Description

Technical Field

[0001] The utility model relates to a slag grabbing device, in particular to a slag grabbing device suitable for a blast furnace smelting slag sedimentation tank, belonging to the technical field of sedimentation tank slag grabbing. Background Art

[0002] There is an iron outlet at the bottom of the blast furnace. During the production process, molten iron and high-temperature slag are discharged from the iron outlet. The slag is cooled down after being impacted by cooling water to form a slag-water mixture. The slag-water mixture is washed into the filter tank along the slag flushing ditch. After the slag-water mixture is precipitated in the sedimentation tank for a period of time, the slag naturally settles to the bottom of the tank due to its own density. The slag on the bottom of the sedimentation tank needs to be transferred regularly, and it is grabbed out of the sedimentation tank and transferred to other locations. At present, the grabbing of the slag in the sedimentation tank is completed by the grab bucket, and the lifting equipment drives the grab bucket into the In the process, the slag rises with the pool water, that is, when the grab bucket leaves the pool surface, a large amount of water remains inside it, and the slag needs to be drained before it can be transferred to the designated location for unloading. In the actual production process, the grab bucket naturally releases water for a long time, resulting in the grab bucket staying in the air and unable to move or unload, which seriously affects the transfer efficiency of the slag in the sedimentation tank. Therefore, a grabbing device is needed, which is required to be able to efficiently transfer the slag in the sedimentation tank, thereby improving the slag transfer efficiency and reducing the operation time.
