Description
3Yennöifilter Beschreibung Die Erfindung betrifft einen Filter für die Saugleitung einer Ölbrenneranlage mit Hochdruckzerstäuber, wobei mehr Öl aus dem Tank gesaugt wird, als der Brenner verbraucht, wobei das überschüssige Öl von der Druckseite des Brenners durch eine kurze Rückleitung über ein Druckminderventil im Filtergehäuse dem, bereits gefilterten Saugstrom zur Pumpe hin wieder zugeführt wird. 3Yennöifilter Description The invention relates to a filter for the suction line of an oil burner system with high pressure atomizer, with more oil from the tank is sucked as the burner is consumed, with the excess oil from the pressure side of the burner through a short return line via a pressure reducing valve in the filter housing is fed back to the already filtered suction flow to the pump will.
Zur Entlüftung des Leitungssystems bei Neu oder Wiederinbetriebnahme z.B nach längerem Stillstand, trägt bei bekannten Filtern der Rückleitungsr.aum des Filtergehäuses eine von Hand verschliepbare horizontal geführte Entlüftungsbohrung zur freien Atmosphäre hin. Eine Entlüftung vin Hand aber ist umständlich. Meist muß hierfür der Xundendienst beansprucht werden.For venting the pipe system when starting up or starting up again e.g. after a long period of standstill, the return line takes up space with known filters the filter housing has a horizontally guided ventilation hole that can be closed by hand towards the free atmosphere. However, venting by hand is cumbersome. Most of time the customer service must be used for this.
Hiermit kommt ein Brennölfilter in Vorschlag, bei welchem dadurch eine Entlüftung jederzeit selbsttätig erfolgt, daß eine Entlüftungsöffnung vom Rückführungsraum des Filtergehäuses senkrecht nach oben geführt ist, worin im Rückstrom ankommende Luftblasen sich nach oben ausscheiden können. Die Entluftungsöffnung endet in einem Schwimmergehäuse, das einstückig ist mit dem Filtergehäuse oder mit diesem fest verbunden ist und se mit diesem eine Einheit bildet. Ein schwimmer öffnet das Schwimmergehäuse zur freien Atmosphäre hin nach Maßgabe der sich ausscheidenden jjuftmenge. Bei einer anderen Ausfürhrungsform wird der ankommende Rlickstrom durch je eine besondere Verbindung in das Schwimmergehäuse hinein und aus diesem heraus dem Saugraum des Filters zugeführt.Herewith a fuel oil filter comes in suggestion, with which thereby a venting takes place automatically at any time that a vent opening from the return space of the filter housing is guided vertically upwards, wherein incoming in the return flow Air bubbles can be excreted upwards. The vent ends in one Float housing that is integral with the filter housing or fixed with it is connected and forms a unit with it. A float opens the float housing towards the free atmosphere in accordance with the departing jjuft amount. In another embodiment, the incoming return flow is passed through one each special connection into the float housing and out of this the suction chamber of the filter supplied.
Um zu vermeiden, dap während Stillstand der Anlage Öl aus dem Schwimmergehäuse durch die Pumpe und den Filter in den Tank fließen kann, ist es zweckmäßig, in den Ölrückfürraum des Filtergehäuses vor das Schwimmergehäuse ein Rückschlagventil zu ordnen.In order to avoid dap of oil from the float housing while the system is at a standstill can flow through the pump and filter into the tank, it is expedient to flow into the A check valve closes the oil return space of the filter housing in front of the float housing put in order.
Figur 1 zeigt ein Schema des erfindungsgemäßen Filters und Figur 2 ein Ausführungsbeispiel in Perspektive.FIG. 1 shows a diagram of the filter according to the invention and FIG. 2 an embodiment in perspective.
Pumpe 1 saugt Öl aus Tank- 2 durch Saugleitung 3, Filtertasse 4, Filtermasse 5, Saugleitung 6 und drückt dies zur Diese 7. Das überschüssige Ö1 wird durch Rückleitung 8 über Druckminderventil 9 in den gefilterten Ölstrem gedrückt. Etwa mitgeführte Luft scheidet im Raum 10 nach chen aus und gelangt in Schwimmergehäuse 11, dessen Schwimmer 12, je nach zufall von Luft, Ventil 13 öffnet oder schließt.Pump 1 sucks oil from tank 2 through suction line 3, filter cup 4, filter material 5, suction line 6 and presses this to this 7. The excess oil is returned through the return line 8 pressed into the filtered oil flow via pressure reducing valve 9. About carried Air separates in the room 10 after Chen and gets into the float housing 11, its Float 12, depending on the random air, valve 13 opens or closes.
In den Rückführraum des Filtergehäuses kann zweckmäßig ein Rückschlagventil 14 geordnet sein, welches bei Stillstand der n1age selbsttätig schließt.A check valve can expediently be placed in the return space of the filter housing 14, which closes automatically when the n1age comes to a standstill.
Es kann zweckmäßig bein, in die Entlüftungsöffnung 10 eine Zwischenwand 16 zu ordnen, um sicherzustellen, dap keine Luft vom Ölstrom unmittelbar zum Druckminderventil mitgerisaen; werden kann.It can expediently be in the ventilation opening 10 an intermediate wall 16 to ensure that there is no air from the oil flow directly to the pressure reducing valve carried along; can be.
