Power-free siphon automatic residue discharging system for biogas fermentation tank

Abstract

The invention provides a power-free siphon automatic residue discharging system for a biogas fermentation tank. The power-free siphon automatic slag discharging system is characterized by comprising a fermentation tank, inclined plates, a biogas residue inlet, a residue discharging pipe, a residue discharging valve A, a residue discharging valve B, a back-flushing valve, a back-flushing opening, a sewage draining valve, a sewage draining opening and a residue discharging opening, wherein the bottom of the inner side of the fermentation tank is provided with the inclined plates; the number of the inclined plates is two; and the biogas residue inlet is arranged between the two inclined plates and is connected with the residue discharging pipe. According to the invention, automatic residue discharging of the fermentation tank is realized via siphon action; the inclined plates are mounted on the bottom of the fermentation tank; the biogas residue inlet is arranged between the two inclined plates; the inclined plates gather biogas residues in the fermentation tank to the biogas residue inlet and facilitate flowing of the biogas residues to the biogas residue inlet, so power-free residue discharging is realized; and the residue discharging pipe is connected with a back-flushing pipe, and the back-flushing pipe is provided with the back-flushing valve, so back-flushing water is injected into the fermentation tank from the back-flushing pipe via the back-flushing valve once blockage occurs during residue discharging so as to loosen the biogas residues and to further realize automatic discharging of the biogas residues from the residue discharging pipe.

Description

[0001] technical field [0002] The invention relates to the field of biogas slag discharge, in particular to an automatic slag discharge system without power siphon for a biogas fermentation tank. Background technique [0003] With the development of our country's economy and social progress, the life of urban residents has been further improved, but there are still many problems in the life of rural residents. In order to build a well-off society in an all-round way, the comprehensive utilization of biogas digesters is an important way to change the rural environment. In the traditional use of biogas digesters, the direct discharge method is generally used to discharge biogas residues. However, with the use of biogas digesters, a large amount of biogas residues will accumulate at the outlet, and blockages are likely to occur during slag discharge, resulting in a large amount of biogas residues in the fermentation tank that cannot be discharged. .

In the traditional use of biogas digesters, the direct discharge method is generally used to discharge biogas residues. However, with the use of biogas digesters, a large amount of biogas residues will accumulate at the outlet, and blockages are likely to occur during slag discharge, resulting in a large amount of biogas residues in the fermentation tank that cannot be discharged.
