Description

Technical Field

[0001] The utility model belongs to the technical field of domestic waste treatment, and in particular relates to a device for making fertilizer by fermenting building and domestic waste. Background Art

[0002] At present, with the development of urbanization, there are more and more buildings, and the domestic waste generated in the buildings is increasing day by day, which brings great difficulties to waste disposal. The food waste in the domestic waste can be fermented to make fertilizer, so as to recycle the food waste. After searching, it was found that the application number "202122691575.0" disclosed "a food waste fertilizer mixing tower", which recorded "including a tower, the tower is composed of a tower outer wall, an insulation layer and a stainless steel lining, the bottom of the lower end of the tower is a hydraulic drive, one end of the stirring shaft in the tower is connected to the top of the tower with a bearing, and the other end is connected to the hydraulic drive; a platform is welded on the top of the tower; one side of the platform is connected to a pedestrian ladder, and the other side is connected to a freight elevator; a feed port is provided at the top of the tower, and the feed port is located at the upper port of the freight elevator; an air pump is also provided at the top of the tower". When the above device is in use The food waste is put into the tower through the freight elevator, and the food waste is stirred by the stirring shaft, so that the waste is fermented to make fertilizer. The above device can greatly reduce the labor intensity of the staff, and the fermentation temperature is kept warm by the provided insulation layer, thereby improving the fermentation efficiency. However, the above device still has certain shortcomings when used: the food waste is directly put into the tower through the freight elevator, and the contact between large pieces of food waste and the air is limited, which affects the fermentation efficiency. At the same time, the above device directly discharges the fermented fertilizer waste through the discharge port. This method causes a large amount of waste to remain in the tower, and when fermenting and making fertilizer, if the temperature is too high, it will affect the fertilizer making effect. At the same time, a large amount of gas will be generated in the tower during the fermentation process. If the gas is not discharged in time, the tower may be damaged due to excessive air pressure.
