Solar energy-based rotary garden waste composting device

Abstract

The invention discloses a solar energy-based rotary garden waste composting device. The device includes a support system, a rainwater collection system, a composting system and a solar power generation system. The device can move and fix a compost bin as needed, and can detect changes in the physical and chemical indicators in the composting process in order to easily timely adjust the supply of oxygen and water and accelerate the composting process. The device uses the solar power generation system to supply power to a sensor, and provides a water source for the compost bin through the rainwater collection system, so the cost is reduced, the resource utilization rate is improved, and the device is green, and environmentally friendly. A detachable separator plate between a left compostingchamber and a right composting chamber can realize the mixing of materials in the left composting chamber and the right composting chamber in different fermentation stages in order to adjust a carbon-to-nitrogen ratio, the above rotary box body design makes the device realize uncovering-free stirring, avoid the loss of heat and gas, improve the composting efficiency and shorten the 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. has also increased. 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...
