Description

Technical Field

[0001] This application relates to the field of plastic processing technology, and in particular to a waste marine plastic crushing device. Background Technology

[0002] Large amounts of plastic waste enter the ocean, causing serious damage to the marine ecosystem. Every year, millions of tons of plastic waste flow into the ocean. These plastics are difficult to degrade in seawater and break down into microplastic particles, which are ingested by marine life and then endanger human health through the food chain. Therefore, it is necessary to recycle, crush, and reuse plastic waste in the ocean.

[0003] Current crushing devices suffer from the problem that waste plastics, having floated in the ocean for extended periods, accumulate large amounts of seawater on their surfaces. This seawater may also be contaminated with salt, microorganisms, and other corrosive substances. When these waste plastics are fed into the crushing device, the residual seawater is splashed onto the inside and outside of the device by the impact of the high-speed rotating blades and mechanical parts. This can cause rust, wear, or even failure of critical components such as blades, bearings, and housings, thus shortening the device's lifespan. Therefore, we propose a waste marine plastic crushing device to address these issues. Utility Model Content
