Description

TECHNICAL FIELD

[0001] The utility model belongs to the production technology field of semi coke, and particularly relates to a coke discharging device for semi coke production. BACKGROUND

[0002] Nowadays, the semi coke produced in the coke oven is pushed into a hopper car by a push plate and then transported to a cooling tower for rapid cooling to form a product, and the product is directly piled up outdoors for natural air drying, which is complicated and slow in water evaporation.

[0003] According to the search, the Chinese patent CN202089928U discloses a coke discharging device for semi coke production, which comprises a water tank, a coke scraping device, and first and second scraping plates.

If the heat is not recycled, a large amount of heat will be wasted. In addition, the direct contact between the semi coke and the water will generate a large thermal stress, thereby causing the product block coke to be broken into small pieces, which affects the production quality of the semi coke product.
