    DESCRIPTION

    Modular component of sectorized filtration.

    Object of the invention 5

    The present invention relates to a modular filter element, understood as a piece or element whose stacking forms a filtering surface. Said module allows the filtration of the fluids passing through it in a sectorized manner so that, unlike in the filtration modules present in the current state of the art, dedicated parts can be simultaneously arranged in a same filtering surface. to filtration, parts dedicated to backwashing, parts with different degrees of filtration, etc., thus increasing the possibilities of using the filter that makes up a multiplicity of said modules.

    More specifically, the shape of the modular filter element consists of a flat element 15 whose surface has at least two differentiated concentric bands, where one of them performs the function of filtering the fluid, then passing from or towards the other type of band, formed by radially defined holes, which with the stacking of modules form independent channels for the passage of water.

    Field of application of the invention

    The present invention will have application mainly within the industry of manufacturing of filtering equipment for driving installations of all types of fluids, being useful for the industry dedicated to irrigation facilities, the dedicated to petrochemical facilities, 25 pneumatic installations, etc.

    BACKGROUND OF THE INVENTION

    There are a multitude of types of fluid conduction installations in which a particle filtration is necessary. In view of this need, several technologies focused on particle filtration have been developed, the most notable being:

    - Bag filters
     35
    - Mesh filters

    - Cartridge filters

    - Ring filters 40

    - Deep bed filters (sand, activated carbon ...)

    - Rotary sieves
     Four. Five
    - Candle filters

    All these systems have their peculiarities that turn them into technologies of use in very specific installations. In the attempt to solve the main problems of two of the most widespread technologies, the mesh filters and the ring filters, the technology developed in this memory was devised.

    One of the main problems in filtering installations today is the fact that the filters need maintenance that is usually
    it increases the cost of the fluid produced and limits the quantity of fluid to be treated. On the one hand, the mesh filter has as its main drawback the need to backwash the mesh. For the removal of the particles that are trapped on the surface of the mesh, it is sucked causing a pressure differential contrary to normal flow. The most efficient way to clean these meshes is currently carried out by several nozzles of little diameter that run along said surface. The existence of these nozzles and their cleaning process greatly increases the cost of manufacturing and maintaining this type of filter. On the other hand, in the case of ring filters, the backwash must be done simultaneously to the entire filtering surface by means of a change in the flow direction of the water. This fact means that during the washing the filter stops functioning as a filtering element 10 per se.

    In ring filters, there is also the problem of the possibility of separation of the different elements from one another, producing a lack of selectivity of particles in the filtrate. By means of the solution described herein this problem is eliminated by joining all the 15 modular elements with a mechanical fixation that prevents their separation.

    Various documents describing filters that perform various functions are known by the owner of the present specification, such as, for example, utility model 1059225U, which describes a self-cleaning filter, or model 1056066 U, which discloses a similar device; the utility model 1004008 U which describes a filter capable of incorporating various types of filtering surfaces. Likewise, various documents relating to modular filtering elements are known, such as 1054796 U, which describes a ring that has valleys of constant section and plateaus of varying section, the patent with ES 2344181 A1 which describes a filtering disc having channels of Curved path that intersect 25 increasing the filtering surface.

    However, it is not known by the owner of the invention any device similar to that presented in this specification, where the modular filtering element allows water to be conducted in a sectorized way through it, with the consequent advantages that this new functionality offers.

    It is known the existence of a wide range of solutions for filtering using disks that use very different structures of microchannels, surfaces and materials that make up the disk to offer different solutions to problems that arise at the time of performing filtering functions. Given the eminently flat geometry of the present modular element it will be possible to use all those structures in the present invention, this point not being significant for the essentiality of the invention. Thus, although in the exemplary embodiment that is developed below, a perimeter band that uses a filtration system analogous to that of the filter discs described in document 40 1059225U, would be easily deductible for a person skilled in the art. the possibility of using any other filtering system, such as that of the patent ES 2344181 A1, for example.

    Following is a series of documents that will be discussed more in depth given their particular relevance: 45

    - Document ES2149566T3 discloses a filter that includes a package (28) of substantially flat filter elements, stacked one on top of the other, so that each filter element has a shaft centered in position by a shaft axially traversing the filter pack ; with a feeding tube for the unfiltered material 50 passing through the hub and several intake channels, which are regularly distributed in the perimeter direction of the shaft, which lead substantially radially outward, which are fed by the feed tube and that flow into an annular space of distribution, from which flows out the
    unfiltered matter substantially perpendicular to the lateral body of the shaft through an outlet slit, which remains above the intake channels radially towards the space between neighboring filter elements and where the contour of the annular distribution space, the outlet slit is divided by separating walls into exit channels. 5

    Although this document discloses filter elements provided with differentiated walls and channels, forming different areas within the element's own surface, said morphologies are designed with the purpose of facilitating the formation of the filter cake, not being possible in any case. moment to sectorize through its use 10 different flows of the fluid to be purified.

    - US4501663A discloses a filter formed by a stack of filter units. In one embodiment, the filter unit, which is a fundamentally flat disk, has two parts that fit together. One of them is a disk that includes a circular flat section with bands or concentric projections with radial channels cut in said bands. Said circular section is integrated with another outer circumferential circular zone and with another internal circular zone being the three concentric disc zones.
     twenty
    In the same way as in the previous document, the differentiated perimeter bands do not allow to separate different flows of the fluid to be treated, the similarity being with the invention proposed in the fact of presenting different morphologies with different purposes for the treatment of the fluid.
     25
    - GB1096739A discloses a filter formed by stacking filter units in the form of a flat disc with a central axial hole and a surface in which a band with transverse triangular grooves extends in a zig-zag, running along the face of the annular disc. In one embodiment (see figures 8 and 9), the disk may have two distinct concentric areas traversed by different shaved bands and with 30 different shapes.

    In this case the different morphologies lead to different filtration degrees. Again, no reference is made to the main advantage offered by the invention of the present specification, consisting of the sectorization of the fluid. Through the bands 35 differences described in the cited document, it is not possible to carry out this function.

    - WO2011129746A1 discloses a filter for fluids formed by superimposing or stacking several flat filtering elements defining a plurality of channels with at least two levels of filtering. The first coarse filter channels and the second coarse filter channels extend, generally radially, through most of the distance between the outer edge of the filter element stack and the central hole. In the event that two-stage filtration is required, the document discloses a type of filter elements such as that of Figure 5 in which the disk includes two arrangements of concentric filter channels. A first filter channel arrangement in the outer perimeter area that is responsible for the first filtering stage, trapping the thickest particles, a second filter channel arrangement, in the inner zone, which is responsible for the finest filtering. The shape of the filter elements can also be square, polygonal or other than the circular one (see figures 4A to 4C). It also discloses the possibility of a tandem filter by connecting in series two stacks of elements that can work with the fluid through both packages in the same direction or in countercurrent.
    As in the previous document, the possibility of sectoring the fluid is not reflected.

    Description of the invention
     5
    The filter element object of the present application is configured as an element of eminently flat shape, regardless of its external shape, which may adopt circular, square or any other geometry that allows it to adapt to the filter housing where it has to be installed. provide.
     10
    The present modular filter element is intended to be inserted in a filter cartridge, which will be filled with a multiplicity of parts identical to it until obtaining the filtering surface necessary to carry out the cleaning of the fluid considered necessary. As is logical, the filter cartridge to be used to obtain the functionalities offered by the present modular element will have to be capable of injecting differentiated flows of fluid in each of the sectors, thus not being a traditional filtration cartridge .

    The main characteristic of this modular filter element is that its surface is formed by perimeter bands of two different morphologies. While one of the 20 morphologies will have as mission the filtration of the fluid, the other band will serve to sectorize the zone of passage of the fluid, so that the different treatment of the water circulating through the different sectors is possible, as well as varying the characteristics of the filtering that is carried out.

    Said morphologies will consist on the one hand of a filtering perimeter band which, in a possible embodiment, has a groove similar to that of the rings used in the conventional ring filters, where in the previous part it has a zigzag pattern. which is responsible for distributing the water, while in the later it has a groove formed by concentric circles that limits itself to marking the micration of the filtration. On the other hand, the other morphology consists of a band that has a multiplicity of holes 30 which are separated both radially and in respective concentric subbands.

    By having a multiplicity of filter elements, the zigzag pattern of a band of one element will coincide with the concentric grooving of the next element, making this band the filtering zone. While the band of holes allows that after the superposition of several elements independent channels are created along the filter, channels that would have different uses but that facilitate the final mechanisms to be used for the automation of the filter. The coincidence of the channels of the two morphologies has to be emphasized in order to achieve an equal and independent distribution of flow rates in the final filtration zones.
     40
    The modular filter element object of the present specification will therefore be formed by at least two bands differentiated by their morphology. However, said bands can be repeated as many times as necessary depending on the final use to which it is to be allocated, thus being able to have any number of differentiated bands, where one of the morphologies described with the following will always be alternated, such as as 45 is described below, the function of each of the types of bands is complementary to each other, which forces each to be adjacent to the other.

    One of the main advantages of the modular filter element object of the present specification consists in the fact that it does not only act as a filtering element but also that the multitude of independent channels created by the perimeter band of holes allows the water to be filtered to be re-circulated through them so that a large number of treatments and different filtering or cleaning operations are possible without the need to modify the configuration of the filter element cartridge.
    The fluid to be filtered, being confined in the different channels that form the holes, can be conducted to perform different operations in one direction or another, being able to have inverse directions in adjacent channels or work by sectors of the element. In this way it is possible for one part of the cartridge containing the filter elements to function as a filter while another part is in the process of cleaning. Similarly, the depth of the water filtrate can be increased by collecting the water that has already passed through a grooved band in one or several channels and redirecting it back to those same grooves as many times as necessary. Thus, compared to conventional ring filters, another added advantage of the present invention consists in the great modularity that is had with this element without the need to store several spines in a single element under pressure, having a much higher mesh density. than these conventional elements.

    Another possibility presented by this invention consists of having different microuting of the grooves in each perimeter band so that, depending on the filtration needs of each moment, a greater or lesser degree of filtration is used simply by means of the appropriate conduction through the corresponding channels of the water to be filtered until it reaches the desired slotting.

    The positioning of the modular filter element is carried out by means of a mechanical anchor through various holes that are arranged in the outermost part. This anchoring guarantees the impossibility of relative movement between elements so that the risk of separation between them is avoided.

    Since the main and most novel characteristic of the filtering element recommended in this report is its ability to simultaneously carry out filtering tasks and sectorization of the Huido passage zone, different techniques and filtering methods not described in the present memory without altering the essentiality of the invention.

    Description of the drawings
     30
    To complement the description that is being made, and in order to facilitate a better understanding of the characteristics of the invention, the present report is accompanied as an integral part of the same, some drawings made with an illustrative and non-limiting character, which then we proceed to describe:
     35
    Figure 1.- A plan view of the anterior part of the modular filter element is shown. In this case said element has three perimeter bands, where the outer band and the inner band consist of grooves of different micrajes for filtering the water, while the intermediate band consists of holes arranged two to two separated from each other, where the holes located more to the outside they communicate with the outer perimeter band while 40 those located in the interior do it with the inner perimeter band. An extension of each of the bands in the figure has been made to facilitate its observation.

    Figure 2.- A plan view of the anterior part of the element of the previous figure is shown, with an enlarged detail where the concentric grooving of the outermost band is observed. Four. Five

    Figure 3.- The isometric of a set of assembled elements is shown forming a filter surface ready to be inserted in a filter cartridge.

    Description of the preferred embodiment 50

    In view of the mentioned figures, and in accordance with the numbering adopted, an example of a preferred embodiment of the invention can be observed, which comprises the
    parts and elements that are indicated and described in detail below, the present example not intending to limit the scope of this example at all.

    The modular filter element is shaped like a circular crown of 1 mm thickness whose surface has three differentiated perimeter bands. In the present example, since the filter element is circular geometry, the bands form concentric circles, although the base geometry can be of any type, being solely conditioned by the geometry of the cartridge in which the set of elements has to be inserted. mount.

    The outer circumferential band (1) has a zigzag groove (4) in its front part formed by a relief projecting 0.5 mm above the base of the circular crown, and whose raised parts will settle over the concentric groove (5) of the front part of the perimeter band (1) of the annex filtering modular element. Said concentric grooving in turn will have a height of 0.01 mm and a separation between ridges of 0.01 mm.
     fifteen
    The zig-zag of the groove (4) of the outer peripheral strip (1) will be punctually interrupted by the holes for the mechanical fixing (10) of the elements, being continued at said points by straight lines that will return to the previous form a once the hole for mechanical fastening (10) has been passed.
     twenty
    Following the outer circumferential band (1) an intermediate perimeter band (2) is arranged, which has a series of holes (6) defined by a multiplicity of radially spaced-apart walls (7). Furthermore, these holes (6) are divided into two bands, one outer and one inner, by means of a concentric separation wall (8) arranged in the central part of the intermediate band (2). 25

    Both the radial (7) and concentric (8) walls will have a height with respect to the base of the circular crown equal to that of the radial groove (4) of the outer (1) and interior (3) perimeter bands, and will have a geometry such that they will be stackable, thus fitting the walls of an element into those of the attached filtering elements, so as to avoid the possibility of displacement between them. Thus, the union of a multiplicity of filter elements will create through the orifices (6) a series of channels through which the water will be circulated.

    Finally, in the innermost part of the crown circulates a new inner perimetric band (3) is arranged which will have a configuration analogous to that of the outer perimeter band (1), modifying the dimensions of reliefs that make up the radial groove and the concentric grooving of the anterior and posterior parts respectively.

    The transition between two different types of band is carried out in such a way that the radial walls (7) connect in the front part of the element with the closest end of the radial groove 40 (4) so that a closed space is formed, from which the water circulating through the channels formed by the holes (6) can only exit through the grooves of the outer and inner perimeter bands. In the rear part of the element the radial walls (7) will be connected to the closing walls (9) arranged parallel to the concentric groove (5), so that it is separated from the hole to force the passage of water through the wall. anterior part of the filter element.

    An example of the advantages offered by the present element may be the fact that the channels created by the holes (6) of the intermediate band (2) can be used to transport water separately, carrying water through the outer holes for filtering at 50 ° C. through the outer perimetric band (1) while at the same time by the inner part is proceeded to wash the inner perimeter band (3) by driving water from the inner part of the crown through said inner perimeter band (3) and dislodging the water with waste through the channels created by the band of inner holes without it coming into contact
    At no time with the water intended for filtration that circulates simultaneously through the channels created by the outer holes of the intermediate band (2). Once the washing cycle has been completed, the direction of the water flow can be alternated and then proceed to clean the outer perimeter band (1) while the inner perimeter band (3) performs filtering functions at that moment. 5
