DEVICE FOR INTEGRATING BAG-BREAKING, SCREENING AND DRYING OF HOUSEHOLD WASTE

WIPO Patent Application WO/2017/035924

A1

A device for integrating bag-breaking, screening and drying of household waste comprises a screening drum, a power unit and a support device. The screening drum is mounted on the support device, has a discharging end tilted downward by a certain angle, and is provided with power gears (9) on an outer circumferential surface thereof. The power gears (9) are connected to the power unit. The discharging end of the screening drum is connected to a gasification furnace (16) via a burner (15). An internal cavity of the screening drum is sequentially divided into a first bag-breaking region (2), a first screening section (6), a second bag-breaking region (7), a second screening section (8) and a drying region (11) from a feeding end to the discharging end. The first bag-breaking region (2) and second bag-breaking region (7) are provided with n shredding knives (3) on internal walls thereof. Several small circular holes distribute on the drum walls of the first screening section (6) and second screening section (8). The device performs bag-breaking and screening on waste, and utilizes the heat generated by gasification of dry waste for drying waste having a higher humidity, thus enabling actual practicability.
