Embodiment Construction

[0025] exist figure 1 Middle: The flow of equipment used in the cleaning process is film crusher 1→screw feeder Ⅰ2→friction cleaning machine 3→screw feeder Ⅱ4→rinsing tank 5→screw feeder Ⅲ6→squeeze dryer 7→air delivery system 8→storage Bin 9. Waste plastic film cleaning is a fully automatic 1500-2000kg / h PE film cleaning production line. The power supply is 380V, 50Hz, 3 phases; the installed power is about 220KW; the actual power consumption is about 130-160KWH; the water consumption is 10-15 tons of circulating water, and the water loss is 2-3 tons / day; the equipment covers an area of ​​about 300m 2 , can be arranged according to the workshop, 2-3 workers / shift. Screw feeder I2, screw feeder II4 and screw feeder III6 are the same. The above-mentioned equipments are purchased parts.

[0026] Cleaning has the following sequential steps:

[0027] ① The recovered waste plastic film is classified and sorted for pretreatment, and then manually coarsely crushed. The purpose o...

Abstract

The invention relates to a method for recycling, cleaning and granulating waste mulching films. The method comprises the steps of cleaning and granulating. In the cleaning step, the recycled waste mulching films are classified, sorted and pretreated, are conveyed into a thin film crusher for crushing, are conveyed into a frictional cleaner through a spiral conveyor I for cleaning, are conveyed to a rinsing tank through a spiral conveyor II for secondary cleaning, are conveyed to a squeezing machine through a spiral conveyor III, and are conveyed into a storage bin through a pneumatic conveying system I. In the granulating step, the waste mulching films are conveyed to a cutting compaction cylinder through a conveying belt for treatment, treated materials are automatically forced to be pushed into an SJ150 / 26 single-screw extruder, a melt is extruded through a hydraulic screen exchanger and is directly cut into uniform particles on a mold surface through a water ring granulator, the particles are conveyed into a centrifugal dehydrator for dehydration treatment, and the dehydrated particles are conveyed into the storage bin through a pneumatic conveying system II, and are bagged and stored at an outlet of the storage bin. According to an advanced method for recycling, cleaning and granulating the waste mulching films, the environment pollution is avoided, and resources are recycled.

Description

technical field [0001] The invention relates to recycling and reuse of waste plastic film, and more specifically relates to a processing method for recycling, regeneration, cleaning and granulation of waste plastic film. The discarded mulch film and shed film in the surrounding areas and various provinces and cities, as well as the corner waste generated in the production process, non-standard films, trimmings, and also recyclable plastic pipes, part of the lead materials or substandard products in the production process of profiles, can be injected into production The fully automatic granulation method of recycling the waste mulch film and shed film by applying the principle of plastic thermoplastic to the unfilled parts, other waste plastics, etc., can be used to produce plastic products again. Background technique [0002] In recent years, since my country's plastic film mulching technology has been popularized and used on a large scale, it can store water and moisture, i...
