Abstract

The invention discloses an anaerobic automatic gas-agitating generator, which belongs to an ancillary facility of an anaerobic container (biogas generating pit). The generator comprises a gas hood (1), a gas chamber (2), a U-shaped tube (3), and supporting pull rods (4), wherein the anaerobic automatic gas-agitating generator is movably connected to the center of the lower half part of a fermentation room by the four supporting pull rods (4); with the gas pressure increasing in the gas hood and breaking through a water seal of the U-shaped tube to exhaust gas, the material liquid on the upper part of the fermentation room is stirred and a shell is broken; and at the same time the gas is exhausted to reduce the gas pressure in the gas hood, raise the liquid level and pull the material liquid surrounding the bottom and the generator to get in the fermentation room. Thus the repeated operations resolve the problems that the material liquid in the fermentation room is incrusted and the lower part of the fermentation room is blocked by sediments to result in the disuse or the abandonment of the biogas generating pit; besides, the gas production is greatly improved.

Description

Anaerobic automatic air agitation generators

Technical field

The present invention relates to a kind of anaerobic automatic air agitation generators, belong to the support equipment of anaerobism container (methane-generating pit).

Background technology

At present, China's methane-generating pit for farm household ubiquity fermented feed liquid come-up crust and bottom sediment stir difficult problem.Scientific research that has and popularizing department adopted ways such as artificial mechanism stirring, air pump stirring, inner mounting bracket, bamboo cage broken shell all undesirable.Having a strong impact on the raising of biogas benefit, is the key technical problem that solution is badly in need of in current Chinese countryside biogas great development period.

Summary of the invention

The objective of the invention is to stop up, stir difficult problem, a kind of anaerobic automatic air agitation generators is provided, be used to overcome the above problems for the fermented feed liquid come-up crust, the bottom sediment that solve existing methane-generating pit existence.

Above-mentioned purpose is achieved in that anaerobic automatic air agitation generators, comprises gas hood, air chamber, U type pipe, pull bar.Gas hood is round shape, square tube shape or other and the corresponding shape body of sweathouse, and it is movably connected in sweathouse Lower Half central authorities by four tie-struts, and a port of U type pipe is fixedlyed connected with the gas hood top open part, and another port is fixedlyed connected with air chamber wall.The air chamber flange face is connected with gas hood top open part bolt or welds, the sealing of recycle silicon clay.The mode of connection that the port of U type pipe and the wall welding of gas hood open top, another port and air chamber, clamping or other and air chamber shape adapt.After the sweathouse charging feedstock starts, the fermentation of gas hood coverage rate lower feed produces gas and enters in gas hood or the air chamber, the gaseous tension that produces enters U type pipe by air chamber, increase along with the gas hood internal gas pressure, when pressure reached U type pipe bottom, it just broke through U type pipe water seal exhaust, rushes at sweathouse top, so repeatedly, produce stirring, broken shell effect.Having solved for a long time, the methane-generating pit sweathouse stirs difficult, the difficult problem of broken shell.

Anaerobic automatic air agitation generators adopts the manufacturing of polypropylene modification plastics, nontoxicity, acid and alkali-resistance, and work-ing life is more than 20 years.When building the pond construction it is installed in the sweathouse lower central, does not need any management for a long time.When breaking through U type pipe water seal exhaust along with the increase of gas hood internal gas pressure, play the effect of stirring top feed liquid and broken shell, exhaust simultaneously reduces gas hood internal gas pressure liquid level and rises, feed liquid enters around pulling bottom and the producer again, just solved sweathouse feed liquid crust so repeatedly, the bottom sediment stops up, the problem that causes methane-generating pit to scrap, and improve gas production rate greatly.

Embodiment

In conjunction with the accompanying drawings one embodiment of the present of invention are described in further detail

Anaerobic automatic air agitation generators comprises gas hood 1, air chamber 2, U type pipe 3, tie-strut 4.Gas hood 1 is a round shape, it is movably connected in sweathouse Lower Half central authorities by four tie-struts 4, port of U type pipe 3 and gas hood 1 open top welding, and the wall of another port and air chamber 2 welds, the flange face of air chamber 2 is connected with bolt 5 with gas hood 1 top open part, the sealing of recycle silicon clay.Gas hood 1 can be round shape, or the shape body that adapts of square tube shape, rectangle, cone-shaped or other and sweathouse, is installed in the type container of difform anaerobically fermenting pond, all can produce automatic gas mixing and mix effect.When using in large and medium-sized methane-generating pit (jar), gas hood 1 is an one-piece construction, as shown in Figure 1.When in the small-sized methane pond, using, for the monolithic manufacturing combines, (because skylight, small-sized pond is young, one-piece construction is difficult to pack into and take out) as shown in Figure 5.

Claims

1. methane-generating pit anaerobic automatic air agitation generators, comprise gas hood (1), air chamber (2), U type pipe (3), tie-strut (4), it is characterized in that: the shape body that gas hood (1) adapts for round shape or other and sweathouse, it is movably connected in sweathouse Lower Half central authorities by four tie-struts (4), the mode of connection that a port of U type pipe (3) is fixedlyed connected with gas hood (1) open top or other and air chamber shape adapt, the mode of connection that another port is fixedlyed connected with the wall of air chamber (2) or other and air chamber shape adapt, the flange face of air chamber (2) is connected with bolt (5) with gas hood (1) top open part or welds, the sealing of recycle silicon clay.
