A clamping column 204 is also fixedly installed at the center of the inner end of 201, and the clamping column 204 matches the clamping groove 203. A backwashing suction cup 205 is also movably installed at the inner end of the filter cloth 202 in the fixed seat 102, and a backwashing pipe 206 is also fixedly installed on the upper end of the backwashing suction cup 205. The filter component 200 also includes a backwashing pump 207 fixedly connected to the upper end of the backwashing pipe 206, and the backwashing pump 207 is fixedly installed on the upper end of the filter body 100. The filter component 200 also includes an internal thread 208 set at the inner end of the fixed seat 102, and a positioning plate 209 threadedly connected and installed at the inner end of the internal thread 208, and the inner end of the positioning plate 209 is hexagonal.

[0025] Specifically, the rotary disc filter is a non-standard equipment, which is mainly used in the fields of water treatment and sewage treatment. The movable disc 201 movably installed in the fixed seat 102 at the outer end of the filter cartridge 101 in the filter body 100 can filter the effluent in the filter cartridge 101 again through the filter cloth 202 at its upper end, thereby improving its filtering effect on sewage. At the same time, the movable disc 201 can also rotate with the rotation of the filter cartridge 101 during backwashing, so that the impurities existing after filtering at its inner end can be removed through the backwash suction cup 205 at its inner end, thereby making it easier to clean the filter cloth 202 on the movable disc 201. The clamping groove 203 of the clamping column 204 opened at the upper end of the filter cartridge 101 is mainly used for the clamping connection between the filter cartridge 101 and the movable disc 201, so that the movable disc 201 can be driven to rotate during the rotation of the filter cartridge 101. The positioning disc 209 installed in the fixed seat 102 mainly realizes the clamping position of the clamping column 204 by positioning the position of the filter cartridge 101.

[0026] Embodiment 2:

[0027] Based on the first embodiment, Figure 3As shown, the stabilizing component 300 includes a connecting rod 301 fixedly installed at the center of the outer end of the movable disk 201, and a stabilizing frame 302 movably mounted on the outer end of the connecting rod 301. The stabilizing component 300 also includes mounting openings 303 opened at the upper and lower ends of the fixing seat 102, and mounting holes 304 and threaded holes 305 respectively opened on both sides of the stabilizing frame 302 and at the inner end of the mounting opening 303. Screws 306 are also movably installed in the mounting holes 304 and the threaded holes 305, and the stabilizing frame 302 is installed in the mounting opening 303.

[0028] Specifically, the stabilizing frame 302 mounted on the connecting rod 301 at the outer end of the movable disk 201 can also ensure the stability of the movable disk 201 as a whole when rotating with the filter cartridge 101, and the stabilizing frame 302 movably installed in the mounting openings 303 at the upper and lower ends of the fixed seat 102 and easy to disassemble can also make the movable disk 201 as a whole convenient and quick to disassemble and replace.

[0029] The working principle and use process of this utility model:

[0030] When the drive motor 103 at the upper end of the filter body 100 drives the filter cartridge 101 to rotate, the filter cartridge 101 will also drive the movable disk 201 in the fixed seat 102 to rotate stably as a whole under the restraint of the stabilizing frame 302 through the clamping column 204 at the inner end. When the movable disk 201 rotates, the backwash pump 207 at the upper end of the filter body 100 can also be started, so that the impurities existing in the filtration at the inner end of the filter cloth 202 can be sucked out through the backwash suction cup 205 at the inner end of the movable disk 201, so that the movable disk 201 can be easily cleaned during use.

[0031] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
