Abstract

In order to empty a centrifugal drum (1) control water is added through supply (10), and the control water is guided through outlet (14) of mouthpiece (12) against the bottom area (9) of baffle (4). A flow of control water directed towards the upper area (6) of baffle (4) is thus formed on baffle (4). The flow of control water projected over the upper area of the baffle is guided into the collecting channel (7). The space required in the radial direction to mount the baffle (4) between the driving spindle (2) and the collecting channel (7) is very small, and the baffle (4) production costs are very low.

Description

Selbstentleerende SchleudertrommelSelf-draining centrifugal drum
Die Erfindung bezieht sich auf eine selbstentleerende Schleudertrommel mit mindestens einem Ventil zum Ablassen von Feststoffen aus der Schleudertrommel, wobei eine hy¬ draulische 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-emptying centrifugal drum with at least one valve for discharging solids from the centrifugal drum, hydraulic actuation of the valve by feeding control water into a collecting trough rotating with the centrifugal drum by means of a stationary feed device which has at least one outlet opening is provided for the control water.
Eine derartige Schleudertrommel ist beispielsweise bekannt aus der DE 38 26 912 Cl. Bei dieser Schleudertrommel ist die Zuführeinrichtung als geschlossener Kanal bis in den radial einwärts zur Auffangrinne befindlichen Bereich ge¬ führt, der auch von einer Antriebsspindel der Schleuder¬ trommel durchdrungen wird. Der Innendurchmesser der Auf¬ fangrinne wird daher bestimmt durch den Durchmesser der Antriebsspindel und die radiale Erstreckung der Zuführein- richtung im Bereich der Auffangrinne, wobei zusätzlich ein ausreichender radialer Abstand zwischen der ortsfesten Zu¬ führeinrichtung und der rotierenden Auffangrinne und der rotierenden Antriebsspindel vorgesehen werden muß. Ein ge¬ schlossener Kanal benötigt in radialer Richtung wegen sei- ner Wand und der erforderlichen lichten Weite relativ viel Platz, so daß ein entsprechend großer Innendurchmesser der Auffangrinne erforderlich ist. Der durch das in die Auf- fangrinne eingespeiste Steuerwasser erzeugbare hydrauli¬ sche Druck verringert sich aber mit zunehmendem Durchmes¬ ser der Auffangrinne. Es wird daher angestrebt, den Durch¬ messer der Auffangrinne so klein wie möglich zu gestalten.Such a centrifugal drum is known for example from DE 38 26 912 Cl. In this centrifugal drum, the feed device is guided as a closed channel into the area located radially inwards to the collecting trough, which is also penetrated by a drive spindle of the centrifugal drum. The inside diameter of the collecting trough is therefore determined by the diameter of the drive spindle and the radial extension of the feed device in the area of the collecting trough, wherein a sufficient radial distance between the stationary feeding device and the rotating collecting trough and the rotating drive spindle must also be provided . A closed channel requires a relatively large amount of space in the radial direction because of its wall and the required internal width, so that a correspondingly large inside diameter of the collecting trough is required. The one through the However, the hydraulic pressure that can be generated in the collecting trough can be reduced with increasing diameter of the collecting trough. The aim is therefore to make the diameter of the collecting trough as small as possible.
Es wurde auch bereits, z. B. in der DE-OS 15 32 676, vor¬ geschlagen, die Zuführeinrichtung als doppelwandigen kreisringförmigen Körper auszubilden, der die Antriebs¬ spindel 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 rela¬ tiv großen Durchmesser der Auffangrinne. Bei allen doppel¬ wandigen Zuführeinrichtungen besteht außerdem die Gefahr der QuerSchnittsverringerung durch abgelagerte Schmutz- oder Kalkpartikel.It has also been used e.g. For example, in DE-OS 15 32 676, it is proposed to design the feed device as a double-walled annular body which concentrically surrounds the drive spindle in the region of the collecting trough. With a given flow cross-section for the control water, the radial extent of the feed device can be reduced as a result. In addition, this design enables the arrangement of a large number of outlet openings for the control water in the region of the collecting trough, as a result of which better feeding of the control water into the collecting trough is achieved. However, such feed devices are structurally complex and still require a relatively large diameter of the collecting trough. With all double-walled feed devices there is also the risk of a reduction in cross-section due to deposited dirt or lime particles.
Der Erfindung liegt die Aufgabe zugrunde, eine konstruktiv einfache und kostengünstige Zuführeinrichtung für Steuer- wasser zu schaffen, die einen kleineren Innendurchmesser der Auffangrinne ermöglicht als die bekannten Zuführein¬ richtungen. Diese Aufgabe wird dadurch gelöst, daß zwischen der Auf¬ fangrinne und der Zuführeinrichtung ein Leitblech vorgese¬ hen ist, das sich von einem unteren Bereich unterhalb der Auffangrinne bis in einen radial einwärts zur Auffangrinne gelegenen oberen Bereich erstreckt, wobei die Austritts-The invention has for its object to provide a structurally simple and inexpensive supply device for control water, which enables a smaller inner diameter of the collecting trough than the known supply devices. This object is achieved in that a baffle is provided between the collecting trough and the feed device, which extends from a lower area below the collecting trough to an upper area lying radially inwards to the collecting trough, the outlet
Öffnung für das Steuerwasser gegen den unteren Bereich des Leitbleches gerichtet ist.Opening for the control water is directed against the lower area of the baffle.
Das Steuerwasser strömt zum oberen Bereich des Leitbleches und das über den oberen Bereich des Leitbleches hinaus¬ schießende Steuerwasser wird in die Auffangrinne geleitet. Als radiale Erstreckung der Zuführeinrichtung im Bereich der Auffangrinne ist nur die Dicke des Leitbleches zu be¬ rücksichtigen. Gegenüber bekannten Zuführeinrichtungen entfällt eine zweite Wand und die zwischen den Wänden er¬ forderliche lichte Weite zur Bildung eines kreisringförmi¬ gen Strömungskanals bzw. die erforderliche lichte Weite für den geschlossenen Kanal. Der erforderliche radiale Platzbedarf ist dadurch erheblich geringer als bei den be- kannten Lösungen und die Herstellkosten können drastisch gesenkt werden. Außerdem besteht nur eine geringe Ver¬ schmutzungsneigung der Zuführeinrichtung.The control water flows to the upper area of the guide plate and the control water which shoots beyond the upper area of the guide plate is conducted into the collecting channel. Only the thickness of the guide plate has to be taken into account as the radial extension of the feed device in the area of the collecting trough. Compared to known feed devices, there is no second wall and the clear width required between the walls to form an annular flow channel or the required clear width for the closed channel. The required radial space requirement is considerably less than with the known solutions and the manufacturing costs can be drastically reduced. In addition, there is only a slight tendency for the feed device to become dirty.
Bei einer vorteilhaften Ausgestaltung ist die Austritts- Öffnung 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 Steuerwasser¬ strömung aus.In an advantageous embodiment, the outlet opening for the control water is directed upwards at an acute angle against the outer wall of the guide plate. This arrangement of the outlet opening forms on the Baffle plate a control water flow directed to the upper area.
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 Einspei- sung des Steuerwassers in die Auffangrinne erreicht wird.In a further advantageous embodiment, the guide plate is rotationally symmetrical and is arranged concentrically to the axis of rotation of the centrifugal drum. The rotating collecting trough creates air vortices which distribute the control water over the entire circumference of the guide plate, which ensures that the control water is optimally fed into the collecting trough.
Bei einer weiteren vorteilhaften Ausgestaltung besitzt der obere Bereich des Leitbleches eine radial auswärts gerich¬ tete 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 region of the guide plate has a radially outward protuberance in the direction of the collecting trough. This ensures a particularly good transition of the control water flow 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 Trenn¬ wand, die das Eindringen von Steuerwasser in den Getriebe¬ raum verhindert, kann somit entfallen.In a further advantageous embodiment, the guide plate is designed as a partition between a gear space and an upper part of the frame. An additional partition wall, which prevents the penetration of control water into the transmission space, can thus be dispensed with.
Eine weitere vorteilhafte Ausgestaltung ist dadurch ge- kennzeichnet, daß die Zuführeinrichtung aus einem elasti¬ schem Leitungsteil und einem Mündungsstück besteht, in dem die Austrittsöffnung vorgesehen ist. Dadurch wird eine ko- stengünstige und leicht zu integrierende Lösung erreicht.A further advantageous embodiment is characterized in that the feed device consists of an elastic line part and a mouthpiece in which the outlet opening is provided. This ensures a affordable and easy to integrate solution achieved.
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 Zuführeinrich¬ tung kann dabei entfallen. Die Oberseite des Leitbleches bleibt frei von störenden Leitungsteilen, die eine ungün¬ stige Luftverwirbelung hervorrufen könnten.The feed device can advantageously run through the gear space and penetrate a bore provided in the guide plate with the outlet opening. A special connection between the guide plate and the feed device can be omitted. The top of the baffle remains free of interfering line parts which could cause unfavorable air turbulence.

Ein oberer Bereich 6 des Leitbleches 4 ist radial auswärts gestülpt und auf ei¬ ne an der Unterseite der Schleudertrommel 1 vorgesehene Auffangrinne 7 gerichtet, die über einen Kanal 8 mit einem nicht dargestellten Ventil zur Entleerung der Schleuder¬ trommel 1 verbunden ist. Unterhalb der Auffangrinne 7 ist ein unterer Bereich 9 des Leitbleches 4 vorgesehen, der mit einer Zuführeinrichtung 10 in Verbindung steht, die durch den Getrieberaum 5 verläuft. Die ZuführeinrichtungIn the drawing, 1 denotes a centrifugal drum which, driven by a drive spindle 2, rotates in an upper frame part 3, which is separated from a gear chamber 5 by a guide plate 4. An upper region 6 of the guide plate 4 is turned radially outward and directed onto a collecting trough 7 provided on the underside of the centrifugal drum 1, which is connected via a channel 8 to a valve (not shown) for emptying the centrifugal drum 1. A lower region 9 of the guide plate 4 is provided below the collecting trough 7 and is connected to a feed device 10 which runs through the gear space 5. The feeder

Dadurch bildet sich auf dem Leitblech 4 eine zum oberen Bereich 6 des Leitbleches 4 gerichtete Steuer¬ wasserströmung aus.

As a result, a control water flow directed toward the upper region 6 of the guide plate 4 is formed on the guide plate 4.
