Description
Technical field
The utility model belongs to internal-combustion engine primary filter and dedusting and purifying device, particularly the novel round air intake type air prefilter of one.
Background technique
Current China is widely used in the air prefilter of engineering machinery, Agricultural Machinery Equipment, and its separation effect is by the restriction of technical specifications, and separating effect is not good, and function singleness.Measure by the existing professional standard of China, the separation effect of the hat type of market sale, basin room and rotational flow pipe type strainer is all about 60 ~ 85%, poorer to the filtering effect of micronic dust, especially when sand and dust and severe environmental pollution.The Degree of Accord Relation of air purification is to the ride quality of internal-combustion engine, and reducing internal combustion engine operation wearing and tearing is important guarantees to improving internal-combustion engine life-span.Paying attention to and developing efficient air prefilter is that China advocates one of effective measure of energy-saving and emission-reduction, and existing filtration device structure is complicated, high cost, assembles loaded down with trivial details, poor sealing, causes row's leak-off effect, have impact on the life-span of internal-combustion engine.
Model utility content
The purpose of this utility model is to provide a kind of low cost, and volume is little, compact structure, the round air intake type air prefilter that filter efficiency is high.
The purpose of this utility model realizes as follows:
A kind of round air intake type air prefilter, comprise guiding bar, interface, rain cover and impeller, above-mentioned guiding bar and rain cover are tightly connected by bayonet socket and form dust separation chamber, impeller is fixedly connected with guiding bar by bolt, interface is by screw and the releasable connection of guiding bar, and above-mentioned rain cover top is provided with fan-shaped dust-discharging mouth.
The dust-discharging mouth of above-mentioned rain cover is arranged on the corner of end face and cylndrical surface, and is formed fan-shaped in diametric(al).
The dust-discharging mouth place of above-mentioned rain cover is provided with parabolic shape blend stop, and is provided with stiffening rib between blend stop and rain cover.
Above-mentioned impeller has 3-5 guide vane.
Advantage of the present utility model: guiding dust discharge seat is once through moulding technology manufacture, greatly improves component interchangeability and after assembling, work newly can be stablized; Interface size can according to air filter of internal combustion engine intake interface size configure, not only on filter precision and efficiency, there is significant raising, windy rain weather conditions are descended and can keep good working order simultaneously, not only can dust discharge its perfect water-resistant performance but also the rain work of windy rain area machinery can be met simultaneously, extend the maintenance cycle of air filtering core, easy to use; Rain cover dust-discharging mouth and air inlet and the anisodiametric advanced design of disengagement chamber, can effectively prevent impurity secondary in air from sucking, the diameter of guiding bar is much smaller than the disengagement chamber diameter of rain cover, reduce air inlet sectional area and increase air velocity, further raising wheel speed, thus increasing the centrifugal force of dust, separating effect is better, and the dust of discharge flies away farther.
Accompanying drawing explanation
In order to make content of the present invention more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation, wherein:
Fig. 1 is the structural representation that the utility model is implemented;
Fig. 2 is rain cover schematic diagram in figure.
Fig. 3 is that mixing air of the present utility model is separated schematic diagram.
Mark in figure: guiding bar (1), interface (2), rain cover (3), impeller (4), bolt (5), dust-discharging mouth (31), blend stop (32), stiffening rib (33).
Embodiment
See Fig. 1 and Fig. 2, this novel round air intake type air prefilter, comprise guiding bar 1, interface 2, rain cover 3 and impeller 4, above-mentioned guiding bar and rain cover are tightly connected by bayonet socket, impeller is fixedly connected with guiding bar by bolt 5, interface is by screw and the releasable connection of guiding bar, and above-mentioned rain cover inside top is provided with dust-discharging mouth.Dust-discharging mouth 31 place of above-mentioned rain cover is provided with parabolic shape blend stop 32, is provided with stiffening rib 33 between blend stop and rain cover.Above-mentioned impeller has 4 rotation blades.
See Fig. 3, this its working procedure novel is: after internal-combustion engine is started working, air-breathing program produces negative pressure, the air sucked enters prefilter from guiding bar 1, through guiding piece, water conservancy diversion is carried out to air and form eddy current, impeller 4 with air movement direction voluntarily High Rotation Speed time turn scooter 80000r/m, therefore powerful centrifugal force is produced, make the dust in suction air and impurity under centrifugal action, throw to the inwall of rain cover 3, and through the space blend stop and rain cover, discharge eventually through dust-discharging mouth 31, purify air and enter combustion chambers of internal combustion engines through interface 2 by air-strainer.The diameter of above-mentioned guiding bar, much smaller than the disengagement chamber diameter of rain cover, makes suction port dust exhaust port further away from each other, reduces secondary back probability.
Above-described specific embodiment; the purpose of this utility model, technological scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (4)
