Livestock and poultry manure stirring fermenting device capable of reducing peculiar smell

Abstract

The invention discloses a livestock and poultry manure stirring fermenting device capable of reducing peculiar smell. The livestock and poultry manure stirring fermenting device capable of reducing peculiar smell comprises a material storing tank and a stirring tank; the stirring tank is arranged on the top of the material storing tank; a gas outlet screen cylinder is arranged on a transverse shaft in the middle part of the stirring tank; the external side of the gas outlet screen cylinder is provided with a plurality stirring rods; a plurality of stirring blades are arranged on the transverseshaft on the left side and the right side of the gas outlet screen cylinder; the left end of the transverse shaft is connected with a gas inlet pipe through a rotating joint, and the other end of thegas inlet pipe is connected with an air blower; a wind inducing hopper and a filtering tank are arranged o the right side of the stirring tank; in the internal side of the wind inducing hopper, fan blades are arranged on the transverse shaft; a plurality of branched gas pipes are arranged on the top of the stirring tank; the upper end of each branched gas pipe is communicated with a gas exhaust pipe, and the other end of the gas exhaust pipe is designed to stretch into the lower part of the internal side of the filtering tank. The livestock and poultry manure stirring fermenting device can beused for manure processing with less peculiar smell, is capable of avoiding environment pollution, and is widely used for processing of animal manure in culturing farms, and processing of human manure and organic matters in city and town dumping ground.

Description

technical field [0001] The invention relates to the field of manure treatment, in particular to a stirring and fermenting device for livestock and poultry manure that reduces peculiar smell. Background technique [0002] Livestock and poultry manure mainly refers to a type of rural solid waste produced in the livestock and poultry breeding industry, including pig manure, cow manure, sheep manure, chicken manure, duck manure, etc. [0003] Livestock and poultry manure has always been regarded as an important source of soil fertilizer, so most of the livestock and poultry manure is applied on the spot. According to statistics in 1976, at that time more than 1 / 3 of the fertilizers in my country's agricultural production were provided by animal manure. Animal excrement is rich in organic matter and nutrients such as nitrogen, phosphorus, and potassium, and can also supply calcium, magnesium, sulfur, and other minerals and trace elements required by crops to meet the needs of va...

AI Technical Summary

Problems solved by technology

Over-concentrated animal husbandry has led to excessive production of livestock and poultry manure in some areas, which cannot be absorbed by traditional fertilization methods, and a large amount of stacking has caused serious pollution to the atmosphere, soil and water environment

On the other hand, due to the rapid development of the chemical fertilizer industry, people use a large amount of chemical fertilizers, so that a large amount of organic manure is left idle, and the basic nutrients of the soil gradually decline in some places.
