Marine multifunctional micro-plastic collecting device

Abstract

The invention discloses a marine multifunctional micro-plastic collecting device comprising a coarse particle filter tube, a fine particle collecting tube and a tail tube, wherein the coarse particlefilter tube, the fine particle collecting tube and the tail tube are sequentially connected from front to back; a flow guide cover is arranged at the front end of the coarse particle filter tube, andthe coarse particle filter tube is arranged at an opening part of the flow guide cover; a coarse particle filter screen is fixed in the rear part of the coarse particle filter tube; flow guide rings are arranged in the coarse particle filter screen; the flow guide rings are of an annular structure; a central concave hole of the flow guide cover is aligned to the middles of the flow guide rings; the flow guide rings are of a streamline structure; a channel between the central concave hole of the flow guide cover and the front ends of the flow guide rings forms a venturi tube shape with two thick ends and the fine middle; a circular channel between the flow guide rings and a channel between the flow guide rings and a shell of the coarse particle collecting tube also form a venturi tube shape; a fine particle filter screen is arranged between the fine particle collecting tube and the tail tube; and a venturi tube shape with two thick ends and a thin middle is formed between the tail partof the fine particle collecting tube and the tail tube. According to the marine multifunctional micro-plastic collecting device in the invention, the micro-plastic rubbish in the lake and the ocean can be collected.

Description

technical field [0001] The invention belongs to the field of pollutant collection devices, in particular to a marine multifunctional microplastic collection device. Background technique [0002] Microplastics refer to plastic particles with a diameter less than or equal to 5mm. They often only contain the basic chemical components of plastics without additives, and some of them are added to cosmetics, hand sanitizers, toothpaste, cleaning agents and other care products as scrub ingredients. The other part is fragments of larger plastic products that break apart, such as the fragmentation of large pieces of plastic and the tearing of clothing fibers. With economic development and people's increasing use of plastic products, more and more microplastic particles have entered water bodies, and the current microplastic pollution in oceans, lakes and other water bodies has gradually received attention. [0003] Chinese patent application number 201810797863.4 discloses a mobile ...
