Abstract

Frembringelsen angår en sikurv (101, 201) for placering i en afløbsrende (103, 203) typisk afdækket af en eller flere afdækningsriste, hvor afløbsrenden (103, 203) i dennes længderetning er indrettet til at lede afløbsvand imod et afløb (105) ved, at dennes bund (107, 207) har en nedadgående hældning imod afløbet (105). Sikurven (101, 201) er tilpasset for placering i afløbsrenden (103), og hvor sikurven (101, 201) er udformet som en aflang enhed med perforeringer (204), der udstrækker sig i afløbsrendens længderetning, hvorved afløbsvand passerer gennem sikurven (101, 201) på vej imod bunden (107, 207) af afløbsrenden (103, 203), og hvor sikurven (101, 201) sier afløbsvandet og dermed opsamler emner, som er større end sikurvens (101, 201) perforeringerne (204). Derved undgår man, at afløbsvand først filtreres ved selve afløbsristen, i stedet sørger sikurvene i afløbsrenderne for at afløbsvandet sies over hele afløbsrendens udstrækning, og man opnår en fordeling af snavs elementer i disse kurve, i stedet for at det hele samles ved afløbsristen. Dette medfører, at rengøringen af afløbsristen ikke længere skal udføres så ofte.The provision relates to a safety basket (101, 201) for placement in a drain channel (103, 203) typically covered by one or more cover grids, the drain channel (103, 203) being longitudinally arranged to direct waste water towards a drain (105) at that its bottom (107, 207) has a downward slope towards the drain (105). The sieve basket (101, 201) is adapted for placement in the drainage channel (103), and the sieve basket (101, 201) is formed as an elongate unit with perforations (204) extending longitudinally of the drainage channel, whereby drainage water passes through the sieve basket (101 , 201) towards the bottom (107, 207) of the drain gutter (103, 203), and where the squeegee (101, 201) says the sewer water and thus collects items larger than the sieve's (101, 201) perforations (204). This avoids the fact that wastewater is first filtered at the drainage grid itself, instead the sewer curves in the drainage channels ensure that the drainage water is seen over the entire extent of the drainage channel, and a distribution of dirt elements in these baskets is obtained, rather than the whole being collected at the drainage grid. This means that the cleaning of the drain grate no longer has to be carried out as often.

Description

Kombination af en afløbsrende samt en sikurv for placering i sådan afløbsrende Omfang af frembringelsenCombination of a drainage channel and a safe basket for placement in such drainage channel Scope of production

Den foreliggende frembringelse angår en kombination af en afløbsrende samt en sikurv for placering i sådan afløbsrende.The present invention relates to a combination of a drainage channel and a safe basket for placement in such drainage channel.

Baggrund for frembringelsen I forbindelse med gulvafløb, eksempelvis i forbindelse med vådrum i produktionsområder i slagterier eller lignende, kan der være placeret aflange afløbsrender (også kaldet hygiejne render) i gulvet, der har en hældning, hvorved overskydende afløbsvand via afløbsrenderne ledes hen til et afløb. Typisk vil der således være placeret aflange afløbsrender i gulvet, der har til opgave at lede afløbsvandet til en eller flere afløb placeret strategiske steder i produktionsområdet. Vådrum med sådanne afløbsrender anvendes eksempelvis ofte i forbindelse med bryggerier og slagterier, hvor afløbsrenderne er støbt ned i EPOXY gulve, og hvor der i øvrigt er meget stor fokus på, at hygiejnen er optimal. Alternativt kan gulvene også være monterede klinkegulve.Background of the production In connection with floor drains, for example in connection with wet rooms in production areas in slaughterhouses or the like, elongated drainage channels (also called hygiene trays) may be placed in the floor, which has a slope, whereby excess drainage water via the drainage channels is led to a drain. . Typically, there will thus be elongated drainage channels in the floor, which are tasked with directing the drainage water to one or more drains located at strategic locations in the production area. For example, wet rooms with such drainage gutters are often used in connection with breweries and slaughterhouses, where the drainage gutters are cast into EPOXY floors and where there is also a great focus on hygiene being optimal. Alternatively, the floors may also be tiled floors.

Typisk er der i vådrummet anvendt vand til at rengøre, producere eller andet, og vandet vil dermed være snavset og dermed også indeholde større eller mindre snavselementer. Det kan eksempelvis være slagterester i forbindelse med et slagteri.Typically, water is used in the wet room to clean, produce or otherwise, and the water will thus be dirty and thus also contain larger or smaller dirt elements. For example, there may be butcher's remains in connection with a slaughterhouse.

For at sikre at disse snavselementer ikke skylles ud i afløbet er der placeret en rist over afløbet, der filtrerer det snavsede afløbsvand og dermed sikrer, at kun snavselementer under en givet størrelse slipper igennem afløbsristen og gennem afløbet. Et problem er, at der over tid vil samles snavs over denne rist, og det medfører, at denne rist med relativt korte mellemrum skal rengøres grundet lav kapacitet. Rengøring af risten medfører, at dette afløb ikke kan anvendes i denne periode, hvilket kan forsinke produktionen. Yderligere er det tidskrævende, at man med jævne mellemrum og relativ ofte skal rense disse afløbsriste, hvis man vil undgå at afløbet blokeres.To ensure that these dirt elements are not flushed out into the drain, a grate is placed over the drain which filters the dirty effluent and thus ensures that only dirt elements below a given size pass through the drain grate and through the drain. One problem is that dirt will accumulate over this grate over time, which means that this grate must be cleaned at relatively short intervals due to low capacity. Cleaning the grate means that this drain cannot be used during this period, which can delay production. Furthermore, it is time-consuming that you must periodically clean these drainage grates regularly if you want to avoid blocking the drain.

Fra WO 2007004793 er det kendt at placere en sikurv i en vejbrønd, hvor vejbrøndens indløb er dækket af en afdækningsrist. Vejbrønden kan siges at udgøre en afløbsskål, som er dækket af afdækningsristen, og hvor vejbrøndens afløb er dækket af sikurven.From WO 2007004793 it is known to place a safety basket in a road well where the inlet of the road well is covered by a cover grate. The road well may be said to constitute a drain bowl covered by the grating grate and in which the road well drain is covered by the rice basket.

Herved kan der i sikurven opsamles emner, som passerer gennem afdækningsristen og ned i vejbrønden, således at disse emner ikke bringes med afløbsvandet ud gennem afløbet. I den beskrevne kombination af en vejbrønd og en sikurv vil sikurven dække afløbsskålens afløb. Imidlertid vil en afløbsskål af den beskrevne type være utilstrækkelig i vådrum, hvor der forekommer store mængder afløbsvand. En sikurv, som er anbragt over afløbet, vil meget hurtigt blokeres.Hereby, items in the basket can be collected which pass through the cover grate and down into the road well, so that these items are not brought out with the effluent through the drain. In the described combination of a road well and a basket, the basket will cover the drain bowl drain. However, a drain bowl of the type described will be insufficient in wet rooms where large amounts of effluent are present. A safety basket placed above the drain will be blocked very quickly.

Fra JP 2006342589 er det kendt at placere en filterdug under en afdækningsrist i en afløbsrende. Imidlertid vil en konstruktion af denne type være uegnet i vådrum, hvor der forekommer store mængder afløbsvand. En filterdug, som er anbragt i afløbsskålen åbning, vil hindre afløbsvandets flow, og afløbsrendens filterdug vil meget hurtigt blokeres.From JP 2006342589 it is known to place a filter cloth under a cover grate in a drainage channel. However, a construction of this type would be unsuitable in wet rooms where large amounts of wastewater are present. A filter cloth placed in the drain bowl opening will obstruct the flow of the drain water and the drain cloth filter cloth will be blocked very quickly.

Der har været foreslået afløbsrender, hvor indløbet er dækket af en afdækningsrist, og hvor afløbsrendens afløb er dækket af en afløbsrist, hvor afløbsvandet filtreres. Det har dog vist sig, at denne afløbsrist blokeres meget hurtigt. Da afløbsristen er placeret i afløbsrendens afløb, er den vanskelig at rense.Drain gutters have been proposed where the inlet is covered by a cover grate and where the drain gutter is covered by a drain grate where the drain water is filtered. However, it has been found that this drainage grid is blocked very quickly. Since the drain grate is located in the drain gutter, it is difficult to clean.

Formål med frembringelsenPurpose of production

Et formål med frembringelsen er at løse ovennævnte problemstillinger, herunder at løse problemet med de gentagne rengøringer af riste placeret over afløb i relation til afløbsrender.One object of the invention is to solve the above-mentioned problems, including to solve the problem of the repeated cleaning of grates placed over drains in relation to drainage gutters.

Beskrivelse af frembringelsenDescription of the production

Det opnås ifølge den foreliggende frembringelse med en kombination af en afløbsrende samt en sikurv for placering i sådan afløbsrende, der er afdækket af en eller flere afdækningsriste, hvor afløbsrenden i dennes længderetning er indrettet til at lede afløbsvand imod et afløb idet afløbsrendens bund har en nedadgående hældning imod afløbet. Sikurven er tilpasset for placering i afløbsrenden, og sikurven er udformet som en med perforinger forsynet aflang kurv, der udstrækker sig i afløbsrendens længderetning, at sikurven har en kant, der udstrækker sig i sikurvens længderetning, at denne kant er udformet, så sikurven kan hvile imod afløbsrendens øvre kant, hvorved afløbsvand passerer sikurven på vej imod bunden af afløbsrenden, og hvorved sikur ven sier afløbsvandet og dermed opsamler emner, som er større end sikurvens perforeringer. Denne kombination er særpræget ved, at der på sikurven er håndtag.According to the present invention, it is achieved with a combination of a drain channel and a safety basket for placement in such drain channel covered by one or more cover grids, the drain channel of which is longitudinally arranged to direct drain water towards a drain, the bottom of the drain channel having a downward slope. inclination towards the drain. The sewing basket is adapted for placement in the drainage channel, and the sewing basket is designed as an elongated basket with perforations extending in the longitudinal direction of the drainage channel, that the sewing basket has an edge extending longitudinally of the sewing basket, so that the sewing basket can rest. towards the upper edge of the drainage channel, whereby the drainage water passes the squeegee on its way to the bottom of the drainage channel, and whereby the sewerage friend says the drainage water and thus collects items that are larger than the sieve's perforations. This combination is distinctive in that there are handles on the basket.

Derved undgår man at afløbsvand først filtreres ved selve afløbsristen, i stedet sørger sikurvene i afløbsrenderne for at afløbsvandet sies over hele afløbsrendens udstrækning, og man opnår en fordeling af snavselementer i disse kurve, i stedet for at det hele samles ved afløbsristen. Dette medfører, at rengøringen af afløbsristen ikke længere skal udføres så ofte. Idet der på sikurven er håndtag, kan denne let løftes op fra afløbsrenden med henblik på rengøring eller udskiftning.This avoids drainage water being filtered first at the drainage grid itself, instead the sewer curves in the drainage gutters ensure that the drainage water is seen over the entire extent of the drainage channel, and a distribution of dirt elements in these baskets is obtained, rather than the whole being collected at the drainage grid. This means that the cleaning of the drain grate no longer has to be carried out as often. With handles on the basket, it can be easily lifted from the drainage gutter for cleaning or replacement.

I en udførelsesform er sikurven opbygget af en bukket plade med perforeringer i form af runde huller. Dette er en særlig produktionsvenlig måde at lave en sikurv på, og samtidig kan man forholdsvis let bruge plader med andre hulstørrelser i tilsvarende produktionsmetoder og derved opnå forskellige sikurve. Metalplader med huller masseproduceres allerede til diverse formål, og sådanne kan således blot bukkes og anvendes som sikurve.In one embodiment, the security curve is made up of a bent plate with perforations in the form of round holes. This is a particularly production-friendly way of making a basket, and at the same time, plates with other hole sizes can be used relatively easily in similar production methods, thereby obtaining different basket sizes. Metal sheets with holes are already mass-produced for various purposes, and thus can only be bent and used as a security curve.

I en udførelsesform kan sikurvens kant hvile imod afløbsrendens øvre kant lige under afløbsrendens afdækningsrist. Derved sikres, at sikurven er let tilgængelig for rengøring og yderligere sikres, at sikurven kan have den størst mulige dybde og stadig passe ned i afløbsrenden, uden at sikurvens bund hviler på afløbsrendens bund.In one embodiment, the edge of the squeegee may rest against the upper edge of the drain gutter just below the cover gutter. This ensures that the sink basket is easily accessible for cleaning and further ensures that the sink basket can have the greatest possible depth and still fit down the drainage gutter, without the bottom of the sinker resting on the bottom of the drainage gutter.

I en udførelsesform har sikurven en længde, som ikke er større end længden af afløbsrendens afdækningsrist. Derved kan en sikurv fjernes og rengøres blot ved at fjerne en enkel afdækningsrist over sikurven. Længden af afdækningsristen kan eksempelvis være 500 mm, og i dette tilfælde kunne sikurven have en længde på 495 mm.In one embodiment, the security basket has a length no greater than the length of the drawer cover grating. Thereby, a safety basket can be removed and cleaned simply by removing a simple cover grid over the safety basket. For example, the length of the cover grate may be 500 mm, and in this case, the security basket could have a length of 495 mm.

I en udførelsesform er sikurvens ydre højde ikke større end afløbsrendens mindste dybde. Afløbsrenden har varierende dybde for at sikre hældningen imod afløbet og ved at sikre, at højde af sikurv ikke er større end mindste dybde af afløbsrende, kan sikurve med samme dimensioner placeres langs hele afløbsrenden. Der er således ikke behov for specifikke sikurve til specifikke steder på afløbsrenden.In one embodiment, the outer height of the squeegee is no greater than the minimum depth of the drain. The drainage channel has varying depths to ensure the slope against the drain and by ensuring that the height of the sieve basket is not greater than the minimum depth of the drainage channel, the sieve basket with the same dimensions can be placed along the entire drainage channel. Thus, there is no need for specific safety curves for specific locations on the drainage channel.

I en udførelsesform er håndtagene opbukkede flapper udskåret i sikurvens endeflader og opbukket. Dette sikrer, at materiale, der allerede er en del af sikurven, anvendes, der er altså ikke behov for at påføre yderligere til sikurven.In one embodiment, the handles of folded flaps are cut into the end surfaces of the basket and folded. This ensures that material that is already part of the sieve basket is used, so there is no need to apply further to the sieve basket.

I en udførelsesform er antallet af perforeringer i sikurven tilpasset det afløbsvand, den skal si. Derved er sikurven tilpasset størrelsen af de emner, denne skal si fra afløbs-vandet.In one embodiment, the number of perforations in the sieve basket is adapted to the wastewater it is to say. In this way, the sieve basket is adapted to the size of the items it must say from the drain water.

I en udførelsesform er fordelingen af perforeringer i sikurven tilpasset det afløbsvand, den skal si. Dette både for at tilpasse sikurven til størrelsen af de emner, denne skal si, men også for at tilpasse til flowet på afløbsvandet, flere huller og fordelingen af disse har indflydelse på mængden og hastigheden af afløbsvandet, der kan passere sikurven.In one embodiment, the distribution of perforations in the sieve basket is adapted to the wastewater it is to say. This is not only to adapt the sieve basket to the size of the items it has to say, but also to adapt to the flow of the waste water, several holes and their distribution influence the amount and speed of the sewer water that can pass the sieve basket.

I en udførelsesform er sikurven fremstillet af rustfri stål. Dette materiale er særligt hensigtsmæssigt i forbindelse med afløb, både i forhold til holdbarhed og hygiejne.In one embodiment, the silk basket is made of stainless steel. This material is particularly suitable for drainage, both in terms of durability and hygiene.

Frembringelsen vil herefter blive forklaret nærmere under henvisning til den medfølgende tegning, hvor fig. 1A-C viser principskitser af en sikurv ifølge frembringelsen, og fig. 2A-D viser en udførelsesform af en sikurv set fra forskellige vinkler.The production will then be explained in more detail with reference to the accompanying drawing, in which fig. Figures 1A-C show principle sketches of a sack basket according to the invention, and Figs. 2A-D illustrate an embodiment of a safe basket from different angles.

Detaljeret beskrivelse af frembringelsenDetailed description of the production

Med henblik på at forklare princippet bag frembringelsen, viser fig. 1A-D principskitser af en sikurv 101 både alene og sammen med en afløbsrende 103 og et afløb 105.In order to explain the principle behind the production, FIG. 1A-D are sketches in principle of a safe basket 101 both alone and together with a drain ring 103 and a drain 105.

Fig. 1A viser en principskitse af et tværsnit af en afløbsrende 103, hvori der er placeret en sikurv 101. Sikurven hviler øverst i afløbsrenden 103. Når afløbsvand render ned imod bunden 107 af afløbsrenden 103, sies dette gennem sikurvens perforeringer. Sikurven 101 er placeret i afløbsrenden 103, således at sikurven 101 ligger nede i afløbsrenden 103 og ikke stikker op over afløbsrenden 103. Dette sker ved, at sikurvens øvre kant hviler mod indersiden af afløbsrendens øvre kant, som illustreret ved 102, hvorved sikurven 101 kan hvile lige under en rist (ikke vist) placeret over afløbsrenden 103. Derved sikres både, at sikurven 101 er under afløbsrendens niveau og yderligere sikres også, at sikurven 101 ikke hviler på bunden 107 af afløbsrenden 103. Sikurven har en højde 104 tilpasset således, at sikurven 101 på tilsvarende vis passer til den laveste ende af afløbsrenden 103. Sikurven 101 er formet som en kurv, hvorved denne kan opsamle emner fra afløbsvandet, og denne opsamling og opbevaring, indtil rengøring af sikurv, kan ske under risten på afløbsrenden 103.FIG. 1A shows a principle sketch of a cross-section of a drainage channel 103 in which is placed a squeegee 101. The sieve basket rests at the top of the drainage channel 103. When drainage water runs down to the bottom 107 of the drainage channel 103, this is said through the perforations of the sewerage basket. The squeegee 101 is located in the drainage channel 103 so that the sieve basket 101 lies down in the drainage channel 103 and does not protrude above the drainage channel 103. This is done by the upper edge of the sieve resting against the inside of the upper edge of the drainage channel, as illustrated by 102, whereby the sealing basket 101 can resting just below a grid (not shown) positioned above the drainage channel 103. This ensures that both the basket curve 101 is below the level of the drainage channel and furthermore, it is also ensured that the basket curve 101 does not rest on the bottom 107 of the drainage channel 103. The basketry has a height 104 adapted so as to that the sink basket 101 corresponds correspondingly to the lower end of the drain gutter 103. The sink basket 101 is shaped like a basket whereby it can collect items from the drain water and this collection and storage until cleaning of the sink basket can take place under the grate of the drain gutter 103.

Fig. IB viser en principskitse af en sikurv 101 set ovenfra. Heraf fremgår det, at sikurven 101 har en perforeret overflade, og ved placering over en afløbsrende 103 danner den derved en perforeret overflade over afløbsrenden 103, hvorved afløbsvand passere igennem denne perforerede overflade, inden det rammer afløbsrendens bund 107 og ledes imod afløbet 105. Sikurven kan være opbygget af en bukket plade med perforeringer i form af huller, og størrelsen samt fordelingen af disse har indflydelse på sikurvens funktion og kan være tilpasset individuelt til sikurvens anvendelsesområde og det afløbsvand, som sikurven skal si. Typisk er der interessant at have en stor perforering (lysning), hvorved sikurven kan håndtere store mængder afløbsvand uden at blokere.FIG. 1B is a top view of a baskets 101. From this it can be seen that the sieve basket 101 has a perforated surface, and when placed over a drain channel 103, it thereby forms a perforated surface over the drain channel 103, whereby drainage water passes through this perforated surface before it hits the bottom of the drain channel 107 and is directed towards the drain 105. may be constructed of a bent plate with perforations in the form of holes, the size and distribution thereof affecting the function of the sieve basket and may be individually adapted to the area of application of the sieve basket and the wastewater to be sealed by the sieve basket. Typically, it is interesting to have a large perforation (clearing), whereby the sieve basket can handle large amounts of wastewater without blocking.

Fig. 1C viser en principskitse af et afløbsrendesystem med sikurve, hvor et afløbsrendeforløb 109 fører imod et afløb 105, og hvor en hældning i bunden af afløbsrenden 103 imod afløbet 105 sikrer, at afløbsvand ledes imod afløbet 105. Flere sikurve 101 er placeret som moduler i afløbsrenden 103, og uanset hvor langs afløbsrenden 103 afløbsvandet skal ned i afløbsrenden 103 vil afløbsvandet blive siet af en af sikurvene 101. Over afløbsrenden 103 vil der typisk yderligere være placeret afløbsriste (ikke illustreret).FIG. 1C shows a principle sketch of a drainage channel system with a sewer curve, where a drainage channel run 109 leads to a drain 105 and where a slope at the bottom of the drainage channel 103 against the drain 105 ensures that drainage water is directed towards the drain 105. Several drainage curves 101 are placed as modules in the drainage channel. 103, and no matter where along the drainage channel 103 the drainage water goes down into the drainage channel 103, the drainage water will be sieved by one of the curves 101. Above the drainage channel 103 there will typically be additional drainage grids (not illustrated).

På Fig. 2A-D vises en udførelsesform af en sikurv set fra forskellige vinkler, hvor 2A er set skråt fra oven, 2B er set fra oven, 2C er set fra siden, og 2D er et tværsnit, hvor også afløbsrenden 203 og dennes bund 207 er skitseret med stiplede linjer. Her ses sikurven 201, som er en bukket plade med perforeringer i form af runde huller 204. Sikurven har yderligere en kant 205, der er udformet med henblik på at kunne hvile på indersiden af afløbsrendens øvre kant (se figur 2D). I denne udførelsesform er der håndtag 209 i enderne af sikurven 201 i form af opbukkede flapper, eksempelvis udskåret og opbukket fra endedelen 202 af sikurven 201. Ved at anvende håndtagene kan sikurven 201 forholdsvis let løftes op med henblik på tømning og/eller rengøring. Højden eller dybden er sikurven er illustreret med 208In FIG. Figures 2A-D are an embodiment of a safe basket seen from different angles, where 2A is viewed from above, 2B is viewed from above, 2C is viewed from the side, and 2D is a cross-section, where also the drain channel 203 and its bottom 207 are outlined. with dotted lines. Here is shown the curvature 201, which is a curved plate with perforations in the form of round holes 204. The curvature further has an edge 205 which is designed to rest on the inside of the upper edge of the drainage gutter (see Figure 2D). In this embodiment, handle 209 is provided at the ends of the basket basket 201 in the form of folded flaps, for example, cut out and cut from the end portion 202 of the basket basket 201. By using the handles, the basket basket 201 can be lifted relatively easily for emptying and / or cleaning. The height or depth is the curl curve is illustrated by 208

Sikurven kan være lavet af stål, men andre materialer som plast kunne også anvendes. Flere segmenter af riste er placeret over afløbsrenden, og sikurvene har en længde, som er kortere end rist segmenterne, hvorved sikurven kan løftes op, når risten over denne er fjernet.The silk basket may be made of steel, but other materials such as plastic could also be used. Several segments of the grate are placed above the drainage gutter, and the squeegee has a length that is shorter than the grate segments, whereby the squeegee can be lifted when the grate above it is removed.

Frembringelsen er ikke begrænset til de på figurerne viste og ovenfor beskrevne udførelsesformer. Andre udførelsesformer med andre former af sikurven er tænkelige indenfor rammerne af denne frembringelse og de efterfølgende krav.The production is not limited to the embodiments shown in the figures and described above. Other embodiments with other forms of the silk curve are conceivable within the scope of this invention and the subsequent claims.
