Abstract
Description
Technical Field
[0001] This application relates to angle steel production equipment, and more particularly to a billet surface cleaning device. Background Technology
[0002] In the iron and steel metallurgy and rolling industry, steel billets, as the core raw material for subsequent rolling production of various steel products (such as sections, plates, and pipes), directly determine the performance and quality of the final products based on their surface quality. During continuous casting, cooling, stacking, and transportation, steel billets are easily affected by high-temperature oxidation, environmental dust adhesion, and process residues, resulting in the formation of a hard oxide layer primarily composed of iron oxide (commonly known as iron scale) on their surface. Simultaneously, a large amount of iron oxide sediment, dust, oil, and other micro-debris also adheres to the billets. If these surface impurities are not thoroughly removed before rolling, they will have several adverse effects on subsequent production processes and product quality: First, during rolling, the hard iron oxide layer and impurities will come into direct contact with the roll surface, accelerating roll wear, shortening roll life, increasing equipment maintenance costs, and potentially forming indentations on the roll surface, leading to defects such as scratches and pitting on the rolled steel surface. Second, under rolling pressure, impurities may be pressed into the steel, forming internal inclusion defects, reducing the steel's mechanical properties, such as tensile strength and toughness, causing the product to fail to meet usage requirements. Third, residual iron oxide dust and particles will contaminate the lubrication system of the rolling equipment, affecting equipment operational stability, and will also spread in the production environment, posing a threat to the health of workers and the workshop environment. Therefore, efficient and thorough cleaning of the billet surface before it enters the rolling process is a crucial step in ensuring rolling quality, improving production efficiency, and reducing production costs. Summary of the Invention
[0003] In order to efficiently clean impurities on the surface of steel billets, this application provides a steel billet surface cleaning device.
[0004] The billet surface cleaning device provided in this application adopts the following technical solution: A billet surface cleaning device includes a conveyor table with a cleaning box mounted on its upper end. Rotating rollers are rotatably connected to both sides of the cleaning box, and cleaning wires are fixedly connected to the rotating rollers. A drive assembly for driving the rotating rollers is provided on the cleaning box. An upper cleaning roller for cleaning the upper surface of the billet and a lower cleaning roller for cleaning the lower surface of the billet are provided inside the cleaning box. Each of the upper and lower cleaning rollers is equipped with a steel wire rope and a fixing assembly for fixing the wire brush to the upper and lower cleaning rollers. A collection plate and a conveyor belt are provided below the cleaning box. The collection plate is fixedly connected to the conveyor belt, and a collection box is located at the tail end of the conveyor belt.
[0005] By adopting the above technical solution, the steel billet is placed on the conveyor table for transportation. At the same time, the drive assembly is activated to drive the rotating roller to rotate. Then, the two sides of the steel billet are cleaned by the cleaning wire, and the upper and lower surfaces of the steel billet are scraped by the abutting wire ropes on the upper and lower cleaning rollers. As a result, impurities such as iron oxide and dust on the steel billet fall onto the collection plate and the conveyor belt, and are then transported to the collection box for centralized collection.
[0006] Optionally, the drive assembly includes a drive motor mounted on the upper end of the cleaning box, a drive gear connected to the output shaft of the drive motor, a driven gear meshing with the drive gear, the driven gear corresponding one-to-one with the rotating roller, and the driven gear and the rotating roller being coaxially arranged and fixedly connected.
[0007] By adopting the above technical solution, the drive motor can drive the drive gear to rotate, which in turn drives the driven gear to rotate, which in turn drives the rotating roller to rotate, thereby driving the cleaning wire to clean the steel billet.
[0008] Optionally, a first pulley is fixedly connected to the driven gear, the first pulley is coaxially arranged with the driven gear, the upper cleaning roller and the lower cleaning roller are both fixedly connected to the same vertical shaft, the vertical shaft is rotatably connected to the cleaning box, a second pulley is fixedly connected to the vertical shaft, the second pulley is coaxially arranged with the vertical shaft, and the same connecting belt is sleeved between the second pulley and the first pulley.
[0009] By adopting the above technical solution, when the passive gear is driven, the vertical shaft can be rotated through the first pulley and the second pulley, thereby driving the upper cleaning roller and the lower cleaning roller to rotate.
[0010] Optionally, the fixing component includes a mounting rod, through which the upper cleaning roller and the lower cleaning roller pass and are rotatably connected. The mounting rod has multiple placement holes, in which the abutting wire rope is placed. The mounting rod is threaded with fixing bolts, which correspond one-to-one with the placement holes. The shank of the fixing bolts presses the abutting wire rope against the placement hole.
[0011] By adopting the above technical solution, the shank of the fixing bolt can be rotated to press the abutting wire rope into the placement hole, thereby fixing the abutting wire rope.
[0012] Optionally, a torsion spring is fitted onto the mounting rod, with one end of the torsion spring fixedly connected to the mounting rod and the other end of the torsion spring fixedly connected to the mounting rod.
[0013] By adopting the above technical solution, the position of the mounting rod can be limited by the torsion spring, so that the abutting wire rope is pressed tightly against the steel billet. When there are hard-to-clean debris or protrusions generated during the steel billet processing, the mounting rod can rotate to a certain extent, reducing the direct force of the steel billet protrusions on the abutting wire rope, thereby reducing the occurrence of deformation of the abutting wire rope.
[0014] Optionally, an abutment rod is fixedly connected to the mounting rod located at the lower end of the conveyor platform, and an adjusting rod for abutting the abutment rod and a cleaning plate for cleaning the abutment wire rope are fixedly connected to the conveyor platform. When the adjusting rod abuts the abutment rod, the mounting rod rotates on the upper or lower cleaning roller, and the cleaning plate abuts the abutment wire rope.
[0015] By adopting the above technical solution, the mounting rod can be rotated by the abutment rod, thereby causing impurities such as iron oxide dust that fall on the abutment rod and the abutment wire rope to fall off. At the same time, the cleaning plate combs the debris stuck on the abutment wire rope, so that the debris is detached from the abutment wire rope and falls into the conveyor belt or collection box.
[0016] Optionally, multiple upper cleaning rollers and multiple lower cleaning rollers are provided, and the upper cleaning rollers or the lower cleaning rollers are equidistant from each other around the axis of the vertical axis.
[0017] By adopting the above technical solution, multiple upper and lower cleaning rollers can be set to scrape the upper and lower surfaces of the steel billet.
[0018] Optionally, the connecting belts on both sides of the conveyor platform may have different lengths.
[0019] By adopting the above technical solution, the cleaning range of the upper and lower cleaning rollers located on different vertical axes can be increased, reducing the accumulation of impurities on the upper part of the billet.
[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. The upper and lower surfaces of the billet are scraped by the steel wire ropes on the upper and lower cleaning rollers, so that impurities such as iron oxide and dust on the billet fall onto the collection plate and conveyor belt, and are then transported to the collection box for centralized collection. 2. The drive motor can drive the drive gear to rotate, which in turn drives the driven gear to rotate, which in turn drives the rotating roller to rotate, thereby driving the cleaning wire to clean the steel billet; 3. Multiple upper and lower cleaning rollers can be used to scrape the upper and lower surfaces of the billet. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.
[0024] An embodiment of this application is: a steel billet surface cleaning device, referring to... Figure 1 and Figure 2 The system includes a conveyor platform 1, with a cleaning box 2 mounted on its upper end. The cleaning box 2 is rectangular in shape. Rotating rollers 3 are rotatably connected to both sides of the cleaning box 2. The rotating rollers 3 are located on both sides of the upper end of the conveyor belt 10, and their axes are perpendicular to the upper surface of the conveyor platform 1. Multiple cleaning wires 31 for scraping the outer surface of the steel billet are fixedly connected to the outer arc surface of the rotating rollers 3. The cleaning box 2 is equipped with a drive assembly 4 for driving the rotating rollers 3 to rotate.
[0025] Reference Figure 1 , Figure 2 and Figure 3 The drive assembly 4 includes a drive motor 41 mounted on the upper end of the cleaning box 2. A drive gear 42 is connected to the output shaft of the drive motor 41, and a driven gear 43 meshes with the drive gear 42. The driven gear 43 corresponds one-to-one with the rotating roller 3, and the driven gear 43 and the rotating roller 3 are coaxially arranged and fixedly connected. The drive motor 41 can drive the drive gear 42 to rotate, which in turn drives the driven gear 43 to rotate, which in turn drives the rotating roller 3 to rotate, thereby driving the cleaning wire 31 to clean the steel billet.
[0026] The cleaning box 2 is equipped with an upper cleaning roller 6 for cleaning the upper surface of the steel billet and a lower cleaning roller 7 for cleaning the lower surface of the steel billet. Both the upper cleaning roller 6 and the lower cleaning roller 7 are equipped with a steel wire rope 5 and a fixing component 8 for fixing the wire brush on the upper cleaning roller 6 and the lower cleaning roller 7. The fixing component 8 includes a mounting rod 81. The upper cleaning roller 6 and the lower cleaning roller 7 located on the same side of the conveyor table 1 are both fixedly connected to the same vertical shaft 18. The vertical shaft 18 is rotatably connected inside the cleaning box 2. There are multiple upper cleaning rollers 6 and lower cleaning rollers 7. The upper cleaning rollers 6 or lower cleaning rollers 7 are set at equal intervals around the axis of the vertical shaft 18.
[0027] The upper cleaning roller 6 and the lower cleaning roller 7 are threaded through and rotatably connected to the mounting rod 81. The mounting rod 81 has multiple placement holes 811. The abutting wire rope 5 is placed within each placement hole 811. A fixing bolt 82 is threaded onto the mounting rod 81, with each fixing bolt 82 corresponding to one of the placement holes 811. The shank of the fixing bolt 82 presses the abutting wire rope 5 against the placement hole 811. Thus, by rotating the fixing bolt 82, the shank of the fixing bolt 82 presses the abutting wire rope 5 against the placement hole 811, thereby fixing the abutting wire rope 5.
[0028] A first pulley 12 is fixedly connected to the driven gear 43, and the first pulley 12 is coaxially arranged with the driven gear 43. A second pulley 13 is fixedly connected to the vertical shaft 18, and the second pulley 13 is coaxially arranged with the vertical shaft 18. A connecting belt 14 is sleeved between the second pulley 13 and the first pulley 12. The lengths of the connecting belts 14 on both sides of the conveyor table 1 are different. Thus, when the driven gear 43 is driven, the first pulley 12 and the second pulley 13 can drive the vertical shaft 18 to rotate, thereby driving the upper cleaning roller 6 and the lower cleaning roller 7.
[0029] A torsion spring 15 is fitted onto the mounting rod 81 to limit its rotation. One end of the torsion spring 15 is fixedly connected to the mounting rod 81, and the other end of the torsion spring 15 is also fixedly connected to the mounting rod 81. An abutment rod 16 is fixedly connected to the mounting rod 81 located at the lower end of the conveyor table 1. An adjusting rod 17 for abutting against the abutment rod 16 and a cleaning plate 19 for cleaning the abutment wire rope 5 are fixedly connected to the conveyor table 1. When the adjusting rod 17 abuts against the abutment rod 16, the mounting rod 81 rotates on the upper cleaning roller 6 or the lower cleaning roller 7, and the cleaning plate 19 abuts against the abutment wire rope 5. Thus, the position of the mounting rod 81 can be limited by the torsion spring 15, so that the abutting wire rope 5 is pressed against the steel billet. When there are hard-to-clean debris or protrusions generated during the processing of the steel billet, the mounting rod 81 can rotate to a certain extent. At the same time, the mounting rod 81 can be rotated by the abutting rod 16, which causes impurities such as iron oxide dust that fall on the abutting rod 16 and the abutting wire rope 5 to fall off. Meanwhile, the cleaning plate 19 combs the debris stuck on the abutting wire rope 5, so that the debris is detached from the abutting wire rope 5.
[0030] The bottom of the cleaning box 2 is provided with a collection plate 9 and a conveyor belt 10. One end of the collection plate 9 is fixedly connected to the conveyor belt 10 and the end of the collection plate 9 near the conveyor belt 10 is inclined downward. The tail end of the conveyor belt 10 is provided with a collection box 11.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
