Abstract
The utility model discloses a methane tank without a movable cover, which comprises a main tank, a water pressure chamber and a charging pipe. A gas conduit is arranged at the top end of the main tank, one end of the charging pipe is arranged at the inner part of the main tank after penetrating through the main tank, the water pressure chamber is communicated with the main tank, and a safety cover is arranged at the upper end of the water pressure chamber. The main tank of the methane tank adopts an up-down hemispherical structure, the structure of the movable cover on top of the present methane tank is cancelled, and the top of the methane tank is a complete sealed whole; when in use, the uncovering and sealing are not needed, so that the methane tank without the movable cover overcomes the problems of gas leakage and inconvenient operation of the present methane tank with the movable cover, thereby providing reliable guarantee for users to realize safe gas utilization. The entire methane tank has the characteristics of simple structure, convenient installation and low cost.
Description
Technical field
The utility model relates to a kind of gas generating unit, and particularly a kind of no removable cover gets methane-generating pit.
Background technology
Biogas be organic substance in anaerobic environment, under the condition of certain temperature, humidity, potential of hydrogen, by the microbial fermentation effect, a kind of inflammable gas of generation.At present biogas is in the existing very long history of the application in vast rural area, and mainly based on people and animals' ight soil, people and animals' ight soil belongs to rich nitrogen raw material to its fermentation raw material, has that fermentation period is short, the fireballing characteristics of aerogenesis.
Traditional methane-generating pit generally adopts brick concrete structure to pile up and forms, and integral body is not removable, and handiness is very poor, adopts the glass fiber reinforced plastic digester gas tank by the suitability for industrialized production market circulation to replace traditional concrete marsh-gas pond but present vast rural area.Present glass fiber reinforced plastic digester gas jar structure mainly comprises main pond, feed-pipe and water pressure house, be provided with removable cover at top, main pond, in use we find the present following problem of methane-generating pit ubiquity: 1, removable cover is as a primary member of pond body, want creative activity lid mouth during construction, and the prefabricated removable cover that matches with lid mouthful diameter, not only need removable cover and decorative cover mould thereof when building the pond, and material the time is taken a lot of work, takes to construction more; 2, all to build removable cover and sealing after feeding intake after having the methane-generating pit pond of removable cover to build up at every turn, removable cover is opened in each discharging again, this is pretty troublesome, and removable cover sealing is bad may cause gas leakage, if when the pond internal gas pressure is excessive even occur towards covering the deflation phenomenon; The methane-generating pit that 3, removable cover is arranged, its removable cover gets opening on the ground, has bigger potential safety hazard.
The utility model content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of removable cover that need not, can not cause biogas to reveal no removable cover methane-generating pit simple in structure, that cost is low, easy for installation.
The technical solution of the utility model is achieved in that a kind of no removable cover methane-generating pit, comprise main pond, water pressure house and feed-pipe, it is characterized in that: be provided with airway on top, main pond, feed-pipe one end passes main pond and places its inside, described water pressure house is communicated with main pond, is provided with relief cover in the water pressure house upper end.
No removable cover methane-generating pit described in the utility model, its described main pond is made up of episphere and lower semisphere and is formed an airtight cavity, airway is arranged on the episphere top, described feed-pipe one end passes episphere and extends in the lower semisphere cavity, water pressure house places the episphere outside, and the opening that has mutual coupling on its underpart and the episphere is interconnected the two.
No removable cover methane-generating pit described in the utility model, its opening end periphery at episphere and lower semisphere are provided with the flange that extends laterally.
No removable cover methane-generating pit described in the utility model, its described water pressure house is spliced by two portions up and down.
No removable cover methane-generating pit described in the utility model, the top of its described water pressure house is cylindric.
No removable cover methane-generating pit described in the utility model, its described feed-pipe is cylindric.
The structure of upper and lower hemispheres is adopted in main pond of the present utility model, cancelled the movable cover structure that existing methane-generating pit uses at Chi Ding, Chi Ding is complete sealing integral body, in use need not to take off lid, also need not to seal, the gas leakage that the methane-generating pit that having overcome has removable cover now exists and the problem of inconvenient operation provide reliable assurance for user security is relieved with gas, and whole apparatus structure is simple, easy for installation, with low cost.
Description of drawings
Fig. 1 is a front view of the present utility model.
Mark among the figure: 1 is water pressure house, and 2 is feed-pipe, and 3 is relief cover, and 4a is an episphere, and 4b is a lower semisphere, and 5 is flange.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As illustrated in fig. 1 and 2, a kind of no removable cover methane-generating pit, comprise main pond, water pressure house 1 and feed-pipe 2, described main pond is made up of episphere 4a and lower semisphere 4b, opening end periphery at episphere 4a and lower semisphere 4b is provided with the flange 5 that extends laterally, being stitched together after the flange contraposition of upper and lower hemispheres forms an airtight cavity, is provided with airway on episphere 4a top.
Described feed-pipe cylindraceous 2 lower ends that are are passed episphere 4a and are extended in the lower semisphere 4b cavity, described water pressure house 1 is spliced and is placed the episphere 4a outside by two portions up and down, the opening that has mutual coupling on its underpart part and the episphere 4a is interconnected the two, be provided with relief cover 3 in water pressure house 1 upper end, the top of described water pressure house 1 is cylindric.
