Abstract

The utility model discloses a methane tank, comprising an upper tank, a lower tank and a top cover. Wherein the upper tank and the lower tank are connected into an integral, the top cover is arranged at the top of the upper tank and is cast to an integral with the upper tank so as to seal the methane tank. A reaction chamber is arranged at the middle lower part of the upper tank, water pressure compartments are arranged at the upper part of the upper tank, the water pressure compartments and the reaction chamber are cast into an integral. A material inlet tube is connected between one water pressure compartment and the reaction chamber, a material outlet is connected between another water pressure compartment and the reaction chamber, the top cover is provided with a gas outlet, the gas outlet is connected with the reaction through tube. As the water pressure compartments and the reaction chamber are cast integrally in the utility model, the methane tank has the advantages that to generate the cracks is uneasy, gas and liquid leakage, simultaneously can realize the industrialization, standardization and batch production, moreover the utility model has simple and convenient transportation, short operation cycle and low cost, and can widely be applicable for rural household and agricultural greenhouse production.

Description

The biogas jar

Technical field

The utility model relates to a kind of biogas jar, relates in particular to a kind of biogas jar that utilizes anaerobically fermenting to produce biogas.

Background technology

At present, a lot of places utilize anaerobic degradation straw and people and animals' ight soil to produce biogas, this has promptly made things convenient for life to save the energy again, but the pond that is used to produce biogas is to utilize local method mostly, directly dig pit underground, be built into a methane-generating pit then, react generation biogas at methane-generating pit, must empty overhaul in per like this 2 to 3 years, cause very big man power and material's waste, and existing water pressure house and reaction chamber be isolating, this just is easy to produce the crack, cause the deflation leakage simultaneously, methane-generating pit is scrapped.In addition, because winter temperature is lower, and methane-generating pit just can not produce biogas, this has brought a lot of inconvenience to life in the north.

Summary of the invention

In order to solve the problem of above-mentioned existence, the purpose of this utility model provides the leakage that do not become flat of a kind of difficult generation crack, at all seasons all can the balanced biogas jar that produces biogas.

The technical solution of the utility model is to realize like this, a kind of biogas jar comprises jar, following jar and top cover, wherein goes up jar and connects as one with following jar, last jar top is provided with top cover, and jar be cast into one with last, and making the sealing of biogas jar, the middle and lower part of last jar is provided with reaction chamber, last jar top is provided with water pressure house, water pressure house and reaction chamber are cast into one, are connected with feed-pipe between water pressure house and the reaction chamber, are connected with discharge port between another water pressure house and the reaction chamber; Top cover is provided with an air outlet, and the air outlet is connected with reaction chamber by pipeline.

Last jar with following jar be linked to be by bolt and be one.

Described biogas jar forms by precast concrete is prefabricated.

Middle and lower part at described reaction chamber is provided with peeler.

Described peeler is to be supported on the reaction chamber wall and middle many spreaders that combine together.

Described spreader is two.

Compared with prior art, the beneficial effects of the utility model are:

1, all structures, especially water pressure house and the reaction chamber in the utility model biogas jar is integral cast, is not easy to produce the crack and the deflation leakage.

2, can realize batch production, stdn, mass production.

3, the utility model biogas jar reaches 30 years work-ing life, the production and transport simple installation, and the duration is short, and expense is low, can be widely used in rural households' life and agricultural greenhouse production.

4, owing to can make jar interior temperature comparatively constant, be more suitable for China's wide geographic area and use by ground temperature.For the lower north of temperature, use this biogas jar also can produce biogas in the winter time.

Fig. 1 is the utility model structure partial sectional view.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail, but not as to qualification of the present utility model.

Biogas jar of the present utility model is mainly used in anaerobic degradation straw and people and animals' ight soil, as shown in Figure 1, a kind of precast concrete biogas jar, comprise jar 1, following jar 2 and top cover 9, they are connected as one by bolt, organic raw material and water enter reaction chamber 4 from the opening for feed 6 of water pressure house 5 bottoms of biogas tank top, collect from last jar 1 air outlet 8 through the biogas that the anaerobism fermentation produces, the biogas that when not using biogas, produces in the reaction chamber 4 constantly the natural pond liquid in the reaction chamber 4 by opening for feed 6, discharge port 7 heads into water pressure house 5, when using biogas, along with biogas reduces, natural pond liquid again by water pressure house 5 through discharge port 7 opening for feeds sucting reaction chambers 46, go round and begin again.When having the scum silica frost hull shape to become in the biogas jar, along with natural pond liquid fluctuates, peeler 3 squeezes the scum silica frost shell broken, overflows liquid level in order to biogas.Natural pond slag in the biogas jar and natural pond liquid are by pump or manually from discharge port 7 extractions.

Claims

1, biogas jar, comprise jar, following jar and top cover, it is characterized in that jar connects as one with following jar, last jar top is provided with top cover, and is cast into one with last jar, make the sealing of biogas jar, last jar middle and lower part is provided with reaction chamber, and last jar top is provided with water pressure house, and water pressure house and reaction chamber are cast into one, be connected with feed-pipe between water pressure house and the reaction chamber, be connected with discharge port between another water pressure house and the reaction chamber; Top cover is provided with an air outlet, and the air outlet is connected with reaction chamber by pipeline.

2, biogas jar according to claim 1, it is characterized in that described go up jar with following jar be linked to be by bolt and be one.

3,, it is characterized in that being provided with peeler in the middle and lower part of described reaction chamber according to the described biogas jar of claim 1-2.
