The filter assembly includes two symmetrically arranged filter cartridges 7, and the filter cartridges 7 are respectively arranged on both sides of the overflow port 15. By closely arranging the filter cartridges 7 on both sides of the overflow port 15, impurities can be blocked and filtered, and some large-particle impurities can be prevented from overflowing into the next sedimentation area, thereby accelerating the sedimentation rate of solid impurities and improving the filtering effect. By filtering in sequence through multiple levels of partitions 14 and filter cartridges 7, the degree of clogging of the filter cartridge 7 at the overflow port 15 can be reduced.

[0029] Furthermore, the glass fiber reinforced plastic sewage filtering device of the utility model which is not easy to be blocked also includes a plurality of flipping mechanisms arranged at the upper end of the box body 1, the flipping mechanism is arranged above the partition 14, the flipping mechanism includes a bearing seat 2, a rotating shaft 4, a gear 5 and a connecting rod 6, two bearing seats 2 are arranged horizontally at the upper end of the box body 1 along the width direction, two rotating shafts 4 are arranged horizontally in the two bearing seats 2, and gears 5 that are meshed and connected to each other are arranged on the two rotating shafts 4. That is, two gears 5 are symmetrically arranged on each rotating shaft 4, and there are four gears 5 on the two rotating shafts 4 in total. A ferrule 51 is extended and arranged on one side of the gear 5, and the ferrule 51 is fitted on the rotating shaft 4, and can be fixedly connected to the rotating shaft 4 by means of a keyway and a key. The connecting rod 6 is arranged in a V shape, one end of the connecting rod 6 is connected to the ferrule 51, and the other end is rotatably connected to the filter cartridge 7; a notch 16 is opened on the box body 1 above the partition 14, and the filter cartridge 7 can rotate through the notch 16 to reach the overflow port 15 position. With this design, only one rotating shaft 4 needs to be driven to rotate, so that the two gears 5 can be rotated synchronously, and then the connecting rod 6 can be driven to swing, so that the two filter cartridges 7 can be moved closer to each other and fit on the overflow port 15, or moved away from each other and reach the top of the box body 1. This design makes it easy to replace the filter cartridge 7, or clean the filter cartridge 7 in a timely and convenient manner, and reduces the clogging of the filter cartridge 7.
