    [0002] Flow separation system in multifilter equipment.
    [0003]
    [0004] Object of the invention
    [0005]
    [0006] The invention is designed to protect each of the internal filters that make up a multifilter equipment, intended for the purification of liquids, avoiding at all times that these filters are saturated with dirt or solid particles during their process of depuration or cleaning of the liquid; for this, the system of separation of flows of the invention is composed of a plurality of bodies called flow separators, each located around a filter, which with a defined configuration manage to retain the dirt particles before they reach the filter , control the flow to be cleaned by each of the filters and redirect the flows, avoiding mixing the flow rates between the different filters that make up the system.
    [0007]
    [0008] The system of separation of flows in multifilter equipment is composed of a plurality of flow separating bodies, each of which comprises a support structure composed of a certain base, through bars and a cover; around which is located, a screening element with helical configuration.
    [0009]
    [0010] The field of application of the invention is comprised within the sector of the manufacture of filtering equipment, for conducting installations of all types of fluids such as water, dairy, agri-food, pharmaceutical, desalination or similar; and specifically it is intended for the industry dedicated to irrigation facilities.
    [0011]
    [0012] Background of the invention
    [0013]
    [0014] Currently, the field dedicated to machinery for water treatment and cleaning, as is the case of multifilter equipment, has undergone a rapid evolution in recent times, mainly due to the development of its use in irrigation applications.
    [0015]
    [0016] This evolution has the objective of achieving a better use of hydraulic resources, especially in regions that have a natural shortage of water, where at the same time they have had to develop advanced irrigation techniques, such as drip irrigation and the irrigation by micro-sprinkling which achieve a high degree of water use. In this sense, it is known that the waters that are used in general for irrigation are water of poor quality, which are not intended for human consumption, and that often impurities waters are used, that although they do not constitute any inconvenience with Traditional irrigation techniques can be a serious problem in drip and micro-sprinkler irrigation facilities.
    [0017]
    [0018] In view of the foregoing, it is now necessary to place filters that avoid as far as possible the arrival of impurities carried by the water flow, to the aforementioned drip irrigation and micro-sprinkler installations. From the state of the art we highlight the so-called ring filters, for example the one presented in document ES1055543U disclosing a filter element composed of a plurality of slotted plastic rings through which filtering is carried out. These ring filters allow to face the problem of impurities; However, another problem arises, which is the derivative of the necessary cleaning and maintenance operations associated with its operation to eliminate impurities accumulated in them.
    [0019]
    [0020] In relation to the above, it should be noted that a series of self-cleaning filters have been known and used for a long time in which, from a substantially cylindrical housing, the they establish inside the same, two coaxial chambers, a perimeter and another axial, related to each other through a plurality of filter discs provided on their faces with slots, so that when these discs are superimposed on each other, said slots they convert into tubes of reduced caliber, which are what give these filters the filtering effect, the problem of these filters lies in their reduced self-cleaning capacity for large installations and higher flow demands.
    [0021]
    [0022] To solve the problem of cleaning the filters, other types of solutions are known, such as the one disclosed in document ES1059225U, where a solution is presented in which to a filter formed by a plurality of filter rings or discs, in which tubes are included that go through the support of the rings and that allow modifying the flow of the water, thereby improving the cleaning tasks of the assembly. This type of solutions has the disadvantage of presenting valid rigid solutions for installations with low flow demand, where the filters are not subject to high pressures.
    [0023]
    [0024] Therefore, for installations with higher flow demands and trying to compact the equipment to the maximum and save the installation, the tendency to use multifilters consisting of the technologies we have just discussed, that is, filters with circular and concentric rings, has begun to expand. such as disclosed in document ES1062189U, or solutions consisting of structural reconfigurations of the equipment as disclosed in document ES2319335 and internally adapting conventional or ring filters; however, it is known in the sector the disadvantage that by itself this type of rings, with the use is attached much dirt that together with the generation of unwanted flows of water, prevents proper cleaning of the different filters found located inside the equipment.
    [0025]
    [0026] In view of the antecedents existing in the state of the art, the existing one of any device or system that allows to separate the flows within a multifilter equipment is not known, as well as the fact that the flow is controlled within each filter so independent within the same team.
    [0027]
    [0028] For this reason, with the system of separation of flows in multifilter equipment object of the present invention goes one step further in the field of filtering equipment, since in this document is described a solution that is based on flexible physical separators and elastics that can be compressed or expanded as a function of the pressure and current of the liquid inside each filter, which allows the system to adapt to the conditions of the liquid; and where each filter is wrapped independently, so that no filters interact with others, thus obtaining a perfect seal inside this element and achieving the functionality of eliminating the undesired flow, thereby obtaining an improvement in the conditions of cleaning of the system in general, which minimizes maintenance work and in turn optimizes and prolongs the working time of the filters, in a manner different from what is known so far in irrigation or similar facilities.
    [0029]
    [0030] Below is a detailed description of the invention that completes these general ideas introduced in this point.
    [0031]
    [0032] Description of the invention
    [0033]
    [0034] The system of flow separation in multifilter equipment is composed of a plurality of bodies called flow separators. Each of these flow separators is located around each of the filters that make up the multifilter system of the system, protecting them from possible saturations, regulating the purification flow so that they do not get stuck and separating the flows between the different filters, which makes it possible improve its cleanliness, as will be described later.
    [0035] Each of these flow separating bodies or elements are preferably of hollow tubular geometry, and their dimensions are such that when they contain a filter or filtering element therein, perimetrally there is space between the walls of both elements.
    [0036]
    [0037] The flow separating body is formed by a support structure of material preferably rigid and by a sieve element with flexible helical configuration, which is supported by the structure and is integral to the movements of this.
    [0038]
    [0039] The support structure consists of a base, through bars and a cover. Said base is flat and has the singularity that its central axis has an axial cavity of a dimension or sufficient diameter so that a filter can be introduced through it and be housed inside it.
    [0040]
    [0041] In addition, said base also has a plurality of small cavities, located around the cavity previously described, with the purpose of locating or introducing through bars therethrough. These bars through one end are joined to the base through the cavities previously described, while their opposite ends are fixed to a so-called cap, which perimeter has the same dimensions as the base, is flat, compact and it positions parallel to the described base, being therefore confronted with it. According to the results obtained in tests, the preferential number of cavities and bars are five.
    [0042]
    [0043] Surrounding the bars that make up the support structure, specifically between the bars, the base and the lid as a wrapper, there is a sieve element fixed. This sifting or screening element is composed of a flexible and malleable material and has a spiral or helical configuration. The spiral sieve element has two types of sections in their configuration as a whole, defined as section of circular lines and section of radial lines.
    [0044]
    [0045] Both sections are superimposed on the entire spiral that is formed as a single piece, preferably obtained by extrusion. In this way, when the assembly of the flow separator body is stopped or in rest position protecting each of the filters of the multifilter equipment of the invention, the spiral is fully open and when the flow separator body is receiving water or in the position of work the spiral closes controlling the flow of entry.
    [0046]
    [0047] Once defined the body or flow separating element that is part of the system of the invention, we describe the system as a whole.
    [0048]
    [0049] As has been previously advanced, in the flow separation system in multifilter equipment object of the present invention, each of the filters that make up the equipment is contained within the previously defined flow separator body. When the system as a whole is at rest, that is to say that the system does not contain liquid inside it, the entire sieve spiral that constitutes the separator body is ringed, so that the separated body of flows is contraldo around the filter.
    [0050]
    [0051] Consequence of the two types of sections that make up the helical element, along the entire surface of the element there are interstices or small spaces forming channels that allow the gradual entry of the liquid inside. To do this, first of all, the liquid that you want to treat inside the multifilter equipment must be introduced. When the multifilter as a whole is being filled, all the flow separating bodies that make up the system are subjected to a compressive surface pressure on its walls. Then, through the interstices formed by the helical element, the liquid medium without impurities it is gradually introduced, thus regulating the flow rate gradually within the interior space of the separator body, where the filter is located. As the liquid is filtered through the so-called separator body, the pressure inside the said body increases, due to the flexible nature of the helical element together with the characteristic of the through bars, the flow separator body as a whole is stretched longitudinally. This fact implies that the helical element that is stretched solidly to the longitudinal movement of the said bars, acts at all times as a regulator, preventing in this case that more flow within the separator body than possible by its tubular volume. At this point it could be said that the flow separating element or body is in working position with the spiral or helical element open.
    [0052] Another detail that makes up the system of the invention, is that inside the multifilter equipment there are as many flow separating elements as filters. That is why each filter cleans optimally, since there is no exchange of flows between the different filters, since each of them is protected by a flow separator element that besides acting as the first dirt or solid particles retainer unwanted also prevents insubstantial currents from forming, separating the flows and preventing the mixing of other filter liquids, and achieving improvements in the cleaning, maintenance and performance of the whole system.
    [0053]
    [0054] To complete the description that is being made and in order to help a better understanding of the characteristics of the invention, a set of drawings is included as an integral part of the same, in which the following has been represented with an illustrative and non-limiting character.

    [0064] Figure 4 is a schematic representation of a longitudinal section of a flow separator body in working position during cleaning of the filter, when the helical element is fully open around the filter, correctly redirecting the flows.
    [0065]
    [0066] Figure 5 is a detail of the section of the helical sieve element, of the previous figure.
    [0067]
    [0068] Description of the drawings
    [0069]
    [0070] As can be seen in Figure 1, the flow separation system in multi-filter equipment object of the invention is composed of a plurality of bodies called flow separators (1). Each of these flow separating bodies or elements (1) is located around each of the filters (2) that make up the multifilter equipment (3) of the system, protecting them from possible saturations at the entrance of the liquid since each one of the aforementioned separating bodies (1) regulates the flow of depuration in each of the filters (2), besides separating the flows between them, in such a way that the clean water that leaves the equipment multifilter (3) is evacuated free of impurities, as shown schematically in the aforementioned figure 1.
    [0071]
    [0072] Figures 3 and 4 show that each of these flow separating bodies (1) are preferably hollow tubular geometry, and their dimensions are such that when they contain a filter (2) inside, perimetrally there is space between the walls of both elements.
    [0073]
    [0074] As can be seen in figure 2, the separating body (1) is formed by a support structure (11) of preferably rigid material and by a screening element (12) with flexible helical configuration, which is supported by the structure and is in solidarity with the movements of this. It is noted that in this representation the sieve element (12) is represented schematically, so that the position of the spiral within the set is clearly appreciated.
    [0075]
    [0076] The support structure (11) consists of a base (111), through bars (112) and a cover (113). Said base (111) is flat and has the singularity that its central axis has an axial through hole (111 ') of a dimension or diameter sufficient for a filter (2) to be introduced through it and be housed in its interior, appreciable in figures 3 and 4.
    [0077] In addition, said base (111) also has a plurality of small cavities (111 "), located around the hole described above, through which are inserted through bars (112). As can be seen in Figure 2, these through bars (112) at one end are joined to the base (111) through the cavities previously described, while their opposite ends are fixed to a so-called cover (113), which perimeter has the same dimensions of the base (111), is flat, compact and is positioned parallel to the base (111) described, being therefore faced with it.According to the results obtained in tests, the preferred number of cavities (111 ") in the base (111) and bars (112) are five, as shown in the aforementioned figure 2.
    [0078]
    [0079] In figures 3 and 4 it can be seen that fixed along the bars (112) that make up the support structure (11), specifically from the base (111) to its cover (113) through its through bars ( 112) as a wrapper, there is a sieve element (12). This sieve element (12) or screening element, is composed of a flexible and malleable material, and has a spiral or helical configuration. The spiral sifter element (12) in turn has two types of sections in their configuration as a whole, defined as section of circular lines (121) and section of radial lines (122), represented in figure 5.
    [0080]
    [0081] Both sections are superimposed on the entire spiral of the sieve element (12) which is formed as a single piece, preferably obtained by extrusion. In this way, as shown in FIG. 3, when the assembly of the flow separator body (1) is stopped or in rest position protecting each of the filters (2) of the multifilter system of the invention, the spiral is totally open; while as shown in figure 4, when the separator body (1) is in the cleaning position the spiral opens.
    [0082]
    [0083] Once the flow separating body (1) which is part of the system of the invention has been defined in detail, we now describe the system as a whole.
    [0084]
    [0085] As previously advanced, in the system of separation of flows in multifilter equipment object of the present invention, each of the filters (2) that make up the multifilter equipment (3) is contained within a separating body (1) previously defined. When the system as a whole is at rest, that is to say that the system does not contain liquid in its interior, the entire spiral of the sieve element (12) that constitutes the separator body (1) of flow is ringed, so that the separating body (3) is contraldo around the filter (2). Schematic representation of figure 3.
    [0086]
    [0087] Consequence of the two types of sections (121 and 122) that make up the sieve element (12), along the entire surface of the helical element there are interstices or small spaces forming channels that allow the gradual entry of the liquid inside. To do this, first of all, the liquid that you want to treat inside the multifilter equipment must be introduced. When the multifilter equipment (3) as a whole is being filled, all the separating bodies (1) of flow that make up the system are subjected to a compressive surface pressure on its walls (figure 3). Then, through the interstices formed by the sieve element (12), the liquid medium without impurities is gradually introduced, thus gradually regulating the flow within the interior space of the separator body (1), where it is located the filter (2). As the liquid is filtered through the so-called flow separating body (1), the pressure inside the said element increases, as a result of the flexible nature of the helical sieve element (12) together with the characteristic of the through bars ( 112), the separating body (1) as a whole is stretched longitudinally (Figure 4). This fact implies that the sieve element (12) with flexible helical configuration is stretched solidly to the longitudinal movement of the said through bars (112), which acts at all times as a regulator, preventing in this case that more flow within the separator body ( 1) of flows, than the possible one due to its tubular volume. At this point the separating body (1) is in working position with the spiral of the closed sieve element (12).
    [0088]
    [0089] Described sufficiently in what precedes the nature of the invention, taking into account that the terms that have been written in this specification should be taken in a broad and non-limiting sense, thus! as the description of the way to put it into practice.
