For achieving the above object, the technical scheme that the utility model is taked is:
A kind of methane gas extraction pipeline automatic bleeder, comprise solid-liquid-gas separating device and jettison gear, described solid-liquid-gas separating device comprises pipe joint, valve, solid-liquid-gas separation bin and gross porosity filter screen, described jettison gear comprises the storehouse that discharges water, spherical float, counterweight, connecting rod, piston, separating opening, inclined-plane and dewatering outlet, described pipe joint is connected with extraction pipeline by valve, described solid-liquid-gas separation bin top is provided with gross porosity filter screen, spherical float is provided with in described solid-liquid-gas separation bin, described spherical float connects counterweight and tapered piston by connecting rod, the conical surface is provided with bottom described solid-liquid-gas separation bin, separating opening is provided with bottom the described conical surface, described tapered piston and cone match, described conical surface bottom is provided with the storehouse that discharges water, inclined-plane is provided with bottom the described storehouse that discharges water, the described side, storehouse that discharges water is provided with dewatering outlet.
The utility model has following beneficial effect:
Rely on the gravity of buoyancy of water and counterweight, have developed a kind of methane gas extraction pipeline automatic bleeder.The utility model is applicable to the automatic draining of sizes negative-pressure pipeline, and structure is comparatively simple, directly can discharge ickings, reduces human intervention, time saving and energy saving, for the discharge of percolating water in gas pumping pipeline and ponding of drilling provides a great convenience.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of methane gas extraction pipeline automatic bleeder of the utility model embodiment.
Detailed description of the invention
In order to make the purpose of this utility model and advantage clearly understand, below in conjunction with embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
With reference to Fig. 1, this detailed description of the invention is by the following technical solutions: a kind of methane gas extraction pipeline automatic bleeder, comprise solid-liquid-gas separating device and jettison gear, described solid-liquid-gas separating device comprises pipe joint 3, valve 2, solid-liquid-gas separation bin 6 and gross porosity filter screen 4, described jettison gear comprises the storehouse 12 that discharges water, spherical float 7, counterweight 9, connecting rod 8, piston 11, separating opening 13, inclined-plane 14 and dewatering outlet 15, described pipe joint 3 is connected with extraction pipeline 1 by valve 2, described solid-liquid-gas separation bin 6 top is provided with gross porosity filter screen 4, spherical float 7 is provided with in described solid-liquid-gas separation bin 6, described spherical float 7 connects counterweight 9 and tapered piston 11 by connecting rod 8, the conical surface 10 is provided with bottom described solid-liquid-gas separation bin 6, separating opening 13 is provided with bottom the described conical surface 10, described tapered piston 11 coordinates with the conical surface 10, the described conical surface 10 bottom is provided with the storehouse 12 that discharges water, inclined-plane 14 is provided with bottom the described storehouse 12 that discharges water, the described side, storehouse 12 that discharges water is provided with dewatering outlet 15.
This concrete enforcement, before being connected with extraction pipeline 1, valve 2 is in closed condition, and pipe joint 3 is connected with extraction pipeline 1, and the Action of Gravity Field piston 11 due to counterweight 9 seals the conical surface 10 of solid-liquid-gas separating device, and dewatering outlet 15 is in open mode all the time.After connecting extraction pipeline 1, open valve 2, in solid-liquid-gas separation bin 6, be in negative pressure state, separating opening 13 by counterweight 9 and piston 11 seal.When having water to exist in extraction pipeline, automatic bleeder will be entered by pipe joint 3, wherein relatively large cinder is tackled by gross porosity filter screen 4, ensure the normal operation of below jettison gear, when accumulating a certain amount of water in solid-liquid-gas separation bin 6, mentioned by piston 11 under the buoyancy of spherical float 7, ponding and broken coal bits enter and discharge water in storehouse 12, due to the existence on inclined-plane 14, ickings directly will be discharged by dewatering outlet 15 with ponding.
This concrete gravity implementing support buoyancy of water and counterweight, have developed a kind of methane gas extraction pipeline automatic bleeder.The utility model is applicable to the automatic draining of sizes negative-pressure pipeline, and structure is comparatively simple, directly can discharge ickings, reduces human intervention, time saving and energy saving, for the discharge of percolating water in gas pumping pipeline and ponding of drilling provides a great convenience.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
