[0032] The sewage is passed into the filter frame 3 in the coarse filter area 11 of the housing 1 through the water inlet and outlet assembly 9. The filter frame 3 can coarsely filter the sewage and remove larger solid impurities such as leaves, sand, and fibers. The filter frame 3 is movably connected to the surface of the partition 2 to facilitate the dumping of impurities. The coarsely filtered sewage enters the filter cartridge 4 through the pipe assembly 5 for fine filtration, and then flows into the area outside the filter cartridge 4 in the housing 1 through the pipe assembly 5, and is finally discharged through the water inlet and outlet assembly 9. The end cover 41 covering the filter cartridge 4 can be easily opened, which is conducive to the rapid replacement of the filter medium and the continuous maintenance of a good filtering effect.

[0033] The joints between the box body 1 and the partition 2, the filter barrel, the end cover 41 and other components are coated with waterproof sealing coatings, such as silicon sealant, polyurethane sealant, polymer sealant, etc. to ensure sealing.

[0034] The end of the end cap 41 and the end of the filter cartridge 4 are respectively provided with external threads and internal threads, which match each other, and the filter cartridge 4 can be sealed by tightening the end cap 41. In addition to tightening, the end cap 41 can also be hinged to the end of the filter cartridge 4 and fastened by a fastening member, which is an existing conventional technology and will not be described in detail here.

[0035] In this embodiment, the filter screen frame 3 is provided with a flip frame 6, which is mounted on the surface of the partition plate 2. The filter screen frame 3 can be flipped by the flip frame 6 to dump out the impurities trapped in the filter screen frame 3, which is convenient for cleaning.

[0036] In this embodiment, both ends of the partition 2 extend out of the box body 1, and the flip frame 6 includes a rotating rod 61 and a pair of telescopic rods 62 which are respectively arranged on both sides of the box body 1 and whose fixed ends are screwed to the partition 2.

The extension of the telescopic rod 62 can make the filter screen frame 3 move vertically upward out of the inner cavity of the box body 1. At this time, the rotating rod 61 can be rotated to flip the filter screen frame 3 to dump the impurities trapped in the filter screen frame 3. If necessary, the bolts connecting the side wall surface of the filter screen frame 3 and the rotating rod 61 can be removed to replace the filter screen frame 3.

[0037] In this embodiment, a pair of telescopic rods 62 are each equipped with a telescopic motor 63, and the pair of telescopic motors 63 are both screwed to the surface of the partition 2, and the fixed ends of the pair of telescopic rods 62 are both connected to the output shaft of the telescopic motor 63; the rotating rod 61 is equipped with a rotating motor 64, and the end of the rotating rod 61 is connected to the output shaft of the rotating motor 64.

[0039] In this embodiment, there are three filter bags 71 filled in the filter cartridge 4, and the filter bags 71 from top to bottom are filled with polypropylene filter material 72, activated carbon filter material 72 and ceramic filter material 72 in sequence. The polypropylene filter material 72 is mainly used to further filter larger impurities such as solid particles, soil, sand, etc.; the activated carbon filter material 72 is mainly used to absorb and remove odor, residual chlorine, organic matter and some heavy metal ions in sewage; the ceramic filter material 72 is mainly used to filter tiny particles, bacteria, microorganisms, etc.

[0040] In this embodiment, the pipeline assembly 5 includes a liquid guide tube 51 and a liquid outlet tube 52; one end of the liquid guide tube 51 is connected to the top of the filter cartridge, and the other end of the liquid guide tube 51 passes through the through hole opened in the partition 2 and is connected to the coarse filter area 11; one end of the liquid outlet tube 52 is connected to the bottom of the filter cartridge, and the other end of the liquid outlet tube 52 is connected to the fine filter area 12. The liquid preliminarily filtered by the filter frame 3 is guided into the filter cartridge 4 through the liquid guide tube 51; the liquid filtered by the multi-layer filter element 7 in the filter cartridge 4 is discharged into the area below the partition 2 in the inner cavity of the box body 1 through the liquid outlet tube 52.

[0041] In this embodiment, a check valve 521 is arranged at one end of the liquid outlet pipe 52 away from the filter cartridge 4. The check valve 521 can be automatically opened or closed according to the flow direction of the medium. The check valve 521 prevents the filtered liquid from flowing back to the filter cartridge 4, thereby improving the processing efficiency.

[0042] In this embodiment, a UV lamp 8 is installed on one side of the partition 2 facing the filter cartridge 4. The UV lamp 8 can sterilize and deodorize the finely filtered water entering the area below the partition 2 of the box body 1.

The water inlet assembly 91 is arranged at the top of the box body 1, and the drain pipe 92 is connected to the bottom of the box body 1. Sewage is introduced from the top of the box body 1, and is sequentially coarsely filtered, finely filtered, and then discharged. The device has a compact structure and occupies a small area.

[0044] In this embodiment, the water inlet assembly 91 includes a water inlet pipe 911, a mounting rod 912 and a sleeve 913. The bottom of the mounting rod 912 is welded to the surface of the partition 2. The sleeve 913 is tilted and arranged at one end of the mounting rod 912 away from the partition 2. The side wall surface of the sleeve 913 is welded to the outer wall surface of the mounting rod 912. The water outlet end of the water inlet pipe 911 is penetrated through the sleeve 913, and the water outlet of the water inlet pipe 911 faces the inner cavity of the filter screen frame 3. The sleeve 913 and the water inlet pipe 911 in the sleeve 913 have a suitable tilt angle, so that the sewage can smoothly enter the filter screen frame 3 without affecting the lifting and turning of the filter screen frame 3.

[0045] In this embodiment, the limiting baffle 914 disposed on the port of the sleeve 913 facing the filter frame 3 can limit the water inlet pipe 911 to prevent the water inlet pipe 911 from extending too long.

[0046] In this embodiment, locking universal wheels 10 are provided at the bottom of the box 1 to facilitate movement to the working area.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
