Abstract

The invention discloses a steelmaking cooling water deslagging device which comprises a deslagging device body, a deslagging unit and a deep purification unit. A cooling water inlet is formed in the top of the deslagging device body, a cooling water outlet is formed in the side wall of the bottom of the deslagging device body, and a deep purification unit is arranged at the cooling water outlet; a plurality of groups of deslagging units are arranged in the deslagging device body, and the deslagging units are arranged layer by layer from top to bottom and are parallel to one another; the deslagging unit comprises a conveying belt with a filter screen and a conveying belt driving device; a slag storage groove is formed in the top of the high side of the conveying belt; and the hole diameters of the filter screens in each layer of deslagging unit are gradually reduced from top to bottom. According to the characteristics of the steelmaking cooling water, effective deslagging treatment can be carried out, so that the treated steelmaking cooling water better meets the discharge requirement, the environmental protection is realized, the utilization rate can be improved, and the energy reutilization is realized.

Description

technical field [0001] The invention relates to the technical field of steelmaking cooling water treatment, in particular to a steelmaking cooling water slag removal device. Background technique [0002] In the process of steelmaking production, a large amount of waste water will be produced. The waste water mainly contains the oxide scale produced on the surface of the roll table of the spray cooling mill and the rolled steel, oily substances on the mechanical equipment, solid impurities and other wastes and pollutants. Mud etc. If the waste water is discharged directly, it will not only pollute the environment, but also cause a serious waste of water resources. Therefore, each rolling mill takes certain measures to recycle water according to its own situation. At the same time, scientific researchers are also studying various new water treatment methods to improve the quality of water after treatment, reduce treatment costs, and open up new ideas for energy saving and con...
