[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figure 1 As shown,

[0020] A self-cleaning filter screen of a dehydrator for cleaning thin film raw materials is characterized in that it includes a left end plate 1 and a right end plate 2, the left end plate 1 is rotatably connected to a left-rotating body 3, the right end plate 2 is rotatably connected to a right-rotating body 4, a filter screen body 5 is connected between the left-rotating body 3 and the right-rotating body 4, the left end plate 1 is provided with an independent self-rotating component, and the left end plate 1 and the right end plate 2 are both provided with four-wheel positioning components.

[0021] In this embodiment, the film raw material and water enter from the dehydrator feed port, pass through the left end plate 1 and the left rotating body 3, and enter the filter body 5. The dehydrator drives the left end plate 1 and the right end plate 2 to rotate, so that the filter body 5 rotates to separate the film raw material and water. Finally, the separated film raw material passes through the right end plate 2 and the right rotating body 4 and is sucked out. During separation, the independent self-rotating assembly drives the filter body 5, the left rotating body 3 and the right rotating body 4 to rotate on the left end plate 1 and the right end plate 2, which greatly reduces the adhesion of the film raw material on the filter screen, thereby reducing the clogging of the filter screen and achieving a self-cleaning effect; the left rotating body 3 and the right rotating body 4 adopt a four-wheel positioning type to ensure that the entire filter screen has good concentricity during rotation.

[0022] In this embodiment, the filter body 5 is a stepped filter, which gradually reduces the dehydration area of ​​the filter according to the dehydration amount.

[0023] In this embodiment, the independent self-rotating assembly includes a gear rotatably connected to the left end plate 1. A ring gear 6 is mounted on the left-hand rotating body 3, and the gear meshes with the ring gear 6. An external motor drives the gear, which in turn drives the ring gear 6, the left-hand rotating body 3, the filter body 5, and the right-hand rotating body 4. This adds an independent self-rotating system that can rotate independently, significantly reducing the adhesion of film material to the filter screen, thereby reducing filter clogging and achieving a self-cleaning effect.

[0024] In this embodiment, the four-wheel alignment assembly includes four alignment wheels 7, which are rotatably connected to the left end plate 1 or the right end plate 2. The four alignment wheels 7 are arranged in a circumferential array along the central axis of the filter body 5. The alignment wheels 7 abut against the left-hand rotating body 3 and the right-hand rotating body 4. The four-wheel alignment of the left-hand rotating body 3 and the right-hand rotating body 4 ensures that the entire filter body 5 has good concentricity during rotation.

[0025] In this embodiment, a U-shaped groove 8 is formed on both the left end plate 1 and the right end plate 2, and a sealing strip 9 is provided in the U-shaped groove 8. The sealing strip 9 is placed in the U-shaped groove 8 of the left end plate 1 and the right end plate 2 to ensure that the dehydrator cover is completely sealed when closed.

[0026] In this embodiment, the left-hand rotating body 3, the right-hand rotating body 4 and the filter body 5 are connected by bolts. The bolt connection makes assembly and disassembly convenient and quick.

[0027] In this embodiment, a washer 10 is provided at the bolt.

[0028] In this embodiment, the filter body 5 is made of stainless steel.
