Small novel composting device and control method thereof

Abstract

The invention discloses a small novel composting device and a control method thereof. The composting device comprises a composting chamber, a heat retaining shell and a controller, the composting chamber is arranged inside the heat retaining shell, a heating band is arranged on the outer wall of the composting chamber, a cavity B is formed in the bottom of the composting chamber and communicated with the outside through an air inlet pipeline, an air flowmeter and solenoid valves are connected to the end, located outside the heat retaining shell, of the air inlet pipeline, an air outlet pipeline is arranged at the top of the heat retaining shell, absorption bottles are connected to the end, located outside the heat retaining shell, of the air outlet pipeline; temperature sensors are further arranged in the composting chamber, the heat retaining shell comprises a shell body and a shell cover, the shell cover is located on the top of the shell body, and the inner surface of the shell cover is gradually inclined downwards from the middle to the edge. According to the small novel composting device and the control method thereof, the structure is simple, use is convenient, various data can be simultaneously monitored, recorded and analyzed, the composting device is maintained to run under the best condition through feedback control, therefore, the composting efficiency is improved, and pollution to the surrounding environment is reduced.

Description

technical field [0001] The invention relates to a fertilizer production equipment, in particular to a small new composting device and a control method thereof. Background technique [0002] Composting is the process of using microorganisms and enzyme activity to accelerate the biodegradation and transformation of organic matter under controlled aerobic conditions, and finally make the organic matter decompose and stabilize. The composting process can not only reduce the volume, weight, and odor of organic solid waste, kill pathogenic bacteria, insect eggs, plant seeds, etc., but also produce a large amount of humus. The produced compost products can be used as soil conditioner and plant nutrient source, which can effectively improve soil structure and improve soil fertility. At present, composting technology has been widely used in the treatment of excess sludge, livestock and poultry farming waste, municipal waste, kitchen waste, yard waste, etc. [0003] There are many p...

AI Technical Summary

Problems solved by technology

In addition, the traditional small-scale composting reactor can not effectively reduce the moisture (due to the degradation of organic matter, the moisture cannot be discharged and the moisture content of the material is too high, etc.), it is easy to lead to anaerobic composting environment, which is not conducive to the maturity of compost and is easy to discharge NxO, methane and other greenhouses gas
