Abstract

The present invention relates to a "Complete classification and filtration system for rainwater" (100) for the purposes of utilizing rainwater. The system is capable of eliminating turbid/unfit water prior to initiating the filtration process, thereby safeguarding the filtering element (31) and thus increasing its service life. This is possible because of the water-monitoring devices inside a reading chamber (22), which read water-flow parameters, such that a control module (60) can analyse and classify the captured water, the filtering element (31) being placed or not being placed in an actuation position. The control module (60) can be programmed to select water on the basis of a variety of parameters, in accordance with the ultimate use intended for the captured water. The system (100) is capable of monitoring the concentration of accumulated detritus in the filtering element (31), implementing an automatic cleaning cycle, thereby avoiding constant wastage of water.

Description

CLASSIFICATION SYSTEM AND TOTAL PLUVIAL WATER FILTERING

RAISED

FIELD OF THE INVENTION

[01] The present invention refers to a “System for the classification and total filtration of rainwater collected” for the purpose of harnessing rainwater. This system is capable of adapting the filtering capacity to variations in rainfall intensity, in addition to classifying rainwater and protecting the filtering medium, eliminating debris without wasting water.

[02] The “System for classification and total filtration of rainwater collected”, hereinafter also referred to as “total system”, is provided with means capable of measuring the turbidity of a water flow based on the measurement of the absorption of a beam of water. light, as well as light scattering, electrical conductivity and the “PH” of this water flow, in order to obtain data to better classify rainwater according to the purpose of application. These data are also used to prevent an inadequate flow of water from making contact with the filter media of that total system.

RELATED TECHNIQUE

[03] Over time, rainwater catchment surfaces accumulate a high concentration of debris such as dust, manure, small animal remains, insects, etc. After the beginning of a rain, these first collected rainwater are polluted by these dirt deposited on the catchment surfaces. In this way, water becomes contaminated by contact with this debris and this pollution, making it an unsuitable liquid for use, which can even harm human health.

[04] In locations with high urban or industrial concentration, the atmosphere contains a large concentration of polluting substances in suspension. Much of this air pollution is captured by rainwater mainly during the first moments of precipitation. This water can be characterized, depending on its “pH”, as acid rain, which can damage the equipment and / or components, such as the filter mesh, among other parts.

[05] When there is precipitation, after a period of drought, the first water flows also capture the dirt from the atmosphere and the dust deposited on the catchment surfaces. These dirt, which includes small particles, mix the first waters, being suspended in the liquid, making the water unqualified and cloudy.

[06] This type of water is characterized as cloudy because it presents a large amount of suspended solids, finely divided or in a colloidal state, which makes the water aesthetically undesirable and with a higher rate of microorganisms potentially dangerous to human health. The disinfection of this water, to inactivate viruses and microorganisms, is carried out more easily according to the level of turbidity, that is, the less turbid the easier it is to disinfect.

[07] With the continuity of the rain, the waters become clearer due to the elapsed time and / or the increase in the intensity of rain, causing the cleaning of the catchment surfaces. However, with the increase in meteorological precipitation, the heavier elements, such as leaves, insects and garbage, are dragged into the collection and recycling systems.

[08] These larger-sized debris tend to accumulate in the filter elements of filter devices known in the art. With this, there is a reduction in its filtering capacity, which can contaminate the filter element.

[09] The accumulation of plastic bags, papers and smaller debris on the walls of the filter elements significantly impairs the filtering capacity of the devices, and can even render them practically inoperative. In these situations it becomes necessary to interrupt the filtration of the rainwater flow for cleaning or replacing the filter element.

[010] However, corrective measures partially solve the problem, as the debris that is deposited on the filter elements in the initial period of rain will remain there until the end of precipitation, compromising the filtering capacity of the filtering devices.

[01 1] In these situations, if the accumulation of debris deposited on the filter elements is very large, there will be a serious compromise in the filtering capacity of the rainwater filtering devices.

[012] A solution to this problem in the prior art is to discard the flow of rainwater to clean the filter elements. The disadvantage of this solution is that it wastes the water flow that has been diverted, which could not be filtered.

[013] A possibility to avoid this loss, also detected in the previous techniques, is the provision of reservoirs for temporary storage of the rainwater flow, while the filter elements of the filtering devices are being cleaned.

[014] However, in addition to increasing the cost of installing the collection system, the provision of such reservoirs could also cause problems. The storage of rainwater in these reservoirs would facilitate the decantation of debris at the bottom, which, over time, would tend to decrease the storage capacity. The possibility of organic contaminants, such as animal remains and dead insects, also accumulating on the bottom, which would be undesirable, should also be mentioned.

[015] Another alternative detected for the problem is to use multiple filtering devices, oversizing the project in such a way that the momentary insufficiency of one of them does not impair the filtering capacity of the rainwater filtering system. [016] The disadvantage of these proposals is the increased cost of installing multiple filtering devices, and the recurrence of the need for periodic cleaning of filter elements.

[017] Some solutions to these problems mentioned above were proposed by means of patent applications owned by the depositor of the present application: “Classified filter and separator of rainwater collected” (PI0805562-9); “Separator filter and adapter to the volume of rainwater ”(PI1016275-5);“ Rainwater separator and classifier system (PI1004676-3); and “Self-cleaning filtering device adaptable to the volume of rainwater” (BR202015016115-3) ”.

[018] The “Classified filter and separator of rainwater collected” (PI0805562-9) has the function of eliminating cloudy water and does not have a filter itself.

[019] The order PI1004676-3, in addition to eliminating cloudy and acidic waters, is adaptable to current meteorological needs, being able to maintain its yields in variations in intensity of precipitation.

[020] Order PI1016275-5 consists of a filter element divided into three parts, two flexible parts connected to the central part (semi-rigid) and which is connected by a rod to the top of the structure, is also capable of maintaining its performance in the variations in precipitation intensity.

[021] The order BR202015016115-3 has improved its functionality with the reduction of costs, being made up of a single filter element, which is completely flexible and suspended by mobile cables. This characteristic increases its mobility and variety in the types of movement, responding faster to variations in the flow of water captured, which results in a greater and faster filtration of the water captured and expulsion of debris. BACKGROUND OF THE INVENTION

[022] The “system for the classification and total filtration of rainwater collected” denotes inventive solutions to problems still persisting in the proposals of the aforementioned orders of the same title (PI1016275-5; BR202015016115-3; PI1004676-3). New features that translate as advantages capable of deflecting cloudy and / or contaminated water before it comes in contact with the filter itself and make full use of clean rainwater. Its inventive technical characteristics allow it to fully adapt to the flow of captured water and do not need the constant flow of rainwater to self-clean the filter element. In addition, it does not need adjustment in its filter element as in the cited patents.

[023] The objects revealed in the invention orders PI1004676-3 and PI0805562-9 were provided by a special sector with a set of components for the measurement of turbidity, consisting of a network of pipes, various connections, valves for directing the flow of dirty water and for the flow of clean water, sighs, electronic parts, among others. For this reason, they needed more physical space for assembly and, as a result, a higher cost.

[024] Orders PI1004676-3 and PI0805562-9 have differences in their methodology, but they are capable of meeting the various other market conditions.

[025] The device responsible for the analysis and water classification of the “rainwater separator and classifier system” (PI1004676-3) is provided downstream of the filter element. As a result, the first rainwater that may be cloudy and / or acid passes through the filter medium first, being able to damage it more quickly and interfere with the proper functioning of the system.

[026] The objects revealed in PI1016275-5, BR202015016115-3 and PI1004676-3 waste a percentage of water for self-cleaning. They are regulated to meet a specific rate of rain. This regulation has the function of fulfilling a cycle, for example, that starts with a light rain, rises to moderate and reaches a storm, closing the cycle with the same light rain. In this cycle, the devices revealed above filter and eliminate debris from a certain catchment area. However, there will be a point between the inclination of the filter element and a certain flow of water to eliminate the debris that generates more water waste.

[027] Objectives and advantages that the “system of classification and total filtration of rainwater collected”, object of the present invention, are proposed to achieve are listed below:

- be more efficient and economically viable since it requires fewer components, resulting in a more versatile and smaller equipment, making it possible to adapt it to a greater number of scenarios: commercial or residential, with more or less intensity of precipitation, more or less exposed to debris and dirt;

- eliminate the possibility of water accumulation in the pipes, as it does not use valves but other means of maneuvering water flows;

- protect the filter element, increasing its durability;

- record more information about the type of water, resulting in more accurate classification;

- do not need water to clean the filter element.

[028] This system can be used both in the collection of rainwater and in other situations such as in the treatment of water sources and processes of reuse of water in industries, etc.

DETAILED DESCRIPTION OF THE INVENTION

[047] The “system for the classification and total filtration of captured rainwater” (100), the object of the present invention, was developed based on research that aimed mainly at providing an efficient means of recycling rainwater and that would overcome all the problems detected in the prior art.

[048] The “total system” (100) can be better understood from the description of its internal components, which are revealed by means of Figure 1. These components are arranged in an initial arrangement, in standby mode, and able to start the filtration process as soon as a first rain (200) is collected by a catchment surface (201) and conducted through a supply duct (202) into the “total system” (100). [049] The “total system” (100) consists basically of a main body (10), such as a box capable of containing all the other components of the “total system” (100) and the lower internal portion of the main body ( 10) still be able to collect the water that has gone through the filtration process.

[050] A rainwater inlet device (20) is attached to the upper part of the main body (10). The inlet device (20) transposes said main body (10) through its upper portion (10 '), giving access to the water collected by the catchment surface (201). Said water is conducted through the supply duct (202) into the “total system” (100) to start the classification and filtering process.

[051] Downstream of the input device (20) it is connected to a filtering device (30), followed immediately by a rotating device (40). This is connected to a waste duct (50).

[052] The lower portion of the main body (10) houses a catchment chamber (11), which is provided with at least one discharge duct (12) of clean water.

[053] Data is collected by the input device (20) and the filtering device (30) and sent by wires or electromagnetic waves to a control module (60), which after processing generates control signals for the rotating device (40) .

[054] The details of the devices will be better described below, in summary to the description of the operation of the “total system” (100).

[055] The filtering process begins when rain (200) precipitates on the catchment surface (201) and mixes with dust. This cloudy water (200 ’) flows through the supply duct (202), being directed to the inlet device (20).

[056] Said inlet device (20) consists of an inlet duct (21), sized to support the volume of water directed by the catchment surface (201). The inlet duct (21) is preferably provided in its interior wall with at least one reading chamber (22).

[057] The reading chamber (22) is better detailed in the image in Figure 8. The said chamber consists of a channel (23), aligned with the flow of water and open at both ends. The channel (23) adjoins the inner wall of the inlet duct (21). The entrance (23 ') of the channel (23) is preferably chamfered and provided with a screen (24) capable of deflecting larger debris that may come carried by the first water flows at the beginning of a precipitation. The water outlet flow from the reading chamber (22) is at least 10% less than the water flow inlet flow.

[058] The interior of the reading chamber (22) is provided with a water presence sensor (25 ”’) and at least one more sensor capable of registering one of the following functions: direct light detection; detection of scattered light; conductivity detection; PH detection, generally employing the following sensors:

- optical sensor (25) of direct light;

- optical sensor (25 ') of scattered light;

- conductivity sensor (25 ”);

- and alternatively electrochemical and PH sensors (not shown) can be added.

[059] The optical sensor of direct light (25) and the optical sensor of scattered light (25 ’) are capable of providing data for the analysis of water turbidity. Said sensors can be applied independently or together.

[060] The optical sensor of direct light (25) provides a photoreceptor arranged to capture light radiation directly from the light source, while the optical sensor of scattered light (25 ') the photoreceptor is arranged in order to capture radiation scattered. When opting for the application of both types, there is a significant increase in the accuracy of the measurement. [061] The conductivity sensor (25 ”) measures the total concentration of salts dissolved in the water. Nowadays samples with conductivity equal to 100 pS / cm have been considered totally polluted. Conductivity data also allows to evaluate the acidity of the water, which represents more possibilities of classifications / selections of the water that is being collected and the determination of which will be directed for use.

[062] Some current sensors allow to perform different functions simultaneously, in order to alternatively allow the accumulation of functions, and consequently the reduction of the number of sensors in the detection of the data necessary to classify the water.

[063] In this way, the data obtained preferably through the sensors referring to the presence of water, the degree of water turbidity, and its conductivity are sent to the control module (60). The water presence signal activates the “total system” (100). Once activated, the other data will be compared with predetermined values, and from them the control module (60) will start the operation of the rotating device (40) and the filtering and water classification.

[064] The first water flows, due to their small volume and as can be seen in Figure 1, will pass entirely inside the reading chamber (22) and will continue to descend along the rest of the input device (20) passing by the centering ring (26).

[065] Said centralizing ring (26) directs the small initial flow of rain that flowed from the reading chamber (22) so that it leaves centrally from the lower end (27) of the input device (20), and thereby go through the entire filtering device (30), which is fully aligned vertically, still in its initial disposition. After passing through the filtering device (30), without reaching its walls and internal components, the first flow of water penetrates directly into the rotating device (40). [066] The centering ring (26), better detailed in the images of Figures 9 and 10, is a tapered component whose conical wall is formed by at least three adjacent (26 ') and flexible sections, held together only by the upper edges ( 26 ”). In this way, the adjacent sections (26 ') can flex, increasing the distance between them in order to allow the passage of debris larger than its smaller diameter (26 ”'), or larger water flows, resuming its configuration taper after the passage of debris or reduced water flow.

[067] The water that left the lower end (27) of the inlet device (20) passes through the center of the filtering device (30), without reaching its components, as shown in Figure 1, and directly reaches the rotating device (40) , being then directed to the discharge duct (50), and from this outside the “total system”

(100).

[068] Said rotating device (40) is basically formed by an inlet nozzle (40 '), initially aligned to the lower end (27) of the inlet device (20), and consequently to the vertical axis of the filtering device (30) - Figure 1 - and the lower end of it is fixed by a rotating coupling (43). A conductive body (40 ”) of the rotary control (40), consisting of a duct that connects the inlet nozzle (40 ') to an outlet nozzle (40”'), this nozzle being aligned with the central vertical axis (G) from the “total system” (100) and misaligned to the lower end (27) of the input device (20).

[069] The rotating device (40) is connected to an actuator (42) by means of transmission (41), which can be gears, belts, transmission shaft or some other existing in the technique, capable of rotating said device rotating (40) around the G axis, which passes through the center of the outlet nozzle (40 ”'). Said actuator (42) is managed by signals emitted by the control module (60).

[070] The outlet nozzle (40 ”') is attached by means of a rotating coupling (44) to the upper end of the waste duct (50). [071] When the “total system” (100) is in standby mode, the arrangement of the internal components - Figure 1 - is presented with the filtering device (30) in a rectilinear tubular configuration, aligned between the lower end ( 27) of the input device (20) and the input nozzle (40 ') of the rotating device (40), with the direction of alignment parallel to the central vertical axis (G).

[072] But as the turbidity of the water has decreased, this rectilinear configuration changes so that the filtering element of the filtering device (30) effectively starts its action.

[073] This is possible, as the filtering device (30) consists of a resilient duct (31), with a flexible and porous wall, capable of expanding and contracting like a bellows, allowing it to adopt varied curvilinear configurations when its fixations, at the lower end (27) and inlet nozzle (40 '), they are subjected to misalignment. Consequently, the resilient duct (31) intercepts the downward water flow, filtering it.

[074] The resilient duct (31) can preferably consist, for example, of a spiral steel or polymer structure, covered by a filtering fabric or canvas, the porosity of which must be of the order of magnitude of the smallest aggregates of particles to be retained . It is recommended that the fabric used as a filter medium is a fabric with multifilaments, which allows little penetration of solids in the mesh interstices.

[075] Alternatively the resilient duct (31) can be made exclusively of polymeric material, with a flexible and porous wall, capable of expanding and contracting like a bellows.

[076] The filtering device (30) also includes at least one optical sensor (32) on the inner wall of the resilient duct (31), whose data readings are also sent to the control module (60). [077] The said optical sensor monitors the concentration of a certain amount of debris that may be trapped in the internal wall of the resilient duct (31) during the filtration of water from a rain cycle. The performance of the optical sensor (32) will be better explained, later, during the description of the operating cycles of the “total system” (100).

[078] Figure 1 revealed the “total system” (100) with its internal components arranged in the waiting position, and the first rainwater beginning to descend from the catchment surface (201). This water flows inside the reading chamber (22), which due to the water presence sensor (25 '”) activates the“ total system ”(100), and begins to generate data when passing through the direct light optical sensors ( 25) and scattered light (25 ') and the conductivity sensor (25 ”).

[079] The reading chamber (22) may alternatively be positioned in the discharge duct (50), operating in the same way.

[080] The data is sent to the control module (60), and using a pre-recorded algorithm, it classifies the rain water (201) that has mixed with the dust as cloudy water (201 ') and, with this, does not drive the actuator (42).

[081] Other incompatible classifications and possible to be detected by the combination of data generated by the optical sensors of direct light (25) and scattered light (25 '), electrochemical sensor and the conductivity sensor (25 ”), such as for example acidic water, can be pre-programmed in the control module (60). Thus, the resilient duct (31) would also remain in a vertical position as long as the water does not reach a pre-selected classification, as can be seen in figure 1.

[082] The flow of water declassified by some pre-established parameter has its course centralized by the centralizing ring (26) after leaving the reading chamber (22), and thus passes through the filtering device (30) without reaching its interior wall, as shown in Figure 1. Next, it reaches the rotating device (40), being directed to the disposal duct (50), and from there outside the “total system” (100) for disposal purposes.

[083] When the declassified water stops passing through the filter element (31) of the filtering device (30), the wefts are preserved from the excess suspended impurities present in the first water flows, and thus have a significantly increased useful life, since this low flow of initial water generally carries a high concentration of micro impurities capable of contaminating filter elements more quickly.

[084] The high degree of contamination carried by the first water flow is not restricted to physical impurities, but also pathogenic, which even after mechanical filtering if mixed with reused waters would require a more intense and more expensive treatment of the accumulated water, depending on the purpose of consumption.

[085] However, when the rainwater flow (201) that passes through the rainwater collection system (102) is within the pre-programmed classification, the control module (60) acts by sending a signal so that the actuator (42) is actuated.

[086] Figure 2 reveals the “total system” (100) with its internal components arranged according to this second stage of action: moving from the waiting state to the operating state.

[087] The control module (60) sends a signal to the actuator (42) so that it activates the transmission medium (41), promoting rotation of the rotating device (40) and consequently a misalignment between the inlet nozzle (40 ' ) and the lower end (27) of the input device (20).

[088] Misalignment causes the initial rectilinear tubular configuration of the filtering device to change (30), causing the resilient duct (31) to begin to show a curvilinear configuration. The curvilinear shape of the resilient duct (31) starts to capture the flow of water from the inlet device (20).

[089] The water starts to be filtered through the resilient duct wall (31), falling directly into the catchment chamber (11) of the lower portion of the main body (10), and then drains through the discharge duct (12) of clean water .

[090] At this stage of operation, the “total system” (100) can still allow the discharge of a small percentage of water through the waste duct (50).

[091] Figure 3 reveals the “total system” (100) with its internal components arranged according to a third moment of operation: state of final operation.

[092] At this stage the actuator (42) took the rotating device (40) to the position where the inlet nozzle (40 ') and the lower end (27) of the inlet device (20) have the largest possible horizontal spacing within the main body structure (10), consequently the resilient duct (31) will be at its maximum extension and the largest filtration area available to receive large volumes of water.

[093] It should be noted that only when a rain reaches a degree of storm, large or very large debris begins to be dragged from the catchment surface (201) and guided through the supply duct (202) into the “total system” (100).

[094] These larger debris are able to pass through the centralizing ring (26), due to the ability of the adjacent sections (26 ') to flex until they are parallel to the internal walls of the inlet duct (21). These debris end up trapped by the resilient duct (31). The accumulation of debris forces the formation of a larger curvilinear loop in the resilient duct (31), since its flexible wall is able to expand and contract like a bellows. This scenario is revealed through Figure 4. [095] Thus, Figure 4 reveals the “total system” (100) with its internal components arranged according to a fourth moment of operation: state of operation with excess of large debris retained.

[096] The “total system” (100) continues to operate at the same level of performance, but excessive accumulation of large debris, such as leaves, can interfere with efficiency. For this reason, optical sensors (32) were provided on the inner wall of the duct (31), which are continuously sending data to the control module.

(60).

[097] When the data from the optical sensors (32) reaches a predetermined value in the configuration of the control module (60), it will start a debris cleaning cycle.

[098] This cycle begins when the signal module (60) sends the signal to the actuator (42), so that it activates the transmission medium (41), promoting rotation of the rotating device (40) in the opposite direction to the and consequently the realignment between the inlet nozzle (40 ') and the lower end (27).

[099] Thus, Figure 5 reveals the “total system” (100) with its internal components arranged according to a fifth stage of operation: cleaning operation.

[0100] When the “total system” (100) returns to its initial configuration, even for brief seconds, the resilient duct (31) returns to a vertical straight tubular configuration and aligned parallel to the central vertical axis (G), releasing the larger residues to be discharged through the disposal duct (50). Even if some residual residue tends to get stuck inside the resilient duct (31), the large flow of water is able to drag it out.

[0101] The cleaning cycle execution time can be differentiated according to the flow volume information, generated by the reading chamber (22) and processed in the control module (60). [0102] Alternatively, the control module (60) can also promote, in a pre-programmed way during the discharge of larger debris, a rapid back and forth movement of the rotating device (40) and, consequently, of the resilient duct (31) , when it is in the vertical straight tubular configuration of the cleaning cycle, to ensure the release of all major debris.

[0103] After the cleaning cycle revealed by Figure 5, the “total system” (100) returns to its operating configuration, as revealed by Figure 6, until the reading chamber (22) stops detecting the presence of water. At this point, the “total system” (100) returns to presenting its internal components arranged in a waiting state, as shown in Figure 7.

[0104] When choosing to manufacture the resilient duct (31) with material of lower resilience, it may be necessary to provide an auxiliary return device (70) alternatively - Figure 7.

[0105] Said return device consists of a cable (71) that has one end attached to the middle portion of the resilient duct (31), a pair of guides (72), preferably affixed to the internal wall of the main body (10 ), which direct the other end of the cable (71) to the lower end of the rotating device (40), so that the other end of the cable (71) goes around its outer wall, being rolled up or unrolled following the turning movement of said lower end of the rotating device (40).

[0106] In this way the return device (70) assists the recovery of the vertical straight tubular configuration of the filtering device (30), so that the lower end (27) of the inlet device (20) and the inlet nozzle (40 ' ) of the rotating device (40) are aligned.

[0107] Alternatively, other applications can be added to the functions of the control module (60), which can use “wireless” technology to interconnect and interact with mobile devices. Thus, dedicated applications can be used to receive all the information of the “total system” (100), such as: the moments of beginning and end of the rain, the classification of the flowing water, the amount of water captured, the amount of times that there was a need for cleaning, system failures such as power outages, among other information. In addition, the application can command and reprogram the operating parameters of the command module algorithm (60).

[0108] Information on the quantity of water captured is monitored through a water flow sensor (not shown in the figures), which can be installed at the water inlet or outlet. It monitors with the control module (60) the amount of water captured in a given time.

[0109] The “total system” (100) is a new technology that aims to evolve in the capture and filtering of rainwater. As demonstrated in the explanations above, there is a great advantage of the state of the art over existing filters.

[01 10] One of the main factors that makes the proposal now presented viable is the elimination of several problems, previously mentioned.

[01 1 1] One of these problems is the rapid contamination of the filter element due to the passage of the first rainwater with a large load of dust particles, clay, degraded biological material and all kinds of micro debris accumulated in the catchment areas during the period without rain. These infinite types of micro particles are capable of drastically reducing the useful life of the filter element of rain catchers on the market at each first flow of each precipitated rain.

[01 12] Another unquestionable advantage of the proposed invention is its self-cleaning ability, eliminating large debris that is only dragged when the volume rainfall is very large. In large storms, debris is usually dragged from the catchment area and clog the existing rain catchers, and the current proposal also overcomes this problem.

[01 13] The invention has been described herein with reference to its preferred embodiments. It should, however, be made clear that the invention is not limited to these embodiments, and those skilled in the art will immediately realize that changes and substitutions can be adopted without evading the inventive concept described here.

[01 14] Modifications can be introduced in the present invention without, however, departing from the inventive concept of the invention, such as, for example, the application in water treatment processes of springs such as rivers, lakes, among others and in the processes of treatment in industries.

[01 15] Thus, some components can be arranged in different positions from those shown in the drawings, or from the suggested construction alternatives, without changing the concept of the present invention, being limited only to the content of the claims that follow.
