Description

Water quenching coke or falling material drying apparatus

Technical Field

The utility model belongs to the technical field of blast furnace feed equipment technique and specifically relates to a water quenching coke or fall to ground material drying apparatus.

Background

The blast furnace process of the iron and steel enterprises can meet the situation of draft coke quenching or floor machine burning in winter. Because the water content of water quenching coke, floor type mechanical burning, pelletizing and lump ore is large in winter, powder containing small particles is adhered to large-particle-level raw materials, the screening amount is greatly reduced, the powder containing in the furnace is increased, and the condition of the furnace is deteriorated to influence smooth operation. And secondly, because the temperature of the raw fuel is low and the water content is increased in winter, the temperature of the top in the blast furnace is low after the raw fuel is fed into the blast furnace, the next procedure production is influenced, the blast furnace is limited to be intensively smelted, and the generated energy is reduced due to the low temperature of coal gas. Generally, materials are dehumidified first, however, because the materials are heated by a rotary hearth in the traditional method for dehumidifying materials, the stacking type heating and dehumidifying mode has a long production period and high cost, and the following phenomena are easy to occur due to improper operation: 1. the dust is bonded with the material, and the material cannot be separated from the dust, so that the cleanliness of the material is poor; 2. the materials are dried, and the particles are dispersed and easily subjected to magnetic separation, so that iron and the materials are easily separated; 3. the material is moist, blocks up the screen cloth mesh of next screening process easily to increase the material screening degree of difficulty.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a water quenching or fall to ground material drying apparatus is provided, improve into the stove temperature, improve screening efficiency, the extension contact time of being convenient for improves the heating efficiency to the material, reduces the powder and goes into the stove, improves the top temperature and for the blast furnace in the same direction as going in winter, reinforces the smelting, for increasing the generated energy and providing the support, is favorable to reducing consumption and carries out the product.
