Description

Technical Field

[0001] This utility model relates to the field of sintered fabric technology, specifically to a fabric structure with an ultra-thick sintered material layer. Background Technology

[0002] Sintered ore is a primary raw material for blast furnace smelting, and its quality directly affects the stability and smooth operation of the ironmaking process and the achievement of other technical indicators. With the continuous advancement of ironmaking technology, sintered ore not only requires stable composition and high grade, but also high strength, a reasonable particle size distribution, and low powder content. Practice has proven that thick-layer sintering is one of the effective ways to save energy, reduce consumption, and improve metallurgical performance in sintering production. Thick-layer sintering is an iron ore sintering process that maintains a high material thickness (usually ≥700mm) on the sintering grate. Its core advantage lies in fully utilizing the automatic heat storage effect of the sintering process, achieving the dual goals of energy saving, consumption reduction, and quality improvement. Simultaneously, thick-layer sintering is one of the effective ways to solve problems such as low SiO2 sintering, poor strength, and high powder content. Therefore, increasing the material layer thickness can reduce sintering fuel consumption, increase sintered ore yield, and improve sintered ore quality, representing a development trend in sintering production. In sintering production, sintering material feeding is a key step that restricts the increase of material layer thickness. However, in actual use, the material often sticks to the feeding rollers when it falls on the existing sintering ultra-thick material layer feeding devices. Therefore, it is necessary to clean them to ensure that the trolley feeding can be used normally.

[0003] China Patent Network (Patent Publication No. CN211503704U) discloses a novel material feeding device for sintering ultra-thick material layers, including a trolley shell. A top plate is fixedly installed in the middle of the top of the trolley shell. Three springs are fixedly installed at the bottom of the top of the top plate. Stainless steel scrapers are fixedly installed at the bottom of the three springs. Adjustable high-powered blowers are fixedly installed on the upper parts of both sides inside the trolley shell. A material feeding roller is fixedly installed in the middle of the inside of the trolley shell. A motor is fixedly installed on the right side of the material feeding roller. A belt is sleeved on the left side of the motor.

[0004] The aforementioned fabric feeding device employs a stainless steel scraper blade welded to a top plate, connected by springs. This achieves flexible contact between the scraper blade and the fabric roller, effectively cleaning material adhering to both sides of the roller while eliminating rigid contact between the roller and the scraper, ensuring stable operation. However, because the scraper cleans the roller surface using spring pressure, long-term use can lead to spring fatigue and incomplete scraping. Furthermore, some adhered materials are highly adhesive, and flexible contact alone cannot guarantee effective removal. Utility Model Content

[0018] Embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While some embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present invention. It should be understood that the drawings and embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] This embodiment provides, for example Figure 1-6 The illustrated material distribution structure for sintering ultra-thick material layers includes a main body 1, with a transmission frame 2 fixed at one end of the main body 1 and side plates 3 attached to the outer walls of both sides of the main body 1. The main body 1 includes a main frame 101, with a top plate frame 102 fixed at the top of the main frame 101. An adjusting motor 103 is fixed at the middle of the top surface of the top plate frame 102. A rotating drum 104 is shaft-connected to the bottom end of the adjusting motor 103. A threaded shaft 105 is threadedly connected to the bottom end of the rotating drum 104. A scraper frame 106 is fixed to the bottom end of the threaded shaft 105. A scraper blade 107 is fixed to the bottom surface of the scraper frame 106. Limiting posts 108 are fixed to both ends of the scraper blade 107. Rollers 109 are shaft-connected to both sides of the bottom end of the limiting posts 108. A secondary roller 110 is attached to the bottom end of the roller 109. A connecting shaft 111 is fixed to the center of one side of the secondary roller 110, and the secondary roller 110 is fixed to both ends of the main roller body 112.

[0021] Furthermore, the main frame 101 is fixedly connected to the top plate frame 102 and the adjusting motor 103, and the rotating drum 104 forms a rotating structure with the top plate frame 102 through the adjusting motor 103; the adjusting motor 103 forms a threaded transmission structure with the threaded shaft 105 through the rotating drum 104, and the bottom end of the threaded shaft 105 is fixedly connected to the center of the top surface of the scraper frame 106; the scraper frame 106 is fixedly connected to the scraper blade 107 and the two end limit posts 108, and the bottom surface of the two end limit posts 108 is in contact with the top surface of the auxiliary roller 110 through the roller 109; the main roller body 112 forms a rotating structure with the two ends of the main frame 101 through the two end auxiliary rollers 110 and the connecting shaft 111, and the center of the top surface of the main roller body 112 is parallel and aligned with the scraper blade 107.

[0022] The fabric structure provided in the above embodiment consists of a main frame 101 supporting a main roller 112 and an auxiliary roller 110. When material adheres to the surface of the main roller 112, it can be scraped and cleaned by a scraper blade 107 with a certain gap on the top surface. In particular, the rolling contact between the limiting posts 108 at both ends of the scraper blade 107 and the auxiliary rollers 110 at both ends of the main roller 112 can prevent the scraper blade 107 from directly and rigidly contacting the surface of the main roller 112, thereby removing the adhered material while avoiding wear. At the same time, the scraper blade 107 can be raised and adjusted by the threaded shaft 105 connected to the scraper frame 106 to adapt to the processing of materials of different thicknesses.

[0023] Furthermore, when the limiting post 108 of the feeding structure provided in the above embodiment makes rolling contact with the auxiliary rollers 110 at both ends of the main roller body 112, the roller 109 can rotate synchronously with the rotation of the auxiliary rollers 110, thereby avoiding friction between the top surface of the auxiliary rollers 110 and the bottom surface of the limiting post 108 while maintaining limiting support, thus affecting the normal roller transmission.

[0024] like Figure 5As shown, the transmission frame 2 includes a transmission box 201, which is fixed to the outer wall of one end of the main frame 101. A drive shaft 202 is shaft-connected inside the transmission box 201. A drive motor 203 is shaft-connected to one side of the shaft of the drive shaft 202. A main roller body 112 is shaft-connected to the other side of the shaft of the drive shaft 202. A transmission belt 204 is attached to the outer wall of the drive shaft 202. A secondary shaft 205 is attached to both sides of the bottom end of the transmission belt 204. A side pressure roller 206 is shaft-connected to one end of the secondary shaft 205. The side pressure roller 206 and the transmission belt 204 form a transmission structure through the secondary shaft 205, and the secondary shaft 205 and the drive shaft 202 form a transmission structure through the transmission belt 204.

[0025] In order to maintain the synchronous transmission requirements of multiple sets of rollers, the fabric structure provided in the above embodiment has a transmission box 201 fixed on the outer wall of one end. The transmission box 201 can be driven by the drive motor 203 through the built-in drive shaft 202, which drives the transmission belt 204 and the side pressure roller 206 to drive synchronously, thereby ensuring that the material on both sides of the trolley is stably compacted.

[0026] like Figure 6 As shown, the side panel 3 includes a side panel frame 301, with screws 302 distributed around the perimeter of the side panel frame 301, and a blower 303 fixed to the inner wall of the side panel frame 301. The side panel frame 301 is symmetrically distributed along both sides of the main frame 101. The blowers 303 are symmetrically distributed inward along both sides of the main frame 101, and the side panel frame 301 is detachable from both sides of the main frame 101 by screws 302. The fabric structure provided in the above embodiment can blow out the scraped material through the blower 303 on the inner wall of the side plate frame 301 on both sides, keeping the material scraped off the roller surface still trapped on the surface, thus assisting in the scraping and cleaning effect.

[0027] In summary, when using the fabric structure provided in the above embodiments, the adjustment motor 103 can be adjusted according to the material scraping requirements. The adjustment motor 103 drives the connected rotating drum 104 to rotate. Then, the rotating drum 104 drives the threaded shaft 105 connected at the bottom to move downward, causing the scraper frame 106 fixed at the bottom of the threaded shaft 105 to slide downward. Then, the limiting posts 108 on both sides of the bottom of the scraper frame 106 are in contact with the top surface of the auxiliary rollers 110 at both ends of the main roller body 112 to maintain the limit. Then, the transmission frame 2 drives the main roller body 112 and the side pressure roller 206 to rotate synchronously, and the material adhering to the surface of the main roller body 112 is scraped off by the scraper blades 107 of the scraper frame 106 as it rotates.

[0028] The above description is merely a selection of preferred embodiments of this utility model and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of this utility model in the embodiments is not limited to the specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
