Dustchute - Dustchute (English spelling)

Japanese: ダストシュート - だすとしゅーと(英語表記)dustchute
Dustchute - Dustchute (English spelling)

A device that drops waste down a vertical tube and accumulates it at the bottom. The vertical tube is made of concrete, steel, or stainless steel pipes with a diameter of 30 to 60 centimeters. Some types of waste inlet have a limited capacity for one inlet. Auxiliary equipment includes a waste level detector, ventilation system, automatic fire extinguisher, and cleaning/disinfection system. A waste storage tank is installed at the bottom of the tube, and some types connect to an incinerator and some load waste onto a dump truck. There are also types that connect to a vacuum horizontal transport pipe. The inlet must be airtight when closed, and when open, an internal shutoff plate must close to prevent air from escaping from the tube.
