Description

Crusher of sea waste

The present invention relates to a marine debris shredding device, and more particularly, to a marine debris shredding device capable of smooth landing of marine debris by crushing marine debris to reduce its volume.

In general, marine debris is deposited into the sea or floats on the surface of seawater depending on its composition. In particular, most of the marine debris is floating, moving here and there, and it takes a long time to decompose, thus continuously affecting the marine ecosystem.

Such marine garbage, that is, waste includes land-based marine waste generated on land, marine waste generated on the sea, and the like. Marine waste, which is land-based, is waste or garbage generated on land, the coast, or marine leisure facilities, and flows into the sea in large quantities through rivers, rivers, or urban sewage facilities during heavy rains or floods. Marine waste, which is a marine waste, is garbage dumped into the sea during the operation or fishing of cage farms or ships, and plastic ropes, fishing nets, and plastic floats account for a large amount.

Such marine waste, such as marine waste, is very diverse, such as plastic, vinyl, metal, wood, and rubber paper. Among these marine wastes, it is estimated that 57 million tons, or 30% of the annual production (190 million tons) of plastic, which has the greatest adverse impact on the marine ecosystem, flows into the ocean or is dumped.

Discharge of waste against hazardous substances to the sea is completely prohibited, and waste in ships is to be disposed of by disembarking after storage.

Considering this point, the volume is relatively reduced by crushing marine wastes generated from ships or wastes collected from the sea.

On the other hand, the Republic of Korea Patent Registration No. 595026 discloses a marine mobile recovery processing system, and the Republic of Korea Patent Registration No. 3763020 discloses a marine sludge crushing and collecting device.

The posted marine sludge crushing and collecting device includes a casing; a crushing screw, an upper screw, and an auxiliary screw selectively operated through hydraulic motors provided on the upper and left and right sides of the receiving space provided on one side of the casing; a hydraulic cylinder for moving the crushing screw forward and backward in the horizontal direction of the receiving space; and a pair of tongs axially rotating in an opening/closing form by the operation of a hydraulic cylinder provided at the bottom of the accommodation space.

The crushed water storage device as described above has a relatively complex structure, and it is difficult to use it by being mounted on a bulker ship or offshore structure.
