Summary of the invention

The purpose of this utility model provides the energy industrialization production of a kind of producer, convenient, the stable integrated type voltage regulation methane-generating pit of biogas pressure of user installation.

In order to realize above-mentioned purpose, the integrated type voltage regulation methane-generating pit that is provided, comprise that the top has the fermentation vat of arch mouth, its constructional feature is to be connected to dome shaped cover and to be connected with material-output tank at the arch mouth periphery position of fermentation vat removable cover, dome shaped cover is arranged in the inner chamber of material-output tank, be connected with down the discharge nozzle that reaches the fermentation vat inner chamber on the end face of dome shaped cover and be connected with the overhanging airway of sidewall that passes material-output tank, be communicated with the biogas pipe that leads to the user on the airway, the upper ends of material-output tank has feeder, the short intubate of once stretching is arranged on the feeder, be socketed with the feed-pipe that reaches fermentation vat inner chamber active coating position under the inner chamber that passes discharge nozzle on this weak point intubate, near fermentation vat, be provided with the voltage stabilizing pond, be communicated with the feed liquid thrust-augmenting nozzle between this voltage stabilizing pond and the material-output tank, above-mentioned fermentation vat, dome shaped cover, material-output tank and feeder all are the glass reinforced plastic bodies.

Above-mentioned feeder can be the plane feeder, and the short intubate on the feeder of plane is communicated with curb in the pigsty of lavatory when mounted, and feeder also can be the charging pond, charging for convenience, and one side is provided with opening for feed in the bottom in charging pond.

Transportation for convenience and installation, fermentation vat is divided into two halfbodies that can seal butt joint, and when four sides of fermentation vat were rectangular parallelepiped and are used in the pigsty of lavatory, these two halfbodies were left halfbody and right halfbody, when fermentation vat was elliposoidal, these two halfbodies were upper semi-body and lower semi-body.

For ecology is utilized natural pond liquid and natural pond slag in the voltage stabilizing pond, use as fertilizer sources, feed, integrated type voltage regulation methane-generating pit provided by the utility model also comprises and the fertile pond of holding of voltage stabilizing pond adjacency, is provided with overflow port on the top of holding fertile pond and voltage stabilizing pond abuts with wall.

Integrated type voltage regulation methane-generating pit provided by the utility model, the straw raw material that crushes is put into the charging pond, raw material in the pigsty of lavatory enters the charging pond through the opening for feed that curb flows on plane feeder or the charging pond, these raw materials enter into the active coating of fermentation vat through feed-pipe, ferment, produce biogas, pressure in the fermentation vat increases, the part feed liquid is pressed in the material-output tank through discharge nozzle, and enter the voltage stabilizing pond through the feed liquid thrust-augmenting nozzle, the biogas that is produced through airway and biogas pipe to the user for biogas.After the feed liquid in the voltage stabilizing pond rose to setting height, feed liquid enters through overflow port held fertile pond.

Because the voltage stabilizing pond is communicated with material-output tank by the feed liquid thrust-augmenting nozzle, material-output tank is communicated with fermentation vat by discharge nozzle, when the pressure in the fermentation vat increases, feed liquid in the fermentation vat flows in the voltage stabilizing pond, when the pressure in the fermentation vat reduces, feed liquid in the voltage stabilizing pond is back in the fermentation vat again, thereby makes the pressure in the fermentation vat keep horizontal fixed.

Integrated type voltage regulation methane-generating pit provided by the utility model, its beneficial effect is: 1, because material-output tank is arranged on the top of fermentation vat arch mouth, the top that the charging pond is arranged on material-output tank, thereby having reduced floor space, the fermentation vat good heat insulation has improved the factor of created gase in winter; 2, fermentation vat, dome shaped cover, material-output tank and charging pond all are the glass reinforced plastic bodies, and manufacturer not only can industrialization production, and transportation in light weight, convenient and intensity height, long service life are installed; 3, adopt the central feeding mode, charging is convenient; 4, dome shaped cover can be opened when discharging, has solved the difficult problem of traditional methane tank use straw raw material discharging difficulty; 5, the setting in voltage stabilizing pond, the pressure-stabilisation of biogas brings convenience for the user uses.
