Recycling device capable of circularly crushing rigid foamed plastic

Abstract

The invention discloses a recycling device capable of circularly crushing rigid foamed plastic, and relates to the technical field of plastic recycling equipment. The recycling device comprises a feeding box, a crushing box, a guide frame, a crushing cavity and a circular conveying cavity. According to the recycling device, rapid guiding feeding of the rigid foamed plastic to be crushed can be achieved through the gravity of the rigid foamed plastic, meanwhile, the fed rigid foamed plastic is flexibly supported and can be guided in a separated mode, and the feeding effect is good; a spiral conveying frame conveys the crushed rigid foamed plastic upwards, circular crushing machining can be achieved, and the crushing effect is enhanced; and when the crushing cavity conducts crushing treatment on the rigid foamed plastic to be crushed, an opening of a flexible hemispherical shell in a first guiding cavity faces upwards to conduct multiple limiting treatment on dust of splashing chippings, an opening of a flexible hemispherical shell in a second guiding cavity faces downwards to conduct multiple limiting treatment on dust of splashing chippings, anti-splashing and dustproof treatment in the feeding and crushing process can be effectively enhanced, and the safety of the working environment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of plastic recycling equipment, in particular to a recycling device for cyclically pulverizing rigid foam plastics. Background technique [0002] Rigid foam plastic refers to the foam plastic that has no flexibility, high compression hardness, deformation when the stress reaches a certain value, and cannot return to its original shape after the stress is relieved. The elastic modulus of rigid foam plastic is greater than 700MPa. Rigid foam plastics can be used as heat insulation materials, interlayer materials, packaging materials, sound insulation and shockproof materials, building materials, etc. With the rapid development of the rigid foam plastic industry, a large amount of rigid foam plastic waste needs to be recycled. When recycling the rigid foam plastic waste, it needs to be pulverized first. [0003] The existing recovery device for recyclable crushing of rigid foam plastics has poor feeding effect...
