Description

Organic waste drying device}

The present invention relates to an organic waste drying device for reducing and processing organic waste.

In general, in recent years, the waste problem has become a social problem worldwide, and secondary pollution occurs during the incineration and landfill treatment of the waste, which occurs during the sewage and wastewater treatment process, which can be the most problematic among the characteristics of waste. Interest in the treatment of organic waste such as impurities and sludge has increased.

The contaminants include various types of foreign substances such as food waste, hair, wet tissues, and plastics, and among these contaminants, organic waste such as food waste, hair, and wet tissues are included.

The sludge is an organic by-product derived from microorganisms that is inevitably generated in the process of sewage and wastewater treatment using microorganisms. In the activated sludge method, microorganisms grow by ingesting and decomposing organic matter in wastewater, and the microorganisms grown in this way are aggregated and stored in the terminal sedimentation basin. What precipitates out is called sludge.

In order to solve the above problems, various organic waste treatment technologies have been developed to efficiently ferment, dry, and grind organic waste such as impurities and sludge and utilize it as auxiliary fuel.

Looking at the conventional technology, the industry that processes organic waste seeks to improve the efficiency of processing various organic wastes by agitating various wastes with high thermal efficiency and crushing, fermenting, and drying them into powder to enable fuel conversion. A sewage treatment device has been proposed to the Korean Intellectual Property Office under No. 10-0274067.

As described above, the conventional organic waste treatment machine crushes, ferments, and dries the material to be treated, thereby compressing and reducing the weight of the pulverized material so that it can be disposed of or used as auxiliary fuel.

However, during the organic waste treatment process, moisture contained in the organic waste causes agglomeration or agglomerated cakes to form on the wall, which acts as a factor that impedes the efficiency and workability of the crushing, fermentation, and drying treatment of the organic waste.

Therefore, to solve this problem, a new organic waste treatment technology that improves agitation during organic waste treatment and improves efficiency and reliability of operation is required.
