Description
Technical field
The utility model belongs to the connection structure between one kind novel crankcase bleed pipe and air filter escape pipe, is related to one
The novel crankcase bleed pipe anti-frozen structure of kind can fall to exhale the water in crankcase case ventilation duct by the filter element filtering that absorbs water
Vapour is solved the problems, such as in extremely cold area ice blockage.
Background technique
The mixed gas in crankcase is scurried out into atmosphere pollution environment in order to prevent, can use engine crankcase
Ventilation duct is reintroduced back to engine after filtering mixed gas and burns.General crankcase bleed pipe and air filter escape pipe connect
Logical, mixed gas enters air filter escape pipe through ventilation duct in crankcase, after crossing with low temperature cleaned air easily tube wall it is cooling,
Icing results in blockage, and then leads in crankcase that air pressure is excessively high, destroys oil sealing, and mixed gas is caused to leak.
For the problem that crankcase bleed pipe ice blocks up, it is mainly the following solution at present:
1, arrangement heat-preservation cotton is surveyed in engine beautification the cover, or wraps up thermal insulation material on the outside of crankcase bleed pipe.This
Kind method implementation is easy to operate, but can introduce the excessively high heat management problems of temperature in enging cabin, simultaneously because arrangement space, material
Expect the limitation such as heat preservation property, it is practical that the anti-freeze effect of crankcase bleed pipe is extremely limited.
2, electric control heating arrangement is used in crankcase bleed pipe and air filter escape pipe junction.This method controls letter
Just, but higher cost needs additionally to increase control harness folk prescription.
3, antifreeze liquid-collecting box is used in crankcase bleed pipe and air filter escape pipe junction.This method requires arrangement
Height, long-term accumulation oil liquid, ice cube are not easy to be discharged in liquid-collecting box, and internal structure is complicated, switching die joint is more, cause in part feelings
The stifled situation of ice is still easily formed under condition.
Utility model content
The utility model is in view of the problems of the existing technology and insufficient, provides a kind of novel crankcase bleed pipe anti-caking
Ice structure fundamentally purges the steam inside crankcase bleed pipe, to solve crankcase bleed pipe and steam entrance
Cleaned air blockage air throttle destroys booster.
The utility model is to solve above-mentioned technical problem by following technical proposals:
The utility model provides a kind of novel crankcase bleed pipe anti-frozen structure, it is characterized in that comprising mainstream
Road pipeline, one end of the sprue pipeline is connect with crankcase bleed pipe, the other end and air filter escape pipe connect, the mainstream
Road pipeline is straightway cylindrical body and inner cavity is smooth, and the sprue channel interior is absorb water ventilative filter core and resistance screen interval
It is uniformly embedded in pipe, the bottom of the sprue pipeline is welded with liquid accumulating box, and the lower end for absorbing water ventilative filter core stretches to
In liquid accumulating box, the bottom of the liquid accumulating box is provided with drain valve.
Preferably, the sprue pipeline uses plastics.
Preferably, the connecting pin of the sprue pipeline connecting with crankcase bleed pipe is provided with anticreep boss.
On the basis of common knowledge of the art, above-mentioned each optimum condition, can any combination to get the utility model respectively compared with
Good example.
The positive effect of the utility model is:
The utility model can reduce sprue inner burr overlap and cause risk of icing, while low using resistance screen heating
Warm mixed gas, cold and hot cross to form droplet and adsorbed by water suction filter core, liquid accumulating box is then discharged into, through draining after liquid accumulating box water is full
Valve discharge；It is stifled that the program fundamentally solves the problems, such as crankcase bleed pipe ice, while it is tubular to avoid steam from entering cleaned air
At ice blockage air throttle or destroy booster；Structure is simple, easy to accomplish, convenient for disassembly and assembly, at low cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the crankcase bleed pipe anti-frozen structure of the utility model preferred embodiment.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, those of ordinary skill in the art's every other embodiment obtained without making creative work, all belongs to
In the range of the utility model protection.
As shown in Figure 1, the present embodiment provides a kind of novel crankcase bleed pipe anti-frozen structures comprising mainstream deferent
Road 1, one end of the sprue pipeline 1 is connect with crankcase bleed pipe, the other end and air filter escape pipe connect, the sprue
Pipeline 1 is straightway cylindrical body and inner cavity is smooth, is absorbed water between ventilative filter core 2 and resistance screen 3 inside the sprue pipeline 1
It is embedded in pipe every uniformly, the bottom of the sprue pipeline 1 is welded with liquid accumulating box 4, and the lower end for absorbing water ventilative filter core 2 is stretched
Enter to liquid accumulating box 4, the bottom of the liquid accumulating box 4 is provided with drain valve 5.
Crankcase bleed pipe mixed gas sprue is straightway cylindrical body, and the smooth connectionless die parting line in inner cavity can drop
Risk of icing caused by low point of mould overlap.Low-temperature mixed gas is through 3 heat temperature raising of resistance screen, cold and hot friendship in sprue pipeline 1
Remittance forms steam and is adsorbed by the ventilative filter core 2 of water suction.When the ventilative filter core 2 that absorbs water absorbs water very much, internal moisture is due to gravity
It accumulates in lower part liquid accumulating box 4.After the accumulation of 4 internal water of liquid accumulating box is slow, water is discharged through drain valve 5.
Anticreep boss is designed in sprue pipeline 1 and crankcase bleed pipe connecting pin, and guarantee is connected firmly and sealing performance, into
One step, clip can be increased and fastened.
1 overall structure of sprue pipeline is simple, can use plastic injection welding processing.
Although the foregoing describe specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
These are merely examples, and the protection scope of the utility model is defined by the appended claims.Those skilled in the art
Member can make numerous variations or be repaired to these embodiments under the premise of without departing substantially from the principles of the present invention and essence
Change, but these change and modification each fall within the protection scope of the utility model.
