146903146903
Opfindelsen angår en filterindretning til rensning af væsker, især til rensning af vand til svømmebassiner, og med en beholder, i hvilken en skillevæg, der i nærheden af bunden er forsynet med en gennemløbsspalte, er således anbragt, at der dannes et indløbskammer for 5 den væske, der skal filtreres, og et filterkammer, i hvilket der findes lodret anbragte filterelementer, medens beholderbunden fra indløbskammeret hælder nedefter i retning mod filterkammeret og på sit laveste sted har en aflukkelig udtagningsåbning, ligesom filterelementerne foroven hver især er forsynet med en i filterets indre rum 10 udmundende udsugningsstuds.The invention relates to a filter device for the purification of liquids, in particular for the purification of water for swimming pools, and with a container in which a partition, which is provided near the bottom with a passage gap, is arranged so as to form an inlet chamber for the liquid. liquid to be filtered and a filter chamber in which there are vertically arranged filter elements, while the container bottom from the inlet chamber slopes downwardly towards the filter chamber and at its lowest location has a closable outlet opening, and the filter elements above each are provided with one in the interior of the filter. room 10 opening suction outlet.
Til en filterindretning af den størrelsesorden, som eksempelvis anvendes til filtrering af vand til svømmebassiner, må der stilles mange krav. På grund af de store krav der af hygiejniske grunde stilles til filterkapaciteten, såvel hvad angår renheden af det filtrerede vand 15 som gennemstrømningsmængden, må sådanne filterindretninger være simple at vedligeholde, især at rense, og simple at kontrollere med hensyn til deres funktion. Hertil hører også, at enkelte filterelementer, der er blevet funktionsudygtige, skal kunne udskiftes praktisk taget uden driftsstandsning. Når sådanne filterindretninger anvendes 20 i forbindelse med svømmebassiner, må de endvidere være således indrettet, at den eventuelle fornyelse af filterhjælpelaget kan foretages på simpel måde.For a filter device of the size used, for example, for filtering water for swimming pools, many demands must be made. Due to the high hygiene requirements for the filter capacity, both in terms of the purity of the filtered water 15 and the flow rate, such filter devices must be simple to maintain, especially clean, and simple to control for their function. In addition, some filter elements that have become inoperative must be able to be replaced virtually without shutdown. Furthermore, when such filter devices are used in connection with swimming pools, they must be arranged so that any renewal of the filter aid layer can be carried out in a simple manner.
Fra tysk patentskrift nr. 709.813 kendes en klarings- og filterindretning for væsker, der indeholder fint fordelte faste stoffer. Den 25 væske, der skal klares, føres først gennem flere efter hinanden følgende udfældningskamre og derefter gennem et tilbageskylleligt filterelement. En filterindretning af en sådan størrelsesorden, at den eksempelvis kan anvendes til filtrering af vandet i svømmebassiner, må opfylde mange forskellige krav, som ikke opfyldes af de hidtil 30 kendte filterindretninger, heller ikke hvis det tilbageskyllelige filterelement blev erstattet af i og for sig kendte pladeformede filterelementer med filterhjælpelag, der kan udfældes på disse filterelementer.German Patent No. 709,813 discloses a clearing and filtering device for liquids containing finely distributed solids. The liquid to be cleared is first passed through several successive precipitation chambers and then through a back-flush filter element. A filter device of such magnitude that it can be used, for example, for filtering the water in swimming pools, must meet many different requirements which are not met by the previously known filter devices, even if the backflush filter element was replaced by plate known per se. filter elements with filter aid layers that can be precipitated on these filter elements.
Ved opfindelsen er der blevet tilvejebragt en filterindretning af den indledningsvis nævnte art, der med en stor gennemstrømningskapaci- 2 146903 tet har en stor filtreringsevne og er simpel at vedligeholde, og hvis filterelementer påvirkes med et ensartet undertryk, ligesom skumdannelse på filterelementernes filtratudløbsside undgås.The invention provides a filter device of the kind mentioned above, which has a high filtration capacity and is easy to maintain and whose filter elements are affected with uniform underpressure, and foaming on the filtrate outlet side of the filter elements is provided.
Filterindretningen ifølge opfindelsen er ejendommelig ved, at filterele-5 menterne er med indbyrdes afstande ved siden af hinanden anbragte filterpiader med udfældelige filterhjælpelag, at udsugningsstudsene udmunder i den øverste del af et trykudligningskammer, at trykudligningskammeret ved sin nederste del er forbundet med en udsugningsledning, der fører til en sugepumpe, og at der på det dybeste 10 sted af beholderbunden er udformet en på tværs af bundhældningen forløbende rende, der udmunder i udtagningsåbningen.The filter device according to the invention is characterized in that the filter elements are spaced apart by one another, filter pads with foldable filter auxiliary layers, that the suction nozzles open in the upper part of a pressure equalization chamber, that the pressure equalization chamber at its lower part is connected to a suction line. leads to a suction pump and that at the deepest 10th place of the container bottom, a channel extending transversely to the bottom slope opens into the withdrawal opening.
Ved filterindretningen ifølge opfindelsen opnås, at den udskillelse af i væsken opløste gasser, der forårsages af det undertryk,, som frembringes ved udsugningen af den gennem filterlaget ind i filterpladens 15 indre rum strømmende væske, ikke har en uheldig indflydelse på filtreringsprocessen, idet der ikke kan dannes gasansamlinger inde i filterpladernes indre rum. Eventuelle gasbobler, der måtte blive dannet, suges ud af filterpladernes indre rum sammen med den udsugede væske, så at det sikres, at hele filterfladen forbliver virksom.In the filter device according to the invention it is obtained that the separation of gases dissolved in the liquid caused by the suction produced by the suction of the liquid flowing through the filter layer into the filter compartment 15 does not adversely affect the filtration process, since gas accumulations can be formed inside the inner compartments of the filter plates. Any gas bubbles that may be formed are sucked out of the inner compartments of the filter plates together with the extracted liquid to ensure that the entire filter surface remains operable.
20 Indkoblingen af trykudligningskammeret mellem sugepumpen og filterpladen har den fordel, at de gasbobler, der måtte blive udskilt af væsken som følge af trykforskellen, kan samle sig i trykudligningskammeret og på denne måde ikke bliver videretransporteret og således heller ikke kan føre til skumdannelse i indløbområdet til fx et svøm-25 mebassin. En anden fordel ved filterindretningen ifølge opfindelsen er, at samtlige udsugningsstudse og dermed de tilhørende filterplader vil være udsat for praktisk talt der samme undertryk, selv om den til pumpen førende udsugningsledning har et forholdsvis lille tværsnit, og alle filterplader fungerer således nogenlunde ensartet. Ved anbrin-30 gelsen af udsugningsledningen i den nederste del af trykudligningskammeret bliver udskillelsen af gasbobler af væsken på grund af det herskende undertryk yderligere fremmet og opnået i en sådan grad, at der praktisk talt ikke bliver tale om bobledannelse ved indløbet til et efterfølgende svømmebassin. Trods den ringe strømningshastighed i 35 området ved indløbs kammeret og i området ved filter kammeret bliver 3 146903 sedimenterede af fremmede stoffer, herunder de stoffer, der ved skylning af filterpladerne fjernes fra filterhjælpelaget, i stor udstrækning skyllet hen til den på det dybeste sted og på tværs af bundhældningen forløbende rende, så at de aflejrede faste stoffer kan 5 fjernes fra beholderen ved hjælp af mekaniske eller hydromekaniske midler.The coupling of the pressure equalization chamber between the suction pump and the filter plate has the advantage that the gas bubbles which may be separated by the liquid due to the pressure difference can collect in the pressure equalization chamber and in this way not be transported and thus cannot lead to foam formation in the inlet area to for example, a swim-25 pool. Another advantage of the filter device according to the invention is that all suction nozzles and thus the associated filter plates will be subjected to practically the same negative pressure, although the suction line leading to the pump has a relatively small cross-section, and thus all filter plates function fairly uniformly. By placing the suction line in the lower part of the pressure equalization chamber, the separation of gas bubbles from the liquid due to the prevailing negative pressure is further promoted and achieved to such an extent that there is practically no bubble formation at the inlet to a subsequent swimming pool. Despite the low flow rate in the region of the inlet chamber and in the area of the filter chamber, 3,690,903 sedimented by foreign substances, including those which, when rinsing the filter plates, are removed from the filter auxiliary layer, are largely flushed to it in the deepest place and at extending over the bottom slope so that the deposited solids can be removed from the container by mechanical or hydromechanical means.
Skillevæggen kan have flere gennemgangsåbninger, hvorved det opnås, at de strømningsturbulenser, der opstår i indløbskammeret som følge af væskens indstrømning i dette, praktisk taget ingen indvirk-10 ning har på væsken i filter kammeret, så at der under filterindretningens drift især ikke kan forekomme ødelæggelser af de påførte filter-hjælpelag. 'The partition wall may have several passage openings, whereby the flow turbulence which occurs in the inlet chamber as a result of the flow of liquid therein has practically no effect on the liquid in the filter chamber, so that during operation of the filter device, especially, destruction of the applied filter aid layers. '
Der kan ved beholderbunden være anbragt i det mindste én, i hovedsagen parallelt med renden forløbende række af dyser, hvis dysemun-15 dinger er rettet mod renden. Herved opnås en væsentlig forbedring af den ovenfor beskrevne rensningsproces, især når et brugt filtei— hjælpelag er blevet skyllet af hver sin af filterpladerne. Ved tilførsel af ekstra, fortrinsvis med stor hastighed gennem dyserne indført væske kan de ret betydelige mængder af filterhjælpelagsmateriale 20 skylles ned i udtagningsrenden, fra hvilken de så kan fjernes gennem åbningen i sidevæggen.At least one, generally parallel to the gutter, parallel to the gutter may be arranged at the container bottom, the nozzle nozzles of which are directed to the gutter. This results in a significant improvement in the cleaning process described above, especially when a used filter-aid layer has been rinsed by each of the filter plates. By supplying extra fluid, preferably at a high velocity through the nozzles, the quite substantial amounts of filter auxiliary material 20 can be flushed down the withdrawal trench, from which they can then be removed through the opening in the sidewall.
Især når filterindretningen ifølge opfindelsen anvendes i forbindelse med svømmebassiner, kan der i indløbs kammeret fordelagtigt være anbragt en varmeveksler, som er forbundet med et opvarmningssy-25 stem. Opvarmningen af vandet i svømmebassinet kan da foretages på en meget simpel måde, og varmevekslingens virkningsgrad vil som følge af den stærke turbulens i vandet i indløbskammeret og de dermed forbedrede varmeovergangsforhold blive væsentligt forbedret. En yderligere fordel opnås ved, at kedelstensdannelse i varmeveksleren 30 undgås, da varmeveksleren eksempelvis kan anvendes i forbindelse med varmeoverførende olie. De ulemper, der er forbundet med de hidtil sædvanligvis anvendte opvarmningssystemer, hvor en del af svømmebassinvandet føres gennem en varmeveksler, som står i umiddelbar forbindelse med et forbrændingskammer, undgås derved. Da 4 146903 der ved den omhandlede udførelsesform kan anvendes varmeover-føringsmedier med stor specifik varmekapacitet, er det muligt med små yderdimensioner at opnå en varmekapacitet, der er tilstrækkelig stor til opvarmning af vandet i et svømmebassin. I stedet for den ovenfor 5 beskrevne varmeoverføringsindretning kan der naturligvis i indløbskammeret anbringes varmespiralen hørende til et elektrisk varmeag-gregat, hvis man træffer de nødvendige elektriske beskyttelsesforanstaltninger.Especially when the filter device according to the invention is used in connection with swimming pools, a heat exchanger connected to a heating system may advantageously be arranged in the inlet chamber. The heating of the water in the swimming pool can then be done in a very simple way and the efficiency of the heat exchange will be significantly improved as a result of the strong turbulence in the water in the inlet chamber and the improved heat transfer conditions. A further advantage is obtained by avoiding the formation of scales in the heat exchanger 30, as the heat exchanger can be used, for example, in connection with heat transfer oil. The disadvantages associated with the hitherto commonly used heating systems, where a portion of the swimming pool water is passed through a heat exchanger which is in direct contact with a combustion chamber, is thereby avoided. Since in the present embodiment heat transfer media with large specific heat capacity can be used, it is possible with small outer dimensions to obtain a heat capacity sufficiently large to heat the water in a swimming pool. Of course, instead of the heat transfer device described above, the heating coil of an electric heater can be placed in the inlet chamber if the necessary electrical protective measures are taken.
I det følgende vil en udførelsesform for indretningen ifølge opfindel-10 sen blive nærmere beskrevet under henvisning tii den skematiske tegning, på hvilken fig. 1 skematisk viser et længdesnit i filterindretningen til et svømmebassin, fig. 2 filterindretningen set fra oven, 15 fig. 3 trykudligningskammeret set fra siden og delvis i snit, og fig. 4 et snit efter linjen IV-IV i fig. 1 i en filterplade.In the following, an embodiment of the device according to the invention will be described in more detail with reference to the schematic drawing, in which fig. 1 is a schematic longitudinal sectional view of the filter device for a swimming pool; FIG. 2 is a top view of the filter device; FIG. 3 is a side elevational and partial sectional pressure equalization chamber; and FIG. 4 is a sectional view taken along line IV-IV of FIG. 1 in a filter plate.
Den i fig. 1 viste filterindretning, der er beregnet til brug i forbindelse med et svømmebassin, har en åben, rektangulær beholder 1, der ved hjælp af en skillevæg 2 er opdelt i et indløbskammer 3 og et 20 filterkammer 4. Skillevæggen 2 er anbragt således, at der forneden dannes en gennemløbsspalte 5. Skillevæggen har endvidere i det ved sidevæggene beliggende område et antal gennemgangsåbninger 6, der strækker sig i hele skillevæggens højde. Beholderen 1's bund 7 skråner således, at den falder i retning fra indløbskammeret 3 mod filter-25 kammeret 4, og den har på det dybest beliggende sted en på tværs af bundhældningen forløbende rende 8. Denne rende har, som det fremgår af fig. 2, ved sin ene ende en forskydelig udtagningsåbning 9, medens der ved den modstående ende er anbragt en skylledyse 10, hvis munding er rettet langs renden 8 og mod udtagningsåbningen 9.The FIG. 1, which is intended for use in connection with a swimming pool, has an open rectangular container 1 which is divided by means of a partition 2 into an inlet chamber 3 and a filter chamber 4. The partition 2 is arranged so that a passageway gap 5 is formed below the partition, furthermore, in the area adjacent to the side walls, a number of passage openings 6 extend throughout the height of the partition. The bottom 7 of the container 1 slopes so that it falls in the direction from the inlet chamber 3 towards the filter chamber 4, and it has at its deepest location a trough 8 extending transversely to the bottom slope. 2, at one end is a displaceable recess opening 9, while at the opposite end a flushing nozzle 10 is provided, the mouth of which is directed along the gutter 8 and towards the recess opening 9.
30 I bundområdet er der endvidere anbragt to dyserækker 11 og 12, der forløber i hovedsagen parallelt med renden 8, og hvis dysemundinger er rettet mod renden. Dyserækkerne 11 og 12 er ligesom skylledysen 10 tilsluttet en trykvandslesning 13. Gennem ventiler 14 og 15 kan henholdsvis dyserækkerne 11 og 12 og dysen 10, når det ønskes, 35 tilføres vand.30 In the bottom region there are also arranged two nozzle rows 11 and 12 which extend substantially parallel to the gutter 8 and whose nozzle mouths are directed to the gutter. The nozzle rows 11 and 12 are connected to a pressure water reading 13. Like the rinsing nozzle 10, through valves 14 and 15, respectively, the nozzle rows 11 and 12 and the nozzle 10 can be supplied with water.
146903 5 I filterkammeret 4's bundområde er der endvidere anbragt to tværdragere 16 og 17, på hvilke filterplader 18 er anbragt på højkant. Tværdragerne er hensigtsmæssigt forsynet med afstandsholdere 19, der sikrer en nøjagtig afstand mellem de parallelt ved siden af hinanden 5 beliggende filterplader 18.In addition, in the bottom area of the filter chamber 4 are two transverse supports 16 and 17, on which filter plates 18 are placed on a high edge. The transverse supports are conveniently provided with spacers 19 which ensure an accurate distance between the filter plates 18 located parallel to one another 5.
Filterpladerne kan på kendt måde være udformet hult og består af et filterklæde og et derpå anbringeligt filterhjælpelag af diatomit, aktivkul, blandinger af disse to stoffer eller andre filterhjælpelagsmateri-aler. En særlig fordelagtig udførelsesform for filterpladerne vil nu 10 blive beskrevet i forbindelse med fig. 4.The filter plates may in a known manner be hollow and consist of a filter cloth and a filter auxiliary layer of diatomite, activated charcoal, mixtures of these two substances or other filter auxiliary layer materials. A particularly advantageous embodiment of the filter plates will now be described in connection with FIG. 4th
Filterpladerne 18 er hver især ved deres øverste ende forsynet med en udsugningsstuds 20, der udmunder i et trykudligningskammer 21. Forbindelsen mellem trykudligningskammeret og filterpladerne er fortrinsvis udformet udløseligt, fx ved hjælp af en skrueforbindelse 15 eller en flangeforbindelse 22.The filter plates 18 are each provided at their upper end with an exhaust nozzle 20 which opens into a pressure equalization chamber 21. The connection between the pressure equalization chamber and the filter plates is preferably formed releasably, for example by means of a screw connection 15 or a flange connection 22.
Trykudligningskammeret 21 er ved sin nederste ende forbundet med en sugeledning 23, der fører til en pumpe 24.The pressure equalization chamber 21 is connected at its lower end to a suction conduit 23 leading to a pump 24.
Trykudligningskammeret har, som det fremgår at den skematiske illustration i fig. 3, forneden hældende vægge, der er rettet mod 20 tilslutningen 25 for sugeledningen 23. Ved denne konstruktion opnås på trods af den centrale Udsugning af væske fra trykudligningskammeret en praktisk taget ensartet trykfordeling ved indmundingerne 26 for filterpladernes udsugningsstudse.As can be seen from the schematic illustration of FIG. 3, downwardly inclined walls, directed to the connection 25 for the suction line 23. In this construction, despite the central extraction of liquid from the pressure equalization chamber, a virtually uniform pressure distribution at the inlets 26 of the suction plate of the filter plates is obtained.
I fig. 1 og 4 (i snit) er der vist en særlig fordelagtig udførelsesform 25 for de omhandlede filterplader. Disse består af en rørramme 27, der er tæt lukket og eksempelvis ved et hjørne forsynet med en udsugningsstuds 20. Ved den viste udførelsesform er rørrammen endvidere forsynet med et tværrør 28, der ved sine ender står i forbindelse med rørrammen 27's indre rum.In FIG. 1 and 4 (in section), a particularly advantageous embodiment 25 of the present filter plates is shown. These consist of a tube frame 27 which is tightly closed and, for example, at a corner provided with a suction nozzle 20. In the illustrated embodiment, the tube frame is further provided with a cross tube 28 which at its ends communicates with the inner space of the tube frame 27.
30 Mellem rørene i rørrammen er der anbragt en fortrinsvis med lodret forløbende riller forsynet støtteflade 29. Støttefladen kan være plade- 6 146903 formet og bestå af ét stykke, men består ved en særlig udførelsesform for indretningen ifølge opfindelsen af flere fortrinsvis hule profilstænger 30, der har et i hovedsagen rhombisk tværsnit, og som ved fremstillingen af rørrammen 27 indskydes mellem de tilsvarende 5 rør således, at de kommer til at ligge tæt ved siden af hinanden.30 Between the pipes in the tube frame, a preferably supporting surface 29 is provided with vertically extending grooves. The supporting surface may be plate-shaped and consist of one piece, but consists in a particular embodiment of the device according to the invention of several preferably hollow profile bars 30 which have a substantially rhombic cross-section and which, in the manufacture of the tube frame 27, is inserted between the corresponding 5 tubes so as to be close to one another.
' Sammenspændingen sker under drift som følge af det på filterfladen virkende undertryk ved en tilsvarende deformering af rørrammen.The compression takes place during operation due to the negative pressure acting on the filter surface by a corresponding deformation of the pipe frame.
Filterpladen er, som det i snit er vist i fig. 4, omgivet af et filterklæde 31, på hvilket der under drift er påskyllet et filterhjælpelag 10 32. Dette filterhjælpelag afskylles fra tid til anden afhængigt af til smudsningsgraden af det vand, der skal renses, og erstattes af et nyt udfældet filterhjælpelag.The filter plate is, as shown in section in FIG. 4, surrounded by a filter cloth 31 on which a filter auxiliary layer 10 is rinsed during operation. This filter auxiliary layer is rinsed from time to time depending on the degree of soiling of the water to be purified and replaced by a new precipitated filter auxiliary layer.
Afskylningen af filterhjælpelaget sker ved hjælp af dyser .33, der er anbragt oven over filterpladerne, og hvis mundinger er rettet mod 15 filterfladerne. Dyserne kan da eksempelvis være fastgjort til grenrør 34, der udgår fra et hovedrør 35 og er anbragt parallelt med filterpladerne og i hovedsagen symmetrisk med mellemrummet mellem filterpladerne og oven over disse, som det i fig. 2 skematisk er antydet for de to filterplader (for de øvrige filterplader er de med dyser 20 besatte grenledninger 34 antydet med stiplede linjer).The filter auxiliary layer is rinsed off by means of nozzles .33 disposed above the filter plates and whose orifices are directed to the filter surfaces. The nozzles can then, for example, be attached to manifolds 34 starting from a main pipe 35 and arranged parallel to the filter plates and generally symmetrical to the space between the filter plates and above them, as in FIG. 2 is schematically indicated for the two filter plates (for the other filter plates, the branch lines 34 occupied by nozzles are indicated by dotted lines).
Ved den foreliggende udførelsesform er der i indløbs kammeret endvidere anbragt en fx i form af en rørslange udformet varmeveksler 36, der er tilsluttet en ikke nærmere vist opvarmningsindretning.In the present embodiment, for example, in the inlet chamber is arranged, for example, in the form of a tube hose, heat exchanger 36, which is connected to a heating device not shown.
Filterindretningen ifølge opfindelsen arbejder nu på følgende måde: 25 Den åbne beholder 1 er fyldt med vand, fx til en højde i niveau med en niveaupil 37. I en afgangsledning 38, der er forbundet med pumpen 24’s trykside, og i en fra svømmebassinet kommende tilgangsledning 39 er der anbragt en tregangsventil, henholdsvis 40 og 41, der er indbyrdes forbundet ved hjælp af en forbindelsesledning 42. De to 30 ventiler 40 og 41 indstilles nu således, at pumpen gennem ledningen 42 pumper beholderens indhold tilbage til indløbskammeret 3. Det middel, der skal danne filterhjælpelaget, suspenderes da i beholderen i passende mængde og bringes til at aflejre sig på filterpladernes filterklæde. Det ved denne ventilstilling bestemte kredsløb oprethol- 7 146903 des, indtil alle filterpladerne er blevet ensartet dækket med et filter-hjælpelag.The filter device according to the invention now operates as follows: The open container 1 is filled with water, for example to a height at the level of a level arrow 37. In a discharge line 38 which is connected to the pressure side of the pump 24 and in a supply line coming from the swimming pool 39, a three-way valve 40 and 41 respectively are connected to each other by means of a connecting line 42. The two 30 valves 40 and 41 are now adjusted so that the pump through the line 42 pumps the contents of the container back to the inlet chamber 3. The means, which forms the filter auxiliary layer, is then suspended in the container in an appropriate amount and caused to deposit on the filter cloth of the filter plates. The circuit determined at this valve position is maintained until all the filter plates have been uniformly covered with a filter auxiliary layer.
Derefter omstilles de to ventiler 40 og 41 til normal drift, så at det fra svømmebassinet kommende vand, der skal renses, kan strømme ind 5 i indiøbskammeret, medens det filtrerede vand fra pumpen 24 gennem rørledningen 38 igen pumpes tilbage i svømmebassinet.Thereafter, the two valves 40 and 41 are switched to normal operation so that the water coming from the swimming pool to be purified can flow into the inlet chamber while the filtered water from the pump 24 through the pipeline 38 is again pumped back into the swimming pool.
Da pumpen 24 suger vandet ud af trykudligningskammeret, opstår der som følge af det undertryk, der dannes ved udsugningsstudsen 20 for hver filterplade, et sådant undertryk, at der suges vand fra behol-10 deren tværs gennem filterhjælpelaget og filterklædet. Vandet strømmer mellem filterklædet og støttefladen 29 gennem passende gennemgangsåbninger 43 i rørrammen ind i rørrammens indre og kan så strømme ind i trykudligningskammeret gennem udsugningsstudsen 20. I fig. 1 er filterpladen vist uden filterklæde og uden filterhjælpelag.As the pump 24 sucks the water out of the pressure equalization chamber, as a result of the negative pressure formed at the suction nozzle 20 for each filter plate, such a pressure is obtained that water is drawn from the container 10 through the filter aid layer and the filter cloth. The water flows between the filter cloth and the support surface 29 through appropriate passage openings 43 in the tube frame into the interior of the tube frame and can then flow into the pressure equalization chamber through the suction nozzle 20. In FIG. 1, the filter plate is shown without filter cloth and without filter aid layer.
15 Da beholderen 1 som følge af sugedriften kan være åben foroven, kan tilstanden for de enkelte filterpladers filteroverflade kontrolleres. Da låget 44 endvidere kan være udformet som observationsrude, kan strømningsforholdene ved hver af udsugningsstudsenes indmunding i trykudlingningskammeret, som det fremgår af fig. 2, yderligere 20 kontrolleres, så at der foruden en kontrol af filteroverfladens tilstand samtidig kan foretages en sikker kontrol af filterhjælpelagets gennemstrømmelighed.As the container 1 may be open at the top due to the suction operation, the condition of the filter surface of the individual filter plates can be checked. Furthermore, since the lid 44 can be designed as an observation pane, the flow conditions at each of the suction nozzles can be opened in the pressure leaching chamber, as shown in FIG. 2, an additional 20 is checked so that, in addition to a check of the condition of the filter surface, a safe check of the permeability of the filter auxiliary layer can be made simultaneously.
Hvis denne kontrol viser, at filterhjælpelaget må fornyes, skylles det på filterpladernes filterklæde værende filterhjælpelag af ved hjælp af 25 skylledyserne 33. Det kan da være hensigtsmæssigt også at anbringe hele skylleindretningen lodret bevægeligt mellem filterpladerne, så at der sikres en næsten fuldstændig fjernelse af det brugte filterhjælpelag.If this check indicates that the filter aid layer must be renewed, the filter aid layer which is on the filter cloths of the filter plates is rinsed off by means of the rinse nozzles 33. It may then also be appropriate to place the entire rinsing device vertically movable between the filter plates to ensure a complete removal of it. used filter aid layers.
Ved hjælp af skylledyserne 10, 11 og 12 skylles de på bunden af 30 beholderen ansamlede partikler af faste stoffer ned i renden 8 og gennem den nu åbnede udtagningsåbning 9 ud af beholderen. Derefter påføres på den ovenfor beskrevne måde et nyt filterhjælpelag.By means of the rinsing nozzles 10, 11 and 12, the particles of solids accumulated on the bottom of the container 30 are flushed down into the gutter 8 and through the now opened opening 9 out of the container. Then, in the manner described above, a new filter aid layer is applied.
