[0018] Cooling water tank 5 has a cooling water circulation outlet pipe 1, a cooling water circulation return pipe 3, an exhaust pipe 7, and a sewage discharge pipe 17 connected to it. Both the cooling water circulation outlet pipe 1 and the cooling water circulation return pipe 3 are connected to cooling equipment 18. A valve 2 is installed on the cooling water circulation outlet pipe 1, a valve 4 is installed on the cooling water circulation return pipe 3, and a sewage discharge valve 16 is installed on the sewage discharge pipe. On pipe 17, exhaust valve 6 is installed on exhaust pipe 7. The other end of sewage pipe 17 is connected to sewage well 15. Sewage pipe 17 is also connected to water outlet pipe 10. Water outlet pipe 10 is equipped with water meter 12, self-priming water pump 8, and water outlet valve 11. The other end of water outlet pipe 10 is connected to automatic water tank 13. The other end of exhaust pipe 7 is connected to water outlet pipe 10. Self-priming water pump 8 and water outlet valve 11 are both electrically connected to PLC controller 9. Automatic water tank 13 is connected to mixer 14. The wastewater from cooling water tank 5 is discharged sequentially through water meter 12, water outlet pipe 10, and water outlet valve 11 into automatic water tank 13 and mixer 14 by self-priming water pump 8. The wastewater from cooling water tank 5 is used in the mixing of materials in sintering mixer, which can not only reduce the amount of wastewater treated and save treatment costs, but also use wastewater to produce granulation and reduce the consumption of fresh water. Water meter 12 is installed on the outlet pipe 10 between the self-priming water pump 8 and the cooling water pool 5, which can determine the amount of wastewater used in the sintering mixing system.
