Description

Automatically help and prolong the input and output material methane-generating pit

The utility model relates to a kind of helping automatically and prolongs the input and output material methane-generating pit, belongs to the methane-generating pit that human and animal excreta and stalk raw materials form methane at the anaerobic state bottom fermentation.

Original old-fashioned methane-generating pit is made up of five major portions such as main pond, opening for feed, discharge port, top cover, venting holes.This pond is based on coarse fodder, charging and discharging all be disposable from the top cover mouth into and out of, its feed inlet and outlet all falls short of the reality, and only plays the effect of hydraulic pressure lifting.Because raw material is single, so this pond factor of created gase is low, to reload all very bothersome at every turn, produce with supplydemand relationship when opening top cover and just be interrupted, 1 year can only input and output material once, need tens of man-hours, and the aerogenesis peak period only has three months.General four-player family will guarantee the normal supply of gas consumption, wants similar three ponds networking to realize at least, and just must throw the worker just can finish the input and output material operation more than 30 in 1 year; Meander cloth methane-generating pit is made up of main pond, charging pond, material-output tank, top cover, several parts of venting hole.But possesses establishment pattern (be pigsty, lavatory, methane-generating pit etc. three-in-one or four to five in one).Fine fodder can only be used in this pond, builds the necessary combination accessory in pond, and raw material sources are limited, and gas production rate is also just limited, only adapts to large aquaculture family in the past, and plant or public lavatory are set up, and most material stocks crust and can not change out in the pond, form long-term material stock.Material stock is many more, and gas production rate is relatively just low more, and use will produce at interval, still can not guarantee the normal supply of gas production rate.At least wanted clear pond once in 1 year, 1 year input and output material and clear pond will be spent more than ten man-hour at least, and produce with supplydemand relationship during clear pond and also just be interrupted.

The purpose of this utility model is to overcome the deficiency that existing methane-generating pit exists, provide a kind of helping automatically to prolong the input and output material methane-generating pit, the thick fine fodder list of this methane-generating pit is used or is mixed with all can, raw material sources are extensive, and input and output material all is successional, do not have fixedly material stock in the pond, do not exist to produce to use and be interrupted, this pond can be satisfied four-player family life gas consumption for a long time, and three to four of annual input and output material recruitments just needed clear pond once in general 20 years.Fine and smooth settling is only arranged at the bottom, pond, carries out operation under the liquid with special tool or submersible pump, does not need draining to salvage, and influence is produced and used supplydemand relationship anything but, can help and prolong the regular supply of continuous assurance gas consumption.

Above-mentioned purpose is achieved in that to help automatically prolongs the input and output material methane-generating pit, comprise main pond, charging pond, material-output tank, hydrolock top cover assembly, venting hole, between charging pond and main pond, increase a conversion pool, conversion pool and charging pond bottom communicates, and bottom, charging pond is to the conversion pool bottom angled, and the top is that the tilting curve is uncovered, this top, uncovered and main pond communicates, the charging pond communicates with heavy filter tank, and there is a depression pitting in heavy filter tank near charging Chi Chu, and foreign material such as heavy filter sand, stone, soil are played in this hole.Bottom, main pond is to the material-output tank bottom angled, and obliquity is≤25 °, and communicates with the material-output tank bottom.

This helping automatically prolonged the input and output material methane-generating pit, is skillfully constructed, and novel structure can be according to vacant lot situation construction behind the house before the peasant household room, and dividing has convection type and return-flow type.Raw material falls two liters by two in the pond, just finished each part material fermentation gas process.And can not crust in top, main pond, and fine and smooth settling is only arranged at the bottom of the pond, but therefore life-time service does not need clear pond.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail

Fig. 1 helps the structural representation that prolongs the input and output material methane-generating pit automatically for convection type

Fig. 2 helps the structural representation that prolongs the input and output material methane-generating pit automatically for return-flow type

Automatically help and prolong the input and output material methane-generating pit, comprise main pond 3, charging pond 2, material-output tank 6, hydrolock top cover assembly 4, venting hole 5, increase a conversion pool 8 in

charging pond

2 and 3 in main pond, conversion pool 8 communicates with 2 bottoms, charging pond, and 2 bottoms, charging pond are to conversion pool 8 bottom angled, conversion pool 8 tops are that the tilting curve is uncovered, these 3 tops, uncovered and main pond communicate, charging pond 2 communicates with heavy filter tank 1, there is a depression pitting in heavy filter tank 1 near charging Chi2Chu, and flashboard 7 is equipped with in

heavy filter tank

1 and 2 in charging pond, and 3 bottoms, main pond are to material-output tank 6 bottom angled, obliquity is≤25 °, and communicates with material-output tank 6 bottoms.Major parts is that prefabricated component or metallic substance are made, and is bonding or integrally welded with sand-cement slurry.

Place for the place broad, can build up convection type helps automatically and prolongs input and output material methane-generating pit (as Fig. 1), input and

output material pond

2,6 is divided into 3 both sides, main pond, when reinforced first, can be directly add from hydrolock top cover assembly 4, with bacterial classification with cut up with a hay cutter into coarse fodder about 5cm with chopper and pour in the main pond and add entry, fine fodder and liquid enter charging pond 2 by heavy filter tank 1, because there is a small rut in heavy filter tank 1 near charging Chi Chu, fine fodder by the time impurity just be deposited in the pitting.After feed liquid enters charging pond 2, because of charging pond bottom to conversion pool 8 bottom angled, feed liquid just enters in the conversion pool 8 naturally.Feed liquid is fermented in conversion pool and under buoyancy, and feed liquid enters the upper strata in main pond from conversion pool 8 top tilting curve open-mouths, and (also advance virgin material through standing the charging pond, follow-up charging is transition primary fermentation process in the charging pond also.Generally can not exist raw material to influence aerogenesis purity in the main pond), successively increase like this, and carry out fermentation gas.Raw material is decomposed gradually and is discharged in the biogas in gas generation process, the certain moisture content of inspiration little by little again, proportion with regard to relative increase some, add the follow-up feed liquid upper strata, main pond of going forward side by side, along with the increase gradually of quantity, pressure increases gradually, under the promotion of drop duty pressure cooperates, raw material just progressively has been pressed onto bottom, main pond, in aerogenesis and the process with gas, hydraulic pressure is gentle to be pressed under the effect of two way alternate lifting, adds upper bottom portion to material-output tank 6 bottom angled, the old material stock of bottom, main pond has just progressively entered the material-output tank bottom, but its proportion is still less than water, and under the liquid buoyancy effect, old material is again gradually toward come-up then, continuous increase along with follow-up raw material quantity, add that old material has contacted foreign gas once more, hold in the palm water again gradually, proportion alleviates relatively, buoyancy increases relatively, and old material just progressively is raised to material-output tank top.Go round and begin again like this, go production into a streamline, progressively finish the gas generation process of each part material, gas consumption is helped prolong constantly and supplied with.Time has been grown, and can be silted up passage by fine and smooth settling in order to prevent 2,6 bottoms, input and output material pond, and available special instrument is removed.Each part material falls two liters by two in entering methane-generating pit, just finished its production process.Feed liquid is in lifting process, and liquid level is in fluctuation status in the main pond, and the feed liquid in the conversion pool 8 enters in the main pond continuously, so main pond liquid level just incrustive situation can not occur, thereby also just can not influence gas production rate.Flashboard 7 is used to control feed liquid and enters in the methane-generating pit.

For less place, place, then can use return-flow type to help automatically and prolong the input and output material methane-generating pit, its compact construction, effect and principle are consistent.
