Equipment for cleaning a heating surface (1) contained in a chamber (6), particularly of a boiler installation, consisting of a striker equipment with a propellable rammer (4) in a rammer housing (12), characterized in that the rammer drive consists of an electromagnet (3) with a stationary coil (8) and of a core (9) attached to the rammer (4) in the rammer housing (12) and that the rammer housing (12) itself is attached to a flanged shoulder (5) of the chamber (6) that possesses a rammer passage (7) constructed as a rammer guide.

Description

Die Erfindung betrifft eine Vorrichtung zum Reinigen einer Heiz­fläche, insbesondere einer Kesselanlage, bestehend aus einer an­treibbaren Klopfvorrichtung.The invention relates to a device for cleaning a heating surface, in particular a boiler system, consisting of a drivable knocking device.

Bekannte Vorrichtungen der genannten Art (vgl. z. B. DE-OS 31 39 439) 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 Über- oder Unterdruck arbeiten.Known devices of the type mentioned (see, for example, DE-OS 31 39 439) beat or shake the heating surface with the aid of a certain mechanism (pneumatics, hydraulics or rotational movement), so that a more or less large cleaning effect is achieved. Disadvantages are the relatively 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 ist die Klopfvorrichtung als von einem Elektromagneten antreibbarer Stößel ausgebildet.To achieve this object, the knocking device is designed as a plunger that can be driven by an electromagnet.

Für die weitere Ausgestaltung bestehen im Rahmen der Erfindung mehrere Möglichkeiten. So ist nach einer bevorzugten Ausführungs­form dieser Elektromagnet mit ortsfester Spule und auf dem Stößel befestigtem Kern ausgeführt. Zweckmäßigerweise wird 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. Soll dieser Stößel in einem unter Über- oder Unterdruck stehenden Raum arbeiten, so wird man zumindest den Stößel mit dem Kern in einem Gehäuse anordnen. Die Spule bzw. die Spulen können dann je nach Bedarf innen oder außen angeordnet werden. 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. According to a preferred embodiment, this electromagnet is designed with a fixed coil and a core attached to the plunger. The plunger is expediently held in its initial position with the aid of a spring. Without there is also the possibility of holding the plunger in its starting position with another coil. If this plunger is to work in a space under positive or negative pressure, then at least the plunger with the core will be arranged in a housing. The coil or coils can then be arranged inside or outside as required. 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. done by charging the housing 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 with a centric Füh tion for the plunger 4 provided. 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.
