Abstract

Filter bag comprises a wall end closures which are smooth and/or bowed. The bag has a large filter surface area combined with a small size. The filter is pref. conical or cylindrical and its radical extensions are of rounded or angled cross-section. The bowed end closure and opposite end closure are both provided with sprays to vibrate the filter and cause cake to be thrown towards housing discharge mechanism.

Description

Beschreibung und Erläuterung zurDescription and explanation of the

P a t e n t a n m e l d u n g "Kleinbauender Filter, vorzugsweise für den Bergbau mit radialprofiliertem Filtermatericl11.P a t e n t a n t a n m e l d u n g "Small filter, preferably for mining with radially profiled filter material 11.

Für den Bergbau, für den Tunnelbau und auch für viele Betriebes in denen nur beengte Platzverh.ltraisse zur Verfügung stehen, ist es erforderlich, die Geräte zur Filterung der Luft oder der Abgase klein il Es ii' vorschläge 1»ekannt, nach denen die Filter in besonderer Taschenform oder rohrförmiger Sternfilterprofilierung ausgebildet sein sollen.For mining, for tunneling and also for many operations in where only limited space is available, it is necessary to the devices for filtering the air or the exhaust gases are known, according to which the filters in a special pocket shape or tubular star filter profile should be trained.

Diese bekannten, beengt bauenden Filterformen, besonders die Sternfilterform, haben den Nachteil, daß die Abdichtung des Sternfilters aufgrund der profilierten Stern form unten und oben an den abdichtenden Deckel-oder Flanschflächen in Kunststoff oder Gummi eingeliert oder einvulkanisiert werden müssen.These well-known, cramped filter shapes, especially the star filter shape, have the disadvantage that the sealing of the star filter due to the profiled Star shape at the bottom and top of the sealing lid or flange surfaces in plastic or rubber must be embedded or vulcanized.

Diese Art der Abdichtung oder des Ansatzes eines Verbindungsflansches a) ist sehr aufwendig und somit teuer und b) besteht aus 2 verschiedenen Materialien, die zusammengebracht werden müssen, die in der Alterungsbeständigkeit und auch in der Beanspruchung bei der Reinigung z. B. durch Luftstoß sich aufgrund Ihrer Zusammensetzung anders verhalten und somit nach relativ kurzem Einsatz zu Alterungsbrüchen und Lösungserscheinungen führen.This type of sealing or the approach of a connecting flange a) is very complex and therefore expensive and b) consists of 2 different materials, which have to be brought together, which in aging resistance and also in the stress at the Cleaning z. B. by blast of air due to Their composition behaves differently and thus increases after a relatively short period of use Aging fractures and loosening lead.

Diese bekannten Sternfilter mit anvulkanisierten oder angelierten Endstücken lassen sich für die Absaugung von Heißgas z. B. Kraftwerksabgasen nicht benutzen, da die Flanschmaterialien z. B. aus Gummi oder Kunststoff den Temperaturen von z. B. 200° C nicht gewachsen sind.These known star filters with vulcanized or gelled End pieces can be used for the extraction of hot gas z. B. power plant emissions are not use, as the flange materials z. B. rubber or plastic the temperatures from Z. B. 200 ° C have not grown.

Um einen kleinbauenden Filter mit größtmöglicher Oberfläche gestalten zu können, ohne eine eingelierte oder einvulkanisierte Flansch- oder Deckelabdichtung notwendig zu machen, wird erfindungsgem vorgeschlagen, eine Filterbduform entsprechend beiliegender Zeichnung zu benutzen.To design a compact filter with the largest possible surface without an embedded or vulcanized flange or cover seal To make necessary, it is proposed according to the invention, a Filterbduform accordingly to use the enclosed drawing.

In der beiliegenden Zeichnung ist dargestellt: mit 1) der rohr- oder taschenförmige filternde Körper, mit 2) die erfindungsgemäß ausgeführten radialangeordneten, profilierten Rohre oder Filtertaschen, mit 3) eine Formgebung der Radialprofile z. B. symmetrisch oder asymmetrisch bzw. Rund- oder Trapezform, die wulstförmig den filternden Körper umläuft, mit t) der flanschförmige Deckel oder Flanschanschluß, der in einfachsterweise aus dem gleichen Material umgelsantet, angenaht oder mit temperaturfestem Material mechanisch verbunden sein kann, 5) zeigt eine konische Rohrform, Gt zeigt das Filtergehäuse, 7) zeigt eine Versteifungsanordnung der profilierten Filtergewebe z. B. Innendrahtkorb und 8) einen Außendrahtkorb.The accompanying drawing shows: with 1) the pipe or pocket-shaped filtering body, with 2) the radially arranged according to the invention, profiled tubes or filter bags, with 3) a shaping of the radial profiles z. B. symmetrical or asymmetrical or round or trapezoidal shape, the bead-shaped revolves around the filtering body, with t) the flange-shaped cover or flange connection which, in the simplest possible way, is made of the same material, sewn or mechanically connected with temperature-resistant material, 5) shows a conical tube shape, Gt shows the filter housing, 7) shows a stiffening arrangement the profiled filter fabric z. B. inner wire basket and 8) an outer wire basket.

Zwischen diesen Drahtkörben wird das profilierte Filtertaschengewebe gehalten. The profiled filter pocket fabric is placed between these wire baskets held.

9) stellt verschiedene Arten des Staubtransportes aus dem Filtergehause dar, z. B. Kratzband- oder Schneckenförderer, 10) zeigt Luftdüsen, die zum impulsförmigen Druck~ luftstoß oder Spüllufteingabe in das rohr- oder taschenförmige Filter einleiten zur Abreinigung der auf das profilierte Filtermaterial aufgelagerten Staubteilchen. 9) provides different ways of transporting dust out of the filter housing represent, e.g. B. scraper belt or screw conveyor, 10) shows air nozzles, the pulse-shaped Introduce a blast of compressed air or purge air into the tubular or pocket-shaped filter for cleaning the dust particles deposited on the profiled filter material.

Selbstverständlich ist die Erfindung nicht auf die vorstehend dargestellte und beschriebene Ausbildungsform beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, einen kleinbauenden Filter vorzugsweise für den Untertage- und Tunnelbau so zu gestalten, daß er aus einem radialprofiliertem angeordnetem Filtermaterial besteht, vorzugsweise in ro'lrförmiger Taschenbauweise, wobei erflndungsgemaG; die Endstücke trotz der Profilierung glatte Anschlußflächen garantieren, die nicht wie bei den bekannten Sternfiltern nur durch Einvulkanisierung oder schwieriges Annuhen oder Ankleben der Sternfilterprofile an vorgefertigte andere Materialien notwendig ist, die zu Schwierigkeiten insbesondere in sehr heißen oder kalten Betriebspunkten ständig Anlaß geben.Of course, the invention is not limited to that presented above and described form of training, but there are numerous changes possible, without deviating from the basic idea, a compact filter preferably for underground and tunnel construction so that it consists of one radially profiled arranged filter material consists, preferably in a tubular pocket design, whereby according to the invention; the end pieces in spite of the Profiling guarantee smooth connection surfaces, which are not like the known ones Star filters only through vulcanization or difficult sewing or gluing the star filter profiles to prefabricated other materials is necessary that too Constant difficulties, especially in very hot or cold operating points To give reason.
