Description

Technical Field

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

[0002] Marine plastic waste refers to plastic waste that enters the ocean. This waste mainly comes from plastic debris on land and eventually flows into the ocean through wind, rain, rivers and other channels. Marine plastic waste is a global problem that has had a serious impact on the marine ecological environment, marine life and human society.

[0003] Referring to patent publication number CN212888440U, a waste plastic recycling crushing device includes a machine body. The top of the machine body is connected to a feed inlet. A crushing device is fixedly installed on the left side of the inner wall of the machine body. A screening device is fixedly installed below the crushing device. A receiving box is placed at the bottom of the inner cavity of the machine body, and an inclined plate is fixedly installed inside the receiving box. This invention, through the arrangement of the machine body, feed inlet, crushing device, screening device, receiving box, inclined plate, and discharge pipe, can crush waste plastics. After processing, the plastics can be screened, and the screened fine plastics can be collected and recycled, effectively solving the problem of waste plastic waste and further improving economic efficiency. It also solves the problem that when crushing plastics, a large number of plastic particles are mixed in, preventing direct recycling and affecting the utilization rate of waste plastics.

[0004] While the above-mentioned method can crush marine plastics, it still has some shortcomings in its use. For example, due to the different qualities of the plastics, it is difficult to classify the plastics of different qualities after crushing, so that the staff need to screen the plastics a second time.

[0005] To address these issues, we propose a waste marine plastic crushing and screening device. Utility Model Content
