Spuitkop voor het inwendig reinigen van buizen.Nozzle for internal cleaning of pipes.
De uitvinding betreft een spuitkop welke met water onder zeer hoge druk buizen kan reinigen.The invention relates to a spray head which can clean tubes with water under very high pressure.
De spuitkop heeft hiervoor een draaiend element dat van een aantal sproeiers voorzien is en 5 tevens een aantal vaste sproeiers welke gericht zijn op de buiswand.For this purpose, the spray head has a rotating element which is provided with a number of nozzles and also a number of fixed nozzles which are directed at the tube wall.
Sproeiers van dit type zijn bekend uit de publicatie NL 1019136. Deze sproeiers zijn in de praktijk kwetsbaar gebleken en hadden een korte levensduur welke veroorzaakt wordt door de extreem hoge drukken welke noodzakelijk zijn om buizen welke in de petrochemie gebruikt 10 worden schoon te maken.Sprayers of this type are known from the publication NL 1019136. These sprayers have proved to be fragile in practice and had a short service life caused by the extremely high pressures necessary to clean tubes used in the petrochemical industry.
De onderhavige spuitkop heeft vaste sproeiers en een draaiend element dat voorzien is van sproeiers welke in verschillende richting werken. Het draaiend element is zelfafdichtend en wordt tijdens bedrijf gekoeld. Gebleken is dat het draaiend element met voldoende lengte 15 weinig drukverlies geeft en vrijwel wrijvingsloos draait. Waarbij voor de bewerking van de oppervlakken niet meer dan normale machine toleranties vereist zijn. Er is geen speciale labyrint afdichting nodig gebleken.The present spray head has fixed nozzles and a rotating element which is provided with nozzles which work in different directions. The rotating element is self-sealing and is cooled during operation. It has been found that the rotating element of sufficient length gives little pressure loss and rotates virtually without friction. Where no more than normal machine tolerances are required for surface machining. No special labyrinth seal has been found necessary.
De spuitkop heeft naar voren gericht bij voorkeur 2 sproeiers onder een hoek van ongeveer 30 20 graden om de aanslag in repen te snijden. Achter het vaste voorstuk bevindt zich het draaiende element met schuin naar voren gerichte sproeiers en bij voorkeur 2 sproeiers welke met hun hartlijn excentrisch gericht zijn en het draaiend element aandrijven. Het draaiend element dient voor het reinigen van de buis. Achteraan de spuitkop zijn bij voorkeur 2 sproeiers welke de gefragmenteerde aanslag verwijderen.The spray head preferably has 2 nozzles facing forward at an angle of about 30 degrees to cut the stop into strips. Behind the fixed front part is the rotating element with obliquely forward-facing nozzles and preferably 2 nozzles which are eccentrically oriented with their center line and drive the rotating element. The rotating element serves to clean the pipe. At the rear of the spray head are preferably 2 nozzles which remove the fragmented stop.

Met (1) is de spuitkop aangegeven. Het lichaam (2) is voorzien van een cilindrisch deel (3), voorzien van boring (4) en aansluiting (5) voor (niet getekende) toevoerbuis. Met pijl (6) is de voorkant aangeduid en met pijl (7) de achterkant. Om cilindrisch deel (3) past glijdend draaiend element (8). Met schroefdraad is kop (9) bevestigd aan cilindrisch deel (3). In het midden van 35 draaiend element (8) is kamer (10) welke met openingen (11) verbonden is met boring (4) om de in het draaiend element (8) gemonteerde sproeiers (12,13) te voeden met water onder hoge druk. Bij voorkeur 2 sproeiers (12) welke excentrisch tussen 1 en 15 millimeter ten opzichte van de hartlijn van spuitkop (1) zijn geplaatst drijven het draaiend element (8) aan. 1 of meerdere sproeiers (13) zijn schuin naar voren (6) onder een hoek (18) tussen 30 en 50 graden ten 40 opzichte van de hartlijn van spuitkop (1) gericht.The nozzle is indicated by (1). The body (2) is provided with a cylindrical part (3), provided with bore (4) and connection (5) for supply pipe (not shown). Arrow (6) indicates the front and arrow (7) the back. Sliding rotating element (8) fits around cylindrical part (3). Threaded head (9) is attached to cylindrical part (3). In the center of rotating element (8) is chamber (10) which is connected with openings (11) to bore (4) to feed the nozzles (12,13) mounted in the rotating element (8) with high-pressure water busy. Preferably 2 nozzles (12) which are eccentrically positioned between 1 and 15 millimeters with respect to the axis of the nozzle (1) drive the rotating element (8). 1 or more nozzles (13) are directed obliquely forward (6) at an angle (18) between 30 and 50 degrees to the axis of the nozzle (1).

In kop (9) zijn onder een hoek (14) tussen 25 en 35 graden ten opzichte van de hartlijn van spuitkop (1) 1 of meerdere sproeiers (15) aangebracht. Via boring (17) worden deze sproeiers gevoed. In het achtereind van spuitkop (1) zijn 1 of meerdere sproeiers (16) onder een hoek (17) tussen 30 en 50 graden ten opzichte van de hartlijn van spuitkop (1).1 or more nozzles (15) are arranged in the head (9) at an angle (14) between 25 and 35 degrees with respect to the center line of the spray head (1). These nozzles are fed via bore (17). In the rear end of the nozzle (1), one or more nozzles (16) are at an angle (17) between 30 and 50 degrees with respect to the axis of the nozzle (1).
5 Gebleken is dat deze spuitkop een lange levensduur heeft doordat het draaiend element (8) op een waterfilm draait en door het wegstromende water gekoeld wordt. Door de lage wrijving draait het draaiend element (8) zeer snel wat de reiniging bijzonder effectief maakt.It has been found that this spray head has a long service life because the rotating element (8) rotates on a water film and is cooled by the water flowing out. Due to the low friction, the rotating element (8) turns very quickly, which makes cleaning particularly effective.
De statische afdichtingen van sproeiers (12,13,15 en 16) en kop (9) zijn niet verder benoemd.The static seals of nozzles (12, 13, 15 and 16) and head (9) are not further specified.
