EA041622B1 - DEVICE AND METHOD FOR FILTERING FLUID CIRCULATED IN WATER SUPPLY AND HEATING SYSTEM - Google Patents

Description

The invention relates to a device and method for filtering fluid circulating in a plumbing and heating system.

The invention is advantageously applied to water installations for temperature control and/or domestic hot water supply in residential, commercial or industrial type buildings.

Heating systems or domestic hot water systems circulate a fluid, usually water, that circulates through the various components of the system (pipes, boiler, pump, valves, radiator elements, utilities, etc.).

In such systems, it is well known to use filters suitable to keep the circulating fluid as clean as possible, i.e. free of impurities such as dirt, sand, contaminants, etc. This is because these impurities circulating within the system can cause blockages, failures in certain components, in particular the boiler and valves, and generally reduce the performance of various components and reduce overall efficiency.

It is especially important to remove iron particles from various impurities, which are usually released by system components such as pipes and radiant elements (for example, heaters and radiators), as they can cause breakages inside boiler elements or break system lines.

Typically, filters are installed between a pipeline carrying fluid back from the system, which is usually filled with impurities and iron particles, and a pipeline carrying fluid to a central heating boiler (or heat pump). In this way, the filter can act on the supply to the central heating boiler, i.e. in front of it, by sending a fluid that is filtered and cleaned of impurities.

Typically, known filters can be installed along any fluid conduit to cross it, filter out, and continue down the channel.

In the technical field, such filters are often referred to as dirt separators due to their function of removing impurities.

It is also known to allow the filter to be opened to perform periodic maintenance tasks and in particular to remove impurities collected by the filter or to replace filter elements.

One known type of filter involves both the use of mesh filter elements, which trap impurities such as sand and dirt, and the use of magnetic type filter elements, which allow the separation of iron particles from the fluid in transit by attracting the particles and keeping the particles in contact with the magnetic field. element.

Conventionally, known types of filters have a fluid inlet and a fluid outlet; the conduit (upstream of the filter) carrying the fluid to be filtered is connected to the inlet of the filter, and the outlet of the filter, in turn, is connected to a subsequent conduit (downstream of the filter), so that the filtered fluid will continue its path in the system. The inlet carries the fluid to the central part of the inner filter chamber where mechanical filtration takes place, and from this central part the fluid passes to the more outer part, circumferentially surrounding the central part, of the filter chamber, from which the fluid is then directed to the filter outlet, which directs the filtered fluid into the pipeline to continue its journey through the system. At the bottom of the filter, under the central part of the chamber, there is a drain cock to remove impurities filtered by the filter. Mechanical filtration is usually performed using a filter element located in the central part of the chamber and consisting of a grid wound around itself several times to form a cylindrical body.

Cyclone filters are also known which instead have a tangential inlet and an axial outlet. Such filters use the centrifugal force of the water that flows tangentially, which causes the separation of sand and other particles that hit the filter wall and fall down where they are collected and can be removed, while the water spirals down and then rises into axial direction, towards the center of the filter, before the outlet.

The Applicant has found that the known solutions described above are not without drawbacks and various aspects of them can be improved.

First of all, the known solutions can only work correctly when the inlet is connected to a pipeline carrying the fluid to be treated and the outlet is connected to a pipeline downstream of the filter. This is due to the fact that known solutions always lead to a mandatory and irreversible path of the fluid to be treated, which in the case of mesh filter elements goes from the inlet to the central part of the inner chamber, and then passes into the outermost annular part, and from there to the outlet, whereas in the case of cyclonic filtration it goes from the tangential inlet at the outermost part of the chamber, and then passes to the central part, and from there towards the outlet.

This means that if the inlet and outlet connection of the filter with pipelines downstream and upstream of the filter itself is made in the opposite way, the filter will not be able to work.

In fact, the known filters only work effectively in one configuration and the installation must be carried out with respect to the exact direction of flow; for this reason, there are arrows on the inlets and outlets to indicate the mounting direction.

In addition, the known solutions run the risk of clogging the filter element (cylindrical grid) that controls the mechanical filtration due to non-optimal use of the flows circulating inside the filter chamber. Clogging can result in loss of flow through the filter or cause complete blockage.

In addition, known filters cannot provide efficient solutions in terms of assembly, access and maintenance for all different installation conditions and different types of heating systems.

In this situation, the object, which is the basis of the present invention in its various aspects and/or embodiments, is to provide a fluid filtration device and method that can eliminate one or more of the above disadvantages.

Yet another object of the present invention is to provide a device and method capable of effectively filtering fluid circulating in a plumbing and heating system.

In the drawings, the fluid filtration device according to the present invention is generally indicated by the reference number 1. As a rule, the same reference number is used for the same or similar elements, possibly in embodiments.

The device 1 is designed to filter the fluid, usually water, circulating inside the plumbing and heating system, usually containing pipes and channels, valves, a boiler or power generator, pumps, radiating elements (heaters, radiators, floor coils, etc.). ), communications, etc.

In the drawings, the system for which the device is intended is not shown or disclosed in detail, since it is known per se in the technical field of the present invention.

Preferably, the filtering device is designed to be installed in series with the heating system pipeline to intercept and filter the fluid flow, such installation successively results in shutting off the pipeline and accommodating a device that restores the fluid flow in the pipeline itself. The conduit intersection defines a conduit upstream of the device that sends incoming fluid to the device and a conduit downstream of the device that receives the exiting filtered fluid from the device.

The device 1 comprises, first of all, a housing 2 forming within itself a filter chamber 3 intended for passing through it the fluid to be filtered. The housing 2 is provided with an inlet/outlet joint 10 configured to allow fluid to enter and exit from said filter chamber 3.

Preferably , the filter elements 40 comprise at least one filter element 41 configured to perform mechanical separation of substances and solids present in the fluid to be treated from the fluid in which they are suspended. The filter element 41 is located inside the filter chamber 3 so as to divide it into the first half-chamber 8 and the second half-chamber 9, and so that the fluid passing in the filter chamber passes through the filter element to pass from the first half-chamber 8 to the second half-chamber 9 or vice versa.

Preferably, the first half-chamber 8 is in fluid communication, without passing through the filter element 41, only with the first inlet/outlet 11, while the second half-chamber 9 is in fluid communication, without passing through the filter element 41, only with the second inlet/outlet hole 12.

The device further comprises a connection module 30 which can be mounted, preferably in a removable or reversible manner, on the body 2 of the device.

The connection module 30 comprises a first inlet/outlet conduit 31 connected to a heating system pipe to receive from there or to direct into it a fluid entering or leaving said device body, and a second inlet/outlet conduit 32 connected to a corresponding heating pipe. systems to direct into it or receive from it a fluid exiting from the specified body of the device or entering it.

The connection module 30 further comprises a connection joint 33 configured for selective bonding, in accordance with a plurality of operating configurations, with said inlet/outlet joint 10 of the device body 2.

Connection module 30 contains:

a first passage section 34 formed on a portion of said joint 33 in fluid communication with said first inlet/outlet conduit 31;

a second passage section 35 formed at a corresponding portion of said joint 33 and distinct and separate from the first passage section 34, in fluid communication with said second inlet/outlet conduit 32.

The device according to the present invention provides that the connection module 30 can be selectively installed on the housing 2 in accordance with a variety of different operating configurations. This set of operating configurations includes at least a first operating configuration, in which the connecting module 30 and the device body 2 have a first mutual arrangement that determines the correspondence of the first passage section with at least one part of the first inlet/outlet of the body device, with the fluid connection of the first inlet/outlet pipeline exclusively with the first semi-chamber, and the correspondence of the second passage section 35 with at least one part of the second inlet/outlet opening 12 of the body 2, with the fluid connection of the second inlet/outlet pipeline 32 exclusively with the second semi-chamber 9;

a second operating configuration, in which the connection module 30 and the housing 2 have a second relative position, which determines the correspondence of the first passage section 24 with at least one corresponding part of the first inlet/outlet 11 (at least partially different from the first working configuration part) of the housing 2, with the first inlet/outlet conduit 31 in fluid communication with the first half-chamber 8 exclusively, and the second port section 35 corresponding with at least one corresponding part of the second inlet/outlet 12 (at least partially different from the first working configuration part) housing 2, with a fluid connection of the second inlet/outlet pipeline 32 exclusively with the second semi-chamber 9;

Preferably, the transition between the first and second operating configurations causes the connection module to rotate relative to the device body. Preferably, the plurality of operating configurations include a third operating configuration, in which connection module 30 and housing 2 have a third relationship that defines:

correspondence of the first passage section 34 with at least one corresponding part of the second inlet/outlet 12 of the housing 2, with the first inlet/outlet pipeline 31 in fluid connection exclusively with the second semi-chamber 9, and the correspondence of the second passage section 35 with at least one corresponding a part of the first inlet/outlet 11 of the body 2, with the second inlet/outlet conduit 32 in fluid communication with the first semi-chamber 8;

Preferably, the transition between the third and fourth operating configurations results in a corresponding (mutual) rotation of the connection module relative to the device body.

As such, it is preferred that the connection module (which connects to and traverses the pipes carrying the flow of the fluid to be filtered) can be mutually mounted to the body 2 (where the filtration takes place) in four different operating configurations, for example based on the orientation and direction of the pipes . Thus, it is possible to properly orient the connection module, keeping the position of the housing 2 unchanged, which is usually positioned so that the filter chamber is vertical and the bottom of this chamber is in the lower position, as will be shown below and as shown in the accompanying drawings.

In each configuration, the flow enters from one of the two pipelines of the connection module, passes through the corresponding port section and from there passes into one of the two inlet/outlet ports, and then into one of the two half-chambers; the flow then passes through the filter element and begins an exhaust path that passes from another half-chamber, passes through another inlet/outlet, another passage section and another pipeline of the connecting module, from which the filtered fluid exits the device to continue its path in the plumbing pipe and heating system.

The design and operation of the device is completely symmetrical, so that filtration is effective regardless of which of the two pipelines of the connecting module is used for fluid inlet and which for fluid outlet, and therefore which of the two chambers the fluid to be filtered enters, and into which filtered fluid (i.e., the side of the filter element where filtration occurs).

Preferably, in the second operating configuration, the dividing segment 23 is located on and aligned with said second diameter 39 of the dividing zone 37;

the transition from the second to the third working configuration is carried out with a rotation of 90° in the first direction around the joint axis 16, and the transition from the third to the second working configuration is carried out with a rotation of 90° in the second direction; it should be noted that between the two configurations (mutually rotated) there is a change of paths, the first passage section 34 passes from communication with the first inlet/outlet 11 to communication with the second inlet/outlet 12 (and vice versa), and the second passage section 35 passes from communicating with the second inlet/outlet 12 to communicating with the first inlet/outlet 11 (and vice versa).

It should be noted that, preferably in various operating configurations, the orientation of the connector module is changed (which can be rotated as needed), while the housing 2 is always vertical to allow the filtered material to be emptied (and subsequently removed, discussed below).

By vertical arrangement is meant the orientation of the body of the device (and in particular the filter chamber) in accordance with the vertical axis facing the floor of the installation site.

It should be noted that, in addition, each different mutual rotation between the connection module and the body of the device determines the corresponding operating configuration; in other words, the mutual rotation between the connection module and the body of the device, preferably occurring continuously rather than discontinuously, through a plurality of operating configurations, of which the first, second, third and fourth operating configurations constitute a subset (associated with predetermined rotation angles). The only condition for determining a properly functioning working configuration is that the first section and the port section do not overlap the separating segment, i.e. are not simultaneously at both the first inlet/outlet port and the second inlet/outlet port and are not in fluid communication with them. In fact, as disclosed above, in each operating configuration, the first port section communicates with only one of the first inlet/outlet port and the second inlet/outlet port, and the second port section communicates with only the other of the first inlet/outlet port and the second inlet/outlet port. . Thus, there is no possibility of mixing or passing of fluid between the streams associated with the first and second inlet/outlet pipelines, and the fluid always follows the correct path inside the filter chamber of the device body; the passage between the first and second inlet/outlet pipelines occurs only through two semi-chambers and through the filter element.

Preferably, the second parts of the first 31 and the second inlet/outlet pipeline 32 are coaxial and lie on the same axis of the installation of the device.

Preferably, this axis of the plant is designed, under the condition of assembling the filtering device in series with the pipes of the heating system, to intercept the flow of the fluid and carry out filtration in it in order to coincide with the longitudinal axis of such pipes.

It should be noted that the serial assembly results in a pipeline interruption and the creation of two pipes upstream and downstream of the device, which must be connected to the first and second inlet/outlet pipeline (depending on the desired conditions of use).

Preferably, the first 31 and the second inlet/outlet conduit 32 are structurally identical to each other. Preferably, the connection module 30 is symmetrical about

- 10 041622 plane of symmetry passing through the central axis 36. Preferably, the plane of symmetry divides the connecting module into two identical halves, each of which contains a respective inlet/outlet pipeline (31; 32);

the corresponding half of the connecting joint 33;

corresponding half of the dividing zone 37.

The symmetry allows you to always have the correct connections in every working configuration and with every rotation of the connection module, while maintaining the mounting of the connection module to the device body.

Preferably, said operating configurations cause fluid to pass through the filter wall 41 from the first side 43 to the second side 44 as the fluid enters the device body 2 through the first inlet/outlet 11 (which is therefore an inlet) and exits body 2 of the device through the second inlet/outlet 12 (which is therefore an outlet).

Preferably, said operating configurations cause fluid to pass through the filter wall 41 from the second side 44 to the first side 43 as the fluid enters the device body 2 through the second inlet/outlet 12 (which therefore represents

Preferably, the device 1 can operate correctly (i.e., filter the fluid) in each of the mentioned operating configurations, as in the case when the fluid enters the device from the first inlet/outlet conduit 31 and exits the device through the second inlet/outlet conduit 32 , and in the opposite case, when the fluid enters the device from the second inlet/outlet pipeline 32 and exits the device from the first inlet/outlet pipeline 31.

Preferably, the filter wall 41 is located longitudinally between the bottom surface 3C and the inlet/outlet joint 10.

Preferably, the filter wall 41 has two major dimensions in its extension plane and a third reduced dimension perpendicular to the extension plane, in which these two major dimensions represent the height of the filter barrier along the direction coinciding with the direction of the axis of the longitudinal extension 2A of the housing 2 and the width of the filter barrier in the direction , perpendicular to the axis of the longitudinal extent of the hull.

Preferably, under conditions of use of the device in which the first 31 and the second inlet/outlet duct 32 of the connection module 30 are connected to pipes of the heating system that run vertically (for example, along a vertical wall), the first part 4A is designed to be placed horizontally, and the second part 4C is designed to be placed vertically and below the first part.

In one possible alternative embodiment (not shown), the upper end of the filter element may coincide with the separating segment, and the filter element extends from the inlet/outlet junction to the bottom of the device housing. In this case, there is no dividing wall, and all division of the filter chamber into the first and second half-chambers is carried out by the filter element.

In an alternate embodiment not shown, the magnetic filter may be placed directly within the filter chamber.

This can be done by removing the first cap 55 of the first magnetic filter and moving it into the desired housing 52 or 82.

Preferably, when the first magnetic filter 50 is associated with the first hollow projection 51, it magnetically filters the fluid passing in the first half-chamber 8, while when the first magnetic filter 50 is associated with the second hollow projection 81, it magnetically filters the fluid passing into second semi-chamber 9. Essentially, the device may contain two

- 14 041622 hollow protrusions and only one magnetic filter 50, which can be selectively inserted into the first housing 52 or the second housing 82. In both cases, since the operating configurations always allow the passage of fluid between two subchambers (and always passage through the mechanical partition 41 ), magnetic filtering is guaranteed by at least the magnetic filter 50, regardless of the housing in which it is inserted.

In one possible embodiment, the filter elements 40 may further comprise a second magnetic filter 80 associated with the device body 2 and configured to trap and retain ferromagnetic substances and particles that are present in the fluid to be filtered, to separate the particles from the fluid passing through through the device.

In this alternative embodiment (not shown), the first magnetic filter comprises a collar housing configured to be removably mounted outside the device housing and one or more magnetic elements associated with the collar housing and configured to generate a constant magnetic field to act on the fluid passing through through the filter chamber, and retain ferromagnetic substances and particles present in the fluid within the filter chamber itself. Preferably, the collar body is in the form of a ring and is sized to enclose, at least in part, a portion of the outer side surface of the device body. Preferably, the annular shape of the collar body has a partial break along the circumferential extent of the ring, and the collar body can be removably mounted outside the device body by a snapping movement of the body itself, in the presence of said partial break. Preferably, the collar body is made of a material, such as plastic, which allows the collar body to resiliently deform during a snapping movement for assembly and disassembly from said device body. Preferably, the collar body has one or more sockets, each of which is adapted to receive, preferably in a removable manner, a respective magnetic element. Preferably, the first magnetic filter comprises two, three or more magnetic elements which are placed in the collar housing and arranged circumferentially around the collar housing, preferably at equal angular intervals. Preferably, the first magnetic filter is configured to retain substances and particles having ferromagnetic properties present in the fluid passing through the device on the side surface of the filter chamber, in particular on the part of the side surface corresponding to the collar body assembly position outside the device body. It should be noted that the collar magnetic filter can also be used in combination with the magnetic filter 50 (or also in combination with the magnetic filter 80) of the cartridge type to enhance the magnetic filtering effect. In fact, the collar magnetic filter is located externally around the body of the device, while the magnetic filters 50 or 80 of the cartridge type are inserted into the casing 52 or 82 formed by the projections 51 or 81 inside the filter chamber.

Preferably, the device may include a drain cock 90 configured to empty the filter chamber without dismantling the device from the system in which it is installed, without disconnecting the first and second inlet/outlet from their respective pipelines, and without dismantling the body of the device (in particular, the first half-shell 61 and second semi-body 62).

Preferably, the drain cock 90 is located at the drain hole 91 located on the bottom surface 3C of the device body 2 and allows the contents of the filter chamber 3 to be selectively emptied to perform cleaning or maintenance of the device.

Preferably, the drain hole 91 is located on the bottom surface, enclosing the bottom

- 15 041622 the end 47 of the filter partition 41 in such a way that it communicates laterally with both the first half-chamber 8 and the second half of the chamber 9, but without establishing communication between the first and second half-chambers.

Preferably, the drain hole 91 is located at the lower end of the sloping part of the bottom surface 3C, extending downward relative to the side surface, and this sloping part allows the filtered material inside the filter chamber, in particular due to the filter wall 41, to move to the drain hole under the action of gravity or decantation.

In addition, the sloping portion also allows material trapped and held by the magnetic filters on the inner surface of the protrusions in the filter chamber to move towards the drain (apparently after the magnetic filters have been removed).

Preferably, the drain cock 90 can operate selectively in a closed state, in which the drain hole 91 is blocked and does not allow the fluid to leave the filter chamber 3, or in an open state, in which the drain hole 91 is installed in communication with the outside of the device 1.

Preferably, the drain cock includes a removable safety cap 95 located downstream of the closure element 93 and configured, when placed in place, to close the drain opening even if the handle moves the closure element to the open state.

It should be noted that the drain cock is preferably configured, due to the arrangement of the drain hole, to draw in from both half-chambers 8 and 9 in order to ensure efficient draining of the filtered material and cleaning of both half-chambers. This is especially true because, as indicated above, depending on the operating configuration and the type of connection used for the inlet/outlet pipelines, the material can be filtered on the first side 43 or on the second side 44 of the filter partition 41, and then accumulate in the first semi-chamber 8 or in the second half-chamber 9. In each case, the drain cock 90 makes it easy to clean both half-chambers.
