Abstract
The utility model discloses a biogas digester with a movable top cover. The biogas digester comprises a tank body and the top cover, wherein a feeding pipe and a discharging pipe are arranged on the tank body; a sliding device is arranged on the inner wall of the side face of the tank body, and the top cover is in sliding connection with the sliding device; the sliding device comprises a chute which is vertically arranged on the inner wall and a lifting block which is capable of sliding along the chute; maximum upward displacement of the lifting block is limited through a stop block at the upper end of the inner wall of the tank body; the top cover is a soft bag; and the soft bag is made from multiple layers of plastic thin films. The top cover of the biogas digester disclosed by the utility model is made from multiple thin films and the top cover is in sealing connection with the sliding device which is capable of moving up and down, so that the top cover can move up and down depending on different methane contents in the tank; therefore, the movable top cover is good in sealing performance, simple in structure, low in manufacturing cost, light in weight and wide in adaptability.
Description
Technical field
The utility model relates to a kind of methane-generating pit, particularly a kind of removable top cover methane-generating pit.
Background technology
Biogas is that organic substance is in anaerobic environment, lower to microorganism fermentative action in certain temperature (more than 10C °), concentration (6%) and potential of hydrogen (pH value 6-7), a kind of inflammable gas producing, 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 has influence on the factor of created gase of methane-generating pit.Traditional methane-generating pit top cover is generally the cover plate made from concrete, the cover plate soil bonding sealing larger with the seam crossing viscosity of lid mouthful around.Such top cover weight is large, is inconvenient to open; And volume is large, has increased construction work amount and built expense.And need in use to collect in advance the marsh gas raw materials such as ight soil, then drop in methane-generating pit, cumbersome like this, workload is larger.
In sum, be necessary that design is a kind of simple in structure, cost of manufacture is low, wide adaptability, and top cover is lightweight, and can alleviate the methane-generating pit of workload, to address the above problem.
Utility model content
In view of this, it is a kind of simple in structure that the technical problems to be solved in the utility model is to provide, and cost of manufacture is low, wide adaptability, and top cover is lightweight, and can alleviate the methane-generating pit of workload.
The utility model solves the problems of the technologies described above by following technique means:
Removable top cover methane-generating pit of the present utility model, comprises pond body and top cover, and described pond body is provided with feed-pipe and discharge nozzle, and described pond body side surface inwall arranges carriage, and described top cover and carriage are tightly connected.
Further, described carriage comprises the chute being vertically arranged on inwall and the elevator that can slide along chute, and described elevator limits its maximum displacement upwards by being arranged at the limited block of body inwall upper end, pond.
Further, described top cover is soft bag.
Further, described soft bag is made by multilayer plastic film.
Further, described top cover offers gas collection hole, and described gas collection hole is provided with the effuser running through.
Further, described feed-pipe connects the faecal passageway in lavatory.
The beneficial effects of the utility model: removable top cover methane-generating pit of the present utility model, comprise pond body and top cover, described pond body is provided with feed-pipe and discharge nozzle, and described pond body side surface inwall arranges carriage, and described top cover and carriage are tightly connected.Described carriage comprises the chute being vertically arranged on inwall and the elevator that can slide along chute, and described elevator limits its maximum displacement upwards by being arranged at the limited block of body inwall upper end, pond.Described top cover is soft bag.Described soft bag is made by multilayer plastic film.Described top cover offers gas collection hole, and described gas collection hole is provided with the effuser running through.Described feed-pipe connects the faecal passageway in lavatory.The top cover of methane-generating pit of the present utility model is made by multilayer film, and top cover and carriage moving up and down are tightly connected, make top cover come up and down according to biogas amounts different in pond, the removable top cover good airproof performance of making like this, and simple in structure, cost of manufacture is low, lightweight, wide adaptability.And feed-pipe connects the faecal passageway in lavatory, makes the ight soil that people discharges directly to enter methane-generating pit, becomes marsh gas raw materials, convenient and swift, has alleviated greatly workload.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is perspective view of the present utility model.
Embodiment
Below with reference to accompanying drawing, the utility model is elaborated, as shown in Figure 1:
Removable top cover methane-generating pit of the present utility model, comprises pond body 1 and top cover 2, and described pond body is provided with feed-pipe 5 and discharge nozzle 6, and described pond body side surface inwall 4 arranges carriage, and described top cover 2 is tightly connected with carriage.To on the inwall of methane-generating pit, be provided with carriage, and top cover 2 and carriage are tightly connected, when the tolerance in methane-generating pit changes, carriage can drive top cover 2 to move up and down, and can not cause excessive pressure to top cover 2.
As the further improvement of technique scheme, described carriage comprises the chute being vertically arranged on inwall 4 and the elevator 3 that can slide along chute, and described elevator limits its maximum displacement upwards by being arranged at the limited block 8 of body inwall upper end, pond.Chute is set elevator is moved up and down easily, the height that limited block rises with restriction elevator is set.
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 top cover 2 offers gas collection hole, and described gas collection hole is provided with the effuser 7 running through.Effuser is used for after collecting biogas coming into operation.
As the further improvement of technique scheme, described feed-pipe 5 connects the faecal passageway in lavatory.Described methane-generating pit is to transform and make on the manure pit of peasant household, on manure pit, increase feed-pipe, discharge nozzle and airway etc., 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.
