Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
The present invention seeks to one and be positioned at operator cabin top, the slipstream utilizing operator cabin to produce with the negative pressure of cooling fan of engine windward cleans a kind of operator cabin overhead air-inlet type self-cleaning filter of filter core, be applied in engine aspirating system, effectively can improve the filtering effect of engine charge; Worked by the impact operations back flushing type dust removal apparatus of control switch again, reach the effect helping filter core self-cleaning.
According to the embodiment of the present invention, as shown in Figure 1-Figure 3, a kind of operator cabin overhead air-inlet type self-cleaning filter is provided.
Fig. 1 can show the structural principle of operator cabin overhead air-inlet type self cleaning filter.See Fig. 1, this operator cabin overhead air-inlet type self-cleaning filter, comprise filter cleaner enclosing cover (the filter cleaner enclosing cover 1 as in Fig. 1), outer lid hinge (outer lid hinge 2 as in Fig. 1), guide plate (guide plate 3 as in Fig. 1), rectangle filter core (the rectangle filter core 4 as in Fig. 1), blowback tracheae (the blowback tracheae 6 as in Fig. 1), guide plate (guide plate 7 as in Fig. 1), steam outlet pipe (steam outlet pipe 8 as in Fig. 1), operator cabin (operator cabin 9 as in Fig. 1), air-inlet cavity (air-inlet cavity 10 as in Fig. 1), wind chamber (the wind chamber 11 as in Fig. 1) and Pneumatic valve (Pneumatic valve 12 as in Fig. 1).
Filter cleaner entirety (i.e. filter body) divides three layers from the top down, the superiors be filter core layer (as the filter core layer in Fig. 1 1.), it is outlet chamber above filter core layer, filter core adopts common paper filter core and polyester fibre filter core, paper folding direction is parallel with vehicle heading, and filter core is detachable.Then be air inlet layer (as the air inlet layer in Fig. 1 2.), then be below water conservancy diversion lamella (as the water conservancy diversion lamella in Fig. 1 3.), the orientation of guide plate is vertical with the direction of filter core paper folding, is wind chamber below water conservancy diversion lamella.Air flow in air is in the acting in conjunction of wind speed and the speed of a motor vehicle, filter cleaner guide plate (guide plate 5 as Fig. 2) is entered into very high speed, this guide plate is positioned at foremost above suction port, for air-flow and the water that keeps off the rain of leading, also can stop that larger particles enters air-inlet cavity and wind chamber, play the effect of pre-flock.The air flow entering air-inlet cavity turns around upwards to enter filter core under the effect of motor negative pressure, and medium grain in air and dust drop in wind chamber under the effect of gravity and the effect of guide plate, have air flow at a high speed in wind chamber, blow off the grains of sand filter cleaner always.
Rectangle filter core can be dismantled, and filter cleaner enclosing cover can be opened under the effect of outer lid hinge, and filter core can take out replacing.Filter core outer surface attached to a lot of granules and dust under the long duration of action of normal air, wind chamber is connected with cooling fan of engine inlet end, the negative pressure produced when cooling fan can be allowed to rotate air draught is connected with wind chamber by connecting tube, whole like this wind chamber has become negative cavity, form forced ventilation, can make up like this speed of a motor vehicle lower time rear cabin negative pressure very little drawback, even if the speed of a motor vehicle very low (or under idle conditions) also can allow wind chamber keep high velocity air, these negative pressure high velocity airs help guide plate chamber to peel off granule and the dust of the attachment of filter core, play the effect that filter core is self-cleaning.
See Fig. 2, filter cleaner is overall to be directly connected with the exterior trimming parts (the operator cabin exterior trimming parts 1 as in Fig. 2) at operator cabin (operator cabin 7 as in Fig. 2) top due to the effect of cleaner brackets (cleaner brackets 2 as in Fig. 2), simply firm, easily install.
Fig. 2 can show the structure of back flushing type dust removal apparatus in this self-cleaning filter.Utilize back flushing type dust removal apparatus can force clean filter core, this back flushing type dust removal apparatus is made up of blowback tracheae (the blowback tracheae 6 as in Fig. 2), air cylinder (air cylinder 4 as in Fig. 2), air inlet electromagnetic valve (air inlet electromagnetic valve 3 as in Fig. 2), Pneumatic valve and control gear (control gear 8 as in Fig. 2), air cylinder provides the pressurized air of large discharge for clean filter core, for this reason, gas outlet tube all adopts heavy caliber tracheae and joint.
Fig. 3 can show the structure of Pneumatic valve in this self-cleaning filter.See Fig. 3, Pneumatic valve forms primarily of air valve (air valve 1 as in Fig. 3), suction tude (suction tude 2 as in Fig. 3), annular cylinder liner (annular cylinder liner 3 as in Fig. 3), tightening nut (tightening nut 4 as in Fig. 3), annular cylinder liner plug (the annular cylinder liner plug 5 as in Fig. 3), support (support 6 as in Fig. 3), return spring (return spring 7 as in Fig. 3), valve annular piston (the valve annular piston 8 as in Fig. 3) and suction tude aperture (the suction tude aperture 9 as in Fig. 3).The principle of this back flushing type dust removal apparatus is the apertures of pressurized gas by suction tude place, enter annular cylinder liner and promote valve annular piston movement, and valve annular piston moves together with air valve, final plant closure steam outlet pipe, after avoiding pressurized gas effect filter core, enter motor from " the dirty air " of filter core blowout.When suction tude do not have pressurized gas by time, air valve gets back to first state under the effect of return spring, does not affect the normal air inlet of motor.
The control gear of this back flushing type dust removal apparatus, comprise command switch, air inlet electromagnetic valve work indicator light and storage battery, push button magnetic switch selected by switch, can prevent driver from forgetting that closedown is opened for a long time, increases power consumption to car load storage battery and source of the gas; In addition, push-button switch can continuous control opening and closing gas circuit, forms pulsed air pressure and is conducive to clean filter core.Air inlet electromagnetic valve work indicator light lights when air inlet electromagnetic valve works.
The solution of the present invention, the beneficial effect that at least can reach is: the slipstream utilizing operator cabin to produce with the negative pressure of cooling fan of engine windward cleans a kind of self-cleaning filter of filter core, be applied in engine aspirating system, effectively can improve the filtering effect of engine charge; Also reach motor fuel-efficient, the object of fuel-economizing, reduce the maintenance cost of vehicle, add benefit.
The solution of the present invention, relatively simple for structure, use can be reequiped on existing vehicle, debug use, keep in repair more convenient.The effect of adding control switch can also realize the self-cleaning effect of back flushing type dust removal apparatus help filter core.
Through verification experimental verification, the solution of the present invention, directly saves manual maintenance and takes and annual nearly 10,000 yuan of filter core expense.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
