Livestock and poultry manure anaerobic fermentation equipment

Abstract

The invention discloses livestock and poultry manure anaerobic fermentation equipment which structurally comprises a support, a machine body, a top cover, a leavening agent inlet pipe and an exhaust fan, and the top surface of the support is connected with the bottom surface of the machine body in a welded mode. An internal rotating rod is driven by a motor, and water and a leavening agent are added after excrement of herbivorous animals such as cattle, sheep, elephants and the like is added, firstly, the excrement is rapidly cut through a cutter structure on a cutting block, fibrous matter difficult to ferment in the excrement is cut into small sections, the excrement is dispersed, the excrement makes contact with the fermenting agent more completely, then excrement liquid moves towards the rotating rod through a concentrating shell, most of fibers in the excrement liquid are collected by a collecting rod, and the rest small part is collected by an edge backflow plate arranged on theouter surface of the centralizing shell so that suspended fibrous materials which are difficult to ferment in the excrement are attached and fixed, the fermentation effect is better, the adhesion of the dried fermentation product after the fermentation is finished due to the fibrous materials is avoided, and the collection and the dicing separation are more convenient.

Description

technical field [0001] The invention relates to anaerobic fermentation equipment, in particular to anaerobic fermentation equipment for livestock and poultry manure. Background technique [0002] Animals will produce manure after digestion, which contains a large amount of organic matter. After fermentation, these organic matters can be used to fertilize farmland. Usually, anaerobic fermentation is used for fermentation, which can not only effectively ferment manure, but also produce Combustible gas, to further enhance the utilization rate. The existing anaerobic fermentation equipment is used in zoos. When fermenting the feces of cattle, sheep, elephants and other animals, because these herbivores have weak ability to digest fiber, the plants in the feces The content of fiber and semi-fiber is high. Since plant fiber and semi-fiber are difficult to be completely fermented during anaerobic fermentation, it is easy to cause poor fermentation effect during fermentation. At the...

[0002] Animals will produce manure after digestion, which contains a large amount of organic matter. After fermentation, these organic matters can be used to fertilize farmland. Usually, anaerobic fermentation is used for fermentation, which can not only effectively ferment manure, but also produce Combustible gas, to further enhance the utilization rate. The existing anaerobic fermentation equipment is used in zoos. When fermenting the feces of animals such as cattle, sheep, elephants, etc., because these herbivores have weak ability to digest fiber, the plants in the feces The content of fiber and semi-fiber is high. Since plant fiber and semi-fiber are difficult to be completely fermented during anaerobic fermentation, it is easy to cause poor fermentation effect during fermentation. At the same time, it is easy for fibers to stick together after fermentation, which is not convenient for fermentation. Product collection and dicing
