A plurality of anti-corrosion screws 17 are detachably connected to both of the two inner ring plates 16. The plurality of anti-corrosion screws 17 are respectively detachably connected to the corresponding inner ring plates 16 at equal intervals. A partition rod frame 18 is installed on both of the two inner ring plates 16. The filtering cylinder 13 is as Figure 2As shown in the figure, it has a large area and good filtering effect. During installation, after putting the right side of the filter cartridge 13 into the first channel 2, the clamping rod 15 on the right side surface of the filter cartridge 13 is initially fixed to the card slot 12 on the connecting pipe cover 8 installed on the upper part of the first channel 2. Then, the drainage pipe 7 is sleeved on the left side of the filter cartridge 13. At this time, the clamping rod 15 on the left side surface of the filter cartridge 13 is initially fixed to the card slot 12 on the connecting pipe cover 8 installed on the drainage pipe 7.
