Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic pipes, in particular to a shredding and recycling device for plastic pipes. Background Art
[0002] Plastic pipes are chemical building materials made from high-tech composites. They are the fourth largest emerging building material after steel, wood, and cement. They come in many varieties, including UPVC drainage pipes, UPVC water pipes, aluminum-plastic composite pipes, polyethylene (PE) water pipes, and polypropylene (PPR) hot water pipes. In addition, there are also chlorinated polyvinyl chloride (CPVC) pipes, cross-linked polyethylene (PE-X) pipes, polybutylene (PB) pipes, and acrylonitrile-butadiene-styrene (ABS) pipes.
[0003] When plastic pipes are discarded after their use cycle, they usually need to be shredded for effective recycling. However, during the shredding process, some raw material debris or pipe fragments will inevitably remain in the internal space of the processing chamber. The current processing chamber design is often only equipped with a feed port and a discharge port. While this design improves production continuity, it brings inconvenience to subsequent cleaning work. If the residue inside the processing chamber is not removed in time, it may accumulate and adhere to the surface or internal structure of the equipment. Over time, these residues may cause wear, blockage or other forms of damage to the equipment, thereby affecting the efficiency of subsequent processing operations and product quality.
[0004] Therefore, a plastic pipe shredding and recycling device is proposed. Utility Model Content
