Description

Technical Field

[0001] The present invention relates to the technical field of plastic recycling, and in particular to an environmentally friendly plastic recycling device. Background Art

[0002] With the widespread use of plastic products, the recycling and treatment of waste plastics has become a major issue in the field of environmental protection. Existing plastic recycling equipment typically processes plastic waste through steps such as crushing, cleaning, and melting, but this often results in a mixture of waste liquid and solid waste. Traditional equipment typically uses direct discharge or simple filtration to treat waste liquid, which not only easily leads to waste of resources but may also affect the subsequent treatment of solid waste due to residual waste liquid. In addition, when some equipment is stirring or treating solid waste, the waste is unevenly distributed, resulting in insufficient melting or chemical reaction, reducing the overall recycling efficiency.

[0003] Patent document CN119658877A in the prior art provides an environmentally friendly plastic recycling device; the device divides the processing component into a processing tank shell and a liquid collecting bottom cover, which correspond to the first crushing blade and the second crushing blade respectively, and can further crush small fragments that sink to the bottom, thereby ensuring the degree and effect of the device on the crushing of plastic bottles. In addition, the second crushing blade and the first crushing blade are both arranged upwardly and tilted from the inside to the outside, so that the crushed fragments can be continuously lifted up, which facilitates multiple crushing of the fragments instead of sinking them to the bottom once; However, the device still has the following problems: the device uses a specific shape of crushing blade to lift the plastic fragments while crushing them. (1) The blade uses a fixed tilt angle to lift the fragments, and only relies on the mechanical structure to promote the circulation of the fragments. This may cause some fragments to sink to the bottom quickly due to gravity, and it cannot ensure that all fragments are fully crushed. (2) If the fragments vary greatly in size or hardness (such as a mixture of soft films and hard bottle caps), the tilted blade may not be able to effectively lift light or soft fragments, resulting in uneven crushing, which is obviously a major defect.
