[0025] When the utility model is in use, sewage is added into the box body 1 from the upper inlet tube 2, and the hollow mesh belt 11 is controlled to rotate. At the same time, the rotating rod 14 rotates, and the rotating rod 14 drives the receiving plate 15 to rotate. The receiving plate 15 receives the sewage during the rotation process, so as to prevent the sewage from falling directly on the hollow mesh belt 11 due to gravity, causing damage to the hollow mesh belt 11. During the rotation of the hollow mesh belt 11, the sewage can fall from the hollow mesh belt 11 to the lower outlet tube 4, and the sand and gravel in the sewage are retained in the hollow mesh belt 11. As the hollow mesh belt 11 rotates to one end of the storage box 7, it falls into the storage box 7 under the scraping action of the bonding plate 18. The storage box 7 is used to store the sand and gravel, which is simple and convenient. Moreover, since the storage box 7 is detachable, it is easy to clean.
