Abstract
The utility model relates to a movable cover arranged in a top of a firedamp pool. The utility model comprises a discal supporting seat (1), a boiler shaped movable cover (2) and a connecting bolt (3). When making irrigation for the pool, the discal supporting seat (1) and the connecting bolt (3) are fixed in the vault center of gas-store room of the firedamp pool. And then use the connecting bolt (3) fix the boiler shaped movable cover (2) on the discal supporting seat (1). The interface between the top of the discal supporting seat (1) and the below of the boiler shaped movable cover (2) is a smooth face. The design guarantees the sealing requirement of the cover of the firedamp pool and the repair convenience for the operation of the pool at any moment. The device can avoid the cover-clashing situation because of the unsealing pool cover.
Description
Technical field
The utility model relates to a kind of removable cover that is installed in the methane-generating pit top.
Background technology
The methane-generating pit removable cover is one of vitals of methane-generating pit, its major function is: 1, when methane-generating pit reloads greatly or keep in repair inside, after opening removable cover, the charging and discharging mouth communicates with the removable cover mouth, by remaining gas in the favourable discharge of the air blast pond, can guarantee to be engaged in and reload or serviceman's safety, simultaneously, removable cover mouth transparent surface is bigger, and is easy to operate; 2, fermented liquid surface crust is thicker in the pond, when influencing aerogenesis, can open removable cover, breaks the excrement shell, stirs liquid manure, makes aerogenesis normal.Whether the structure and layout of methane-generating pit removable cover are reasonable, directly have influence on the factor of created gase of methane-generating pit.Traditional methane-generating pit removable cover is generally made with concrete, the shape of cover plate such as plug for vacuum bottle, and the circular cover that the end face diameter is big, the bottom surface diameter is little, when laying, the seam crossing with the lid mouth around the cover plate seals with the bigger soil bonding of viscosity.Such one is poor sealing, leaks gas from the lid limit in order to prevent at ordinary times, be put on to cover on the limit with clay to seal, and carries out water shut off treatment, because the water seal technical difficulty is big, gas leak phenomenon often takes place water seal position, pond, thereby has reduced the gas production rate of methane-generating pit; The 2nd, reload and bigger because of removable cover weight when keeping in repair, give and open removable cover and bring difficulty; The 3rd, volume is bigger, has increased the construction work amount and has built expense;
The utility model content
The purpose of this utility model is to avoid above-mentioned deficiency, and a kind of good airproof performance, the conveniently maintenance of reloading are provided, and improves the methane-generating pit removable cover of factor of created gase.
The utility model is achieved in that the utility model is made up of ready-formed disc bearing (1), pot shape removable cover (2) and joint bolt (3).When the pond is watered, disc bearing (1) and joint bolt (3) are fixed on vault central authorities between the methane-generating pit air storage, with joint bolt (3) pot shape removable cover (2) is fixed on above the disc bearing (1), the contact surface of disc bearing (1) end face and pot shape removable cover (2) bottom surface is a shiny surface.Maintenance at any time after seal request and pond operate when having guaranteed the methane-generating pit capping like this is convenient, has avoided the lid water seal of pond, pond sternly not dash the phenomenon of covering.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is a front view of the present utility model;
Fig. 2 is a vertical view of the present utility model;
Fig. 3 is the front view of the utility model disc bearing (1);
Fig. 4 is the vertical view of the utility model disc bearing (1);
Fig. 5 is the front view of the utility model pot shape removable cover (2);
Fig. 6 is the vertical view of the utility model pot shape removable cover (2).
Among the figure: 1. disc bearing, 2. pot shape removable cover, 3. joint bolt, 4. ear handle, 5. connecting hole.
Embodiment
With reference to accompanying drawing, the utility model is made up of ready-formed disc bearing (1), pot shape removable cover (2) and joint bolt (3).When the pond is watered, disc bearing (1) and joint bolt (3) are fixed on vault central authorities between the methane-generating pit air storage, with joint bolt (3) pot shape removable cover (2) is fixed on above the disc bearing (1), the contact surface of disc bearing (1) end face and pot shape removable cover (2) bottom surface is a shiny surface.Uniform several connecting holes of disc bearing (1) (5); Made things convenient for when installing and lifted, on the top of pot shape removable cover (2), be provided with ear handle (4) for lid; Disc bearing (1) and the available cast iron of pot shape removable cover (2) are made, but also glass reinforced plastic is made.
The methane-generating pit removable cover has guaranteed that the several years of continuous fermentation process normally moves, realize gravity flow, circulation running shell breaking function by pressure, buoyancy and thrust interaction and the variation that rationally utilizes pool gas, liquid, strengthen feed-pipe discharge nozzle geometrical dimension, ramp angles realizes the effect of water pressure house safety valve at the bottom of reducing feed-pipe angle, cloth spreader plate angle and pond, can substitute former water seal tank lid safety valve function.Cover completely in the pond under the condition of lattice sealing, methane-generating pit can be given full play to the microbiological anaerobic fermentative action, has improved the raw material factor of created gase.
The methane-generating pit of methane-generating pit removable cover is installed, guaranteeing the raw material carbon-nitrogen ratio 15-25 that feeds intake: 10, feed liquid fermentation concentration 6%-12%, fermented feed liquid acid degree of subtracting 6-8PH value, leavening temperature 5-35 ℃ is waited under the biogas fermentation primary condition in the methane-generating pit, and the raw material factor of created gase is every to increase by 0.05 meter than the methane-generating pit with the traditional activity lid round the clock
3More than, year can voluminous biogas 100 meters
3More than.Solved the methane-generating pit difficult sealing, problems such as frequent gas leakage have made things convenient for the maintenance of reloading of methane-generating pit.
Use the utility model, methane-generating pit can reduce by 20 centimetres of whole pond height, has saved whole pond construction work amount, has reduced and has built the pond cost.
