Description

Die Erfindung betrifft eine Vorrichtung zum Reinigen einer Heizfläche, insbesondere einer Kesselanlage, bestehend aus einer antreibbaren Klopfvorrichtung nach dem ersten Teil des Patentanspruchs 1.The invention relates to a device for cleaning a heating surface, in particular a boiler system, consisting of a drivable knocking device according to the first part of patent claim 1.

Bekannte Vorrichtungen der genannten Art (vgl. z. B. (DE-A 2 710 153 oder DE-A 3 139 439) schlagen oder rütteln mit Hilfe einer bestimmten Mechanik (Pneumatik, Hydraulik oder Rotationsbewegung) die Heizfläche, so daß ein mehr oder minder großer Reinigungseffekt erzielt wird. Nachteilig ist der verhältnismäßig hohe Aufwand und die Störanfälligkeit bei Einsatz an konventionellen Kesselanlagen und insbesondere bei Kesselanlagen, die in einem geschlossenen Behälter unter Uber- oder Unterdruck arbeiten.Known devices of the type mentioned (cf. for example (DE-A 2 710 153 or DE-A 3 139 439) hit or shake the heating surface with the aid of a certain mechanism (pneumatics, hydraulics or rotational movement), so that a more or The disadvantage is the comparatively high expenditure and the susceptibility to faults when used in conventional boiler systems and in particular in boiler systems which work in a closed container under positive or negative pressure.

Der Erfindung liegt daher die Aufgabe zugrunde, eine konstruktiv einfachere und betriebssicherere Vorrichtung der eingangs genannten Art anzugeben.The invention is therefore based on the object of specifying a structurally simpler and more reliable device of the type mentioned.

Zur Lösung dieser Aufgabe werden in Verbindung mit den Merkmalen des ersten Teils des Patentanspruchs 1 die im Kennzeichnungsteil des Patentanspruchs 1 enthaltenen Merkmale vorgeschlagen.To solve this problem, the features contained in the characterizing part of claim 1 are proposed in connection with the features of the first part of claim 1.

Für die weitere Ausgestaltung bestehen im Rahmen der Erfindung mehrere Möglichkeiten. So wird nach einer bevorzugten Ausführungsform der Stößel mit Hilfe einer Feder in seiner Ausgangslage gehalten. Ohne weiteres besteht aber auch die Möglichkeit, den Stößel mit einer weiteren Spule in seiner Ausgangslage zu halten. Arbeitet der Stößel mit dem Kern zumindest teilweise unter höheren Gastemperaturen, so empfiehlt es sich, das genannte Gehäuse als Kühlkammer auszubilden. Dies kann z. B. dadurch geschehen, daß das Gehäuse mit einem entsprechenden Kühlmedium, wie Stickstoff, beschickt wird, es könnte aber auch daran gedacht werden, das Gehäuse mit äußeren Rippen durch die Außenluft zu kühlen.There are several possibilities for the further configuration within the scope of the invention. Thus, according to a preferred embodiment, the plunger is held in its initial position with the aid of a spring. However, there is also the possibility of holding the plunger in its initial position with another coil. If the plunger works with the core at least partially under higher gas temperatures, it is advisable to design the housing mentioned as a cooling chamber. This can e.g. B. happen that the housing is charged with an appropriate cooling medium, such as nitrogen, but it could also be considered to cool the housing with outer ribs by the outside air.

Im folgenden wird die Erfindung anhand einer Ausführungsbeispiele darstellenden Zeichnung näher erläutert. Es zeigen

  • Fig. 1 eine Vorrichtung zum Reinigen einer Heizfläche, und
  • Fig. 2 eine abgewandelte Ausführungsform.
The invention is explained in more detail below with reference to a drawing which shows exemplary embodiments. Show it
  • Fig. 1 shows a device for cleaning a heating surface, and
  • Fig. 2 shows a modified embodiment.

Die in den Figuren gezeigte Vorrichtung dient zum Reinigen einer Heizfläche einer Kesselanlage. In ihrem grundsätzlichen Aufbau besteht sie aus einer antreibbaren Klopfvorrichtung.The device shown in the figures is used to clean a heating surface of a boiler system. In its basic structure, it consists of a drivable tapping device.

Im Ausführungsbeispiel ist die Heizfläche 1 in einem Raum 2 angeordnet, der unter Über- oder Unterdruck steht. Die Klopfvorrichtung ist als von einem Elektromagneten 3 antreibbarer Stößel 4 ausgebildet. Diese Klopfvorrichtung ist an einen Ansatz 5 am Raumgehäuse 6 angeflanscht, der einen Durchlaß für den Stößel 4 aufweist. Dieser Durchlaß 7 ist zugleich mit einer zentrischen Füh rung für den Stößel 4 versehen. Der Elektromagnet 3 ist mit ortsfester Spule 8 und dem Stößel 4 befestigtem Kern 9 ausgeführt. Durch Aktivieren des Elektromagneten 3 wird der Stößel 4 in Bewegung gesetzt, so daß er gegen die Heizfläche 1 schlägt bzw. diese in Schwingungen versetzt. Nach Abschalten des Stromes wird der Stößel 3 mittels einer Feder 10 in seine Ursprungslage zurückgebracht bzw. in dieser Lage gehalten. Die Funktion dieser Feder 10 kann auch von einer zweiten Spule 11 übernommen werden, die dann eine Bewegung des Stößels 4 in umgekehrter Richtung nach sich ziehen würde. Diese weitere Spule 11 ist in den Zeichnungsfiguren schematisch angedeutet.In the exemplary embodiment, the heating surface 1 is arranged in a room 2 which is under positive or negative pressure. The knocking device is designed as a plunger 4 which can be driven by an electromagnet 3. This tapping device is flanged to a shoulder 5 on the space housing 6, which has a passage for the tappet 4. This passage 7 is also provided with a central Füh tion for the plunger 4. The electromagnet 3 is designed with a fixed coil 8 and a plunger 4 attached core 9. By activating the electromagnet 3, the plunger 4 is set in motion so that it strikes against the heating surface 1 or causes it to vibrate. After the current is switched off, the plunger 3 is returned to its original position or held in this position by means of a spring 10. The function of this spring 10 can also be taken over by a second coil 11, which would then cause the plunger 4 to move in the opposite direction. This further coil 11 is indicated schematically in the drawing figures.

Bei beiden Ausführungsformen ist ein zumindest den Stößel 4 mit dem Kern 9 aufnehmendes Gehäuse 12 vorgesehen. Bei der Ausführungsform nach Fig. 1 sind auch die Spulen 8, 11 bzw. die Feder 10 in diesem Gehäuse 12 angeordnet. Bei der Ausführungsform nach Fig. 2 sind dagegen die Spulen 8, 11 außerhalb des Gehäuses 12 angeordnet. Im einzelnen nicht dargestellt ist die Ausführungsform dieses Gehäuses 12 als Kühlkammer.In both embodiments, a housing 12 which accommodates at least the tappet 4 with the core 9 is provided. In the embodiment according to FIG. 1, the coils 8, 11 and the spring 10 are also arranged in this housing 12. In contrast, in the embodiment according to FIG. 2, the coils 8, 11 are arranged outside the housing 12. The embodiment of this housing 12 as a cooling chamber is not shown in detail.
