Description
Technical field
The utility model relates to a kind of deaerator, especially relates to the improvement of the deaerator structure that a kind of oil gas that crankcase is discharged separates.
Background technique
Contain organic oil in the mixed gas of the crankcase scavenged of internal-combustion engine, in reclaiming combustion process, can be adsorbed on each parts of internal-combustion engine, form carbon deposit, reduce the service behaviour of internal-combustion engine, quicken the waste of internal-combustion engine abrasion and machine oil, reduce engine operation efficient, shorten the life-span, discharge more harmful gas befouling environment simultaneously.So adopt the machine oil that reclaims in the firing unit separation oil and gas, so there is the people to design the gas and oil separating plant (patent No.: 95218800.7), at sealing shell a helical separator tube is set, the mixed gas that crankcase is discharged is mapped on the separator tube, machine oil just apposition temporarily flows out on separator tube and along separator tube, though this invention is simple in structure, can only separate and drip shape machine oil, vaporific machine oil is not played good separating effect; Also the someone designs a kind of deaerator (patent No.: 97202028.4) last lower box is arranged of diesel engine, mandrel and filter disc are formed, spacer is arranged between filter disc and adopted filter screen device, this model utility was improved to former technology, mainly be that filtration by filter screen comes separation oil and gas, but exist filter disc or filter screen to stop up easily equally, under the effect of internal-combustion engine continuous negative pressure, can not regulate pressure with the balance crankcase, the adsorption force of vaporific machine oil on filter disc or filter screen is little, just can not separate vaporific machine oil well.Someone also design other as the labyrinth, gas and oil separating plants such as negative pressure control, but all exist can not regulate with the balance crankcase pressure with can not separate technical problems such as vaporific machine oil fully efficiently.
Summary of the invention
The utility model mainly be solve existing in prior technology can not regulate with the balance crankcase pressure with can not separate technical problem such as vaporific machine oil fully efficiently, provide a kind of and can regulate a kind of balanced type deaerator that can separate vaporific machine oil with the balance crankcase pressure again fully efficiently.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of balanced type deaerator, casing, case lid are arranged, suction port and air outlet are located at respectively on casing and the case lid, filter screen I is located between suction port and the air outlet, casing is divided into cavity and filter rear chamber before the filter, it is characterized in that being provided with an air jet at least in the filter rear chamber of described balanced type deaerator.Cavity is meant the moving certain space of fuel feeding air-flow between suction port and the filter screen I before the filter, the filter rear chamber is meant the moving certain space of fuel feeding air-flow between air outlet and the filter screen I, cavity and filter rear chamber can be the certain spaces of cylindric, circular, tubulose or form such as slot on casing or case lid wall before the filter, the air that enters by air jet can be regulated and the continuous negative pressure effect of balance gas handling system, reduce the negative pressure of filter rear chamber, thereby strengthen the adsorption force of filter screen I greatly, make that filter screen I is more abundant to separate vaporific machine oil efficiently vaporific machine oil.
As preferably, be provided with an air jet in the filter rear chamber, the cross-section area of air jet is 4-50mm

As preferably, cavity is provided with oil deflector I and oil deflector II before the filter of described balanced type deaerator;
As preferably, filter preceding cavity and be provided with oil deflector I and oil deflector II, oil deflector I and the thick 0.2-2mm of oil deflector II, high 50-150mm.Because the effect of two oil deflectors has changed the glide path of oil gas, just filtered most of shape machine oil that drips, improved filter efficiency.
As preferably, be provided with a thick 0.2-2mm in the filter rear chamber, high 5-50mm oil deflector III, oil deflector III has certain altitude, and machine oil just can not be inhaled in the air guide sleeve and enters into the air outlet from blowhole.
As preferably, the inlet end of air jet connects an air passageways, is provided with filter screen II between the air inlet of the outer end of air jet and air passageways.Filter screen II can prevent that dust from entering the filter rear chamber by air jet.
As preferably, filter external casing or the case lid wall of ante-chamber and be provided with a hummer, the outer sympathetic response cover (13) that is provided with of hummer (12).Hummer is provided with wind ring sheet, and when the pressure of cavity before the filter surpassed safety value, hummer was just opened protective function, and the effect of sympathetic response cover is to make the sound of hummer become louder, plays the warning effect, so that in time safeguard.
As preferably, the exhaust outlet of hummer is connected with air passageways.Prevent from directly to be discharged into the air, enter cylinder combustion once more, reach the effect of more environmental protection but collect the oil gas that comes out from hummer by air passageways from the oil gas that hummer comes out.
As preferably, connect an air valve in the inlet end or the outlet side of air jet.The cross section of air valve can be circular, oval, square etc., but air valve can be constant cross-section or transfer cross section.
Therefore, the utlity model has compactness rational in infrastructure, design optimization can be regulated and can fully effectively separate characteristics such as vaporific machine oil with the balance crankcase pressure again.
