Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] like figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, the film sorting and recovery device includes a frame 1, in which a number of rotating shafts are movably supported sequentially along the conveying direction of the film, and several disc screens are evenly spaced on the shaft body of each rotating shaft. , all the rotating shafts rotate in the same direction at the same time under the drive of the drive mechanism, so that all the disc screens together form a sorting and conveying platform that can transport and screen the film backwards. The first rotating shaft 2, the second rotating shaft 21, the third rotating shaft 22, the fourth rotating shaft 23, the fifth rotating shaft 24, the sixth rotating shaft 25, the seventh rotating shaft 26, and the seventh rotating shaft 26 are movable and supported sequentially ...

Abstract

The invention discloses a film sorting and recovery device which comprises a rack. A plurality of rotary shafts are movably arranged in the rack in sequence in a supported mode in the film conveying direction. A plurality of disk sieves are arranged on a shaft body of each rotary shaft at intervals. All the rotary shafts rotate in the same direction under driving of a driving mechanism, so that all the disk sieves jointly form a sorting and conveying platform capable of conveying films backwards and sieving the films. In the film conveying direction, the distance between the disk sieves on each later rotary shaft is larger than the distance between the disk sieves on the previous adjacent rotary shaft. A material suction hood is arranged in the part, above the discharge end at the rear side of the sorting and conveying platform, of the rack. A suction port of the material suction hood is downwards aligned with the sorting and conveying platform. A discharge port of the material suction hood is connected with a negative-pressure draught fan through a suction pipeline. The film sorting and recovery device has the advantages that the sorting efficiency is high, the impurity content of the sorted and recovered films is low, and the sorting effect is good.

Description

technical field [0001] The invention relates to the field of film recovery and regeneration, in particular to a film sorting and recovery device for separating and recovering shredded films. Background technique [0002] Agricultural mulch film is a plastic film widely used in the agricultural field. It is mainly used to cover farmland to increase ground temperature, maintain soil moisture, promote seed germination and rapid growth of seedlings, and inhibit weed growth. Since the agricultural mulch film is made of polyethylene compound and its resin, it is non-perishable and difficult to decompose, so a large amount of waste agricultural mulch film remaining in the soil will destroy the ecological environment of the farmland; and because the agricultural mulch film is a modern economic development It is an important material that can realize "reduction, reuse, and recycling". Its production and processing are processes with no pollution, low consumption, and high efficiency....
