Description

Vorrichtung zum Fördern von pulverförmigen oder körnigen Stoffen auf luft- bzw. gasdurchlässiger Unterlage Es ist bekannt, daß sich pulverförmige Stoffe dadurch transportieren lassen, daß man durch eine luftdurchlässige Unterlage Luft oder Gas in den darüber befindlichen Transportraum einführt und das Material auf diese Weise über eine geeignete Fläche gleichsam zum Fließen bringt. Bei dieser Art pneumatischer Förderung kann es vorkommen, daß beispielsweise aus Materialbeschaffenheitsgründen der Neigungswinkel der Förderanlage verhältnismäßig groß sein muß, wenn der Guttransport nur durch die Fließendmachung des Gutes allein erfolgen soll. Man hat daher bereits Anordnungen getroffen,. bei denen die das Gut auflockernde Förderrinne auch noch in Schwingungen oder Rüttelbewegungen versetzt wird. L, Letzteres wird nach einem Vorschlag beispielsweise durch unbalante Wellen bewirkt, die funktionsmäßig mit dem Rinnenboden gekoppelt sind. Nach einem anderen Vorschlag, der sich jedoch nicht auf pneumatische Förderrinnen, sondern auf ein von einem Luftstrom durchblasenes Sichterschwingsieb bezieht, werden Elektromagneten als Schwingungserreger benutzt. Bei dieser letzteren Anordnung arbeiten zwei tischartig ausgebildete Schwingrahmen zusammen, die außerdem durch Federn gegenseitig gepuffert sind. Der luftdurchlässige Boden des Schwingtischsiebes wird dabei nicht unmittelbar, sondern durch einen Schwingrahmenmechanismus in rüttelnde Bewegung versetzt, der zusätzlich Platz beansprucht und beispielsweise für eine längere pneumatische Förderrinne nicht zu verwenden wäre.Device for conveying powdery or granular substances air or gas permeable base It is known that powdery substances can be transported by passing air through an air-permeable pad or gas introduces into the transport space above and the material on in this way, as it were, makes it flow over a suitable surface. At this Type of pneumatic conveying, it can happen that, for example, for reasons of material properties the angle of inclination of the conveyor system must be relatively large when transporting goods should only take place through the flow of the good alone. So you already have Orders made. where the conveyor trough loosening up the property is also still there is set in vibrations or shaking movements. L, the latter will be after a Proposal caused for example by unbalanced waves that functionally with are coupled to the channel bottom. According to another suggestion, which is not on pneumatic conveyor troughs, but on one blown through by an air stream Sifter vibrating sieve refers, electromagnets are used as vibration exciters. In this latter arrangement, two table-like oscillating frames work together, which are also mutually buffered by springs. The breathable one The bottom of the vibrating table screen is not created directly, but by a vibrating frame mechanism set in jarring motion that takes up additional space and, for example would not be used for a longer pneumatic conveyor trough.

Die Erfindung bezweckt demgegenüber die Verbesserung und Vereinfachung der elektromagnetischen Rüttelung bei einer pneumatischen Förderrinne in der Weise, daß ein Teil des schwingungs- erzeugenden Systems in die gas durchlässige oder poröse Unterlage selbst verlegt wird. Dies geschieht erfindungsgemäß dadurch, daß mit der porösen Unterlage vorzugsweise Stahldrähte od. dgl. fest verbunden sind, die mit geeignet angeordneten elektromagnetischen Erregern zusammenwirken, wodurch die poröse oder gasdurchlässige Unterlage der Förderrinne unmittelbar in Schwingungen versetzt wird. Die Stahldrähte können entweder in der porösen Unterlage materialumschlossen eingelegt oder auch daran in gewünschter Weise fest aufgebracht sein. Durch zweckentsprechende Anordnung der Elektromagneten lassen sich Vibrationserschütterungen der Rinne in jeder gewünschten Richtung herbeiführen. Die gasdurchlässige oder poröse Unterlage kann in an sich bekannter Weise aus mineralischem oder keramischem Material, wie Filtersteinen od. dgl;, oder auch aus Faserstoffen, wie beispielsweise Textilfasern, Glasfasern, Kunstharzfasern oder einer Kombination dieser Fasern, hergestellt sein. dadurch, daß ein Teil des schwingungserzeugenden Systems unmittelbar auf oder in die gasdurchlässige Unterlage selbst verlegt wird, ergibt sich eine überaus einfache und Platz sparende Anordnung, die - insbesondere bei größeren Förderrinnenlängen-in vorteilhaftester Weise zur Geltung kommt. In contrast, the invention aims to improve and simplify the electromagnetic vibration in a pneumatic conveyor chute in such a way that that part of the vibrational generating system in the gas permeable or porous underlay is laid by yourself. According to the invention, this is done by that steel wires or the like are preferably firmly connected to the porous base, which interact with suitably arranged electromagnetic exciters, whereby the porous or gas-permeable base of the conveyor trough vibrates directly is moved. The steel wires can either be enclosed in the material in the porous base inserted or firmly attached to it in the desired manner. By appropriate Arrangement of the electromagnets can vibrate the gutter in in any desired direction. The gas-permeable or porous pad can in a manner known per se from mineral or ceramic material, such as Filter stones or the like, or made of fibrous materials, such as textile fibers, Glass fibers, synthetic resin fibers or a combination of these fibers. in that a part of the vibration generating system is directly on or in If the gas-permeable underlay is laid itself, the result is an extremely simple one and space-saving arrangement, which - especially with larger conveyor trough lengths - in comes into its own in the most advantageous way.
