Annular fermentation tank capable of continuously turning and throwing livestock and poultry manure

Abstract

The invention discloses an annular fermentation tank capable of continuously turning and throwing livestock and poultry manure, which comprises a closed annular tank body, wherein a turning and throwing machine is arranged in the annular tank body; an inner ring traveling wheel and an outer ring traveling wheel are arranged on the turning and throwing machine; an inner ring traveling channel and an outer ring traveling channel are respectively arranged on the annular tank body; a turning and throwing roller is arranged on the turning and throwing machine; turning and throwing teeth are arranged on the turning and throwing tank, an aeration device is arranged at the bottom of the annular tank body; a feeding port and a discharging port are sequentially arranged in the traveling direction ofthe turning and throwing machine; an exhaust device is arranged on the annular tank body; the turning and throwing machine uses double turning and throwing rollers and moves in a circular manner; theturning and throwing machine can fully turn and throw the livestock and poultry manure; and livestock and poultry manure are completely are turned and thrown from the feeding port to the dischargingport; automatic discharging can be achieved. The aeration device in the annular tank can ensure the oxygen needed for fermentation, and an exhaust device can carry away the evaporated water vapor andodor for harmless treatment of exhaust gas; according to the invention, fully-mechanized operation can be achieved and a complete aerobic fermentation system is achieved, the promotion value is high.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry manure fermentation, in particular to a fermentation tank. Background technique [0002] my country is a large livestock and poultry breeding country, with an annual output of about 3.8 billion tons of livestock and poultry manure. If it is not handled in time or properly, it will easily cause a large number of environmental problems such as flies, air pollution, water pollution, and biological pollution. The impact of these environmental problems The scope and depth have exceeded the extent of industrial pollution and urban expansion. [0003] The country has listed livestock and poultry waste treatment and resource utilization as the top priority of agricultural non-point source pollution control. One of the effective measures for the treatment and resource utilization of livestock and poultry waste is to ferment livestock and poultry manure to produce organic fertilizer and then r...

Problems solved by technology

However, most of the existing fermentation tanks are open-air fermentation, which is difficult to form high temperature, has poor decomposing effect and cannot completely control the odor; at the same time, the fermentation tanks that can form a scale often have a long length, occupy a large site, and the construction is cumbersome; There are problems such as excessively high local stockpiling and poor discharge, and it is often necessary to intersperse manual operations, perform partial turning and help discharge, etc., which makes the use of the fermentation tank poor.
