Description
Technical field
The present invention relates to a kind of ecological environment-friendly type methane-generating pit.
Background technology
Biogas：Be organic substance in anaerobic environment, under conditions of certain temperature, humidity, acid-base value, pass through micro- life
Thing fermentation, a kind of fuel gas of generation.
Present agriculture leading ecological integrated agricultural, the integration such as livestock, vegetables, planting is cultivated, and by domestic animal
The excrement of poultry is applied fertilizer or for fermenting, and is produced biogas, the fuel of cheap price and excellent quality is provided for rural area, and solve a large amount of mucks
The problem of can not handling in time, environmental protection, health.
Existing methane-generating pit is not provided with efficiently stirring facility during the fermentation, causes fermenting speed slow, fermentation efficiency
Low, fermentation time is long, and fermentation is incomplete；Secondly, existing methane-generating pit does not flow back effectively facility, causes what is fermented
The material that also presence can ferment in bed material, and the blockage problem of backflow is also required to further consideration, prevents blocking from causing
Backflow failure, because the tunning in methane-generating pit is mostly thick, and containing more polymictic compound, then reflux course is only
Strange can often there is the problem of blocking.
In addition, existing methane-generating pit is in the winter time during use, often because in soil temperature reduction, cause to ferment
Temperature is reduced in journey, is unfavorable for being normally carried out for fermentation, can also be interrupted the supply of biogas, although having in the prior art to insulation knot
The setting of structure, but also there is the problem of temperature can be reduced in actual use in the structure, mainly methane-generating pit is typically built
It is located under bottom surface, the moisture vapor in such soil will slowly penetrate into bottom of pond or Chibi, also result in over time
Temperature drop in methane-generating pit, even if there is Insulation to solve the problem of temperature is reduced for a long time.
The content of the invention
For above-mentioned problem, the present invention is intended to provide a kind of ecological environment-friendly type methane-generating pit, the methane-generating pit is not only solved
Existing fermentation efficiency of having determined is low, incomplete problem of fermenting, and the mesh of circulating fermentation can be reached by way of backflow
, make fermentation more thorough, and it is unobstructed to flow back, the problem of being blocked in the absence of backflow, while also solving warm in winter methane-generating pit
Caused by degree declines the problem of fermentation interruption, biogas supply discontinuity.
To achieve these goals, the technical solution adopted in the present invention is as follows：
A kind of ecological environment-friendly type methane-generating pit, the methane-generating pit includes air storage chamber, fermenting cellar and bed material room successively from top to bottom, described
Feed pipe is provided with methane-generating pit, outside is provided with water pressure chamber, and the water pressure chamber side is provided with manure storage pond, the connection of manure storage pond side
Material pond is taken out in setting, and the methane-generating pit is made up of three-decker, and outermost layer is heat-insulation layer, and centre is vacuum layer, and innermost layer is heating
Layer, the feed pipe and described take out are additionally provided with return duct between material pond, and pusher is set in the return duct, described to take out material pond
Set between the bed material room and take out material passage, vertical rotating rabbling mechanism is set in the fermenting cellar.
Preferably, the zone of heating inwall lays heating tube.
Preferably, the vertical rotating rabbling mechanism includes stirring motor, agitating shaft and stirrer gear.
Preferably, being set on the agitating shaft at least one described stirrer gear, the front and back sides of the stirrer gear
Falculate briar tooth is respectively and fixedly provided with, and hook part is provided with the end of each briar tooth.
Preferably, the pusher includes charging ram and pusher disk, set along its length on the charging ram
Several described pusher disks.
Preferably, each pusher disk is constituted by scraper annulus and ribs, the scraper annulus passes through some
Ribs described in root is fixed on the charging ram.
Preferably, the bottom for taking out material passage sets horn-like material of taking out to be open.
Preferably, described take out provided with material bar is taken out in material passage, material head is taken out in the end for taking out material bar provided with semicircular.
Preferably, setting at least one counterpunch board on the inwall of the fermenting cellar.
The beneficial effects of the invention are as follows：Compared with prior art, of the invention to the improvement is that, the present invention is to stirring first
Mix facility to be improved, drive stirrer gear to realize by stirring motor and stir, while in order to improve the effect of the stirring in whipping process
Really, therefore on stirrer gear briar tooth is set, because fermentation materials are thick, therefore by the shearing force of briar tooth during rotation
Stirring and mixed effect can be improved, and then improves fermentation efficiency；
Secondly, the material that fermentation is completed can be deposited in bottom as bed material, and bed material needs periodically to be handled, but can in bed material
There can be Partial fermentation not complete enough, therefore by setting return duct, make bed material again by charging material charging, carry out circulating fermentation
Purpose, and in order to ensure the unobstructed effect in reflux course, the present invention also sets up pusher, can be protected by pusher
Card reflux course is smoothly completed；
Again, the present invention is in order to solve the problem of low fermentation of winter temperature is interrupted, therefore sets heat-insulation layer, vacuum layer and heating
Layer, the problem of methane-generating pit temperature drop can solve the problem that by the setting of said structure, and then enable the fermentation in methane-generating pit
Continue.
