Not only structural design is ingenious for above -mentioned urea solution device of maring, connects reliably, and convenient assembling, the maintenance of being convenient for is difficult for breaking down in the use.
Description
Technical field
The utility model is related to a kind of urea solution tank, and more particularly, to a kind of diesel engine selective catalysis transformation system is used for
The urea liquid filling apparatus of system.
Background technology
At present, serious atmosphere pollution has been supervened in the fast development of motor vehicle, presents region composite type feature.Perhaps
More metropolitan atmosphere pollution turns to coal smoke and the pollution of automotive composite type via coal-smoke pollution, and minority megalopolis is
Substantially show photochemical fog type (i.e. motor-vehicle tail-gas type) atmosphere pollution.Therefore, exhaust gas from diesel vehicle exhaust emission control skill
The research of art and its important and extremely urgent.
From the point of view of the development of commercial car, diesel engine is its major impetus.Typically I can be met using supercharging technology diesel vehicle
The emission request in stage, phase il employs charge inter cooling, and ii I-stage introduces electronic fuel injection technology, iv rank
Section needs to post-process exhaust in above-mentioned technical foundation.
Mainly there are two technology paths in the exhaust after treatment system of stage iv emission control：(1) started by optimization
Machine (internal purification technology, optimization oil spout, optimization burning etc.) reduces PM discharge+SCR selective catalysis reduction reactions reduces NOx rows
Put.(2) using EGR exhaust circulating technology reduce NOx emission+using particulate trap reduce PM discharge.It is more likely at present
Using the first scheme.
Urea solution tank is requisite vitals in SCR system, at present, the existing urea for SCR system
NaOH solution tank NaOH filling apparatus have the disadvantage that：
1) because Light-duty Vehicle space is little, while and require urea solution tank filling apparatus by vehicle body, existing filling apparatus without
Method realizes this kind of layout；
2) existing urea NaOH solution tank NaOH filling apparatus easily form residual urea crystallization at filler.
Disadvantages mentioned above has a strong impact on arrangement of the urea solution tank in Light-duty Vehicle, becomes those skilled in the art anxious to be resolved
A problem.
Utility model content
The purpose of this utility model is to provide a kind of urea liquid filling apparatus, and it has simple structure, is easily installed
With safeguard and the characteristics of filler is not in urea crystals, to solve prior art in above-mentioned asking of existing of urea solution tank
Topic.
It is that, up to this purpose, the utility model is employed the following technical solutions：
A kind of urea liquid filling apparatus, it includes urea tank cover, transitional connection pipe, filler seat and screen pack, wherein,
The urea tank cover is arranged at the upper opening of the transitional connection pipe, and the other end of the transitional connection pipe is connected to described
In filler seat, the screen pack is installed on the bottom of the filler seat, and inner tube is provided with the transitional connection pipe, described
It is less than at the upper opening of the transitional connection pipe at the upper opening of inner tube, on the tube wall of said inner tube refluxing opening is offered,
Sealing between the bottom of said inner tube and the transitional connection pipe is provided with several magnet steel.
Especially, some air slots are offered along its short transverse on the inwall of said inner tube.
Especially, grab is provided with outside the transitional connection pipe, the correspondence grab is offered on the filler seat
Draw-in groove, the transitional connection pipe is connected on the filler seat by grab and draw-in groove.
Especially, sealed by " O " type sealing ring between the transitional connection pipe and the filler seat.
Especially, the screen pack is installed on the filler seat by helicitic texture.
The beneficial effects of the utility model are that compared with prior art the urea liquid filling apparatus have following excellent
Point：
1) transitional connection pipe and filler seat are connected using buckling apparatus, and smart structural design, connection is reliable, assembling side
Just, it is easy to maintenance；
2) refluxing opening is offered in inner tube, when there is the urea liquid of residual in filler pipe, urea liquid can be by backflow
Mouth stays back tank interior, prevents having urea crystals in filler pipe；
3) magnet ring is designed using enclosed construction, magnet ring is wrapped in transitional connection pipe, it is to avoid magnet ring and urea liquid
Directly contact brings corrosion magnet ring phenomenon；
4) offer air slot in inner tube, profile of tooth air slot structure design, during automatic filling urea liquid, sometimes because
Filling speed is too fast, and air pressure has little time release in tank, and urea can be caused to overflow from filler, has profile of tooth air slot just completely may be used
To avoid the generation of this phenomenon.
