Abstract

A device for comminuting small ice bodies includes a housing without top and bottom walls in which a horizontally extending shaft is rotatably mounted. Disks forming beater knives are mounted on the shaft and counterknives in the form of cross-shaped breaking members are attached to the housing. Groups of adjacent disks define chambers in such a way that each chamber receives exactly one ice body. The chambers are arranged distributed over the circumference of the disks and along the length of the shaft in such a way that only a single ice body is comminuted at a given time. This reduces the power required for driving the shaft to a minimum.

Description

Die Erfindung betrifft eine Vorrichtung zum Zerkleinern von Kleineiskörpern, bestehend aus einem Gehäuse ohne Boden und Deckel, in dem eine Welle horizontal und drehbar gelagert ist, wobei an der Welle Schlagmesser, an dem Gehäuse Gegenmesser befestigt sind und Schlagmesser und Gegenmesser einen gegenseitigen Abstand, dem gewünschten Zerkleinerungsgrad entsprechend, besitzen.The invention relates to a device for crushing small ice bodies, consisting of a housing without a bottom and cover, in which a shaft is mounted horizontally and rotatably, with knives on the shaft, counter knives attached to the housing and knives and counter knives a mutual distance, the have the desired degree of comminution.

Derartige Eiszerkleinerer sind beispielsweise bekannt aus den DE-AS'en 19 44 142, 21 08 031 oder dem DE-GM 69 21 181. Diese besitzen eine angetriebene Welle, auf der nebeneinander eine Anzahl von Messern befestigt ist. Zwischen den Messern sind feste Gegenmesser angeordnet. Messer und Gegenmesser sind als Sichelmesser mit einer Mehrzahl von Spitzen ausgeführt, um die Eiskörper zu zerhacken.Ice crushers of this type are known, for example, from DE-AS 19 44 142, 21 08 031 or DE-GM 69 21 181. These have a driven shaft on which a number of knives are fastened next to one another. Fixed counter knives are arranged between the knives. Knives and counter knives are designed as sickle knives with a plurality of tips to chop the ice bodies.

Nachteilig bei den bekannten Vorrichtungen ist die Notwendigkeit, einen relativ starken Antrieb für die Zerkleinerungsvorrichtung vorsehen zu müssen, da die Zahl der zwischen Messer und Gegenmesser zerhackten Eiskörper völlig unkontrollierbar ist. Aus dem gleichen Grund ist die Körnung des zerkleinerten Eises auch sehr unregelmäßig. Mechanik und Antriebsleistung der bekannten Vorrichtungen müssen auf Belastungen ausgelegt werden, die in der Praxis nur selten erreicht werden.A disadvantage of the known devices is the need to provide a relatively strong drive for the comminution device, since the number of ice bodies chopped between the knife and counter knife is completely uncontrollable. For the same reason, the size of the crushed ice is also very irregular. The mechanics and drive power of the known devices must be designed for loads that are rarely achieved in practice.

Soweit bei den bekannten Vorrichtungen die zu zerkleinernden Eiskörper von der Seite zugeführt werden, sind auch nur kurze Baulängen für die Zerkleinerungsvorrichtung und damit auch nur eine geringe Zerkleinerungskapazität möglich.Insofar as the ice bodies to be shredded are fed from the side in the known devices, only short overall lengths for the shredding device and thus only a small shredding capacity are possible.

Neben den beschriebenen Zerkleinerungsvorrichtungen sind Maschinen bekannt, mit denen direkt Eisschnee hergestellt wird. Eine handelsübliche Vorrichtung verwendet eine Schnecke, die in einem senkrecht stehenden Rohr rotiert. Das Rohr ist tiefgekühlt und wird ständig mit Wasser besprüht, so daß fortwährend eine Eisschicht entsteht. Diese Eisschicht wird mit Hilfe der Schnecke abgeschabt. Der dabei entstehende Eisschnee wird mit Hilfe der Schnecke zu einer Abgabevorrichtung gefördert. Das so hergestellte Produkt ist ein trüber Eisschnee, der vom Verbraucher in vielen Fällen nicht akzeptiert wird.In addition to the crushing devices described, machines are known with which ice snow is produced directly. A commercially available device uses one Snail rotating in a vertical tube. The tube is deep-frozen and is constantly sprayed with water, so that an ice layer is constantly formed. This layer of ice is scraped off with the help of the screw. The resulting ice snow is conveyed to a delivery device with the help of the screw. The product produced in this way is cloudy ice snow, which in many cases is not accepted by the consumer.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art anzugeben, die mit kleinsten Abmessungen und minimalem Kraftbedarf die Zerkleinerung von Eiskörpern mit definierter Körnung ermöglicht und gleichzeitig auf praktisch beliebige Kapazität erweitert werden kann.The present invention has for its object to provide a device of the type mentioned, which allows the crushing of ice bodies with a defined grain size with the smallest dimensions and minimum power and at the same time can be expanded to practically any capacity.

Diese Aufgabe wird dadurch gelöst, daß auf der Welle eine Anzahl von Metallscheiben befestigt ist und daß aus einer Gruppe von benachbarten Scheiben Segmente derart herausgeschnitten sind, daß eine Kammer zur Aufnahme genau eines Eiskörpers entsteht.This object is achieved in that a number of metal disks are attached to the shaft and that segments are cut out from a group of adjacent disks in such a way that a chamber for receiving exactly one ice body is created.

Bei der erfindungsgemäßen Vorrichtung werden also die einzelnen Eiskörper in den Kammern, die durch segmentartige Ausschnitte aus den Metallscheiben gebildet sind, definiert gehalten, geführt und an den festen Gegenmessern zerkleinert. Dadurch ergeben sich die Vorteile, daß die Körnung sehr gleichmäßig ist, und der Kraftbedarf minimal wird, da die Zerkleinerung unter definierten Verhältnissen erfolgt. Außerdem sind die Bruchstücke klar, wenn die Eiskörper selbst klar waren.In the device according to the invention, the individual ice bodies in the chambers, which are formed by segment-like cutouts from the metal disks, are thus held, guided and comminuted on the fixed counter knives. This has the advantages that the grain size is very uniform and the power requirement is minimal, since the size reduction takes place under defined conditions. In addition, the fragments are clear if the ice bodies themselves were clear.

Gemäß einer vorteilhaften Weiterbildung sind am Scheibenumfang mehrere Kammern regelmäßig verteilt angeordnet. Ebenso ist es möglich, auch mehrere Kammern über die Länge der Welle verteilt anzuordnen. Hierdurch wird bereits die Zerkleinerungskapazität erhöht, ohne daß die Außenabmessungen verändert werden müssen.According to an advantageous development, a plurality of chambers are regularly distributed on the disk circumference. It is also possible to arrange several chambers distributed over the length of the shaft. This will the shredding capacity is already increased without having to change the outer dimensions.

Sind die Kammern gemäß einer bevorzugten Ausgestaltung der Erfindung derart verteilt angeordnet, daß zu jedem Zeitpunkt nur ein Eiskörper zerkleinert wird, kann die Antriebsleistung für die Messerwelle auf das absolute Minimum reduziert werden, ohne daß die Kapazität der Anlage darunter leidet.If, according to a preferred embodiment of the invention, the chambers are distributed such that only one ice body is crushed at a time, the drive power for the knife shaft can be reduced to the absolute minimum without the capacity of the system suffering as a result.

Vorzugsweise sind die Scheiben am Umfang profiliert. Dadurch werden die Eiskörper, die völlig unregelmäßig von oben in die Zerkleinerungsvorrichtung geschüttet werden, so ausgerichtet, daß sie lagerichtig in die Kammern einfallen. Dies gilt insbesondere dann, wenn die Eiskörper etwa Konus- oder Zylinderform besitzen.The disks are preferably profiled on the circumference. As a result, the ice bodies, which are poured into the comminution device from above in a completely irregular manner, are oriented such that they fall into the chambers in the correct position. This is especially true when the ice bodies are approximately conical or cylindrical in shape.

Gemäß einer Weiterbildung der Erfindung können zwischen den segmentierten Scheiben unsegmentierte Begrenzungsscheiben angeordnet sein. Durch Abdecken der Zwischenräume zweier Begrenzungsscheiben durch insbesondere dachförmige, gehäusefeste Abdeckungen ergibt sich eine verbesserte Zuführung der lose eingeschütteten Eiskörper zu den Zerkleinerungsstellen bzw. Kammern.According to a further development of the invention, unsegmented limiting disks can be arranged between the segmented disks. By covering the spaces between two boundary disks by means of roof-shaped covers fixed to the housing in particular, the loosely poured-in ice bodies are supplied to the crushing points or chambers in an improved manner.

Auch bei der erfindungsgemäßen Vorrichtung sind die Schlagmesser und die festen Gegenmesser scharfkantig und gezahnt, um die spröden Eiskörper leichter zerhacken zu können.In the device according to the invention, the striking knives and the fixed counter knives are sharp-edged and toothed in order to be able to chop the brittle ice bodies more easily.

Die festen Gegenmesser sind vorzugsweise als kreuzförmige Brechknochen ausgebildet, wodurch die Körnung noch gleichmäßiger wird. Außerdem kann auf diese Weise der Abstand zwischen den rotierenden Segmentscheiben größer gewählt werden als beim Stand der Technik.The fixed counter knives are preferably designed as cross-shaped crushing bones, which makes the grain even more uniform. In addition, the distance between the rotating segment disks can be chosen larger than in the prior art.

Anhand der Zeichnung soll die Erfindung in Form von zerhacken zu können.Based on the drawing, the invention in the form of to be able to chop.

Bei dem Ausführungsbeispiel der Fig. 2 sind auf der Welle 1 zusätzlich unsegmentierte Begrenzungsscheiben 8 angeordnet. Diese bilden sozusagen die Stirnwände der in den Segmentscheiben 2 gebildeten Kammern 3. Die Abstände zwischen zwei Begrenzungsscheiben 8 sind mit Hilfe von dachförmigen Abdeckungen 4 überbrückt, die in einfachster Weise auf Befestigungswinkeln 7 im Gehäuse 5 aufgesetzt werden können.In the embodiment of FIG. 2, unsegmented limiting disks 8 are additionally arranged on the shaft 1. These form the end walls of the chambers 3 formed in the segment disks 2, so to speak. The distances between two boundary disks 8 are bridged with the aid of roof-shaped covers 4, which can be placed in the simplest manner on fastening angles 7 in the housing 5.

In Fig. 3 schließlich erkennt man eine Anlage, die drei nebeneinanderliegende Zerkleinerungsabschnitte besitzt. Die Stirnseiten der Segmentscheiben 2 sind mit einer Profilierung 2.1 versehen, um die von oben eingeschütteten Eiskörper 9 so ausrichten zu können, daß sie in die Kammern 3 lagerichtig einfallen. Dies gilt insbesondere dann, wenn die Eiskörper etwa Konus- oder Zylinderform besitzen.3 finally shows a system which has three comminuting sections lying next to one another. The end faces of the segment disks 2 are provided with a profile 2.1 in order to be able to align the ice bodies 9 poured in from above so that they fall into the chambers 3 in the correct position. This is especially true when the ice bodies are approximately conical or cylindrical in shape.

An der Stirnwand des Gehäuses 5 sind zwischen den Segmentscheiben 2 die festen Gegenmesser zu erkennen, die vorzugsweise als kreuzförmige Brechknochen 6ʹ ausgebildet sind. Auf diese schlagen die Eiskörper auf und werden von den Segmentscheiben 2 bzw. deren scharfen Kanten 2.2 gebrochen.On the end wall of the housing 5, the fixed counter knives can be seen between the segment disks 2, which are preferably designed as cross-shaped breaking bones 6 '. The ice bodies hit them and are broken by the segment disks 2 or their sharp edges 2.2.

Da die die Eiskörper 9 aufnehmenden Kammern 3 sowohl am Umfang der Segmentscheiben 2 als auch über die Länge der Vorrichtung gegeneinander versetzt sind, und zwar so, daß vorzugsweise zu jedem Zeitpunkt nur ein Eiskörper zwischen Segmentscheiben 2 und Gegenmessern 6 zerkleinert wird, ist der (nicht dargestellte) Antrieb der Welle 1 lediglich auf den Kraftbedarf zur Zerkleinerung eines einzigen Eiswürfels auszulegen und ein Blockieren der Vorrichtung ausgeschlossen. Die definierte Lage der Eiskörper beim Zerkleinerungsvorgang untersützt zu dem ine gleichmäßige Körnung des Endproduktes.Since the chambers 3 receiving the ice bodies 9 are offset from one another both on the circumference of the segment disks 2 and over the length of the device, in such a way that preferably only one ice body is shredded between the segment disks 2 and counter knives 6, the (not shown) drive the shaft 1 only to the power required to crush a single ice cube and to prevent the device from blocking. The defined position of the ice bodies during the shredding process supports the even grain of the end product.

  • Fig. 2 shows a second embodiment of a crushing device for ice bodies in front view with the housing partially broken and
  • Fig. 3 shows a third embodiment of a crushing device for ice bodies in plan view.

Die Vorrichtung der Fig. 1 besteht aus einem etwa quaderförmigen Gehäuse 5 ohne Boden und Deckel, jedoch mit einer trichterartigen Einfüllvorrichtung 5ʹ am oberen Ende. Im Inneren des Gehäuses 5 ist eine Welle 1 waagerecht gelagert. Der Antrieb erfolgt über einen nicht dargestellten Motor.The device of FIG. 1 consists of an approximately cuboid housing 5 without bottom and lid, but with a funnel-like filling device 5 'at the upper end. A shaft 1 is mounted horizontally in the interior of the housing 5. The drive takes place via a motor, not shown.

Auf der Welle 1 sind in regelmäßigen Abständen Segmentscheiben 2 befestigt. Aus benachbarten Segementscheiben 2 sind Segmente 10 ausgespart, daß Kammern 3 entstehen, die auf die Größe der zu zerkleinernden Eiskörper 9 abgestimmt sind. Jede Kammer kann jeweils nur einen Eiskörper 9 aufnehmen.Segment disks 2 are attached to the shaft 1 at regular intervals. Segments 10 are cut out from adjacent segment disks 2 to create chambers 3 which are matched to the size of the ice body 9 to be shredded. Each chamber can only hold one ice body 9.

Im Ausführungsbeispiel der Fig. 1 sind mehrere Kammern 3 vorgesehen, die jedoch regelmäßig am Umfang der Welle 1 bzw. der Segmentscheiben 2 verteilt angeordnet sind, so daß die darin liegenden Eiskörper 9 zeitlich nacheinander den festen Gegenmessern 6 zugeführt und dort zerkleinert werden.In the embodiment of FIG. 1, several chambers 3 are provided, which, however, are regularly distributed around the circumference of the shaft 1 or the segment discs 2, so that the ice bodies 9 therein are successively fed to the fixed counter-knives 6 and comminuted there.

Die bei der Zerkleinerung aktiven Kanten 2.2 der Segmentscheiben 2 und der festen Gegenmesser 6 sind scharfkantig und gezahnt, um die Eiskörper 9 leichter können Gehäuse und Welle problemlos verlängert werden. Der Antrieb muß nur verstärkt werden, wenn die Verlängerung dazu führt, daß zur selben Zeit mehr als ein Eiskörper zwischen Messer und Gegenmesser zerkleinert wird.The edges 2.2 of the segmented disks 2 and the fixed counter-knives 6, which are active during comminution, are sharp-edged and toothed in order to make the ice bodies 9 lighter the housing and shaft can be easily extended. The drive only needs to be strengthened if the extension means that more than one ice body is shredded between the knife and counter knife at the same time.
