Description

Technical Field

[0001] This utility model relates to the technical field of metallurgical equipment, and in particular to a scraping device for transferring sintering materials. Background Technology

[0002] Sintered material is the raw material in the iron ore sintering process. It is usually made of fly ash and slag as the main raw materials, with a small amount of clay added. It is a lightweight aggregate obtained after high-temperature sintering, crushing and screening.

[0003] In general, steel plants use conveyor belts to transport sintered materials. Because the uneven thickness distribution of sintered materials on the conveyor belt can reduce the accuracy of subsequent moisture measurement, scrapers are installed on the conveyor belt to level the material and provide a uniform raw material layer for subsequent measurement.

[0004] Because some components in the sintered material are sticky, especially when it contains moisture or other additives, they can easily adhere to the surface of the scraper. This material adhesion makes it difficult for the scraper to level the material, reducing scraping efficiency. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and not for limiting it.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments.

[0023] Please see Figures 1 to 2 The scraping device for sintering material transfer according to this utility model includes a bracket 1, a rotating shaft 2, a scraper 3, a height adjustment component 4, and a cleaning component 5;

[0024] The bracket 1 is fixedly mounted on the conveyor belt. The rotating shaft 2 is mounted on the bracket 1 and connected to the bracket 1. The scraper 3 is fixedly mounted on the rotating shaft 2. The height adjustment component 4 is mounted on the bracket 1 and connected to the rotating shaft 2. The height adjustment component 4 is used to adjust the height of the rotating shaft 2. The cleaning component 5 is mounted on the bracket 1 and connected to the height adjustment component 4. The cleaning component 5 is connected to the rotating shaft 2 and is used to clean the surface of the scraper 3.

[0025] When the conveyor belt transports the sintered material, the scraper 3 hangs down naturally to flatten the surface of the sintered material, reducing the thickness difference of the sintered material and providing a uniform raw material layer for subsequent measurement. At the same time, the height adjustment component 4 adjusts the distance between the scraper 3 and the conveyor belt, so that the thickness of the sintered material can be adjusted according to production needs, thereby further improving the measurement and control accuracy of subsequent processes.

[0026] When too much material adheres to the scraper 3 and affects its leveling efficiency, the cleaning component 5 cleans the surface of the scraper 3, causing the material adhering to the surface of the scraper 3 to fall off, so that the scraper 3 can better level the material surface, thereby providing a more uniform raw material layer for subsequent measurements.

[0027] In this embodiment, the height adjustment component 4 includes a movable plate 41 and a cylinder 42. Two movable plates 41 are provided, and the two movable plates 41 are respectively located at both ends of the bracket 1. The movable plates 41 are slidably connected to the bracket 1. Two cylinders 42 are provided, and the two cylinders 42 correspond one-to-one with the two movable plates 41. The cylinders 42 are fixedly mounted on the bracket 1, and the piston end of the cylinder 42 is fixedly connected to the movable plate 41. The two ends of the rotating shaft 2 pass through the two movable plates 41 respectively, and the rotating shaft 2 is rotatably connected to the movable plates 41.

[0028] In this system, cylinder 42 drives moving plate 41 to move up and down relative to bracket 1, and rotating shaft 2 is rotatably mounted on moving plate 41, thereby adjusting the height of rotating shaft 2. This allows the distance between scraper 3 and conveyor belt to be adjusted according to production needs, thus improving production efficiency.

[0029] In this embodiment, the cleaning component 5 includes a cleaning part 51 and a fixing part 52. The cleaning part 51 is disposed on the bracket 1 and is used to clean the scraper 2. Two sets of fixing parts 52 are provided, and the two sets of fixing parts 52 correspond one-to-one with the two moving plates 41. The fixing parts 52 are disposed on the moving plates 41 and connected to the rotating shaft 2. The fixing parts 52 are used to keep the rotating shaft 2 in a fixed state.

[0030] When too much material adheres to the surface of the scraper 3, the worker rotates the scraper 3 to a suitable position, the fixing part 52 fixes the rotating shaft 2, so that the scraper 3 remains in a fixed state, and the cleaning part 51 cleans the surface of the scraper 3, so that the material adhering to the surface of the scraper 3 falls off, thereby cleaning the scraper 3 and improving the scraping efficiency of the scraper 3.

[0031] In this embodiment, the cleaning unit 51 includes an air tank 511, an air compressor 512, a mounting plate 513, high-pressure nozzles 514, and an air pipe 515. The air tank 511 is disposed on one side of the conveyor belt, the air compressor 512 is disposed on one side of the air tank 511 and communicates with the interior of the air tank 511, the mounting plate 513 is fixedly disposed on the bracket 1 and is located on one side of the bracket 1, and multiple high-pressure nozzles 514 are disposed evenly on the mounting plate 513, and the high-pressure nozzles 514 are communicated with the air tank 511 through the air pipe 515.

[0032] In this process, after the fixing part 52 fixes the scraper 3, high-pressure air is sprayed out from the high-pressure nozzle 514. The high-pressure air blows the surface of the scraper 3 and blows off the material adhering to the scraper 3, thereby cleaning the surface of the scraper 3. At the same time, the air compressor 512 provides a high-pressure air source to the air storage tank 511, thereby ensuring that the air storage tank 511 has sufficient high-pressure air to clean the scraper 3.

[0033] In this embodiment, the cleaning unit 51 further includes a roller brush 516 and a motor 517. The roller brush 516 is rotatably mounted on the bracket 1, and the length direction of the roller brush 516 is the same as the length direction of the scraper 3. The motor 517 is fixedly mounted on the bracket 1, and the output shaft of the motor 517 is coaxially and fixedly connected to the roller brush 516.

[0034] The motor 517 drives the roller brush 516 to rotate. The roller brush 516, in conjunction with high-pressure gas, brushes off the hardened and difficult-to-clean material adhering to the surface of the scraper 3, thereby efficiently cleaning the scraper 3 and ensuring the cleaning effect.

[0035] In this embodiment, the fixing part 52 includes a fixing block 521, a first moving block 522, a second moving block 523, a fixing bolt 524, and a spring 525. The fixing block 521 is fixedly connected to the moving plate 41. A circular groove 5211 is formed on the fixing block 521. The first moving block 522 and the second moving block 523 are both slidably disposed in the fixing block 521. The opposite sidewalls of the first moving block 522 and the second moving block 523 are both arc-shaped. The fixing bolt 524 is threaded onto the first moving block 521. 22 is threadedly connected to the second moving block 523. The spring 525 is sleeved on the fixing bolt 524 and located between the first moving block 522 and the second moving block 523. The two ends of the spring 525 are fixedly connected to the first moving block 522 and the second moving block 523 respectively. The rotating shaft 2 passes through the circular groove 5211 and abuts against the side wall of the circular groove 511. The rotating shaft 2 abuts against the arc-shaped side wall of the first moving block 522 and the arc-shaped side wall of the second moving block 523.

[0036] In this configuration, the side wall of the rotating shaft 2 abuts against the side wall of the circular groove 5211. When the fixing bolt 524 is turned, the fixing bolt 524 drives the first moving block 522 and the second moving block 523 to move towards each other. The spring 525 is compressed and accumulates elastic force. The arc-shaped side walls of the first moving block 522 and the second moving block 523 abut tightly against the side wall of the rotating shaft 2, thereby fixing the rotating shaft 2.

[0037] When it is necessary to rotate the shaft 2, the fixing bolt 524 is turned in the opposite direction. The first moving block 522 and the second moving block 523 move away from each other under the action of the spring force of the spring 525, so that the shaft 2 can rotate.

[0038] In this embodiment, the support 1 is provided with a connecting rod 6, a fixed shaft 7, and a second scraper 8. There are two connecting rods 6, which are respectively fixedly installed at both ends of the support 1 and located on one side of the support 1. The fixed shaft 7 is located at the end of the connecting rod 6 away from the support 1 and is fixedly connected to both connecting rods 6. The second scraper 8 is fixedly installed on the fixed shaft 7, and the side of the second scraper 8 away from the fixed shaft 7 abuts against the conveyor belt.

[0039] When conveying sintered materials, some residues or dust often remain on the surface of the conveyor belt. The second scraper 8 comes into contact with the conveyor belt. When the conveyor belt is running, the second scraper 8 scrapes off the material remaining on the surface of the conveyor belt, protecting the conveyor belt and extending its service life.

[0040] In this embodiment, a collection box 9 is provided below the second scraper 8, and the collection box 9 is connected to the conveyor belt.

[0041] The collection box 9 collects the material scraped off the conveyor belt by the second scraper 8, thus avoiding material waste and improving the production environment.

[0042] This scraping device for sintering material transfer includes a support 1, a rotating shaft 2, a scraper 3, a height adjustment component 4, and a cleaning component 5. The support 1 is fixedly mounted on the conveyor belt, the rotating shaft 2 is mounted on and connected to the support 1, the scraper 3 is fixedly mounted on the rotating shaft 2, the height adjustment component 4 is mounted on the support 1 and connected to the rotating shaft 2, and the height adjustment component 4 is used to adjust the height of the rotating shaft 2. The cleaning component 5 is mounted on the support 1 and connected to the height adjustment component 4, and the cleaning component 5 is connected to the rotating shaft 2 and is used to clean the surface of the scraper 3. This scraping device for sintering material transfer achieves the removal of material adhering to the surface of the scraper 3 through the arrangement of various structures, so that the scraper 3 can better scrape the material surface, providing a more uniform raw material layer for subsequent measurement, thereby ensuring production quality.
