Embodiment 1

[0025] Such as figure 1 As shown, the waste plastic film recycling system of the present invention mainly includes a crushing and dry cleaning machine 1, a granulation system and a cooling device.

[0026] The crushing and dry-cleaning machine 1 includes a base 101, a driving mechanism 102, a feeding crushing mechanism, a double-layer drum, a screen, a casing 103, and a discharging mechanism. The driving mechanism 102 and the double-layer drum are arranged on the base 101, the screen is arranged on the bottom of the double-layer drum, the casing 103 is wrapped around the periphery of the double-layer drum, and the casing 103 is provided with a feeding crushing mechanism and an outlet. material organization. The discharge mechanism includes a dry-cleaning material outlet 113, an impurity outlet 115 and a suction hole 116, wherein the dry-cleaning material outlet 113 is located at one end of the casing 103, the impurity outlet 115 is positioned at the bottom of the casing 103, ...

Embodiment 2

[0034] Waste plastic film recovery processing method of the present invention comprises the following steps:

[0035] 1. Crushing and impurity removal: The recycled waste plastic film is broken into plastic film fragments through the crushing and dry cleaning machine 1, and the crushed plastic film fragments are rubbed and separated by the crushing and dry cleaning machine 1 to make the and / or adhering to the plastic film fragments Or the dust and impurities mixed in the plastic film fragments are separated from the plastic film fragments, and are discharged from the crushing dry cleaning machine 1 to realize the removal of impurities from the plastic film fragments.

[0036] 2. Granulation: the plastic film fragments after removal of impurities are sent to the feed port 203 at the top of the prilling tower 2 by wind in the feeding pipe 202, and fall freely in the prilling tower 2; The hot air port 209 blows hot blast, and the inlet temperature of the hot blast entering the pr...

Abstract

The invention provides a waste plastic film recovery processing system and method. The waste plastic film recovery processing system comprises a crushing dry washer, a pelleting system and a cooling device, wherein the crushing dry washer is used for crushing waste plastic film into plastic film chips and separating out dust and impurities carried by the plastic film chips in a dry washing mode; the pelleting system is used for plastifying the purified plastic film chips into plastic grains through hot wind; and the cooling device is used for cooling the plastified plastic grains into a normal temperature state to be discharged. The waste plastic film recovery processing method comprises the steps of crushing and purifying of the waste plastic film, pelleting and cooling, so that the plastic grains are obtained. According to the waste plastic film recovery processing system and method, renewable resources are effectively recycled, the automation degree is high, the processing steps are fewer, the energy consumption is low, and the efficiency is high; no waste water or smoke or odor is generated in the plastic film recovery processing process; and good environmental benefits and economic benefits are achieved, and the application prospects are broad.

Description

technical field [0001] The invention relates to recycling and processing of waste plastic films, in particular to a recycling and processing system and method for waste plastic films. Background technique [0002] With the development of modern science and technology, plastic products are ubiquitous in daily life, especially plastic cloth, plastic film and plastic bag products are more and more, and agricultural plastic film is gradually widely used, and a large amount of waste plastic film is produced every year . Since plastics are high molecular polymers with stable chemical properties, it is difficult to degrade in the natural environment, causing "white pollution". At present, waste plastic films are usually disposed of by landfill or incineration. Landfill disposal of waste plastic films occupies a large area of ​​land. After entering the soil, it will not degrade or rot for a long time, which seriously affects the permeability and water permeability of the soil, and ...
