Background
In the production process of steel mills, a large amount of waste water is generated, and the direct discharge of the waste water pollutes the environment, so that the treatment of the sewage of the steel mills is required. The sewage treatment plant used in steel mills needs to filter waste such as sludge and solid impurities in sewage and also needs to recover steel particles in sewage in consideration of energy conservation.
Patent No. CN205974017U proposes a sewage treatment device to strengthen the filtering effect by multi-layer filtering holes and gradually reducing the filtering holes, but this way makes the steel particles with different volumes filtered in the filtering net difficult to recover, and needs to be cleaned frequently or the filtering effect becomes poor, which is not suitable for steel works.
In addition, patent number CN206204022U proposes a sewage filtering barrel, which performs filtering treatment on sewage by a multi-layer screen, but sewage treatment equipment needs to continuously treat sewage in a long-time production process, waste is accumulated on a filtering net and is difficult to remove, and the filtering effect is poor for a long time.
In addition, patent number CN206597356U provides a sewage treatment device, through two-layer structure about the detachable, the opening device of being convenient for gets rid of the waste material of filter screen, but the filterable sewage waste material is more at the steel mill, needs frequent opening device to clean, has not only produced a large amount of labours and time consumption, still can influence the live time of device.
The above-mentioned conventional apparatuses not only have various problems to be treated, but also have a problem that iron and steel particles cannot be effectively recovered, and the purpose of energy saving cannot be achieved, so that an apparatus for treating sewage of a steel mill is urgently needed.
