Efficient and energy-saving continuous type composting fermentation device

Abstract

The invention discloses an efficient and energy-saving continuous type composting fermentation device. The composting fermentation device comprises a pre-treatment device, a composting fermentation device and a transmission device, wherein after composting raw materials and a conditioner are pre-treated and uniformly mixed, the mixture is conveyed to the composting fermentation device; when the transmission device is used for driving a scraping blade fixed on a stirring shaft connecting rod of the composting fermentation device to overturn the composting raw materials and the conditioner to get close to a thin-layer composting material of a cabin wall of a composting cabin, air exchange is finished through a ventilation hole formed in the inclined lower side of the composting cabin; the composting material is pushed to move in a direction from a feeding opening to a discharging opening; the composting fermentation device adopts a continuous or intermittent and continuous feeding mannerand the staying time of compositing material in the composting cabin is 5 to 8 days; each layer of the compositing material can be in contact with air by adopting a composting manner, with relativelylow driving power, so that the oxygenation efficiency is improved; first-phase compositing is finished in relatively short time and automatic continuous feeding and discharging can be realized; the compositing efficiency is improved and the operation cost and the labor cost of equipment are reduced; the efficient and energy-saving continuous type composting fermentation device is suitable for being popularized and applied to most of village and town regions with continuous production of organic solid wastes and less output in China.

Description

technical field [0001] The patent of the invention belongs to the field of organic solid waste treatment technology and its resource utilization, and specifically relates to a high-efficiency and energy-saving continuous composting fermentation device. Background technique [0002] With the increase of population, the output of organic solid waste in villages and towns is also increasing year by year. In order to avoid secondary pollution and effectively utilize the active ingredients, its treatment method has become a concern of the whole society; high-temperature aerobic composting technology can realize The harmless treatment and resource utilization of waste are widely used; the current composting methods are mainly divided into strip stacking and reactor type. Strip stacking composting is suitable for large-scale composting plants, and the processing volume of organic waste is large, and the operating cost Low, but it requires a lot of free land, the process conditions ar...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the patent of the present invention is to provide a high-efficiency composting device for the problems of high electromechanical energy consumption of compost turning in the above-mentioned existing compost fermentation device, energy waste caused by overall turning of compost, high cost of oxygen aeration and aeration, and inability to realize automatic continuous production. An energy-saving continuous composting fermentation device. This device uses the ventilation holes opened on the lower volume of the composting bin wall for air exchange to reduce ventilation energy consumption; it uses a scraper that is close to the composting bin wall and has a certain angle to turn the material, and the device is low in cost. , suitable for promotion and use in areas where organic waste is continuously produced in villages and towns in my country
