Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of composting equipment and relates to a composting barrel with good air permeability. Background Art
[0002] A compost bin is a device used to compost organic waste such as kitchen waste and plants. Through proper mixing, ventilation, humidity and temperature control, organic waste is converted into high-quality organic fertilizer. The use of compost bins helps reduce waste disposal costs and environmental pollution, while providing high-quality fertilizer that is beneficial to plant growth.
[0003] The principle of composting in a compost bin is that organic waste is decomposed by bacteria and fungi under suitable conditions. Ventilation is one of the important factors affecting the composting effect. It can provide oxygen, regulate the temperature and humidity in the compost bin, and help remove odors.
[0004] The common compost barrels on the market generally include a barrel body and a barrel lid. The barrel lid is closed on the opening on the top of the barrel body. After the barrel lid is closed, a relatively closed space is formed between the barrel body and the barrel lid. This type of compost barrel is used for anaerobic fermentation. When using it, just close the tank tightly. However, the conversion of substances in anaerobic fermentation is slow and it will produce odor, which is not friendly to the living environment.
[0005] Aerobic fermentation has high material conversion efficiency, mainly produces CO2 and H2O, and is environmentally friendly. At present, there is a lack of a composting barrel for aerobic fermentation on the market. Aerobic composting barrels require ventilation, and existing sealed composting barrels are not suitable.
