NOVELTY - The utility model claims a graphene ultra-filtration membrane filtering device, comprising a filtering tank and a processing cylinder; the inner wall of the filtering tank is fixedly welded with a limiting block; the inner circumference of the limiting block is provided with a filtering mechanism; the top part and the bottom part of the filtering tank are respectively provided with a liquid inlet pipe and a liquid outlet pipe; the bottom of the filter box and the processing cylinder are fixedly welded with four groups of supporting legs; the bottom of the supporting leg welded at the bottom of the filter box is fixedly welded with the top of the processing cylinder; the processing cylinder is a double-layer structure; the inner circumference of the processing cylinder cavity is provided with a cleaning mechanism; the inner circumference of the processing cylinder is provided with an ultra-filtration membrane main body; the inner part of the processing cylinder is divided into a muddy water chamber and a clear water chamber from inside to outside by the ultrafiltration membrane main body; the bottom of the processing cylinder is provided with a muddy water pipe connected with the muddy water chamber and a clear water pipe connected with the clean water chamber. The graphene ultra-filtration membrane filtering device can improve the processing efficiency; at the same time, it can reduce the possibility of blocking the ultra-filtration membrane main body.
