Abstract
The utility model belongs to a power supply device, particularly a methane tank used in families in rural districts. The high-efficient and convenient methane tank of the utility model is composed of a feed pipe, an integrally closed structural form main tank body and a discharging tank, wherein a gas guiding pipe is arranged on the top of the main tank body. The utility model is characterized in that the main tank body is connected with the discharging tank by an arch-shaped last hole, and the discharging tank is in a cylindrical structure. The utility model can improve the sealing performance and the gas generating rate of the methane tank, can lead materials inlet and outlet to be convenient, can increase kinds of fermentation raw materials, can have the advantages of labor saving, time saving and material saving, and simultaneously can be favorable for matching construction.
Description
Technical field
The utility model belongs to energy source device, is specifically related to a kind of methane-generating pit for farm household.
Background technology
Biogas is eco-energy, for the protection environment, keeps the eubiosis, and the living condition of improving the peasant has played certain effect, has vast potential for future development.The domestic methane tank of promoting is to be provided with skylight opening at main tank body gas dome top mostly now, and skylight opening adopts the sealing of water seal method, opens in the time of need reloading greatly.The methane-generating pit of this structure, not only difficulty of construction is big, and because skylight opening easily produces the slit with the pond body when engaging, if situations such as cracking appear in water seal mouth lack of water easily, thereby produces gas leak phenomenon, forms the gas of jogging, and makes the tolerance deficiency.The methane-generating pit of this structure is unfavorable for building pigsty on main tank body top simultaneously, makes troubles to auxiliary construction.In addition, existing methane-generating pit exists the feed-pipe bore too small mostly, and placement location and angle are unreasonable, and material-output tank mostly is bottleneck structure, has limited the discharging of residue, makes input and output material become difficult.Existing biomass pool built from glass fiber reinforced plastic, complex structure, the cost height is not suitable for popularizing in the rural area.The Chinese patent publication number is CN2552920Y, open day is on May 28th, 2003, name is called the modified version methane-generating pit, a kind of methane-generating pit is disclosed, though it has cancelled skylight opening on main tank body, main tank body also is a full-closed structure, and it is being provided with side door and is provided with the rank of organizing a performance on the material-output tank road on the main tank body, construction is got up difficult, can not realize the body once shaped of whole pond.Simultaneously, it needs water filling to realize sealing after discharging is finished, and uses inconvenience.
Summary of the invention
It is poor that the utility model has solved existing methane-generating pit overall tightness, the input and output material difficulty, and the technical problem that difficulty of construction is big provides a kind of simple in structure, good airproof performance, input and output material is convenient, is easy to construct and factor of created gase is high efficiently makes things convenient for methane-generating pit.
The purpose of this utility model is achieved in that a kind of methane-generating pit that efficiently makes things convenient for, form by feed-pipe, integrally closed structural formula main tank body, material-output tank, the main tank body top is provided with airway, adopts arched last tunnel to link to each other between main tank body and the material-output tank, and material-output tank is columnar structured.Can make input and output material convenient like this, can utilize high-power pump to realize liquid circulation simultaneously.
The connection angle of feed-pipe of the present utility model and main tank body is 45 °, and the discharge port place of material-output tank is provided with removable cover.
The beneficial effects of the utility model are: improved the sealing property of methane-generating pit, improved factor of created gase, made input and output material more convenient, increased the kind of fermentation raw material.Can save the construction starting material, reduce construction intensity, strengthen the firmness of whole pond body, help carrying out auxiliary construction simultaneously.

Embodiment
The methane-generating pit that efficiently makes things convenient for of the present utility model includes feed-pipe 1, integrally closed structural formula main tank body 2, material-output tank 3, and main tank body 2 is provided with airway 7, links to each other by arched last tunnel 6 between main tank body 2 and the material-output tank 3, and material-output tank 3 is columnar structured.Feed-pipe 1 is 45 ° with the connection angle of main tank body 2, and material-output tank 3 is provided with discharge port 9, and discharge port 9 is provided with removable cover 10.The span scope of arched last tunnel 6 is 55-120cm, and altitude range is 80-200cm, adopts arched last tunnel 6 can make whole pond body realize integrated casting, saving of labor, material-saving, saves time, and can make discharging convenient.Feed-pipe 1 adopts the heavy caliber pipe, its diameter dimension scope is 27-60cm, and be 45 with main tank body 2 and be connected, the diameter range of material-output tank 3 cylinders is 1-1.8m, so not only make input and output material convenient, also can enlarge the kind that raw material uses, both can use the easy molten raw material of ight soil class, also can use all kinds of straws etc., can utilize high-power pump to realize liquid circulation simultaneously.Main tank body 2 adopts integrally closed structure, can improve the stopping property and the heat retaining property of methane-generating pit, thereby improves factor of created gase, helps auxiliary construction simultaneously.During construction, lay one deck plastic film between whole biomass pool body and soil layer can play antiseepage, insulation, isolated effect, prevents that effectively concrete basin is destroyed.
During use, fermentation raw material is sent into main tank body 2 from feed-pipe 1, the sweathouse 4 of main tank body 2 makes the biogas of generation enter between the air storage of main tank body 25 by anaerobically fermenting after, by and water pressure house 8 between pressure reduction make gas enter gas pipe line to be utilized from airway 7.Fermentation residue (natural pond liquid, natural pond slag) then enters material-output tank 3 by arched last tunnel 6, is extracted utilization by discharge port 9.
