[0002] At present, wet slag scooping machines mainly use water cooling, which makes the high-temperature slag fall directly into the water, and then is scooped out for transportation. This process will generate a large amount of wastewater and waste water resources. In addition, the transmission parts of the equipment will be soaked in water for a long time, which will shorten their service life. In addition, the economic benefits of the waste slag that has been soaked in water are extremely low.

[0003] In the related art, a Chinese patent with announcement number CN113154418B discloses an implementation method for transforming a wet slag dredger system into a dry slag discharge system. The implementation method includes transforming a slag dredger into a dry slag dredger to change the wet cooling method of the slag in water into the dry cooling method of the slag through a heat exchange interlayer. The dry slag machine includes a slag trough, a heat exchange interlayer arranged at the bottom and wall of the slag trough, and a transmission mechanism with a scraper. A heat exchange tube assembly is arranged in the heat exchange interlayer, and the top surface of the heat exchange tube assembly is against the bottom surface of the bottom of the slag trough. A refrigerant is introduced into the heat exchange tube assembly. When working, the scraper is against the bottom of the slag trough and moves forward to transport the slag. An adjustable air cooling system is arranged on the wall of the slag trough.

[0004] With regard to the above-mentioned related technologies, there is a problem of uneven cooling of the slag, where small pieces of slag are deposited in the slag trough and cool faster, while large pieces of slag have a small contact area with the inner wall of the slag trough and cannot be fully cooled.
