Abstract

The equipment aerates then compacts powdery and fine granular materials, e.g. meal, which is then packed in sacks of paper or plastic. It incorporates a sintered metal pipe whose porosity is selected to give the desired degree of permeability, and which can be of any desired length. The metal pipe is subjected to a vacuum from an exhauster PIPE, so as to draw the air out of the material. The powder is blown free by compressed air delivered via the exhauster pipe. The material is forced into the sack by a helical auger rotating in a round tube. The auger pitch becomes finer at the sintered pipe, tending to compact the aerated material and press it against the pipe by centrifugal force.

Description

zum Entlüften und Verdichten von pulverförmigen undfor venting and compressing powdery and

feinkörnigen Produkten(z. B. Mehle) die rasch in Säcke (z. B.fine-grained products (e.g. flour) which are quickly put into sacks (e.g.

Plastiksäcke oder Papiersäcke) abgefüllt werden Beschreibung dieser Maschinenanlage: Anmeldung vom 9. Gezember 1975 Die Sackpackpresse dient zum raschen Abfüllen von Mehlen, die mehr oder minder stark mit Luft angereichert sind in luftdichte Säcke.Plastic bags or paper bags) are filled with description of this Machinery: Registration dated December 9, 1975 The bag press is used for rapid Filling of flours that are more or less heavily enriched with air in airtight Bags.

Dieser Abpackvorgang wird mit einer Packmaschine dargestellt, die wie folgt aussieht: An der Oberseite der Maschine befindet sich ein Trichter, wo das abzupackende Mehl zuläuft. Dieser Trichter mündet in ein rundes Rohr. Dieses Ablaufrohr wird von einem zusätzlichen Rohr, dessen Durchmesser ca. 10 mm grösser ist, eingeschlossen.This packing process is shown with a packing machine that looks like this: At the top of the machine there is a funnel where the flour to be packed is running in. This funnel ends in a round tube. This The drain pipe is connected to an additional pipe, the diameter of which is approx. 10 mm larger is included.

An der Unterseite des eingeschlossenen Rohres wird ein Sintermetallrohr mit ca. 15 cm Höhe eingepasst. Beide Rohre werden durch einen Metallring an der Unterseite arretiert und gleichzeitig luftdicht abgeschlossen. Durch die Abdichtung der beiden übereinander gesteckten Rohre ist es mittels eines Hochdruckgebläses möglich, Luft durch das Sintermetall hindurch über das doppelwandige Rohr abzusaugen.A sintered metal tube is attached to the underside of the enclosed tube fitted with a height of approx. 15 cm. Both tubes are attached to the by a metal ring Locked underside and at the same time sealed airtight. Through the seal of the two pipes placed one on top of the other, it is done by means of a high-pressure blower possible to suck air through the sintered metal via the double-walled tube.

In der Packpresse läuft eine Schnecke, die das in den Fülltrichter einlaufende Mehl an dem besaugten Sintermetall vorbei, in das PackstUck druckt.A screw runs in the packing press, which feeds this into the filling funnel incoming flour past the vacuumed sintered metal, into which the package prints.

Das Packstuck (Papier- oder Plostivksocke) werden mittels einer Sackschnalle an einen Schlitten angehängt. Der Schlitten, der sich je nach dem Befüllungsgrad des Sackes nach unten bewegt, wird über stabile Gurte, die an einer Querachse befestigt sind gehalten, Ist der Schlitten ganz nach unten gedruckt und somit der Sack mit dem Mehl gefüllt, ist der Packvorgang abgeschlossen. Mit der Beendigung des Packvorganges schaltet sich die Packschnecke, die über einen Motor oder Transmission angetrieben wird, aus. Gleichzeitig wird die Besaugung des Sintermetalls unterbrochen. Nach Beendigung des Packvorganges kann der Sack durch Öffnen der Sackschnalle abgehängt werden. Nachdem ein neuer Sack an den Sackschlitten, der ueber die Sackschnalle befestigt wurde, angehängt ist, wird der Schlitten nach oben gezogen, sodass sich der Sackboden an der Unterseite des Rohres, wo die Packschnecke läuft, befindet. lurch Einschalten der Packschnecke und durch Einschalten des Besaugungsgebloses, wodurch über das Sintermetall die Luft aus dem Mehl evakuiert wird, kann der neue Packvorgang beginnen.The package (paper or plottive sock) is attached to a sledge using a sack buckle. The carriage, which moves downwards depending on the degree of filling of the sack, is held by stable straps that are attached to a transverse axis When filled with flour, the packing process is complete. When the packing process is finished, the packing screw, which is driven by a motor or transmission, switches off. At the same time the suction of the sintered metal is interrupted. After the packing process has been completed, the sack can be unhooked by opening the sack buckle. After a new sack has been attached to the sack sledge, which has been attached to the sack buckle, the sled is pulled upwards so that the bottom of the sack is on the underside of the tube where the screw conveyor runs. The new packing process can begin by switching on the packing screw and switching on the suction freezer, which evacuates the air from the flour via the sintered metal.

Claims

Device for venting and compressing powdery and fine-grained ones Products (e.g. flour) which are quickly filled into socks (e.g. plastic or paper bags) claims for the patent application dated December 9, 1975: machines and devices for compressing bulk materials are well known. What is new is that according to the invention Registered ventilation of powdery, fibrous and flaky bulk materials at Packing and compacting in airtight bags.

The claim relates to: 1. the installation of a sintered metal tube, whose porosity is different depending on the desired permeability and the length of which can be selected as required.

2. This sintered metal is placed under vacuum via an air duct, so that air is sucked out of the bulk material.

3. The sintered metal must be able to be blown free with compressed air.

The compressed air is fed into the air duct that runs through the superimposed Pipes are created, blown in. The compressed air blast can be more or less as required be strong and of more or less long duration.

4. The powdery bulk material (flour) is removed from the hopper via a screw printed into the sack via a round tube.

5. The worm flights are in the area of the sintered metal tube preferably narrowed so that the air-enriched bulk material is compressed and through the centrifugal force is pressed against the sintered metal. This will make the evacuation the air intensifies.
