Definitions

  • an electric heater is installed in the storage tank, inside a cup open at the bottom.
  • the heat output by the heater is used first to thaw the content of the cup.
  • a suction lance likewise of heated design, the liquid thawed around the heater is extracted via the suction lance and introduced into the exhaust gas.
  • the conveying means regulates a constant system pressure via the pump motor rotational speed, the pressure sensor and a return flow throttle. The return flow quantity is generally led back into the heating cup again via a return line.
  • the tank interior has to be aerated and ventilated with respect to the surroundings.
  • the air space in the cup-shaped container via a hose line into the air space of the storage tank for receiving the reducing medium.
  • the air space of the storage tank is connected to the surroundings via a ventilation element, by which means pressure equalization can be carried out into the surroundings, both in the air space in the cup and the air space above the tank, taking the hose line into account.
  • the ventilation path is accordingly established from the underside of the tank via an air path, established during the heating of the return line, between the peripheral surface of the return and the inner side of the reducing agent, present in frozen form, into the upper air space in the cup, from there via the ventilation line into the air space at the upper side of the tank beside the cup-shaped container, and from there via the ventilation element into the surroundings.
  • the ventilation line which extends from the air space in the upper region of the cup-shaped container into the air space of the storage tank, is preferably made of a reducing agent-resistant material such as EPDM or PA12 or the like.
  • the ventilation line is pushed onto appropriately formed, preferably injection molded on, spigots of plastic material, both on the lid of the cup-shaped container and on the tank lid, and fixed, for example, by means of a profiled extension (Christmas tree profile).
  • the storage tank can be implemented as an injection molding or the tank lid of the storage tank can be made of plastic material in the course of the injection molding process.
  • the connection just like the spigots for pushing on the ventilation line, can all be injection molded directly onto the upper side of the tank in one operation without any complicated finishing steps being needed.
  • the solution proposed according to the invention offers simplification of the design and therefore greater robustness with low manufacturing costs because of the omission of a number of parts. Furthermore, in the storage tank proposed by the invention, considerable simplification of the installation can be achieved because of the reduced number of components, and thus a considerable reduction in the manufacturing costs. In relation to fording-capable systems, only one hose connection is required, which likewise results in considerable simplification.
  • an air space which above the frozen content of a tank and an air space which above the frozen content of a cup which is introduced into the tank is aerated or ventilated into the surroundings via a separate ventilating means in each case.

  • the reducing agent 12 stored in the storage tank 10 begins to freeze and a solid ice phase 14 and a liquid phase 16 are established in the storage tank 10 .
  • freezing of the reducing agent supply 12 in the storage tank 10 takes place at outside temperatures between ⁇ 11° C. and ⁇ 40° C.
  • the storage tank 10 comprises a tank lid 18 and a tank bottom 20 and a cup-shaped container 22 introduced into the interior of the storage tank 10 at the upper side of the storage tank 10 .

  • FIG. 1 reveals that both the storage tank 10 and the cup-shaped container 22 are aerated and ventilated via a tank ventilating means 36 and a cup ventilating means 38 respectively.
  • a tank ventilating means 36 and a cup ventilating means 38 respectively.
  • this opening 40 is closed in the event of freezing, however, since the solid phase 14 of the reducing agent 12 expands by about 10% at the liquid/solid phase transition because of the expansion of the reducing agent.
  • the air space 48 is ventilated via the tank ventilating means 36 , while the air space 50 in the upper region of the cup-shaped container 22 , which is closed by the lid 32 , is aerated and ventilated separately with respect to the outside via the cup ventilating means 38 .
  • a ventilation element 42 which is generally formed in the manner of a tablet.
  • FIG. 2 shows an illustration of the fixing of the tablet-shaped ventilation element in the ventilation connector of the cup-shaped container according to the illustration in FIG. 1 .
  • the ventilation element 42 is placed against a collar 44 in the connector of the tank ventilating means 36 .
  • warm calking 46 may be provided, which engages under the lower flat side of the tablet-shaped ventilation element 42 and thus fixes the latter reliably underneath the opening of the connector of the cup ventilating means 38 .
  • the tablet-shaped ventilation element 42 is fixed underneath the cup ventilating means 38 via the warm calking 46 .
  • two separate ventilating means namely the tank ventilating means 36 and the cup ventilating means 38 , are illustrated.
  • FIG. 3 reveals a further design variant of the solution proposed in accordance with the invention.
  • the cup-shaped container 22 is located in the storage tank 10 for receiving the reducing agent supply 12 .
  • phase separation of the reducing agent supply 12 into the solid ice phase 14 and into the liquid phase 16 is established both within the storage tank 10 and within the cup-shaped container 22 .
  • the air spaces 48 and 50 already mentioned are produced. While the cup-like container 22 is closed by the lid 32 , the air space 48 of the tank is closed by the tank lid 18 .
  • the two air spaces 48 and 50 are separated from each other by a sealing point 68 , at which the solid ice phase 14 of the reducing agent supply 12 rests on the underside of the tank lid 18 , so that the two air spaces 48 and 50 are cut off from each other and no air exchange between the latter can take place.
  • a first connection 62 in the form of a spigot, which is used to receive a ventilation line 60 .
  • the ventilation line 60 extends from the first connection 62 on the upper side of the lid 32 which closes the cup-shaped container 22 to a second connection 64 which, for example, can be injection molded onto the upper side of the tank lid 18 in the form of a spigot.
  • the ventilation line 60 is preferably made of a reducing agent-resistant material, preferably from a flexible elastomer material or thermoplastic.
  • the air space 50 above the level 28 of reducing agent 12 in the cup-shaped container 22 is connected to the air space 48 in the storage tank 10 underneath the tank lid 18 , i.e. ventilated into the latter.
  • the air space 48 is assigned an aeration/ventilation line 72 , which is formed in the manner of a connector, on the upper side of the tank lid 18 , and closed via a spider's web screen 74 .
  • the aeration/ventilation line 72 comprises a ventilation element 42 formed in the manner of a tablet, which is fixed in and enclosed by the third spigot 70 and which is made of a water-repellent material exhibiting hydrophobic properties.
  • FIG. 3 reveals that, starting from the lower region within the cup-shaped container 22 , in which the heater 26 is located, the following air path 66 is established: because of the fact that the suction lance 24 which extends through the cup-shaped container 22 is a heatable suction lance, an air gap established as a result of heating is formed between the outer side of the heatable suction lance 24 and the solid ice phase 14 of the reducing agent supply 12 enclosing said suction lance 24 . Therefore, the liquid phase 16 which surrounds the heating element 26 and the air space 50 above the level 28 of the cup-shaped container 22 are connected to each other in a manner permitting pressure equalization.
  • the air space 50 is then connected to the air space 48 of the storage tank 10 underneath the tank lid 18 , so that common aeration and ventilation of both air spaces, i.e. of the air space 48 and also of the air space 50 , can take place via one and the same aeration/ventilation line 72 which, in the design variant according to FIG. 3 , is assigned to the storage tank 10 or the air space 48 of the latter.
  • the lid 32 with which the cup-shaped container 22 is closed is preferably made as a plastic injection molded component, so that, advantageously, both an opening for a return 52 and the first connection 62 can be injection molded thereon.
  • the lid 32 for closing the cup-shaped container 22 is fixed by means of a lid screw fixing 54 to an external thread 34 of the tank lid 18 , which, during fabrication of the storage tank 10 as a plastic injection molded component, can likewise be produced in a simple way.
  • Sealing of the ventilation line 60 after being pushed onto the first connection 62 and the second connection 64 of the tank lid 18 can be implemented, for example, by means of a Christmas tree profile of the first connection 62 and the second connection 64 , as illustrated in FIG. 4 .
  • the second connection 64 and also the third connection 70 which is used to receive the connector 72 for aeration and ventilation, can advantageously be injection molded onto said storage tank 10 , which has a beneficial influence on the manufacturing costs and permits a high degree of freedom with regard to the tank geometry of the storage tank 10 .
  • a fording-capable storage tank 10 by a hose of flexible material, for example plastic material, being connected to the third connection 70 of the aeration/ventilation line 72 on the upper side of the tank lid 18 and extending into a permanent air space, so that at all times ventilation of the air spaces 48 , 50 , which are connected to each other via the ventilation line 60 , into the permanent air space is ensured.
  • This possibility also exists in the design variant according to FIG. 1 , in that in each case plastic hoses are slipped onto the tank ventilating means 36 and the cup ventilating means 38 , and thus a fording-capable system is created.
  • a simplified structure of the storage tank 10 results, be it capable of fording, be it designed for a system not capable of fording.
  • the ventilation element of the cup ventilating means 38 should always be designed to be smaller than the ventilation element 42 of the tank ventilating means 36 or 72 , because of the installation space and of the volume to be ventilated.
