Description
Technical field
The utility model belongs to urea for vehicle technical field, more particularly to a kind of filter for urea liquid.
Background technology
In urea for vehicle solution manufacturing process, derivative contracting triuret can be generated, is in colloidal under contracting triuret low temperature, makes
There is low temperature gonorrhoea phenomenon in urea liquid.Contracting triuret not only have impact on the transparency of urea liquid, more damage urea product and system
Make the image of business.In urea liquid manufacturing process, contracting triuret dissolution time length, and need prolonged stirring heat absorption or add
Temperature, influence the efficiency of urea production.Later stage, contracting triuret was also easy to cause the urine of SCR exhaust systems during the use of urea
The obstruction of plain solution filter core.
The content of the invention
For disadvantages described above, technical problem to be solved in the utility model is:A kind of mistake for urea liquid is provided
Device is filtered, the filter for being used for urea liquid can remove the colloidal impurity in urea liquid, solve urea liquid low temperature
The problem of gonorrhoea, the transparency of urea liquid is improved, and it is excellent with simple in construction, operation and maintenance convenience, good impurity removing effect etc.
Point.
In order to solve the above technical problems, the technical solution of the utility model is：
A kind of filter for urea liquid, including tank body and the chimney filter installed in the tank interior, the filter
The tube wall of pipe is provided with multiple filter openings；The tank body is provided with entrance, outlet, backwash mouth and impurity removal port, the entrance and removes
Intracavity inter-connection of the miscellaneous mouth with the tank body, intracavity inter-connection of the outlet and backwash mouth with the chimney filter.
As an improvement the porch is provided with the first valve, the exit is provided with the second valve；It is described anti-
3rd valve is installed, the impurity-removing port position is provided with the 4th valve at rinse mouth.
As an improvement the chimney filter be provided with it is multiple, multiple chimney filters be arranged in parallel.
As an improvement multiple filter openings are evenly equipped with the tube wall of the chimney filter.
As an improvement the chimney filter is Filter film type chimney filter.
As an improvement the chimney filter is vertically arranged, the entrance is located at the upper end of the tank body, the outlet and institute
State the lower end that impurity removal port is respectively positioned on the tank body.
Above-mentioned technical proposal is employed, the beneficial effects of the utility model are：
A kind of filter for urea liquid of the present utility model includes tank body and chimney filter.First is first opened during use
Valve and the second valve, close the 3rd valve and the 4th valve.Urea liquid enters in tank body through entrance, and urea liquid passes through filter
Hole enters inside chimney filter, and the colloidal impurity of wherein macromolecular is blocked in outside chimney filter, and the urea liquid after filtering flows through outlet
Go out, complete the filtering to urea liquid.After the filter uses a period of time, the colloidal impurity of macromolecular can block filter opening,
Filter efficiency is reduced, now closes the first valve and the second valve, opens the 3rd valve and the 4th valve.Using backwash mouth to
Air is blown into chimney filter, the air with pressure will adsorb colloidal impurity on filter opening and blow off filter opening.Now close the 3rd valve
Door, the first valve is opened, input urea liquid from entrance, colloidal impurity can discharge from impurity removal port, can conveniently realize the dress
That puts is free of cleaning.The filter is free of cleaning using pressure-air blowback realization device, and it is molten that air dielectric does not interfere with urea
The concentration of liquid, it ensure that the quality of urea liquid after filtering.
Due to chimney filter be provided with it is multigroup, the filter efficiency of the filter can be improved.
In summary, a kind of filter for urea liquid of the present utility model, it is molten urea can rapidly to be removed
Colloidal impurity in liquid, solve the problems, such as urea liquid low temperature gonorrhoea, improve the transparency of urea liquid, and with structure letter
Single, operation and maintenance is convenient, the advantages that good impurity removing effect.
Brief description of the drawings
Fig. 1 is a kind of structural representation of filter embodiment for urea liquid of the present utility model；
Wherein：1- tank bodies, 11- entrances, 12- outlets, 13- backwash mouths, 14- impurity removal ports, the valves of 15- first, 16- second
