Abstract

The utility model provides a methane generating device, which comprises a flexible fermentation tank with a material inlet port, a material discharging port and a gas guiding port. The utility model is characterized in that a material cleaning port is arranged on the wall of the fermentation tank and used for people going in and out, and an openable sealing element is disposed at the material cleaning port. The people can freely go in and out of the fermentation tank. The utility model can be used for generating methane in large and industrialized scale; and has the advantages of no influence by foundation settlement, good sealability, high safety, and convenient installation.

Description

Biogas generating device

Technical field:

The utility model relates to a kind of methane-generating pit, and especially to prepare the generating unit of biogas relevant with organism such as people, animal, poultry manure, straw being carried out anaerobically fermenting.

Background technology:

At present, the many rigid pond bodies of existing methane-generating pit, ubiquity cost height, defective such as stopping property is poor, production cycle is long with the thermoset material structure.And the fermentation unit of existing soft plastic material, can't enter in the fermentation unit during clear people from pond, and the natural pond slag heat retaining property in winter that can not clear up long-term alluvial is poor.

The utility model content:

The purpose of this utility model is to overcome the deficiency of prior art, give full play to the advantage of solid methane pond and soft methane tank, provide a kind of settlement of foundation that is not subjected to influence, good airproof performance, security be good, easy for installation, can realize the people pass in and out fermentation vat can be on a large scale, the biogas generating device produced of industrialization.

Another purpose of the present utility model is for a kind of biogas generating device of good heat preservation performance is provided.

The utility model biogas generating device comprises the flexible fermentation vat of being with opening for feed, discharge port and air guide port, it is characterized in that having on the fermentation vat pool wall for human body into and out of residue-removing opening, but be contained in the opening encapsulation spare at residue-removing opening place.

Above-mentioned fermentation vat residue-removing opening periphery has and pool wall all-in-one-piece residue-removing opening bead, but at least two sealing clamps that the residue-removing opening bead is fixed are arranged in the opening encapsulation spare, the follower bolt that cooperates with sealing clamp, when slag alluvial in natural pond can't run well whole device too much in the pond, follower bolt on the residue-removing opening is laid down, personnel can enter in the fermentation vat from the residue-removing opening of opening, after having cleared up residue-removing opening is patted, residue-removing opening is pushed down from the two sides with pressing plate then, bolt is tightened the sealing that just can realize fermentation vat by the pressure of contact surface.

Above-mentioned fermentation vat pool wall is the sandwich structure of band air chamber, and valve inside is equipped with at pool wall air chamber air inlet/outlet place, high insulating effect.

Above-mentioned fermentation vat is made up of flexible inner bag and the flexible outer bag that is sleeved on the flexible inner bag, and tie point and formation air chamber are arranged between inside and outside bag.

Withhold on above-mentioned flexible fermentation vat top, inserts the steady arm in withholding, and will withhold with steady arm just to string and can prop fermentation vat, and structure shape such as tent provide an operating space for clear material personnel, greatly facilitate operation.

But the utility model can be opened and the sealing and fermenting pond easily by opening encapsulation spare, makes things convenient for personnel to operate in the pond, helps the maintaining of this fermentation unit.Adopt air chamber, improved the heat-insulating property of methane-generating pit, the aerogenesis time in winter is improved greatly.

The utility model good airproof performance, security is good, not influenced by settlement of foundation, and is easy for installation, can realize extensive, industrialization production biogas.

Fig. 4 is put figure for the I portion among Fig. 1.

Embodiment:

Referring to Fig. 1～Fig. 4, flexible fermentation vat 23 is made up of outer fermentation bag 1, internal layer fermentation bag 2 that the heat seal of PVC (polyvinyl chloride) sheet stock forms, between inside and outside bag some heat seal points are arranged, not only interconnected but also formed air chamber 24 between two bags, the valve inside 3 that air is gone up the inlet mouth place by outer bag enters between two bags.Feed-pipe 11 is equipped with at fermentation vat underfeed mouth place, the discharge port place is equipped with discharge port cock 8, discharge nozzle 10, stretch into and take out glassware 9 in the discharge nozzle 10, branch kettle 15, desulfurizing device 16, force (forcing) pump 17, the relief valve 18 that be equipped with airway 14, be connected with airway at air guide port place, top are connected with kitchen range 19 by pipeline.The fermentation vat top has a plurality ofly withholds 13, is through the steady arm of withholding 12.Fermentation vat is divided between sweathouse 20, gas storage 21.Have and pool wall all-in-one-piece residue-removing opening bead 25 at fermentation vat residue-removing opening 5 peripheries, but two sealing clamps 6 in the opening encapsulation spare 26 compress the sealing at usefulness follower bolt 4 fastening realization residue-removing opening places from the two sides with the residue-removing opening bead.Opening encapsulation spare also can adopt clip or other structure.

This biogas generating device will connect feed-pipe 11 and discharge nozzle 10 and airway 14 earlier when operation, marsh gas fermentation pool is put into excavated good Chi Jizhong then, and each pipe is fixed.Fermentation raw material enters sweathouse 20 by feed-pipe 11, after feed liquid covers 11 mouthfuls of feed-pipes, 21 just form an enclosed space between gas storage, the biogas that fermentation produces will be full of between gas storage 21, when pressure reaches certain, natural pond liquid is pressed into external water pressure house by discharge nozzle 11, under the effect of water pressure house biogas is imported airway 14, when insufficient pressure, can start force (forcing) pump 17 with biogas from the airway suction.

When temperature is low, with adding inflator pressurized air is injected the airbag interlayer, this air chamber 24 can play good insulation effect, when fermentation unit uses this function can improve factor of created gase greatly in winter when temperature is low.

When the natural pond slag deposits thicker, need operator to enter clear pond in the pond, as long as the follower bolt on the sealing clamp 64 is backed out, take off sealing clamp 6, just can open residue-removing opening 5, enter desilting in the pond, after clear material finishes sealing clamp 6 usefulness follower bolts 4 are tightened, just can effectively seal, the discharge port cock can be outwarded winding when not being very serious, allowing alluvial discharge when alluvial.The available at ordinary times glassware 9 of taking out is extracted sediment out.

When the needs operator enter in the pond clear pond, with a vaulting pole 12 with top withhold string together, fixedly steady arm 12 just can be propped up soft methane tank then, handled easily.
