Description

technical field [0001] The invention is an automatic water adding device and a control system based on a microwave on-line moisture detector, and belongs to the technical field of sintering production in the iron and steel industry. Background technique [0002] The moisture control of sinter mixture is an important part of sinter production, which not only affects the vertical sintering speed, but also affects the yield, productivity and drum index of sinter. The moisture in the mixture is small, the sintering speed is fast, but the yield is low, the amount of ore returned is large, and the drum index decreases; the moisture in the mixture is large, the sintering speed is slow, the productivity is low, and various consumptions increase. [0003] At present, there are many manufacturers of automatic water adding system for sintering mixture, but the system is too complicated. The general system will include a belt scale. The belt speedometer is first used to detect the weigh...

The moisture in the mixture is small, the sintering speed is fast, but the yield is low, the amount of returned ore is large, and the drum index decreases; the moisture in the mixture is large, the sintering speed is slow, the productivity is low, and various consumptions increase

[0003] At present, there are many manufacturers of automatic water adding system for sintering mixture, but the system is too complicated. The general system will include a belt scale. The belt speedometer is first used to detect the weight of the material on the belt, and then adjust the sintering and mixing according to the weight of the material. Second, how much water is mixed, after the belt scale, the water adding system and the moisture detection system are often arranged. There will be fluctuations in water addition to the system, and sometimes there will be fluctuations in water addition when the working condition is very stable; and most of the current automatic water addition systems use the method of adding water at the same time as the first mixing and the second mixing. If the water adding system is installed, the system will be very complicated and the failure rate is high. What's more, when the moisture content of the material changes, the system adjustment speed is slow
