The water inlet 211 is set on the first part 21, and the second part 22 is relatively complete, so that the second part 22 and the first part 21 are more convenient to assemble. The bottom of the slag collecting basket 3 is detachably restrained at the bottom of the return water area 11, and the top of the slag collecting basket 3 forms a downward restraining force on the second part 22 at the slag collecting port 31. At least a part of the second part 22 is slightly deformed under the action of the restraining force to form a tendency to sink from the edge to the slag collecting port 31.

[0026] Specifically, the edge of the mounting opening 221 of the second part 22 is sunken to form a mounting platform 222, and the outer peripheral wall of the slag collecting basket 3 is provided with a mounting ring 32 extending radially and resting on the mounting platform 222, and the slag collecting opening 31 is located above the mounting ring 32. Such a structure is adopted to realize the force constraint of the slag collecting basket 3 on the second part 22 of the filter plate 2. When the slag collecting basket 3 is constrained at the bottom of the return water area 21, the mounting platform 222 of the second part 22 and the outer part of the mounting opening 221 form a tendency to slightly deform downward under the pressure of the mounting ring 32.

[0027] The upper surface of the second portion 22 forms a guide surface 223 which gradually slopes downward from the edge to the slag collecting opening 31. The guide surface 223 is beneficial to improving the guide effect near the slag collecting opening 31, thereby improving the slag collecting effect.

[0028] In this embodiment, a drain port 12 corresponding to the bottom of the slag collecting basket 3 is opened at the bottom of the return water area 11, and the lower end of the slag collecting basket 3 is plugged and limitedly connected with the drain port 12.

The above structure facilitates the disassembly and assembly of the slag collecting basket 3.

[0030] In this embodiment, the edge of the first part 21 constitutes the edge of the filter plate 1, and the first part 21 is provided with an opening 212 near its local edge and in conformity with the shape of the second part 22, and the second part 22 is embedded in the opening 212. The contour of the filter plate 2 is formed by the edge of the plastic first part 21, and the opening 212 is provided near the local edge of the first part 21, and the metal second part 22 is embedded in the opening 212. When it is necessary to repair the functional parts under the filter plate 2, the second part 22 can be removed and operated through the opening 212; because the second part 22 is surrounded by the first part 21, the assembly gap between the two can be conveniently made small, thereby reducing the accumulation of residues to improve the cleanliness of the filter plate.

[0031] The bottom edge of the opening 212 is provided with an inwardly extending support edge 213, the second part 22 abuts against the support edge 213, and the support edge 213 is provided with a slag discharge port 214 that passes through from top to bottom. This structure can support the second part 22, facilitate the assembly of the first part 21 and the second part 22, and discharge the residue in time.
