Abstract
The utility model relates to the technical field of structures of biogas digesters, and particularly relates to a circulating biogas digester. The circulating biogas digester comprises a feeding port and a discharging port which are arranged at the upper part of the biogas digester, wherein a sealing top cover is arranged at the upper part of the biogas digester and is provided with an air outlet hole, a stirring device is arranged at the bottom of the biogas digester, a material leaking hole is formed at the bottom of the biogas digester, a spiral convey roller is arranged below the material leaking hole, the feeding end of the spiral convey roller is arranged below the discharging port, an electromotor is arranged at the lower part of the biogas digester, and the electromotor is connected with a reduction box and furthermore used for driving the spiral convey roller and the stirring device. The circulating biogas digester has the following advantages: 1, raw materials are uniformly distributed in the biogas digester; 2, the raw materials stay in the biogas digester for equal time and ferment fully; 3, the materials are easily discharged; 4, only slag at the deslagging port is removed without affecting the reaction in the biogas digester, and biogas can circularly and continuously used.
Description
Technical field
The utility model relates to biomass pool structure technical field, specifically a kind of circulating methane-generating pit.
Background technology
Biomass energy is one of three large new forms of energy, is the important channel that comprehensively solves environmental protection and energy resource supply.But compared with wind energy, sun power, the exploitation of biomass energy obviously lags behind, do not find so far good method.At present, biomass energy exploitation mainly contains direct-fired generating, high-temperature gasification and biogas fermentation technology.Compared with other two kinds of biomass technology, biogas technology has many good qualities: 1. adaptability to raw material is wide; 2. biogas is ecology, environmental protection, the high-quality energy; 3. the by product of biogas can be produced organic fertilizer, is worth very high; 4. biogas technology is simple.Just because of this, biogas technology is widely applied in China.Only, during 11th Five-Year, the Chinese government just invests more than 240 hundred million yuan of construction methane generating pit and technical study.
But biogas technology also exists many problems, cause that biogas technology cannot carry out on a large scale, industrialization and high benefit application.These defects mainly contain: 1, biogas fermentation speed is slow; 2, small scale; 3, invest high; 4, comprehensive benefit is low.Fixed bed methane-generating pit is current conventional biomass pool structure, and its constructional feature is: be made up of sweathouse, storeroom, opening for feed, discharge port, water pressure house, air guide port, discharge port passage.There is following shortcoming in this methane-generating pit: 1, raw material skewness in pond, and there is raw material accumulation in some places, there is raw material cavity in some places; 2, raw material residence time in pond inhomogeneous, the raw material excessive fermentation making, some insufficient fermentations; 3, discharging is very difficult, and particularly for large methane tank, discharging is more difficult; 4, need to stop using after having fermented, clearing up, impact is used continuously.
Summary of the invention
The purpose of this utility model, is exactly the problem existing for solving prior art, and has designed a kind of circulating methane-generating pit, has solved raw material skewness in pond that existing methane-generating pit exists, and raw material residence time in pond is inhomogeneous, the problem that discharging is very difficult.
The technical solution of the utility model is: a kind of circulating methane-generating pit, comprise the feeding port and the discharge port that are arranged on methane-generating pit top, Packed top cover is established in the top of methane-generating pit, and top cover is provided with production well, the bottom of described methane-generating pit is provided with whipping appts, and the bottom of methane-generating pit is provided with material spilling hole; The below of described material spilling hole is provided with helical feed roller, and the feeding end of helical feed roller is arranged on the below of discharge port; The below of described methane-generating pit is provided with electric motor, and electric motor connects step-down gear and drives helical feed roller and whipping appts simultaneously.
The whipping appts of described methane-generating pit bottom is the fixing agitating vane being fixed on rotation axis and the rotation axis of methane-generating pit bottom centre.
The top cover of described methane-generating pit is that transparent toughened glass is made or uses solar panel to form.
The top cover of described solar panel is connected with electric heater, and described electric heater is arranged on the sidewall of methane-generating pit.
Described discharge port is provided with seal cover board.
The beneficial effects of the utility model can draw by such scheme: in sweathouse, have conveyer, make the slag care bottom of methane-generating pit form movably structure, thereby solve the shortcoming that fixed bed methane-generating pit exists, feeding capable of circulation, uses biogas continuously.Therefore the present invention has the following advantages: 1, raw material is evenly distributed in pond; 2, raw material residence time in pond even, all fermenting raw materials abundances; 3, discharging is easy; 4, while slagging-off, only need, except cinder notch cleaning, not affect the reaction in methane-generating pit, continuous use biogas capable of circulation etc.
As can be seen here, the utility model compared with prior art has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
brief description of the drawings:
Fig. 1 is structural representation of the present utility model;
Wherein, 1 is feeding port, and 2 is top cover, and 3 is discharge port, and 4 is electric motor, and 5 is agitating vane, and 6 is step-down gear, and 7 is material spilling hole, and 8 is helical feed roller.
embodiment:
In order to understand better the utility model, explain in detail embodiment of the present utility model below in conjunction with accompanying drawing.
Embodiment: as shown in Figure 1, a kind of circulating methane-generating pit, comprises the feeding port 1 and the discharge port 3 that are arranged on methane-generating pit top, and described discharge port is provided with seal cover board.Packed top cover 2 is established in the top of methane-generating pit, and the top cover 2 of described methane-generating pit is transparent toughened glass making.Top cover 2 is provided with production well, and the bottom of described methane-generating pit is provided with whipping appts, and the bottom of methane-generating pit is provided with material spilling hole 7; The below of described material spilling hole 7 is provided with helical feed roller 8, and the feeding end of helical feed roller 8 is arranged on the below of discharge port 3; The below of described methane-generating pit is provided with electric motor 4, and electric motor 4 connects step-down gear 6 and drives helical feed roller 8 and whipping appts simultaneously.The whipping appts of described methane-generating pit bottom is the fixing agitating vane 5 being fixed on rotation axis and the rotation axis of methane-generating pit bottom centre.
