Description

Vorrichtung zur Entnahme von Proben aus sich bewegendem Schüttgut Die Erfindung betrifft eine Vorrichtung, mit der man aus sich bewegendem Schüttgut, das auf Schwingrinnen, Wuchtförderern, Drehtellern, Plattenbändern usw. befördert wird1 in beliebigen Zeitabständen kleine Mengen als Probe entnehmen kann Es sind Probenehmer bekannt, die das Material senkrecht zum Gutstrom, z.B. mit einem Schaber, oder in Laufrichtung, z.B. mit Hilfe eines kleinen Becherwerkes, von der Materialoberfläche entnehmen. Solche Probenehmer können entweder nur bei dem Fehlen einer seitlichen Begrenzung des Fördermittels arbeiten oder sind durch den nötigen mechanischen Aufwand kompliziert und störanfällig. Device for taking samples from moving bulk material The invention relates to a device with which one can move bulk material, that is conveyed on vibrating troughs, balancing conveyors, turntables, apron conveyors, etc. will1 can take small amounts as a sample at any time Sampler known, which the material perpendicular to the flow of material, e.g. with a scraper, or in the direction of travel, e.g. with the help of a small bucket elevator, from the material surface remove. Such samplers can either only in the absence of a lateral Limitation of the conveyance work or are due to the necessary mechanical effort complicated and prone to failure.

Die erfindungsgemäße Vorrichtung besteht aus einem Rohr, dosen lichte Weite der Korngröße des zu entnehmenden Materials angepaßt ists vorzugsweise dem 5 - 10-fachen des größten Kornes im Schüttgut entspricht. Das Rohr ist um eine Querachse schwenk- bzw. drehbar und kann mit Hilfe einer mechanischen Vorrichtung verschieden tief in den sich bewegenden gutstrom eingetaucht werden. Durch eine am Kopf dieses Rohrs befindliche, im allgemeinen seitliche Öffnung, die der Materialbewegung entgegengesetzt angeordnet ist, füllt sich der Kopf mit Material. Beim Herausheben des Rohr kopfes fließt die Probe durch das Innere des Rohre in ein Sammelgefäß. Der Arbeitstakt der Vorrichtung, d h. Eintauchen, Verweilen und Herausnehmen des hohes wird über einen Zeitgeber gesteuert der unabhängig oder mit anderen Vorgängen gekoppelt arbeiten kann.The device according to the invention consists of a tube, cans clear The width of the grain size of the material to be removed is preferably adapted to the 5 - 10 times the largest grain in the bulk material. The tube is around a transverse axis pivotable or rotatable and can be different with the help of a mechanical device be immersed deeply in the moving stream of good. By one at the head of this Tube located, generally lateral opening that opposes the movement of the material is arranged, the head fills with material. When lifting out the pipe head the sample flows through the inside of the tube Collection vessel. The working cycle of the device, i. Immerse, linger and remove the high is controlled by a timer that is independent or with other processes can work coupled.

In der Fig. ist eine Ausführungsform der Vorrichtung schematisch dargestellt.In the figure, an embodiment of the device is shown schematically.

Auf dem Fördermittel (1), z.B. einem Plattenband, wird das zu probende Material (2) transportiert. Der Probenehmer befindet sich in der Entnahmestellung (3). Er besteht aus dem Rohr (4), das um die Achse (5) drehbar gelagert ist.On the conveyor (1), e.g. an apron conveyor, the Material (2) transported. The sampler is in the removal position (3). It consists of the tube (4) which is rotatably mounted about the axis (5).

Der Entnahmekopf (6) mit der Entnahmeöffnung weist in die der Transportrichtung entgegengesetzte Richtung. Nachdem sich der Kopf mit der Probemenge gefüllt hat, wird er mit Hilfe des Preßluftzylinder (8), der über eine Stange am Punkt (7) angreift, in die Entleerungsstellung (3) gehoben.The removal head (6) with the removal opening points in the direction of transport opposite direction. After the head has filled with the sample, it is done with the help of the compressed air cylinder (8), which engages via a rod at point (7), lifted into the emptying position (3).

Das Material fällt in das Auffanggefäß (9) und bildet dort eine Sammelprobe (10). Der Vorgang wird in seinem zeitlichen Ablauf vom Schaltwerk (12) über die Magnetventile (11) gesteuert.The material falls into the collecting vessel (9) and forms a collective sample there (10). The process is timed by the switching mechanism (12) via the Solenoid valves (11) controlled.
