Description

Technical Field

[0001] This utility model relates to the field of metallurgical technology, and in particular to a multi-station molten iron slag removal system. Background Technology

[0002] For most steel grades, excessive sulfur content can negatively impact their processing and performance, necessitating hot metal desulfurization to reduce sulfur content. Existing hot metal desulfurization methods typically employ dual-station desulfurization stations, requiring two fixed slag removers, each corresponding to one desulfurization station. These stations include both agitation and slag removal processes. During the agitation process, the slag removers are in standby mode. The use of two slag removers results in high investment costs and maintenance requirements. Therefore, a multi-station hot metal slag removal system is urgently needed to address these issues. Utility Model Content

[0003] To solve the above problems, this utility model provides a multi-station molten iron slag removal system, including a slag remover. The slag remover has a walking mechanism at its bottom. The walking mechanism is movably mounted on a walking track and is equipped with a drive unit for driving it to move along the walking track. The walking track connects multiple desulfurization stations in series.

[0004] Furthermore, it also includes an anti-tipping mechanism, which includes an anti-tipping track and an anti-tipping wheel assembly. The anti-tipping track is disposed beside the travel track and parallel to the travel track. The anti-tipping track has an abutment surface that is parallel to or perpendicular to the vertical. The anti-tipping wheel assembly is disposed on the travel mechanism, and the anti-tipping wheels of the anti-tipping wheel assembly abut against the abutment surface and are axially parallel to the abutment surface.

[0005] Furthermore, the anti-tipping track and the traveling track are an integral structure, and the anti-tipping track and the traveling track form a Z-shaped track.

[0006] Furthermore, the anti-rollover wheel assembly also includes a housing and an elastic element. The housing is disposed on the traveling mechanism, the anti-rollover wheel is movably disposed on the housing, and the elastic element is pre-tightened between the housing and the anti-rollover wheel. The elastic direction of the elastic element is perpendicular to the contact surface.

[0007] Furthermore, the anti-tipping track includes multiple first track segments and multiple second track segments, with each first track segment and second track segment arranged alternately in sequence. Each first track segment is set in a one-to-one correspondence with a desulfurization station, and the distance between the contact surface of the first track segment and the shell is smaller than the distance between the contact surface of the second track segment and the shell.

[0008] Furthermore, the anti-tipping wheel assembly also includes a slider, which is slidably connected to the housing, the anti-tipping wheel is connected to the slider, and the elastic element is pre-tightened between the housing and the slider.

[0009] Furthermore, the anti-rollover wheel assembly also includes a guide post, which is disposed at the bottom of the housing and engages with the elastic element for guidance.

[0010] Furthermore, the elastic element is a disc spring.

[0011] Furthermore, the traveling mechanism includes a traveling vehicle body and a traveling wheel set. The muck loader is mounted on the traveling vehicle body, and the traveling vehicle body is supported on the traveling track by the traveling wheel set. The drive unit is connected to the traveling wheel set.

[0012] Furthermore, the walking wheel set includes a driving wheel and a driven wheel, which are respectively disposed at both ends of the walking vehicle body, and the drive unit is connected to the driving wheel.

[0013] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0014] 1) The multi-station molten iron slag removal system provided by this utility model connects each desulfurization station in series through a walking track. The slag remover can move on the walking track through the walking mechanism, so that multiple desulfurization stations can share one slag remover, saving equipment investment costs and maintenance costs. The slag remover can remove slag while moving, making the movement trajectory of the slag remover more flexible and improving the operation efficiency.

[0015] 2) The multi-station molten iron slag removal system provided by this utility model is equipped with an anti-tipping mechanism to prevent the slag removal machine from tipping over. The anti-tipping mechanism achieves a flexible clamping design through elastic elements, requiring no additional power input, with a simple structure and maintenance-free operation.

[0016] 3) The multi-station molten iron slag removal system provided by this utility model adopts a non-planar design for the contact surface of the anti-tipping track, which allows the anti-tipping wheel group to exert different pressures on the contact surface during the movement of the traveling mechanism. This results in a large compression of the elastic element and a large anti-tipping torque in the first track segment, thus achieving a good anti-tipping effect. In the second track segment, the compression of the elastic element is relatively small, resulting in a small anti-tipping torque and a small moving drive torque, which facilitates the movement of the traveling mechanism.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. In the accompanying drawings, the dimensions and relative dimensions of certain parts may be enlarged for clarity.

For example, they can be fixed connections, detachable connections, or integral connections; they can be mechanical connections or electrical connections; they can be direct connections or indirect connections through an intermediate medium; they can be internal connections between two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0024] In the description of this utility model, the terms "upper", "lower", "left", "right", "front", "back", "center", "horizontal", "vertical", "top", "bottom", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, in the description of this utility model, the terms "first" and "second" are used merely for descriptive distinction and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Additionally, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0026] As per the instruction manual Figure 1 As shown, this utility model provides a multi-station molten iron slag removal system, including a slag remover 1. The slag remover 1 has a traveling mechanism at its bottom, which is movably mounted on a traveling track 3 and equipped with a drive unit for driving it to move along the traveling track 3. The traveling track 3 connects multiple desulfurization stations in series. The traveling mechanism at the bottom of the slag remover 1 is referred to as the first traveling mechanism 2, and the drive unit connected to the first traveling mechanism 2 is referred to as the first drive unit 4.

[0027] Specifically, the walking track 3 is laid out along each desulfurization station. "Multiple" refers to two or more stations. In this embodiment, the slag removal system is used for two desulfurization stations, so the walking track 3 is laid out along both stations. The first walking mechanism 2 drives the slag remover 1 to move along the walking track 3, thereby enabling slag removal operations at both desulfurization stations. In actual use, the first walking mechanism 2 moves along the walking track 3 to the molten iron ladle 6 at the desulfurization station, and the molten iron ladle 6 tilts to enter the slag removal operation.

[0028] Optimized implementation methods, as shown in the appendix to the instruction manual. Figure 2 As shown, it also includes an anti-tipping mechanism 5, which includes an anti-tipping track 51 and an anti-tipping wheel assembly 52. ​​The anti-tipping track 51 is disposed beside and parallel to the traveling track 3, and has an abutment surface that is parallel to or perpendicular to the vertical. The anti-tipping wheel assembly 52 is disposed on the first traveling mechanism 2, and the anti-tipping wheel 523 of the anti-tipping wheel assembly 52 abuts against the abutment surface and is axially parallel to the abutment surface. Specifically, in order to prevent the muck loader 1 from tipping over during travel or muck removal, an anti-tipping track 51 is provided on the traveling track 3, and the anti-tipping wheel assembly 52 cooperates with the anti-tipping track 51 to provide a pulling force to prevent the muck loader 1 from tipping over.

[0029] Specifically, there are two sets of walking tracks 3, which are arranged in parallel and anchored to the ground. There are also two sets of anti-tipping tracks 51, which are arranged in a one-to-one correspondence with the walking tracks 3 and are located inside the walking tracks 3. The anti-tipping tracks 51 are anchored to the ground, and the anti-tipping wheel set 52 abuts against the top surface or side wall of the anti-tipping track 51.

[0030] Preferably, to improve track strength, the anti-tipping track 52 and the traveling track 3 are an integral structure, and the anti-tipping track 52 and the traveling track 3 together form a Z-shaped track. Specifically, the Z-shaped track can be formed by integrally molding a 7-shaped track and an L-shaped track, or by assembling a 7-shaped track and an L-shaped track.

[0031] As one specific implementation, the anti-tipping track 51 is 7-shaped, with two sets of anti-tipping tracks 51 symmetrically arranged. The inner side of the top surface of each anti-tipping track 51 forms an abutment surface, which is perpendicular to the vertical direction and located directly above the anti-tipping wheel assembly 52. ​​This abutment surface provides force to the anti-tipping wheel assembly 52, preventing the muck loader 1 from tipping over. In this embodiment, the abutment surface is preferably the inner side of the top surface of the anti-tipping track 51, and each anti-tipping track 51 corresponds to at least one set of anti-tipping wheel assemblies 52.

[0032] As one specific implementation, the inner side of the anti-tipping track 51 forms an abutment surface, the plate surface of the abutment surface is parallel to the vertical direction, the axial direction of the anti-tipping wheel assembly 52 is parallel to the vertical direction, the anti-tipping wheel assembly 52 abuts against the side wall of the anti-tipping track 51, and provides force when the muck loader tilts, so as to prevent the muck loader 1 from tilting.

[0033] Optimized implementation methods, as shown in the appendix to the instruction manual. Figure 3 As shown, the anti-tipping wheel assembly 52 also includes a housing 521 and an elastic element 524. The housing 521 is disposed on the first traveling mechanism 2, the anti-tipping wheel 523 is movably disposed on the housing 521, and the elastic element 524 is pre-tightened between the housing 521 and the anti-tipping wheel 523. The elastic direction of the elastic element 524 is perpendicular to the contact surface.

[0034] Specifically, the anti-tipping wheel 523 is slidably connected to the housing 521, with its sliding direction perpendicular to the contact surface. The elastic direction of the elastic element 524 is perpendicular to the contact surface. Under the action of the elastic element 524, the anti-tipping wheel 523 is pressed against the anti-tipping track 51, thus playing a role in preventing tipping and resisting vibration. The anti-tipping mechanism is a flexible pressing mechanism, requiring no additional power input device, with a simple structure and maintenance-free operation.

[0035] Preferably, the anti-tipping wheel assembly 52 further includes a slider 522, which is slidably connected to the housing 521. The anti-tipping wheel 523 is connected to the slider 522, and the elastic element 524 is pre-tightened between the housing 521 and the slider 522. The slider 522 and the housing 521 can be slidably connected via a slide rail structure. The anti-tipping wheel 523 is connected to the slider 522 via a pin 525. A rolling bearing 526 is provided between the pin 525 and the anti-tipping wheel 523. The anti-tipping wheel 523 can rotate on the pin 525 and thus move along the anti-tipping track 51 during the travel of the first traveling mechanism 2. A receiving cavity is formed between the bottom of the housing 521 and the slider 522. The elastic element 524 is pre-tightened in the receiving cavity, and both ends of the elastic element 524 abut against the housing 521 and the slider 522, respectively.

[0036] In an optimized implementation, the anti-tipping track 51 includes multiple first track segments and multiple second track segments. The first and second track segments are arranged alternately in sequence. Each first track segment corresponds to a desulfurization station. The distance between the contact surface of the first track segment and the shell 521 is smaller than the distance between the contact surface of the second track segment and the shell 521. Using the contact surface being perpendicular to the vertical direction and the lower surface of the Z-shaped track as the contact surface, along the track length, the anti-tipping track 51 includes first and second track segments. The first track segment corresponds to the desulfurization station and is used for slag removal by the slag remover, which can be designated as the slag removal working position. The second track segment is used for the slag remover's movement and is designated as the non-working position. The elevation of the contact surface changes along the track length; it is lower in the slag removal working position and higher in other positions. The use of a gradually changing elevation on the contact surface allows the anti-tipping wheel 523 to exert different pressures on the contact surface as the first traveling mechanism 2 moves along the track. When the first traveling mechanism 2 moves to the slag removal working position, the elastic element 524 has a large compression amount, a large anti-tipping torque, and a good anti-tipping effect. When it is not in the working position, the elastic element 524 has a relatively small compression amount, a small anti-tipping torque, and a small moving drive torque, which makes it easier for the first traveling mechanism 2 to move on the track.

[0037] Preferably, the first track segment and the second track segment are connected by an arc-shaped track segment, which can be chamfered to form a gradual connection, so that the anti-tipping wheel 523 can move smoothly on the anti-tipping track 51.

[0038] In the optimized implementation, the elastic element 524 is a disc spring, which has high space utilization and makes the structure of the anti-tipping wheel assembly 52 compact.

[0039] In an optimized implementation, the anti-tipping wheel assembly 52 further includes a guide post 527, which is disposed at the bottom of the housing 521 and guides the elastic element 524. Specifically, the elastic element 524 is a disc spring, which is sleeved on the guide post 527 and extends and retracts along the guide post 527. The guide post 527 is disposed within the accommodating cavity of the housing 521, and its height is set according to requirements. While satisfying the guiding function of the elastic element 524, it does not affect the anti-tipping wheel 523. When the anti-tipping wheel 523 descends to its lowest point, there is still a gap between the anti-tipping wheel 523 and the guide post 527.

[0040] Specifically, the anti-tipping wheel assembly 52 also includes a pressure cover 528, a through hole is provided at the bottom of the housing 521, the guide post 527 is disposed on the pressure cover 528, and the pressure cover 528 is disposed at the through hole and connected to the housing 521.

[0041] In an optimized implementation, the slider 522 is provided with a clearance hole, which is provided corresponding to the guide post 527.

[0042] In an optimized implementation, the first traveling mechanism 2 includes a traveling vehicle body 21 and a traveling wheel set. The muck loader 1 is mounted on the traveling vehicle body 21. The traveling vehicle body 21 is supported on the traveling track 3 by the traveling wheel set. The first drive unit 4 is connected to the traveling wheel set and drives the traveling wheel set to move along the traveling track 3.

[0043] Preferably, the bottom of the vehicle body 21 is provided with a mounting part 211 extending to the inner side of the anti-tipping track 51. The mounting part 211 is inverted T-shaped, and the anti-tipping wheel set 52 is disposed on the mounting part 211.

[0044] Specifically, there are two sets of walking tracks 3, symmetrically arranged at intervals. The walking tracks 3 are L-shaped, and each walking track 3 combines with the corresponding anti-tipping track 51 to form a Z-shaped track. The walking wheel set includes a driving wheel 22 and a driven wheel 23, which are respectively located at both ends of the walking vehicle body 21 and each corresponds to a set of walking tracks 3. The first drive unit 4 is connected to the driving wheel 22, and a drag chain 24 is also provided on one side of the walking vehicle body 21. To ensure that the first walking mechanism 2 moves smoothly on the walking track 3, there are at least two driving wheels 22 and at least two driven wheels 23.

[0045] Preferably, the first drive unit is a motor, and more preferably a three-in-one geared motor.

[0046] In the optimized implementation, the slag remover 1 is an existing slag remover, and its structure is only briefly described here. The slag remover 1 includes a slag remover arm 11, a slag remover carriage 12, a second traveling mechanism 13, and a slewing support 14. The slag remover carriage 12 is provided with a horizontal guide rail along its length and a second traveling mechanism 13 slidably connected to the horizontal guide rail. The second traveling mechanism 13 is preferably a traveling trolley, which can move along the horizontal guide rail on the slag remover carriage 12. The slag remover arm 11 is hinged to the traveling trolley by a first pin. The traveling trolley is provided with a second drive unit 15, which is preferably a hydraulic cylinder. The end of the slag remover arm 11 is hinged to the hydraulic cylinder by a second pin. The hydraulic cylinder can drive the slag remover arm 11 to swing up and down relative to the traveling trolley around the first pin shaft. Under the drive of the traveling trolley, the slag remover arm 11 moves closer to or away from the molten steel ladle 6. The slewing support 14 is located at the bottom of the muck-loading vehicle body 12. The slewing support 14 is rotatable and connected to the traveling vehicle body 21, allowing the muck-loading vehicle body 12 to swing around the slewing support 14. The bottom of the muck-loading vehicle body 12 is also equipped with guide wheels, which are located on both sides of the slewing support 14. The guide wheels can travel on the traveling vehicle body 21 to ensure the smooth rotation of the slewing support. Under the action of the second traveling mechanism 13, the second drive unit 15, and the slewing support 14, the muck-loading arm 11 can move forward and backward, and swing up and down and left and right to complete the muck-loading operation.
