Description

Technical Field

[0001] This utility model belongs to the field of conveying equipment technology, and relates to a novel steel material conveying line. Background Technology

[0002] As an indispensable raw material in the steelmaking process, scrap steel has become increasingly important in recent years due to continuous technological advancements in the global steel industry and growing environmental awareness. In particular, driven by short-process electric arc furnace steelmaking and high-scrap-ratio converter steelmaking technologies, the utilization rate of scrap steel has significantly increased, becoming a crucial way for steel companies to reduce costs, improve resource utilization efficiency, and minimize environmental pollution.

[0003] However, the upstream stage of scrap steel utilization, namely the recycling and processing of scrap steel, still faces numerous challenges. Currently, the technology for scrap steel recycling and processing is relatively backward, with low levels of mechanization and automation, resulting in high overall costs and significant safety risks and environmental pressures. These factors severely restrict the high-quality development of the scrap steel industry and limit the effective utilization of scrap steel resources.

[0004] Specifically, scrap steel is characterized by its complex block size, sharp edges, high abrasiveness, and impact properties. These characteristics place extremely high demands on conveying equipment during transport. Traditional belt conveyors, due to limitations in belt material and structure, are unable to withstand the wear and impact of scrap steel, resulting in short conveyor belt lifespan, high maintenance costs, and even potential safety accidents.

[0005] Currently, the transportation of scrap steel mostly relies on road transport. While this method is flexible, it suffers from low logistics efficiency and high transportation costs. Furthermore, road transport presents certain safety hazards, such as vehicle overloading and speeding, which can threaten environmental and personnel safety.

[0006] Therefore, developing a high-efficiency, safe, and economical conveying equipment that can adapt to the characteristics of scrap steel has become an urgent problem to be solved in the scrap steel recycling and processing industry. This equipment needs to have high wear resistance and tear resistance to withstand the impact and abrasion of scrap steel, while also possessing good replaceability so that the conveyor belt can be quickly replaced when damaged, reducing maintenance costs. Utility Model Content

[0007] In view of this, the purpose of this utility model is to provide a new type of steel conveying line to solve the problem of scrap steel transportation in the prior art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a novel steel material conveying line, comprising a head assembly, a tail assembly and tensioning assembly, a surface-enlarging wheel, and a frame. The frame is equipped with an upper idler roller, a lower idler roller, a vertical roller, a baffle assembly, and a buffer chute. The upper and lower idler rollers are provided with special conveyor belts for transporting materials. The special conveyor belts bypass the head assembly, the tail assembly and tensioning assembly, and the surface-enlarging wheel to realize the conveying of steel materials.

[0009] Optionally, the special conveyor belt includes a base belt and replaceable short belts, which are sequentially and tightly installed on the base belt and cover the entire base belt, and are in direct contact with the conveyed material.

[0010] Optionally, the replaceable short strap consists of a short strap and a connecting assembly, wherein the short strap is detachably fixed to the base strap via the connecting assembly.

[0011] Optionally, the lower support roller includes a lower support roller frame and a lower support roller mounted thereon, the lower support roller frame being fixed to the frame and used to mount the vertical roller.

[0012] Optionally, the lower idler roller may have one or more lower idler rollers, with the multiple lower idler rollers distributed on both sides and in the middle of the special conveyor belt, or a single lower idler roller may be installed in the middle of the special conveyor belt.

[0013] Optionally, the face-enlarging wheel includes a face-enlarging wheel frame and a face-enlarging wheel body. The face-enlarging wheel frame is composed of a mounting base and a mounting shaft and is fixed to the machine frame. The face-enlarging wheel body is mounted on the mounting shaft.

[0014] Optionally, the surface-enlarging wheel body is provided with one or more wheel bodies, with multiple wheel bodies evenly distributed on the mounting shaft, or a single wheel body installed in the middle position of the mounting shaft.

[0015] Optionally, the baffle assembly consists of two side enclosures, mounting brackets, and small blocks. The two side enclosures are fixed to the frame by the mounting brackets, and the small blocks, together with the two side enclosures and the special conveyor belt, form a material conveying area.

[0016] Optionally, the buffer chute is an arc-shaped structure with successively decreasing angles or a multi-stage chute, used to mitigate material impact.

[0017] Optionally, the vertical roller is installed on the carrying section and return section of the special conveyor belt, and is set between two sets of idlers or directly installed on the idler frame for conveyor belt correction.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1) Improved wear resistance and tear resistance: This invention uses a special conveyor belt to replace the traditional conveyor belt. This special conveyor belt includes a base belt and replaceable short belts, which significantly improves the wear resistance and tear resistance of the conveyor belt. This design allows the conveyor belt to better withstand the conveying of materials with sharp edges, high abrasiveness, and impact characteristics, such as scrap steel, thus extending the service life of the conveyor belt.

[0020] 2) Enhanced replaceability and reduced maintenance costs: The replaceable short belt design in the special conveyor belt allows for quick and easy replacement when a short belt needs to be replaced due to wear or partial puncture, without having to replace the entire conveyor belt. This design reduces maintenance costs and improves equipment availability and production efficiency.

[0021] 3) Achieving continuous and efficient conveying: By using a special conveyor belt driven by a combination of head sections, steel is transported from the tail section to the buffer chute at the head section, and then falls onto the downstream conveyor line, achieving continuous conveying of steel. This conveying method improves logistics efficiency, reduces transportation costs, and has significant advantages over traditional road transport methods.

[0022] 4) Ensuring worker safety: This invention uses an automated conveying system to transport materials, minimizing human intervention during the process and thus ensuring worker safety. This design reduces the risk of accidents and improves workplace safety.

[0023] 5) Optimize the conveyor structure and improve transmission efficiency: The design of the surface-enhancing rollers increases the transmission wrap angle, thereby improving transmission efficiency. Simultaneously, the rational layout of the lower idler rollers and vertical rollers ensures that the conveyor belt receives uniform support and correction in both the carrying and return sections, guaranteeing the stability and reliability of the conveying process.

[0024] 6) Reduce material impact and extend equipment life: The buffer chute is designed as an arc-shaped or multi-stage chute with angles gradually decreasing from large to small. This reduces the angle at which material cuts into the downstream conveyor line at the transfer point, thereby mitigating the impact of the material. This design extends the service life of the equipment and reduces the frequency of equipment maintenance and replacement.

[0025] 7) High adaptability and wide range of applications: This novel steel conveying line is not only suitable for conveying scrap steel, but also for conveying other materials with similar characteristics. Its flexible design and optimized structure enable the equipment to perform well in a variety of industrial scenarios.

[0040] Example 1,

[0041] Please see Figures 1 to 8 This is a novel steel material conveying line, comprising: a head assembly 7, a tail and tension assembly 9, a surface-enlarging roller 6, and a frame 4. The frame 4 is equipped with an upper idler roller 2, a lower idler roller 5, a vertical roller 10, a baffle assembly 3, and a buffer chute 8. The idler rollers are equipped with a special conveyor belt 1 for transporting materials. The special conveyor belt 1 bypasses the head assembly 7, the tail and tension assembly 9, and the surface-enlarging roller 6, conveying materials from the tail to the head buffer chute 8. Figure 1 As shown.

[0042] In this embodiment, the tail section and tensioning assembly 9 can be a spiral tensioning assembly or a tower tensioning assembly. The tail section and tensioning assembly 9 can be a separate tail section assembly and a counterweight tensioning assembly. The spiral tensioning assembly, tower tensioning assembly, and tail section assembly are generally located at the tail end of the entire conveyor line, while the counterweight tensioning assembly is generally located in the middle of the entire conveyor line.

[0043] In this embodiment, the redirecting wheel in the counterweight tensioning assembly is the same type as the surface-enlarging wheel 6, and needs to adapt to the structural form of the special conveyor belt 1.

[0044] In this embodiment, the head assembly 7 includes a drive unit, a device mounting frame, and a drive roller. The drive unit drives the drive roller, which in turn drives the special conveyor belt 1, providing power for the forward movement of the special conveyor belt 1. The drive unit and the drive roller are mounted on the device mounting frame.

[0045] In this embodiment, the upper idler roller 2, lower idler roller 5, vertical roller 10, baffle assembly 3, surface-enhancing wheel 6, buffer chute 8, and frame 4 can be installed by bolting or welding. The upper idler roller 2 is installed on the frame 4 at certain intervals for the carrying section of the special conveyor belt 1. The lower idler roller 2 is installed on the frame 4 at certain intervals for the return section of the special conveyor belt 1, such as... Figure 1 and Figure 2 As shown.

[0046] In this embodiment, the entire conveyor line utilizes the head assembly 7 to drive the special conveyor belt 1, so that the steel material is transported from the tail end to the head buffer chute 8 and falls into the downstream conveyor line, thus completing the continuous transport of the steel material.

[0047] In this embodiment, the special conveyor belt 1 includes a base belt 101 and replaceable short belts 102. The replaceable short belts 102 include short belts 103 and connecting components 104. The replaceable short belts 102 are sequentially and tightly installed on the base belt 101, covering the entire base belt 101 to form a flat surface for direct contact with the conveyed material, thus avoiding direct contact between the base belt 101 and the conveyed material. Figures 4-6 As shown.

[0048] In this embodiment, the replaceable short belt 102 can be replaced with the short belt 103 according to the wear condition. If, in subsequent engineering applications, the short belt 103 of the replaceable short belt 102 becomes severely worn due to long-term operation or is locally punctured due to impact from individual materials, the general connecting parts can be loosened to achieve quick replacement of the short belt 103.

[0049] The special conveyor belt 1 has a structure that extends the life of the base belt 1, improves the wear resistance and tear resistance of the entire conveyor belt, and reduces the maintenance cost of the entire conveyor line.

[0050] The short strap 103 and the connecting component 104 can be fixedly connected using general connectors, and the number of connecting components 104 can be one or more.

[0051] In this embodiment, the baffle assembly 3 consists of two side barriers 301, mounting brackets 302, and small blocks 303. The side barriers 301, small blocks 303, and the special conveyor belt 1 form a material conveying area, preventing material from spilling to the sides. The side barriers 301 are mounted on the frame 4 via mounting brackets 302. The installation method between the side barriers 301 and the mounting brackets 302 can be bolted or welded. The side barriers 301 and the small blocks 303 are bolted together, and the small blocks 303 have a certain adjustment range, such as... Figure 2 As shown.

[0052] In this embodiment, the buffer chute 8 is generally installed at the transfer point between two conveyor lines. The buffer chute 8 is an arc-shaped or multi-stage chute with an angle that gradually decreases from large to small. It is used to reduce the angle at which the material at the transfer point cuts into the downstream conveyor line, thereby mitigating the impact of the material and extending the service life of the equipment.

[0053] In this embodiment, the vertical roller 10 is installed at the carrying section and return section of the special conveyor belt 1 to correct the belt's deviation, such as... Figure 7 As shown.

[0054] In this embodiment, the vertical roller 10 can be installed between two sets of idler rollers. Alternatively, the vertical roller can be installed on an idler roller frame.

[0055] In this embodiment, the lower idler roller 5 includes a lower idler roller body 501 and a lower idler roller frame 502. The lower idler roller frame 502 is used to mount the idler roller 501 and the vertical roller 10. The lower idler roller 5 is provided with one or more lower idler roller bodies.

[0056] In this embodiment, multiple lower idler roller bodies 501 are installed on both sides and in the middle of the special conveyor belt 1, which can evenly support the special conveyor belt 1. Alternatively, one lower idler roller body 501 may be installed in the middle of the special conveyor belt 1, such as... Figure 2 and Figure 3 As shown.

[0057] In this embodiment, the face-enlarging wheel 6 includes a face-enlarging wheel body 601 and a face-enlarging wheel frame 602, used to increase the transmission wrap angle and improve transmission efficiency. The face-enlarging wheel frame 602 includes a mounting base and a mounting shaft, used to mount the face-enlarging wheel body 601. The face-enlarging wheel body 601 is provided with one or more wheel bodies, such as... Figure 8 As shown.

[0058] Multiple wheels can be evenly mounted on the mounting shaft. Alternatively, one wheel can be mounted in the middle of the mounting shaft.

[0059] Example 2,

[0060] Unlike Embodiment 1, the short strip 103 and the connecting component 104 are welded together, with the connecting component 104 fixedly welded to the short strip 103.

[0061] In summary, this utility model improves the wear resistance, tear resistance, and replaceability of the conveyor belt by replacing the traditional conveyor belt with a special conveyor belt, thus enabling the conveying of steel materials such as scrap steel with complex block size, sharp edges, high abrasiveness, and impact characteristics.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
