Description

A plate feeder for sintering Technical Field

[0001] This utility model is applied in the field of sintering cleaning technology, and in particular relates to a plate feeder for sintering. Background Technology

[0002] Plate feeders are a crucial transfer equipment system commonly used in the finished product material conveying process of sintering processes.

[0003] The plate feeder is characterized by its ability to uniformly transport sintered ore from the sintering ring cooler to subsequent equipment such as belt conveyors, ensuring the stable operation of subsequent crushing, screening, and transportation processes, and avoiding idling, overload, or production interruption of subsequent equipment due to uneven feeding.

[0004] The plate feeder mainly consists of a drive unit, chain plate assembly, tensioning device, and frame. The chain plate assembly comprises grooved plates and chain links. The grooved plates are generally double-circular overlapping types, welded together from low-alloy steel plates (refer to the existing published patent: Plate Feeder, publication number: CN107499873A, publication date: 2017.12.22). Because the plate feeder has several chain plates connected and reciprocating to form a conveying link, material typically falls from the gaps between the head, tail, and middle chain plates onto the bottom of the plate feeder. Most of the sintered ore fragments generated below the plate feeder are manually cleaned, which is labor-intensive. Summary of the Invention

[0005] The purpose of this utility model is to provide a plate feeder for sintering, which solves the problem that most of the sintering ore fragments generated under the plate feeder are manually cleaned, which is labor-intensive.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This utility model provides a plate feeder for sintering, including a machine body, a transmission chain plate, a drive mechanism for rotating the transmission chain plate, and a discharge chute disposed below the discharge port of the transmission chain plate. A collection trough with an open upper end is disposed on the machine body and below the transmission chain plate. The length of the collection trough is greater than or equal to the length of the transmission chain plate. One end of the collection trough along its length is also open and extends into the discharge chute. A cleaning component is disposed in the collection trough to sweep the collected spilled material into the discharge chute.

[0008] Furthermore, the width between the two side plates in the width direction of the collection trough gradually increases from bottom to top.

[0009] Furthermore, the height of the end of the collection trough near the discharge chute from the ground is lower than the height of the other end of the collection trough from the ground.

[0010] Furthermore, the cleaning component includes a drive sprocket, a driven sprocket, a transmission motor that drives the drive sprocket to rotate, and a transmission chain connecting the drive sprocket and the driven sprocket. The drive sprocket is rotatably connected inside the discharge chute, and the driven sprocket is rotatably connected inside the end of the collection trough away from the discharge chute. Multiple scrapers are evenly arranged on one side of the transmission chain in the width direction. The bottom of the scrapers extends to the inner wall of the collection trough, and the width of the scrapers is the same as the bottom width of the collection trough.

[0011] Furthermore, the bottom of the scraper is arranged in an inverted triangle shape.

[0012] Furthermore, a limiting rod is provided along the length of the collection tank to limit the transmission chain, and the two ends of the limiting rod are rotatably connected to the side plate of the collection tank.

[0013] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0014] This utility model provides a plate feeder for sintering, including a machine body, a transmission chain plate, a drive mechanism for rotating the transmission chain plate, and a discharge chute disposed below the discharge port of the transmission chain plate. A collection trough with an open upper end is disposed on the machine body and below the transmission chain plate. The length of the collection trough is greater than or equal to the length of the transmission chain plate, and one end of the collection trough is also open and extends into the discharge chute. A cleaning component is disposed within the collection trough to sweep the collected spilled material into the discharge chute. The collection trough below the transmission chain plate collects and stores spilled sintering material, preventing it from falling onto the ground and ensuring ground cleanliness. The cleaning component automatically scrapes the sintering material from the collection trough into the discharge chute, which then transports it to the sintering conveyor belt, achieving automatic cleaning, high efficiency, improved working environment, and reduced workload for on-site personnel.

[0022] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Referring to Figures 1-4, this embodiment provides a plate feeder for sintering, including a machine body 1, a transmission chain plate 2, a drive mechanism for rotating the transmission chain plate 2, and a discharge chute 3 located below the discharge port of the transmission chain plate 2. A collection trough 4 with an open upper end is provided on the machine body 1, below the transmission chain plate 2. When material spillage occurs during the operation of the plate feeder, the fallen sintered material falls into the collection trough 4 for storage. The length of the collection trough 4 is greater than or equal to the length of the transmission chain plate 2, ensuring that all sintered material falling from the transmission chain plate 2 falls completely into the collection trough 4. One end of the collection trough 4 in the longitudinal direction is also open and extends into the discharge chute 3. The discharge chute 3 has a notch corresponding to the position of the collection trough 4, and the shape of the notch corresponds to the longitudinal section of the collection trough 4. In this case, the open end of the collection trough 4 in the longitudinal direction extends to the notch.

[0026] Referring to Figures 1-4, the width between the two side plates of the collecting tank 4 gradually increases from bottom to top. The width at the upper end between the two side plates is greater than the width of the transmission chain plate 2. This structure ensures that the sintered material falls into the collecting tank 4 and is stored in the bottom plate of the collecting tank 4. The height of the end of the collecting tank 4 near the discharge chute 3 from the ground is lower than the height of the other end of the collecting tank 4 from the ground. This inclined design facilitates the cleaning of the sintered material stored in the collecting tank 4.

[0027] Referring to Figures 1-4, a cleaning component is installed in the collection tank 4 to sweep the collected spilled material into the discharge chute 3. The cleaning component can promptly sweep the sintered material in the collection tank 4 into the discharge chute 3. The cleaning component includes a drive sprocket 5, a driven sprocket 6, a transmission motor 9 that drives the drive sprocket 5 to rotate, and a transmission chain 7 connecting the drive sprocket 5 and the driven sprocket 6. The drive sprocket 5 is rotatably connected in the discharge chute 3, and the driven sprocket 6 is rotatably connected inside the end of the collection tank 4 away from the discharge chute 3. Multiple scrapers 8 are evenly arranged on one side of the transmission chain 7 in the width direction. The bottom of the scrapers 8 extends to the inner wall of the collection tank 4, and the width of the scrapers 8 is the same as the bottom width of the collection tank 4. During operation, the drive motor 9 drives the chain and sprocket assembly. At this time, the scraper 8, which is set on the drive chain 7, moves with the drive chain 7, thereby scraping the sintered material accumulated at the bottom of the collection tank 4 into the discharge chute 3, realizing the automatic cleaning of spilled sintered material. The bottom cross-section of the scraper 8 is set in an inverted triangle shape, which facilitates the scraping of sintered material accumulated in the collection tank 4.

[0028] Referring to Figures 1-4, a limiting rod 10 is provided along the length of the collection tank 4 to limit the transmission chain 7. The limiting rod 10 is arranged in two rows, upper and lower. The upper row of limiting rods 10 supports the upper transmission chain 7, and the lower row of limiting rods 10 presses against the lower transmission chain 7, so that the transmission chain 7 is tensioned. This ensures that the bottom of the scraper 8 set on the transmission chain 7 presses better against the bottom of the collection tank 4, thereby improving the scraping quality.

[0029] In summary, the collection trough 4 set below the transmission chain plate 2 is used to collect and store the spilled sintering material. The cleaning components can automatically scrape the sintering material in the collection trough 4 into the discharge chute 3, and then transport it to the sintering conveyor belt through the discharge chute 3. This achieves automatic cleaning, which is highly efficient, improves the working environment, and reduces the workload of on-site personnel.
