Technical Field
[0001] This utility model relates to the technical field of molten iron ladle cleaning equipment, specifically a cleaning device for molten iron ladle after desulfurization. Background Technology
[0002] Lime powder is usually added to molten iron ladles for dephosphorization. A small amount of molten iron, unreacted lime powder, oxides in the molten iron, and particles eroded from the refractory material of the molten iron ladle together form a complex molten or semi-molten material called dephosphorization slag. After multiple dephosphorization reactions, this slag will accumulate and adhere firmly to the ladle wall, making it difficult to remove. However, due to the different specifications of molten iron ladles, such as diameter and depth, cleaning often requires the use of cleaning equipment that matches the specific size of the ladle, which increases the complexity and cost of the operation.

[0017] 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, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Example 1: Please refer to Figure 1-2 One embodiment of this utility model provides a cleaning device for molten iron ladle after desulfurization, comprising a support frame 1, a sliding plate 2, a hydraulic cylinder 3, and a cleaning device 5. Support frame 1 is a rectangular frame symmetrically arranged on the left and right ends of the molten iron ladle. Its central axis is coaxial with the ladle, serving as the basic frame of the equipment and bearing the weight of all moving parts. The rectangular frame provides high rigidity to resist torsional loads during cleaning operations. The coaxial design of the central axis with the ladle ensures precise coverage of the ladle wall during cleaning. A sliding plate 2 is provided between the two support frames 1. The sliding plate 2 slides onto the support frame 1 and is driven by a hydraulic cylinder 3. This sliding engagement with the support frame 1 ensures stable and unbiased movement of the sliding plate 2, achieving vertical lifting and lowering motion. The cleaning device 5 is designed to move up and down, and provides a platform for the drive motor and the cleaning device 5. A hydraulic cylinder 3 is installed between the bottom end of the sliding plate 2 and the support frame 1, which pushes the sliding plate 2 to move vertically up and down along the support frame 1, adjusting the cleaning height to cover different depth areas of the molten iron ladle. The hydraulic cylinder 3 is connected to a hydraulic pump through a pipeline, and a regulating valve is installed on the pipeline. The working principle of the hydraulic cylinder 3 is existing technology and will not be described in detail in this application. The bottom end of the hydraulic cylinder 3 is connected to the support frame 1, and the top end of its piston rod is connected to the sliding plate 2. The cleaning device 5 is installed on the sliding plate 2. The cleaning device 5 includes a rotating rod 501, a first fixed collar 502, a second fixed collar 503, a threaded rod 504, a movable collar 505, an adjusting collar 506, and a cleaning plate 507. A drive motor is connected to the sliding plate 2, providing driving force to the cleaning device 5 and driving the rotating rod 501 to rotate. The output end of the drive motor passes through the sliding plate 2 and is connected to the rotating rod 501. The rotating rod 501 is coaxially arranged with the central axis of the molten iron ladle, so that each cleaning plate 507 can fit against the inner wall of the molten iron ladle. The upper and lower ends of the rotating rod 501 are respectively fixedly connected to the first fixed collar 502, the second fixed collar 503, the threaded rod 504, the movable collar 505, the adjusting collar 506, and the cleaning plate 507. Two fixed collars 503, the first fixed collar 502, and the second fixed collar 503 provide mounting bases for the connecting rod 508. When the adjusting collar 506 is manually rotated, causing the movable collar 505 to move, the movable collar 505 causes the connecting rod 508 to shift by an angle, increasing or decreasing the distance between the cleaning plates 507. At the same time, it causes the connecting rod 508 on the first fixed collar 502 and the second fixed collar 503 to shift, supporting the cleaning plates 507. The end of the rotating rod 501 away from the drive motor is coaxially connected to a threaded rod 504, on which the movable collar 505 and the adjusting collar 506 are provided. The movable collar 505 can slide axially along the threaded rod 504. The adjusting collar 506 has an internal thread and is screwed onto the threaded rod 504. The adjusting collar 506 is used to adjust the position of the movable collar 505, allowing the movable collar 505 to slide along the threaded rod 504, thereby changing the spacing between the cleaning plates 507. Several connecting rods 508 are uniformly hinged at an angle on the outer circumference of the first fixed collar 502, the second fixed collar 503, and the movable collar 505. The other end of each connecting rod 508 is hinged to the cleaning plate 507. The connecting rods 508 hinged on the movable collar 505 are connected to the first fixed collar 502, the second fixed collar 503, and the movable collar 505. The connecting rods 508 hinged on the collar 503 are symmetrical. Several obliquely arranged support feet 4 are provided at the bottom of the support frame 1 to increase the contact area between the support frame 1 and the ground and resist the horizontal reaction force when the equipment is operating. The oblique layout enhances the overall stability of the device. Several cleaning blocks are provided on the cleaning plate 507. The cleaning blocks abut against the inner wall of the molten iron ladle. When the cleaning device 5 rotates and moves up and down driven by the hydraulic cylinder 3, the cleaning blocks clean and remove the deposits on the inner wall of the molten iron ladle. A limit block is provided at the end of the threaded rod 504 away from the rotating rod 501 to limit the maximum movement position of the adjusting collar 506.
[0019] In use, the hydraulic cylinder 3 first drives the sliding plate 2 to rise, and the bottom of the cleaning device 5 is located at the top of the molten iron ladle. Then, the adjusting collar 506 is rotated to move the movable collar 505. When the movable collar 505 moves, the distance between it and the second fixed collar 503 is reduced or increased, which causes the connecting rod 508 on the movable collar 505 to shift, thereby increasing or decreasing the distance between the cleaning plates 507, so that the cleaning blocks fit and contact the inner wall of the molten iron ladle. Then, the hydraulic cylinder 3 drives the cleaning device 5 to move up and down, and at the same time, the drive motor is started to drive the rotating rod 501 to rotate, cleaning and removing the deposits on the inner wall of the molten iron ladle.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model.
