Description

TECHNICAL FIELD

[0001] The utility model relates to metallurgical slag supporting treatment equipment technical field especially a kind of ladle turning device for metallurgical slag slow cooling process. BACKGROUND

[0002] In the smelting process of metallurgical industry, a large amount of high-temperature liquid metallurgical slag is generated every year. The current treatment methods for these high-temperature liquid metallurgical slag include hot splashing method, hot fuming method, drum method, water quenching method, air quenching method and slow cooling method. For the slow cooling process used in slag yard, a slag ladle tilting device is needed to tilt and pour slag. During the transfer process of metallurgical slag, crystallization may occur. To ensure that the crystallized metallurgical slag can be completely tilted, the slag ladle tilting device is required to have a large tilting angle and high pouring position. Therefore, the slag ladle tilting process is crucial in the slag yard operation.

[0003] However, the conventional method relies on heavy cranes to accurately lift the hot slag ladle near the tilting device, and then adjusts the clamps on the tilting device to cooperate with the slag ladle to achieve the slag ladle tilting operation. However, due to the physical limitations of the length of the slag ladle trunnion, the crane hook and the clamp on the tilting device are prone to interference during the approach. This not only limits the realization of automatic operation, but also forces the operator to manually clamp in the high-temperature and high-risk operating environment, greatly increasing the risk of safety accidents. The accuracy and efficiency of manual operation are also difficult to guarantee, resulting in uneven clamping quality and further exacerbating the uncertainty in the production process.

[0004] For the existing partial automatic clamping mechanism, the complex mechanical mechanism not only increases the maintenance difficulty, and the internal precision electronic wire harness and key components are also easily damaged in the continuous high-temperature furnace slag environment, resulting in frequent failures in the field operation, affecting production efficiency and safety. Once the structure design of the tilting device or the slag ladle needs to be adjusted to adapt to new production needs, the existing automatic clamping mechanism often needs to go through a tedious redesign, precision machining and complex installation and debugging process. This series of links not only consumes a lot of capital, but also consumes a lot of time and effort, which seriously restricts the flexibility and market competitiveness of enterprises.

[0025] like Figures 1 to 6 As shown, an embodiment of a ladle-turning device for a slow cooling process of metallurgical slag includes a control device, a support 100, a tilting mechanism 200, a first drive unit 300, and a moving platform mechanism 500. The tilting mechanism 200 is hinged to the support 100, which is fixed to a base 400. One end of the first drive unit 300 is hinged to the tilting mechanism 200, and the other end is hinged to the support 100. The control device connects the first drive unit 300 and the moving platform mechanism 500, which is hinged to the support 100. The control device can drive the moving platform mechanism 500 to rotate the slag ladle 600 smoothly around the hinge point of the tilting mechanism 500, causing the slag ladle 600 to move towards the tilting mechanism 200 until the slag ladle 600 aligns with the tilting mechanism 200. The first drive unit 300 then drives the tilting mechanism 200 to flip the slag ladle 600. The tilting mechanism 200 is interchangeably hinged to the support 100 to accommodate slag pots 600 of different sizes. The first drive unit 300 includes, but is not limited to, a hydraulic push rod.

[0026] In use, the mobile platform mechanism 500 is adjusted to the initial position by the control device, the ladle 600 is hoisted onto the mobile platform mechanism 500 by the travelling crane, the hook of the travelling crane is detached from the trunnion of the ladle 600, and the ladle 600 is placed on the mobile platform mechanism. The first driving part 300 is driven by the control device to drive the tilting mechanism 200 to rotate to the direction of the ladle 600 by a predetermined angle, and then the mobile platform mechanism 500 is controlled by the control device to rotate around the hinge to the direction close to the tilting mechanism 200, so that the ladle 600 moves to the tilting mechanism 200 until the ladle 600 is connected with the tilting mechanism 200. Further, the first driving part 300 is controlled by the control device to drive the tilting mechanism 200 to rotate around the hinge to the direction away from the mobile platform mechanism 500 to the limit angle, so that the ladle 600 is tilted to the limit angle, and the ladle 600 is completely emptied. After the ladle 600 is emptied, the first driving part 300 is controlled by the control device to drive the tilting mechanism 200 to rotate to the direction close to the mobile platform mechanism 500 with the ladle 600, until the bottom of the ladle 600 is completely connected with the top of the mobile platform mechanism 500, and the mobile platform mechanism 500 is controlled by the control device to drive the ladle 600 to move away from the tilting mechanism 200, so that the ladle 600 returns to the initial position. Finally, the ladle 600 is hoisted away from the mobile platform mechanism 500 by the travelling crane. In this way, the automatic clamping and tilting of the ladle 600 are realized without manual intervention, the production efficiency is improved, the safety risk in the production process is reduced, and the interference between the hook of the travelling crane and the tilting mechanism is avoided.

[0027] It should be noted that, in the tilting process, the tilting mechanism 200 is tilted to the limit angle away from the mobile platform mechanism 500, and at this time, the first driving part 300 is also at the maximum stroke, so that the ladle 600 does not tilt too much or fall off during the tilting process, and the safety accident is avoided. At the same time, the ladle 600 does not separate from the tilting mechanism 200 due to the back force of the solid slag during the tilting process, and the ladle 600 is always on the tilting mechanism 200 during the tilting process, so that the safety and reliability of the tilting process are improved.

[0028] In an embodiment, the mobile platform mechanism 500 includes a platform 510, a second driving part 520, and a plurality of support columns 530. One end of the support column 530 is hinged to the bottom of the platform 510, and the other end of the support column 530 is hinged to the support part 100. One end of the second driving part 520 is hinged to the bottom of the platform 510 at a certain angle, and the other end of the second driving part 520 is hinged to the support part 100.

The second driving part 520 includes but is not limited to a hydraulic rod, and the second driving part 520 is connected with the control device.

[0029] In use, the control device controls the extension of the telescopic portion of the second driving portion 520, and further drives the platform 510 to move obliquely upward until the support column 530 is perpendicular to the platform 510, at which time the locking state is reached. At this time, the slag pot 600 is lifted onto the platform 510 by the travelling crane, and the second driving portion 510 and the support column 530 can effectively provide support to reduce the risk of the slag pot 600 being tilted when being lowered. When the slag pot 600 needs to be docked with the mobile platform mechanism 500, the telescopic portion of the second driving portion 520 needs to be retracted by the control device, so that the support column 530 rotates around the hinge, and the slag pot 600 gently moves obliquely downward until it is docked with the tilting mechanism 200.

[0030] In an embodiment, the tilting mechanism 200 includes a first tilting portion 210 and a second tilting portion 220 for docking the slag pot, and the first tilting portion 210 and the second tilting portion 220 are symmetrically hinged to the support portion 100. The first tilting portion 210 and the second tilting portion 220 are structurally identical. The end of each of the first tilting portion 210 and the second tilting portion 220 is provided with an ear-shaped groove 211 for docking with the ear shaft of the slag pot. The two first driving portions 300 are symmetrically arranged, respectively connected to the first tilting portion 210 and the second tilting portion 220, and the first tilting portion 210 and the second tilting portion 220 are detachably hinged to the support portion 100 to adapt to different specifications of the slag pot.

[0031] In use, the first driving portion 300 drives the first tilting portion 210 and the second tilting portion 220 to rotate synchronously, and when the first tilting portion 210 and the second tilting portion 220 are tilted to the limit angle, the first driving portion 300 is located at the maximum stroke.

[0032] In an embodiment, the tilting mechanism 200 further includes an abutting portion 230, one end of the abutting portion 230 is fixedly connected to the first tilting portion 210, and the other end of the abutting portion 230 is fixedly connected to the second tilting portion 220, so as to improve the overall structural strength of the first tilting portion 210 and the second tilting portion 220. The abutting portion 230 also abuts against the outer wall of the slag pot 600 during the ladle tilting process, i.e. the abutting portion 230 is attached to the outer wall of the slag pot 600, and can provide a certain supporting effect when the slag pot 600 is tilted.

[0033] In an embodiment, the support portion 100 includes two support frames 110, the support frames 110 are symmetrically fixed to the base 400, and the support frames 110 are fixedly connected by a plurality of cross beams 120, and the two sides of the support frames 110 close to the bottom are each provided with a plurality of rib plates 130 to sufficiently improve the structural strength between the support frames 110.

[0034] Therefore, the present application can effectively avoid the interference between the driving hook and the tilting mechanism, and can efficiently and accurately complete the automatic clamping and tilting of the slag ladle without manual intervention, thereby effectively reducing the accident risk in the production process.
