Abstract
The utility model discloses a methane tank which comprises a tank body with an inner cavity, and a top cover, wherein the tank body is provided with a feed pipe communicated with the tank body, and a discharge pipe; the top cover is connected with the tank body through a nail with barbs; and the nail and barbs are made of an elastic deformable material. After the top cover is connected with the tank body through the nails with barbs and the nail is driven into the wall of the tank body, the barbs can be insert into the wall to greatly increase the adhesive force, so that the nail can not be easily pulled out so as to increase the fixing power for the top cover, and thus, the nail can not easily become loosened after long-time use, thereby ensuring the sealability of the top cover.
Description
Technical field
The utility model relates to a kind of methane-generating pit, particularly a kind of methane-generating pit of nail fixed roof.
Background technology
When building methane-generating pit, for preventing that biogas from leaking, cause the poisoning and environmental disruption of personnel, methane-generating pit needs complete hermetic seal.Therefore methane-generating pit top cover is one of vitals of methane-generating pit, and whether the structure and layout of methane-generating pit top cover are reasonable, directly have influence on the factor of created gase of methane-generating pit.Traditional methane-generating pit top cover is generally with the larger soil bonding sealing of the seam crossing viscosity of top cover and pond body, or with nail, cover plate is followed closely in pond body top edge.Such top cover and the seam crossing of wall can produce crack after the use of several years, and nail likely can become flexible and make cover plate movable, can make like this resistance to air loss of methane-generating pit reduce, the lost of life.
In sum, be necessary to design a kind of methane-generating pit that makes the seam crossing better tightness of top cover and wall, to address the above problem.
Utility model content
In view of this, the technical problems to be solved in the utility model is to provide a kind of methane-generating pit that makes the seam crossing better tightness of top cover and pond body
The utility model solves the problems of the technologies described above by following technique means:
A kind of methane-generating pit of the present utility model, comprise pond body, top cover with inner chamber, pond body is provided with feed-pipe, the discharge nozzle being communicated with pond body, on described top cover, offers gas collection hole, described gas collection hole connected set tracheae, is connected by being provided with the nail of barb between described top cover and pond body.
Further, described nail and on barb by elastic deformable material, made.
In addition, described nail and on barb can also be made by stainless steel.
Further, described top cover is soft bag.
Further, described soft bag is made by multilayer plastic film.
Further, described feed-pipe connects the faecal passageway in lavatory
The beneficial effects of the utility model: methane-generating pit of the present utility model, comprise pond body, top cover with inner chamber, pond body is provided with feed-pipe, the discharge nozzle being communicated with pond body, between described top cover and pond body, by being provided with the nail of barb, be connected, described top cover is soft bag, and described soft bag is made by multilayer plastic film.To between top cover and pond body, with the nail that is provided with barb, be connected, after nail is hammered into pond body wall, within barb can insert wall, make nail also be not easy to become flexible after long between in use, thus the stopping property of assurance top cover.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the structural representation of methane-generating pit of the present utility model.
Fig. 2 is the structural representation of the nail with barb of the present utility model.
Embodiment
Below with reference to accompanying drawing, the utility model is elaborated, as Fig. 1, shown in 2:
A kind of methane-generating pit of the present utility model, comprise pond body 1, top cover 2 with inner chamber, pond body is provided with feed-pipe 3, the discharge nozzle 4 being communicated with pond body 1, on described top cover 2, offer gas collection hole, described gas collection hole connected set tracheae 5, is connected by being provided with the nail 6 of barb 7 between described top cover 2 and pond body 1.Barb is set on nail, after nail is hammered into, is greatly increasing nail power, make nail be difficult for being pulled out, increased the bed knife to top cover.
For the further improvement of technique scheme, described nail 6 and on barb by elastic deformable material, made.Elastic variable material makes nail barb when hammering into wall can draw close rivet nut, is easy to be tufted into
For the further improvement of technique scheme, described nail 6 and on barb by stainless steel, made.Stainless material makes nail and barb not perishable, durable in use.
As the further improvement of technique scheme, described top cover 2 is soft bag.The top cover cost that soft bag is made is low, lightweight, and is easy to open.
As the further improvement of technique scheme, described soft bag is made by multilayer plastic film.Agricultural plastic film is in daily use, low price, and cost is low.Multilayer film are set makes top cover be difficult for breaking.
As the further improvement of technique scheme, described feed-pipe 4 connects the faecal passageway in lavatory.On the manure pit of methane-generating pit Wei peasant household, transform and make, feed-pipe, discharge nozzle and airway etc. are set on manure pit, build again water pressure house, take full advantage of the existing thing of peasant household, time saving and energy saving, can also make ight soil directly enter methane-generating pit, need not first collect ight soil and drop into again methane-generating pit afterwards, convenient and swift.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
