Definitions
- the invention relates to a delivery device for an aqueous fluff solution in a motor vehicle, with a tank, with a filter element and with a pump, the aqueous fluff solution being conveyable by means of the pump from the tank through the filter element into a suction line, the filter element containing a filter material and has a frame for receiving the filter material.
- ammonia NFI3
- ammonia is not usually kept as pure ammonia, since this can lead to problems, particularly in motor vehicles or other mobile applications. Rather, instead of storing the reducing agent itself often Reducing agent precursor stored and carried.
- a reducing agent precursor is understood to mean, in particular, a substance which splits off the reducing agent or can be chemically converted into the reducing agent.
- ammonia urea is a reducing agent precursor.
- the aqueous ammonia solution, the urea is carried in a tank and pumped into the exhaust tract in precisely metered quantities using a suitable pumping device.
- the conveying device regularly has, among other things, a pump for conveying the fluid, one or more filters for cleaning the fluid, optionally heating devices for thawing the fluid and a control device for processing internal and external data and for controlling the pump, the heating devices and others controllable components, such as the injector.
- a particular disadvantage of the devices in the prior art is that to date there have been no devices that ensure that when a filter is replaced, a product of sufficient quality and technical functionality is used, thereby ensuring the functionality of the entire device.
- An embodiment of the invention relates to a delivery device for an aqueous urea solution in a motor vehicle, with a tank, with a filter element and with a pump, wherein the aqueous urea solution by means of pump can be conveyed out of the tank through the filter element into a suction line, the filter element having a filter material and a frame for accommodating the filter material, the filter material being connected to the frame by means of a connecting element, the connecting element being part of the fluid conveying path from the tank via the filter element towards the pump.
- the aqueous flan substance solution which is referred to below as fluid, is conveyed via the pump from the tank to a consumer, such as an injector on the exhaust pipe.
- the fluid is conveyed from the tank through the filter material into a suction line to the pump, from where it is conveyed to the consumer.
- Special valves for controlling the flow of fluid and devices for degassing, in particular for removing air located in the lines, can be provided along the lines.
- the filter material can be formed, for example, by a net-like material, a porous material or an element which has a plurality of openings which allow the fluid to flow through, but prevent solids above a certain size from flowing through. Filter materials of this type are known in a variety of ways in the prior art.
- the filter material is characterized in particular by the fact that it is designed in such a way that the fluid from the tank can flow out of the tank into the suction line only over a defined cross section.
- the filter material can, for example, be designed in multiple layers as a pocket, so that there is an area for already filtered fluid within the volume spanned by the pocket. From this area, the filtered fluid can flow into the suction line to the pump only along the defined cross section, which is formed, for example, by a defined opening in the pocket.
- a support body can preferably be provided, which supports the formation of the space and in particular prevents the filter material from collapsing.
- the suction line specifically describes that portion of the fluid delivery line that is downstream of the filter in the usual direction of flow (from tank to pump) and upstream of the pump.
- the line is on the suction side of the pump.
- the suction line can also extend along individual housing sections of the conveying device.
- a part of the housing which also forms the frame for the filter material or accommodates it, can be designed as part of the suction line.
- the frame serves in particular to fix and/or shape the filter material.
- an additional support structure the frame, may be required to stretch the filter material and thus create enough filter surface.
- the frame can have fixing points to which the filter material can be connected.
- the frame can also have a number of webs and ribs, which form a framework that spans a space within which the filter material is preferably arranged.
- the frame can in particular be part of the fluid conveying path, which is upstream of the pump, so that the frame has a connection point, for example, at which the filter material is connected to it, so that the filtered fluid from the volume spanned by the filter material can flow through this connection point can flow into the suction line.
- the frame is part of the housing of the device and is only formed by a connection point or the connection point for the filter material and, if necessary, also forms a support surface on which the filter material can be supported at least partially, in particular on one side.
- the connecting element is provided, which is used to create a fluid-tight and durable connection between the filter material and the frame.
- the filter material and/or the connection point on the frame can have connecting pieces for this purpose, which can be connected to the connecting element in a simple manner. In particular, grooves, projections, threads or other profiles can be provided for this purpose.
- the connecting element can be an additional component that is connected to the frame and the filter material, or it can be permanently installed on one side.
- the connecting element can be firmly connected to the filter material, so that only one additional connection between the connecting element and the frame has to be created.
- the connecting element with the attached filter material can thus be pressed or screwed into a receiving area on the frame, for example, or connected in some other way.
- the connecting element can also be firmly connected to the frame, so that the filter material is pressed or screwed into the connecting element.
- the connection principle remains the same.
- the connecting element locally fixes the filter material in relation to the frame.
- the frame is preferably part of the housing of the device.
- the device is constructed in such a way that it has a pot-shaped housing which is inserted into a tank through an opening in a tank wall, preferably the wall forming the base, and is connected to this wall via a circumferential flange.
- the pump and possibly other elements, such as the control device, are preferably arranged on the side of the pot-shaped housing facing away from the tank and are therefore not in direct contact with the fluid. It is also advantageous if the frame has a fluid line which is in fluidic contact with the pump, the fluid line on the frame having an inlet opening to which the filter material is connected by means of the connecting element. The inlet opening is located locally directly adjacent to the connection point of the filter material to the frame.
- the inlet opening is part of the connection point, so that it is ensured that the fluid from the space spanned by the filter material can only flow directly into this inlet opening and thus into the downstream fluid line.
- the fluid line can be formed, for example, by a short section, such as the bore in a wall of the housing, or also by a longer channel section running in a wall, or a pipeline.
- the fluid line can be identical to the suction line, which is upstream of the pump in terms of flow and downstream of the filter.
- a preferred exemplary embodiment is characterized in that the connecting element creates a fluid-tight connection between the filter material and the fluid line.
- the connecting element is thus a sealing element which seals the connection between the filter material and the connection point on the frame.
- the device is specifically designed in such a way that a missing connection element or a damaged filter element leads to a leak, as a result of which the function of the device can no longer be guaranteed.
- opening the connection between the filter material and the frame leads to the destruction of the connecting element, so that the functionality is no longer guaranteed and the connection is physically unstable and/or fluidly leaking.
- connection element creates a connection between the frame and the filter material that cannot be detached without being destroyed.
- One Non-destructive non-detachable connection is characterized in particular by the fact that the connection between the elements to be connected can only be established once during regular assembly. A subsequent opening of the connection leads to destruction or at least substantial damage to the connection element.
- the non-destructive non-detachable connection is produced by a bayonet lock.
- This is advantageous in order to produce the connection, for example by twisting the two components to be connected relative to one another, or in a particularly preferred embodiment only to twist the connecting element relative to the filter material and/or to the frame.
- a bayonet lock does not require a high angle of rotation of the parts involved in relation to one another, so that a durable connection can be produced even in confined spaces.
- the non-destructive non-detachable connection is formed by pawls, which break in the opposite direction to the locking direction when a sufficiently high force is applied.
- Pawls are formed, for example, by shaped bodies that protrude radially inward from the inner circumference of an opening and are set at an angle in the circumferential direction. This can preferably be formed on the connecting element designed as a ring.
- a profile is provided, for example, which is designed in such a way that the pawls slide over this profile in one direction of rotation, but locking occurs when the pawls slide in the opposite direction over the Profiling are performed.
- this principle is implemented, for example, in a freewheel of a bicycle hub.
- the profiling on the outer circumference and the pawls can be configured in a variety of ways.
- the core idea is that the two elements, in particular the connecting element and the filter material and/or the frame, can be rotated relative to one another in one direction of rotation and are blocked in the opposite direction to one another. Should a force be applied to the connection sufficient to break the pawls, the connection will disengage and a strong and fluid-tight connection can no longer be established.
- the closing direction of the non-destructive, non-detachable connection is rotary or translatory.
- the connection is established via a translatory movement or a rotary twist.
- a bayonet connection is preferably produced by twisting, while a plug-in connection, for example, is produced by means of a linear translational movement.
- the principle of the pawl can also be used in a plug-in connection, which is generated by a translational movement.
- blocking elements protruding from the inner circumference can be fixed by being pressed over a bead or into a groove, as a result of which a firm, fluid-tight connection is produced by a positive fit.
- the application of a force in the opposite direction to the insertion direction finally leads to the locking elements being destroyed by shearing off.
- the non-destructive, non-detachable connection is created when connecting the filter material to the frame by means of the connecting element and is destroyed when the filter material is released from the frame. This is particularly advantageous since, according to the invention, the connection is to be created once during assembly, and disassembly and reassembly is to be avoided.
- the connecting element is designed as a ring, with the connection of the connecting element to the filter material and/or to the frame being designed so that it cannot be detached in a non-destructive manner.
- the connecting element is preferably a ring, with the connection points on the frame and/or on the filter material preferably having a corresponding cross section, so that the ring can be attached to them.
- the connecting element as a ring can be arranged on the filter material or the frame and can be connected to it permanently or detachably, for example by screwing. The connection with the respective other element is then created by the non-destructive non-detachable connection.
- the connecting element can have a screw thread on one side, with which it is screwed onto the frame, for example.
- the filter material is connected to the connecting element, for example, with a bayonet connection with an indestructible, non-detachable connection.
- the ring-shaped connecting element can have, for example, two sections which can be rotated relative to one another and which, after the filter material has been inserted, are rotated in relation to one another and thereby fix the filter material with a connection already described above. This allows installation in a spatially limited work environment and also allows the connection element to be easily replaced after the connection to the filter material has been destroyed.
- the connecting element can preferably be designed in such a way that loosening the screw connection to the frame also automatically leads to the destruction of the connection to the filter material.
- This can be achieved in that the two relatively rotatable sections of the ring are designed in such a way that tightening of the ring at the connection point of the frame is possible, whereas loosening the ring from the connection point leads to destruction of the locking blades.
- This can be achieved, for example, in that the two sections that can be rotated relative to one another are rotated relative to one another when released in such a way that the pawls be destroyed and thus the safe and fluid-tight connection is no longer guaranteed.
- the screw connection can also be produced with the filter material, and the non-destructive non-detachable connection with the frame.
