Description
Technical field
The utility model relates to field of internal combustion engine, especially a kind of secondary filter and use the air-strainer of this secondary filter.
Background technique
In the required three kinds of media of vehicle motor (internal-combustion engine) work, the consumption of air is maximum, and the required air of engine operation is directly from atmosphere.And airborne suspending particulate matter can reduce the power of motor, the wearing and tearing of aggravation engine interior, thereby air must pass through dust removal and filtration before getting into motor, the clean filtering of air is particularly important.
Application number is that the Chinese patent of 201010587254.X discloses a kind of rotating component and used the strainer and the filter cleaner of this rotating component; Said filter cleaner comprises rotating component and secondary filter; Said rotating component comprises the housing of tubular, and the internal face of housing is provided with the dust-collecting plate of arc, and an end of dust-collecting plate is close to the internal face of housing; Form a dust-discharging mouth between the internal face of the other end and housing, thereby make formation one dust collection chamber between the internal face of dust-collecting plate and housing; Also be equipped with support in the housing and be equipped with rotor through the support coaxial rotation, said rotor circumferentially on radially disperse and be laid with swivel plate, swivel plate is equipped with scraper plate away from an end of rotor; Also be equipped with motor (can omit under the certain situation) on the support; Motor and rotating component are in transmission connection and rotate with the rotary driving device; Lower part of frame is provided with intake grill and fixedly is equipped with impeller in its intake grill place, and impeller is used to change the flow direction that gets into the air-flow in the housing, makes it form swirling eddy; Thereby foreign material heavier relatively in the air-flow are got rid of to the internal face of housing under action of centrifugal force; Finally scraped into dust collection chamber and discharge by scraper plate, the lower end of housing has the rotor exhaust outlet, and the swirling eddy that gas forms after the rotating component cleaning is discharged from said rotor exhaust outlet; Said secondary filter comprises that the smart filter housing body and coaxial of tubular is assemblied in the filter core in the said smart filter housing body, upwards is provided with in the week of said smart filter housing body on the essence filter suction port that is used to receive air-flow and the Yu Qijing filter suction port and is connected with cyclone tube; Said cyclone tube comprises the interior pipe and the outer tube of coaxial setting; The external diameter of pipe is less than the internal diameter of outer tube in said; One end of interior pipe is plugged in the outer tube and through the cyclone tube impeller on the pipe in coaxial being fixedly arranged on and is fixedly connected with outer tube; Wherein the cooperation place of inner and outer pipes forms the cyclone tube intake grill, and outer tube is the cyclone tube dust exhaust port away from an end of interior pipe, and interior pipe is the cyclone tube air outlet away from an end of outer tube; During use; (being the cyclone tube suction port) gets into cyclone tube to air-flow from the gap between the inner and outer pipe, forms reverse swirling eddy through described cyclone tube impeller then, and promptly air-flow is managed the swirling eddy that screws out through forming behind the said cyclone tube impeller in said; Be discharged from from the cyclone tube dust exhaust port thereby make impurity in the air-flow under action of centrifugal force, got rid of the internal face that to the internal face of outer tube and under the effect of inertial force and air inlet, is pasting outer tube, discharge from the cyclone tube air outlet through the air-flow of cleaning; The air outlet of said cyclone tube is connected with the essence of said secondary filter filter suction port; Its cyclone tube suction port is connected with the air outlet of rotating component; Since the cyclone tube suction port of said cyclone tube be positioned at its week upwards, the cyclone tube air outlet is to be positioned at an end; Therefore described cyclone tube is to disperse extension along the radially outward of secondary filter, and this has then increased the volume of filter cleaner greatly, requires to conflict with the compactedness of present vehicle; In addition; Because all being the fixed positions (smart filter intake grill) over against secondary filter, the cyclone tube air outlet of described cyclone tube locates; The air-flow of therefore discharging from cyclone tube has also caused impact to the local location of the filter core of secondary filter, remaining impurities even can break can filter core and the relative position of suction port of cyclone tube in the air-flow, in addition; Because filter core is local work, this then makes it can't bring into play best service behaviour.Generally speaking, above-mentioned filter cleaner in use has following two problems at least: 1) can not make full use of secondary filter space on every side, cause the volume of filter cleaner excessive, can't satisfy the requirement to the compact structure of vehicle; 2) make the filter core load of secondary filter inhomogeneous, be prone to cause the local damage of filter core and can't make the best service behaviour of filter core performance.
