[0002] During the production process of blast furnaces, a large amount of slag is produced, which is often accompanied by a large amount of waste heat. According to technical data, this part of waste heat resources accounts for more than 17% of its fuel consumption, which shows that there is a huge potential for the utilization of slag waste heat. The utilization of slag waste heat can not only reduce the energy consumption per unit product, but also reduce environmental pollution. Therefore, the utilization of slag waste heat has considerable economic and social benefits.

When the slag pressing structure 7 is raised and lowered inside the main body 1 to press the slag, the rising slag pressing plate 9 contacts the buffer seat 17 to contact and buffer the slag pressing plate 9. After the slag body and waste heat are recovered, the vibration mechanism 8 drives the guide plate 4 to vibrate, and the slag body is discharged from the discharge port 3.

The recovery structure 6 includes a fixedly connected recovery pipe 14 and a recovery pipe 16 at the bottom thereof. A filter plate 15 is embedded in the interior of the recovery pipe 14, and a buffer seat 17 is fixedly connected to the bottom surface of the recovery pipe 14. The recovery pipe 16 is vertically embedded in the surface of the top plate 5 and is located at the upper position inside the main body 1. The guide plate 4 is arranged in an "L" shape as a whole, and a section close to the feed inlet 2 is arranged in an inclined manner. The vibration mechanism 8 includes a vibration head in contact with the bottom surface of the guide plate 4 and a control mechanism. The top plate 5 is arranged in a "Z" shape as a whole. The guide plate 4 cooperates with the vibration mechanism 8 on the bottom surface to achieve the effect of facilitating the guiding and later vibration export of the slag. The top plate 5 is used to facilitate the connection and installation of the recovery structure 6 and the main body 1.

[0030] After the slag is recovered from the waste heat and compressed inside the main body 1 , the vibration mechanism 8 is started to drive the guide plate 4 to vibrate, and the slag that has been compressed is vibrated and discharged to the outside through the discharge port 3 .

[0031] The slag pressing plate 9 is arranged horizontally as a whole, and is located at the upper position inside the main body 1, and is also located directly below the recovery structure 6. The connecting frame 10 is arranged vertically in a "Z" shape as a whole, and the top is connected to the bottom surface of the slag pressing plate 9.

[0035] The slag enters the main body 1, and after being crushed and concentrated by the slag pressing structure 7, the heat therein is concentrated inside the main body 1.
