Abstract
The utility model discloses a urea box with a controllable filling amount, which comprises a box body and a filling opening disposed on the box body. The urea box is further provided with an observing window used for operators to observe spill-over degree of urea solution in the box body and control the filling amount. By means of the observing window, the operators can observe conditions of the surface of filled liquid in the box body through the observing window, thereby enabling the operators to have an appropriate judge based on which to decide whether to fill or not and correctly learn when to stop filling during the filling process so as to avoid overfilling, and preserving enough expansion space for the urea solution to freeze with cold, effectively preventing the box body from being split and ensuring safety of usage.
Description
Technical field
The utility model relates to the urea box art, refers in particular to the controlled urea box of a kind of adding amount.
Background technique
Diesel engine is used widely having obtained in the higher thermal efficiency and the lower every profession and trade of toxic emission all over the world, but its higher discharged nitrous oxides is puzzlement people's a problem always.Since the nineties in 20th century,, promoted the continuous development of engine technology along with the continuous strictness of countries in the world to fuel oil (gas) motor car engine Abgasgesetz.At present, the technology path of realizing state's IV emission standard has the former processing of SCR(urea selective recall), EGR+DPF(exhaust gas recirculation+grain catcher), LNT(nitrogen oxygen adsorber), CRT(cyclic regeneration grain catcher) etc., wherein occupy an leading position with SCR catalytic reduction technology, domestic large-scale diesel engine producer of a few family also big more options this technology path, it is to utilize emission controls by improving combustion to reduce soot, utilizes the SCR system to reduce the method for NOX discharging then.
The aqueous solution of urea of commercial usefulness is called AdBlue, and it is nontoxic, clean, be difficult for catching fire, no explosion risk, and it is used for reducing discharged nitrous oxides with nitrogen oxide generation chemical reaction.Container as aqueous solution of urea is called urea box, urea box of the prior art all uses lighttight plastic cement material to make, the operator can't see through the height situation that casing is seen the filling liquid level, when urea box when adopting artificial filling, the operator can not get a suitable basis for estimation that stops to annotate, can not be accurately being held in when to stop filling in the filling process, thereby cause filling excessive easily, can cause storing in the casing too much urea liquid with this, urea liquid too much will make the expansion volume reducing of urea box, when urea liquid is met cold junction ice, the volume increase of can expanding, exist the risk that casing is burst, bring potential safety hazard to use.
The model utility content
In view of this, the utility model is at the disappearance of prior art existence, its main purpose provides the controlled urea box of a kind of adding amount, and it can effectively separate the problem that existing urea box operator in filling urea liquid process can't cause excessive filling through casing control urea liquid adding amount.
For achieving the above object, the utility model adopts following technological scheme:
The urea box that a kind of adding amount is controlled includes casing and the filler that is arranged on this casing, further is provided with to be used to observe the viewing window of the interior urea liquid spill-over degree of this casing with the control adding amount.
As a kind of preferred version, described filler includes base portion and neck, and the periphery of this base portion is connected with the box sealing formula, and this neck one on base portion is extended, and this neck is communicated with between the box house and the external world, and aforementioned viewing window is arranged on this base portion.
As a kind of preferred version, the periphery of described viewing window is connected with this base portion is sealed type jogged.
As a kind of preferred version, described base portion is obliquely installed in the top of casing lateral margin, and this viewing window is positioned at the other below of side of neck, and this viewing window is provided with the highest liquid level line.
As a kind of preferred version, described viewing window is rounded.
As a kind of preferred version, described viewing window is a transparent material.
The utility model compared with prior art has tangible advantage and beneficial effect, particularly, and as shown from the above technical solution:
One, by being provided with viewing window, see through the height situation that this viewing window operator can see filling liquid level in the casing, thereby make the operator obtain a suitable basis for estimation that stops to annotate, accurately being held in when to stop filling in the filling process, it is excessive to avoid annotating, meet cold junction ice for urea liquid and reserve enough expansion spaces, effectively stop the appearance that casing is bursting at the collision risk, guarantee the Security of using.
Two, by viewing window being arranged on the base portion of filler, the periphery of this viewing window is connected with base portion is sealed type jogged, makes this viewing window be installed in the lump on the casing with filler, and is simple in structure, and processing and manufacturing are also very convenient.
Three, by the other below of the side that viewing window is arranged at neck, and be provided with the highest liquid level line in viewing window, utilize this highest liquid level line to remind operator when liquid level arrives the highest liquid level line, should stop to annotate, be operator's providing convenience property of urea liquid of annotating.
For more clearly setting forth structure characteristic of the present utility model and effect, come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment.

Embodiment:
Please refer to illustrated in figures 1 and 2ly, the concrete structure that it has demonstrated the preferred embodiment of the utility model includes casing 10, filler 20 and viewing window 30.
On this casing 10 urea level sensor 40 is installed, the concrete structure of this urea level sensor 40 and working principle are not described in detail in this concrete structure and working principle to urea level sensor 40 for existing mature technology.
This filler 20 is arranged on the casing 10, by this filler 20 urea liquid is filled in the casing 10, this filler 20 includes base portion 21 and neck 22, this base portion 21 is rounded, base portion 21 is obliquely installed in the top of casing 10 lateral margin, and the periphery of base portion 21 is connected with the wall sealed type of casing 10; This neck 22 one on this base portion 21 is extended, and this neck 22 is communicated with between casing 10 inside and the external world.
This viewing window 30 is used to observe the spill-over degree of urea liquid in this casing 10, so that control adding amount, this viewing window 30 is arranged on the base portion 21 of aforementioned filler 20, the periphery of this viewing window 30 and these 21 sealed type jogged connections of base portion, and viewing window 30 is positioned at the other below of side of aforementioned neck 22, this viewing window 30 is rounded, and it is a transparent material.Be positioned at viewing window in the aforementioned casing 10 and be the nominal volume space below 30, be positioned at viewing window and be the expansion volume space more than 30, simultaneously, this viewing window 30 is provided with the highest liquid level line 31, this the highest liquid level line 31 is used to remind the operator to work as when liquid level arrives the highest liquid level line 31 should stop filling, reserves enough expansion spaces to freeze to urea liquid.Of particular note, this viewing window 30 also can be arranged on the casing 10, and the position of its setting is not limited on the filler 20, only need utilize viewing window 30 can observe the spill-over degree of urea liquids in the casing 10 so that the operator controls adding amount gets final product.
