Description

Technical Field

[0001] The utility model belongs to the technical field of waste heat recovery, and specifically relates to a material waste heat recovery device. Background Art

[0002] After the boiler is burned, a large amount of slag is generated in the production process. The slag contains a large amount of waste heat. The traditional treatment method is to spread the hot slag in a cooling area for cooling, and then put it into the coal bunker for storage. However, this cooling method not only takes up a large area, but also wastes the heat energy in the hot slag.

[0003] A Chinese patent application with application number CN202321636153.6 discloses a hot slag waste heat recovery device, which relates to the technical field of waste heat recovery devices, including a waste heat recovery box, a cooling box is arranged inside the waste heat recovery box, a pillar is arranged at the bottom of the cooling box, the cooling box is fixed to the inner bottom of the waste heat recovery box through the pillar, a feed pipe is connected to the top of the cooling box, the feed pipe extends to the outside of the waste heat recovery box at one end away from the cooling box, a stirring assembly is arranged inside the cooling box, a driving motor for driving the stirring assembly to rotate is arranged at the top of the waste heat recovery box, a discharge pipe is connected to the bottom of the cooling box, the discharge pipe extends to the outside of the waste heat recovery box, a discharge valve is installed on the discharge pipe, a spray assembly is arranged between the waste heat recovery box and the cooling box, and a drain pipe is connected to the side wall of the waste heat recovery box. The utility model not only occupies a small area, but also can recycle the heat energy in the hot slag, avoid the hot slag from generating a large amount of dust during the process of spreading cooling or stacking for transportation, and avoid the work area environment from being polluted by dust and affecting the health of the staff. However, when the above-mentioned device is actually used, the slag material will form dirt in the cooling box, and long-term use will affect the efficiency of waste heat recovery of the device. The discharge pipe at the bottom of the cooling box is not convenient for the discharge of the slag material, and the slag material will accumulate at the bottom of the cooling box. Stirring the slag material cannot make it completely fit into the cooling box, resulting in low heat conduction of the slag material.

[0004] In view of this, the present utility model is proposed. Utility Model Content
