Abstract
Description
Technical Field
[0001] This utility model belongs to the field of metallurgical engineering technology, specifically relating to a liquid steel slag crushing device made from rectangular billet scrap. Background Technology
[0002] In the iron and steel metallurgical industry, converter smelting is a crucial step in steel production, generating a large amount of molten steel slag. This molten steel slag is hot and complex in composition; if not treated promptly, it not only occupies significant space but can also pollute the environment. The emergence of molten steel slag crushing devices allows for the crushing of slag while it is still in a molten state, laying the foundation for subsequent resource utilization, greatly improving slag processing efficiency, reducing potential environmental hazards, and playing an indispensable role in the entire steel production process.
[0003] Currently, the core component of commonly used liquid steel slag crushing devices is the crushing roller. Several teeth are evenly welded to the outer wall of the crushing roller, and toothed sleeves are fitted onto the teeth, which are then fixed to the teeth by pins. During operation, a motor drives the crushing roller to rotate, causing the teeth to rotate accordingly, which in turn drives the toothed sleeves to rotate synchronously. The high-speed rotating toothed sleeves come into contact with the liquid steel slag, repeatedly crushing it to achieve the purpose of crushing. This design, to a certain extent, achieves the crushing of liquid steel slag and meets the basic needs of production.
[0004] However, in practical applications, liquefied steel slag has the characteristics of high temperature and high hardness. During the rolling process, intense friction and impact occur between the toothed sleeve and the liquefied steel slag, leading to severe wear of the toothed sleeve. After a period of use, the toothed sleeve is prone to cracking due to wear and eventually detaches from the tooth root. Once the toothed sleeve detaches, the tooth root comes into direct contact with the liquefied steel slag, causing damage to the tooth root and making it impossible to reattach the toothed sleeve. At this point, to restore normal operation of the device, the operator must stop the machine, cut the damaged tooth root off the rolling roller, and re-weld a new tooth root. This entire process not only consumes a lot of manpower and resources, but also causes the production line to be interrupted due to downtime for maintenance, seriously affecting the production schedule and increasing the company's production costs. Utility Model Content
[0005] This utility model addresses the problem of tooth sleeve detachment leading to tooth root damage and inability to reinstall the tooth sleeve. It provides a liquid steel slag crushing device made from rectangular blank scraps that replaces the tooth sleeves and has no tooth root inside, thus eliminating concerns about tooth root damage.
[0006] To solve the above problems, the technical solution adopted by this utility model is a liquid steel slag crushing device made from rectangular billet scrap, including a crushing roller, a mounting base fixed on the outer wall of the crushing roller, a locking hole penetrating the mounting base on the side wall of the mounting base, an installation opening on the top of the mounting base, the installation opening communicating with the locking hole, and a rectangular billet scrap being placed inside the installation opening, one end of the rectangular billet scrap being inserted into the installation opening, and a connecting hole penetrating the rectangular billet scrap being provided at the end of the rectangular billet scrap inserted into the installation opening, and the position of the connecting hole corresponding to the locking hole, and a locking element penetrating the connecting hole and the locking hole being installed inside the connecting hole.
[0007] In this technical solution, the mounting base is fixed to the crushing roller. By passing the locking element through the connecting hole and locking hole, the rectangular billet scrap can be fixed to the mounting base. When the crushing roller starts to rotate, the mounting base drives the rectangular billet scrap to rotate synchronously, allowing the rectangular billet scrap to crush the liquid steel slag. The rectangular billet scrap uses a solid structure, which significantly improves wear resistance compared to the hollow structure of the toothed sleeve. The mounting base is positioned close to the crushing roller, so even if the rectangular billet scrap wears down during use, it only shortens in length, preventing the mounting base from directly contacting the liquid steel slag and avoiding damage to the mounting base. Therefore, only periodic replacement of the rectangular billet scrap is needed to ensure the stable operation of the device. Moreover, the rectangular billet scrap itself is waste material, effectively saving costs. Therefore, compared to the traditional solution of fixing the toothed sleeve to the outer wall of the crushing roller, this solution directly fixes the mounting base to the crushing roller, securing the rectangular billet scrap to the mounting base. The rectangular billet scrap uses existing materials, requiring no additional processing, further reducing costs. Furthermore, the wear and tear of the rectangular blank will not affect the mounting base, ensuring the smooth replacement of the rectangular blank.
[0008] Furthermore, the locking component is a locking pin, which includes a pin head and a pin shaft. A pin hole is provided on the outer wall of the pin shaft, and a cotter pin is installed inside the pin hole. The locking pin passes through the connecting hole and the locking hole, fixing the rectangular billet scrap to the mounting base. This ensures that the rectangular billet scrap will not loosen or fall off during the crushing process of the rolling roller driving the rolling roller to crush the liquefied steel slag, guaranteeing the stability and safety of the entire working process. The cotter pin is installed in the pin hole on the outer wall of the pin shaft. This structure makes disassembly of the locking pin convenient. Simply remove the cotter pin to pull the locking pin out of the connecting hole and the locking hole, thereby enabling operations such as replacing the rectangular billet scrap, improving the convenience and efficiency of equipment maintenance. The presence of the cotter pin effectively prevents the locking pin from loosening or falling off due to vibration or other factors during operation. When the cotter pin is correctly installed, it restricts the axial movement of the pin shaft, ensuring that the locking pin is always in the locked position during operation, further enhancing the reliability of the connection.
[0009] Furthermore, the locking component is a locking bolt, which includes a bolt head and a bolt shank, with a lock nut mounted on the bolt shank. The locking bolt passes through the connecting hole and the locking hole via the bolt shank, and then the lock nut is tightened. This generates a large preload, ensuring a tight connection between the rectangular billet and the mounting base. When the rolling roller rotates and drives the rectangular billet to crush the molten steel slag, it effectively prevents the rectangular billet from loosening or shifting, ensuring stable operation of the device. The lock nut, in conjunction with the bolt shank, provides a certain degree of anti-loosening function. During device operation, even under vibration or other external forces, the lock nut remains firmly in place, preventing loosening and ensuring the reliability of the locking bolt connection, thus reducing the risk of device malfunction due to loose connections.
[0010] Furthermore, a locking spring is installed inside the mounting port. One end of the locking spring is fixedly connected to the bottom of the mounting port, and the other end abuts against the rectangular billet scrap. During operation, due to vibration, impact, and other factors, the locking component may loosen, causing the rectangular billet scrap to fail to hold. The locking spring continuously applies a pushing force to the rectangular billet scrap, ensuring the connecting hole tightly fits the locking component, increasing the friction between them, effectively preventing the locking component from shifting or loosening due to vibration, ensuring stable locking of the rectangular billet scrap, and reducing the risk of device failure. In addition, when the rectangular billet scrap is crushed and rolled over liquefied steel slag, it will be subjected to reaction forces and impact forces. The locking spring can act as a buffer and shock absorber, absorbing and mitigating some of the impact forces, reducing damage to the rectangular billet scrap, mounting base, and the entire rolling device, and extending the service life of the device.
[0011] Furthermore, a buffer pad is fixed to the side wall of the mounting port. During the installation of the rectangular billet scrap into the mounting port and during the operation of the device, the buffer pad can prevent rigid contact between the rectangular billet scrap and the mounting port, reducing wear and scratches on the mounting base, thereby extending the service life of the mounting base. In addition, the buffer pad can fill the gap between the rectangular billet scrap and the mounting port, playing a certain positioning and fastening role, making the rectangular billet scrap more stable within the mounting port, preventing it from shaking or shifting during operation, and further improving the reliability of the device operation.
[0012] Furthermore, the bottom surface of the mounting base is curved, with an arc shape and the curvature of the arc being the same as that of the outer wall of the rolling mill. The bottom surface of the mounting base fits tightly against the outer wall of the rolling mill, allowing the rectangular billet residue to better follow the rotation of the rolling mill when rolling molten steel slag, maintaining a stable working state, and avoiding the rectangular billet residue from shaking or shifting due to gaps or mismatches between the mounting base and the rolling mill, which would affect the rolling effect.
[0013] Furthermore, the mounting base has first reinforcing ribs on both sides perpendicular to the end face of the roller. The sides of the first reinforcing ribs are fixedly connected to the mounting base, and the bottom surface of the first reinforcing ribs is smoothly connected to the bottom surface of the mounting base. The bottom surface of the first reinforcing ribs is also curved, with an arc shape and a curvature identical to that of the outer wall of the roller. These first reinforcing ribs increase the structural strength and rigidity of the mounting base, making it less prone to deformation when subjected to the pressure of the roller and the rolling pressure of the rectangular billet residue on the molten steel slag. This helps ensure the stability of the mounting base, extends its service life, and reduces equipment failures caused by structural deformation. During operation, the reinforcing ribs distribute the pressure acting on the mounting base more evenly to various parts. Because their bottom surface is in contact with the outer wall of the roller, they better transmit pressure to the roller, preventing excessive local pressure on the mounting base, thus protecting both the mounting base and the roller and reducing wear and damage.
[0014] Furthermore, there are four first reinforcing ribs, evenly distributed on both sides of the mounting base, with the two ribs on the same side of the mounting base symmetrically distributed along the central plane of the mounting base. This distribution helps to more evenly transfer the force borne by the mounting base to the rolling roller and the entire support structure of the device. Because the first reinforcing ribs are evenly and symmetrically distributed, the force can be transmitted more orderly and evenly during the process, avoiding stress concentration, thereby improving the overall load-bearing capacity and reliability of the device.
[0015] Furthermore, the mounting base has second reinforcing ribs on both sides parallel to the end face of the rolling mill, and the sides of the second reinforcing ribs are fixedly connected to the mounting base. During operation, the sides of the mounting base parallel to the end face of the rolling mill are subjected to lateral pressure from the rectangular billet residue and molten steel slag, as well as the torque generated by the rotation of the rolling mill. The second reinforcing ribs effectively enhance the structural strength of these sides, improve the mounting base's resistance to deformation and damage, and enable it to better withstand various external forces during operation, ensuring the normal operation of the device.
[0016] Furthermore, adjacent mounting seats are evenly distributed along the axial direction of the roller, and are staggered circumferentially distributed on the outer wall of the roller. The uniform axial distribution ensures that the molten steel slag is uniformly compacted along the entire length of the roller, avoiding localized over- or under-compaction and guaranteeing the consistency and stability of the molten steel slag treatment. The staggered circumferential distribution allows the rectangular blanks on the mounting seats to cover different areas of the roller's outer wall, enabling more comprehensive crushing and processing of the molten steel slag during the compaction process. This reduces insufficiently compacted dead zones and improves the efficiency and quality of steel slag treatment.
[0017] As can be seen from the above technical solution, the advantages of this utility model are as follows: A mounting seat is fixed to the outer surface of the crushing roller, and a locking member passes through the locking hole of the mounting seat and the connection hole of the rectangular billet residue to achieve rapid fixation. The rectangular billet residue adopts a solid structure design, which has superior wear resistance compared to traditional hollow toothed sleeves. During operation, the mounting seat drives the rectangular billet residue to rotate synchronously to complete the steel slag crushing operation. First, the mounting seat is positioned close to the crushing roller, ensuring that wear on the rectangular billet residue only leads to a reduction in length and does not expose the mounting seat, fundamentally avoiding direct contact wear between the mounting seat and the steel slag. Second, using waste material as the rectangular billet residue eliminates the need for additional processing and significantly reduces production costs. Third, replacement only requires targeting the rectangular billet residue, making maintenance convenient and maintaining long-term device stability. In summary, compared to the traditional toothed sleeve structure, this solution's mounting seat does not wear, enhancing operational reliability; only the rectangular billet residue needs replacement, reducing maintenance costs; and the resource utilization of the rectangular billet residue improves material utilization, thereby comprehensively improving the economy and service life of the liquid steel slag crushing device.

Detailed Implementation
[0027] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0028] A liquid steel slag crushing device manufactured using rectangular billet scrap, such as Figure 1 As shown, the device includes a crushing roller 1. The outer wall of the crushing roller 1 serves as the fixed position for the mounting base 2, and the mounting base 2 is securely installed by welding. The top of the mounting base 2 has a mounting opening 21, into which a rectangular billet scrap 3 is inserted and fixed. The rectangular billet scrap 3 is the short end of a standard rectangular billet that is not long enough after cutting. The rectangular billet scrap 3 and the mounting base 2 are connected by a detachable design, which facilitates the replacement of the rectangular billet scrap 3 later. When the crushing roller 1 starts to rotate, the mounting base 2 drives the rectangular billet scrap 3 to rotate synchronously due to the welded connection between the mounting base 2 and the crushing roller 1, thereby enabling the rectangular billet scrap 3 to crush the liquid steel slag.
[0029] In this specific embodiment, the roller 1 adopts the following structure: the roller 1 is cylindrical in shape, with a connecting shaft fixed inside, the axis of which coincides with the axis of the roller 1. Both ends of the connecting shaft are mounted on the existing frame using bearings, ensuring that the roller 1 can rotate flexibly. The mounting base 2 is fixed to the outer wall of the roller 1 by welding. In this embodiment, a total of forty mounting bases 2 are provided, divided into four groups. The four groups of mounting bases 2 are evenly distributed around the axis of the roller 1 along the circumferential outer wall of the roller 1. Each group contains ten mounting bases 2, symmetrically distributed with respect to the central cross-section of the roller 1; that is, the five mounting bases 2 closest to one end face of the roller 1 are symmetrically distributed with respect to the five mounting bases 2 closest to the other end face of the roller 1. Regarding the five mounting seats 2 located near the same side end face of the rolling roller 1, they are evenly distributed along the axial direction of the rolling roller 1, and adjacent mounting seats 2 are staggered in the circumferential direction of the outer wall of the rolling roller 1.
[0030] like Figure 2 As shown, in this specific embodiment, the mounting base 2 adopts the following structure: the mounting base 2 is designed as a rectangle. The mounting opening 21 is a rectangular slot, and the cross-sectional shape of the mounting opening 21 perfectly matches the cross-sectional shape of the rectangular blank 3, thereby ensuring that the rectangular blank 3 can be tightly inserted into the mounting opening 21. Figure 4 As shown, a locking spring 6 is provided inside the mounting opening 21. One end of the locking spring 6 is connected to the bottom of the mounting opening 21 by welding, and the other end abuts against the rectangular blank 3. Buffer pads 211 are fixed to the four side walls of the mounting opening 21 by adhesive bonding. The presence of the buffer pads 211 avoids rigid contact between the rectangular blank 3 and the mounting opening 21, effectively reducing wear and scratches on the mounting base 2 caused by the rectangular blank 3, ultimately extending the service life of the mounting base 2.
[0031] like Figure 3 As shown, the bottom surface of the mounting base 2 is curved, and the curvature of this curved surface is precisely calculated to be the same as the curvature of the outer wall of the rolling roller 1. Therefore, the bottom surface of the mounting base 2 and the outer wall of the rolling roller 1 can be seamlessly welded. Figure 5As shown, the mounting base 2 has first reinforcing ribs 7 on both sides perpendicular to the end face of the rolling roller 1. The sides of the first reinforcing ribs 7 are connected to the mounting base 2 by welding, and the bottom surface of the first reinforcing ribs 7 is smoothly connected to the bottom surface of the mounting base 2. Furthermore, the bottom surface of the first reinforcing ribs 7 is also curved, with an arc shape, and its curvature is the same as the curvature of the outer wall of the rolling roller 1. This allows for seamless welding between the bottom surface of the first reinforcing ribs 7 and the outer wall of the rolling roller 1. In this embodiment, a total of four first reinforcing ribs 7 are provided, evenly distributed on both sides of the mounting base 2. The two first reinforcing ribs 7 located on the same side of the mounting base 2 are symmetrically distributed along the central plane of the mounting base 2. The provision of the first reinforcing ribs 7 significantly increases the structural strength and rigidity of the mounting base 2, making it less prone to deformation when subjected to the pressure of the rolling roller 1 and the rolling pressure of the rectangular billet residue 3 on the liquid steel slag.
[0032] The mounting base 2 has two sides parallel to the end face of the roller 1, each equipped with a second reinforcing rib 8. The sides of the second reinforcing rib 8 are connected to the mounting base 2 by welding, and the bottom surface of the second reinforcing rib 8 is seamlessly welded to the outer wall of the roller 1. The second reinforcing rib 8 can effectively enhance the structural strength of the sides, improve the mounting base 2's resistance to deformation and damage, and allow the mounting base 2 to better withstand various external forces during operation, thereby ensuring the normal operation of the device.
[0033] The side wall of the mounting base 2 has a locking hole 22 that penetrates the mounting base 2 and communicates with the mounting opening 21. A locking element is installed in the locking hole 22 to fix the rectangular blank slab 3 onto the mounting base 2. The locking element has two specific structures. For example... Figure 6 As shown, Structure 1: The locking component is a locking pin 4, which consists of a pin head 44 and a pin shank 41. The outer wall of the pin shank 41 has a pin hole 42, and a cotter pin 43 is installed in the pin hole 42. The cotter pin 43 is installed in the pin hole 42 on the outer wall of the pin shank 41. This structural design makes it easier to disassemble the locking pin 4 when necessary. Structure 2: The locking component is a locking bolt 5, which consists of a bolt head 53 and a bolt shank 51. A locking nut 52 is installed on the bolt shank 51. The locking nut 52 here is a high-temperature resistant anti-loosening nut to adapt to the working environment of the device and ensure the reliability of the locking.
[0034] like Figure 7As shown, in this specific embodiment, the rectangular blank scrap 3 adopts the following structure: the rectangular blank scrap 3 is generally in the shape of a rectangular rod, and one end of the rectangular blank scrap 3 is used to insert into the mounting port 21. The end of the rectangular blank scrap 3 inserted into the mounting port 21 is provided with a connecting hole 31 that penetrates the rectangular blank scrap 3, and the cross-section of the connecting hole 31 is rectangular. The position of the connecting hole 31 corresponds to the locking hole 22, which means that the locking member can be inserted from the locking hole 22 on one side of the mounting base 2, pass through the connecting hole 31, and finally exit from the locking hole 22 on the other side of the mounting base 2.
[0035] The specific usage process of this utility model is as follows: First, insert the end of the rectangular blank 3 with the connecting hole 31 into the mounting opening 21 of the mounting base 2. During the insertion process, the end of the rectangular blank 3 will compress the locking spring 6. When the connecting hole 31 on the rectangular blank 3 is aligned with the locking hole 22 on the mounting base 2, insert the locking member through the locking hole 22 on one side of the mounting base 2, pass through the connecting hole 31 of the rectangular blank 3, and finally exit through the locking hole 22 on the other side of the mounting base 2. Through this operation, the rectangular blank 3 is fixed on the mounting base 2.
[0036] After installation, start the device to rotate the crushing roller 1. As the roller 1 rotates, due to the welded connection between the mounting base 2 and the roller 1, the mounting base 2 will drive the rectangular billet scrap 3 to rotate synchronously, allowing the rectangular billet scrap 3 to crush the liquid steel slag. When the rectangular billet scrap 3 becomes too short due to severe wear and can no longer effectively crush the liquid steel slag, stop the rotation of the roller 1, open the locking mechanism, remove the severely worn rectangular billet scrap 3, and replace it with a new one. After installing the new rectangular billet scrap 3, reinstall the locking mechanism to fix the new rectangular billet scrap 3 on the mounting base 2. Then rotate the roller 1 again to continue crushing the liquid steel slag.
[0037] As can be seen from the above embodiments, the beneficial effects of this utility model are as follows: a mounting seat is fixed on the outer surface of the crushing roller, and a locking member passes through the locking hole of the mounting seat and the connection hole of the rectangular billet residue to achieve rapid fixation. The rectangular billet residue adopts a solid structure design, which has better wear resistance than the traditional hollow toothed sleeve. When the device is running, the mounting seat drives the rectangular billet residue to rotate synchronously to complete the steel slag crushing operation. First, the mounting seat is located close to the crushing roller, ensuring that the wear of the rectangular billet residue only leads to a reduction in length and does not expose the mounting seat, fundamentally avoiding direct contact wear between the mounting seat and the steel slag; second, using waste materials as rectangular billet residue eliminates the need for additional processing and significantly reduces production costs; third, replacement operations only need to be performed on the rectangular billet residue, making maintenance convenient and maintaining the stability of the device for a long time. In summary, compared with the traditional toothed sleeve structure, the mounting seat of this solution will not wear, enhancing operational reliability; only the rectangular billet residue needs to be replaced, reducing maintenance costs; the rectangular billet residue is utilized as a resource, improving material utilization rate, thereby improving the overall economy and service life of the liquid steel slag crushing device.
