Es ist nun bei Förderleitungen bekanntgeworden. die Steuerung des Förderns in Abhängigkeit von -dem in der Förderleitung herrschenden Druck zu regeln. Bei diesen bekannten pneumatischen Förderanlagen soll die als Drossel- bzw. Absperrorgan ausgebildete Regelvorrichtung zwischen die Druckluftleitung und das Förderrohr eingebaut und durch im Förderrohr herrschenden Arbeitsdruck gesteuert werden. ' Gegenüber diesen @-orbekannten Einrichtungen besteht das Wesentliche der-Erfindung darin, daß die Beziehungen zwischen der Preßluftleitung, die durch Abzweigungen das Auflockern des Gutes im Silo bewirkt, und dem Ventilatorstromkreis durch ein Arbeitsmittel, wie z. B. ein F-lektrol-entil, selbsttätig -eregelt werden.It has now become known in delivery lines. the control of the To regulate the delivery depending on the pressure prevailing in the delivery line. In these known pneumatic conveying systems, the should act as a throttle or shut-off device trained control device installed between the compressed air line and the delivery pipe and controlled by the working pressure prevailing in the delivery pipe. ' Opposite to these @ well-known facilities, the essence of the invention is that the relationships between the compressed air line, the loosening up by branches of the goods in the silo, and the fan circuit through a work medium, how z. B. a F-lectrol valve, automatically controlled.
Wenn bei den genannten automatisch b42i?iti-Ylußten Förderanlagen das Fördergut die huftregulierungsorgane oder die Luftm(#nge bzw. den jeweiligen Luftdruck des Gutzulaufes regelt, so handelt es sich bei der Erfindung darum, die Inbetriebsetzung der Beschickungsapparatur einer pneumatisch betriebenen Förderrinne zu verriegeln. solange nicht die hierfür notwendigen Voraussetzungen gegeben sind, also wenn nicht vorher der Antriebsmotor der Rinne angelassen ist.If with the mentioned automatic b42i? Iti-Ylußten conveyor systems the conveyed material, the hoof regulating organs or the air volume or the respective Air pressure of the Gutzulaufes regulates, so it is with the invention, the Commissioning of the feeding equipment of a pneumatically operated conveyor trough to lock. as long as the necessary prerequisites are not met, that is, if the drive motor of the chute has not been started beforehand.
Das zur Regelung der Beziehungen der Preßluftleitung und des Ventilatorstromkreises verwendete Elektroventil kann als Zylinder mit Kolben ausgebildet sein. wobei der Zylinder durch je einen Rohranschluß mit der Preßluftleitung und mit dem in dieser Leitung angeordneten selbsttätig wirkenden Regelorgan finit Menibranschaltung in Verbindung steht.That for regulating the relationships between the compressed air line and the fan circuit The solenoid valve used can be designed as a cylinder with a piston. where the Cylinder through one pipe connection each with the compressed air line and with the one in this Line arranged automatically acting control element finite Menibran circuit in Connection.
Die Zeichnung veranschaulicht eitle beispielsweise Ausführungsform der Erfindung. In Abb. i wird das selbsttätig arbeitende Preßluftventil mit Mcribranschaltung von deni darunter angeordneten Elektroventil betätigt. und zwar unter Einwirkung von Preßluft.The drawing illustrates an example embodiment the invention. In Fig. I the automatically working compressed air valve with Mcribran circuit is shown operated by the solenoid valve located below. namely under influence of compressed air.
In Abb.2 sind beide Regelorgane. also das Absperrventil für die Pre131uftleitung und das Elektroventil, zu einem Ganzen zusammeilebaut.In Fig.2 there are both regulating organs. So the shut-off valve for the air line and the solenoid valve, assembled into a whole.
In Abb. i ist für die Auflockerung des im Silo i eingelagerten Gutes, eine Preßluftleituilg 2 vorgesehen, durch deren Abzweigungen die Luft über poröse Platten in das Silo t eintritt. Das so mit Hilfe von Preßluft im Silo i aufgelockerte Gut gelangt beim Auslauf über die Entleerungsvorrichtung 3 und über die Schurre 4 in die trogartige Förderrinne 5 mit gasdurchlässigem Boden 6. wobei der vom Motor 7 angetriebene Ventilator 8 die Luft zur FlieBbarmachung des Gutes liefert. In Fig. I, a compressed air duct 2 is provided for loosening up the goods stored in the silo i, through the branches of which the air enters the silo t via porous plates. The material loosened in this way with the help of compressed air in the silo i reaches the outlet via the emptying device 3 and the chute 4 into the trough-like conveyor trough 5 with a gas-permeable bottom 6, whereby the fan 8 driven by the motor 7 supplies the air to make the material flowable.
In die Prel.iluftleittlng 2 ist ein selbsttätig wirkendes Regelorgan 9 mit Membranschaltung eingebaut. Dieses Regelungsorgan 9 ,teht rillt dem einen Ende i4 einer U-förmig gebogenen kleinen Abzweigeleitung in Verbin-(lu1lg. (legen entgegengesetztes I?nde 13 an die 1'1-elil1tttleittlltg 2 angeschlossen ist. In der \Iitte dieser U-förmig gebogenen Abzweigeleitunr 1 ;, 1,1 ist ein 1?lcktroventil angeordnet, (las im vcirlicen(len Beispiel aus einem \fa-@:@eter; @n ,nid eint-ni 7.,lüuier t i @-üt l@(,lt#@r. 12 llestent. Der Magnet io liegt in dem zum \Iotor; führenden Stromkr(#is 15.In the Prel.iluftleittlng 2 an automatically acting control element 9 with a diaphragm circuit is built. This regulating element 9 is grooved at one end i4 of a U-shaped bent small branch line in connection (lu1lg Branch line 1;, 1,1 a 1? Lcktroventil is arranged, (read in the vcirlicen (len example from a \ fa - @: @ eter; @n, nid eint-ni 7., lüuier ti @ -üt l @ (, lt # @ r. 12 llestent. The magnet is located in the current circuit leading to the \ Iotor; (#is 15.
Ist dieser Stromkreis gc>chlossen und wird der Antriebsmotor 7 (leg 5 angelassen, dann zieht der :Magnet iö den #Kolben 12 an, und die Luft fließt durch das bohr 13 in den Zylinder ii*und weiter durch (las Rohr 1.1 unter die Membran des Regel-1)rgans g, so daß jetzt die- Luft aus der Preßlufticitung in die zum Silo führenden Abzweigungen eintreten kann.If this circuit is closed and the drive motor 7 (leg 5 left on, then the: magnet iö attracts the piston 12, and the air flows through the bore 13 in the cylinder ii * and further through (read tube 1.1 under the membrane of the rule-1) rgans g, so that now the air from the Preßlufticitung into the to the silo leading branches can occur.
Wird dagegen der Ventilatorstromkreis 15 unterbrochen, dann kehrt der Magnet io in seine Ruliela@ge zurück, und der aufwärts gellende Kolben 12 versperrt den Durchgang für die Preßluft, wobei die im Rohr t.l befindliche Luft in bekannter Weise ins Freie entweicht. In diesem Falle steht die Membran des Regelorgans 9 nicht mehr unter Druck, und das Ventil schließt sich durch den auf den Ventilteller wirkenden Federdruck. Die Zufuhr der Preßluft zuni Silo ist damit unterbrochen.If, on the other hand, the fan circuit 15 is interrupted, then it returns the magnet io back into its position, and the piston 12, which is barking upwards, locks the passage for the compressed air, the air in the tube t.l in known Way into the open air. In this case, the membrane of the regulating member 9 is not more under pressure, and the valve closes due to the action acting on the valve disc Spring pressure. The supply of compressed air to the silo is thus interrupted.
In Abb. 2 wird dieses üftnen und Schließen des selbsttätig wirkenden Absperrorgans 9 mit Menibranschaltung anders durchgeführt. Der niit dem Ventilatorstromkreis in Verbindung stehende Magnet io ist in seinem mittleren "Teil als kleine Stange ausgebildet, die unmittelbar unter die Membran des Absperrorgans9 greift. Bei angezogenem Magneten io wird diese Membran angehoben und damit auch das Ventil selbst geöffnet. Wird dagegen der i1Iag11ct 10 stromlos, dann sinkt auch die kleine Stange und finit ihr die Membran des Ab- sperrorgans 9 abwärts, und durch deal auf den Ventilteller wirkenden Federc(ruck wird das Absperrorgan geschlossen. .In Fig. 2 this opening and closing of the automatically acting shut-off device 9 with Menibran circuit is carried out differently. The middle part of the magnet io, which is connected to the fan circuit, is designed as a small rod that engages directly under the membrane of the shut-off device 9. When the magnet io is attracted, this membrane is raised and the valve itself is opened de-energized, then the small rod also sinks and finitely the membrane of the shut-off element 9 downwards, and the shut-off element is closed by the spring acting on the valve disk.
