Pig manure conversion and utilization device with dry-wet separation function

Abstract

The invention discloses a pig manure conversion and utilization device with a dry-wet separation function. The pig manure conversion and utilization device comprises a treatment device, a dehydrationdevice, a dry material box, a fermentation tank, a cyclone separator, a crushing device, a second spiral feeding machine, a first spiral feeding machine, an annular guide rail and an electric trolleybase. According to the pig manure conversion and utilization device with the dry-wet separation function, accurate temperature regulation and control in the anaerobic fermentation tank can be achieved, the anaerobic fermentation speed is effectively increased, pathogenic bacteria in pig manure can be killed through high temperature, and organic matter containing a large amount of cellulose, ligninand other degradation-resistant components in live pig manure can be ground into powder, so that the anaerobic fermentation effect of the live pig manure can be effectively improved, moisture in thelive pig manure can be preliminarily separated through the pretreatment device, clustered live pig manure can be effectively scattered, and the live pig excrement can be effectively dehydrated throughthe dehydration device.

Description

technical field [0001] The invention relates to the technical field of breeding waste treatment, in particular to a pig manure conversion and utilization device with a dry-wet separation function. Background technique [0002] With the continuous development of our country's economy and society, the living standard has improved rapidly, and the residents' demand for meat and eggs has also increased rapidly. The domestic livestock and poultry breeding industry has developed rapidly and tended to be stable. The output of pork has reached 52.99 million tons , Accounting for 45.5% of the world's total, the livestock and poultry breeding industry has gradually become the most active growth point and the main pillar industry in my country's agricultural economy. However, with the improvement of the intensification of farms, the separation of the farms from the planting industry, the large amount of manure has nowhere to be consumed, and the disorderly discharge of aquaculture waste...

AI Technical Summary

Problems solved by technology

However, the existing anaerobic fermentation has the following problems: First, in the process of pig manure fermentation, three processes of low-temperature fermentation, medium-temperature fermentation and high-temperature fermentation are generally required, and the existing anaerobic fermentation tanks cannot achieve precise temperature control

However, pig manure contains a large amount of organic matter such as wood fiber and other refractory components, which leads to a decline in the effect of anaerobic fermentation of pig manure; in addition, the existing anaerobic fermentation of pig manure is limited by the fermentation temperature, resulting in pathogenic bacteria contained in pig manure. more residual
