When the biogas needs to be produced: firstly, a feed valve is opened, biogas raw materials and biogas fermentation microorganisms are conveyed from a feed pipe 2 to the bottom of a tank body 1, and the feed valve is closed after the biogas raw materials and the biogas fermentation microorganisms are conveyed. Then, the feeding cover plate 34 is opened, a layer of biogas raw material and biogas fermentation microorganisms are laid on the microorganism enrichment plate 9 from the feeding window 403 of the sealing cover 4, and the feeding cover plate 34 is closed after the laying. Then, the biogas raw material standing at the bottom of the tank body 1 and the biogas raw material laid on the microorganism enrichment plate 9 are decomposed and fermented by the biogas fermentation microorganisms to generate biogas, and the generated biogas flows out from the biogas pipe 5 and is collected.

Along with the continuous fermentation of the biogas raw materials, the biogas raw materials standing at the bottom of the tank body 1 can be layered, and sequentially comprise a sediment layer, an active layer, a supernatant layer and a scum layer from bottom to top. The biogas in the active layer is fermented by more microorganisms, but the biogas raw material is less, and the biogas raw material is not enough to generate biogas. The biogas fermentation microorganisms and biogas raw materials in the supernatant layer are fewer. The biogas raw material in the scum layer is more, but the biogas fermentation microorganisms are less, so that the biogas raw material in the scum layer is not fermented sufficiently.

For this reason, a stirring mechanism is required to stir the biogas raw material in which the stratification phenomenon occurs. On one hand, the biogas raw materials which have the layering phenomenon are fully mixed, so that the biogas raw materials in the scum layer can be fully contacted with biogas fermentation microorganisms in other layers (an active layer and a clear liquid layer), the utilization efficiency and the fermentation efficiency of the biogas raw materials in the scum layer are improved, and the production efficiency of biogas is improved. On the other hand, the biogas in the supernatant layer and the active layer below the scum layer can flow upwards, so that the phenomenon that the biogas in the supernatant layer and the active layer below the scum layer cannot flow upwards due to blockage of the scum layer is avoided, and the biogas collection efficiency is improved.

Specifically, the method comprises the following steps: when the biogas raw materials at the bottom of the tank body 1 need to be stirred: the staff starts the motor 20, the output shaft of the motor 20 rotates, the driving gear 21 fixed with the output shaft of the motor 20 in a welding mode rotates, the driven gear 22 matched with the driving gear 21 rotates, the stirring shaft 18 fixed with the driven gear 22 in a welding mode rotates in the stirring hole 402 of the sealing cover 4, the supporting ring 23 fixed with the stirring shaft 18 in a welding mode rotates on the upper end face of the sealing cover 4, the blade 19 fixed with the stirring shaft 18 in a welding mode rotates, and in the rotating process of the blade 19, the rotating blade 19 can stir the methane raw materials with the layering phenomenon at the bottom of the tank body 1.

In addition, because the survival and the propagation of the biogas fermentation microorganisms are suitable and unfit, if the biogas fermentation microorganisms are stirred frequently, the survival and the propagation of the biogas fermentation microorganisms are interfered, so the stirring times are reduced as much as possible. During the period that the biogas raw materials are not stirred, as the microorganism enrichment plate 9 is covered with the biogas raw materials and the biogas fermentation microorganisms, the biogas fermentation microorganisms and the decomposed biogas raw materials can fall on the scum layer along with the continuous propagation of the biogas fermentation microorganisms, and the biogas fermentation microorganisms are supplemented to the scum layer, so that the biogas raw materials in the scum layer are fermented more fully, the utilization efficiency and the fermentation efficiency of the biogas raw materials in the scum layer are improved, and the production efficiency of biogas is improved.

Therefore, the biogas generator with the built-in microorganism enrichment mechanism is particularly suitable for occasions with few stirring times of biogas raw materials, even no stirring of the biogas raw materials, and needs to improve the fermentation efficiency of the biogas raw materials in the scum layer and the production efficiency of biogas.

In addition, according to the methane generator with the built-in microorganism enrichment mechanism, the microorganism enrichment mechanism is arranged at the upper part of the tank body, so that the space utilization efficiency of the inner cavity of the tank body 1 can be improved, the treatment capacity of methane raw materials is improved, and the methane production is improved.

Moreover, the microorganism enrichment plate 9 is arranged between the inner ring 7 and the outer ring 8, and the microorganism enrichment plate 9 can be positioned right above the scum layer at the bottom of the tank body 1, so that methane fermentation microorganisms and decomposed methane raw materials on the microorganism enrichment plate 9 can more uniformly fall on the scum layer at the bottom of the tank body 1, further methane raw materials in the scum layer are more fully fermented, the utilization efficiency of the methane raw materials is further improved, and the production efficiency of methane is further improved.

When the biogas raw material is fermented, residues which cannot be fermented are left at the bottom of the tank body 1 and on the microorganism enrichment plate 9, and the tank body 1 needs to be cleaned at the moment.

During cleaning: firstly, the staff starts the first electric push rod, the first electric push rod extends, the extended first electric push rod pushes the sleeve 13, the adjusting rod 12 positioned in the sleeve 13 inclines from the adjusting long hole 401 in the direction away from the first electric push rod, the vertical rod 10 welded and fixed with the adjusting rod 12 also inclines along with the adjusting rod 12, all the vertical rods 10 incline because the upper ends of two adjacent vertical rods 10 are hinged through the cross rod 11, the microorganism enrichment plate 9 welded and fixed with the lower end of the vertical rod 10 can rotate by taking the rotating rod 6 as a rotation center to incline, and after the microorganism enrichment plate 9 inclines, residues positioned on the upper end face of the microorganism enrichment plate 9 slide to the bottom of the tank body 1. Then, the staff opens the bleeder valve, from discharging pipe 3 with the pump with the residue of the bottom of jar body 1 can, clear up the back, close the bleeder valve.

Can know through the above-mentioned clearance process to jar body 1: through setting up first electric putter, sleeve 13, regulation pole 12, pole setting 10, horizontal pole 11, bull stick 6, can conveniently clear up the residue that covers on microorganism enrichment board 9, and then make the clearance of jar body 1 more convenient, improved cleaning efficiency for the marsh gas generator of a built-in microorganism enrichment mechanism of this embodiment 1 maintains more conveniently, has improved maintenance efficiency.
