Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

As shown in Fig. 1 and Fig. 2, the compacting silo in the described plastic film cleaning and recycling production line includes: a frame 1, and a storage hopper 2 and a feed hopper 3 installed on the frame 1, in the storage hopper 2 is provided with a ring-shaped vertical partition, and the ring-shaped vertical partition divides the interior of the storage hopper into relatively independent inner chambers and outer ring chambers. A discharge port is provided at the bottom of the inner chamber of the storage hopper 2. The mouth is connected with the feed port of the reversible conveyor 4, and a vertical screw conveyor for transporting the material in the storage hopper 2 from the discharge port to the reversible conveyor 4 is arranged in the inner chamber of the storage hopper 2 5.
