[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Please see Figure 1-4 As shown, a water filtration device includes a tank 4, with an inlet pipe 1 and an outlet pipe 5 connected to both ends of the tank 4. The tank 4 is divided into multiple chambers along its axial direction by several filter modules 7. An inspection port 8 is provided on the tank 4, and a sealing cover 3 is detachably connected to the inspection port 8. Each filter module 7 includes a cylindrical body 11, with a screen 12 fixedly connected to both ends of the cylindrical body 11. The filter module 7 is filled with filter media 13, and the cylindrical body 11 is sealed to the tank 4 via a sealing ring 10. Preferably, the filter media 13 is antibacterial filter beads. Specifically, the length of the inspection port 8 is greater than the diameter of the filter module 7, and the width of the inspection port 8 is greater than the thickness of the filter module 7, to facilitate the assembly and disassembly of the filter module 7.

[0029] When in use, the water to be treated is introduced into the tank 4 through the inlet pipe 1, filtered sequentially by multiple filter modules 7, and then discharged through the outlet pipe 5. When the filter module 7 needs maintenance, the sealing cover 3 is removed to open the inspection port 8, and the filter module 7 is taken out through the inspection port 8 for maintenance.

[0030] To facilitate backwashing of the filter media 13, the tank body 4 has an inlet pipe 1 connected to a backwash pipe 2 at one end. During backwashing, the inlet pipe 1 is closed and the outlet pipe 5 and backwash pipe 2 are opened, allowing the flushing water to enter through the outlet pipe 5 and exit through the backwash pipe 2.

[0031] The diameter of the plate screen 12 is larger than the diameter of the cylinder 11, and the sealing ring 10 is fitted onto the outside of the cylinder 11 and limited by the plate screen 12. By setting the plate screen 12, whose diameter is slightly larger than that of the cylinder 11, the sealing ring 10 is limited by the plate screen 12 to prevent it from falling off. Specifically, the cylinder 11 and the plate screen 12 are fixed by spot welding, and the joint between the two is sealed with sealant.

[0032] The tank 4 can have various shapes, including but not limited to rectangular, circular, elliptical, and conical shapes. The shape of the filter module 7 is adapted to the shape of the tank 4.

[0033] To prevent the filter modules 7 from shifting inside the tank 4, arc-shaped baffles 9 are fixedly connected to the inner wall of the tank 4 to limit the movement of the filter modules 7. The arc-shaped baffles 9 are located at both ends of the tank 4. A limiting frame 14 is provided between two adjacent filter modules 7. During installation, the filter modules 7 are placed in the tank 4 through the inspection port 8, and then pushed to the arc-shaped baffles 9 inside the tank 4 to limit their movement. Then, the limiting frame 14 is inserted to control the distance between the two filter modules 7. The above operation is repeated until all filter modules 7 are installed inside the tank 4.

[0034] Specifically, the filtration accuracy of the multiple filter modules 7 increases sequentially along the filtration direction.

[0035] In some embodiments, one end of the sealing cover 3 is hinged to the tank body 4, and the other end of the sealing cover 3 is fixedly connected to the tank body 4 by bolts. A sealing strip is fixedly connected to the inner side of the sealing cover 3 at a position corresponding to the inspection port 8. Specifically, the sealing cover 3 is hinged to the tank body 4 by a hinge, which makes it easier to open and close. After the sealing cover 3 is closed, it seals the inspection port 8 through the sealing strip, and at the same time, the filter module 7 is sealed to the inner wall of the sealing cover 3 through the sealing ring 10.

[0036] To facilitate the determination of the contamination status of the filter media 13, a water quality sensor 6 is installed on the side of the filter module 7 near the outlet pipe 5, and a display screen connected to the water quality sensor 6 is installed on the outside of the tank body 4. By setting multiple water quality sensors 6, the filtered water from each stage of the multi-stage filtration module 7 is detected, and the detected water contamination value is displayed on the screen to intuitively view the degree of contamination of the filter media 13, so as to backwash it in a timely manner or maintain or replace the corresponding filter module 7. When maintaining or replacing the filter module 7, the water quality sensor 6 should be removed first to avoid affecting the disassembly and assembly of the filter module 7. Specifically, the water quality sensor 6 is threadedly connected to the tank body 4.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
