Definitions
- the invention relates to a liquid purification element for cleaning a liquid.
- the liquid purification element is particularly suitable to filter a liquid additive for exhaust gas purification (in particular a urea-water solution) or to free it of impurities and / or to collect gas bubbles present in the additive.
- the liquid purification element can be used for example in a motor vehicle in a device for taking a liquid additive from a tank.
- Liquid additives are used in motor vehicles, for example for exhaust gas purification, in order to reduce nitrogen oxide compounds in the exhaust gas of an internal combustion engine. This is referred to as the selective catalytic reduction (SCR) process.
- SCR selective catalytic reduction
- urea-water solution is usually used in the SCR process.
- a 32.5% urea-water solution for exhaust gas purification is available under the trade name AdBlue®.
- AdBlue® AdBlue®
- the urea-water solution is converted into ammonia.
- the nitrogen oxide compounds in the exhaust gas then react with the ammonia to harmless substances such as CO 2, H 2 O and N 2 .
- liquid additives may have impurities.
- Contaminants in urea-water solutions are, for example, particles that have entered a tank during refueling.
- Another group of impurities are crystalline urea precipitates.
- gas bubbles can occur, which in particular dere exact dosage or promotion of the liquid additive can affect.
- Impurities in the liquid additive may also cause problems in the exhaust treatment device. This is especially true if the impurities are solid (not redissolvable) particles. Such contaminants can be aggressive in an exhaust treatment device and cause increased wear there.
- the problem with such a liquid cleaning element is that it can clog. Therefore, interchangeability and recoverability of a liquid purification member is advantageous.
- the liquid cleaning element should be operational for as long as possible without clogging.
- a particularly advantageous liquid purification element is to be specified, which is suitable for the purification of liquid additive for the exhaust gas purification (such as urea-water solution).
- liquid additive for the exhaust gas purification such as urea-water solution.
- a multi-layer liquid cleaning member having a liquid-permeable cover sheet and a liquid-tight base, the base having a suction port for sucking liquid through the liquid cleaning member, and at least the cover sheet and the base being connected to each other by a joint, the base being at least partially has structured surface towards the top layer.
- the liquid cleaning element preferably represents a substantially flat or slightly curved element as a whole, which has a thickness which is substantially less than the maximum areal extent along the cover layer or along the base.
- the liquid purification element is preferably flexible. It can thus (plastically and / or elastically) deformed and in particular bent.
- the liquid purification element can in particular be adapted to the surface of a (cylindrical) housing or to the surface of a tank, either retaining this shape in a dimensionally stable manner and / or guided in corresponding holders.
- the liquid purification element can also be deformed when the liquid freezes and thus avoids the ice pressure or the volume expansion associated therewith. It may be extended when the liquid freezes inside the liquid cleaning element (and thus self-expanding).
- the liquid purification element is suitable for sucking in liquid through the (preferably single) suction connection.
- the suction connection can be designed as a (single) opening in the base, possibly with a protruding attachment piece (eg in the manner of a cylindrical extension).
- the basis for the liquid is not penetrable, so that a targeted delivery only via the suction port (or a plurality of suction ports, which is preferably limited to two, three or four) takes place.
- the liquid purification element can pass into the liquid purification element through the (in particular large area) liquid-permeable cover layer and then flow (also) between the cover layer and the base (also) to the suction connection.
- the liquid cleaning element is designed so that from any point of the cover layer from a liquid-permeable flow path to the suction port exists.
- the suction connection is arranged close to the connection.
- the suction port is located at a distance of less than 2 cm (centimeters) and more preferably less than 1 cm (centimeters) from the connection.
- the suction port is preferably positioned at an upper portion of the liquid purification member. As a result, the liquid is sucked from the bottom up through the liquid purification member to the suction port.
- the liquid purification element has a selective permeability to a particular liquid.
- the liquid purification element of a ne high permeability to urea-water solution and low permeability to air may be provided by at least one of the layers of the liquid cleaning element (eg, the topsheet).
- the selective permeability makes it possible to provide the liquid at the suction port in a highly pure form, even if the surface of the cover layer is only partially wetted by the liquid.
- the liquid-permeable cover layer may be formed, for example, by a perforated sheet material and / or by a flexible grid.
- the liquid-permeable cover layer preferably comprises a polymer material.
- the liquid-permeable cover layer may also consist of a metallic material.
- the liquid-tight base is preferably formed from a foil material and / or from a flexible plate.
- the liquid-tight base preferably also comprises a polymeric material; However, it can also consist of a metallic material.
- the liquid-tight base can also be configured as a preformed film structure or as a preformed shell structure.
- Such a preformed film or shell structure can be produced, for example, from a starting material by means of a press-molding process, in particular a hot-press molding process.
- a starting material for example, a plastic can be used.
- the liquid-permeable cover layer and the liquid-tight base are made of the same material. In any case, for use in the case of urea-water solution, a corresponding resistance and possibly also a certain "flexibility" in the case of ice-pressure occurring in the case of freezing are advantageous.
- the compound is in particular liquid-tight and can also be referred to as a "liquid-tight connection".
- the compound can also be at least partially permeable to the liquid. It is important that the compound prevents contaminants from getting between the top layer and the base.
- the connection represents a circumferential seam connecting the top layer and the base in their peripheral areas.
- the term "circulation” here means in particular that the connection forms a closed line-shaped section on the multilayer flexible liquid cleaning element
- the connection in particular runs around a point on the liquid purification element on which the suction connection is provided formed in an edge region of the (planar) liquid cleaning element.
- connection space (already described above) between the cover layer and the base is formed, in particular, by the structured surface of the base, which extends into the connection space in the direction of the cover layer or even as far as the adjacent layer. Due to the structured surface of the base can be at least partially set a distance between the base and the cover layer. This distance causes between the cover layer and the base of the connection space exists, which at least one targeted th flow path from the top layer towards the suction connection realized. Particularly preferably, the connection space is designed so that there is a targeted flow path from each point of the cover layer to the suction connection.
- the structured surface of the base may, for example, form a predeterminable arrangement of a plurality of grooves, chambers or the like in the connection space.
- the structured surface of the base is formed in an inner region spaced from an edge (and the suction port) of the base.
- the multi-layer liquid cleaning member has at least one additional separate liner disposed between the topsheet and the base.
- the liquid cleaning element is now carried out with three interconnected layers.
- This additional separate insert can perform a liquid cleaning function to ensure a particularly good cleaning of the liquid.
- the at least one separate liner in the joint is bonded to the topsheet and the base.
- the additional separate insert may also be a support layer that may be configured or selected to maintain the connection space between the cover layer and the base even with deformation of the liquid purification element and / or implement at least one targeted flow path from the cover layer to the suction port ,
- the liquid cleaning element is particularly preferred if at least one separate insert is arranged between the cover layer and the base, wherein the at least one separate insert comprises at least one filter layer. It is also advantageous if the filter layer comprises at least one of the following materials: a nonwoven material, a sponge material, a grid, a sieve, a fabric and a net. With a filter layer as an additional separate insert within the multi-layered liquid cleaning element, it is possible to filter out particles from the liquid permanently.
- the filter layer preferably has a depth filter characteristic. This means that impurities in the liquid are deposited within the filter layer and not just remain on a surface of the filter layer. This distinguishes a filter layer with depth filter properties z.
- a filter layer may for example be constructed of a non-woven material, which consists of polymer fibers and is produced for example by pressing and / or sintering. In the case of a nonwoven, the fibers can be arranged chaotically and / or ordered, so that in particular tissue and the like are also included here.
- the filter layer may also be partially made by a spray process, are spun in the filter fibers and sprayed onto a substrate.
- a filter layer is formed by the cover layer.
- the cover layer may have all the properties of a filter layer already described. If the top layer is formed as a filter layer, it is possible that within the liquid cleaning element no further separate insert is arranged and so the liner layer designed as a filter layer rests directly on the liquid-tight base. Furthermore, it is advantageous if at least one support layer is arranged between the cover layer and the base as at least one separate insert.
- a support layer it is meant, in particular, a structure which has no cleaning effect or filtering action for the liquid, but merely has the task of forming a flat connection space between the cover layer and the base and in particular between a filter layer and the base a free liquid flow to the suction port from any point of the liquid purification element is possible.
- a support layer may be formed in addition to the structured surface of the base. The support layer may in particular also lie between the base and a filter layer in the liquid purification element.
- liquid cleaning element Preferably, several separate deposits are provided within the liquid cleaning element, which separately realized each liquid cleaning functions (filter layers) and support functions (support layers).
- At least two support layers are provided with aligned passages, wherein the passages of the at least two support layers are oriented in different directions and the passages of the at least two support layers overlap each other, and so a flat channel system is formed.
- a flat channel system forms a connection space, which ensures the free flowability between the cover layer and the base.
- the structured surface of the base forms a planar channel system between the base and the cover layer.
- the basis can form a planar channel system, for example by elevations and depressions of the structured surface, which represent a distance between the base and the cover layer or between the base and the further separate liners between the base and cover layers. Due to this distance, a channel system is formed between the surveys, which forms the connection space already described above.
- At least one gas bubble reservoir is formed with the structured surface of the base between the base and the cover layer.
- this gas bubble reservoir is arranged in particular so that a (gravimetric) migration of the gas bubbles contained in the liquid is favored there and thus the gas bubbles can be removed from a channel conveyor system formed.
- Channels With pimples are meant substantially point-like or round, spatially limited From cambers of the base towards the top layer, which ensure a distance between the base and the top layer. Elevations mean larger (for example flat and / or linear) bulges on the basis in the direction of the top layer, which can also be configured, for example, as wave crests. Channels are recesses of the foundation, each of which provides a flow path between the topsheet and the base, in particular between the knobs / protrusions. Due to the various structures (knobs, elevations and channels) and a suitable arrangement of these structures on the basis, it is possible to ensure that the connection space between the base and the cover layer can also be directed from the different positions of the cover layer towards the suction connection can be.
- connection space between the base and the cover layer is increased towards the suction port, so that the flow through the connection space is adapted to each occurring in the connection space liquid flows and the flow velocities within the entire connection space of the liquid purification element substantially are constant. Since all of the liquid purified by the liquid purification element flows through the regions of the liquid purification element in the immediate vicinity of the suction connection and only a very small portion of the liquid flows far away from the suction connection, it is advantageous if the flowability in the vicinity of the suction connection is increased.
- a locally limited support layer may exist in the vicinity of the suction connection, which does not extend over the entire surface of the liquid cleaning element and which enlarges the connection space in the vicinity of the suction connection.
- the liquid cleaning element is advantageous if the base has a peripheral stepped edge on which the connection is formed.
- a welded joint may be formed in a particularly advantageous manner.
- a stepped edge is particularly easy to produce when the base is made using a compression molding process.
- a stepped edge is also provided on the cover layer. The offset edges of the base and the cover layer preferably fit together exactly.
- the liquid cleaning element is advantageous if the suction connection is formed by an opening in the base with a cylindrical extension.
- the liquid purification element can be connected to a removal port on a device for removing or for conveying a liquid. It is particularly advantageous if the opening is punched out of the material of the base or the like and the cylindrical extension is adhesively bonded or welded to the base.
- the cylindrical extension is preferably made of a polymeric material.
- the cylindrical extension may also be formed by a die-forming process in the manufacture of the base.
- the cylindrical extension preferably engages in a suction port of a device for removing or for conveying a liquid and is sealed fluid-tight with this suction port, so that all liquid, which is sucked through the suction port, passes through the liquid cleaning element and is cleaned accordingly.
- connection is formed with a weld with which at least the cover layer and the base are connected to one another.
- Such a weld may be particularly preferably formed on the peripheral stepped edge of the base.
- the cover layer and the base consist of the same polymer material.
- the welded joint may be made by a seam welding method in which a hot body which effects the welding is moved along the joint over the liner to weld the liner and base in the region of the joint.
- a separate liner disposed between the topsheet and the base is also sealed to the topsheet and / or the base in the welding process.
- the at least one separate insert has such material properties that a simultaneous welding with the cover layer and the base is made possible.
- a welding process is not the only way to form a connection to the liquid purification element.
- the liquid-tight Connection may include, for example, an adhesive connection or a clamp connection. It is also possible that different connection techniques (welding, gluing, clamping, etc.) are combined to form the connection.
- At least one further separate insert between the liquid-permeable cover layer and the liquid-tight base is provided between step b) and step d) in a method step b.2).
- This can be, for example, a filter layer or a support layer.
- the production method described is particularly suitable for producing the liquid cleaning element described here above, which is described in detail above. All the advantages and special technical features described above in connection with the liquid cleaning element can be transferred analogously to the production process. The same applies to the advantages and design features of the production method described below, which can be transferred to the liquid purification element in an analogous manner.
- the sequence of process steps a) to d) is not mandatory. As far as technically reasonable, the sequence of process steps a) to d) can be changed. Likewise, if appropriate, it is also possible for the method steps to be carried out at least partially simultaneously.
- the starting materials can be provided in each case as endless materials or strip material (for example in the form of coils). The starting materials are stacked and then the compounds are made.
- a deformation of the liquid-tight base takes place in a step b.l) (deformation step s).
- the liquid-tight base is provided with a structured surface.
- a compression molding method is very particularly preferably used. The starting materials are placed on each other and then the compounds are prepared.
- step c1 an additional process step c1) may be required, in which a portion of the starting materials is separated from the continuous materials or the strip materials.
- This step cl) can be carried out, for example, before or after step c).
- compounds for a multiplicity of liquid purification elements are provided in step d).
- This multiplicity of liquid cleaning elements can be provided next to one another and / or one behind the other on the starting material for the cover layer, the base or the optionally present separate insert.
- the individual liquid purification elements are separated from each other.
- the described method also makes it possible, in particular, for liquid purification elements having a different surface area or different size to be produced from common starting materials.
- Step d) can also be carried out in two sub-steps: Thus, in step d.l) an opening in the cover layer introduced and in step d.2) an extension be added. Step d.l) can be carried out, for example, before step c), while step d.l) can optionally also be carried out after and / or partly simultaneously with step d). It is also particularly preferred if step d) already takes place when the liquid-tight base is provided. This can be done, for example, in the context of a press molding method or hot stamping method, in which the structured surface is introduced into the base.
