Description

Integrated form urea tank
Technical field
Field of power machinery is the utility model is related to, more particularly to a kind of integrated form urea tank.
Background technology
SCR spraying systems are used in diesel engine post-processing system, the system for eliminating exhaust contaminant NOx.SCR injections system The included part of system has:Urea tank, antifreeze liquid electromagnetic valve, air cleaner, metering ejector pump, DCU components, nozzle and connection Pipeline.The system by the compressed air by air cleaner cleaning, utilizes anti-icing fluid by controlling metering ejector pump by DCU Magnetic valve leads to the preheated urea liquid for the being contained in urea tank mixing of anti-icing fluid, measures be ejected into mixing through nozzle according to actual needs In device, reduction reaction generation nitrogen and water occurs with NOx.
The effect of urea tank is to contain urea liquid, integrates urea sensor, urea level, temperature, density are supervised Control.
Existing urea tank technical scheme (such as Fig. 1):Urea tank is installed separately with antifreeze liquid electromagnetic valve 2, passes through antifreeze liquid pipe Connection, urea cleaner 3 are arranged on inside urea tank.The shortcomings that existing urea tank scheme:1st, urea tank and antifreeze liquid electromagnetic valve 2 Need to install respectively, between also need to that a connecting tube is installed, installation procedure is complicated, and time-consuming.2nd, the dismounting of urea cleaner 3 is tired Difficulty, need that (such as Fig. 2) could be changed the dismounting completely of urea sensor 6.Time-consuming, required big with changing space.During replacing, urea It is completely exposed outside with urea sensor 6 inside tank, easily causes urea tank internal contamination.
The information for being disclosed in the background section is merely intended to increase the understanding to general background of the present utility model, and It is not construed as recognizing or implies that the information structure has been existing well known to persons skilled in the art in any form Technology.
Utility model content
The purpose of this utility model is to provide a kind of integrated form urea tank, integration degree height, energy Fast Installation urea Cleaner and anti-icing fluid cleaner, and safeguard that replacing is convenient, system cost is low.
To achieve the above object, the utility model provides a kind of integrated form urea tank, including urea tank body and urea Sensor, it is located at the top of urea tank body to urea sensor, and urea sensor includes urea outlet and anti-icing fluid import, Integrated form urea tank includes:Antifreeze liquid electromagnetic valve and anti-icing fluid cleaner.Antifreeze liquid electromagnetic valve is integrated in urea tank body Top, to control anti-icing fluid to urea progress ice thaw;And anti-icing fluid cleaner is arranged on urea sensor, and with Anti-icing fluid import connects, to filter the impurity of anti-icing fluid.
Preferably, in above-mentioned technical proposal, integrated form urea tank also includes urea cleaner, and it is arranged at anti-icing fluid filtering The side of device, and export and connect with urea, to the impurity of filter urea solution.
Compared with prior art, the utility model has the advantages that:Integrated form urea tank of the present utility model, collection High, energy Fast Installation urea cleaner and anti-icing fluid cleaner into change degree, and safeguard that replacing is convenient, system cost is low.
Brief description of the drawings

Embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality New protection domain is not limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members Part or other parts.
As shown in figure 3, according to a kind of integrated form urea tank of the utility model embodiment, including urea tank body 1 and urea sensor 6, urea sensor 6 is located at the top of integrated form urea tank, and urea sensor 6 include urea export and Anti-icing fluid import, integrated form urea tank include:Antifreeze liquid electromagnetic valve 2 and anti-icing fluid cleaner 4.Antifreeze liquid electromagnetic valve 2 is integrated in The top of urea tank body 1, to control anti-icing fluid to urea progress ice thaw.And anti-icing fluid cleaner 4 is arranged at urine On plain sensor 6, and it is connected with anti-icing fluid import, to filter the impurity of anti-icing fluid.
Preferably, integrated form urea tank also includes urea cleaner 3, and it is arranged at the side of anti-icing fluid cleaner 4, and with Urea outlet connection, to the impurity of filter urea solution.
Preferably, anti-icing fluid cleaner includes anti-icing fluid filter body, filter core 7 and closure 8, and filter core 7 is arranged at anti- Freeze inside liquid filter body, filter core 7 can be sealed in by closure 8 in anti-icing fluid filter body, maintains easily replacing Filter core 7.
Preferably, urea cleaner 3 includes urea filter body, filter core 7 and closure 8, and filter core 7 is arranged at urea filter Clear device body interior, can be sealed in filter core 7 in urea filter body by closure 8, maintains easily and changes filter core 7.
In a word, integrated form urea tank of the present utility model, integrates antifreeze liquid electromagnetic valve, install convenient, and integration degree carries Height, mounting bracket and the space of antifreeze liquid electromagnetic valve can be reduced, system cost reduces, volume reduces;Urea will be placed on originally Urea cleaner inside tank is changed to urea outlet, facilitates the replacing of urea cleaner, saves and changes space, shortens urea tank Maintenance time;Increase anti-icing fluid cleaner in anti-icing fluid import, can effectively protect antifreeze liquid pipeline and anti-icing fluid inside urea tank Magnetic valve, convenient disassembly.
