Description
Die Erfindung bezieht sich auf eine selbstentleerende Schleudertrommel mit mindestens einem Ventil zum Ablassen von Feststoffen aus der Schleudertrommel, wobei eine hydraulische Betätigung des Ventils durch Einspeisung von Steuerwasser in eine mit der Schleudertrommel rotierende Auffangrinne mittels einer ortsfesten Zuführeinrichtung erfolgt, die mit mindestens einer Austrittsöffnung für das Steuerwasser versehen ist.The invention relates to a self-draining Centrifugal drum with at least one valve for lowering of solids from the centrifugal drum, with a hydraulic Actuation of the valve by feeding Control water into a rotating drum Collecting gutter by means of a stationary feed device takes place with at least one outlet opening for the Control water is provided.
Eine derartige Schleudertrommel ist beispielsweise bekannt aus der DE 38 26 912 C1. Bei dieser Schleudertrommel ist die Zuführeinrichtung als geschlossener Kanal bis in den radial einwärts zur Auffangrinne befindlichen Bereich geführt, der auch von einer Antriebsspindel der Schleudertrommel durchdrungen wird. Der Innendurchmesser der Auffangrinne wird daher bestimmt durch den Durchmesser der Antriebsspindel und die radiale Erstreckung der Zuführeinrichtung im Bereich der Auffangrinne, wobei zusätzlich ein ausreichender radialer Abstand zwischen der ortsfesten Zuführeinrichtung und der rotierenden Auffangrinne und der rotierenden Antriebsspindel vorgesehen werden muß. Ein geschlossener Kanal benötigt in radialer Richtung wegen seiner Wand und der erforderlichen lichten Weite relativ viel Platz, so daß ein entsprechend großer Innendurchmesser der Auffangrinne erforderlich ist. Der durch das in die Auffangrinne eingespeiste Steuerwasser erzeugbare hydraulische Druck verringert sich aber mit zunehmendem Durchmesser der Auffangrinne. Es wird daher angestrebt, den Durchmesser der Auffangrinne so klein wie möglich zu gestalten.Such a centrifugal drum is known, for example from DE 38 26 912 C1. With this centrifugal drum is the feed device as a closed channel into the area radially inward to the gutter, which is also from a drive spindle of the centrifugal drum is penetrated. The inside diameter of the gutter is therefore determined by the diameter of the Drive spindle and the radial extension of the feed device in the area of the gutter, with an additional sufficient radial distance between the stationary feed device and the rotating gutter and the rotating drive spindle must be provided. A closed one Canal needed in the radial direction because of its Wall and the required clear width relatively much Space, so that a correspondingly large inner diameter of the Gutter is required. The through that in the gutter Hydraulic water that can be fed into the system However, pressure decreases with increasing diameter the gutter. It is therefore aimed at the diameter to make the gutter as small as possible.
Es wurde auch bereits, z. B. in der DE-OS 15 32 676, vorgeschlagen, die Zuführeinrichtung als doppelwandigen kreisringförmigen Körper auszubilden, der die Antriebsspindel im Bereich der Auffangrinne konzentrisch umgibt. Bei vorgegebenen Strömungsquerschnitt für das Steuerwasser kann die radiale Erstreckung der Zuführeinrichtung dadurch verringert werden. Außerdem ermöglicht diese Bauweise die Anordnung einer Vielzahl von Austrittsöffnungen für das Steuerwasser im Bereich der Auffangrinne, wodurch eine bessere Einspeisung des Steuerwassers in die Auffangrinne erzielt wird. Derartige Zuführeinrichtungen sind jedoch konstruktiv aufwendig und bedingen immer noch einen relativ großen Durchmesser der Auffangrinne. Bei allen doppelwandigen Zuführeinrichtungen besteht außerdem die Gefahr der Querschnittsverringerung durch abgelagerte Schmutz- oder Kalkpartikel.It has also been used e.g. B. in DE-OS 15 32 676, proposed the feed device as double-walled form annular body of the drive spindle concentrically surrounds in the area of the gutter. With a given flow cross-section for the control water can the radial extent of the feed device be reduced. In addition, this design enables Arrangement of a plurality of outlet openings for the Control water in the area of the gutter, creating a better feeding of the control water into the gutter is achieved. Such feeders are, however structurally complex and still require a relative large diameter of the gutter. With all double-walled Feeders are also at risk the reduction in cross-section through deposited dirt or Lime particles.
Der Erfindung liegt die Aufgabe zugrunde, eine konstruktiv einfache und kostengünstige Zuführeinrichtung für Steuerwasser zu schaffen, die einen kleineren Innendurchmesser der Auffangrinne ermöglicht als die bekannten Zuführeinrichtungen. The invention has for its object a constructive simple and inexpensive supply device for control water to create a smaller inner diameter the gutter enables than the known feeders.
Diese Aufgabe wird dadurch gelöst, daß zwischen der Auffangrinne und der Zuführeinrichtung ein Leitblech vorgesehen ist, das sich von einem unteren Bereich unterhalb der Auffangrinne bis in einen radial einwärts zur Auffangrinne gelegenen oberen Bereich erstreckt, wobei die Austrittsöffnung für das Steuerwasser gegen den unteren Bereich des Leitbleches gerichtet ist.This object is achieved in that between the gutter and the feed device is provided with a guide plate is from a lower area below the Collecting gutter up to one radially inward to the collecting gutter located upper area, the outlet opening for the control water against the lower area of the Baffle is directed.
Das Steuerwasser strömt zum oberen Bereich des Leitbleches und das über den oberen Bereich des Leitbleches hinausschießende Steuerwasser wird in die Auffangrinne geleitet. Als radiale Erstreckung der Zuführeinrichtung im Bereich der Auffangrinne ist nur die Dicke des Leitbleches zu berücksichtigen. Gegenüber bekannten Zuführeinrichtungen entfällt eine zweite Wand und die zwischen den Wänden erforderliche lichte Weite zur Bildung eines kreisringförmigen Strömungskanals bzw. die erforderliche lichte Weite für den geschlossenen Kanal. Der erforderliche radiale Platzbedarf ist dadurch erheblich geringer als bei den bekannten Lösungen und die Herstellkosten können drastisch gesenkt werden. Außerdem besteht nur eine geringe Verschmutzungsneigung der Zuführeinrichtung.The control water flows to the upper area of the baffle and that which shoots out over the upper area of the baffle Control water is led into the gutter. As a radial extension of the feed device in the area the gutter only the thickness of the baffle is to be considered. Compared to known feeders there is no second wall and the one required between the walls clear width to form an annular Flow channel or the required clear width for the closed channel. The required radial The space requirement is considerably less than in the known ones Solutions and manufacturing costs can be drastic be lowered. In addition, there is only a slight tendency to contamination the feed device.
Bei einer vorteilhaften Ausgestaltung ist die Austrittsöffnung für das Steuerwasser im spitzen Winkel aufwärts gegen die Außenwandung des Leitbleches gerichtet. Durch diese Anordnung der Austrittsöffnung bildet sich auf dem Leitblech eine zum oberen Bereich gerichtete Steuerwasserströmung aus.In an advantageous embodiment, the outlet opening is for the control water at an acute angle upwards directed against the outer wall of the baffle. By this arrangement of the outlet opening forms on the A control water flow directed towards the upper area out.
Bei einer weiteren vorteilhaften Ausgestaltung ist das Leitblech rotationssymetrisch ausgebildet und konzentrisch zur Rotationsachse der Schleudertrommel angeordnet. Durch die rotierende Auffangrinne werden Luftwirbel erzeugt, die eine Verteilung des Steuerwassers über den gesamten Umfang des Leitbleches bewirken, wodurch eine optimale Einspeisung des Steuerwassers in die Auffangrinne erreicht wird.In a further advantageous embodiment, this is Baffle plate designed to be rotationally symmetrical and concentric arranged to the axis of rotation of the centrifugal drum. By the rotating gutter creates air vortices that a distribution of the control water over the entire scope of the baffle, which ensures optimal feeding of the control water is reached in the gutter.
Bei einer weiteren vorteilhaften Ausgestaltung besitzt der obere Bereich des Leitbleches eine radial auswärts gerichtete Ausstülpung in Richtung auf die Auffangrinne. Dadurch wird ein besonders guter Übergang der Steuerwasserströmung vom Leitblech zur Auffangrinne erreicht.In a further advantageous embodiment, the upper area of the baffle a radially outward Protuberance towards the gutter. Thereby becomes a particularly good transition of the control water flow reached from the baffle to the gutter.
Bei einer weiteren vorteilhaften Ausgestaltung ist das Leitblech als Trennwand zwischen einem Getrieberaum und einem Gestelloberteil ausgebildet. Eine zusätzliche Trennwand, die das Eindringen von Steuerwasser in den Getrieberaum verhindert, kann somit entfallen.In a further advantageous embodiment, this is Baffle as a partition between a gearbox and an upper part of the frame. An additional partition, the penetration of control water into the gearbox prevented, can thus be omitted.
Eine weitere vorteilhafte Ausgestaltung ist dadurch gekennzeichnet, daß die Zuführeinrichtung aus einem elastischem Leitungsteil und einem Mündungsstück besteht, in dem die Austrittsöffnung vorgesehen ist. Dadurch wird eine kostengünstige und leicht zu integrierende Lösung erreicht.A further advantageous embodiment is characterized in that that the feed device from an elastic Line part and a mouthpiece in which the outlet opening is provided. This makes it an inexpensive and easily integrated solution.
Die Zuführeinrichtung kann in vorteilhafter Weise durch den Getrieberaum verlaufen und mit der Austrittsöffnung eine im Leitblech vorgesehene Bohrung durchdringen. Eine besondere Verbindung zwischen Leitblech und Zuführeinrichtung kann dabei entfallen. Die Oberseite des Leitbleches bleibt frei von störenden Leitungsteilen, die eine ungünstige Luftverwirbelung hervorrufen könnten.The feed device can advantageously by the gearbox run and with the outlet opening penetrate a hole provided in the baffle. A special connection between the guide plate and the feed device can be omitted. The top of the baffle remains free of disruptive line parts, which is an unfavorable Could cause air turbulence.
