Description

Slamskrapeinnretning. Sludge scraper device.

Den foreliggende oppfinnelse går ut på en innretning til å skrape bort og transportere opp slam fra sedimenteringsbassenger eller lignende, med én skrape, som er bestemt til å forskyves langs bassengets bunn for å løse det på denne avsatte slam, samt minst én innretning til opptransportering av det løsnede slam. The present invention relates to a device for scraping away and transporting up sludge from sedimentation basins or the like, with one scraper, which is intended to be moved along the bottom of the basin to loosen it on this deposited sludge, as well as at least one device for transporting up the loosened mud.

Ved sediménteringsbassénger har man alleredé tidligere anvendt skraper som forskyves langs bassengets bunn for å skrape bort det avsatte slam. Disse skraper har vært drevet via kjeder eller liner fra motorer stasjonært plasert ved en ende av bassenget. Man har også be-nyttet separate innretninger £V forskjellig art til å transportere slammet opp. M; In the case of sedimentation basins, scrapers have already been used in the past, which are moved along the bottom of the basin to scrape away the deposited sludge. These scrapers have been driven via chains or lines from motors stationarily placed at one end of the pool. Separate devices of various kinds have also been used to transport the sludge up. M;

Det ovenfor omtalte System som har vært anvendt hittil, lider av en del ulemper som medfører at deres praktiske bruk ikke blir så effektiv som det ville være ønskelig. Som eksempel i så måte kan nevnes at anleggsomkostningene blir meget store fordi der kreves separate enheter for hvert sedimenteringsbasseng. Dessuten blir selvsagt plassbehovet stort. Skrapeinnretningene er dessuten ubekvemme og tungvinte å håndtere og krever betydelig vedlikehold for å arbeide tilfredsstillende. The above-mentioned system that has been used up to now suffers from a number of disadvantages which mean that their practical use is not as effective as would be desirable. As an example in this regard, it can be mentioned that the construction costs will be very high because separate units are required for each sedimentation basin. In addition, the need for space will of course be large. The scraping devices are also inconvenient and cumbersome to handle and require considerable maintenance to work satisfactorily.

Hensikten med den foreliggende oppfinnelse er å rydde de omtalte ulemper av veien og skaffe en innretning av den innledningsvis nevnte art som er enkel og billig i produksjon og vedlikehold, og som virker tilfredsstillende selv under krevende driftsforhold. Dette oppnår man ved å utføre innretningen med de kjennetegn som fremgår av patentkravene. The purpose of the present invention is to clear the mentioned disadvantages out of the way and provide a device of the type mentioned at the outset which is simple and cheap in production and maintenance, and which works satisfactorily even under demanding operating conditions. This is achieved by making the device with the characteristics that appear in the patent claims.

Oppfinnelsen vil bli belyst nærmere i det følgende under hen-visning til tegningen, som perspektivisk viser en utførelsesform for slamskrapeinnretningen ifølge oppfinnelsen. The invention will be explained in more detail in the following with reference to the drawing, which shows in perspective an embodiment of the sludge scraping device according to the invention.

Den viste innretning er bestemt for samtidig skraping av bunnene i tø tilstøtende sedimenteringsbassenger 1 og 2. Til dette formål er slamskrapeinnretningen oppbygget rundt en vogn 3 som kan kjøres frem og tilbake på et spor 4 ved overkanten av en vegg 5 som skiller de to bassenger 1 og 2. Vognen har bærehjul 6 og ikke viste føringshjul til føring langs sporet 4. Driften av vognen 3 skjer med en motor 7 som er montert på den og koblet til ikke viste drivhjul eller lignende. The device shown is intended for simultaneous scraping of the bottoms in adjacent sedimentation basins 1 and 2. For this purpose, the sludge scraping device is built around a cart 3 which can be driven back and forth on a track 4 at the upper edge of a wall 5 which separates the two basins 1 and 2. The carriage has carrier wheels 6 and not shown guide wheels for guidance along the track 4. The operation of the carriage 3 takes place with a motor 7 which is mounted on it and connected to not shown drive wheels or the like.

På hver langside av vognen 3 sitter en bæreramme 8 som er festet til vognen og rager ned fra denne. Den nedre del av bærerammen 8 strekker seg nær det respektive sedimenteringsbassengs bunn 9, som skråner nedover i retning utover fra veggen 5. På den nedre del av bærerammen 8 er der festet en skrapeanordning. Denne skrapeanordning består i den viste utførelsesform av to skraper 10, anordnet i V-form med spissen liggende i nærheten av nedre kant av den skrånende bunn 9. Den øvre del av skrapene 10 er festet til bærerammen 8, og deres nedre deler er forbundet innbyrdes med et tverrstykke 11 som også tjener til å bære et støttehjul 12 bestemt til å ligge an mot bunnen 9 og holde skrapene 10 i stilling like over denne. Under bevegelsen av vognen 3 frem og tilbake langs sporet 4 vil skrapene 10 skrape løs det slam som har avsatt seg på bunnen 9. På grunn av helningen av bunnen og skråstillingen av skrapene 10 vil slammet dermed bli samlet nedenfor de nedre ender av skrapene 10. On each long side of the carriage 3 is a carrier frame 8 which is attached to the carriage and projects down from it. The lower part of the support frame 8 extends close to the bottom 9 of the respective sedimentation basin, which slopes downwards in the direction outward from the wall 5. A scraper device is attached to the lower part of the support frame 8. In the embodiment shown, this scraper consists of two scrapers 10, arranged in a V-shape with the tip lying near the lower edge of the sloping bottom 9. The upper part of the scrapers 10 is attached to the support frame 8, and their lower parts are interconnected with a cross piece 11 which also serves to carry a support wheel 12 intended to rest against the bottom 9 and hold the scrapers 10 in position just above this. During the movement of the carriage 3 back and forth along the track 4, the scrapers 10 will scrape off the mud that has settled on the bottom 9. Due to the slope of the bottom and the inclined position of the scrapers 10, the mud will thus be collected below the lower ends of the scrapers 10.

Tverrstykket 11 tjener også til å bære den nedre ende av én innretning til å transportere opp det slam som er løsgjort av skrapene 10. I den viste utførelsesform utgjøres denne transportanordning av en mammutpumpe 13 hvis innløpsåpning er plasert like ved de nedre ender av skrapene 10. De to mammutpumper 13 til oppsugning av slam fra sedimenteringsbassengene henholdsvis 1 og 2 drives av en felles kompressor 14 montert på vognen 3. Pumpene har sine utløp 15 plasert rett over hver sin slamrenne 16. Rennene 16 er anbragt ved den øvre del av veggen 5 ovenfor høyeste vann-nivå i bassengene 1 og 2 og leder det opp-pumpede slam til ikke viste innretninger til behandling av dette. The crosspiece 11 also serves to carry the lower end of one device for transporting up the sludge that has been loosened by the scrapers 10. In the embodiment shown, this transport device is constituted by a mammoth pump 13 whose inlet opening is placed close to the lower ends of the scrapers 10. The two mammoth pumps 13 for suctioning up sludge from the sedimentation basins 1 and 2 respectively are driven by a common compressor 14 mounted on the carriage 3. The pumps have their outlets 15 placed directly above each of the sludge gutters 16. The gutters 16 are placed at the upper part of the wall 5 above highest water level in pools 1 and 2 and directs the pumped-up sludge to facilities not shown for processing this.

Oppfinnelsen er selvsagt ikke begrenset til det beskrevne ut-førelseseksempel, idet det er mulig å foreta endringer og tilpasninger innen rammen av patentkravene. F.eks. behøver skrapene 10 ikke å være anordnet i V-form, idet man kan tenke seg å benytte en eneste skrape anbragt i rett vinkel til kjøreretningen for vognen 3, eller også en svingbar skrape som kan stilles i forskjellige skråretninger avhengig av kjøreretningen. The invention is of course not limited to the described embodiment, as it is possible to make changes and adaptations within the framework of the patent claims. For example the scrapers 10 do not need to be arranged in a V-shape, since it is conceivable to use a single scraper placed at right angles to the direction of travel for the carriage 3, or also a pivotable scraper that can be set in different oblique directions depending on the direction of travel.
