Description

2020th

Die Erfindung betrifft einen regenerativen Wärme- und/oder Feuchtigkeitstauscher für zwei Luftströme, einen Primärstrom und einen Sekundärstrom, der einen einen Kontaktkörper enthaltenden Rotor mit in axialer Richtung offenen Kanälen umfaßt, durch welche die beiden Luftströme in voneinander getrennten Zonen im Gegenstrom hindurchgehen, wobei zwischen dem Rotor und dem Gehäuse die Luftströme trennende, senkrecht zur Rotoroberfläche verschiebbare Dichtungsleisten vorgesehen sind.The invention relates to a regenerative heat and / or moisture exchanger for two air flows, a primary current and a secondary current, which has a rotor containing a contact body in an axial direction In the direction of open channels, through which the two air flows in separate zones go through in countercurrent, whereby between the rotor and the housing the air flows separating, Sealing strips which can be displaced perpendicular to the rotor surface are provided.

Wie bekannt dienen solche Wärmetauscher (US-PS 1 586 817) zur Erwärmung dei Primärluft mit der von der Sekundärluft abgegebenen Wärme. Dabei soll nach Möglichkeit vermieden werden, daß verbrauchte Sekundärluft in den zu belüftenden Raum strömt. Um die Verluste und Falschluftmengen möglichst gering zu halten, sollen die Spalte zwischen den Luftkanälen und dem sich drehenden Kontaktkörper möglichst klein sein.As is known, such heat exchangers (US Pat. No. 1,586,817) are used to heat the primary air with that of heat given off by the secondary air. It should be avoided as far as possible that used secondary air flows into the room to be ventilated. In order to keep the losses and false air volumes as low as possible, the gaps between the air ducts and the rotating contact body should be as small as possible be.

Bei einem Regenerator (CH-PS 276 522) ist deshalb auch bekannt, die Spaltverluste durch Dichtungsleisten zu vermeiden, die im Gehäuse geführt und durch Federn an die Rotoroberfläche angedrückt werden. Außer dem Verschleiß der Dichtungsleisten, die dann regelmäßig ersetzt werden müssen, ist mit dieser Anordnung vor allem der Nachteil verbunden, daß durch das ständige Andrücken der Dichtungsleisten die Rotoroberfläche beschädigt wird, da die Kanalwandungen des Kontaktkörpers aus empfindlichem Werkstoff, beispielsweise Asbestpapier hergestellt sind.In a regenerator (CH-PS 276 522) it is therefore also known that the gap losses through sealing strips to avoid that are guided in the housing and pressed against the rotor surface by springs. Apart from the wear and tear of the sealing strips, which then have to be replaced regularly, this arrangement is also possible mainly associated with the disadvantage that the constant pressing of the sealing strips The rotor surface is damaged because the duct walls of the contact body are made of sensitive material, for example asbestos paper are made.

Der Erfindung liegt deshalb die Aufgabe zugrunde, dif? Vorrichtung der eingangs geschilderten Art mit einer derartigen Dichtung zu versehen, die verschleißarm arbeitet und Beschädigungen der Rotoroberfläche vermeidet.The invention is therefore based on the object of dif? Device of the type described above with to provide such a seal that works with little wear and damage to the rotor surface avoids.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß die Dichtungsleisten mittels parallel zur Rotoroberfläche aus federnder Halter an senkrecht zur Rotoroberfläche verlaufenden Flanschen befestigt sind.This object is achieved according to the invention in that the sealing strips by means of spring-loaded holders parallel to the rotor surface are perpendicular to the Flanges extending across the rotor surface are attached.

Damit werden die Dichtungsleisten nicht ständig gegen die Rotoroberfläche gedrückt. Bei Inbetriebsetzen des Rotors werden die Dichtungsleisten vielmehr aus einer gegen die Rotoroberfläche zu vorgeschobenen Lage von dem sich drehenden Rotor soweit zurückgeschoben« daß sich unter nv.«(gehender Anpassung an die Rotoroberfläche ein leichtes Spiel einstellt und eine gute Abdichtung vermittelt wird. Durch die parallel zurThis means that the sealing strips are not constantly pressed against the rotor surface. When commissioning of the rotor, the sealing strips are rather pushed forward against the rotor surface Position of the rotating rotor pushed back so far that "under nv." (Going adaptation to the rotor surface sets a slight play and a good seal is imparted. Through the parallel to the Rotoroberfläche federnde Halterung der pichtungslel· sten lassen sich diese leicht einstellen, sind aber andererseits ausreichend fest gehaltert.These can easily be adjusted, but on the other hand are held sufficiently firmly on the rotor surface.

Ein Ausführungsbeispiel der Erfindung ist nachstehend an Hand der Zeichnung näher erläutert. Es zeigtAn embodiment of the invention is explained in more detail below with reference to the drawing. It shows

F i g. 3 eine perspektivische Ansicht der mit der Vorder- und Rückseite des Rotors zusammenwirkenden Dichtungsleisten,F i g. 3 is a perspective view of the front sealing strips interacting with the rear of the rotor,

Das Gehäuse 10 in F i g. 1 besteht aus zwei parallelen Stirnwänden 12 und 14, zwischen denen ein über einen Motor 64, Getriebe 66, Riemenscheibe 68 und Riemen 70 angetriebener Rotor vorgesehen ist, der in F i g. 2 mit 32 bezeichnet ist. Die Außenseite der Stirnwände ist mit seitlichen Blechen 16 mittels Schrauben 15 miteinander verbunden. Die Stirnwände sind mit einander gegenüberliegenden kreisrunden öffnungen 19 versehen, die durch vier um 90° gegeneinander versetzte Speichen 20 in Sektoren aufgeteilt sind. In lotrechter Richtung ergibt sich somit eine Aufteilung in zwei Hälften. Durch die eine Häifte strömt die Primärluft (Frischluft) und durch die andere Hälfte die austretende Sekundärluft (verbrauchte Raumluft). Über an den Stirnwänden befestigte Rohrstücke 22. 26, 28 und 30 werden die Kanäle für die Primär- und Sekundärluft angeschlossen.The housing 10 in FIG. 1 consists of two parallel End walls 12 and 14, between which a motor 64, gear 66, pulley 68 and Belt 70 driven rotor is provided, which is shown in FIG. 2 is designated by 32. The outside of the end walls is connected to one another with side plates 16 by means of screws 15. The end walls are with opposing circular openings 19 provided, which are offset by four by 90 ° from one another Spokes 20 are divided into sectors. In the vertical direction there is thus a division into two halves. The primary air (fresh air) flows through one half and the secondary air exiting (used room air) through the other half. About to Pipe sections 22, 26, 28 and 30 attached to the end walls become the channels for the primary and secondary air connected.

Der Rotor besteht aus einem auf einer Nabe sit/enden Kontaktkörper, der aus Schichten zusammengesetzt ist, welche enge in axialer Richtung durchlaufende Kanäle 98 bilden. Um den Außenumfang des Kontaktkörpers ist ein Band 36 gelegt. Die Achse des Rotors ist in einer von den Speichen 20 gebildeten mittleren Plat te 41 gehalten.The rotor consists of a sit / end on a hub Contact body, which is composed of layers, which narrow traversing in the axial direction Form channels 98. A band 36 is placed around the outer circumference of the contact body. The axis of the rotor is in a middle plate formed by the spokes 20 te 41 held.

Längs der Ränder des Rotors sowie zwischen den Sekundär- und Primärluftzonen des Austauschers sind Dichtungsleisten 54 vorgesehen, die am deutlichsten in F1 g. 2 und 3 dargestellt sind. Die Dichtungsleisten sind mittels federnder Halter 56 und Schrauben 58 an einem Flansch 60 der Stirnwand 14 befestigt. Die Dichtungsleisten 54 können beispielsweise aus Kork, Fasern, Asbest oder Kunststoff bestehen; sie werden in einem Abstand voneinander mittels der federnden Halter in ihrer Lage gehalten. Dies ist besonders deutlich auch aus F i g. 1 zu entnehmen. Beim Einbau haben die Dichtungsleisten in den Haltern eine gewisse Bewegungsfreiheit. Wenn der Rotor 32 eingebaut wird, dann können die Dichtungsleisten, welche in die Halter eingesetzt sind, zurückgezogen sein. Nach dem Einsetzen des Rotors lassen sie sich dann von Hand gegen die ebene Rotoroberfläche verschieben. Dank ihres federnden Einbaues können sich die Dichtungsleisten selbsttätig auf unvermeidbare Schrägstellungen einstellen, so daß sie mit einem kleinen Spalt Ober den ganzen Umkreis herum und entlang der radialen Teilungswände dichtend gegen den Rotor anliegen. Sealing strips 54 are provided along the edges of the rotor and between the secondary and primary air zones of the exchanger, which are most clearly shown in FIG. 2 and 3 are shown. The sealing strips are fastened to a flange 60 of the end wall 14 by means of resilient holders 56 and screws 58. The sealing strips 54 can for example consist of cork, fibers, asbestos or plastic; they are held in their position at a distance from one another by means of the resilient holders. This is particularly clear from FIG. 1 can be found. During installation, the sealing strips in the holders have a certain freedom of movement. When the rotor 32 is installed, the sealing strips which are inserted into the holders can be withdrawn. After inserting the rotor, they can then be moved by hand against the flat rotor surface. Thanks to their resilient installation, the sealing strips can automatically adjust to unavoidable inclinations, so that they lie sealingly against the rotor with a small gap over the entire circumference and along the radial dividing walls.

Die Umlaufrichtung des Rotors erfolgt vorzugsweise in Richtung des Pfeiles 62 nach F i g. 2. Bei dieser Umlaufrichtung geben die Dichtungsleisten infolge des Ausfederns der Halter 56 nach, wenn sie beispielsweise beim Einsetzen des Austauschers mit dem Rotor unmittelbar in Berührung kommen. Hierdurch wird vermieden, daß die Dichtungsleisten Schaden nehmen oder Schichten des Rotors beschädigt werden.The direction of rotation of the rotor is preferably in the direction of arrow 62 according to FIG. 2. In this direction of rotation give the sealing strips as a result of Rebound of the holder 56 after, for example, when they come into direct contact with the rotor when inserting the exchanger. This prevents the sealing strips from being damaged or damaged Layers of the rotor are damaged.

Um die Riemenscheibe 68 und das zylindrische Band 36 des Rotors ist der Riemen 70 gespannt. Die Drehiah! des Rotors kann in der Größenordnung von 10 U/min liegen.The belt 70 is stretched around the pulley 68 and the cylindrical belt 36 of the rotor. The Drehiah! of the rotor can be of the order of 10 rpm.

An der Seite des Rotors, an der die von den Rohr- s stücken 26 und 28 gebildeten getrennten Strömungsdurchlässe vorgesehen sind, sind sowohl ober als auch unter der Mittelplatte 41 verhältnismäßig schmale Speichen vorgesehen, die in F i g. 3 dargestellte Dichtungsleisten 74 tragen und die miteinander mittels eines to halbkreisförmigen Leistenteiles 75 längs des Flansches der Mittelplatte 41 miteinander verbunden sind. Auf der entgegengesetzten Seite ist unterhalb der Mittelplatte eine ähnlich schmale Speiche vorgesehen, mit der eine Dichtungsleiste ?6 zusammenarbeitet. Ober- !5 halb der Rotorachse ist die Speiche 78 zu einem Sektor erweitert, der sich mit gleichbleibender Form peripherisch an der lotrechten Speiche 72 auf der anderen Seite des Rotors vorbei erstreckt. Die sektorenförmige Speiche 78 wirkt mit zwei Dichtungsleisten 80, 82 zusammen, die miteinander und mit der unteren Dichtungsleiste 76 durch einen teilkreisformigen, auf der Mittelplatte 41 sitzenden Leistenteil 84 verbinden sind. Hierdurch wird eine doppelte Reinblaszone zwischen den Sekundär- und PrimBrluftzonen in dem Austauscher gebildet. Wenn sich der Rotor in Richtung des Pfeiles 62 nach F i g. 2 bevyegt und durch die linke, von den Rohrstücken 22,26 gebildete Sekundärluftzon.e ein Sekundarluftstrom geführt wird, werden in diesem Sekundärluftstrom vorhandene Wärme und Feuchtigkeit an die Schichten des Rotors abgegeben, wobei mit Hilfe der Dichtungsleisten eine sichere Leitung der Luftströme gewährleistet ist.On the side of the rotor on which the separate flow passages formed by the pipe sections 26 and 28 are provided, relatively narrow spokes are provided both above and below the center plate 41, which are shown in FIG. 3 carry the sealing strips 74 shown and which are connected to one another by means of a semicircular strip part 75 along the flange of the center plate 41. On the opposite side, below the middle plate, a similarly narrow spoke is provided, with which a sealing strip? 6 cooperates. Top! 5/2 of the rotor axis is the spoke 78 extends to a sector which is peripherally on the other side of the rotor extends with uniform shape on the vertical spoke 72 over. The sector-shaped spoke 78 interacts with two sealing strips 80, 82 which are connected to one another and to the lower sealing strip 76 by a part-circular strip part 84 seated on the center plate 41. This creates a double blow-in zone between the secondary and primary hot air zones in the exchanger. When the rotor moves in the direction of arrow 62 according to FIG. 2 moved and a secondary air flow is passed through the left-hand secondary air zone formed by the pipe sections 22, 26, heat and moisture present in this secondary air flow are given off to the layers of the rotor, with the help of the sealing strips ensuring that the air flows are safely guided.

Die Dichtungsleisten weisen kreisrunde Leistenteile 94,96(Fi g. 3) auf, die sich längs des Umfanges des Kontaktkörpers des Rotors 32 erstrecken, und zwar derart, daß einer Leckage auf diesem Wege vorgebeugt wird. Die gewählte Bauart der Dichtungsleisten mit axial verschiebbaren, leicht zugänglichen und einstellbaren Dichtungsleisten bringt es mit sich, daß die ortsfesten Teile des Austauschers nicht mit sehr hoher Genauigkeit bearbeitet oder eingebaut zu werden brauchen. Etwaige Ungleichheiten im Spielraum zwischen dem Rotor und den die Dichtungsleisten tragenden Teilen werden auf einfache Weiie beim abschließenden Einstellen der Dichtungsleisten gegenüber dem Rotor ausgeglichen.The sealing strips have circular strip parts 94,96 (Fi g. 3), which extend along the circumference of the Contact body of the rotor 32 extend, in such a way that a leak is prevented in this way will. The selected type of sealing strips with axially displaceable, easily accessible and adjustable sealing strips means that the stationary Parts of the exchanger do not need to be machined or installed with very high accuracy. Any inequalities in the clearance between the rotor and the one that supports the sealing strips Parts are made easy when the sealing strips are finally adjusted in relation to the rotor balanced.
