Abstract

The apparatus consists of a cylinder with an inner wall (2) which is cooled from the outside and through which the aqueous solution is passed. An outer cylinder (7) coaxial with the inner one and two end walls form a chamber (4) which is filled with a coolant fluid or a cold brine, and ice crystals which form on the inner surface of the inner wall are removed by a scraper. The scraper is in the form of an Archimides screw (1) which has an outer diameter equivalent to the inner diameter of the cylinder. The temperature at which the ice crystals for depends on the freezing point of the coolant, which can contain e.g. culinary salt, ammonia ethanol.

Description

Die Erfindung betrifft eine Vorrichtung zum Erzeugen einer wäßrigen Suspension von kleinen Eiskristallgebil­ den, mit einem durch eine Wandung begrenzten zylindri­ schen Raum, durch den die wäßrige Suspension geführt wird, während die Wandung von außen gekühlt wird, und mit einer Einrichtung zum Abschaben der sich an der Innen­ seite der Wandung bildenden Eiskristalle.The invention relates to a device for generating an aqueous suspension of small ice crystals den, with a zylindri delimited by a wall the space through which the aqueous suspension is passed is while the wall is cooled from the outside, and with a facility for scraping off the inside side of the wall forming ice crystals.

Es ist vorteilhaft, zum Transport und zur Speicherung von Energie das Phänomen der Umwandlungswärme zu nutzen, also der Wärme, die bei Phasenübergängen verbraucht oder wieder freigesetzt wird, ohne zu einer entsprechenden nennenswerten Temperaturveränderung zu führen. It is advantageous for transportation and storage of energy to use the phenomenon of conversion heat ie the heat that is consumed during phase transitions or is released again without corresponding significant temperature change.  

Zu diesem Zweck werden Kältemaschinen der eingangs genannten Art verwendet, bei denen die sich an der Innenseite der Wandung bei Kühlung von deren Außenseite bildenden Eiskristalle über umlaufende Wischblätter ab­ gestreift werden.For this purpose, chillers are the beginning uses the type mentioned, in which the Inside of the wall when cooling from the outside forming ice crystals over wiper blades be touched.

Der Erfindung liegt die Aufgabe zugrunde, die vorbekann­ te Vorrichtung derart weiterzubilden, daß auf umlaufende Wischer verzichtet werden kann.The invention is based on the object that previously known te further develop such that on rotating Wipers can be dispensed with.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Einrichtung nach Art einer angetriebenen archimedi­ schen Schraube ausgebildet ist, deren Außendurchmesser dem Innendurchmesser des zylindrischen Raums im wesent­ lichen entspricht.According to the invention this object is achieved in that the establishment in the manner of a powered archimedi rule screw is formed, the outer diameter essentially the inside diameter of the cylindrical space corresponds.

Eine bevorzugte Ausführungsform zeichnet sich durch eine zweite, zu der ersten Wandung koaxial verlaufende Zylin­ derwandung aus, die mit dieser einen zylindrischen Man­ telraum bildet, der ein Kältemittelfluid aufnimmt. Dabei ist die koaxiale Ausbildung keineswegs zwingend, die beiden Wandungen können auch exzentrisch zueinander ver­ laufen.A preferred embodiment is characterized by a second cylinder, coaxial with the first wall derwandung with this one cylindrical man forms space that receives a refrigerant fluid. Here coaxial training is by no means compulsory both walls can also ver eccentrically to run.

Die Erfindung wird im folgenden anhand einer Zeichnung erläutert, in der die Vorrichtung in einer schematischen Querschnittsansicht dargestellt ist.The invention is described below with reference to a drawing explained in which the device in a schematic Cross-sectional view is shown.

Die Vorrichtung besteht aus einer ersten zylindrischen Wandung 2 und einer zweiten, zu dieser koaxial verlau­ fenden zweiten Zylinderwandung 7, wobei der durch die Wandungen 2, 7 gebildete Mantelraum 4 mit einem Kälte­ mittelfluid oder einer kalten Sole gefüllt ist. The device consists of a first cylindrical wall 2 and a second, to this coaxial duri fenden second cylinder wall 7 , wherein the jacket space 4 formed by the walls 2 , 7 is filled with a coolant medium fluid or a cold brine.

In dem durch die erste Wandung 2 gebildeten zylinderi­ schen Innenraum ist eine eine Förderschnecke bildende, angetriebene archimedische Schraube 1 angeordnet, deren Außendurchmesser dem Innendurchmesser des durch die Wan­ dung 2 begrenzten zylindrischen Raums im wesentlichen entspricht.In the space formed by the first wall 2 zylinderi's interior a forming a conveyor screw driven Archimedean screw 1 is arranged, whose outer diameter corresponds to the inner diameter of the extension by 2 Wan limited cylindrical space substantially.

Das Kältemittelfluid in dem Mantelraum 4 wird die Wan­ dung 2 derart abkühlen, daß die wäßrige Suspension oder Mischung, die in Richtung des Pfeiles 3 in den Innenraum eingeführt wird, soweit abgekühlt wird, daß sich an der Wandung 2 Eiskristallgebilde absetzen. Diese Eiskri­ stallgebilde werden nun bei Drehung der archimedischen Schraube 1 entweder durch unmittelbares Kratzen oder aber durch eine Strömungswirkung von der Wandung 2 abge­ löst und mit der Flüssigkeit in dem Innenraum vermischt. Dabei treibt die archimedische Schraube 1 die wäßrige Suspension der kleinen von der Wandung 2 abgelösten Eis­ kristallgebilde in der Zeichnung nach oben weiter und führt diese in Richtung des Pfeiles 6 aus dem Innenraum wieder aus.The refrigerant fluid in the shell chamber 4, the dung Wan cool down that the aqueous suspension or mixture, which is introduced in the direction of arrow 3 in the interior space is cooled to the extent that settle on the wall 2 Eiskristallgebilde 2 so. This Eiskri stallgebilde are now abge when the Archimedean screw 1 rotates either by direct scratching or by a flow effect from the wall 2 and mixed with the liquid in the interior. The Archimedean screw 1 drives the aqueous suspension of the small ice crystals detached from the wall 2 further upwards in the drawing and executes them again in the direction of arrow 6 from the interior.

Die in den Innenraum eingeführte Flüssigkeit besteht aus Wasser, dem vorzugsweise eine oder mehrere den Gefrier­ punkt erniedrigende Substanzen (beispielsweise Kochsalz, Ammoniak, Ethanol oder dergleichen) zugegeben ist. Die Art und die Menge der zugegebenen, den Gefrierpunkt er­ niedrigenden Substanzen beeinflussen die Temperatur, bei der die Bildung der sich an der Wandung 2 absetzenden Eiskristallgebilde einsetzt, wobei es wichtig ist, daß diese von der archimedischen Schraube 1 abgestreift wer­ den, bevor diese zu größeren Eisansammlungen zusammen­ frieren.The liquid introduced into the interior consists of water, to which one or more substances which lower the freezing point (for example sodium chloride, ammonia, ethanol or the like) are preferably added. The type and amount of added, the freezing point he lower substances influence the temperature at which the formation of the ice crystal structure settling on the wall 2 begins, it being important that these are stripped off by the Archimedean screw 1 , before the latter freeze larger ice accumulations together.
