Then, the first filter cleaning body and the second filter cleaning body are driven to rotate by the driving connecting shaft. The rotating first filter cleaning body and second filter cleaning body generate centrifugal force, causing the impurities collected at the edges of the conical filter discs in the first filter cleaning body and the second filter cleaning body to be thrown out and separated from the conical filter discs, enabling the intercepted impurities to be quickly cleaned, removed, and separated from the conical filter discs in the first filter cleaning body and the second filter cleaning body, making the device convenient to clean and highly efficient in use.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-3 , an embodiment provided by the present utility model: a filter disc for the production of combined polyether, comprising a driving connection shaft 1, a first filter cleaning body 2 and a second filter cleaning body 3. The first filter cleaning body 2 is arranged on the second filter cleaning body 3. The driving connection shaft 1 is fixedly connected between the middles of the first filter cleaning body 2 and the second filter cleaning body 3. And the first filter cleaning body 2 and the second filter cleaning body 3 have the same structure. The first filter cleaning body 2 and the second filter cleaning body 3 both include a conical filter disc 7, a partition vertical plate 8 and filter intercepting holes 10. The partition vertical plate 8 is fixedly connected to the upper parts of both ends of the conical filter disc 7. The filter intercepting holes 10 are uniformly and penetratingly opened thereon.

[0018] Limiting card slots 6 are symmetrically and penetratingly opened on the conical filter disc 7. A sliding partition board 9 is slidably clamped inside the limiting card slots 6, which plays a role of partitioning and collecting.
