Description

Technical Field

[0001] The utility model relates to the technical field of separation devices, in particular to an impurity separator for recycling waste films. Background Art

[0002] In the process of recycling waste films, it is necessary to separate the impurities in the crushed films.

[0003] In the prior art, an environmentally friendly waste plastic film recycling and processing equipment with publication number CN214645070U adopts the scheme of "a feed pipe is inserted at the upper end of the crushing barrel, a funnel is fixed at the upper end of the feed pipe, an impurity outlet is inserted at the center position of the bottom end of the crushing barrel, and an air inlet is inserted at the lower end position of one side of the crushing barrel, and a storage pipe is inserted at the middle position of the other side of the crushing barrel". This scheme uses a crushing suction device to suck the crushed materials into the storage pipe for collection, which can separate the crushed materials from the impurity particles on the outside thereof, prevent the impurity particles from mixing into the crushed materials and causing damage to the recycling and processing equipment, and drive the plastic film into the crushing barrel at a uniform speed through the feeding auxiliary device to improve the uniformity of cutting and crushing.

[0004] However, the above scheme still has some shortcomings. For example, when it is actually cleaning the impurities in the film after crushing, it can only separate the film and the impurities, but cannot separate the metal fragments from the non-metal fragments in the impurities, and needs to be separated separately later. That is, the technical solution proposed by the above patent technology has the defect that it cannot effectively separate the metal fragments in the impurities.

[0005] In view of this, the utility model proposes an impurity separator for recycling waste films. Utility Model Content
