feeder. This sintering machine material feeding system effectively improves the aforementioned technical problems, effectively preventing material adhesion and accumulation, and ensuring unobstructed material feeding channels.

[0029] The reflector plate feeder includes a reflector plate body 10, a cleaning component 20, and a driving component 30. The cleaning component 20 is movably disposed on the reflector plate body 10. The driving component 30 is connected to the cleaning component 20. The driving component 30 drives the cleaning component 20 to reciprocate along the surface of the reflector plate body 10, so that the cleaning component 20 cleans the material adhering to the surface of the reflector plate body 10.

[0030] Existing reflector plate feeders suffer from the problem that, due to the high temperature, high humidity, and easy adhesion of sintered materials, material easily accumulates and hardens on the reflector plate base and movable plate surfaces, affecting the flatness of the feed. This embodiment addresses this issue by incorporating a reciprocating cleaning component 20 on the reflector plate body 10. During operation, this component dynamically removes the sintered material adhering to the surface, fundamentally preventing the hardening caused by long-term material accumulation and ensuring unobstructed feeding channels. The cleaning component 20 continuously scrapes away accumulated material from the reflector plate surface, ensuring a smooth surface without localized blockages. This allows the sintered material to be evenly distributed along the width of the trolley, achieving an ideal "fine at the top, coarse at the bottom" particle size distribution. This improves the permeability of the material layer, increases vertical sintering speed and thermal efficiency, ultimately enhancing the yield and quality of the sintered ore.

[0031] In this embodiment, compared with the original complex winch-traction movable plate structure (such as wire rope, pulley block, guide rail, etc.), the present invention adopts a design in which the driving component 30 directly drives the cleaning component 20 to reciprocate, which simplifies the overall mechanical structure, reduces the number of vulnerable parts, improves the stability and response accuracy of the system, and reduces the probability of failure.

[0032] It should be noted that the cleaning component 20 is a scraper, which covers the reflector body 10, and the bottom surface of the scraper is in contact with the surface of the reflector body 10. The scraper includes a first scraper 21, a second scraper 22, and a support plate 23. The first scraper 21 and the second scraper 22 are connected and together form a wedge-shaped structure. The second scraper 22 is in contact with the surface of the reflector body 10. The support plate 23 is disposed between the first scraper 21 and the second scraper 22, and the edges of the opposite sides of the support plate 23 are respectively connected to the first scraper 21 and the second scraper 22.

[0033] Specifically, by setting the cleaning component 20 as a scraper, and ensuring that the bottom surface of the scraper is in contact with the surface of the reflector body 10, material residues (such as dust, molten material, or other process byproducts) adhering to the reflector surface can be automatically removed during the operation of the reflector distributor or during downtime. This structure effectively prevents problems such as decreased reflection efficiency, increased thermal resistance, or localized overheating caused by material accumulation, significantly improving the cleanliness and operational stability of the reflector.

[0034] In this embodiment, the second scraper 22 is attached to the surface of the reflector body 10 to achieve the scraping function, while the first scraper 21 forms a leading edge guiding structure. This wedge-shaped structure helps guide the material to slide smoothly off the reflector surface, avoiding accumulation at the scraping front end that could cause blockage or increased resistance. The support plate 23 connects and reinforces the structure between the first scraper 21 and the second scraper 22, improving the overall mechanical strength and deformation resistance of the scraper, especially maintaining good adhesion and scraping performance under long-term heat or stress conditions. In addition, this integrated structure facilitates modular manufacturing and assembly, improving production efficiency and maintenance convenience.

[0035] Furthermore, there are multiple support plates 23, which are arranged at intervals, with the length of each support plate 23 decreasing sequentially along the scraping direction of the scraper. This arrangement of multiple spaced support plates 23 with progressively decreasing lengths along the scraping direction creates a stepped, decreasing internal support structure. This layout optimizes material distribution, reduces weight, and lowers the load requirements on the drive mechanism while ensuring the overall rigidity of the scraper. Simultaneously, the gaps between the support plates 23 facilitate heat dissipation, preventing scraper deformation or excessive temperature rise of the reflector due to localized heat accumulation. Moreover, the design of the support plates 23 decreasing in length along the scraping direction conforms to the force trend of material movement, making the front support more stable and the rear support more flexible, thereby reducing friction and wear while ensuring scraping force and extending service life.

[0036] It should also be noted that the thickness of both the first scraper 21 and the second scraper 22 is 6mm-10mm. In this embodiment, the thickness of the first scraper 21 and the second scraper 22 is 6mm. In other embodiments, the thickness of the first scraper 21 and the second scraper 22 can be 7mm, 8mm or 10mm, and no specific limitation is made here.

[0037] In this embodiment, both the first scraper 21 and the second scraper 22 are made of stainless steel. The first scraper 21 and the second scraper 22 are welded together, and the support plate 23 is welded between the first scraper 21 and the second scraper 22.

[0038] It should also be noted that the driving component 30 includes a first hydraulic driving component 31 and a second hydraulic driving component 32. The first hydraulic driving component 31 and the second hydraulic driving component 32 are respectively connected to both ends of the cleaning component 20, and are used to jointly drive the cleaning component 20 to move along the surface of the reflector body 10. By setting the driving component 30 to include the first hydraulic driving component 31 and the second hydraulic driving component 32, and respectively connecting them to both ends of the cleaning component 20, synchronous or independent drive control of both ends of the cleaning component 20 can be achieved. This dual-end drive structure effectively ensures the stability and consistency of the cleaning component 20 during its movement along the surface of the reflector body 10, avoiding uneven loading, tilting or jamming caused by unilateral force, and is especially suitable for reflector material spreaders with large lengths or complex working conditions. The hydraulic drive method has the advantages of large output force, stable operation, and strong impact resistance, and can work reliably in high temperature, heavy load or dusty environments, ensuring stable execution of cleaning actions. At the same time, the dual hydraulic drive combined with the control system can achieve precise stroke control and pressure feedback adjustment, improving the automation level and cleaning reliability of the equipment.

[0039] Specifically, the first hydraulic drive unit 31 and the second hydraulic drive unit 32 are driven separately by two control buttons to ensure the synchronization of the scraper during movement and prevent the scraper from tilting and jamming.

[0040] Specifically, the drive component 30 can be an actuator such as a hydraulic cylinder, electric push rod, or pneumatic cylinder. Combined with the control system, it can achieve automatic material removal at set times, on set distances, or as needed, without manual intervention or machine downtime for cleaning. This significantly reduces maintenance workload and improves the equipment's intelligence and operational continuity, thus achieving automated material removal and reducing labor intensity. The hydraulic cylinders are driven and controlled by two double-acting solenoid valves, and a hydraulically controlled check valve is installed on the retraction line of each hydraulic cylinder to prevent the scraper from moving downwards due to its own weight.

[0041] In this embodiment, both the first hydraulic drive component 31 and the second hydraulic drive component 32 are hydraulic cylinders.

[0042] Furthermore, the reflector plate feeder also includes a guide 40, which is disposed on the reflector plate body 10 and spaced apart from the cleaning component 20. The guide 40 is used to guide the movement direction of the cleaning component 20. Specifically, the guide 40 is a guide plate, and there are two guide plates. The two guide plates are respectively disposed at both ends of the reflector plate body 10 and welded to the ends of the reflector plate body 10 to achieve a fixed connection, thereby guiding the movement direction of the cleaning component 20.

[0043] Specifically, the gap between the guide member 40 and the cleaning member 20 is 3mm-5mm. Specifically, the gap between the guide member 40 and the cleaning member 20 is 3mm. In other embodiments, the gap between the guide member 40 and the cleaning member 20 may also be 4mm or 5mm, and no specific limitation is made here.

[0044] During operation, the scraper is positioned above the reflector body 10. The hydraulic cylinder pushes the scraper to reciprocate in a straight line along the extension direction of the reflector body 10, so that the scraper sweeps across the entire effective area of ​​the reflector body 10, pushing away or scraping off the powdery, granular, or partially molten materials adhering to the surface. Then, it returns to its original position in the reverse stroke, ready for the next cleaning cycle.

[0045] It should be noted that the "reciprocating motion" mentioned here specifically includes bidirectional linear motion along the length or width of the reflector body 10, the trajectory of which is parallel to the surface of the reflector body 10, and the range of motion covers at least the main material accumulation area.

[0046] In addition, the reflector plate feeder also includes a support tube 50 and a support rib 60. The side surface of the reflector plate body 10 away from the cleaning component 20 is connected by the support rib 60 and the support tube 50. The support rib 60 and the support tube 50 can be fixed together to form the reflector plate body 10 and adjust the tilt angle of the reflector plate body 10.

[0047] In summary, this invention provides a reflector plate feeder and a sintering machine feeding system. The reflector plate feeder includes a reflector plate body 10, a cleaning component 20, and a driving component 30. The cleaning component 20 is movably disposed on the reflector plate body 10. The driving component 30 is connected to the cleaning component 20, and the driving component 30 drives the cleaning component 20 to reciprocate along the surface of the reflector plate body 10, thereby cleaning the material adhering to the surface of the reflector plate body 10. In use, by providing the reciprocating cleaning component 20 on the reflector plate body 10, the sintering material adhering to the surface is dynamically removed during equipment operation, fundamentally avoiding the caking phenomenon caused by long-term material accumulation and ensuring the unobstructed flow of the feeding channel. The cleaning component 20 continuously scrapes away the surface material of the reflector plate to ensure that its surface is flat and free of local blockages, so that the sintering material can be evenly distributed along the width of the trolley and achieve the ideal particle size segregation structure of "fine at the top and coarse at the bottom". This is beneficial to improve the permeability of the material layer, increase the vertical sintering speed and thermal energy utilization efficiency, and ultimately improve the yield and quality of sintered ore.
