Description

A kind of methane-generating pit

Technical field: the utility model relates to a kind of methane-generating pit.

Background technology: the methane-generating pit kind is a lot of at present, the monoblock type building block is arranged or build and build the pond, or prefabricated board-like built-up type is built the pond, the common fault of the methane-generating pit of this class formation be gas leakage, leak or aerogenesis not high, even use the air-tightness split type methane-generating pit that builds up of material preferably, also because each minute body component such as the setting of charging and discharging mouth etc. and resistance to air loss mismate mutually, the problem that its gas leakage is leaked still exists.The quality of methane-generating pit sealing property is the most important condition of biogas fermentation aerogenesis, the good biogas so can methane-generating pit normally use and output is many, and the sealing problem of its methane-generating pit is a key point of manually producing biogas.

The utility model content: the purpose of this utility model provides a kind of good airproof performance, and is simple in structure, feed intake, clear up the natural pond slag easily, split type methane-generating pit.

Technical solutions of the utility model comprise

Proving room, cover cap is characterized in that being provided with the water seal groove in described proving room upper end around its perisporium in the gas storage enclosure of proving room upper port, and described gas storage enclosure passes through the detachable cover cap of this water seal groove on proving room.

Be respectively equipped with the charging and discharging mouth with pipe connection on the described proving room, wherein opening for feed is offered the position and is higher than discharge port, and described its other end of pipeline that is connected with the charging and discharging mouth respectively respectively is provided with the water seal groove around its perisporium, and this water seal groove is provided with manhole cover.

Described opening for feed is through Y-tube and be connected with heavy water swan neck.

Described heavy water swan neck is a U type pipe.

Be provided with the water seal groove of upward opening around its cover wall in described gas storage enclosure lower end.

Described proving room, gas storage enclosure and manhole cover form split type drum type respectively; Described water seal groove is located at the charging and discharging mouth of pipe respectively, and on the outer wall of proving room, gas storage enclosure mouth, and the height outer, interior two its outer panels of side plate of formation water seal groove is lower than its interior plate.

The notch horizontal plane of described gas storage enclosure water seal groove is lower than or flushes in the notch horizontal plane of the water seal groove on the proving room; It is 50～80mm apart from proving room floor level face height that described proving room discharge port is offered the position; Constitute at the bottom of the height of outer, interior two its outer panels of side plate of proving room water seal groove in its interior plate 80～100mm, this water seal groove is dark, width is respectively 50～80mm and 150mm.

The outer panel of the outer panel of described gas storage enclosure water seal groove and described proving room water seal groove is connected and fixed with screw or W type spring.

The utility model rationally decomposes each parts of methane-generating pit, is convenient to set up install and the maintenance use, can effectively avoid leaking gas leakage because the combination of its each parts adopts water sealed tank to be sealed and matched; Simultaneously owing to offer the charging and discharging mouth respectively, feed intake and not only convenient but also can prevent to run and emit biogas during deslagging at proving room.But the utility model suitability for industrialized production, it is simple in structure, makes easily, and is with low cost, and the factor of created gase height, and every day, every cubic metre of raw material aerogenesis can reach 0.3-0.45m ³

Description of drawings: accompanying drawing is a kind of example structure synoptic diagram of the utility model.

Embodiment: as shown in the figure, gas storage enclosure 1 and proving room 7 usefulness plastics form split type drum type respectively, set water seal groove is for directly being located at the annular seal-water tank 4 on the proving room upper port outer perimeter wall on the proving room, and the outer panel 3 that constitutes this water sealed tank 4 highly is lower than its interior plate 2 about 90mm, makes the horizontal plane of this water sealed tank 4 be lower than the about 90mm of horizontal plane of proving room 7 upper port; The degree of depth of water sealed tank 4 and width are respectively 60mm and 100mm; The U type annular seal-water tank 11 of the set water seal groove of gas storage enclosure 1 lower port for directly constituting by outside, the last direction crimping of the cover wall of gas storage enclosure 1 itself, gas storage enclosure 1 is placed on the water sealed tank 4 of proving room 7 by these water sealed tank 11 movable guards, and the water sealed tank 11 of gas storage enclosure 1 is positioned on the same horizontal plane with water sealed tank 4 its both notch planes of proving room 7.The discharge port 6 of proving room 7 is located at apart from proving room 7 floor level face 50mm places, and opening for feed 8 is located at the top with respect to discharge port 6; Opening for feed 8 is connected with feed-pipe 13 with the heavy water elbow 10 of U type respectively through threeway 9, discharge port 6 is connected with discharge nozzle 12, set respectively water seal groove is for directly being located at the annular seal-water tank 5 on its pipeline outer wall on charging and discharging

pipe

13,12 mouth of pipe periphery walls, the height outer, interior two its outer panels of side plate that constitutes this water sealed tank 5 is lower than its interior plate, makes the notch horizontal plane of water sealed tank 5 be lower than the horizontal plane of its corresponding separately charging and discharging pipeline mouth of pipe; Mould notes drum type manhole cover 14 and pass through water sealed tank 5 cover caps on charging and discharging
