Description

Technical Field

[0001] This utility model relates to the field of metallurgical equipment technology, and in particular to a ladle hot repair system. Background Technology

[0002] During hot repairs of steel ladles, such as removing sliding plates, cleaning residual steel, and repairing refractory materials, a large amount of high-temperature dusty fumes are generated. These fumes mainly consist of metal oxides, refractory material particles, and graphite carbon powder, with fine particle sizes and large temperature fluctuations (200-800℃). This dust not only deteriorates the working environment and affects worker health, but also accelerates the wear and tear on workshop equipment and pollutes the atmosphere through fugitive emissions.

[0003] Therefore, it is necessary to collect and treat the dust from hot repair of steel ladles. Traditional hot repair systems are fixed dust collection systems. By setting up dust collection hoods at the hot repair station, a mobile trolley transports the steel ladle to the hot repair station for hot repair dust removal. However, this method requires waiting for the previous steel ladle to be hot repaired and transported out of the hot repair station before the next steel ladle can be transported to the hot repair station, resulting in low hot repair dust removal efficiency. Utility Model Content

[0004] The main purpose of this invention is to propose a hot repair system for steel ladles, which aims to solve the problem of low dust removal efficiency in existing hot repair systems for steel ladles.

[0005] To achieve the above objectives, this utility model proposes a ladle hot repair system with at least two hot repair stations for ladle hot repair operations. The ladle hot repair system includes a dust removal hood, a movable base, and a first dust removal pipe that can be connected to external dust removal equipment. The movable base moves through each of the hot repair stations. The dust removal hood is mounted on the movable base and has a receiving cavity for the ladle to be placed horizontally. The dust removal hood is provided with a dust removal port that can be connected to the first dust removal pipe, and the dust removal port is connected to the receiving cavity.

[0006] According to some embodiments of the present invention, two dust removal ports are provided, both of which are connected to the receiving cavity. One of the dust removal ports is provided corresponding to the opening of the ladle, and the other dust removal port is provided corresponding to the bottom of the ladle.

[0007] According to some embodiments of the present invention, the first dust removal pipe is connected to two negative pressure ports, each of which is located above the corresponding hot repair station, and both dust removal ports are connected to each of the negative pressure ports.

[0008] According to some embodiments of this utility model, it also includes a second dust removal pipe, the negative pressure interface is connected to the two dust removal ports through the second dust removal pipe, and the end of the second dust removal pipe near the negative pressure interface is connected to the negative pressure interface with a clearance fit.

[0009] According to some embodiments of this utility model, the negative pressure interface is equipped with an electric valve.

[0010] According to some embodiments of the present invention, the receiving cavity has two openings in the x direction, the dust removal hood includes a top plate and a side plate corresponding to the ladle opening, one end of the side plate is connected to the movable base and the other end is connected to the top plate, the side plate and the top plate enclose the receiving cavity, and the two dust removal openings are both provided on the top plate.

[0011] According to some embodiments of the present invention, the two hot repair stations are arranged at intervals in the x direction, and the top plate of the dust removal hood is provided with baffles on both sides in the x direction, and the baffles are located between the two dust removal ports.

[0028] This utility model provides a hot repair system for steel ladles. Figures 1 to 5 This invention provides a specific embodiment of a ladle hot repair system.

[0029] like Figures 1 to 4As shown, this utility model embodiment provides a ladle hot repair system 100, which has at least two hot repair stations 1 for hot repair operations on the ladle 200. The ladle hot repair system 100 includes a dust removal hood 2, a movable base 3, and a first dust removal pipe 4 that can be connected to an external dust removal device. The movable base 3 moves through each of the hot repair stations 1. The dust removal hood 2 is disposed on the movable base 3. The dust removal hood 2 has a receiving cavity for the ladle 200 to be placed horizontally, and the dust removal hood 2 is provided with a dust removal port 211 that can be connected to the first dust removal pipe 4. The dust removal port 211 is connected to the receiving cavity.

[0030] In this utility model, the ladle hot repair system 100 has at least two hot repair stations 1. The dust removal hood 2 is installed at one of the hot repair stations 1. When a ladle 200 to be hot repaired is placed at the other hot repair station 1, the movable base 3 moves to the hot repair station 1, so that the ladle 200 to be hot repaired is placed horizontally in the receiving cavity of the dust removal hood 2. When the worker performs hot repair work on the ladle 200 to be hot repaired, the generated dust is discharged from the dust removal port 211 through the first dust removal pipe 4 to the external dust removal equipment. When the ladle 200 to be hot repaired is being hot repaired, the other ladle 200 to be hot repaired can be moved to another empty hot repair station 1. After the hot repair dust removal work is completed, the movable base 3 moves directly to the hot repair station 1. Another worker performs hot repair work on the ladle 200 to be hot repaired at the hot repair station 1 and the dust removal hood 2 removes dust. Compared with the existing method of setting a fixed dust removal hood on a single hot repair station 1 for dust removal, this utility model eliminates the need to wait for the previous ladle 200 to be hot repaired and transported out of the hot repair station 1 before transporting the next ladle 200 to the hot repair station 1 for hot repair dust removal. This saves the time of replacing the ladle 200 and greatly improves the efficiency of hot repair dust removal.

[0031] Specifically, in some embodiments, such as Figure 2 and Figure 4 As shown, each of the hot repair workstations 1 is equipped with a corresponding hot repair platform 9. The two hot repair platforms 9 are connected by a cantilever beam 10, which is used to hoist hot repair tools. Workers can stand on the hot repair platform 9 to perform hot repair operations.

[0032] Since workers mainly perform hot repairs on the ladle opening and bottom of the 200 ladle, these two areas generate the most smoke and dust. To improve dust removal efficiency, in some embodiments, such as... Figure 4As shown, there are two dust removal ports 211, both of which are connected to the receiving cavity. One dust removal port 211 is positioned at the opening of the ladle 200, and the other dust removal port 211 is positioned at the bottom of the ladle 200. This arrangement positions the two dust removal ports 211 directly at the two locations with the most smoke and dust during hot repairs, enabling more smoke and dust to be removed and improving dust removal efficiency.

[0033] In some embodiments, such as Figure 2 and Figure 4 As shown, the first dust removal pipe 4 is connected to two negative pressure ports 41. Each negative pressure port 41 is located above the corresponding hot repair station 1, and both dust removal ports 211 are connected to each negative pressure port 41. Specifically, each negative pressure port 41 is connected to a fan, which draws away the smoke and dust inside the dust removal hood 2 by creating negative pressure. Increasing the power of the fan can improve the dust removal efficiency.

[0034] Since the dust removal hood 2 needs to move back and forth between the two hot repair stations 1, while the first dust removal pipe 4 remains stationary, a rapid connection and disconnection is required between the negative pressure interface 41 and the dust removal port 211. In some embodiments, such as... Figure 3 and Figure 4 As shown, the ladle hot repair system 100 also includes a second dust removal pipe 5. The negative pressure interface 41 is connected to the two dust removal ports 211 through the second dust removal pipe 5. One end of the second dust removal pipe 5 near the negative pressure interface 41 is connected to the negative pressure interface 41 with a clearance fit. This configuration, with the second dust removal pipe 5 and the negative pressure interface 41 in a clearance fit, ensures that dust enters the negative pressure interface 41 through the dust removal port 211 and the second dust removal pipe 5. Furthermore, it eliminates the need for additional connecting parts between the second dust removal pipe 5 and the negative pressure interface 41, saving time on the disassembly and assembly of connecting parts. This shortens the time required for the dust removal hood 2 to move to the other hot repair station 1, thereby improving the hot repair dust removal efficiency of the ladle hot repair system 100.

[0035] Furthermore, in some embodiments, such as Figure 2 and Figure 4 As shown, the negative pressure port 41 is equipped with an electric valve 42. When hot repair work is performed at one of the hot repair stations 1, the electric valve 42 on the negative pressure port 41 corresponding to the hot repair station 1 is opened, and the electric valve 42 on the other negative pressure port 41 is closed to prevent smoke and dust from leaking from the other negative pressure port 41.

[0036] The specific structure of the dust collector hood 2 is not limited, as long as the steel ladle 200 can be placed inside the dust collector hood 2. For example, in some embodiments, such as... Figure 2 and Figure 4 As shown, the receiving cavity has two openings in the x-direction. The dust removal hood 2 includes a top plate 21 and side plates 22 corresponding to the opening of the ladle 200. One end of the side plate 22 is connected to the movable base 3, and the other end is connected to the top plate 21. The side plate 22 and the top plate 21 enclose the receiving cavity, and the two dust removal ports 211 are both located on the top plate 21. With this configuration, the ladle 200 can directly enter the receiving cavity of the dust removal hood 2 through the openings for placement and hot repair, reducing the steps required to enter the receiving cavity and shortening the time required for the ladle 200 to enter the receiving cavity, thereby improving the hot repair dust removal efficiency of the ladle hot repair system 100.

[0037] Furthermore, in some embodiments, such as Figure 4 As shown, the two hot repair stations 1 are spaced apart in the x-direction. The top plate 21 of the dust collector hood 2 has baffles 23 on both sides in the x-direction, with the baffles 23 located between the two dust collection ports 211. This arrangement prevents some of the smoke and dust from leaking from the openings on both sides of the receiving cavity, reducing the pollution of the workshop by smoke and dust.

[0038] In some embodiments, such as Figure 4 and Figure 5 As shown, a maintenance platform 24 is provided on the outer side of the side plate 22, and an oxygen blowing port 221 is provided on the side plate 22, with the oxygen blowing port 221 located above the maintenance platform 24. With this arrangement, since the side plate 22 is directly opposite the ladle 200 opening, and the oxygen blowing port 221 is directly opposite the ladle 200 opening, oxygen is blown into the oxygen blowing port 221, causing combustion inside the ladle 200 to melt the slag at the bottom blowing port. This prevents the slag from clogging the bottom blowing port, and workers can stand on the maintenance platform 24 to observe the melting of the slag at the bottom blowing port inside the ladle 200.

[0039] The specific method by which the ladle 200 is transported to the hot repair station 1 is not limited; for example, in some embodiments, such as... Figure 3 As shown, the ladle hot repair system 100 also includes a crane 6 and two tracks 7. The crane 6 spans across the two tracks 7 and moves on the tracks 7. The movement path of the crane 6 is located directly above the two hot repair stations 1. The crane 6 includes a hook 61 detachably connected to the ladle 200. This configuration, using the crane 6 to lift the ladle 200, requires less workshop space compared to transporting the ladle 200 via a mobile trolley, and reduces the steps of loading and unloading the ladle 200 onto the mobile trolley, thereby improving the hot repair dust removal efficiency of the ladle hot repair system 100.

[0040] Furthermore, in some embodiments, such as Figure 2 and Figure 4 As shown, two hot repair supports 8 are spaced apart on the hot repair station 1. Each hot repair support 8 has a support surface for placing the ladle 200, and the shape of the support surface is adapted to the side wall of the ladle 200. This arrangement allows the ladle 200 to be supported by the two hot repair supports 8, facilitating hot repairs on the ground-facing side of the ladle 200 by workers.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
