Background technology
Along with the Chinese society expanding economy, urban track traffic has obtained big popularizing and popularization.Be to guarantee economy and the dynamic index and the reliability of driving engine, need be the special air-filtering equipment of configuration such as the piston of driving engine and cylinder sleeve.
The efficient of the engine air filter group that adopts on the existing locomotive is lower, can not guarantee effectively that the cleaning of q.s, fresh air reach in the driving engine into the car.After long-time the use, more easily cause the wearing and tearing of the critical elements such as piston ring, piston, cylinder sleeve of locomotive engine, shortened its service life.
As the patent formerly of following content disclosed, the patent No. 03227349.5, name is called automotive gas turbine gas compression unit, its scheme is the three-stage filtration device that is serially connected with louver filter, " V " type filter and fine filter in the air system of automotive gas turbine casing, and design has horizontal expansion joint and the vertical expansion joint that comprises level and vertical expansion joint, with at rough weather, particularly adapt to many dusts, the area of dust storm.
In the above-mentioned formerly disclosed scheme, though dispose the three-stage filtration device, but it is not good for the dust storm filter effect, the sand material that material is bigger still can enter into the air channel, and the fixed form of filtering installation is simple, more easily shake falls in the locomotive operation process, and bad for the sealing property of rainwater, is difficult to clean and handling labor at the integral filter device.
The utility model content
Overhead described in the utility model is prevented the dust storm air inlet system, be to address the above problem with deficiency whole air inlet system is installed in the locomotive top, in the monosymmetric structure of roof, be provided with the filtering window that is fixedly connected on roof by folding, in the micronic filter fixing body is formed, micronic filter is socketed on the mount pad that connects induction opening, vertically be fixed with array in the framework inside of filtering window and return palace formula ventilation blade, the ventilation blade has the cross sectional shape of circular arc, and every group of ventilation blade partial transposition be oppositely arranged.
One of design goal of the present utility model is, improves filter efficiency and precision at dust storm under the prerequisite of increase suction quantity, and outside by the filtering window the husky material of major part being blocked in, and raising is for the sealing effectiveness of rainwater.
Another design goal is, improves the fastening effect of filtering installation and roof, avoids shake in the locomotive high-speed cruising process phenomenon that falls.
Also attainable design goal is to reduce the complex structure degree of whole air inlet system, easy to clean and maintenance, the service life of prolongation micronic filter.
For realizing above-mentioned design goal, the keystone configuration of the anti-dust storm air inlet system of described overhead is:
The anti-dust storm air inlet system integral installation of described overhead comprises the symmetrical structure that is arranged on the roof both sides at the locomotive top of guideway vehicle, comprising form by filtering window, micronic filter fixing body, inlet channel is formed and bend pipe is formed.
The upper side frame of described filtering window is fixedly connected on the sidepiece of roof by folding;
Described inlet channel is formed the inwall that top is connected roof, and the bottom is connected in bend pipe by flange and forms;
Described bend pipe is communicated in the inlet chamber of driving engine downwards;
Described micronic filter fixing body is formed the internal chamber by roof, the base plate, the inlet channel that are welded on the roof below are formed, side plate and filtering window surround, the two sides that inlet channel is formed are provided with induction opening, be connected with mount pad on induction opening, micronic filter is socketed on the mount pad.
Improvements of the present utility model are, in the framework inside of described filtering window, vertically are fixed with array and return palace formula ventilation blade, and the ventilation blade has the cross sectional shape of circular arc, and every group of ventilation blade partial transposition be oppositely arranged.
Use the anti-dust storm air inlet system of overhead of such scheme feature, form two-stage filtering layer at the locomotive top.First order filtering is the filtering window of vertical installation.Second stage filtering is a micronic filter, and it is installed in the top cover below, the base plate top.
The air of vent external enters from the filtering window, enters into the micronic filter fixing body again after filtering.Wherein bigger sand and dust particle is filtered out and wanders vent external by the filtering window.
Through the air admission micronic filter after the coarse filtration, through filtering, the air of the thorough filtering of process is pooled in the inlet channel composition in the lump once more, the final bend pipe composition that connects driving engine that flows to.
Further improvement project is that the roof sidepiece in described filtering window both sides welds a double-screw bolt respectively; One end that pressing plate is installed is socketed on the double-screw bolt, and the other end is by on the frame that is pressed in described filtering window;
A sheathed acorn nut on the double-screw bolt on pressing plate is installed connects a spring shim between acorn nut and installation pressing plate.
Described filtering window links to each other with roof by folding, after upwards opening, rotates to surpass and is supported on behind 90 degree on the top cover and is unlikely to backspace.Under the situation that acorn nut is not tightened, pressing plate can be on double-screw bolt rotates and can be by the frame that is pressed in the filtering window, thereby the filtering window is fixed downwards, even the locomotive high-speed cruising, the filtering window also can be compressed by pressing plate and can not produce vibrations thereupon.
In order to prevent pressing plate landing in locomotive high-speed cruising process, and cause the filtering window to shake thereupon, be welded with a stop on the frame of described filtering window, this stop is positioned at the below of double-screw bolt.Then the pressing plate side direction that can only make progress rotates, and when pressing plate forwards the stop position to, tightens acorn nut and can compress described filtering window.
In order to guarantee the sealing between described filtering window and the locomotive header, to prevent that dust and rainwater from entering into the inside that the micronic filter fixing body is formed by the gap, the upper frame two ends of described filtering window are connected with roof by cylindrical folding respectively, between the upper side frame of described filtering window and roof, form an indent groove, a sealing band is set in groove.
Form inside at described micronic filter fixing body, described mount pad has a clamping rings, and the screw rod that stretches out laterally; Described micronic filter, its front end is fixedly connected on the annulus of mount pad, and bears against on the induction opening that inlet channel is formed by a seal ring; The screw rod of described mount pad inserts the circular hole of micronic filter rear end, is connected sealing with fly nut by pad.
When reducing filtered air, the intake air restriction that air is produced and increase suction quantity, described micronic filter is cylindrical-conical paper air cleaner.
Content to sum up, the anti-dust storm air inlet system of described overhead has the following advantages:
1, increasing under the prerequisite of suction quantity, improving to the filter efficiency of dust storm and precision and to the sealing effectiveness of rainwater.
2, improve the fastening effect of filtering installation and roof, can avoid the shake of filtering window in locomotive high-speed cruising process to fall.
3, reduce the structure difficulty of whole air inlet system, cleaning and maintenance to micronic filter easy to implement prolong operating cycles.
Intake air restriction when 4, effectively reducing filtered air, manufacturing cost is lower.
