[0016] (1) The utility model can effectively solve the problem that the existing industrial wastewater filter screen is easily damaged and broken due to sudden changes in water pressure impact when filtering wastewater through the coordinated use of the diverter bucket, the diverter hole and the spring assembly. The diverter bucket can block and disperse the industrial wastewater to be filtered, so that it can be drained to the mesh body through the multi-group diverter hole for filtering, thereby reducing the scouring force generated when the wastewater contacts the filter screen, thereby facilitating the protection of the filter screen to prevent damage and breakage. At the same time, when the diverter bucket is impacted by the water flow, the slider at the bottom thereof slides along the protective ring to squeeze the spring assembly to cause it to deform, that is, the spring assembly is used for buffering, and the device is further protected thereby;

[0017] (2) The utility model can effectively solve the problem that most of the existing industrial wastewater filters are of an integrated structure, i.e., the filter screen needs to be replaced as a whole when it is damaged, which leads to high costs, by using the frame, the socket and the elastic pad in combination. When the filter screen is damaged, the staff can manually rotate the support rod to separate the top end from the funnel, then pull the bottom end of the support rod out of the socket, and then rotate the upper and lower layers of the frame in reverse, so that the screen body can be disassembled and then replaced, and the replacement process is relatively simple and convenient.
