Description

Technical Field

[0001] This invention relates to the field of sintering machine technology, and more specifically, to a belt sintering machine for preventing material blockage. Background Technology

[0002] Belt sintering machines are core equipment in the sintering production of the iron and steel metallurgical industry. They are mainly used to process iron ore powder, fuel, and auxiliary materials into block sinter, providing qualified raw materials for subsequent blast furnace ironmaking processes. Belt sintering machines have the advantages of continuous and large-scale production. Their operational stability and material distribution uniformity directly determine the quality of the finished sinter, sintering production efficiency, and equipment energy consumption. Therefore, they are widely used in major iron and steel sintering production lines.

[0003] The core production process of a belt sintering machine includes four major steps: material feeding, ignition, sintering with exhaust gas, and unloading at the tail end. Among these, the material feeding step is a crucial preliminary step to ensure the sintering effect. During production, the sintering mixture after mixing and granulation is fed from the hopper by a roller feeder, and then the particle size distribution is completed by a nine-roller distributor arranged at an incline. This ensures that the mixture is evenly spread on the sintering trolley grate, forming an ideal material layer structure with coarser material at the bottom and finer material at the top. This optimizes the permeability of the material layer and ensures the stable operation of the subsequent sintering with exhaust gas process.

[0004] Currently, the mainstream material feeding method in the industry adopts a combination structure of a circular roller feeder and a fixed nine-roller feeder. This method relies on multiple parallel feeding rollers with pre-set fixed gaps to achieve material screening and stratified feeding. During operation, the mixture rolls downwards along the inclined feed roller surfaces. Small-diameter powder particles are screened off through the roller gaps, while larger-diameter particles slide along the roller surface to the end and fall. The continuous movement of the trolley creates particle size segregation in the feeding process, thus meeting the feeding process requirements of sintering production and adapting to continuous feeding operations for conventional sintering materials.

[0005] However, due to the need to add a certain amount of water during the production and preparation of sintering mixtures to ensure granulation effect, the mixtures have a certain degree of viscosity. During long-term continuous feeding operations, as the mixtures continuously roll and flow along the surface of the feeding rollers, some damp fine powders are very easy to adhere to the outer wall of the feeding rollers. As production time accumulates, the adhesive layer on the roller wall will gradually and slowly thicken, squeezing the inherent screening gap between adjacent rollers. When small-diameter powders fall from the roller gaps, they are easy to get stuck at the narrowing roller gap position. The blockage of the roller gap will directly increase the rotational resistance of the feeding rollers, causing a sudden increase in the load on the feeding roller drive motor, resulting in stalling and stopping, and interrupting the feeding process.

[0006] Therefore, there is an urgent need for a belt sintering machine that prevents material blockage to solve the above problems. Summary of the Invention

[0007] This invention provides a belt sintering machine for preventing material blockage. It adds a collection trough with a cleaning component and a scraping component below the feeder roller. The scraping component, positioned upstream along the roller's rotation direction and with a gap between it and the roller wall, first coarsely scrapes away any excessively thick adhesive layers. Then, the cleaning component, elastically pressing against the roller wall downstream, brushes away all thin layers and residual adhesive material after the coarse scraping. The detached material is collected and recycled in the collection trough, preventing powder from continuously accumulating and crowding the roller gaps, and preventing fine particles from getting stuck and compacting into clumps. This solves the problems mentioned in the background art, namely:

[0008] The sintering mixture has a certain degree of stickiness. After a long period of time, the fine powder adheres to the outer wall of the feeding roller, thickens and squeezes the roller gap. Small particles get stuck in the roller gap, causing the roller to jam. This leads to increased resistance to the rotation of the feeding roller, stalling of the drive motor, and interruption of the feeding process.

[0009] To achieve the above objectives, the anti-clogging belt sintering machine includes a trolley track and a hopper. The trolley track is equipped with a sintering trolley and a material distributor. The material distributor is located above the sintering trolley, and a roller feeder is located below the hopper. The material falls from the hopper, passes through the roller feeder, and enters the material distributor. The material distributor then layers the particles of different sizes onto the sintering trolley.

[0010] The fabric feeder includes a support frame with two side frames and multiple rollers between the two side frames. The multiple rollers rotate clockwise. A collection trough is provided below each roller. A cleaning component and a scraping component are provided inside the collection trough. Along the rotation direction of the rollers, the scraping component is located upstream of the cleaning component. The cleaning component is pressed against the outer wall of the roller under the action of elastic force. A gap is left between the scraping component and the outer wall of the roller.

[0011] The scraping assembly is configured to intercept, scrape, and loosen adhesive material on the outer wall of the roller that is thicker than the gap between itself and the outer wall of the roller when the roller rotates. The cleaning assembly is configured to elastically press against the outer wall of the roller when the roller rotates, and to brush and remove thin layers of adhesive material that have not come into contact with the scraping assembly, as well as the adhesive material remaining after being scraped and loosened by the scraping assembly. The collection trough is configured to receive the material that has been removed from the roller by the cleaning assembly and the scraping assembly.

[0012] In the above technical solution, because the scraping component is set on the upstream side of the cleaning component along the rotation direction of the roller, and a gap is reserved between the scraping component and the outer wall of the roller, and the cleaning component is elastically attached to the roller wall, and a collection trough that can receive the falling material is provided below the roller, during the clockwise rotation of the roller, the stubborn and initially compacted wet powder on the roller wall is first scraped and loosened by the intermittent scraping component, and then the loose fine powder remaining on the roller wall is thoroughly brushed and cleaned by the elastically attached cleaning component.

[0013] Based on this, the collecting trough is located below the roller, and the width of the collecting trough along the axial direction of the roller is smaller than the diameter of the roller.

[0014] Furthermore, each of the two opposing sides of the frame is provided with multiple slots, and the two ends of the collection slot are movably engaged with the slots through a snap-fit ​​assembly, thereby achieving a detachable connection between the collection slot and the frame.

[0015] In this technical solution, the buckle assembly includes a protruding rod, which is telescopically disposed at the end of the collection groove. One end of the protruding rod is connected to the inside of the collection groove by a first spring, and the other end of the protruding rod is arc-shaped. The inner wall of the buckle groove is provided with a groove that matches the arc-shaped end of the protruding rod. The arc-shaped end of the protruding rod is engaged in the groove under the elastic force of the first spring.

[0016] In addition, the cleaning assembly includes a support groove fixedly connected inside the collection tank. The support groove extends along the length of the collection tank. Multiple support rods are slidably connected inside the support groove. Brush bristles are fixedly connected to the top of the support rods. A second spring is connected between the bottom of the support rods and the support groove. Under the elastic force of the second spring, the support rods push the brush bristles against the outer wall of the roller.

[0017] Preferably, the bristles are made of stiff, short bristles and are used to brush the adhesive material on the outer wall of the roller when the roller rotates, so as to break the adhesion layer between the adhesive material and the outer wall of the roller.

[0018] In another technical solution, the scraping assembly includes multiple blades arranged in parallel, which are rotatably connected by a rotating rod. The rotating rod is fixedly connected inside the collecting trough, and one end of each blade is adjacent to the outer wall of the roller, with a gap between the blade and the outer wall of the roller.

[0019] Preferably, the blade has an arc-shaped structure at one end near the roller that bends in the opposite direction to the rotation direction of the roller, for guiding the scraped adhesive material into the collection tank; the blade is made of wear-resistant alloy material.

[0020] Meanwhile, each blade is provided with a rotary spring between itself and the rotating rod. The rotary spring is used to apply an elastic bias force to the blade so that the blade remains in the working position without external force. When the load on the blade exceeds a preset threshold, the blade overcomes the elastic force of the rotary spring and deflects around the rotating rod to avoid resistance. After the load is removed, the rotary spring drives the blade to reset.

[0021] Furthermore, the scraping assembly also includes a baffle fixedly connected to the inner wall of the collection tank. Along the rotation direction of the roller, the baffle is located upstream of the blade, and one outer wall of the blade is attached to the baffle. The baffle is used to limit the deflection stroke of the blade under the action of the rotary spring.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. By setting a collection trough below the roller and configuring a cleaning component and a scraping component inside the collection trough, the scraping component located upstream along the roller rotation direction first engages with the outer wall of the roller, and the cleaning component located downstream presses against the outer wall of the roller under the action of elastic force.

[0024] As the rollers continue to rotate clockwise, a graded cleaning process is formed based on the thickness of the adhesive layer: for thick layers of adhesive that exceed the scraping gap, the scraping component first performs coarse scraping to loosen them; for thin layers that do not reach the scraping component and for the material remaining after coarse scraping, the cleaning component then performs elastic close-fitting brushing. The two complement each other to ensure that the roller wall is thoroughly cleaned.

[0025] 2. By leaving a gap between the scraping assembly and the outer wall of the roller, the scraping assembly does not need to directly contact the outer wall of the roller when scraping off the material adhering to the roller wall. This allows for targeted scraping and loosening of the initially compacted adhesive material on the roller surface without scratching the outer wall of the roller. At the same time, this gap allows a small amount of residual fine powder to pass through, which is convenient for the downstream cleaning assembly to perform secondary brushing. This creates a progressive cleaning relationship between the scraping assembly and the cleaning assembly. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Currently, the sintering mixture is prone to sticking to the roller wall due to its inherent stickiness, and long-term material accumulation can cause the roller gaps to become clumped and the particles to jam, ultimately leading to roller jamming, motor stalling, and interruption of the material feeding operation. This invention provides a belt sintering machine with anti-clogging properties. See [link to relevant documentation]. Figures 1-2 As shown, the system includes a trolley track 1 and a hopper 12. A sintering trolley 11 and a material distributor 2 are mounted on the trolley track 1. The material distributor 2 is located above the sintering trolley 11, and a roller feeder 13 is located below the hopper 12. During operation, material falls from the hopper 12, is metered out by the roller feeder 13, and then falls into the material distributor 2. The material distributor 2 segregates and stratifies the particles of different sizes in the mixture, ensuring that materials of different particle sizes are laid proportionally on the circulating sintering trolley 11, forming a material layer structure with a coarser bottom and a finer top. This provides a material layer foundation with good air permeability for the subsequent exhaust sintering process.

[0044] See Figure 3 and Figure 4 As shown, the fabric feeder 2 includes a bracket 21 fixedly connected to the trolley track 1. The bracket 21 is provided with two side frames 22. Multiple rollers 23 that can rotate in the same direction are arranged in parallel between the two side frames 22. The multiple rollers 23 rotate uniformly in the clockwise direction during operation.

[0045] Figure 5In this process, a collection trough 24 is provided below the roller 23. The collection trough 24 is located directly below the roller 23, and the width of the collection trough 24 along the axial direction of the roller 23 is designed to be smaller than the diameter of the roller 23. This ensures that the collection trough 24 only covers the cylindrical area of ​​the roller 23 and does not extend below the gap between adjacent rollers 23. This avoids the collection trough 24 interfering with the normal screening of materials from the roller gap, and ensures that small-diameter particles can still fall from the roller gap to the trolley material layer along the original path.

[0046] Each of the two frame sides 22 has multiple slots on opposite sides. The two ends of the collection slot 24 are respectively engaged with the corresponding slots on the frame side 22 via snap-fit ​​components 25, thus forming a detachable connection between the collection slot 24 and the frame side 22. Specifically, see... Figure 6 As shown, the buckle assembly 25 includes a protruding rod 250, which is telescopically disposed at the end of the collection groove 24. One end of the protruding rod 250 extends into the collection groove 24 and is connected to the inner wall of the collection groove 24 through a spring 251. The other end of the protruding rod 250 extends outward and has an arc-shaped end. The inner wall of the buckle groove is provided with a groove that matches the shape of the arc end of the protruding rod 250.

[0047] During assembly, the arc-shaped end of the protruding rod 250 automatically engages with the groove under the elastic force of the first spring 251, enabling the quick installation and fixation of the collection trough 24. During disassembly, simply pull the collection trough 24 outward, and the arc-shaped end of the protruding rod 250 will slide out along the arc surface of the groove, releasing the locking mechanism and facilitating the periodic cleaning of accumulated material inside the collection trough 24.

[0048] Additionally, see Figure 7 As shown, the collection tank 24 is also equipped with a cleaning component 26 and a scraping component 27. When viewed along the clockwise rotation direction of the roller 23, the scraping component 27 is arranged on the upstream side of the cleaning component 26. That is, any point on the outer wall of the roller 23 will first pass the position of the scraping component 27 during the rotation, and then pass the position of the cleaning component 26. The cleaning component 26 is kept pressed against the outer wall of the roller 23 under the action of elastic force, while a set gap is reserved between the scraping component 27 and the outer wall of the roller 23.

[0049] Specifically, such as Figure 8As shown, the cleaning assembly 26 includes a support groove 260 fixedly connected inside the collection groove 24. The support groove 260 extends along the length of the collection groove 24 and its length is adapted to the internal width of the collection groove 24. Multiple support rods 261 are slidably connected inside the support groove 260. Each support rod 261 is independently arranged at equal intervals along the length of the support groove 260. A brush bristle 262 is fixedly connected to the top of each support rod 261. A second spring 263 is connected between the bottom of the support rod 261 and the bottom of the support groove 260. Under the elastic force of the second spring 263, each support rod 261 is pushed upward independently, thereby pushing the brush bristle 262 to always press against the outer wall of the roller 23.

[0050] Figure 10 In this design, multiple support rods 261 are independently floating, allowing each bristle 262 to adapt to the slight deformation or differences in the thickness of the adhesive layer in different sections of the outer wall of the roller 23, ensuring that the bristles 262 and the roller wall maintain a continuous and uniform adhesion pressure. The bristles 262 are made of stiff short bristles. When the roller 23 rotates clockwise, the bristles 262 continuously brush the adhesive material on the outer wall of the roller 23 under the action of elasticity. Through physical scraping, the adhesion layer between the wet powder and the metal outer wall of the roller 23 is broken, causing the adhesive material to peel off from the roller wall surface.

[0051] See Figure 9 As shown, the scraping assembly 27 includes a plurality of blades 270 arranged in parallel. Each blade 270 is arranged in parallel along the axial direction of the roller 23 and is spaced apart from each other by a set distance. The plurality of blades 270 are rotatably connected by the same rotating rod 271, which is fixedly connected to the inside of the collection tank 24.

[0052] Figure 10 In this process, one end of the blade 270 is adjacent to the outer wall of the roller 23 and a preset gap is left between them; and during the clockwise rotation of the roller 23, the scraping assembly 27 is located upstream of the cleaning assembly 26. Therefore, the material adhering to the outer wall of the roller 23 first passes through the station where the scraping assembly 27 is located: since there is a gap between the scraping assembly 27 and the roller wall, the gap allows the roller wall adhesive layer of normal thickness to pass through, but it forms a scraping and loosening effect on the local adhesive layer that has reached a certain thickness, and destroys and loosens the initially compacted adhesive material on the roller wall at specific points; then the roller wall continues to rotate to the station where the cleaning assembly 26 is located, and the bristles 262 perform a secondary brushing of the loose fine powder that remains on the roller wall after being loosened by the scraping assembly 27, so that the residual material is removed from the roller wall.

[0053] In addition, such as Figure 10As shown, the blade 270 has an arc-shaped structure that bends in the opposite direction to the rotation direction of the roller 23 at one end near the roller 23. The bending direction of the arc-shaped structure is opposite to the rotation direction of the roller 23, so that the adhesive material scraped by the blade 270 can smoothly slide down along the surface of the arc-shaped end and be guided into the collection groove 24, avoiding the accumulation of material at the end of the blade 270. At the same time, the blade 270 is made of wear-resistant alloy material to extend the service life of the blade 270 under long-term scraping conditions.

[0054] In the above technical solution, each blade 270 is independently equipped with a rotary spring (not shown in the figure) between it and the rotating rod 271. The rotary spring continuously applies an elastic bias force to the blade 270, so that the blade 270 remains in a preset working position and angle when no external force is applied. When the blade 270 encounters large hard particles that are difficult to scrape off or compacted hard lumps during operation, causing the working load to exceed the preset threshold, the blade 270 can overcome the elastic force of the rotary spring and make an adaptive deflection around the rotating rod 271 to avoid the resistance, thereby avoiding the bending or breakage of the blade 270 due to rigid obstruction. After the resistance passes, the load is eliminated, and the elastic force of the rotary spring drives the blade 270 to automatically return to the working position.

[0055] In addition, the scraping assembly 27 also includes a baffle fixedly connected to the inner wall of the collection trough 24, viewed along the rotation direction of the roller 23. Figure 10 In this process, the baffle is located on the upstream side of the blade 270. One side of the outer wall of the blade 270 is attached to the surface of the baffle in the working state. This is used to limit the limit stroke of the blade 270 when it deflects in the working direction under the action of the rotary spring. This ensures that the blade 270 can return to the same working angle after each reset, and keeps the gap between the end of the blade 270 and the outer wall of the roller 23 constant. This ensures that the scraping effect of the scraping assembly 27 on the material adhering to the roller wall is stable in the long term.

[0056] It should be noted that the multiple support rods 261 and multiple blades 270 are all set as multi-segment independent structures arranged along the axial direction of the roller 23, so that each working unit of the cleaning assembly 26 and the scraping assembly 27 has the ability to independently adapt and adjust, independently overload protection and independently repair and replace.

[0057] For the cleaning assembly 26, each support rod 261 is floated and supported by an independent No. 2 spring 263, so that each bristle 262 can adapt to the slight deformation, processing tolerance and local uneven wear of different sections of the outer wall of the roller 23, ensuring that the bristles 262 can maintain uniform and continuous contact pressure with the roller wall throughout the width of the roller 23; at the same time, when individual support rods 261 are accidentally stuck or the bristles 262 are excessively worn, the remaining support rods 261 can still work normally, the cleaning function will not be completely lost, and during maintenance, only the individual support rods 261 that have failed need to be replaced, without replacing all the bristles 262;

[0058] For the scraping assembly 27, each blade 270 is connected to the rotating rod 271 via an independent rotary spring. When there are hard particles or compacted hard lumps in the roller surface area corresponding to a certain blade 270, causing the working load to exceed the preset threshold, the blade 270 can independently overcome the elastic force of its own rotary spring and deflect around the rotating rod 271 to avoid resistance, while the adjacent blades 270 are unaffected and continue to perform normal scraping operations, thereby avoiding damage to the entire set of blades 270 or interruption of the fabric application due to local jamming. After the resistance passes, the blade 270 automatically returns to the working angle limited by the baffle under the action of the rotary spring, ensuring that the scraping gap between the end of each blade 270 and the outer wall of the roller 23 remains consistent over a long period of time.

[0059] Therefore, the multi-segment independent structure enables the cleaning component 26 and the scraping component 27 to not only perform the functions of brushing and scraping respectively, but also to have the fault tolerance and self-adaptation capabilities to cope with local abnormal working conditions on the roller surface, reducing the maintenance difficulty and spare parts cost of the equipment, and ensuring the stability and reliability of the material distributor 2 in long-term continuous operation.

[0060] Working principle:

[0061] During use, the mixture falls through the hopper 12 and is quantitatively discharged by the roller feeder 13. After entering the distributor 2, it rolls downward along the surface of multiple clockwise rotating rollers 23. During this process, because the sintering mixture itself contains a certain amount of moisture and the fine powder is sticky, some of the damp powder will continue to adhere to the outer wall of the rollers 23 and rotate with the rollers 23. As the rollers 23 continue to rotate, the material adhering to their outer wall first passes through the station where the scraper assembly 27 is located. A set gap is reserved between the scraper assembly 27 and the outer wall of the rollers 23, which allows the roller wall adhesion layer of normal thickness to pass through.

[0062] For localized layers of adhesive material that have reached a certain thickness, the scraping component 27 scrapes and loosens them at specific points, breaking down and loosening the initially compacted adhesive material on the roller wall. Subsequently, the roller 23 continues to rotate, and the loose fine powder remaining on the outer wall after being loosened by the scraping component 27 enters the station of the cleaning component 26. Under the action of elastic force, the cleaning component 26 always remains pressed against the outer wall of the roller 23, and the residual material is peeled off from the roller wall surface by the continuous brushing action of the bristles 262, thus breaking the adhesion layer between the wet powder and the metal outer wall of the roller 23.

[0063] At this time, the material that has been removed from the outer wall of the roller 23 after being cleaned by the scraping component 27 and the cleaning component 26 in succession falls into the collection trough 24 below the roller 23 under the action of gravity, and is collected and recycled by the collection trough 24, thereby completing the complete removal of the material adhering to the outer wall of the roller 23.

[0064] In the above process, along the clockwise rotation direction of the roller 23, the scraping assembly 27 is arranged upstream of the cleaning assembly 26, so that any point on the outer wall of the roller 23 passes through the scraping assembly 27 first and then the cleaning assembly 26 during the rotation. The two sequentially apply scraping and brushing actions to the same roller surface area, forming a progressive cleaning relationship. The scraping assembly 27 first performs coarse scraping and loosening, destroying the initially compacted sticky layer and reducing the workload of the subsequent cleaning assembly 26. The cleaning assembly 26 then performs fine cleaning, completely removing the loose fine powder that remains after loosening.

[0065] At the same time, the width of the collecting trough 24 along the axial direction of the roller 23 is smaller than the diameter of the roller 23, so that the collecting trough 24 only covers the cylindrical area of ​​the roller 23 and does not extend to the gap between adjacent rollers 23. This ensures that small-diameter particles can still fall normally from the roller gap to the trolley material layer along the original path, and will not interfere with the original segregation feeding function of the feeder 2 due to the addition of the collecting trough 24.

[0066] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.

The belt sintering machine for anti-clogging material according to claim 5, characterized in that: The bristles (262) are made of stiff, short bristles and are used to brush the adhesive material on the outer wall of the roller (23) when the roller (23) rotates, so as to break the adhesion layer between the adhesive material and the outer wall of the roller (23).

7. The belt sintering machine for anti-clogging material according to claim 1, characterized in that: The scraping assembly (27) includes a plurality of blades (270) arranged in parallel. The plurality of blades (270) are rotatably connected by a rotating rod (271). The rotating rod (271) is fixedly connected inside the collection trough (24). One end of the blade (270) is adjacent to the outer wall of the roller (23) and a gap is left between it and the outer wall of the roller (23).

8. The belt sintering machine for anti-clogging material according to claim 7, characterized in that: The blade (270) has an arc-shaped structure that bends in the opposite direction to the rotation direction of the roller (23) at one end near the roller (23) to guide the scraped adhesive material into the collection tank (24); the blade (270) is made of wear-resistant alloy material.

9. The belt sintering machine for anti-clogging material according to claim 7, characterized in that: Each blade (270) is provided with a rotary spring between it and the rotating rod (271). The rotary spring is used to apply an elastic bias force to the blade (270) so that the blade (270) is kept in the working position without external force. When the load on the blade (270) exceeds a preset threshold, the blade (270) overcomes the elastic force of the rotary spring and deflects around the rotating rod (271) to avoid resistance. After the load is removed, the rotary spring drives the blade (270) to reset.

10. The belt sintering machine for anti-clogging material according to claim 7, characterized in that: The scraping assembly (27) also includes a baffle (272) fixedly connected to the inner wall of the collection trough (24). Along the rotation direction of the roller (23), the baffle (272) is located upstream of the blade (270). One outer wall of the blade (270) is attached to the baffle (272). The baffle (272) is used to limit the deflection stroke of the blade (270) under the action of the rotary spring.
