Production line and method for recycling and granulating agricultural film

Abstract

The invention relates to an agricultural film recycling and granulation production line and method, comprising a cutting device, a first feeding device, a crushing device, a second feeding device, a cleaning device, a third feeding device, a drying device, granulator and unloading device, the cutting device is used to cut the bundled plastic film into long plastic strips; the first feeding device is used to transport the plastic strips obtained by the cutting device to the crushing device In; the crushing device is used to further crush the plastic strips into plastic sheets; the second feeding device is used to transport the plastic sheets obtained in the crushing device to the cleaning device; the cleaning device is used to realize the plastic sheet Cleaning; the third feeding device is used to transport the cleaned plastic sheets to the drying device; the drying device is used to dry the cleaned plastic sheets and transport them to the granulator. The invention can improve the efficiency of reusing the agricultural film and avoid soil pollution by the agricultural film by waste gas.

Description

technical field [0001] The invention belongs to the technical field of plastic film recycling, and in particular relates to an agricultural film recycling and granulation production line and method. Background technique [0002] Agricultural plastic film includes ground covering film and covering film for greenhouse roof. When agricultural film covers the ground or greenhouse, it can ensure that the space between the agricultural film and the soil has a set temperature and maintain the temperature and humidity of the soil. [0003] Plastic film is a non-degradable material, and waste plastic film in farmland will pollute the soil and hinder farming. Therefore, the recycling and reproduction of plastic film after use has become the treatment trend of the existing waste agricultural film. [0004] The inventor understands that the production line of existing agricultural film recycling has the following disadvantages: [0005] 1) There is no automatic cutting equipment for a...

AI Technical Summary

Problems solved by technology

[0005] 1) There is no automatic cutting equipment for agricultural film, it is necessary to manually cut the bundled agricultural film into long strips, and then send it to the crushing equipment, which is inconvenient to operate

[0006] 2) In the existing equipment for completely crushing agricultural film into plastic sheets, the crushing equipment does not have the effect of preliminary filtration. burden;

[0007] 3) The feeding device does not have the function of adjusting its own feeding height, so that when the feeding device is used in conjunction with cleaning equipment, crushing equipment or other equipment, the height cannot be adjusted conveniently to adapt to equipment with different feed inlet heights;

[0008] 4) There is no special feeding device in the existing production line, and it is impossible to cool and dehumidify the plastic granules produced by the granulator
