Description

Trommeltrockner mit Z-förmigen Rieseleinbauten Bei den im: Gleichstrom arbeitenden Trommeltrocknern, bei denen dme Heizgase, beispielsweise Feuergase, unmittelbar @ äuf das Trockengut einwirken, tritt die Trocknung um so rascher :ein, je feiner .die zu trocknenden Stoffe zerteilt sind. Die staubförmigen Biestandteile trocknen daher ain schnellsten, und es entsteht die Gefahr, daß sie von denn durchziehenden Gasen als Staub fortgeführt werden, was einesteils Stoffverlust, anderenteils Belästigung der Nachbarschaft durch austretenden. Staub und deshalb ko:stspidige Anlagen zur Verhinderung der Staubbildung zur Folge hat. Mit höheren Temperaturen der Heizgase nimmt die Trockenzeit zwar ab, es zeigt sich aber dabei .sehr bald eine Grenze, wenn, wie beispielsweise bei Kohle, das Trokkengut brennbar und leicht entzündlich ist. Man sieht sich daher gezwungen, größexle Geschwindigkeit bei niefixiger Temperatur d!ex Heizgase zu wählen, muß dann aber die Fallhöhe des Gutes bei der Drehung der Trockner soviel wie, möglich vermindern.Drum dryer with Z-shaped trickle installation For the im: direct current working drum dryers, in which dme heating gases, for example fire gases, have an immediate effect on the dry goods, the drying occurs all the faster: the finer the fabrics to be dried are divided. The powdery beer components therefore dry up the fastest, and there is a risk that they will pass through Gases are carried on as dust, which on the one hand is a loss of material and on the other is a nuisance the neighborhood by exiting. Dust and therefore costly systems for Prevention of dust formation. With higher temperatures of the heating gases the dry season decreases, but there will soon be a limit, if, for example with coal, the dry goods are flammable and easily ignitable is. One therefore sees oneself compelled to work at great speed at an unstable temperature d! ex heating gases must then be the height of fall of the goods when turning the Reduce dryer as much as possible.

Man hat deshalb; Einbauten xn den Trockentrommeln angebracht, die .entweder der Länge nach durchgehende Zellen bilden, in denen das Trockengut bei -der Drehung der Trommel herabrieselt, dabei aber von dem Gut in den Nachbarzellen vohkommen abgeschlossen ist, oder solche, die aus miteinander nicht in Berührung stehendien ProfilstÄben von kreuz-, stern- oder Z-fö@rnigem Querschnitt bestehen, .so daß keine gegeneinander abgeschlossenen Zellen gebildet werden und die entstehenden Brüllen sich irr: ganzen Trockner ausbreiten können, ein. Ausgleleh der Brüllen also unbehindert .stattfindet. Beide Formen der Einbauten haben aber Nachteile. Die erstgenannte Art den, daß ,ein. se lcher Brütdenausgleich nicht möglich ist, die zweite aber den, da,ß das Trockengut :dauernd von den Kanten der Einbaustäbe abfällt und daher eine starke Staubbildung di:e Folge isst.One therefore has; Internals xn the dryer drums mounted, the 'either longitudinally continuous cells form in which the dried material at - rotation of the drum trickles down, but this completed vohkommen of the well in the adjacent cells, or those that are not used in contact with each other Profiled bars of cross, star or Z-shaped cross-section exist, so that no mutually closed cells are formed and the resulting roar can spread to the whole dryer. The roar takes place unhindered. However, both forms of built-in components have disadvantages. The former type the that, a. This equalization of the vapors is not possible, but the second is because the dry material constantly falls off the edges of the built-in rods and therefore creates a lot of dust as a result.

Diese Mängel werden :durch den Gegenstand der Erfindung beseitigt, die in dem Einbau von im Querschniltt Z-förmigen Elementen besteht, die zwar nicht rnn:teinander in Berührung stehen, sondern so angeordnet sind, daß'im, Querschnkt quaidratis!che Längs- kanäle entstehen, die aber rächt gegen. die Nachbarkaniäle abgeschlossen sind, aus denen das Trockengut aber. auch nicht in die ande- ren Übertreten kann und in denen esohne freien Fall aus geringster Höhe ohne Staub- aufwirbelung entlangrieselt, so da:ß die Vor- teile beider bekannter Ebbauarten mitein- ander vereinigt sind. Auf der Zeichnung isst' ein Trommeltrock- ner mit den neuen Einbauten irn Querschnitt dargestellt. a ist der Mantel des auf den Lauf- und Tragrollen b in der PfeälriicMung umlandenden Trockners. In diese zylindrische Trommel sind irn Querschnitt Z-förmige, aus einem Mittelsteg d und zwei Schenkeln e beste- hende Gebilde so eingebaut, daß, die freien Schenkel der Umdrehungsrichtung des Trock- ners entgegengerichtet sind. Dabei. sind die Einbaukörper so gegeneinander angeordnet, daß die Fläche von je vier Einbaukörpern eine Gruppe bildet und einen im allgemeinen quadratischen Raum umschließt, wobei zwi- schen den Stegen und Schenkeln der Ele- mente ,überall ein für den. Durchtritt der Luft :oder Heizgase genügender Raum frei: bleibt. Bei. der Drehung des Trockners macht das auf den Einbaukörpern liegende Trockengut innerhalb jeder Gruppe von vier Körpern einen Kreislauf entgegengesetzt der Dreh- richtung des Trockners und gleitet dabei. auf den 'Flächen der Einbaukörper ohne freien Fall entlang, so daß :die Neigung zur Staub- bildung auf das geringste Maß gemindert ist. Die Staubbildung hängt letjglieh von der Stärke des den Trockner dlurchziehenden Gas- stromes ab. These deficiencies are: eliminated by the subject matter of the invention, which consists in the incorporation of cross-sectional Z-shaped elements which are not in contact with each other but are arranged in this way are that 'in the cross section quaidratic longitudinal channels emerge, which, however, avenge them. the Adjacent channels are completed from which but the dry goods. not even in the other can and in those without free fall from the smallest height without dust vortex trickles along, so that: ß the parts of both well-known types of ebb are united with one another. In the drawing, a drum skirt is eating with the new internals in cross-section shown. a is the coat of the on the barrel and Land the support rollers b in the arrows Dryer. In this cylindrical drum are Z-shaped in cross-section, made of one Middle bar d and two legs e existing structures built in such a way that, the free Leg of the direction of rotation of the drying ners opposite to sin d. Included. are the Built-in bodies so arranged against each other, that the area of four built-in bodies forms a group and one in general enclosing a square space, whereby between between the webs and legs of the ele- ments, one for them everywhere. Passage of the Air: or heating gases sufficient space free: remain. At. the rotation of the dryer does that Dry goods lying on the installation units within each group of four bodies a cycle opposite to the rotary direction of the dryer and slides. on the 'surfaces of the built-in body without free So that: the tendency to dust education is reduced to the smallest degree. The dust formation depends largely on the Strength of the gas passing through the dryer Stromes from.
