CO is produced as with lower hydrolysis2And NOx is reduced into free of contamination nitrogen and water as reducing agent by ammonia, ammonia.
Urea tank is essential important component in SCR system；It is used to hold urea liquid, currently, existing use
In SCR system when carrying out filling urea liquid manually, often makes urea liquid full of urea tank, cause urea tank without safety
Expansion space the problem of, there are some potential safety problemss.
Summary of the invention
The purpose of the present invention is to provide a kind of with the anti-urea tank for filling it up with function manually, to solve prior art urea
Tank there are problems that preventing filling it up with function when filling manually.
To achieve this purpose, the present invention adopts the following technical scheme:
It is a kind of with the anti-urea tank for filling it up with function manually comprising urea tank body is equipped with urine on the urea tank body
Plain filler component and ventilative valve module are equipped with cover assembly on the urea filler component, wherein the urea filling
The bottom of mouth component, which is equipped with, protrudes into the intracorporal liquid feeding mouth filter screen set of urea tank, and the ventilative valve module includes vent valve and connection
In vent valve bottom and the intracorporal gas-guide tube of urea tank is protruded into, the bottom of the gas-guide tube offers air hole, the liquid feeding mouth
It is set with except filter screen set and prevents filling it up with casing, described anti-one end for filling it up with casing is fixed on liquid feeding mouth filter screen set, and the other end is
Open end, the anti-open end for filling it up with casing is also complete while the intracorporal urea liquid of urea tank is totally submerged air hole
Full submergence.
Particularly, pressure release aperture is offered above the air hole on the gas-guide tube.
Particularly, the urea filler component inclination is fixed on the urea tank body.
Particularly, the urea filler component is fixed on the urea tank body by fixing screws and washer.
Particularly, the liquid feeding mouth filter screen set is fixedly connected on urea filler component by helicitic texture.
Particularly, described to prevent that fill it up with casing is fixedly connected on liquid feeding mouth filter screen set by helicitic texture.
Particularly, the urea filler component and ventilative valve module are installed on described with being each perpendicular to urea liquid liquid level
On urea tank body.
Beneficial effects of the present invention are, described compared with prior art to fill it up with the urea tank of function to urine manually with anti-
When plain tank carries out filling urea liquid manually, when urea liquid overflows filler, remind user that urea solution tank has added at this time
It is full, it need to stop filling, also there are enough safe expansion spaces in urea solution tank at this time.It is not only simple in structure, only in original
On the basis of urea solution tank filler assembly with minor modifications, it is integrated on filler assembly, and the whole series fill it up with function with anti-
The installation of the fill port systems of energy and required assembly space are remained unchanged with original state, can will greatly promote urea solution tank
Safety in utilization.
Detailed description of the invention
Fig. 1 is the structural schematic diagram with the anti-urea tank for filling it up with function manually that the specific embodiment of the invention provides；
Fig. 2 is the urea filler group with the anti-urea tank for filling it up with function manually that the specific embodiment of the invention provides
The assembling schematic diagram of part.
Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
It please refers to shown in Fig. 1 and Fig. 2, in the present embodiment, a kind of to fill it up with the urea tank of function manually include urea with anti-
Tank body 1, urea filler component 2 and ventilative valve module 3 are equipped on urea tank body 1, and urea filler component 2 passes through fixed spiral shell
Nail 4 and washer 5 are fixed on urea tank body 1, and cover assembly 6, urea filler component 2 are equipped on urea filler component 2
Bottom the liquid feeding mouth filter screen set 7 protruded into urea tank body 1 is installed by helicitic texture, be set with except liquid feeding mouth filter screen set 7
Have and prevent filling it up with casing 8, anti-one end for filling it up with casing 8 is fixedly connected on liquid feeding mouth filter screen set 7 by helicitic texture, and the other end is
Open end, liquid feeding mouth filter screen set 7 favour the liquid level setting of urea liquid 9.
Ventilative valve module 3 includes vent valve 30 and is connected to 30 bottom of vent valve and protrudes into the gas-guide tube in urea tank body 1
31, gas-guide tube 31 is arranged perpendicular to the liquid level of urea liquid 9, and the sustained height of 31 bottom of gas-guide tube is uniformly distributed, and there are four air holes
32, offer pressure release aperture 33 in the top of air hole 32 on gas-guide tube 31, gas-guide tube 31 and it is anti-fill it up with casing 8 have it is certain
Installation site relationship needs to meet and prevents filling it up with casing while the urea liquid 9 in urea tank body 1 is totally submerged air hole 32
8 open end is also completely submerged.
The above-mentioned working principle with the anti-urea tank for filling it up with function manually are as follows: when user fills urea liquid manually,
When the submergence of the liquid level of urea liquid 9 is anti-fills it up with casing 8, while liquid level also submerges the air hole 32 of ventilative valve module 3, is further continued for
When filling urea, the air in urea tank body 1 can not be quickly discharged, and pressure in urea tank body 1 is caused to increase, and continue to add
When infusing urea liquid, urea liquid will be overflowed from filler, be reminded user that urea solution tank has been filled it up at this time, need to be stopped filling,
To realize the anti-function of filling it up with manually of urea tank.At this point, in urea tank body 1 top can there are enough safe expansion spaces
10, the air in safe expansion space 10 can be discharged outside the tank slowly by pressure release aperture 33 by vent valve 30, greatly improve urine
The safety that plain NaOH solution tank NaOH uses.
The above embodiments only describe the basic principles and characteristics of the invention, and the invention is not restricted by the above cases,
Without departing from the spirit and scope, the invention also has various changes and changes, and these changes and changes are both fallen within
