Description

Technical Field

[0001] The utility model relates to the technical field of blast furnace ironmaking, in particular to a blast furnace slag bin slag water recovery device. Background Art

[0002] Iron and steel enterprises usually use the INBA process for slag treatment. When the red slag passes through the blowing box, it will be blown and granulated by the high-pressure water sprayed from the blowing box to form a slag-water mixture, i.e., blast furnace slag; then, the slag-water mixture enters the slag-water bucket, and then flows to the drum equipment through the distributor and buffer tank. After the slag enters the drum system for dehydration, most of the slag is transported to the finished product tank by the conveyor belt, a small part of the slag enters the water collection tank, and is transported back to the slag-water bucket by the underflow pump, and then dehydrated again by the drum system, and another small part of the slag flows into the hot water pool through the overflow tank, and then is transported to the cold water pool by the cooling pump, and then is transported to the blowing box by the granulation pump, and so on.

[0003] The water slag entering the finished product tank needs to be placed for 20 minutes for dehydration. At this time, the water in the water slag will be filtered out from the filter screen of the finished product tank and transported to the return water tank through the pipeline. The slag discharge port of the finished product tank is located at the bottom of the finished product tank. The belt on the pneumatic push rod is driven to open by the pneumatic push rod to open the slag discharge port and realize slag discharge. When discharging slag, there is usually a corresponding transport vehicle under the slag discharge port to collect slag water. After the slag discharge is completed, the slag discharge port is closed and the corresponding transport vehicle leaves. However, during the on-site production process, when the slag discharge port is closed, a small amount of slag water will still flow out of the leather cover and fall directly to the ground, which not only pollutes the environment, but also causes waste of water and blast furnace slag. The water in the slag water cannot be recycled and reused.

[0004] In view of the above problems, it is urgent to find a process to solve the problem of slag water falling to the ground, so as to completely solve the problem of environmental pollution and increased labor intensity of personnel when slag water falls to the ground. Summary of the invention
