Sealing structure of fermentation box in methane generating device

Abstract

The invention provides a sealing structure of a fermentation box in a methane generating device, belonging to the technical field of methane fermentation and solving the technical problems that the fermentation efficiency is reduced because air is easily mixed in the fermentation box when a leavening is added, and the like in an existing methane generating device. The methane generating device comprises a methane collecting box, a fermentation box and a feeding hopper, wherein a collecting cavity is formed between the fermentation box and the methane collecting box, a spherical cavity is formed in the middle of the fermentation box, the bottom of the fermentation box is also communicated with a material discharging pipe and a liquid discharging pipe, and the other ends of the material discharging pipe and the liquid discharging pipe penetrate through the methane collecting box and then are communicated with outside. The sealing structure of the fermentation box in the methane generating device comprises a sealing door I which is arranged on the outer side wall of the fermentation box and capable of opening or closing the feeding hopper and a sealing door II which is arranged on the inner side wall of the fermentation box and capable of enabling the cavity to be communicated or separated from the feeding hopper, and the sealing door II is positioned in the cavity. According to the sealing structure, air is unlikely to be mixed when the leavening is added.

Description

technical field [0001] The invention belongs to the technical field of biogas fermentation, and relates to a biogas generator, in particular to a sealing structure of a fermentation box in the biogas generator. Background technique [0002] As a clean energy, biogas has been widely used in various fields by human beings. The main raw material of biogas is crops such as straw. Because of the wide sources of such crops and the large amount of resources, the content of biogas is also very rich. At present, a large amount of crop waste such as straw has not been effectively treated, which has brought a series of environmental problems and seriously threatened the development of human beings. This problem can be effectively solved by biogasizing crop waste such as straw, and at the same time, high-quality bioenergy—"biogas" can be produced, which has very high economic value. [0003] At present, there are many biogas generating devices developed by human beings, but all of the...

Problems solved by technology

Although this patented product can carry out anaerobic fermentation, it cannot ensure that the fermentation chamber is isolated from the outside world when cleaning up the residue after fermentation and re-adding the fermented product during production, and it is easy to mix in impurities such as air, which will cause no fermentation. Continuous, and the continuous mixing of air in the fermentation room will also lead to a decrease in fermentation efficiency
