Vertical type multi-layer aerobic biological composting device

Abstract

The invention relates to a composting device and discloses a vertical type multi-layer aerobic biological composting device. The vertical type multi-layer aerobic biological composting device comprises a vertical cylinder, wherein a sealing cover is arranged on the top of the vertical cylinder, a feeding hopper is arranged on the sealing cover, a plurality of partition plates are vertically distributed in the vertical cylinder and are used for dividing the vertical cylinder into a plurality of partition layers, and a blanking door is arranged on each partition layer; a rotary shaft which simultaneously penetrates through the sealing cover and the partition plates is vertically arranged, a drive motor is arranged on the outer end part of the rotary shaft, and a plurality of stirrers corresponding to the partition layers are arranged on the rotary shaft. An air feeding tube which is communicated with the partition layers simultaneously is arranged at one side of the outer part of the vertical cylinder, and an air extracting tube which is communicated with the partition layers simultaneously is arranged at the other side of the outer part of the vertical cylinder. The device can be used for recycling various urban and rural organic solid wastes, the floor space of the composting device is reduced, and the device has important theoretical and practical significance in guaranteeing the urban environment to be beautiful and promoting the development of regional economy.

Description

technical field [0001] The invention relates to a composting device, in particular to a vertical multi-layer aerobic biological composting device. Background technique [0002] Composting is the use of microbial decomposition technology to degrade various degradable organic wastes into a stable organic fertilizer product suitable for soil fertilization and environmental restoration. According to data, various organic solid wastes in urban and rural areas in my country amount to tens of millions of tons. If they are not used rationally, it will not only cause a large waste of resources, but also cause secondary pollution of the environment. [0003] Taking municipal sludge as an example, by March 2014, my country had operated more than 3,000 urban sewage treatment plants. It produces about 35 million tons of sludge with a water content of 80% every year; it is estimated that there will be more than 4,000 urban and rural sewage treatment plants in the near future, and more th...

Problems solved by technology

However, the current situation of sludge disposal in my country is as follows: about 20% is safely landfilled; about 10% is made into fertilizer by composting and returned to farmland; a small amount is incinerated into energy or smelted into building materials, and most of the rest is Simple landfill or stacking, which occupies a large amount of farmland, also brings great hidden dangers to the ecological environment
