[0035] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0036] In addition, this application may repeat reference numbers and / or reference letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials, but those of ordinary skill in the art will recognize the application of other processes and / or the use of other materials.

[0037] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0038] See also Figures 1 to 4 The embodiment of the present application proposes a dust removal device 10, which is suitable for removing dust from a ladle 40 that is being cold-repaired at a ladle cold-repair position 50. Figure 1 The dust removal device 10 includes a frame 100, a dust collecting pipe 200 and a dust collector 300, wherein the frame 100 is arranged on one side of the ladle cold repair position 50, the frame 100 is the track bracket 30 of the overhead crane 20 in the ladle cold repair workshop, and the dust collecting pipe 200 is movably arranged on the frame 100 in the horizontal direction so that the inlet of the dust collecting pipe 200 can be switched between the above the ladle cold repair position 50 and the avoidance position, and the outlet of the dust collecting pipe 200 is connected to the inlet of the dust collector 300.

[0039] Cold servicing of the ladle 40 involves repairing or replacing the lining material after a certain number of uses due to wear or damage. This process typically involves inspecting, removing, cleaning, and rebuilding or replacing the lining material. The purpose of cold servicing is to ensure the ladle 40 can continue to be used safely and efficiently, while also extending its service life.

[0040] The ladle cold repair station 50 is located within the ladle cold repair workshop, which is used to perform cold repairs on ladles 40. The ladle 40 to be cold repaired is secured to the ladle cold repair station 50, typically with its opening facing horizontally, to facilitate cold repair. However, the cold repair process of the ladle 40 generates a large amount of smoke and dust, which impacts the environment. To reduce environmental pollution and meet higher environmental protection requirements, a dust removal device 10 is installed at the ladle cold repair station 50 in the ladle cold repair workshop.

[0041] The frame 100 in the embodiment of the present application provides an installation base for the dust collecting pipe 200, so that the dust collecting pipe 200 can be installed on the frame 100 to achieve the installation of the dust collecting pipe 200 in the dust removal device 10. The dust collector 300 draws smoke and dust into the interior from the inlet through negative pressure, and then discharges the purified airflow from the outlet to achieve the dust removal effect. The inlet of the dust collecting pipe 200 is set above the ladle cold repair position 50, so that the outlet of the dust collecting pipe 200 is connected to the inlet of the dust collector 300 to form a negative pressure in the dust collecting pipe 200. Under the action of the negative pressure, the smoke and dust in the ladle cold repair position 50 enter the dust collecting pipe 200 from the inlet of the dust collecting pipe 200, and then enter the dust collector 300 for dust removal and purification.

[0042] Furthermore, within a ladle cold repair workshop, an overhead crane 20 is typically used to move the ladle 40. The overhead crane 20 moves the ladle 40 to be cold repaired to the ladle cold repair position 50, and the overhead crane 20 moves the ladle 40 after cold repair out of the ladle cold repair position 50. The overhead crane 20 moves the ladle 40 in both horizontal and vertical directions. That is, the ladle cold repair position 50 is located within the operating area of the overhead crane 20. Since the dust removal device 10 proposed in the embodiment of the present application is a modification of the dust removal system of the ladle cold repair workshop and is part of the dust removal system of the ladle cold repair workshop, the frame 100 of the dust removal device 10 proposed in the embodiment of the present application is essentially the track support 30 of the overhead crane 20. The overhead crane 20 has two track supports 30 spaced apart, and the ladle cold repair position 50 is located between the two track supports 30. Tracks are provided on the tops of the two track supports 30, and the main body of the overhead crane 20 operates on the tracks on the tops of the two track supports 30, thereby reducing construction cost and difficulty.

[0043] Since placing the dust collecting pipe 200 at the ladle cold repair position 50 would affect the installation of the ladle 40 at the ladle cold repair position 50, the dust collecting pipe 200 is arranged on the frame 100 so as to be movable in the horizontal direction. By translating the dust collecting pipe 200, the inlet of the dust collecting pipe 200 can be switched between above the ladle cold repair position 50 and an avoidance position. It should be noted that the avoidance position is an area outside the ladle cold repair position 50, which allows the dust collecting pipe 200 to avoid the ladle 40. When the ladle 40 needs to be cold repaired, the dust collecting pipe 200 is moved to an area outside the ladle cold repair position 50 to avoid interfering with the installation of the ladle 40 at the ladle cold repair position 50. When the ladle 40 is installed in the ladle cold repair station 50, the dust collecting pipe 200 is moved into the ladle cold repair station 50, so that the inlet of the dust collecting pipe 200 is located above the ladle cold repair station 50, so as to remove dust from the ladle 40 being cold repaired in the ladle cold repair station 50. This reduces pollution to the environment and meets higher environmental protection requirements.

[0044] In some embodiments, as Figure 1 as well as Figure 2As shown, the dust removal device 10 further includes a fixed frame 400. The fixed frame 400 is generally U-shaped and has a first end and a second end opposite to each other. The first end of the fixed frame 400 is movably connected to the frame 100, and the second end of the fixed frame 400 is switchably positioned above the ladle cold repair station 50. The dust collecting pipe 200 is disposed within the fixed frame 400, and the inlet end of the dust collecting pipe 200 is correspondingly disposed to the second end of the fixed frame 400. The frame 100 is disposed on one side of the ladle cold repair station 50. When the ladle 40 is mounted on the ladle cold repair station 50, the opening of the ladle 40 is generally facing away from the frame 100, and the bottom of the ladle 40 is generally facing the frame 100. Therefore, when the ladle 40 is cold-repaired, since the smoke and dust mainly come from the opening of the ladle 40, that is, the ladle cold-repair position 50 is far away from the frame 100, the dust collecting pipe 200 is suspended on the frame 100 through the fixed frame 400, so that the entrance of the dust collecting pipe 200 is located above the opening of the ladle 40.

[0045] In some embodiments, the dust collecting tube 200 and the fixing frame 400 may be connected by welding, screwing, clamping, or the like, which is not limited in this embodiment of the present application.

[0046] In some embodiments, as Figure 1 as well as Figure 3 As shown, the frame 100 is provided with a running rail 110, which is arranged in a horizontal direction, with the rail surface of the running rail 110 facing upward. The bottom of the first end of the fixed frame 400 is provided with a running wheel 410, and the running wheel 410 is rollably arranged on the running rail 110. By providing the running rail 110 on the frame 100 and the running wheel 410 at the bottom of the first end of the fixed frame 400, the running wheel 410 of the fixed frame 400 is rollably arranged on the running rail 110, thereby achieving a movable connection between the fixed frame 400 and the frame 100, and thus achieving a dust collection tube 200 that can be movably arranged on the frame 100 in the horizontal direction.

[0047] In some embodiments, as Figure 3As shown, the frame 100 is further provided with an upper support rail 120 and a lower support rail 130. The upper support rail 120 and the lower support rail 130 are arranged in a horizontal direction, with the rail surface of the upper support rail 120 facing away from the ladle cold repair position 50, and the rail surface of the lower support rail 130 facing the ladle cold repair position 50. The fixed frame 400 is further provided with an upper support wheel 420 and a lower support wheel 430. The upper support wheel 420 is provided at the top of the first end of the fixed frame 400 and is rollably mounted on the upper support rail 120. The lower support wheel 430 is provided at the bottom of the first end of the fixed frame 400 and is rollably mounted on the lower support rail 130. Since the fixed frame 400 is suspended on the frame 100, in order to improve the support effect of the frame 100 on the fixed frame 400. Therefore, an upper support rail 120 and a lower support rail 130 are provided on the frame 100, and an upper support wheel 420 and a lower support wheel 430 are provided on the fixed frame 400, and the rail surface of the upper support rail 120 is directed away from the ladle cold repair position 50, and the rail surface of the lower support rail 130 is directed toward the ladle cold repair position 50, so as to improve the supporting effect of the frame 100 on the fixed frame 400 while ensuring the movable connection effect between the fixed frame 400 and the frame 100.

[0048] In some embodiments, as Figure 1 As shown, the frame 100 is further provided with an upper support arm 140 and a lower support arm 150. An upper mounting beam 160 is provided on the upper support arm 140, and a lower mounting beam 170 is provided on the lower support arm 150. The upper support rail 120 is provided on the upper mounting beam 160, and the running rail 110 and the lower support rail 130 are both provided on the lower mounting beam 170. By providing the upper support arm 140 and the lower support arm 150 on the frame 100, and providing the upper mounting beam 160 on the upper support arm 140 and the lower mounting beam 170 on the lower support arm 150, the upper support rail 120 is provided on the surface of the upper mounting beam 160 facing away from the ladle cold repair station 50, and the running rail 110 and the lower support rail 130 are provided on the upwardly facing surface and the surface of the lower mounting beam 170 facing the ladle cold repair station 50, respectively, thereby achieving a stable arrangement of the upper support rail 120, the running rail 110, and the lower support rail 130 on the frame 100.

[0049] In some embodiments, as Figure 1 as well as Figure 4As shown, the fixing frame 400 is further provided with an upper wheel seat 440, a first lower wheel seat 450, and a second lower wheel seat 460. The upper wheel seat 440 is provided at the top of the first end of the fixing frame 400, the upper support wheel 420 is provided on the upper wheel seat 440, the first lower wheel seat 450 and the second lower wheel seat 460 are both provided at the bottom of the second end of the fixing frame 400, the running wheel 410 is provided on the first lower wheel seat 450, and the lower support wheel 430 is provided on the second lower wheel seat 460. By providing the upper wheel seat 440, the first lower wheel seat 450, and the second lower wheel seat 460 on the fixing frame 400, the upper support wheel 420 is provided on the upper wheel seat 440, the running wheel 410 is provided on the first lower wheel seat 450, and the lower support wheel 430 is provided on the second lower wheel seat 460, thereby achieving the arrangement of the upper support wheel 420, the running wheel 410, and the lower support wheel 430 on the fixing frame 400. In addition, to ensure the installation effect, the upper wheel seat 440 and the second lower wheel seat 460 are arranged in the vertical direction, the upper support wheel 420 is arranged on the surface of the upper wheel seat 440 facing the ladle cold repair position 50, and the lower support wheel 430 is arranged on the surface of the second lower wheel seat 460 facing away from the ladle cold repair position 50. The first lower wheel seat 450 is arranged in the horizontal direction, and the travel wheel 410 is arranged on the surface of the first lower wheel seat 450 facing downward.

[0050] In some embodiments, as Figure 1 as well as Figure 2 As shown, the dust removal device 10 further includes a dust removal pipe 470, which is provided on the frame 100. The outlet of the dust removal pipe 470 is connected to the inlet of the dust collector 300. The outlet of the dust collecting pipe 200 and the inlet of the dust removal pipe 470 are switchably arranged to correspond to each other, and the inlet of the dust removal pipe 470 is arranged to correspond to the ladle cold repair position 50. Since the dust removal pipe 470 is provided on the frame 100 and the inlet of the dust removal pipe 470 is arranged to correspond to the ladle cold repair position 50, when the dust collecting pipe 200 is moved above the ladle cold repair position 50, the outlet of the dust collecting pipe 200 is arranged to correspond to the inlet of the dust removal pipe 470, thereby achieving communication between the outlet of the dust collecting pipe 200 and the inlet of the dust collector 300 through the dust removal pipe 470.

[0051] In some embodiments, as Figure 1 as well as Figure 2 As shown, the outlet of the dust collecting pipe 200 is arranged at the top of the dust collecting pipe 200, and the inlet of the dust removal pipe 470 is arranged downward. When the dust collecting pipe 200 is moved above the ladle cold repair position 50, the outlet of the dust collecting pipe 200 and the inlet of the dust removal pipe 470 are conveniently arranged correspondingly.

[0052] In some embodiments, as Figure 2As shown, the dust removal pipe 470 has multiple inlets, and the outlet of the dust collection pipe 200 is switchably arranged to correspond to the multiple inlets of the dust removal pipe 470. Multiple ladle cold repair positions 50 are provided in the ladle cold repair workshop, and each inlet of the dust removal pipe 470 corresponds to a ladle cold repair position 50. When dust removal is required for a ladle 40 at one of the ladle cold repair positions 50 in the ladle cold repair workshop, the dust collection pipe 200 is moved to the corresponding ladle cold repair position 50 for dust removal.
