Description

Dehydrator

The present invention relates to a dehydrator, and more particularly, to a dehydrator for dehydrating a dehydration object such as livestock manure.

Livestock manure has become a major cause of environmental pollution due to the large amount of livestock manure, which is increased with the increase of population and the development of industrialization. That is, the discarded waste is badly odor generated as it is decomposed, and the regenerating pathogen adversely affects human health and hygiene directly or indirectly, and also pollutes the water supply.

Accordingly, efforts are being made to develop various and eco-friendly technologies for solving the complaints caused by composting of solid components, purification of liquid components, and odor problems with the surroundings.

Korean Patent Laid-Open Publication No. 10-2016-0035312 discloses a solid-liquid separation device for livestock manure, in which a transfer screw is mounted inside a rotating drum to simultaneously perform dehydration by centrifugation and compression.

However, there is a concern that the solid-liquid separator of livestock manure may be discharged to the outside in a state in which dehydration is not completed because the dewatering object such as livestock manure is continuously transferred to the discharge part by a transfer screw. In addition, the solid-liquid separator is a risk that the liquid discharged while the rotating drum is rotated back into the rotating drum.
