Embodiment
The preferred embodiments of the present invention are illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein preferred real
Apply example to be merely to illustrate and explain the present invention, be not intended to limit the present invention.
The present invention seeks to one kind at the top of driver's cabin, produced using negative pressure of the driver's cabin windward with cooling fan of engine
A kind of driver's cabin overhead air suction type self-cleaning filter of raw slipstream cleaning filter core, is applied to engine aspirating system
In, it can effectively improve the filter effect of engine charge；Pass through the impact operations back flushing type dust arrester of controlling switch again
Work, reach the effect of helping filter core self-cleaning.
According to embodiments of the present invention, as shown in Figure 1-Figure 3, there is provided a kind of driver's cabin overhead air suction type self-cleaning filtering
Device.
Fig. 1 can show the structural principle of driver's cabin overhead air suction type self cleaning filter.Referring to Fig. 1, the driver's cabin overhead
Air suction type self-cleaning filter, including cleaner enclosing cover (the cleaner enclosing cover 11 in such as Fig. 1), outer lid hinge are (outer in such as Fig. 1
Cover hinge 12), guide plate (guide plate 13 in such as Fig. 1), rectangle filter core (the rectangle filter core 14 in such as Fig. 1), blowback tracheae (such as
Blowback tracheae 16 in Fig. 1), flow deflector (flow deflector 17 in such as Fig. 1), escape pipe (escape pipe 18 in such as Fig. 1), driver's cabin
(driver's cabin 19 in such as Fig. 1), inlet chamber (inlet chamber 20 in such as Fig. 1), wind chamber (the wind chamber 21 in such as Fig. 1) and operated pneumatic valve
Device (Pneumatic valve 22 in such as Fig. 1).
Cleaner overall (i.e. filter body) divides three layers from the top down, and the superiors are filter core layer (the filter core layer in such as Fig. 1
23) it is, outlet chamber above filter core layer, filter core uses common paper filter core and polyester fiber filter core, and paper folding direction travels with vehicle
Direction is parallel, and filter core is detachable.Followed by enter gas-bearing formation (entering gas-bearing formation 24 in such as Fig. 1), it is water conservancy diversion lamella further below (in such as Fig. 1
Water conservancy diversion lamella 25), the orientation of flow deflector is vertical with the direction of filter core paper folding, is wind chamber below water conservancy diversion lamella.In air
Air flow in wind speed and the collective effect of speed, the cleaner deflector (water conservancy diversion in such as Fig. 2 is entered with very high speed
Plate 35), the deflector is located above the air inlet of front end, for being oriented to air-flow and the water that keeps off the rain, can also stop larger particles
Into inlet chamber and wind chamber, play a part of pre-flock.Air flow into inlet chamber turns around in the presence of machine negative pressure is started
Filter core is upwardly into, and the medium grain and dust in air are dropped in the presence of the effect of gravity and flow deflector in wind chamber,
There is the air flow of high speed in wind chamber always, the grains of sand are blown off cleaner.
Rectangle filter core can be dismantled, and cleaner enclosing cover can be opened in the presence of outer lid hinge, and filter core can be taken off changing.
Filter core outer surface is attached to many little particles and dust, wind chamber and engine cool wind under the long duration of action of normal air
Fan inlet end is connected, and negative pressure caused by cooling fan rotation air draught can be allowed to be connected by connecting tube with wind chamber, so whole
Individual wind chamber forms forced ventilation into negative pressure cavity, can so make up speed it is relatively low when rear cabin negative pressure very little the drawbacks of,
Even if speed very low (or under idle conditions) wind chamber can also be allowed to keep high velocity air, these negative pressure high velocity airs help water conservancy diversion
Piece chamber peels off the little particle and dust of the attachment of filter core, plays the self-cleaning effect of filter core.
Referring to Fig. 2, the overall effect and driver's cabin due to cleaner brackets (cleaner brackets 32 in such as Fig. 2) of cleaner
Exterior trimming parts (the driver's cabin exterior trimming parts 31 in such as Fig. 2) at the top of (driver's cabin 19 in such as Fig. 2) is directly connected to, simple firm, easily
Installation.
Fig. 2 can show the structure of back flushing type dust arrester in the self-cleaning filter.Can using back flushing type dust arrester
To force to clean filter core, the back flushing type dust arrester is by blowback tracheae (the blowback tracheae 36 in such as Fig. 2), gas bomb (in such as Fig. 2
Gas bomb 34), air inlet electromagnetic valve (air inlet electromagnetic valve 33 in such as Fig. 2), Pneumatic valve and control device be (in such as Fig. 2
Control device 37) composition, gas bomb provides the compressed air of big flow for cleaning filter core, therefore, gas outlet tube uses greatly
Bore tracheae and joint.
Fig. 3 can show the structure of Pneumatic valve in the self-cleaning filter.Referring to Fig. 3, Pneumatic valve master
Will be by air valve (air valve 41 in such as Fig. 3), air inlet pipe (air inlet pipe 42 in such as Fig. 3), the annular cylinder liner (ring in such as Fig. 3
Shape cylinder sleeve 43), clamp nut (clamp nut 44 in such as Fig. 3), annular cylinder liner plug (the annular cylinder liner plug in such as Fig. 3
45), support (support 46 in such as Fig. 3), return spring (return spring 47 in such as Fig. 3), valve annular piston are (in such as Fig. 3
Valve annular piston 48) and air inlet pipe aperture (the air inlet pipe aperture 49 in such as Fig. 3) composition.The original of the back flushing type dust arrester
Reason is gases at high pressure by the aperture at air inlet pipe, and valve annular piston movement is promoted into annular cylinder liner, and valve annular is living
Plug and air valve move together, final plant closure escape pipe, after avoiding gases at high pressure effect filter core, from " dirty air " of filter core blowout
Into engine.When air inlet pipe do not have gases at high pressure by when, air valve returned in the presence of return spring just next state, no
Influence the normal air inlet of engine.
The control device of the back flushing type dust arrester, including command switch, air inlet electromagnetic valve relay indicating light and battery,
Switch selects push button electromagnetic switch, can prevent driver from forgetting to close to open for a long time, to vehicle battery and source of the gas increase work(
Consumption；In addition, push-button switch can be opened and closed gas circuit with continuous control, form pulsed air pressure and be advantageous to clean filter core.Air inlet electromagnetism
Valve relay indicating light lights when air inlet electromagnetic valve works.
The solution of the present invention, the beneficial effect that can at least reach are：Using driver's cabin windward and cooling fan of engine
Negative pressure caused by slipstream cleaning filter core a kind of self-cleaning filter, be applied in engine aspirating system, Ke Yiyou
The filter effect of the raising engine charge of effect；Also reached that engine is fuel-efficient, the purpose of fuel-economizing, reduce the maintenance of vehicle into
This, adds benefit.
The solution of the present invention, it is relatively simple for structure, use can be reequiped on existing vehicle, adjustment is compared using, maintenance
It is convenient.Along with the effect of controlling switch can also realize the effect of back flushing type dust arrester helps filter core self-cleaning.
Experiment proves that the solution of the present invention, directly saving manual maintenance is taken and filter core expense is annual nearly 10,000 yuan.
Finally it should be noted that：The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention,
Although the present invention is described in detail with reference to the foregoing embodiments, for those skilled in the art, it still may be used
To be modified to the technical scheme described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic.
Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., it should be included in the present invention's
Within protection domain.
