[0024] Embodiment: A pre-drying device for raw materials for polyethylene film production, as Figures 1-3 shown, includes a drying tank 1. One side at the top of the drying tank 1 is communicated with a feed inlet 101. The bottom of the drying tank 1 is communicated with a water outlet 103. A filter screen 5 is fixedly connected at a position near the bottom of the inner cavity of the drying tank 1. A discharge outlet 102 is communicated on the side wall surface of the drying tank 1 and above the filter screen 5. A connection hole 104 is opened at the center of the top of the drying tank 1. A mounting frame 3 is fixedly connected to the drying tank 1 on the side away from the feed inlet 101 corresponding to the connection hole 104. A driving motor 301 is fixedly connected to the mounting frame 3 at a position corresponding to the connection hole 104. An electric push rod 302 is fixedly installed at the output shaft end of the driving motor 301. The extending end of the electric push rod 302 is adapted to the connection hole 104 and fixedly connected to a rotating rod 4. Two side wall surfaces of the rotating rod 4 are fixedly connected with C-shaped blades 401. The openings of the two C-shaped blades 401 are opposite. A plurality of through holes 402 are equidistantly opened on the two C-shaped blades 401. By designing the C-shaped blades 401 into a C shape, it is possible to better stir and push various polyethylene raw materials, promote the mixing process, and through the cooperation with the through holes 402, the eddy current during stirring can be increased, thereby more effectively mixing the polyethylene raw materials. A bearing plate 201 is fixedly installed on the side of the drying tank 1 away from the discharge outlet 102 and below the filter screen 5. A dryer 2 is installed on the bearing plate 201. The air outlet end of the dryer 2 is communicated with a connecting pipe 202. The connecting pipe 202 is located in the inner cavity of the drying tank 1. A plurality of air outlets 203 are communicated on the side wall surface of the connecting pipe 202 close to the filter screen 5.

[0025] Working Principle of the Present Invention:

[0026] In use, raw materials are put into the drying tank 1 through the feed inlet 101. By starting the driving motor 301, the electric push rod 302 and the dryer 2, the operation of the driving motor 301 can drive the electric push rod 302 to rotate, which can drive the rotating rod 4 to rotate. Then, the C-shaped blades 401 mix the raw materials. As the electric push rod 302 continuously moves up and down, the C-shaped blades on the rotating rod 4 continuously move up and down, fully mixing the raw materials at different positions in the inner cavity of the drying tank 1. The dryer 2 blows hot air from the air outlet 203, and at the same time, in cooperation with the C-shaped blades 401, the raw materials are dried more quickly.
