The inner wall of the cylinder 102 is provided with a kick-out plate 1021 and a push-in plate 1022, the push-in plate 1022 is provided with a separation sheet 1023 and a separation column 1024, the push-in plate 1022 is spirally arranged on the inner wall of the cylinder 102, the kick-out plate 1021 is arranged at the interval between the push-in plates 1022, two ends of the kick-out plate 1021 are connected with the push-in plate 1022, the separation column 1024 is arranged along the radial direction of the cylinder 102, one end of the separation column 1024 far away from the inner wall of the cylinder 102 is in a pointed cone shape, and the separation column 1024 is favorable for tearing and separating the bulk garbage.
When the cylinder 102 rotates, the pushing plate 1022 can push garbage to move from the feeding hole of the cylinder 102 to the discharging hole of the cylinder 102, the kick-out plate 1021 can stir the garbage in a lump upwards in the process of rotating the cylinder 102 and lift up the garbage, in the process of lifting up and dropping down the garbage, the separation column 1024 collides with the garbage to tear the garbage to form a large garbage into smaller garbage, and after the smaller garbage is lifted up again, the separation plate 1023 contacts and collides with the separation plate 1023, and the separation plate 1023 further divides the garbage and disperses the garbage. During the tearing of the clusters in contact with the separating sheet 1023 and the separating column 1024, the sediment stuck in the clusters will be separated from the plastic and sifted out of the mesh of the cylinder 102.
In this embodiment, the length of the separation column 1024 decreases from the inlet of the cylinder 102 to the outlet of the cylinder 102, i.e., the shorter the length of the separation column 1024 closer to the outlet of the cylinder 102. Because the waste is more dispersed nearer the discharge port of the cylinder 102, the volume of waste is smaller, and large clusters of waste have been progressively torn into smaller pieces during the process of approaching the discharge port of the cylinder 102, there is no need to provide an excessively long separator 1024 at the discharge port of the cylinder 102. If the overlong separation column 1024 is arranged at the discharge hole of the cylinder 102, the garbage can easily influence the garbage to pass through the discharge hole of the cylinder 102, so that the garbage is accumulated at the discharge hole of the cylinder 102, and the garbage needs to be manually dredged, which is not beneficial to subsequent processing.
In this embodiment, a conveyor belt is further disposed below the cylinder 102, impurities such as silt screened out from the mesh holes of the cylinder 102 fall onto the conveyor belt, and the conveyor belt conveys the impurities to an impurity recovery place for recovery, and of course, the conveyor belt may not be disposed below the cylinder 102, but a recovery tank or a recovery pool may be directly disposed below the cylinder 102. The screened impurities fall into the recycling bin or the recycling pool completely, and after the recycling bin or the recycling pool is fully loaded, workers recycle the impurities in the recycling bin or the recycling pool.
