Description

Technical Field

[0001] The utility model belongs to the technical field of wastewater treatment, and particularly relates to a concrete wastewater filtering and recycling device. Background Art

[0002] Concrete wastewater is mainly generated during the production, transportation and construction of concrete. Specifically, the ways in which concrete wastewater is generated include: wastewater generated during the concrete mixing process for cleaning concrete production mixing equipment; wastewater generated by concrete transport vehicles for cleaning tanks after completing their tasks; flushing water at concrete production sites; discarded concrete and wastewater generated during construction. Based on environmental protection, resource conservation and reducing water costs, it is necessary to filter and recycle concrete wastewater. In the prior art, it is necessary to use a concrete filtering and recycling device to filter concrete wastewater to filter out the particulate impurities in the concrete and then recycle the wastewater. However, since large and small particles of impurities are mixed in concrete wastewater, in order to filter out the small particle impurities in the wastewater, a finer filter screen is often used to filter the wastewater. However, since large particle impurities have a large inertia, they will impact on the finer filter screen for a long time, which will damage the filter screen, and a large amount of impurities will accumulate on the filter screen during the filtration process, and automatic cleaning cannot be achieved.
