[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A disc filter assembly includes several sets of filter discs 9 for wastewater filtration and a base plate 1.

[0025] A pad 3 is installed at the top center of the base plate 1, and a sleeve 4 is fixedly installed at the top center of the pad 3. The surface of the sleeve 4 is provided with threads to increase the friction of the filter disc 9.

[0026] It also includes a mounting frame for arranging the filter discs 9. The top of the mounting frame has a mounting groove 8. The filter discs 9 for wastewater filtration are snapped into the inside of the mounting groove 8. A water outlet hole is opened on the inner bottom surface of the mounting groove 8. A slot 10 is opened in the center of the inner bottom surface of the mounting groove 8. A sleeve interface is opened in the center of the top of the filter discs 9. A seat 11 is provided above the sleeve interface. One end of the seat 11 passes through the sleeve interface and is snapped into the slot 10. A through hole is opened in the center of the inner bottom of the slot 10. A through opening is opened inside the seat 11. The through opening, sleeve interface and through opening are connected to each other.

[0027] The top surface of the base plate 1 is evenly distributed with six sets of positioning grooves 5, and the positioning grooves 5 are fitted with support blocks 12. The support blocks 12 are fixedly installed on the bottom of the mounting frame 7 and correspond to the positioning grooves 5. The bottom of the support blocks 12 is provided with anti-slip plates 13. By providing anti-slip plates 13, it is easy to make several sets of filter discs 9 have a certain anti-slip effect when stacked, and it also increases the stability of stacking several sets of filter discs 9.

[0028] This utility model uses components such as a base plate 1, a first connecting shaft 2, a pad 3, a sleeve 4, and a positioning groove 5 to work together, thereby facilitating the installation of several sets of mounting brackets 7 onto the base plate 1 and improving their placement stability. Furthermore, the pad 3 provides support and fixation for the mounting brackets 7 near the base plate 1; the positioning grooves 5 evenly distributed on the top of the base plate 1 facilitate positioning and securing of the mounting brackets 7 near the base plate 1; and the threads on the surface of the sleeve 4 improve the stability of the placement of several stacked filter discs 9.

[0029] Several sets of filter discs 9 are picked up by hand and then stacked one by one on the sleeve post 4 from bottom to bottom. The mounting bracket 7 near the base plate 1 is locked into the corresponding positioning groove 5 on the base plate 1 by the support block 12 on its bottom to fix it in place. Then, other filter discs 9 are picked up and put into the sleeve post 4 one by one through the sleeve interface provided inside, and stacked. During stacking, the anti-slip plate 13 provided at the bottom of the support block 12 makes it fit against the periphery of the mounting bracket 7 each time it is stacked, thereby improving the stability of the sleeve. At the same time, the stability of the filter discs 9 during stacking is increased by the thread provided on the outside of the sleeve post 4, and the displacement is prevented. The reverse operation can make it quick to disassemble.

[0030] The top surface of the base plate 1 has several sets of first water outlets 6, which are arranged around the positioning groove 5. By setting the first water outlets 6, it is convenient to discharge the filtered wastewater through them. A first connecting shaft 2 is installed at the bottom center of the base plate 1, which facilitates its rotational installation with the disc filter, so as to drive it to rotate and filter.

[0031] A top plate 15 is provided above the top of the sleeve column 4, and a threaded sleeve 14 is installed at the bottom center of the top plate 15. A threaded hole 16 is opened at the bottom center of the threaded sleeve 14. The internal threads of the threaded hole 16 are pressed and fitted to the card seat 11. A second connecting shaft 17 is fixedly installed at the top center of the top plate 15, and a second water outlet 18 is evenly distributed on the top surface of the top plate 15.

[0032] By setting the mating parts of the top plate 15, threaded sleeve 14 and threaded hole 16, it is easy to fix the sleeve column 4 with threads so as to press and fix the filter disc 9, thereby improving the stability of the filter disc 9 when it is placed in the filter disc assembly.

[0033] 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.
