Embodiment
Embodiment 1: can be clear that from Fig. 1 this is a kind of block form anaerobic ferment devices that is made of concrete fermentation vat 3 and glass reinforced plastic or steel storage cover 1.Described fermentation vat 3 is made of pond tripe 32 and pond neck 31 disposed thereon.Pond tripe 32 is a regular hexahedron container, and the top of pond tripe 3 has 9 opennings 321, and its two faces can be provided with feed and exhaust tube 322 as required.Pond tripe 3 tops be provided with its on each openning 321 corresponding pond neck 31, openning 321 is in the pond neck 31 and with pond neck 31 and communicates, and a storage cover 1 that openning 321 can be covered all is installed in each pond neck 31.Described storage cover 1 is fixedly mounted in the pond neck 31, and storage cover 1 end face is lower than the pond eck, thus the space that formation one is surrounded by storage cover 1 end face and pond neck 31 inwalls above storage cover 1, and this space constitutes water pressure house 4.
From Fig. 1 and the visible present embodiment of Fig. 5 is a suitable block form anaerobic ferment devices that adopts pure nonfluid fermentation raw material, be separated into 9 mutual disconnected cell cavities 323 by dividing plate 324 in the pond tripe 32 of the fermentation vat 3 of block form anaerobic ferment devices, each cell cavity 323 top of pond tripe 32 have an openning 321.Each openning 321 top is equipped with a pond neck 31, and storage cover 1 is installed in the pond neck 31.The characteristics of this structure fermentation vat 3 are that each independent cell cavity 323 is provided with a pond neck 31 of being furnished with storage cover 1, when therefore a cell cavity 323 being reloaded operation, only influence the storage cover gas storage of this cell cavity, and can not influence the storage cover gas storage of other cell cavity.It can realize that each cell cavity of large-scale fermentation unit fed intake and the discharging operation by turns by the different dates.
For making things convenient for the storage cover maintenance on the fermentation unit, also for the replacing of nonfluid fermentation raw materials such as green grass in the pond tripe 32 in the reality use or stalk, storage cover should be opened like a cork.1 of the pond neck 31 of described fermentation vat 3 and storage cover are the releasable assembly structure, as shown in Figure 2, the inwall symmetry of pond neck 31 has L shaped groove 311, the pond neck inwall of present embodiment is provided with symmetric 3 L shaped grooves 311, the cover body of storage cover 1 be provided with pond neck 31 inwalls on L shaped groove 311 corresponding members 11, the storage cover 1 that member 11 is housed can be put into pond neck 31 along groove 311, rotate storage cover 1 then, member 11 on the storage cover 1 is entered in the level trough of L shaped groove 311, last wooden unit or the concrete blocks of inserting in the vertical channel of L shaped groove 311 can make storage cover 1 stuck in pond neck 31.
Because fermentation unit when operation, storage cover 1 will bear bigger to buoyancy, storage cover 1 suffered buoyancy then concentrate on its with member 11 that pond neck 31 is connected on, therefore, storage cover 1 easy deformation.For strengthening the resistance to deformation intensity of storage cover 1, the top of the cover body 13 of storage cover 1 is provided with symmetric stiffening web 12, and member 11 is installed in (as shown in Figure 3) on the stiffening web 12 by fastening piece.
Be transportation or the storage that makes things convenient for storage cover 1, storage cover 1 set member 11 is the movable part of detachable, flexible or rotation.As shown in Figure 3, member 11 is offered bolt on two leg lock of member 11 and is placed the hole for U-shaped folder shape structure, and member 11 can be by being bolted on the stiffening web 12.Member 11 can be unloaded from storage cover 1 during transportation, the storage cover 1 of same size can be nested and stack transportation (as shown in Figure 4).
Storage cover 1 is owing to being immersed in the liquid of pond, so be subjected to atmospheric effect.Be difficult to open as not eliminating the normal atmosphere storage cover.The storage cover 1 that this block form anaerobic ferment devices adopts is the pressure type radome structure that can disappear.As shown in Figure 4, have the ventilating pit 14 of with closure 15 on the cover body 13 of storage cover 1.Ventilating pit 14 is provided with ring flange 16, and sealing cover 15 is installed in by bolt on the ring flange 16 of ventilating pit 14, with ventilating pit 14 sealings.When needs are opened storage cover 1, can open the sealing cover 15 on the storage cover 1 earlier, make air enter storage cover 1 by ventilating pit 14, eliminate the pressure of atmosphere to storage cover 1, can like a cork storage cover be opened.
In order to prevent that rainwater from entering fermentation vat 3 from pond neck 31, pond neck 31 is furnished with the lid 2 that its eck can be hidden.There is black coating on lid 2 surfaces, and black coating helps absorbing the heat of solar radiation, help increasing the pond temperature.In addition, lid 2 can reduce the stink from leakage in the fermentation vat, also has beauty function simultaneously.
Operation logic of the present utility model: fermentation unit to the liquid level of earlier fermented feed liquid being packed into during use floods the storage cover top, when the fermented feed liquid in the pond tripe 32 produces biogas, the biogas bubble enters storage cover 1 by openning 321 under the buoyancy of water effect, the liquid in the storage cover 1 is pressed out to the water pressure house 4 that is surrounded by storage cover 1 end face and pond neck 31 inwalls.When using biogas, the biogas in the storage cover 1 is transported to stove and accessory under the effect of hydraulic pressure.The liquid of water pressure house 4 returns again in the storage cover 1.
Embodiment 2: from Fig. 1 and Fig. 6 as seen, this is the block form anaerobic ferment devices of the pure fluid fermentation raw material of a kind of suitable employing, its basic structure is identical with embodiment 1 with operation logic, difference is: the pond tripe 32 of fermentation vat 3 is separated into 3 mutual disconnected independent cell cavities 323, the top of each cell cavity 323 of pond tripe 32 has 3 opennings 321, be respectively equipped with pond neck 31 on each openning 321, in each pond neck 31 storage cover 1 be installed.
The characteristics of the fermentation vat 3 of this structure are that each independent cell cavity 323 is provided with a plurality of pond necks 31 that are equipped with storage cover 1, whole device is made of a plurality of independently cell cavities 323, each cell cavity 323 is equipped with 322, one of 2 feed and exhaust tubes and is used as feed-pipe, and another root is as discharge nozzle.After the liquid fermentation raw material enters a cell cavity from feed-pipe, can arrive discharge nozzle after experiencing certain fermentation time.
