Description

Besandungsanlage Die Erfindung bezieht sich auf eine Besandungsanlage für Steinsägen. Die bekannten Anlagen dieser Art arbeiten in der Weise, daß das vom Stein in einem darunter befindlichen Sammelbehälter ablaufende Stahlsandgemisch in einen über dem Stein befindlichen Schlammabscheider gepumpt wird, der das vom Schlamm befreite Stahlsandgemisch auf die Sägeschlitze verteilt. Dabei erweist es sich als unzulänglich, daß das im untersten Teil des Sammelbehälters angeordnete Ventil nicht schnell genug geschlossen werden kann, sobald ein unvorhergesehener Stillstand der Maschine eintritt. Die Folge davon ist, daß sich die Pumpe verstopft und meistens erst nach längerer Betriebsunterbrechung wieder in Gang gesetzt werden kann.Sanding plant The invention relates to a sanding plant for stone saws. The known systems of this type work in such a way that Steel sand mixture running down from the stone in a collecting container underneath is pumped into a sludge separator located above the stone, the from Sludge-freed steel sand mixture distributed over the saw slots. In doing so, it proves proved to be inadequate that the arranged in the lowest part of the collecting container Valve cannot be closed quickly enough as soon as an unforeseen event occurs The machine comes to a standstill. The result is that the pump becomes clogged and usually only restarted after a long interruption in operation can.

Mit der Anlage nach der Erfindung werden diese Unzulänglichkeiten behoben, welche im wesentlichen darin besteht, daß das im Tiefbunker angeordnete Ventil in der Weise mit einem Bremslüftmagneten gekuppelt ist, daß es dasselbe bei Stromunterbrechung schließt.With the system according to the invention, these shortcomings are eliminated fixed, which essentially consists in the fact that the arranged in the underground bunker Valve is coupled with a brake release magnet in such a way that it does the same thing Power interruption closes.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes wiedergegeben, und zwar in einem Schnitt durch den Tiefbunker.The drawing shows an exemplary embodiment of the subject matter of the invention reproduced, in a section through the underground bunker.

Die Anlage besteht aus dem Tiefbunker 1 zur Aufnahme des Stahlsandgemisches und der danebenliegenden Pumpengrube 2. Der zweckmäßigerweise nach unten spitz zulaufende Tiefbunker 1 ist etwa im oberen Drittel mit einem Rost 6 und mit einem im unteren Teil angebrachten Doppelsieb 7 versehen sowie durch eine Ansaugleitung 8 an eine Pumpe 9 in der Grube angeschlossen. Die Ansaugleitung 8 ist durch ein Kugelventil 10 verschließbar, welches durch ein Gestänge 11 über Flur zu betätigen ist. Außerdem mündet in die Ansaugleitung 8, zweckmäßigerweise mit einer Spritzdüse 12, eine durch ein Ventil 13 verschließbare, an die Frischwasserleitung 14 angeschlossene Leitung 15. Von der durch einen Motor 16 angetriebenen Pumpe 9 führt eine Druckleitung 17 in den Schlammabscheider. Des weiteren ist die Pumpe 9 über eine Leitung 18, welche durch ein Ventil 19 verschließbar ist, mit der Frischwasser-Leitung 14 verbunden. Von der Leitung 17 zweigt über Flur eine in den Tiefbunker 1 führende Leitung 20 ab, in welche ebenso wie in die Druckleitung 17 unterhalb der Abzweigung ein Quetschventil 21 bzw. 22 eingebaut ist. Das Kugelventil 10 wird über das Gestänge 11 durch einen Bremslüftmagneten 23 in dem Sinne gesteuert, daß dieser bei ausbleibendem Strom die Kugel in Schließstellung fallen läßt. Dadurch wird verhindert, daß die Pumpe 9 bei unvorhergesehenem Stillstand der Anlage verschlammt.The system consists of the deep bunker 1 for receiving the steel sand mixture and the adjacent pump pit 2. The deep bunker 1, which is expediently tapered towards the bottom, has a grate 6 in the upper third and a double sieve 7 in the lower part, as well as a suction line 8 a pump 9 connected in the pit. The suction line 8 can be closed by a ball valve 10, which is actuated by a linkage 11 above the floor. In addition, a line 15, which can be closed by a valve 13 and connected to the fresh water line 14, opens into the suction line 8, expediently with a spray nozzle 12. From the pump 9 driven by a motor 16, a pressure line 17 leads into the sludge separator. Furthermore, the pump 9 is connected to the fresh water line 14 via a line 18 which can be closed by a valve 19. From the line 17 branches off via the corridor a line 20 leading into the underground bunker 1, in which a pinch valve 21 or 22 is installed just as in the pressure line 17 below the junction. The ball valve 10 is controlled via the linkage 11 by a brake release magnet 23 in the sense that this allows the ball to fall into the closed position when there is no current. This prevents the pump 9 from silting up in the event of an unexpected standstill of the system.
