Description
Technical field
The present invention relates to a kind of filter, specifically refer to the right air filter of a kind of fast Kaitian.
Background technology
The normal right air filter of a kind of fast Kaitian that uses in the transmission & distribution of city gas.Advance the natural gas of gas distribution station, because carry at a distance or other reason, always (natural gas produces erosion to the pipeline inwall with a small amount of micron order or submicron order impurity, upper level gas gathering station, purification plant or gas distribution station on natural gas separate, residual impurity after dedusting, purification) the normal even running of impact station internal pressure-regulating device, metering device, so at last one station to user's air feed, all must come gas to carry out purifying and dedusting to upper level, to guarantee tight gas supply.
At present, the filter on market, stablize air feed for guaranteeing the precision equipments such as pressure regulation, metering, and the workman that needs repairing need open the cleaning filter filter core continually, and workload is very heavy.In addition, be subjected to the restriction of sealing property and structural strength, oneself is not suitable for blind flange bolt type filter in the filter that pressure is higher, barrel dliameter is larger.
Summary of the invention
The invention provides the right air filter of a kind of fast Kaitian, solve when natural gas filter cleans the problem of frequently opening and causing working strength to increase, reach the purpose of opening fast or closing filter.
Purpose of the present invention reaches by the following technical programs:
The present invention includes cylindrical shell and upper cover, described cylindrical shell is provided with air inlet and gas outlet, cylinder body bottom is provided with blowoff valve, and the inside of cylindrical shell is equipped with filter core, and described filter core is communicated with air inlet, gas outlet is communicated with inner barrel, described cylindrical shell is connected with upper cover by lifting bolt, and upper tops is connected with handwheel by screw rod, and upper tops coordinates with screw flight, also comprise the turning arm be arranged on cylindrical shell, the end of turning arm is connected with screw flight.The top of cylindrical shell is connected and fixed by welding and outside installing rack, the bottom of cylindrical shell is provided with blowoff valve, can not only play the effect of emptying pressure release, the solid particle or the liquid impurity that in filter core, isolate can also be got rid of to convenient clean and maintenance to filter core; The dust of the larger particles in the natural gas that air inlet passes through or impurity are done inertia motion with the natural gas flow at high speed, and when air-flow ran into barrier and detours, dust departed from airflow direction because of inertia and bump against the filter wire of filter online, and barred is in net; After the filtration of one-time surface formula, natural gas continues by a plurality of filtering holes on the multiple filtration silk screen, filtering holes has many bending channels, the number of plies is more, be that filter area is larger, the dust in natural gas constantly bumps with filtering silk screen, and very little granule dust is also done random Brownian movement, the kinetic energy of dust constantly reduces, until can not move, is stuck in and filters in silk screen; Finally by the natural gas filtered, passing through the gas outlet discharge filter, the impurity in filter core is got rid of by blowoff valve, makes its running stable.
After long-time the use, need to clean filter, rotating suspension ring bolt separates upper cover and cylindrical shell, regulate simultaneously the handwheel of upper tops, by upper cover ascending one segment distance, then open by upper cover and cylindrical shell dislocation by rotating turning arm, then take out fast filter core and clean; With traditional flange bolt, be connected and compare, the time that filter is uncapped shortens greatly, has reduced workman's labour intensity, has improved operating efficiency.
Further, also comprise the end socket arranged between cylindrical shell and upper cover, end socket is provided with the O RunddichtringO.Because upper cover is that bolt is connected with handwheel, in use be easy to the pressure release of leaking gas, so end socket and O RunddichtringO are installed to ensure pressure stability in cylindrical shell, air tight between cylindrical shell and upper cover.
Further, described filter core top is inclined plane, inclined plane and horizontal plane angle at 45 °, and described air inlet is over against inclined plane, and filter core is communicated with inner barrel by inclined plane.Filter core adopts the design of upper end open, lower end closure, bottom at cylindrical shell is provided with inclined plane, inclined plane is over against air inlet, natural gas directly enters filter core from air inlet, filtration silk screen by multilayer carries out filtration treatment, thereby increased the contact area of natural gas and filter core, be convenient to natural gas and enter into fast filter core and filter.
Further, the bottom of described cylindrical shell is hemispherical, and described blowoff valve is arranged on the minimum point of the bottom of described housing.Usually cylinder body bottom is made as plane, easily causes the impurity filtered to be piled up in convenient the placement, is difficult to from blowoff valve, getting rid of; The cylinder body bottom of hemispherical design can make impurity under the effect of self gravitation fast from blowoff valve, flowing out, the cleaning of convenient filter.
Further, also comprise the differential pressure gauge that is arranged on drum surface, the two ends of described differential pressure gauge are connected with air inlet, gas outlet respectively.Usually, filter can regularly clean, but, because uncertainty causes the breakage of filter core net, does not carry out in time dress watch and can cause the filter effect of natural gas greatly to reduce; Differential pressure gauge can be pointed out the change value of pressure of filter rear and front end in real time, for the filter suitable clean period of statistics provides scientific basis, plays cost-saving, the time, and the effect maintained easily, can save energy and reduce the cost effectively.
The present invention compared with prior art, have following advantage and a beneficial effect:
1, the present invention includes cylindrical shell and upper cover, described cylindrical shell is provided with air inlet and gas outlet, cylinder body bottom is provided with blowoff valve, and the inside of cylindrical shell is equipped with filter core, and described filter core is communicated with air inlet, gas outlet is communicated with inner barrel, described cylindrical shell is connected with upper cover by lifting bolt, and upper tops is connected with handwheel by screw rod, and upper tops coordinates with screw flight, also comprise the turning arm be arranged on cylindrical shell, the end of turning arm is connected with screw flight; After long-time the use, need to clean filter, rotating suspension ring bolt separates upper cover and cylindrical shell, regulate simultaneously the handwheel of upper tops, by upper cover ascending one segment distance, then open by upper cover and cylindrical shell dislocation by rotating turning arm, then take out fast filter core and clean; With traditional flange bolt, be connected and compare, the time that filter is uncapped shortens greatly, has reduced workman's labour intensity, has improved operating efficiency.
2, the present invention also comprises the differential pressure gauge that is arranged on drum surface, and the two ends of described differential pressure gauge are connected with air inlet, gas outlet respectively; Differential pressure gauge can be pointed out the change value of pressure of filter rear and front end in real time, for the filter suitable clean period of statistics provides scientific basis, plays cost-saving, the time, and the effect maintained easily, can save energy and reduce the cost effectively.
