Abstract

The invention discloses a rotary yard waste composting device based on solar energy. The installation includes a support system, a rainwater collection system, a composting system and a solar power generation system. The device can move and fix the position of the compost bin as needed, and can detect changes in physical and chemical indicators during the composting process, so as to facilitate timely adjustment of oxygen and water supply and speed up the composting process. At the same time, the present invention uses a solar power generation system to supply power to the sensor, and provides water sources for the compost bin through the rainwater collection system, thereby reducing costs, improving resource utilization, and being environmentally friendly. At the same time, the disassembled partitions in the middle of the left and right composting chambers can realize the mixing of materials in different fermentation stages of the left and right composting chambers, thereby adjusting the carbon-nitrogen ratio, and adopt a rotatable box design, without opening the lid for stirring, avoiding heat and gas loss. , Improve composting efficiency and shorten composting cycle.

Description

technical field [0001] The invention relates to the composting bin technology, in particular to a solar energy-based rotary yard waste composting device. Background technique [0002] With the continuous development of urban greening, the amount of garden waste produced in the city, such as the residues produced by the natural fall of garden plants or artificial pruning, including leaves, grass clippings, branches, residual flowers and fruits, etc. is also increasing. According to statistics, the annual output of garden waste in Beijing, Shanghai, Guangzhou and other places is more than 100,000 tons, while the European Community countries produce more than 1.25 billion tons of garden waste every year. Garden waste contains a certain amount of beneficial nutritional elements, a large amount of lignin, cellulose and hemicellulose, and some organic substances. Moreover, compared with urban sludge and other domestic waste, garden waste has less raw material pollution and does no...
