Description

Production line for treating, sorting and recycling residual films

Technical Field

The invention relates to the technical field of cotton field residual film treatment, in particular to a residual film treatment, separation and recycling production line.

Background

The residual film of the cotton field obstructs the movement of the soil moisture of the cotton field on the plough layer and the surface layer of the soil, so that the moisture moving speed is reduced, the moisture permeation quantity is reduced, and the water conductivity is poor. The residual membrane aggregation reduces the porosity of the soil, destroys the normal circulation and exchange of the air of the cotton field soil to a certain extent, and reduces the permeability. The permeability is reduced, so that the normal activity of soil microorganisms is influenced, and the soil fertility level is reduced. Leading to difficulty in nutrient transport. The emergence rate in the field and the normal growth of the cotton are influenced, the seeds cannot normally emerge when being sowed on the residual film, the root system of the cotton is not favorably stretched, and the normal growth of the cotton is inhibited. The residual film isolation effect influences the normal nutrient absorption of cotton, influences the fertilizer utilization rate and further influences the quality and yield of cotton.

Carry out through plastic film residue collector now and carry out recycle to the plastic film residue, but can not effectively handle the plastic film residue of retrieving and select separately the use, the plastic film residue the inside that receives from plastic film residue collector for the farmland is adulterated cotton stalk, cotton, gravel and sand, soil, can not effectively handle the reuse, consequently needs a plastic film residue to handle to select separately the reuse production line and solves this problem.

s2, screening through a vibrating screen, conveying the residual film shredded by the shredder into the vibrating screen through a conveying belt, and screening out soil impurities in the residual film mixture and small broken rods generated by the operation of the shredder by the vibrating screen;

s3, introducing the plastic film residue mixture into an air separation bin, wherein a quantitative feed opening is formed in the bin, so that quantitative feeding and uniform feeding are guaranteed;

s4, performing air separation, discharging cotton stalks and cotton in the residual film mixture in an air separator, and extracting the film in a straw film separation device;

s5, conveying the mixture to a rotary screen, enabling a winnowing machine to enable the film extracted from the residual film mixture to enter the rotary screen from a discharge port for operation, screening cotton stalk sawdust with a small film surface in the rotary screen through rotating and dropping, and directly cleaning, regenerating and granulating the film screened out through the rotary screen.

(III) advantageous effects

The invention provides a residual film processing, sorting and recycling production line. The method has the following beneficial effects:

in contrast to the prior art, the invention uses a film shredder to break and crush cotton stalks, films and cotton, then the sand and the soil are conveyed to a vibrating screen through a conveyor belt, the sand and the soil are screened out through the vibrating screen, the screened film, the cotton stalk and the cotton are conveyed into a storage bin through the conveyor belt, get into straw film separator by the even unloading of feed bin and draw out the film, draw out cotton stalk and cotton mixture, the film of drawing out is by the discharge gate direct discharge drum sieve, and the film in the drum sieve separates away the very little pole bits of rare garrulous through rotatory the drooping, and the film that is gone out by the drum sieve discharge gate again directly can wash regeneration plastic granules to effectively improve the effect of handling the recycling to cotton field plastic film residue.
