Description
Technical field
The present invention relates to a kind of agitating device, and in particular to a kind of urea for vehicle agitating device.
Background technology
Urea for vehicle is generally used in diesel engine, is a kind of use in SCR (SCR) technology
Liquid, its constituent is 32.5% high-purity urea and 67.5% deionized water, the purpose used are to reduce diesel oil
The nitrogen oxides pollution thing of machine discharge.The concentration of urea for vehicle has strict requirements, it is therefore desirable to which well mixed, mixing is uneven
Urea for vehicle in containing the urea block and bulk impurity that are not completely dissolved, can not only influence the clean-up effect of urea for vehicle,
And easily cause the blocking of vehicle pipeline and nozzle.Meanwhile existing urea for vehicle stirring technique can not be according to molten in stirred tank
The amount of liquid adjusts the height of agitator, and certain part solution is not stirred sufficiently in stirred tank, and this also result in the car of production
Uneven phenomenon is mixed with urea.
Utility model content
For the deficiency in the presence of prior art, the utility model provides a kind of urea for vehicle agitating device, and it has
Have simple in construction and the advantages of urea liquid can be sufficiently stirred.
To achieve the above object, the utility model employs following technical scheme：
A kind of urea for vehicle agitating device, including stirred tank, the stirred tank is interior to be provided with agitator and agitating shaft, described to stir
Mix device and the agitating shaft is detachably connected, the blade of the agitator is screw blade, and the stirred tank upper end is provided with
Deionized water entrance, urea crystal entrance and motor, the motor and the stirring axis connection, the stirred tank lower end sets urea
Outlet conduit and reflux line, the port of export of the reflux line are connected in the upper portion side wall of stirred tank, the urea outlet
Pipeline is provided with the first valve, and the reflux line is provided with water pump and the second valve.
Compared to prior art, the present invention has the advantages that：The screw blade stirring that the utility model uses
Area is bigger than common blade mixing area, and urea liquid can be back in stirred tank by reflux line and repeatedly be stirred, together
When agitator can according in stirred tank solution amount adjust mixing position, ensure production urea for vehicle be sufficiently mixed uniformly.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of agitating shaft in the utility model；
Fig. 3 is the structural representation of agitator in the utility model.
Embodiment
With reference to embodiment and Figure of description, the utility model is described in further detail, but this practicality is new
The embodiment not limited to this of type.
As shown in Figures 1 to 3, a kind of urea for vehicle agitating device provided by the utility model, including stirred tank 4, it is described to stir
Mix in kettle 4 and be provided with agitator 7 and agitating shaft 5, the agitator 7 and the agitating shaft 5 are detachably connected, the agitator 7
Blade be screw blade, the upper end of stirred tank 4 is provided with deionized water entrance 1, urea crystal entrance 3 and motor 2, described
Motor 2 is connected with the agitating shaft 5, and the lower end of stirred tank 4 sets urea outlet conduit 11 and reflux line 12, the return duct
The port of export in road 12 is connected in the upper portion side wall of stirred tank 4, and the urea outlet conduit 11 is provided with the first valve 9, described
Reflux line 12 is provided with the valve 10 of water pump 8 and second.
The number of turns of the screw blade is at least 3 circles, when the quantity of only stirring vane is enough, just can guarantee that urea is molten
Liquid stirring is uniform enough.
The agitator 7 is connected with agitating shaft 5 by screw 6, and axially aligned on the agitating shaft is provided with
Several mounting holes, for the ease of position of the regulation agitator in stirred tank, to improve the stirring efficiency to urea liquid, lead to
Cross and set multiple mounting holes to be achieved.
First valve and the second valve are the electrical ball valve of computer control.
Operation principle of the present utility model is that deionized water is added in stirred tank 4 by deionized water entrance 1, will be urinated
After cellulose crystal is added in stirred tank 4 by urea crystal entrance 3, agitator 7 is adjusted according to the liquid level of solution in stirred tank
Position, and be fixedly connected by screw 6 with agitating shaft 5, starting motor can be stirred, and pass through computer control while stirring
Make the second valve 10 to open, while open water pump 8, the urea liquid in stirred tank is pumped into stirred tank 4 by reflux line 12
Repeatedly stirred, be so sufficiently mixed uniform purpose to reach urine.
After the completion of stirring, motor 2, the valve 10 of water pump 8 and second are closed, opens the first valve 9, the urea to stir is molten
Liquid is flowed out by urea outlet conduit 11.
Finally illustrate, above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent substitution, without departing from the objective and model of technical solutions of the utility model
Enclose, it all should cover among right of the present utility model.
