Description
Technical field
The utility model relates to the improvement of air-strainer technology, specifically refers to a kind of oil bath air cleaner with the benzvalene form rough filtering device, belongs to the air-strainer technical field.
Background technique
The effect of air-strainer is with air-filtering, mixes to form mixed gas mixed gas igniting combustion and doing work with atomized fuel again.Fig. 1 and Fig. 2 are existing a kind of air filtering device structure schematic representation, on scheming, can find out, it mainly comprises sky lower cover 1, metal filtering core 3, sponge filter core 4, empty loam cake 2, empty case member 5, inlet plate 23 and center tracheae 6, metal filtering core 3 and sponge filter core 4 are installed in the sky lower cover 1 by fitting seat separately, again empty loam cake 2 lower ends are docked with empty lower cover 1 upper end and close up the cylindrical structure that forms a sealing and by clip 7 fastenings, closed position is provided with seal ring 17, prevents air leakage.Central position at empty loam cake upper end end face and sponge filter core and metal filtering core is respectively equipped with a circular hole, and center tracheae 6 extend in the sky lower cover 1 by above-mentioned circular hole successively.Empty lower cover 1 bottom forms oil bath 8 and is used for splendid attire machine oil, and the oiling scale 9 in that bottom centre is provided with a ring-type can not surpass the height of ring-type oiling scale in order to show machine oil.Scale 9 walls that refuel are provided with some through holes 10, communicate so that refuel the inside and outside machine oil of scale, and purpose is oil bath center organic oil also when guaranteeing machine tip, is unlikely to flow on one side.Empty case member 5 and inlet plate 23 are installed in center tracheae 6 upper ends, are provided with some inlet holes at inlet plate, and gapped so that air can pass through between inlet plate and the empty loam cake upper end.
The principle of above-mentioned air-strainer filtered air is such: air is successively by the gap between inlet plate 23 and empty loam cake 2 upper ends, inlet hole on the inlet plate enters sky case member 5, enter central gas pipe 6 after being subjected to stopping of sky case member 5 to change direction, arrived the oil bath 8 of empty lower cover bottom by center tracheae 6, airborne most of dust is adsorbed by the machine oil in the oil bath, airborne remaining dust is being filtered behind metal filtering core 3 and sponge filter core 4 successively, thereby obtain clean air and by the flange 22 outlet discharges on empty loam cake 2 sides, enter next link.Enter in the sky loam cake for fear of air without the sponge filter core, between sponge filter core 4 and center tracheae 6, be provided with sealing gasket 18.
In said structure, the purpose that oil bath is set is exactly the adsorptive pressure that alleviates metal filtering core and sponge filter core, because if there is not the absorption of machine oil in the oil bath, metal filtering core and sponge filter core can be stopped up by dust very soon, thereby cause the machine cisco unity malfunction, need clean metal filter core and sponge filter core.Even but like this, if airborne dust is a lot, equally also bring pressure to oil bath, more the frequency of change engine oil will increase, not only cumbersome, and can not be in time more in the situation of change engine oil, the air-filtering effect can be affected, thereby bring a series of chain reaction, can affect equally the normal operation of machine.
The model utility content
For the prior art above shortcomings, the purpose of this utility model is to provide a kind of pressure that alleviates machine oil absorption dust in the oil bath, makes the air-strainer of air-filtering better effects if.
To achieve these goals, the technical solution adopted in the utility model is such:
Oil bath air cleaner, it mainly comprises sky lower cover, empty loam cake, metal filtering core, sponge filter core, empty case member and center tracheae, metal filtering core and sponge filter core are installed in the sky lower cover by fitting seat separately, and empty loam cake docks with empty lower cover and closes up the cylindrical structure that forms a sealing and pass through bindiny mechanism's stressed joint; Central position at empty loam cake upper end end face and sponge filter core and metal filtering core is respectively equipped with a circular hole, and the center tracheae extend in the sky lower cover by above-mentioned circular hole successively and is positioned at the oil bath top of sky lower cover bottom; It is characterized in that: cover at sky and be provided with an air inlet cylinder, the air inlet cylinder is provided with some inlet holes; Be provided with closing in conically shaped up in the air inlet cylinder, equal angles is provided with some coarse filtration blades on the endless belt between conically shaped and the center tracheae, and all coarse filtration blades are obliquely installed the formation helix structure in the same direction; Connect by annular connecting plate between air inlet cylinder and the conically shaped, the inlet hole on the air inlet cylinder is positioned under the annular connecting plate, is provided with the dust-discharging mouth at annular connecting plate; By empty case member end face the air inlet cylinder is pressed on the sky when empty case member is connected with the center tracheae and covers.
Described air inlet cylinder lower end surface is provided with some profile of tooth breach, and this profile of tooth breach consists of described inlet hole.
Described empty loam cake and empty lower cover closed position are provided with seal ring; Between sponge filter core and center tracheae, be provided with sealing gasket.
The Placement of described empty case member and center tracheae is: be provided with a horizontal stroke side in tracheae upper-end surface, center along diametric(al), one screw rod that is positioned at central gas tubular axis line is set in the horizontal stroke side, and empty case member is enclosed within on the screw rod and by nut check empty case member end face is pressed on the air inlet cylinder.
After the utility model air enters the air inlet cylinder, owing to produce eddy current when the helix structure of coarse filtration blade makes air enter conically shaped by the coarse filtration blade, add the cone structure of conically shaped, thereby produce centrifugal force and make air and airborne most of dust separation, dust is because centrifugal force is thrown out of in the laying dust groove between air inlet cylinder and the conically shaped, and discharges from this air-strainer by the suction port on the dust-discharging mouth on the annular connecting plate and the air inlet cylinder.Air then back enters the center tracheae and goes forward side by side into oil bath the absorption of residual part dust, by metal filtering core and sponge filter core dust residual in the air is filtered successively again, thereby be relatively cleaner air by making the air of going out from flange after repeatedly processing.
Compared to existing technology, the utlity model has following beneficial effect:
1, air is by the preliminary filtration of coarse filtration blade and conically shaped, and the dust in the air more than 80% is got rid of to the laying dust groove between air inlet cylinder and the conically shaped by centrifugal force, discharges by the dedusting mouth again.By this preliminary filtration, greatly alleviated the filtering burden of follow-up filtering section, improved the whole filtering effect of this air filter, prolonged maintenance period.
Although 2 air inlets and dedusting all will be by the suction ports on the air inlet cylinder, this product on intake resistance without impact, with improve before the intake resistance of air-strainer consistent.
