Abstract
The utility model relates to a novel structure of a household methane generating tank, which comprises a fermentation tank (1), a methane nozzle (4), a residue discharging pipe (5), a fertilizer storage tank (6) and a solar collection cover (7), wherein a material inlet chamber (2) is arranged on the upper part of the fermentation tank (1) and communicated with the fermentation tank (1) via a material inlet pipe (3). The utility model is mainly characterized in that on the basis of the traditional water pressure type methane tank, an acidification tank, a water pressure chamber and a material inlet opening are combined into the material inlet chamber (2); the utility model has the functions of the acidification tank, the water pressure chamber and the material inlet opening simultaneously, the material inlet chamber (2) has the function of desilting, and silt in materials can be avoided entering a main tank. Owing to the structure, the methane tank has the advantages of complete function, simpler structure and convenient construction.
Description
Technical field:
The utility model relates to a kind of structure of domestic methane tank.
Background technology:
China's domestic methane tank is mostly taked the hydraulic type structure.As list meander cloth, prefabricated reinforced concrete assembling, round shape, elliposoidal of national domestic methane tank standard collective drawings (GB/T4570-2002) etc. in.The top of the fermentation vat of tradition hydraulic type biomass pool is provided with opening for feed and water pressure house, in addition according to more general strong inverse flow methane-generating pit and the two-step fermentation self-circulation solar temperature-raising marsh pool in addition of the theoretical application at home of substep fermentation, the two kinds of pond types in back mainly are to have increased an acidification pool, in the hope of obtaining higher factor of created gase.Traditional water pressure type biomass pool structure is comparatively complicated, makes troubles to construction.
Summary of the invention:
The purpose of this utility model is to provide that a kind of function is more complete, structure is simple more, the convenient domestic methane tank of construction.
For achieving the above object, the technical solution of the utility model is as follows, domestic methane tank is made up of fermentation vat, feed space, feed-pipe, valve, scum pipe, fertilizer storing pool, solar energy heating cover, on the basis of traditional hydraulic type biomass pool, acidification pool, water pressure house, opening for feed merged into a feed space, the function that has acidification pool, water pressure house, opening for feed simultaneously, feed space is located at the top of fermentation vat, and is communicated with fermentation vat by feed-pipe.
The import of feed-pipe is positioned at the bottom of feed space, and the upper edge of described feed-pipe is a little more than the bottom of feed space, and the silt in the fresh feed sinks to the bottom of feed space, and major part can not brought fermentation vat into, and cleaning easily.
A solar energy heating cover is set above feed space, and it is made by plastics film and yoke or bamboo frame, brandreth, can improve the temperature of feed space under room temperature effect, and then improve feed temperature.
The utility model is merged into acidification pool, water pressure house, opening for feed a feed space on the basis of traditional hydraulic biomass pool, it has the function of acidification pool, water pressure house, opening for feed simultaneously, makes the function of methane-generating pit more complete, structure is simple more, construction is convenient.
Description of drawings:
Fig. 1 is a kind of novel texture synoptic diagram of domestic methane tank.
1, fermentation vat 2, feed space 3, feed-pipe 4, valve 5, scum pipe 6, fertilizer storing pool 7, solar energy heating cover
Embodiment:
At first, raw material (people holds ight soil, stalk, green grass, sewage) enters feed space 2 by the mode of pipeline or hand feed, and raw material liquefies in feed space 2, acidifying.Along with the air pressure in the fermentation vat 1 reduces, the liquid level of feed space 2 reduces, and raw material enters fermentation vat 1 by feed-pipe 3.Air pressure in fermentation vat 1 increases, and the part natural pond liquid in the fermentation vat 1 is pushed back feed space 2 and liquefies, the acidifying fresh feed mixes, and can accelerate liquefaction, the acidization of fresh feed, has also played the regulating effect of water pressure house simultaneously.
The volume design of feed space 2 should be slightly larger than traditional water pressure house volume, so that not perishable straw soaks in the long period at feed space, treat to enter fermentation vat 1 fermentation after its effective ingredient liquefaction, the acidifying, its not perishable part just can be pulled out from feed space 2, avoided in fermentation vat 1, forming crust, made straw as real more, the easy row of raw material.Feed space 2 can adopt structures such as round or rectangle.
The upper edge of feed space 2 is a little more than the upper edge of scum pipe, and during deslagging, feed liquid only can be discharged to fertilizer storing pool 6 and can not overflow from feed space 2.
The import of feed-pipe 3 is positioned at the bottom of feed space 2, and the upper edge is a little more than the bottom of feed space 2, and its purpose is that the silt in the fresh feed sinks to the bottom of feed space 2, and major part can not brought fermentation vat into, and cleaning easily.
The top of feed space 2 can be according to user's practical situation, with the interim capping of concrete slab (or plank and other materials), as need stay opening for feed when adopting hand feed, as conditions permit a solar energy heating cover 7 can be set above feed space, it is made by plastics film and yoke or bamboo frame, brandreth, under room temperature effect, can improve the temperature of feed space, and then improve feed temperature.
Claims (3)
1. the novel texture of a domestic methane tank, it comprises fermentation vat (1), valve (4), scum pipe (5), fertilizer storing pool (6), it is characterized in that also being provided with a feed space (2) on fermentation vat top, this feed space (2) is communicated with fermentation vat (1) by feed-pipe (3), and described feed space (2) has acidification pool, the water pressure house of traditional hydraulic type biomass pool, the function of opening for feed simultaneously.
2. the novel texture of a kind of domestic methane tank according to claim 1 is characterized in that the import of feed-pipe (3) is positioned at the bottom of feed space (2), and the upper edge of described feed-pipe (3) is a little more than the bottom of feed space (2).
3. the novel texture of a kind of domestic methane tank according to claim 1 is characterized in that in feed space (2) top a solar energy heating cover (7) being set, and it is made by plastics film and yoke or bamboo frame, brandreth.
