Description
Technical field
The utility model relates to a kind of biogas production apparatus field, exactly relates to a kind of weighing apparatus and presses methane-generating pit.
Background technology
The application of biogas technology starts from 1875, begin large-scale promotion application in China rural area the seventies in last century, in recent years, the Chinese government has strengthened the supporting dynamics that biogas is built, to end in 2005, China built up the family, rural area with surplus the pond 1,700 ten thousand mouthfuls, a few years from now on, annual also can be with the speed increment more than 3,000,000 mouthfuls, existingly build the needs that pool technology has not satisfied construction speed.China's domestic methane tank fermentation technique is still used the hydraulic type biogas technology in more than 20 year at present, " biogas technology " table 1-17 according to Methane Scientific Research Inst., Ministry of Agriculture's establishment is described, by test, the pressure-balance type methane-generating pit improves 18% than hydraulic type biomass pool factor of created gase; The current methane-generating pit of promoting in China rural area mainly is a brick mix structure, this structure methane tank production cycle 15~20 days, and main difficulty is the making of storage cover, leak rate is more than 5%.Simultaneously,, need site operation, not can manufacture because of sweathouse and storage cover are the one of masonry structure.When sweathouse stops up not aerogenesis, maintenance, big discharging difficulty, personnel go into the pond discharging security incident easily take place.Also have employing that the sweathouse and the storage cover integral body of methane-generating pit are made with materials such as plastic cement, the corrupt substance that produces during fermentation is easy to degenerate sweathouse, and plastic material is easy to aging and hydrolysis, and shortened the work-ing life of methane-generating pit greatly.And safety performance is low, and leakage accident takes place easily.
Summary of the invention
The utility model is intended at above-mentioned the deficiencies in the prior art, the weighing apparatus that provides a kind of and make things convenient for pan feeding, gets material, no potential safety hazard is pressed methane-generating pit, adopt the structure of rubber and plastic storage cover of the present utility model and stable-pressure device, can keep biogas pressure balance in the methane-generating pit, improve biogas output and burning quality.
To achieve the above object of the invention, the utility model has adopted following technical scheme:
A kind of weighing apparatus is pressed methane-generating pit, comprise storage cover, be arranged at escape pipe, sweathouse on the storage cover, be arranged at opening for feed and discharge port on the sweathouse, it is characterized in that: described storage cover is the rubber and plastic storage cover, rubber and plastic storage cover bottom and the sweathouse outer wall is movable is tightly connected, the rubber and plastic storage cover is connected the contact position with the sweathouse external wall of upper portion and is provided with sealing-ring, is provided with stable-pressure device on the outside escape pipe of sweathouse and storage cover.
Described stable-pressure device is a stabilized pressure pump.
Be provided with the rack that is movably connected on sweathouse inwall top between described sweathouse and the rubber and plastic storage cover.
Described rubber and plastic storage cover adopts rubber, the plastic materials system of closing to form, and its top is semisphere, and the bottom is cylindrical.
Principle of work of the present utility model is: during pan feeding, fermentation raw materials such as human and animal excreta are sent into methane-generating pit through opening for feed, after the fermentation, take out through discharge port.When the big discharging of needs, can take off the rubber and plastic storage cover, open rack, the raw material after directly will fermenting from sweathouse takes out; When methane-generating pit began aerogenesis, the rubber and plastic storage cover began to fill, owing to adopt movable sealing to connect, biogas can not leak.Increasing or reducing, corresponding increase of rubber and plastic storage cover or minimizing equal volume, thereby maintenance biogas pressure balance along with biogas.The biogas of output can guarantee biogas incendiary quality after the stabilized pressure pump voltage stabilizing.
Advantage of the present utility model is:
1, because the utility model adopts the rubber and plastic storage cover, along with biogas in the rubber and plastic storage cover reduce can dwindle equal volume automatically, thereby can keep the biogas air pressure balance well, and rubber-plastics material have anti-hydrolysis, ageing-resistant, acid and alkali-resistance, good airproof performance, performance that intensity is high.
2, be connected with sweathouse is movable owing to the rubber and plastic storage cover, when needing big discharging, can conveniently take off rubber and plastic storage cover pan feeding, get material, simultaneously, be convenient to change sealing-ring and sweathouse is keeped in repair and overhauls, installation is convenient, when fermentation raw material crust in the pond or not during aerogenesis, can take off storage cover quickly and easily and stir, and can produce storage cover in batches.Connect the contact position sealing-ring is set, prevent that biogas is revealed from the junction in the rubber and plastic storage cover.
3, because the utility model is provided with rack, prevent to fall into sweathouse when the rubber and plastic storage cover is in negative pressure, prevent that escape pipe from stopping up and damaging the rubber and plastic storage cover.
4, because the utility model is provided with stabilized pressure pump on escape pipe, the pressure that can fully guarantee the used biogas of user is balance more, and burning quality is further enhanced.
5, novel, simple in structure, the construction period weak point of the utility model, good seal performance, long service life have market application foreground widely.
