Fermenting and drying treatment device for organic wastes

Abstract

The invention discloses a fermenting and drying treatment device capable of reliably and effectively fermenting and drying organic wastes with simple structure for avoiding cost increment. The device is provided with an airtight container, a hollow cylindrical rotating shaft rotating freely and vertically arranged in the container, a plurality of stirring blades extending to the horizontal direction from multiple upper and lower positions of the rotating shaft, a driving mechanism for driving the rotating shaft to rotate, an air supply mechanism for supplying air to the container, and an exhaust port for exhausting the air in the container. The plurality of stirring blades comprises stirring blades which have hollow interiors and are provided with through holes communicating the outside from the hollow space, the air supply mechanism is connected at the axial end of the rotating shaft, and the hollow space of the rotating shaft is mutually communicated with the hollow space of the stirring blades. Therefore, the air supplied by using the air supply mechanism is exhausted from the through holes of the stirring blades through the rotating shaft. The organic wastes are put into the container, the air is introduced into the container, the organic wastes are stirred, and the organic wastes are subjected to fermenting treatment and drying treatment based on the action of aerobic microbes.

Description

technical field [0001] The invention relates to a fermentation and drying treatment device which utilizes the action of aerobic microorganisms to aerate and stir organic wastes such as livestock dung in an airtight container to ferment and dry them. Background technique [0002] Conventionally, organic waste such as animal manure and food scraps has been composted (composted) and reused. As composting treatment, there are generally accumulation type and mechanical stirring type. The stacking method refers to the method of mixing moisture-regulating materials such as rice bran with organic waste to adjust to an appropriate moisture content, and stacking it for natural fermentation. The mechanical stirring method refers to the method of using a stirring device to stir the organic waste to promote its aerobic fermentation, and the fermentation heat at this time is also used to evaporate the water in the organic waste. Among them, the mechanical stirring type has an open stirr...
