Description

Technical Field

[0001] The utility model relates to a slag scooping system, in particular to a steel ladle hanging type slag scooping system, belonging to the technical field of slag scooping. Background Art

[0002] A large amount of slag will be generated during the metal smelting process, floating on the surface of the ladle or the smelting furnace. If the slag is not cleaned up, it will affect the quality of the molten iron and castings. There are two main ways to remove slag in the smelting industry: manual slag removal and mechanical slag removal. The emergence of mechanical slag removal breaks the traditional manual slag removal. Mechanical slag removal only requires remote control, and the slag in the furnace can be removed through the slag removal gripper. Mechanical slag removal can use various protective devices to make the working process safer and more reliable, ensuring the long-term stable operation of the smelting equipment.

[0003] However, the existing mechanical slag remover for metal smelting still has the following shortcomings in actual use:

[0004] Mechanical slag scooping machines have poor flexibility, and the slag scooping grippers can generally only be used for scooping work in a directional and fixed point when in use. They have great limitations, and the slag scooping grippers cannot grab the slag in the furnace in all directions, and dead corners are prone to occur, resulting in a lot of room for improvement in the slag scooping effect.

[0005] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

The two slag rakes are respectively fixed to the bottom of the driving shaft, and the top of the driving shaft passes through a fixed seat and is connected to a rotating motor. The fixed seat is fixed to the bottom end of the lifting arm.

[0014] Furthermore, the slag scooping actuator includes a gripper, which is hinged to the bottom of the swivel seat, and the top of the swivel seat is connected to the bottom end of the lifting arm through a swivel bearing.
