Abstract

The cleanser is for removal of solid matter such as rags or plastic bags from a flowing fluid. It comprises a downwardly inclined, U-shaped cross-section groove (1) in which a feed screw is rotatably located (7). In its inclined section, the groove is broken through by apertures which form a grid (2), and in its opposite part the groove has an outlet aperture (9) in which the captured and upwardly transported articles (15) can leave the groove and drop into a container (10). The feed screw is freely located at its lower end, and at its upper end is motor-driven (8). The group is pivotably located around its centre point and can be swung upwards to a horizontal service position.

Description

457637 10 15 20 25 30 35 verksamt läge under det att Fig. 2 utgör en liknande vy av anordningen enligt fig. uppsvängt läge. 1 i overksamt, Den nya anordningen innefattar en i tvärsnitt U-forma d ränna med den gene- rella beteckningen l. 457637 10 15 20 25 30 35 operating position while Fig. 2 constitutes a similar view of the device according to fig. 1 in idle. The new device comprises a U-shaped gutter in cross section with the general designation 1.

Denna ränna är i en del av sin sträckning utformad som ett galler 2 med samma tvärsektion som rännan i övrigt. I praktiken kan detta utföras så att den plåt, varav rännan är framstäl ld, genombryts av ett antal utstansningar, vilka öppningar lämpligen överbryggas av gal- lerstänger.This gutter is in part of its section designed as a grid 2 with the same cross section as the gutter in general. In practice, this can be done so that the plate from which the gutter is made is pierced by a number of punches, which openings are suitably bridged by grid bars.

Ungefär vid sin mittpunkt är rännan 1 svängbart lagrad kring en axel 3, fäst eller lagrad vid uppstående organ 4 från golv- eller markplanet 5.Approximately at its center point, the gutter 1 is pivotally mounted around a shaft 3, attached or mounted to upright members 4 from the floor or ground plane 5.

Rännan är anordnad så att den i verksamt läge har sin ena ände nedsänkt i en avloppskanal 6 eller liknande, varvid rännans l nedre ände lämpligen stöder mot kanalens 6 botten.The gutter is arranged so that in the operative position it has one end immersed in a drainage channel 6 or the like, the lower end of the gutter 1 suitably supporting the bottom of the channel 6.

I rännan l är roterbart lagrad en matanskruv 7, vilken-har huvudsakligen samma ytterradie som den U-formade rännans livdel o ch vilken endast är I lagrad i sin i fig. högra ände.A feed screw 7 is rotatably mounted in the groove 1, which has substantially the same outer radius as the web part of the U-shaped groove and which is only mounted in its right-hand end in Figs.

För matarskruvens drivning är anordnad en motor 8 och rännan uppvisar i närheten av sin i fig. högra ände ett utlopp 9.A motor 8 is arranged for driving the feed screw, and the gutter has an outlet 9 in the vicinity of its right-hand end in Figs.

Med 10 betecknas i fig. en container, avsedd att upptaga de av anordningen avskilda och upptransporterade föremålen.By 10 is indicated in Fig. A container, intended to receive the objects separated and transported by the device.

Den U-formade rännan kan i sin icke genombrutna del uppvisa ett lock 11 och kanalen 6 kan vara överbryggad av ett golv 12.The U-shaped gutter can in its unbroken part have a lid 11 and the channel 6 can be bridged by a floor 12.

För att minska slitaget på rännan i dess i fig. högra del är en slityta 13 av lämpligt plastmaterial anordnaddmellan rännan och matarskruven;' En s.k. dropplåt 14 är lämpligen anordnad under den som galler utformade delen av rännan för vätskeavrinning.In order to reduce the wear on the gutter in its right-hand part in Fig. 1, a wear surface 13 of suitable plastic material is arranged between the gutter and the feed screw; A s.k. drip plate 14 is suitably arranged below the part of the gutter for liquid drainage formed as a grid.

Den nu beskrivna anordningen fungerar på följande sätt: Det med fasta föremål 15 förorenade vattnet strömmar genom kanalen 6 i den med pil angivna riktningen. Vattnet inkommer därvid i den uppåt öppna U-formade rännans 1 som galler utformade del och de f asta föremålen upp- fångas av gallret resp. matarskruven och vidarebeﬁördras av den i rotation försatta matarskruven upp till utloppet 9, där föremålen ifråga lämnar rännan och nedfaller i containern 10. Den med föremålen uppmatade vätskan avrinner till största delen via dropplâten 14. 10 457637 Det inses att den nu beskrivna anordningen ger en helt kontinuerlig nens- ning och att effekten blir stor eftersom rännan lämpligen är så dimensio- nerad, att den huvudsakligen täcker kanalens 6~bnedd. Det ar givetvis möj- ligt att använda anordningen även vid bredare kanaler genom anordnandet av styrplåtar som för in avloppsvattnet i rännan på ovan beskrivet sätt» Det inses även att anordningen ej kräver särskilt stor takhöjd.The device now described works as follows: The water contaminated with solid objects 15 flows through the channel 6 in the direction indicated by the arrow. The water then enters the upwardly open U-shaped gutter 1 as a grid-shaped part and the fixed objects are caught by the grid resp. the feed screw and is carried by the rotating auger up to the outlet 9, where the objects in question leave the gutter and fall into the container 10. The liquid fed with the objects drains for the most part via the drip plate 14. It will be appreciated that the device now described provides a complete continuous nensing and that the effect is large because the gutter is suitably dimensioned that it mainly covers the width of the channel 6 ~. It is of course possible to use the device also with wider channels by arranging guide plates which introduce the waste water into the gutter in the manner described above. It is also understood that the device does not require a particularly high ceiling height.

Rännan 1 är lämpligen så balanserad, att den med ringa kraft kan svängas upp från det i fig. 1 visade verksamma läget till det overksamma service- läge som visas i fig. 2. Ej visade organ är givetvis anordnade för att fixera rännan i dess olika lägen. Med rännan i horisontellt läge enligt fig. 2 blir hela anordningen lätt åtkomlig för service.The chute 1 is suitably so balanced that it can be swung up with little force from the operative position shown in Fig. 1 to the inactive service position shown in Fig. 2. Means not shown are of course arranged to fix the chute in its various positions. modes. With the gutter in horizontal position according to Fig. 2, the whole device becomes easily accessible for service.
