Description

Crusher of sea waste

The present invention relates to an apparatus for crushing marine debris, and more particularly, to classify and sort marine debris into non-combustible marine debris and combustible marine debris, and to form the selected combustible marine debris into solid fuel. When crushing combustible marine debris with a crushing device, the crushing drum of the crushing unit of the crushing unit is formed with a single shaft, and the crushing tip is formed in a W-shaped pattern on the crushing drum driven only by one shaft, Maximizes process efficiency by automatically moving combustible marine debris to the center of the shredding drum and preventing it from being wound on the rotating shaft, maintaining the safety and reliability of the marine debris shredding device, and operating efficiency of the marine debris pretreatment system through one-stop service It relates to a marine debris shredding device that can increase and reduce management costs.

In general, marine debris is deposited into the sea or floats on the surface of seawater depending on its composition. That is, specifically, marine debris may be deposited into the sea or float on the surface of seawater depending on its composition.

In particular, most of the marine debris is floating, moving from place to place, and taking a long time to decompose, continuously affecting the marine ecosystem.

Such marine debris includes, for example, land-based marine debris generated on land, and marine debris generated at sea.

Domestic offshore marine debris generated by land-based, maritime-based, and fishing activity causes problems such as destruction of the coastal environment, damage to marine ecosystems, and maritime safety. Due to the expansion and urbanization of coastal industrial complexes in the coastal waters, and the increase in the emission of aspirations due to the improvement of living standards, marine floating garbage, sedimentary garbage on the seabed, and polluted sediments have reached a serious state beyond the purification capacity of the ocean itself. .

Specifically, land-based marine waste 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.

In addition, marine garbage, which is a marine aircraft, is garbage dumped into the sea during the operation or fishing of a cage farm or a ship, and plastic ropes, fishing nets, plastic floats, and the like account for a large amount.

Such marine debris is very diverse, such as plastic, vinyl, metal, wood, rubber paper, and the like. Among these marine debris, 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. However, the discharge of waste against hazardous substances to the sea is completely prohibited, and waste in ships is stored and disembarked to be disposed of.

In recent years, various studies on the actual condition of marine pollution sources and their effects on the marine ecosystem are being conducted.

Research and efforts on this are multifaceted efforts to develop and introduce practical equipment for investigation, prevention, collection, treatment and recycling of marine waste. On the other hand, due to the universal spread of the awareness of recycling of energy, many efforts are being made for recycling of marine debris.

Compared to land waste, marine waste has advantages in that it is simple in composition, contains a large amount of recyclable materials, has a high calorific value, and does not require prompt treatment due to its low possibility of decay or odor.

On the other hand, the moisture content between wastes fluctuates greatly, the risk of corrosion of treatment facilities due to salt is high, and there are many wastes that require cutting and crushing, and the location of generation is dispersed, making it difficult to collect or organize the collection system.

Considering these characteristics of marine debris, the development of a marine debris pretreatment system that removes salt and foreign substances contained in marine debris was preceded for stable treatment of marine debris.

A technical approach to the treatment of the collected marine debris should start with the stabilization of the marine debris added with seawater and lead to the recycling of the marine debris due to the characteristics of the marine debris.

Currently, scrubbers, sorters, and cutters are used to prevent corrosion of treatment facilities due to salt, to enable the treatment of coarse wastes (nets, ropes, etc.) Although a pre-treatment system consisting of , shredder, dehydrator, and dryer is used, in general, there is a distance from the place where marine debris accumulated on the coast is collected. The problem remains.

On the other hand, the occurrence of various environmental problems such as destruction of the living environment due to the transport of marine debris has made the residents object to the installation of environmental facilities, and the effect is even affecting the disposal of marine waste.

Accordingly, conventional marine waste is classified and sorted into combustible marine waste and non-combustible marine waste, and the classified and sorted non-combustible marine waste is separately treated in an environmentally friendly manner in accordance with legal measures through a process such as sorting and shredding for each type. Such non-combustible landfill waste is not treated in the recycling process, but instead sent to an eco-friendly treatment facility.

In other words, in order to make it possible to convert combustible marine waste centered on plastics, which is the main cause of marine environmental pollution, into fuel, the marine waste pretreatment facility separates marine waste into combustible marine waste and non-combustible marine waste, and converts the selected combustible marine waste into solid fuel. It is transported to the device and recycled as a resource through solid fuel conversion.

In general, the marine debris pretreatment system transports the stacked and collected combustible marine debris through a sorting device and a sorting device that classifies the collected marine debris (5) into incombustible marine debris and combustible marine debris to convert marine debris into solid fuel. and a marine debris crushing device for crushing combustible marine debris transported through the transport device, and a solid fuel conversion device is disposed adjacent to the marine debris pretreatment system. Accordingly, the marine debris pretreatment system is miniaturized by optimally arranging the marine debris crusher, sorting device, and transport device, and overall management by reducing the cost and time for the pretreatment of marine debris through process simplification through the operation of a one-stop system It is possible to reduce costs and maximize space utilization to reduce installation time and costs, to maximize the recycling efficiency of marine debris to protect the environment through resource recycling, and to improve solidified fuel productivity. In addition, the transport device is formed in the same shape as a crane, and transports the loaded combustible marine debris by sorting and sorting through the sorting device to the marine debris shredding device. In addition, although not shown in the drawings, the combustible marine debris crushed by the marine debris crusher is transported to the solid fuel conversion device through a drying device, etc., and is molded into solid fuel, and resources are recycled.

In general, marine debris is classified and sorted into combustible marine debris and non-combustible marine debris through a sorting device 2 as shown in FIG. 1 in the marine debris pretreatment system, and the sorted combustible marine debris 5 is It is crushed through the same marine debris shredding device 3, and non-combustible marine debris is separately collected and treated in an environmentally friendly manner.

In the conventional marine debris crusher, secondary pollution is generated by mixing dust and incombustibles in the sorting process through an air suction sorting device. There was a problem in that time and time was consumed, causing inconvenience to the operator, and increasing the maintenance cost.

In addition, the conventional marine debris shredding device is configured in the form of a two-axis roller 4 as shown in FIG. 3 , and the marine debris such as a net is pushed out on both sides and wound around the operating part of the roller 4 to stop or stop the crushing efficiency. Due to this decrease, there was a problem in that the efficiency of the pretreatment process for marine debris was reduced.

Moreover, the conventional marine debris shredding device is configured in a two-axis drum type, and as the marine debris is pushed out on both sides, damage or damage to the equipment increases, increasing maintenance time and cost, causing inconvenience to workers, and safety accidents. There were problems in that the solidified fuel production efficiency was reduced, and the reliability and safety of the equipment was reduced.

In addition, in the conventional marine debris shredding device, the crushing device and the sorting device are not unified, they are separated from each other, and the arrangement and structure of the sorting device, the transporting device, and the crushing device in the marine debris pretreatment system are not optimized. It is not possible to do this, which reduces manufacturing cost and manufacturing time, reduces space utilization, consumes a lot of money and time for installation, increases management cost, and reduces operational efficiency because one-stop service cannot be achieved. There was a problem.
