Efficient biogas digester with pressure regulating function

Abstract

The invention relates to an efficient biogas digester with a pressure regulating function. The efficient biogas digester comprises a main body, a feeding port and a cover plate, the efficient biogas digester also comprises a stirring mechanism and a pressure regulating mechanism, wherein the pressure regulating mechanism comprises a pressure regulating tank, an air cylinder, a lifting plate, a pressure sensor and two support assemblies; the stirring mechanism comprises a drive shaft, a first pipeline, a second pipeline, a third pipeline, a rotary joint, a stirring pipe, a drive assembly, a heat storage assembly, an air pump and two mounting bearings; each support assembly comprises a support rod, a limiting block and a support casing; the drive assembly comprises a motor, a first gear anda second gear; and the heat storage assembly comprises a heat storage box and a filter net. In the efficient biogas digester with the pressure regulating function, the probability of crusting of organic fertilizer is reduced by the stirring mechanism, the biogas production efficiency of the biogas digester is improved, the pressure in the biogas digester can be regulated by the pressure regulatingmechanism, so that the pressure in the biogas digester is kept stable, and the combustion efficiency and stability of cookers are improved.

Description

technical field [0001] The invention relates to the field of organic fertilizer production equipment, in particular to a high-efficiency biogas digester with a pressure regulating function. Background technique [0002] Organic fertilizers are also called "farm fertilizers", and those that use organic matter as fertilizers are called organic fertilizers. Including human excrement, manure, compost, green manure, cake fertilizer, biogas fertilizer, etc. It has the characteristics of many types, wide sources and long fertilizer effect. Most of the nutrients contained in organic fertilizers are in an organic state, which is difficult for crops to use directly. Through the action of microorganisms, a variety of nutrients are slowly released, and nutrients are continuously supplied to crops. The application of organic fertilizers can improve the soil structure, coordinate the water, fertilizer, air and heat in the soil, and improve soil fertility and land productivity. [0003]...

AI Technical Summary

Problems solved by technology

[0003] Biogas digesters are the main equipment for biogas fertilizer production. The air pressure inside the biogas digesters of the prior art changes greatly, resulting in unstable gas supply pressure of the biogas digesters, which in turn reduces the efficiency and stability of the stove combustion. Not only that, the existing technology During the use of the biogas digester, the top of the organic fertilizer inside the biogas digester is prone to crusting, which reduces the biogas output of the biogas digester
