Description

Volume reducing system for waste styrofoams of aquafarm's float}

The present invention relates to a device for reducing waste styrofoam such as rich used in aquaculture farms, specifically, rich waste styrofoam for aquaculture farms containing foreign substances such as seawater, oysters, clam shells are continuously crushed, washed, dehydrated, dried, The present invention relates to a waste styrofoam reduction apparatus that is cut by cutting. In particular, the present invention relates to a device in which foreign substances such as seawater, oysters, shells, etc. are separated, removed, and reduced by washing, dehydration, and drying before saping. In addition, the present invention relates to a waste styrofoam sensitization apparatus in which evaporated water or noxious gas generated in the process of reducing waste styrofoam is safely treated, and the quality of regenerated styrofoam is stabilized by a subsequent process.

In general, styrofoam is called expanded styrene (EPS), styrofoam (Styrofoam), and is a foamed product in which hydrocarbon gas such as pentane or butane is injected into the polystyrene resin and then inflated with steam, and 98% of the volume is air. The remaining 2% is synthetic resin material.

Due to the characteristics of these light styrofoam, it is widely used as a rich farm. However, waste styrofoam, which is left unused after use, is generated in large quantities in the South Sea coastal farm. The disposal of waste styrofoam is not effective because the volume of waste styrofoam is large and does not rot well. Incineration of waste styrofoam is not a good way because environmental pollutants such as dioxins are generated. Waste styrofoam used as a rich farm for fish farming is not allowed due to lack of proper treatment.

Conventionally, a method of dissolving waste styrofoam at high temperature or dissolving it with chemicals has also been tried, but there was a limitation in treating a large amount of waste styrofoam and there was an inefficient problem.

In addition, the waste styrofoam reducing apparatus disclosed in the Republic of Korea Patent Publication No. 96-3914 is conventionally installed on the inlet of the extruder 1, so as to face two grinding shafts fixed two grinding blades A grinder 2 mounted to rotate in opposite directions; The screw device is rotatably housed inside the cylinder, and the die-to-outlet with the stagnation chamber and the discharge port is connected and fixed to the end of the screw device. It consisted of (1) and there existed the effect of melt | dissolving and liquefying waste styrofoam by compression heat. However, waste styrofoam, such as rich for farming, contains foreign matters such as oysters, shells, etc., so that the waste styrofoam reducing device stops or breaks the machine even during extrusion. In addition, when the reduction apparatus such as the conventional design above compresses and reduces waste styrofoam having only a small amount of moisture on the outside, such as waste styrofoam used to package electronic parts, power consumption is increased due to evaporated water. Compression was reduced. However, in the case of the conventional apparatus such as the conventional invention, when compressed and reduced waste styrofoam such as the rich farming seawater infiltrated by seawater, direct and indirect heat is applied to the waste styrofoam to generate water vapor, thereby remaining in the waste styrofoam. The blowing agent such as pentane and butane is foamed again by physical state change or chemical reaction, and there is a problem that the noise is severe and the waste styrofoam is hardened in the screw of the reducer before the compressed and reduced pressure. In addition, the evaporated water generated in the process of melting saponification, harmful gas flows back to cause a bad smell to workers or there was a harmful problem. In addition, some of the foreign matter was included in the waste styrofoam, there was a problem that the quality of the recycled styrofoam.

In order to solve the above problems and the like, an object of the present invention is to provide a device for reducing waste styrofoam such as rich used in aquaculture farms.

It is also an object of the present invention to provide a waste styrofoam sensitization apparatus in which waste styrofoam is cut and cut after foreign matters such as seawater, oysters, shells and shells are continuously separated and removed from the rich waste styrofoam for farming.

It is also an object of the present invention to provide a waste styrofoam reduction apparatus in which a large amount of waste styrofoam can be efficiently and quickly reduced.

It is also an object of the present invention to provide a waste styrofoam reduction apparatus in which waste styrofoam is washed continuously and effectively to remove foreign substances such as oysters and shells and to reduce the salt concentration of waste styrofoam.

In addition, an object of the present invention relates to a waste styrofoam sensitization apparatus in which evaporated water or noxious gas generated in the process of waste styrofoam is treated safely and the quality of regenerated styrofoam is stabilized by a subsequent process.
