Description

Technical Field

[0001] The utility model relates to the technical field of fermentation reactors, in particular to a livestock and poultry excrement fermentation reactor capable of automatically controlling temperature and removing water. Background Art

[0002] Poultry and livestock manure can be used as raw materials for making organic fertilizers and organic-inorganic compound fertilizers. Currently, the technologies for producing fertilizers from livestock and poultry manure mainly include reactor fermentation and trough composting. Compared with trough composting, reactor fermentation has the characteristic of a high degree of automation.

[0003] During the fermentation of livestock and poultry manure, stirring can control the temperature and water content of the material during the fermentation process. Aeration can achieve stable oxygen supply, increase the degradation rate of organic matter, shorten the fermentation composting time, and improve production efficiency. Waste gas collection can reduce the generation of odor. At present, the fermentation reactors on the market have the problem of condensed water inside the reactor affecting the solid-liquid ratio of the material.

[0004] In order to solve the above problems, the prior art proposes a livestock and poultry manure fermentation reactor that can automatically control temperature and remove water. The composite device of the screw agitator and the guide tube adopted in the reactor can make the materials inside and outside the guide tube flow in the opposite direction, thereby achieving uniform heating and uniform aeration, and improving the stirring efficiency and fermentation effect. At the same time, the water bath heating system adopted can maintain the optimal fermentation temperature, and the condensed water is discharged out of the reactor through the drainage trough adopted, thereby avoiding the condensed water from affecting the solid-liquid ratio of the material. Although it is convenient to reduce the influence of the condensed water inside the reactor on the solid-liquid ratio of the material, when the material enters the guide tube through the feed port, large pieces of material are prone to blockage when moving up in the guide tube, which is easy to reduce the material upward movement efficiency, thereby easily reducing the circulation flow effect of the material at the bottom of the reactor.
