A kind of production equipment and preparation process of waste plastic film particles

Abstract

The invention discloses production equipment for waste and old mulching film granules. The production equipment comprises a shredding machine, a conveying belt I, a roll separation machine, a conveying belt II, a crusher, a high-speed frictional cleaning device, a primary bleaching device, a conveying auger, a secondary bleaching device, an extruding and drying machine, a dispersing machine, a fan, a heating bag, a suctioning fan, a drying pipeline, and a storage bin, wherein one end of the shredding machine is connected with the conveying belt I; the other end of the conveying belt I is connected with the roller separation machine which is connected with the crusher by the conveying belt II; the primary bleaching device is arranged at the rear side of the high-speed frictional cleaning device and is connected with the secondary bleaching device which is connected with the extruding and drying machine; the lower side of the extruding and drying machine is connected on the dispersing machine; the secondary bleaching device and the dispersing machine are connected with the fan and the heating bag; and the suctioning fan and the drying pipeline are connected between the dispersing machine and the storage bin. A preparation process comprises the following steps: cleaning, frictional cleaning, bleaching, extruding and drying, dispersing, drying, aggregating the granules, plasticized filtering, cutting into the granules, dewatering and bagging.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to waste plastic film granule production equipment and a preparation process thereof. Background technique [0002] At present, there is no relatively mature technology in China that can process and produce waste plastic film particles in large quantities, which restricts the recycling and reuse of waste plastic film. Most of the waste plastic film is not recycled and reused, but landfill and incineration are the main treatment methods. This method not only wastes resources, but also causes environmental pollution and seriously damages the land quality. The process of the invention can effectively improve the output and quality of waste plastic film particles, and the whole production process does not produce pollutants, has a good environmental protection process level, and effectively realizes the transformation from waste plastic film to waste plastic f...
