Abstract

The connection element (20) disclosed in EP-A-0 315 961 has a cross-section that promotes a favourable flow. There is also the danger of clogging in corners along the external contour. This danger is eliminated by the cross-section of the new connection element. Said element is consistent with the flow and is therefore arrow-shaped (34), at least in the direction of the inflowing fluid. The cross-section of the new connection element resembles that of a ship.

Vorrichtung an einer von außen nach innen durchströmten SiebtrommelDevice on a through-flow from outside to inside the screening drum
Die Erfindung bezieht sich auf eine Vorrichtung zum durchströmenden Behandeln von Textilgut, Vliesen oder Papier mit einem gasförmigen oder flüssigen, in der Vorrichtung umgewälzten Behandlungsmittel mit einer unter Saugzug stehenden, stirnseitig Böden aufweisenden durchlässigen Trommel als Transportelement, welche an ihrem Umfang mit einem Siebgewebe bedeckt ist, wobei zwischen den Böden der Trommel Blechstreifen ungebogen sich von Boden zu Boden gerade erstrecken, deren Breitenausdehnung sich in radialer Richtung erstreckt, und zwischen den Blechstreifen gleichmäßig über die Länge der Trommel verteilt Verbindungselemente angeordnet sind, die dem Sollabstand der unmittelbar benachbarten Blechstreifen entsprechend breit ausgebildet und beidseitig mit den angrenzenden Blechstreifen fest verbunden sind, wobei das jeweilige Verbindungselement stegförmig ausgebildet und in Umfangsrichtung der Trommel mit mindestens einer Bohrung versehen ist, für mindestens eine Schraube und/oder ähnliches mit einem Gewinde versehenes Befestigungselement, und mit den zwei benachbarten Blechstreifen oder Verbindungselementen verbindbar ist,The invention relates to a device for the flow-through treatment of textile, nonwovens or paper with a gaseous or liquid, circulated in the device treatment agent with a standing under suction, frontal bottoms having permeable drum as a transport element, which is covered at its periphery with a mesh wherein between the bottoms of the drum sheet metal strips unbent extending straight from floor to floor, the width of which extends in the radial direction, and between the metal strips evenly distributed over the length of the drum connecting elements are arranged corresponding to the nominal distance of the immediately adjacent metal strip correspondingly wide and are firmly connected on both sides with the adjacent metal strips, wherein the respective connecting element web-shaped and provided in the circumferential direction of the drum with at least one bore, for at least one screw and / o the similar threaded fastener, and connectable to the two adjacent sheet metal strips or fasteners,
Eine Vorrichtung dieser Art ist durch die EP-A-0 315 961 bekannt. Sie hat den unübertroffenen Vorteil, dass sie höchst luftdurchlässig ist, ohne dass dadurch die Stabilität der Trommel vermindert ist. Ohne auf eine Schweißkonstruktion zurückgreifen zu müssen, sind durch die hier vorgesehene Schraubverbindung die in Umfangsrichtung verlaufenden Verbindungselemente mit den längs über die Trommel sich erstreckenden Blechstreifen rund über die Trommel fest verbunden. Die so nachteiligen Gefügeverwandlungen im Metall beim Herstellen von ansonsten notwendigen Schweißnähten sind bei dieser Schraubkonstruktion vermieden.A device of this kind is known from EP-A-0 315 961. It has the unsurpassed advantage of being highly air-permeable without reducing the stability of the drum. Without having to resort to a welded construction, are provided by the screw provided here, the circumferentially extending connecting elements with the longitudinally extending over the drum sheet metal strip around the drum. The disadvantageous structural changes in the metal during the manufacture of otherwise necessary welds are avoided in this screw construction.
Die Verbindungselemente gemäß der EP-A-0 315 961 weisen nur eine der Stabilität genügende Wandstärke auf. Deshalb sind sie stegförmig ausgebildet und im Bereich der Schrauben zur Aufnahme der Schrauben dicker als im mittleren Bereich herge- stellt. Es hat sich in der Praxis herausgestellt, dass in den Übergängen von der Wandung in Höhe der Schrauben zu dem mittleren Bereich und auch an anderen Stellen Verschmutzungen auftraten. Flusen setzten sich an den Verbindungselementen fest und hinderten den Durchströmungseffekt.The connecting elements according to EP-A-0 315 961 have only one of the stability sufficient wall thickness. Therefore, they are bar-shaped and thicker in the area of the screws for receiving the screws than in the middle area. provides. It has been found in practice that contamination occurred in the transitions from the wall at the level of the screws to the central area and also at other locations. Fluff stuck to the fasteners and prevented the flow-through effect.
Es liegt der Erfindung die Aufgabe zugrunde, eine Konstruktion zu finden, bei der eine Verschmutzung an den Verbindungselementen nicht mehr auftritt, mit Vorteil sogar der Durchströmungseffekt vergrößert wird.It is the object of the invention to find a construction in which contamination on the connecting elements no longer occurs, advantageously even the flow-through effect is increased.
Ausgehend von der Vorrichtung nach der EP-A-0 315 961 ist die Lösung der gestellten Aufgabe dadurch gefunden, dass das Verbindungselement zumindest über einen Teil seiner radialen Länge strömungsgünstig ausgebildet ist. Dies ist erreicht, wenn der radial außen liegende Bereich des Verbindungselementes pfeilförmig ausgebildet ist, sich in dieser Breite dann bis zur radial inneren Schraube erstreckt und mit Vorteil dann wieder pfeilförmig spitz zuläuft. Zwischen den Schrauben ist die Breite des Körpers nur von geringer, die Stabilität beeinflussender Bedeutung, weswegen hier der Körper aus Gewichtsgründen hohl ausgebildet sein kann.Based on the device according to EP-A-0 315 961, the solution of the stated problem is found in that the connecting element is formed aerodynamically favorable at least over part of its radial length. This is achieved when the radially outer region of the connecting element is formed arrow-shaped, then extends in this width to the radially inner screw and then advantageously tapers pointed back arrow. Between the screws, the width of the body is only small, the stability of influencing importance, which is why here the body can be made hollow for weight reasons.

Die Siebtrommelvorrichtung nach Fig. 1 entspricht der z. B. nach der EP-A-0 315 961 . Auf die Offenbarung in dieser Schrift wird Bezug genom men.The Siebtrommelvorrichtung of FIG. 1 corresponds to the z. B. according to EP-A-0 315 961. Reference is made to the disclosure in this document.
Eine Siebtrommelvorrichtung besteht grundsätzlich aus einem etwa rechteckigen Gehäuse 1 , das durch eine Zwischenwand 2 in einen Behandlungsraum 3 und einen Ventilatorraum 4 unterteilt ist. Im Behandlungsraum 3 ist die Siebtrommel 5 und konzen- trisch zu dieser im Ventilatorraum 4 ein Ventilator 6 drehbar gelagert. Selbstverständ lich kann der Ventilatorraum auch in einem von dem Siebtrommelgehäuse 1 abgetrennten, hier nicht dargestellten, gesonderten Ventilatorgehäuse angeordnet sein. Jedenfalls setzt der Ventilator das Innere der Trommel 5 unter Saugzug. Auch ist die Trommelkonstruktion an einer Nassbehandlungsvorrichtung, die auch nur zum Absaugen von Flüssigkeit dienen kann, Gegenstand des Patentes. Die Gesamtkonstruktion ist dann entsprechend anzupassen.A screen drum device basically consists of an approximately rectangular housing 1, which is subdivided by an intermediate wall 2 into a treatment space 3 and a fan space 4. In the treatment room 3, the screening drum 5 and concentra- a fan 6 rotatably mounted to this in the fan room 4. Of course, the fan room can also be arranged in a separate from the screen drum housing 1, not shown here, separate fan housing. In any case, the fan sets the interior of the drum 5 under induced draft. The subject matter of the patent is also the drum construction on a wet treatment device, which can also serve only for sucking off liquid. The overall construction is then adjusted accordingly.
Gemäß der Fig. 1 sind ober- und unterhalb des Ventilators 6 jeweils Heizaggregate 7 angeordnet, die aus mit Heizmedium durchflossenen Rohren bestehen. Die Siebtrommel ist in dem nicht vom Textilgut 9 bedeckten Bereich innen von einer Innenabdeckung 8 gegen den Saugzug abgedeckt. Die wirksame Haut der Siebtrommel ist durch die weiter unten beschriebene Blechstreifenstruktur nach Fig. 2 gebildet. Diese ist außen von einem feinmaschigem Sieb 19 umschlungen, das an der Stirnseite der Trommel an den beiden Böden 1 1 , 12 gespannt gehalten ist.According to FIG. 1, heating units 7 are arranged above and below the ventilator 6 and consist of tubes through which heating medium flows. The screen drum is covered in the area not covered by the fabric 9 inside by an inner cover 8 against the induced draft. The effective skin of the screen drum is formed by the sheet metal strip structure of FIG. 2 described below. This is wrapped on the outside by a fine-meshed sieve 19, which is held taut on the end face of the drum at the two bottoms 1 1, 12.
Die vorbekannte Blechstreifenstruktur besteht aus axial ausgerichteten Blechstreifen 10, deren radial ausgerichtete Höhe aus Fig. 2 hervorgeht. Damit liegt also der sieb- förmige Belag 19 nur auf den radial außen angeordneten Kanten der Blechstreifen 10 auf. Die Blechstreifen 10 sind mit einem definierten Abstand nebeneinander an den beiden Böden 11 , 12 durch nicht dargestellte Schrauben befestigt. Damit dieser Abstand über die Breite der Trommel fixiert ist, sind als Abstandhalter dienende, im ganzen mit 20 bezeichnete Verbindungselemente vorgesehen, die mittels Schrauben 29, 29' und 30, 30' mit den Blechstreifen 10 verbunden sind.The previously known sheet metal strip structure consists of axially aligned sheet metal strips 10, the radially aligned height of FIG. 2 shows. Thus, the sieve-shaped covering 19 rests only on the radially outer edges of the sheet-metal strips 10. The metal strips 10 are attached at a defined distance next to each other on the two floors 11, 12 by screws, not shown. So that this distance is fixed over the width of the drum, serving as spacers, designated as a whole with 20 connecting elements are provided, which are connected by means of screws 29, 29 'and 30, 30' with the sheet metal strip 10.
Die Verbindungselemente 20 weisen gemäß Fig. 2 an ihren Anlageflächen an den Blechstreifen 10 einen rechteckigen Flansch 22 auf. Der radial außen sich erstreckende Bereich des Verbindungselementes 20 besteht aus dem Steg 24. Radial innen weist das Verbindungselement 20 einen verbreiterten Fuß 28 auf, während der übrige Bereich 26 des Verbindungselementes mit Ausnahme in Höhe der Schrauben - durchgänge 25, 27 schmal im Querschnitt ausgebildet ist. Die Verbindung der Verbindungselemente 20 untereinander erfolgt mittels Stangen 29, 29' und 30 30' mit Gewinden zumindest an den beiden Enden, auf die dann die Muttern 31 innerhalb eines Verbindungselementes 20' aufgeschraubt werden. Das neue Verbindungselβment 20" nach Fig. 3 und 4 ist über seine radiale Erstreckung insgesamt stromlinienförmig ausgebildet. Es weist an seinen beiden mit den Bohrungen 32, 33 versehenen Enden eine radial gerichtete Pfeilspitze 34, 35 auf, die dem vorbeiströmenden Fluid weniger Widerstand bietet. Zwischen dem Bereich in Höhe der Bohrungen 32, 33 verbleibt das Verbindungselement 20" unverändert breit entsprechend der Breite wie sie für die Bohrungen 34, 35 nötig ist. Infolge dieser Formgebung des Verbindungselementes 20" ist keine Kante oder Rille mehr vorhanden, die Anlass für eine Verschmutzung geben kann.The connecting elements 20 have according to FIG. 2 at their contact surfaces on the sheet metal strip 10 a rectangular flange 22. The radially outwardly extending region of the connecting element 20 consists of the web 24. Radially on the inside, the connecting element 20 has a widened foot 28, while the remaining region 26 of the connecting element, except for the screw passages 25, 27, is narrow in cross section , The connection of the connecting elements 20 with each other by means of rods 29, 29 'and 30 30' with threads at least at the two ends to which then the nuts 31 are screwed within a connecting element 20 '. The novel connecting element 20 "according to Figures 3 and 4 has an overall streamlined design over its radial extension, and at its two ends provided with the bores 32, 33 has a radially directed arrowhead 34, 35 which offers less resistance to the fluid flowing past. Between the area in the amount of holes 32, 33, the connecting element 20 remains "unchanged wide according to the width as it is necessary for the holes 34, 35. As a result of this shaping of the connecting element 20 "no edge or groove is present, which can give rise to pollution.
Um eine Gewichtsverminderung zu erzielen, ist in dem mittleren Bereich das Verbindungselement 20" mit einem Hohlraum 36 versehen, dessen nur der Stabilität genügenden Wandungen 37, 38 gleich dick und parallel verlaufen.In order to achieve a weight reduction, in the middle region, the connecting element 20 "is provided with a cavity 36, whose walls 37, 38, which only provide stability, extend in the same thickness and in parallel.
Die Querschnittsbreite der Wandungen 37, 38 in Höhe des Hohlraumes 36 entspricht etwa auch der Breite der Wandungen in Höhe der Bohrungen 32, 33, wie es aus der Fig. 4 zu entnehmen ist.The cross-sectional width of the walls 37, 38 in the amount of the cavity 36 corresponds approximately to the width of the walls in the amount of holes 32, 33, as can be seen from Fig. 4.
Das Verbindungselement gemäß Fig. 3, 4 ist aus Metall und aus einem Stück gegossen. Lediglich die Bohrungen 32,33 sind nachzuarbeiten. Zumindest an einer Stelle rund um die Trommel sind die einzelnen Schrauben 29, 30, deren Fuss mit einem Hohlgewinde und deren Kopf mit einem normalen in das Hohlgewinde passenden Dorngewinde versehen ist, durch ein sogenanntes Schloss zu einem Kreis zu verbinden. Zumindest an dieser einen Stelle hat die notwendige Mutterschraube einen größeren Durchmesser. Ein Verbindungselement gemäß Fig. 3 ist nicht mehr brauchbar. Zumindest an dieser Stelle kann zur Erfüllung der gestellten Aufgabe das Verbin- dungselement lediglich aus einem pfeilförmig gebogenen Blech bestehen, das die Wandstärke gemäß der Wandungen 37, 38 aufweist, a nsonsten aber zur Aufnahme des Schlosses hohl ist. The connecting element according to FIGS. 3, 4 is cast from metal and from one piece. Only the holes 32,33 are rework. At least at one point around the drum are the individual screws 29, 30, the foot of which is provided with a hollow thread and the head with a normal fitting into the hollow thread mandrel, to connect by a so-called lock to a circle. At least at this point, the necessary nut screw has a larger diameter. A connecting element according to FIG. 3 is no longer usable. At least at this point, to fulfill the task, the connecting element consist only of an arrow-shaped bent sheet metal, which has the wall thickness according to the walls 37, 38, but otherwise is hollow for receiving the lock.
