[0002] Mixing stations are mainly used in concrete construction projects. Their main purpose is to mix concrete. They are also called concrete mixing stations. Commercial concrete mixing stations are used to deliver the mixed concrete to the construction unit via a special concrete mixer truck for concrete construction.

[0003] In the existing technology, when recycling concrete wastewater, large particles in the wastewater are filtered out, while small particles still remain in the wastewater, which requires secondary filtration of the wastewater. At the same time, it is inconvenient to clean the filter net that has been used for a long time, which may cause the filter net to become blocked, and finally lead to low wastewater recovery efficiency. For this reason, we propose a wastewater recycling device for commercial concrete mixing station. Utility Model Content
