Description

Green circulation recovery unit of nylon filament Technical Field The invention relates to the technical field of nylon filament recovery, in particular to a nylon filament green recycling device. Background The nylon 6 filament is a fiber made of polycaprolactam, has good wear resistance and softness, high strength and easy cleaning, and is often used for producing textiles such as clothing, socks, carpets, curtains and the like, and has larger demand in daily life, but for waste nylon 6 products, the nylon 6 products are not easy to naturally decompose due to the physical characteristics of wear resistance and high strength, so that the nylon 6 products can be recycled through a related physical or chemical method in view of environmental protection and resource saving. The chemical recovery is mainly that nylon 6 is crushed and screened into fragments conforming to a certain size, then the fragments are put into a dissolving device, acid or alkaline reagent is added to dissolve nylon 6 products, and then after the polymer chain of nylon 6 is decomposed into low molecular weight monomers or short chain polymers, residual reagent and impurities are removed by filtering, cleaning and other methods, and further relatively pure nylon 6 monomers or short chain polymers are polymerized to reform high molecular weight polymers and are used as production raw materials of fiber products again. However, due to the influence of the characteristics of the dissolved nylon 6 product, large fragments remain after crushing, and the sieve plates are mostly fixed when the existing sieving device is used for sieving, so that the large fragments can be blocked in front of or above the sieve plates and cannot be discharged in time, the sieving efficiency is affected, and the recycling efficiency is reduced. Disclosure of Invention The invention aims to provide a nylon filament green recycling device which has the effects of solving the technical problems, facilitating timely discharge of unqualified materials and being high in screening efficiency. The technical aim of the invention is achieved by the following technical scheme that the nylon filament green recycling device comprises a recycling barrel, wherein the top of the left end of the recycling barrel is provided with a feed hopper, the right end of the recycling barrel is provided with a feed opening, and a crushing assembly is arranged in the feed hopper and used for crushing nylon filaments; the screening assembly comprises a rotating shaft arranged in the recovery cylinder, the right end of the rotating shaft is fixedly connected with a screening plate, the inner wall of the right end of the recovery cylinder is provided with a circular chute, the screening plate is rotationally connected in the circular chute and is uniformly provided with screen holes, two sides of the interior of the recovery cylinder are provided with transverse chutes, the screening plate is symmetrically provided with sliding blocks, and the sliding blocks are in sliding connection with the transverse chutes; the winnowing component is used for blowing the nylon filaments entering from the feed hopper to the sieve plate; The temporary wind shielding assembly is used for temporarily blocking wind blowing to the screening plate during impurity discharging, an arc-shaped impurity discharging port is formed in the bottom of the recovery cylinder, and the arc-shaped impurity discharging port is located between the temporary wind shielding assembly and the screening plate; The driving assembly is used for intermittently driving the rotating shaft to move left and right and rotate back and forth, an installation cavity is formed in one side of the recovery cylinder, and the driving assembly is located in the installation cavity. Through adopting above-mentioned technical scheme, carry out screening during operation, broken subassembly falls into the recovery section of thick bamboo automatically after the nylon filament breakage in the feeder hopper, the selection by winnowing subassembly blows the piece to screening board department and sieves, pass the sieve mesh with the fragment of qualified size, fall into subsequent processing tank, it drives the screening board and rotates 180 to rotate the screening when the screening board is located circular spout to set up the drive assembly, it sieves to have the effect of avoiding the fragment of large block to hug closely the jam sieve mesh on the screening board, consequently, drive assembly removes the pivot and drives the screening board and remove left, the large block material on the screening board also removes left, the interim wind shielding subassembly blocks screening wind part, make the effect of large block material fall into arc miscellaneous mouthful discharge and carry out secondary breakage automatically, then remove the wind shielding subassembly, drive assembly drives the sieve right side, reverse 180 and realize the reset of screenin
