Aeration-overturning integrated machine

Abstract

The invention discloses an aeration-overturning integrated machine, belonging to the field of composting equipment. The aeration-overturning integrated machine comprises a U-shaped base and a cambered hood arranged above the U-shaped base, wherein a spiral propeller is arranged in the cambered hood; the spiral propeller comprises a hollow main shaft and helical blades on the main shaft; both ends of the main shaft extend out of the cambered hood; one end of the main shaft is connected with a motor through a speed reducer, and the other end is connected with a blast pipe through a bearing; the blast pipe is connected with a blower; a feed hopper, an exhaust pipeline and a dosing pipe are sequentially arranged above the cambered hood; the lower part of one end of the U-shaped base adjacent to the blast pipe is provided with a discharge hopper; the main shaft positioned between the feed hopper and discharge hopper is provided with an aeration hole; and an aeration head is arranged on the aeration hole. The aeration-overturning integrated machine can simultaneously implement the overturning and aeration processes, satisfies the ventilatory capacity demand, enables the oxygen in the material to be uniformly distributed, saves the energy, and keeps the optimized operation of the system. The overturning is utilized to increase the clearance in the material, and does not need fallen leaves, chaffs, straws or the like as the auxiliary filler.

Description

technical field [0001] The invention belongs to the field of composting equipment, and in particular relates to an integrated machine for aeration, turning and throwing. Background technique [0002] Aerobic high-temperature composting technology can reduce the volume, weight and moisture of compost raw materials, reduce the odor generated during the decomposition of organic matter, and kill pathogens through the high temperature generated during fermentation. The substances after aerobic high-temperature composting can achieve harmlessness, stabilization and reduction, and can be used as landscaping and agricultural fertilizers to realize the recycling of resources. Composting is suitable for non-fluid and biodegradable wet materials, such as municipal solid waste, municipal sludge, animal manure, agricultural and urban greening waste, etc. [0003] The composting process is a complex biochemical reaction process, which is affected by the initial parameters of composting a...

AI Technical Summary

Problems solved by technology

[0005] In addition, high-temperature aerobic fermentation of sludge often uses fallen leaves, chaff, straw, etc.

At the same time, mechanical turning and throwing composting is mostly open-type treatment such as stacks or fermentation tanks (bins), which have problems such as large investment, high operating costs, air pollution caused by disorderly discharge of toxic and harmful gases, and difficulties in later deep processing, which make the sludge disposal project successful. less than good implementation
