FR2841235A1 - Device designed for water purification comprises section of pipework having open end with closing mechanism containing electrode assembly - Google Patents

Abstract

A closing mechanism has a smooth-walled butt end (31) and a ring fixing (32). The butt end is made from a single piece to form a cylindrical shaft (33) with an external diameter at least equal to the internal diameter of the open end of the pipework and a carrier (34) with an external perimeter at least equal to the pipework's external perimeter. A device for water purification comprises a pipework in which one section (2) has an open end (21) by which a closing mechanism (30) is engaged and held, such as a temporary valve or an assembly of at least two electrodes, each formed from a plate of electrically conducting material. The whole assembly is designated an electrode. The butt end is held in place against the pipework section by tightening it onto the ring fixing not onto the butt end, to allow some relative movement between the butt end and the fixing mechanism. The fixing mechanism can be pressed without inter-penetration against the fixed carrier which is in turn pressed externally against the end of the pipework section. The butt end is fixed to plates which are spaced apart and parallel to one another. These plates are electrically conductive and some of them have a frame around at least three sides. The electrical connection terminals extend externally from the central part of the carrier and remain accessible due to the annular shape of the fixing ring, which provides a central space. The plates are held together but electrically isolated from each other by insulating supports which belt them in. Each of these supports has two opposing racks to take two opposing sides of the plate. The fixing ring has a circular shoulder with an internal diameter less than that of the support.

Description

Cabinet DELAYE Water trapping device including an electrode

  removable The purification of water, especially in pool pools, requires the destruction of microorganisms, bacteria and others, which may be dangerous for the health of users. We know the elementary principle which consists simply of dissolving chlorine in the water circulating in a closed circuit, but this has the disadvantage of giving the water of the basin a strong unpleasant odor and of provoking very annoying irritations of the eyes.

mucous membranes and even skin.

  To avoid this, the principle of the formation of copper-silver ions has also been used by an electrolysis phenomenon using electrodes fed with direct current at low voltage, these ions having the effect of destroying the harmful living elements without releasing unpleasant odors. neither create physical gene. On the other hand, these same ions have the effect of revealing certain defects in the coating of synthetic materials which often covers the

basin walls.

  A third hybrid principle of the first two is to apply the principle of electrolysis even within the water after salt has been introduced, whereby hypochlorite is created in which the effect is carried out. similar to those of chlorine but without odor, the presence of hypochlorite being revealed only by a slightly

pond water.

  This method is known per se but it is concretized by more or more material elements.

less practical and effective.

  For example, the electrodes wind often difficult to handle even when they wind grouped into one compact assembly, especially because they must be connected to a current generator by flying conductors that require very good accessibility. In addition, erosion of the electrodes is inevitably occurring and these have to be replaced periodically, and this replacement is at present inconvenient because of the special attention which must be paid to the sealing and proper orientation of the electrodes.

  electrodes in relation to the flow direction of the water.

  The electrodes wind at least two wind and wind in a set that it names globally "electrode" in the singular although it is composed of a support that maintains several separate electrodes, each formed by a plate material driver. The plates are properly held together, but this complete "electrode" is inherently impractical when

  location ['electrode used and set up a new electrode.

  The present invention overcomes the known drawbacks by making it possible to clearly differentiate the support of the electrodes on the one hand, and the member which serves to maintain this support.

on the other hand.

  To this end, the subject of the invention is a device intended for the treatment of water with a view to its purification, of the type comprising a pipework of which a segment has an open end through which a closure member such as a temporary shutter or a set of at least two electrodes each constituted by a plate of electrically conductive material, together generally designated by << electrode >>, characterized in that the ferreting member comprises on the one hand a base and on the other hand an annular fixing member, and said base is smooth-walled and forms in a single piece: a cylindrical bore whose outer diameter is at most equal to the clearance, to the inner diameter of the open end of the pipe segment, a door whose outer perimeter is at least equal to the outer perimeter of the pipe segment, said base to be held in place on the pipe segment clamping on said segment the annular fastener not engaged with the base to allow relative movement between said base and fastening body, the latter to bear without interpenetration against the immobilized door, doore which is

  it is applied externally against the end of the pipe segment.

  The invention will be better understood from the detailed description given below with reference to

  drawing annex. Of course, the description and drawing is only given as an example

  indicative and not limitatiú Figure 1 is a schematic overview, showing the replacement of a

  electrode in a pool water circulation system.

  when replacing one electrode with another.

  Figures 9 - 10 show partial schematic views, respectively in section and elevation of a dummy electrode according to the invention, represented here in place of a

  true electrode, which is an abnormal situation.

  Referring to the drawing, there is a small portion of a swimming pool circulating installation comprising various devices such as pump, filter, etc. but of which only part of the piping composed of a vertical upstream segment 1 and a horizontal downstream segment 2 are shown here, these two segments carry an arrow F

  indicating the flow direction of the water they carry.

  The segment 1 has four radial passages provided with threaded ends 3, 4, 5 and 6 provided for different connections and connections: A on the thread of the end piece 3 is screwed a waterproof cap through an electrical wire 7 connected to a socket earth 8; On the thread of the nozzle 4, a waterproof cap is screwed around a sensor element 9 of a flow detector 10 which verifies that water effectively steals in the pipe segment 1, or on the contrary that there is has a lot of water, but there is no flow movement, that is, no flow; on the thread of the nozzle 5, a waterproof cap is screwed to a line 11 of a ph

  meter 12 which continuously measures the pH of the water circulating in segment 1.

  On the thread of the nozzle 6 is screwed a tight cap through a conduit 13 connected to a reservoir-dispenser 14 containing an acid / alkaline solution which is

  introduced into the water according to measurements taken by the ph meter 12.

  Segment 2 is perpendicular to segment 1 and its extremity 20 located on the right in FIG. 1 is connected to the piping of the installation which ends at the pool of the pool from which the water is treated. Its end 21 located on the left is freely open and has an external thread 22. By the open end 21, it must engage and hold in place a closure member

  to be placed across the passage constituted by the free internal section of segment 2.

  The closing member 30 is differently constituted according to the desired purpose mats, in any case, it comprises on the one hand a base 31 and on the other hand a ring fastener

here constitutes a ring 32.

  The base 31 has smooth walls and forms in one piece: a cylindrical bore 33 whose outer diameter is at most equal to the inner diameter of the pipe segment 2 so that it can be introduced axially into said segment 2, by the open end of the latter, with a slight jue, that is to say freely and without effort, A of a door 34 constitute a solid bottom and whose outer perimeter is at least

  equal to the outer perimeter of segment 2.

  Here, the door 34 is circular and its outside diameter is substantially equal to the diameter

  outer segment 2, the external thread 22 being considered negligible.

  When it was 33 is engaged in the segment 2, it must be maintained and we use the second part of the closure member, namely the fixing member that is the ring

ring finger 32.

  The fastener member has a cylindrical body 35 and a circular shoulder 36 which is annular and whose inside diameter is smaller than the inside diameter.

  34, the cylindrical body 35 carries a tapping 37.

  The tapping 37 is coordinated with the thread 22 so that both can cooperate when screwing the ring 32, which implies that the length of the cylindrical body 35 is greater than the thickness of the door 34, so that the tapping 37 can to reach the thread 22 although the door 34 is interposed between the end of the segment 2 and the inner face of the shoulder 36. In practice, the length of the cylindrical body 35 is equal to the sum of

  lengths 33 and 34 of the door (Figure 2).

  Here, the circular shoulder 36 has an outside diameter equal to that of the cylindrical portion and its inner diameter is significantly smaller than that of the bearing 34 against which it is supported, while releasing well the central portion of the door 34 which must remain free

  to receive electrical connection members which will be described later.

  When the base 31 is engaged in the segment 2, it is free to pivot and it can give it the orientation that one wants since it is completely independent of the annular ring 32. To immobilize the base 31 in its place and according to ['correct orientation, it screws the ring 32 on the thread 22 of the segment 2, which has no effect on the base 31, no element of one interpenetrant element of the other, it that is to say that the base 31 and the ring 32 can freely have a relative movement which is reflected here by

  the immobility of the base 31 and the rotation of the ring 32 during its screwing.

  In FIGS. 1 to 6, the base 31 is integral with plates 40 which are suitably spaced and

parallel to each other.

  The fastening of the base 31 and the plates 40 is obtained here by a material which is hot plastic and cold cure such as an electrically insulating synthetic resin 41 which fills the volume defined by the inner cylindrical wall of the barrel 33 and by the range 34 which constitutes a solid bottom, the plates 40 being held in place during the

  hardening of the resin, after which the whole forms a rigid whole.

  These plates here wind conductive electrodes of electricity, in which case they wind

  connected to a DC power source (not shown).

  In practice, regardless of the number of plates 40 (and therefore whatever the number of electrodes) this set pellet 31 - plates 40 - resin 41 is designated by the word

  electrode >> in the singular, according to a practice already used by professionals.

  Some of these conductive plates each have a frame set on at least trots

from their sides.

  Thus, with the example shown, the plates 42 are bare while the plates 43 each have a frame 44 of insulating material which is set on trots of their sides, the

  fourth rib, embedded in the resin 41 being lacking.

  The frame 44 prevents the current from passing from one electrode 42 to the other closest, without passing through the electrode 43 which is interposed, this frame 44 having the effect that the height and the width of these electrodes 43 higher than the height and width of the

electrodes 42.

  Except in the case of plates forming bipolar electrodes, which does not have to be described here, the plates 42 wind electrically connected to a pole and the plates 43 wind electrically connected to the opposite pole, in particular by means of pins 45 and 46 (FIG. 5) which are embedded in the resin 41 but which cross with contact one plate out of two and pass

  freely, without contact, in notches aligned with the other plates.

  The pins 45 and 46 wind electrically connected to connection terminals respectively 47 and 48 which appear externally in the central part of the door 34, and remain free of access thanks to the annular shape of the fastening organ, namely here

  the ring 32, which determines a central vice 38.

  With this structure, it is easy to connect and disconnect lugs of known type 51 and 52 carry the denuded end of supply wires 53 and 54 since the connection terminals 47 and 48 are still accessible, regardless of whether the ring 32

  either in place or not (Figures 5 and 6).

  In addition, the base 31 (in the door 34 and the terminals 47 - 48 are part) and the ring 32 being independent of one another, it is possible to orient the base 31 according to the desired location for them. outside terminals 47 and 48, and immobilize it in any queue

  orientation, by screwing the ring 32 on the thread 22 of the segment 2.

  The plates 40 wind made integral with the base 33 and the electrical connection members by the resin 41 but it is good to strengthen this attachment and, for this purpose, the plates 40 wind held together but electrically isolated from each other by insulating supports who encircle them and who each have two opposite racks

  receiving two opposite edges of each plate 40.

  Here, the assembly has three identical supports 60 to each other, which is why

describes only one.

  Each support 60 is formed of two parts substantially respectively horseshoe 61 upper and lower 62, reunées by fasteners 63 of any known type, located laterally and about halfway up. Each support 60 surrounds

  thus the entire group of plates 40 surrounding it.

  The two parts 61 and 62 each carry a rack respectively 64 and 65 and these two racks 64 and 65 face each other so that two opposite sides of each plate 40 can be engaged in two slots located opposite one another and belonging to both

racks (Figure 4).

  Thus, the plates 40 are effectively maintained parallel to each other, according to a spacing exactly respected and established by the calculation of the electrical characteristics of the set. As indicated above, the closure member 30 is differently constituted according to

the goal is searching.

  FIGS. 5 and 6 illustrate the case where the closure member 30 constitutes a part of the electrode, which must be supplied with electric current to perform in the water which

  circulates in the installation an electrolysis operation of any known type.

  It is then necessary to ensure the tightness between the inside of the piping segment 2 and the outside, in particular in the immediate vicinity, where the pods 51 and 52 are

  exposed ends of the power supply wires 53 and 54.

  Accordingly, it is prudent to interpose a seal 49 between the free end of the segment 2 and the door 34, this being compressed when the ring 32 is completely

  screwed on the thread 22 (Figure 5).

  The orientation of the electrode is important because, as shown in FIG. 4, the planes of the plates 40, all parallel to one another, must also be parallel to the median axial plane of the pipe segment 1, since the circulating water in the direction of the fleches F. he

  It must flow freely by meeting the least possible gene.

  It is obviously not necessary that the plates 40 extend across the flow, but even

  Slightly inclined position would be unfavorable to the proper functioning of the installation.

  This is why the freedom to orient the base 31 and thus the plates 40 that it carries is not

  frustrated by the fixing means of the base 31 put in place.

  In order for the user to be sure of the orientation that he gives to the electrode engaged in segment 2, terminals 47 and 48 may be arranged in a coordinated manner so that the user

has an external mark.

  The requirements of the drawing have made it possible to represent the terminals 47 and 48 one above the other in FIGS. 1, 2, 5, 6, 9 and 10, which has the consequence of the arrangement of FIGS. that is to say that these terminals 47 and 48 wind aligned vertically but it isjustement of an unfavorable position because drops (including condensation) may form on the terminal 47 and they may fall on the terminal 48 and cause a short circuit. It is therefore rather recommended to shift the terminals 47 and 48 to avoid that they do not

be one above the other.

  To facilitate the relative orientation of the segment 2 and the base 31, it is possible to use a cutter which prevents the positioning and / or screwing of the ring 32 if

is not correct

  According to a feature of the invention, the door 34 and the end of the pipe segment 2 comprise complementary elements to cooperate to allow the application of the door 34 against said end of the pipe segment 2 when the electrode is properly oriented, and to thwart this application when the electrode

  is misaligned, these elements being out of contact with the fastener 32.

  FIG. 1 shows an example of such a detractor: it has been cylindrical 33 and the door 34 has a radial lug 39 made in one piece with these elements, and the end of the pipe segment 2 has a notch 23 of shapes and dimensions similar to those of the lug 39, so that it can freely enter the latch 23 without opposing the slightest gene eng (the commitment of the base 31 until the periphery of the

  range 34 applies flat on the end of segment 2.

  This means that the lug 39 is exactly opposite the latch 23 and the relative position of these two members is obviously determined so that the plates 40 are properly oriented as in FIG. 4, when ltergot 39 penetrates fully into

ltencoche 23.

  If, on the other hand, the pin 39 and the notch 23 do not face exactly opposite each other, the pin 39 abuts at any point on the end of the segment 2 and prevents the socket 31 from penetrating into segment 2, which is the goal sought since the lack of alignment

  The pin 39 and ltencoche 23 means that the plates 40 do not wind well aligned.

  The user must then rotate the base 31 until ltergot 39 is placed in front of

  notch 23 and penetrates therein, a sign that the plates 40 are then well oriented.

  This structure imposes a single correct position for the electrode when in fact there are two since if the plates 40 must actually be in planes parallel to the median plane of the segment 1, nothing stops that one of the longitudinal edges plates 40 is located at the top rather than in the teas, that is to say that the electrode can indifferently occupy two exactly opposite positions, in

  which plates always have the same orientation.

  It is then possible to provide two lugs 39 and two notches 23 diametrically opposed, the electrode being able to be arranged in a given position or in that which corresponds to it

at 180 angle.

  As is well known to those skilled in the art, the plates 40 wear out as a function of the operating time and they must be removed periodically to replace them with

new plates.

  Concretely, this amounts to changing the assembly called "electrode", namely not only the plates 40 and their supports 60, but also the base 31 and the resin cure

  41 it contains, as well as the terminals 47 and 48 integral with the door 34 to said base 31.

  For this, we disconnect the lugs 51 and 52 after removing the power supply,

  the ring 52 is removed and the electrode is removed.

  Then, put in place a new electrode, we screw the ring 32 and reconnect the

  lugs 51 and 52, then restores the power supply.

  It is clear that after removing the used electrode and before putting the new one back in place, water will flow and the amount of water that has been lost should be minimized, so that

  have a new electrode before removing the old one.

  According to the invention (FIGS. 7 and 8), a single pellet 31 is used which does not bear any plates 40

  and therefore is not provided either with terminals 47 and 48.

  This base 31 is held in place by the ring 32 screwed on the thread 22 and ensures the tight closure of the open end of the segment 22, which is why the seal 49

must be present in a good place.

  It is then possible to leave the plant on standby, without loss of water, for as long as it is necessary to obtain a new electrode, or to perform a

  any work on the installation.

  FIGS. 9 and 1 O show another variant of the invention according to which

  uses a dummy electrode, for the sole purpose of performing demonstrations.

  Stores that sell appliances and pool products need to have a minimum of stock in order to serve their customers immediately. But these applications often require a demonstration on site, especially to verify and / or show that the electrode is well adapted to a pre-existing installation. However, a complete electrode is expensive and it is advantageous to have electrodes having all the mechanical, morphological and dimensional characteristics of a normal electrode,

but at a reduced price.

  The most expensive part of an electrode winds the plates 40 which must be in a very elaborate material and quite rare, to meet the conditions of use they must undergo. An electrode referred to as "dummy" therefore has all the external characteristics of a normal electrode but the plates 40 wind in a more ordinary material which can not give the same results as that used for plates 40 intended to actually function.

  In FIGS. 9 and 10, there are thus the same elements as in FIGS. 1 to 6.

  As this electrode can not function properly, it must be prevented that it can be confused with a normal electrode, whereas formerly nothing

distinguishes one from the other.

  A feature of the invention is that the central portion of the door 34 is pierced with a leakage-sealing hole between the interior of the pipe segment 2 and

the outside of the device.

  In Figures 9 and 10, there is a hole 70 which crosses the door 34 from one side, which eliminates any tightness since the water that is present in the pipe segment 2

  This passage can be used freely to pass outside.

  This hole 70 is clearly visible from the outside and allows the user to identify this electrode as being factitious and therefore unsuitable for its use. Wile is generally available to resellers and installers to enable them to verify and

  "physical" demonstrations and not for its functional installation.

  If inadvertently such an electrode was still installed, we would immediately see

  water out through the hole 70, revealing the impossibility of using the electrode.

  After the user has made sure that an electrode of this type could be set up, fixed and electrically connected because of its size and more generally of its shape characteristics, the electrode is dismounted for an operation. control

  later and a truly functional electrode can be installed.

  For this, it was only necessary to have a cheap factitious electrode,

  without having to keep a real electrode of high price.

  It follows from the description above that the device of the invention can be applied to

  different solutions: real electrode, dummy electrode or simple temporary shutter.
