Composting reactor for quickly, efficiently and harmlessly treating livestock manure

Abstract

The invention relates to a compost reactor for quickly, efficiently and harmlessly treating livestock manure, comprising a cylindrical fermenter which is divided into an upper fermentation chamber anda lower equipment chamber, wherein a feed port and a gas outlet are formed in the top of the fermentation chamber, a discharge port and a discharge valve are formed in the side face of the fermentation chamber, a heating coil tube surrounding the inner wall of the fermentation chamber is arranged on the inner wall, a liquid inlet end and a liquid outlet end of the coil tube are connected to a high temperature circulating oil bath tank located in an equipment chamber, three stirring motors and air pump are arranged in the equipment chamber, the three stirring motors drive three stirring rods to rotate, the three stirring rods are distributed in an equilateral triangle, each stirring rod is provided with a plurality of layers of stirring blades, three stirring blades are arranged on each layer, an angle of 120 degrees is formed between the stirring blades of the same layer, the stirring blade layers of the three stirring rods are distributed in a staggered manner, the stirring rods andthe stirring blades both are of hollow structures and communicated with each other, and an air outlet of the air pump is communicated to the bottoms of the three stirring rods by the air outlet, and aplurality of air outlet holes are formed in the stirring blades.

Description

technical field [0001] The invention relates to a device for quickly and efficiently treating livestock and poultry manure, in particular to a composting reactor for harmlessly treating livestock and poultry manure, which belongs to the technical field of livestock and poultry manure treatment. Background technique [0002] my country's livestock and poultry breeding industry has developed rapidly in recent years, large and medium-sized farms have emerged continuously, and livestock and poultry waste cannot be recycled in the breeding concentrated areas, resulting in regional pollution. How to process and utilize waste into treasure as soon as possible has become an urgent problem to be solved. [0003] Traditional livestock and poultry manure composting is simply composting livestock and poultry manure and returning it to the field after natural fermentation. This method is generally one-time fermentation, mostly open-air stacking, completely relying on natural oxygen supp...
