    Manhole with rainwater flutter system
    The invention relates to a rainwater filter system and as described in the preamble of the first claim and a manhole comprising such a rainwater filter system.
    Such rainwater filter systems are already described in, for example, EP 2 365 140A2. EP 2 365 140A2 describes a rainwater filter system for partially filtering collected rainwater. The rainwater is collected on, for example, a roof and is further guided via roof gutters to an inlet channel. The inlet channel carries the collected rainwater to a container with a filter element therein. The filter element guides a first part of the collected rainwater to a first filter with large meshes and then to a filter with smaller meshes and then further on to a first outlet channel, transverse to the direction of flow of the rainwater, along which the filtered rainwater continues to a reservoir flows. A second outlet channel is provided in the direction of flow of the rain water to further divert a second part of water to, for example, a sewer system. The first filter in this way prevents impurities with a diameter larger than meshes of the filter, so that these impurities remain in the container and can possibly flush away via the second outlet channel to a sewer so that the second filter can further purify the rainwater and, depending on make the diameter of the meshes of the filter suitable for use as a flushing agent for toilets, watering gardens, for use in washing machines, cleaning, etc. The first outlet channel is located in the container at a lower height than the second outlet channel to prevent that the filtered water is lost through the second outlet channel in the sewer system. Since impurities can remain in the filter element during use, the meshes of the filter element are filled over time with impurities, as a result of which the filter can let through less and sometimes even insufficient water. It is therefore necessary to clean the filter element over time. For this purpose, the filter element is usually detachably mounted between the inlet channel and the outlet channels, so that the filter module can be taken out from between the inlet and outlet channels to clean the filter element. However, this is a time-consuming process. In addition, at least two wells must be dug out for this rainwater filter system, namely a first for the container comprising the filter element and a second for the reservoir to store the filtered rainwater.
    It is therefore an object of the invention to provide a rainwater filter system in which the need to clean the filter element decreases.
    To this end, the rainwater filter system according to the present invention is characterized in that the filter element is designed with spreading means and the filter element is substantially flat.
    Such a rainwater filter system has the advantage that the spreading means allow the rainwater to be distributed evenly over virtually the entire surface of the filter element and any impurities present accumulate less at a specific location or specific locations on the filter element. The spreading agents also make it possible to filter a larger volume of rainwater. The filter element is of essentially flat design such that the thickness of the water layer perpendicular to the filter element is substantially uniform over the entire surface of the filter element. This also helps to reduce the chance of an accumulation of impurities. Moreover, the uniform thickness of the water layer ensures that the rainwater flows through the filter element without it locally remaining for a longer time above the filter element and for instance a coagulation of impurities could occur. The uniform thickness of the water layer also ensures that the spreading means are not flooded locally and, therefore, the even spread of the rainwater over virtually the entire surface of the filter element is realized less effectively.
    According to the present invention, the spreading means are profiles, more particularly the profiles are protrusions, and further the profiles are one or a plurality of V-shaped protrusions, the point of which is directed towards the inlet channel against the direction of guidance of the first part of the collected rainwater. For example, the spreading means may comprise at least one V-shaped protrusion, for example one V-shaped protrusion, the point of which is directed towards the inlet channel against the direction of guidance of the first part.
    The presence of the profiles, in particular the protrusions, not only ensures an improved distribution of the rainwater over the surface of the filter element, but also delays the flow of the rainwater over the filter element and results in less rainwater from the filter element. inlet channel to the outlet channel of the rainwater filter system passes along the guide surface of the filter module and is therefore not filtered. In addition, the presence of the profiles can cause the flow to change from a turbulent to a laminar flow. Without wishing to be bound by any theory, profiles are in the form of at least one V-shaped protrusion, preferably several V-shaped protrusions, the point of which is directed towards the inlet channel against the direction of guidance of a first part of the collected rainwater particularly suitable for obtaining the effects described above.
    In a further embodiment of the rainwater filter system according to the present invention, the profiles are a plurality of V-shaped protrusions and one pair of respective sides of at least two V-shaped protrusions are in line with each other.
    When one pair of the sides of the V-shaped protrusions are in line with each other, it is suspected, without wishing to be bound by any theory, that the flow of rainwater is spread over the filter element in such a way that a particularly favorable uniform distribution of the rainwater is obtained over the filter element, resulting in an improved amount of filtered rainwater per unit of time. Without wishing to be bound by any theory, the inventors believe that this is due to the shape and position of the protrusions, which ensure that a more laminar flow of rainwater is obtained. The flow of rainwater with a laminar flow over the filter element would thus result in an improved amount of filtered rainwater per unit time.
    In a further embodiment of the rainwater filter system according to the present invention, the filter element comprises lath-shaped elements. The slat-shaped elements are furthermore preferably arranged transversely to the direction of guidance. More preferably, the lath-shaped elements have a step-like section, the section tapered from top to bottom of the filter element so that the upper surface of the lath-shaped elements at the top of the filter element is wider than at the bottom of the filter element.
    In a further embodiment of the rainwater filter system according to the present invention, the filter element is enclosed by a frame.
    The presence of a frame enclosing the filter element reduces the risk that rain water without having been filtered flows away between the outer edge of the filter element and the supporting edge on which the filter element rests when it is mounted in the guide surface.
    In a further embodiment of the rainwater filter system according to the present invention, the filter element has a substantially rectangular shape. Preferably, the filter element has a square shape in order to give more rotational symmetry to the filter element.
    This shape simplifies the production of the filter element and corresponds well with the typical shape of the surfaces through which rainwater often has to be filtered, such as the diameter of manholes.
    The invention also relates to a manhole comprising the rainwater filter system according to the invention, characterized in that the filter module, and more preferably the filter element, extends substantially over the entire cross-section of the manhole.
    By placing the rainwater filter system according to the invention in a manhole where the filter module and preferably the filter element extends substantially over the entire cross-section of the manhole, virtually the entire surface of the manhole can be used as a guiding surface to filter rainwater and in this way the largest possible volume of rainwater per unit of time can be filtered and the volume of rainwater can be limited which is drained unfiltered through the outlet channel of the rainwater filter system along a guide surface of the filter module, which is of particular importance for industrial applications, for example.
    In further preferred embodiments of the manhole according to the present invention, the filter element is removably mounted between the inlet channel and the outlet channel. Such a mounting of the filter element allows the filter element to be taken out more easily from between the inlet channel and the outlet channel, so that the filter element becomes more easily accessible for, for example, cleaning.
    In further preferred embodiments of the manhole according to the present invention, the filter element is clampedly mounted between the inlet channel and the outlet channel. Such an assembly on the one hand allows the filter module to be removed easily and without the use of further tools, while the chance that the filter module undesirably leaves its correct position between the inlet channel and the outlet channel is reduced.
    In further preferred embodiments of the manhole according to the present invention, the filter element is removably mounted in an upward direction. Since the filter element according to the present invention is mounted above a manhole, the manhole being provided to collect the second part of the collected rainwater, the horizontal movement space around the filter module to remove the filter module is often limited, so that an upwardly removable filter module is considerably easier to remove. According to preferred embodiments of the present invention, the filter element comprises for this purpose one or more handles which make it easier to lift the filter element from its position, often sunk in the filter module.
    In further preferred embodiments of the manhole according to the present invention, the filter module is connected along the guide surface to the inlet channel through a first protruding part of the inlet channel on which a first end of the filter module rests. In further preferred embodiments of the manhole according to the present invention, the filter module is connected along the guide surface to the outlet channel through a second protruding part of the outlet channel on which a second end of the filter module rests. More preferably, the first and / or second protruding part and the first and / or second end comprise a cooperating set of a rib and a groove for mounting the filter module on the inlet and / or outlet channel. Such an embodiment permits positioning of the filter module between the inlet channel and the outlet channel in the guiding direction.
    In further preferred embodiments of the manhole, the cooperating set of the rib and the groove are provided with a seal. Such a seal allows an improved watertight connection between the inlet channel and / or the outlet channel on the one hand and the filter module on the other hand.
    The invention will be further elucidated on the basis of the description below and the accompanying figures of preferred embodiments of the rainwater filter system according to the present invention.
    Figure 1 shows a top view of a rainwater filter system according to the invention.
    Figure 2 shows a perspective view of a filter element as described in the invention.
    Figure 3 shows a section of a manhole according to the invention.
    Figure 4 shows an overview of a filter module 3 according to the present invention.
    The rainwater filter system 1 shown in Figure 1 comprises an inlet channel 2, a filter module 3 and an outlet channel 4. The inlet channel 2 supplies collected rainwater to the filter module 3. The filter module 3 conducts a first part of the collected rainwater from the inlet channel 2 to the outlet channel 4 via a guide surface 5 of the inlet channel 2, filter module 3, outlet channel 4 along a guide direction. A second part of the collected rainwater is diverted by the filter module 3 through a filter element 6. The filter element 6 is arranged in the plane of the guide surface 5 over substantially the entire surface of the guide surface 5.
    The inlet channel 2 is provided for supplying rainwater to the rainwater filter system 1. To this end, the inlet channel 2 is connected, for example, to means that collect rainwater such as, for example, a system of drainage, gutters, well, pipes, etc. Preferably, the inlet channel 2 is provided for be mounted on known standard plastic tubes with an outside diameter of usually 110 mm, 125 mm, 160 mm, 200 mm, 250 mm, 314 mm and 400 mm.
    The inlet channel 2 shown in Figure 1 is cylindrical and has a closed circular cross-section. However, this is not necessary for the invention and the inlet channel 2 can for instance also have an open top and / or have a square, rectangular, polygonal, etc. cross-section. However, a circumferential wall with a closed cross-section has the advantage that a larger volume of water can be processed without increasing the risk of water coming out of the inlet channel 2. An inlet channel 2 with a closed cross-section also offers the advantage that such an inlet channel 2 can be brought under the ground more easily since the closed cross-section prevents external particles from ending up in the stream of collected rainwater. A cross-section with a round shape has the advantage that it is more difficult for solid particles to remain behind in the inlet channel 2 in, for example, corners.
    The inlet channel 2 is preferably made of plastic, such as for example PVC, polyethylene and polypropylene, etc., but can also be made of other materials such as for example metal such as for example stainless steel, copper, etc.
    The inlet channel 2 is preferably adapted to be mounted in a wall. To this end, the inlet channel 2 preferably comprises means which allow the grip between the inlet channel 2 and, for example, cement or other adhesives to be increased in comparison with the grip between the cement or the other glue and a substantially smooth wall of the inlet channel 2. Preferably such means a rough surface disposed on the outer surface of the inlet channel or one or more protrusions arranged on the outer surface of the inlet channel 2. Preferably, the protrusions extend transversely of the inlet channel 2, which means the longitudinal positioning of the inlet channel 2 promotes. More preferably, the protrusions extend over substantially the entire circumferential direction of the inlet channel 2, whereby the contact surface becomes larger and the grip is further increased. The dimensions and shape of the protrusions can be further determined by those skilled in the art depending on the required grip and the materials used.
    The inlet channel 2 shown in Figure 1 has an end which is provided for connection to the filter module 3. Preferably, the filter module 3 is connected along the guide surface 5 to the inlet channel 2 through a first protruding part of the inlet channel 2 on which a first end of the filter module 3. The first protruding part can only be provided on the underside of the inlet channel 2, but the first protruding part can also be provided on the top side of the inlet channel 2 along substantially the entire circumference of the circumferential wall of the inlet channel 2 and thus a first end of the filter module 3. However, alternative means for connecting the filter module 3 to the inlet channel 2 are also possible, such as for example by means of a sleeve, brackets, welding, bolts, etc.
    The first protruding part and the first end of the filter module 3 preferably comprise a cooperating set of a rib and a groove. In one embodiment, a first end of the filter module 3 comprises the rib and the first protruding part of the inlet channel 2 comprises the groove. However, this is not necessary for the invention and the first protruding part of the inlet channel 2 can also include the rib and the first end of the filter module 3 the groove.
    Although not shown in Figure 1, the set of rib and groove provided in the first end of the filter module 3 and the first protruding part of the inlet channel 2 can be provided, for example, to make the connection between rib and groove more watertight. This can be done, for example, by fitting a seal, such as a seal ring, for example. However, such a construction is not necessary for the invention.
    The outlet channel 4 is provided for removing rainwater, in particular the first part of the collected rainwater, from the filter module 3. To this end, the outlet channel 4 is connected, for example, to a sewerage system, etc. Preferably, the outlet channel 4 is provided for mounting on known standard plastic pipes with an outside diameter of usually 110 mm, 125 mm, 160 mm, 200 mm, 250 mm, 314 mm and 400 mm.
    The outlet channel 4 shown in Figure 1 is cylindrical and has a round closed section. However, this is not necessary for the invention and the outlet channel 4 can also have an open top and / or have a square, rectangular, polygonal, etc. cross-section. However, a circumferential wall with a closed cross-section has the advantage that a larger volume of water can be processed without increasing the risk of water coming out of the outlet channel 4. An outlet channel 4 with a closed cross-section also offers the advantage that such an outlet channel 4 can be brought under the ground more easily since the closed cross-section prevents external particles from ending up in the stream of collected rainwater. A cross-section with a round shape has the advantage that it is more difficult for solid particles to remain behind in the outlet channel 4 in, for example, corners.
    The outlet channel 4 is preferably made of plastic, such as for example PVC, polyethylene and polypropylene, etc., but can also be made of other materials such as for example metal such as for example stainless steel, copper, etc.
    The outlet channel 4 is preferably adapted to be mounted in a wall. To that end, the outlet channel 4 preferably comprises means which allow the grip between the outlet channel 4 and, for example, cement or other adhesives to be increased in comparison with the grip between the cement or the other glue and a substantially smooth wall of the outlet channel 4. Preferably, such means a rough surface disposed on the outer surface of the inlet channel or one or more protrusions arranged on the outer surface of the outlet channel 4. Preferably, the protrusions extend transversely of the outlet channel 4, which results in the longitudinal positioning of the outlet channel 4 promotes. More preferably, the protrusions extend over substantially the entire circumferential direction of the outlet channel 4, whereby the contact surface becomes larger and the grip is further increased. The dimensions and shape of the protrusions can be further determined by those skilled in the art depending on the required grip and the materials used.
    The outlet channel 4 shown in Figure 1 has an end which is provided for connection to the filter module 3. Preferably, the filter module 3 is connected along the guide surface 5 to the outlet channel 4 by a second protruding part of the outlet channel 4 to which a second end of the filter module 3. Although the second protruding part is only provided on the underside of the outlet channel 4, the second protruding part can also be provided on the upper side of the outlet channel 4 along substantially the entire circumference of the circumferential wall of the outlet channel 4 and thus the end of the outlet channel 4. filter module 3. However, alternative means for connecting the filter module 3 to the outlet channel 4 are also possible, such as for example by means of a sleeve, brackets, welding, bolts, etc.
    The second protruding part and the second end of the filter module 3 preferably comprise a cooperating set of a rib and a groove. In one embodiment, the second end of the filter module 3 comprises the rib and the second protruding part of the outlet channel 4 comprises the groove. However, this is not necessary for the invention and the second protruding part of the outlet channel 4 can also include the rib and the second end of the filter module 3 the groove.
    Although not shown in Figure 1, the set of rib and groove provided in the second end of the filter module 3 and the second protruding part of the inlet channel 2 can be provided, for example, to make the connection between rib and groove more watertight. This can be done, for example, by fitting a seal, such as a seal ring, for example. However, such a construction is not necessary for the invention.
    The filter module 3 shown in figures 1 and 2 is rectangular, in particular square. However, this is not necessary for the invention and the filter module according to the present invention can also have any other cross-section, shape and dimensions. Other cross-sections are therefore also possible for the filter module 3, such as for example polygonal or round, etc. A round cross-section has the advantage that solid components are less easily left behind in the filter module 3 behind, for example, an angle.
    The filter module 3 is preferably made of plastic, such as, for example, PVC, polyethylene and polypropylene, etc., but can also be made of other materials such as, for example, metal such as, for example, stainless steel, copper, etc. Preferably, the filter module is provided to provide a manhole to be anchored, for example bricked. Although not shown in the figure, the filter module 3 is preferably provided to be connected to inlet and / or outlet channels of different diameter. To this end, the first and the second end of the filter module 3 can for instance be provided with a tapered diameter which can be cut to the desired diameter. In addition, it is possible to provide the tapered diameter in steps, each step corresponding to a common diameter for inlet and / or outlet channels. It is also possible, in addition to or instead of the tapered first and second end, to provide an additional set of first and second ends on an additional pair of opposite sides of the filter module 3 so that by orienting the filter module 3 in the manhole the desired pair ends with the desired diameters with respect to the inlet and outlet channels can be positioned. Furthermore, in order to also position the filter element 6 in the filter module 3 relative to the inlet and outlet channels, the filter element 6 has a rotational symmetry, for example the filter element is square.
    An overview of an example of such a filter module 3, without filter element 6, is for example shown in figure 4.
    The guide surface 5 is substantially smooth in order to guarantee a good flow of the collected rainwater and to prevent solid parts of the stream of collected rainwater from preventing a smooth passage of collected rainwater along the guide surface 5. However, this is not necessary for the invention and the guide surface 5 can also contain corners and edges.
    The filter element 6 shown in Figs. 1 and 2 has the shape of a rectangular, in particular square, flat element which is arranged in the guide surface 5, over substantially the entire surface of the guide surface 5, the guide surface 5 being provided such that the impure collected rainwater is kept at least temporarily above the filter element 6. The filter element 6 comprises lath-shaped elements. In Figures 1 and 2, the lath-shaped elements extend in the longitudinal and in the width direction of the filter element 6. The distance between successive lath-shaped elements is thereby adapted to the required cleanliness of the second part of rainwater, whereby a smaller distance between successive lath-shaped elements ensures greater cleanliness of the second part of rainwater and greater distance ensures a more moderate cleanliness of the second part of rainwater. The distance between successive slat-shaped elements is preferably between 0.1 mm - 5 mm, more preferably 0.2 mm - 3 mm. The lath-shaped elements preferably contain a metal, more preferably a stainless metal such as, for example, stainless steel, stainless steel, etc., but may also be made of other materials such as, for example, plastic, such as for example polyethylene, polypropylene, PVC, etc. of multiple materials such as, for example, a mixture of a metal with a plastic, such as, for example, polyethylene and stainless steel.
    The filter element 6 can also comprise different lath-shaped elements that lie at different distances from each other. The different slat-shaped elements can also comprise different materials. For example, it is possible to combine first plastic slat elements with a second metal slat elements.
    As shown in Figure 1, the filter element 6 is preferably located in the filter module 6.
    The filter element shown in Figure 2 is enclosed by a frame 10. The frame 10 can be provided to be connected along a first end to the inlet channel 2, through a first protruding part of the inlet channel 2, to which the filter module 6 is connected. The frame 10 can also be provided to be connected along a second end to the outlet channel 4, through a second protruding part of the outlet channel 4, to which the filter module 6 is connected. The frame 10 preferably comprises a metal, more preferably a stainless metal such as, for example, stainless steel, stainless steel, etc., but may also be made of other materials such as, for example, plastic, such as for example polyethylene, polypropylene, PVC, etc. of multiple materials such as, for example, a mixture of a metal with a plastic, such as, for example, polyethylene and stainless steel.
    The filter element 6 is provided with spreading means 7, as shown in figures 1 and 2. The spreading means 7 shown in figures 1 and 2 are V-shaped protrusions, the point of which is directed towards the inlet channel against the guide direction of the first part of the collected part rainwater. The spreading means 7 can for instance also be a single V-shaped protrusion, the point of which is directed towards the inlet channel against the direction of guidance of the first part of the collected rainwater. In one embodiment, the filter element 6 comprises three V-shaped protrusions, at least one pair of the respective sides of two V-shaped protrusions 7 being in line with each other. The spreading means 7 preferably contain a metal, more preferably a stainless metal such as, for example, stainless steel, stainless steel, etc., but may also be made of other materials such as, for example, plastic, such as for example polyethylene, polypropylene, PVC, etc. of multiple materials such as, for example, a mixture of a metal with a plastic, such as, for example, polyethylene and stainless steel.
    The filter element 6 can preferably be lifted from the filter module 6, more preferably from the plane of the guide surface 5. This has the advantage that the filter element 6 can be easily cleaned or replaced where the filter module 6 can remain in, for example, the manhole. Since the filter element 6 can thus easily be replaced by a filter element 6 with other properties, the rainwater filter system 1 according to the present invention can also be easily adapted to the specific situation in which it is used, since for example the distance between successive slat-shaped elements, the material of the lath-shaped elements, etc. can be adapted to the specific situation.
    The filter element 6 is preferably removably mounted between the inlet channel 2 and the outlet channel 4. However, this is not necessary for the invention and the filter module can also be fixedly connected to the inlet and outlet channels 2, 4, for example by means of a weld connection.
    The filter element 6 is preferably clamp-tightly mounted between inlet and outlet channel 2, 4. However, the filter element 6 does not have to be clamp-tightly mounted and can also be mounted differently between the inlet and outlet channel 2, 4, for example by means of screws, bolts, welding brackets, etc.
    The filter element 6 is preferably removably mounted in an upward direction. However, this is not necessary for the present invention and the filter element 6 can also be removably mounted in other ways, for example laterally removable or removable downwards.
    By further providing a handle 11 on the filter element 6, preferably on the frame 10 as shown in figure 2 in order to increase the maximum usable surface area, the mounting of the filter module 3 can be further facilitated, especially if no additional mounting means such as bolts , screws, etc. were used. If the filter element 6 still needs to be cleaned after some time, the filter element 6 can simply be lifted from between the inlet and outlet channels.
    The filter element 6 shown in Figure 1 has two handles 11. However, a single handle 11 can also be provided, which then extends for example over the filter element 6, for example over the center of the filter element, so that the filter element 6 with a single hand can be lifted between the inlet and outlet channels. In addition, by providing a symmetrical provision of the handle 11, the filter element 6 can even be lifted stably from between the inlet and outlet channels. If the filter element 6 is to be lifted with a single hand, the weight of the filter element is preferably limited. To that end, the filter element is made, for example, from plastic, such as for instance polyethylene, polypropylene, PVC, etc. Moreover, such a filter element is relatively easy to make.
    Both the inlet channel 2 and the outlet channel 4 are preferably tubular as shown in Figure 1. Other embodiments in which the inlet channel 2 and the outlet channel 4 are designed differently, and in which, for example, dimensions, cross-section, shape of the different channels are configured differently, also possible. The shape and dimensions of the inlet and outlet channels 2, 4 are preferably adapted such that the filter module 3 can be easily mounted between the inlet and outlet channels 2, 4.
    A rainwater filter system 1 as shown in Figure 1 and described in further detail above is usually mounted above a collecting basin, usually a manhole 9, in which the rainwater purified by the rainwater filter system 1, the rainwater of the second part, is collected. In such an arrangement, the inlet channel 2 is fitted in a first side wall of the collecting basin 9 and the outlet channel 4 is mounted in an opposite side wall of the collecting basin 9. In the collecting basin 9 further means are provided for further transporting the rainwater from the second part to the place of use. However, it is also possible to connect the rainwater filter system 1 according to the present invention to the further transport system in such a way that the rainwater of the second part is not first collected in a collecting basin such as a manhole 9 but is collected directly in a transport pipe which transports it further to the place of use.
    In addition, it is also possible that the collecting basin 9 is not the definitive collecting basin 9 but is provided around the filtered water to a further location. For example, a filter module 3 can be provided which is provided below the filter element 6 with a collecting element comprising an additional output channel. That additional outlet channel is then, for example, in turn connected to the collection basin 9.
    According to preferred embodiments, the collecting element is, for example, plastic, such as for instance polyethylene, polypropylene, PVC, etc., in order to limit the weight. Other materials are of course also possible: for example metal such as for example stainless steel, copper, etc. Preferably the collecting element together with the filter module 3, more preferably made of the same material as the collecting element, are made of a single whole.
