, . 'Zusatz zum Patent 302641.,. 'Addendum to patent 302641.

Patentiert im Deutschen Reiche vom 16. Dezember 1916 ab. Längste Dauer: 7.Februar 1931.Patented in the German Empire on December 16, 1916. Longest duration: February 7, 1931.

Beim Lösen von Schlamm absetzenden Stoffen· in der chemischen Großindustrie nach dem Verfahren gemäß Patent 302641 hat sich herausgestellt, daß bei der entsprechenden nötigen Anwärmung viel feiner Schlamm, den man in der Lösung nicht zu haben wünscht, mitgetragen wird.When dissolving sludge-settling substances · in large-scale chemical industry the method according to patent 302641 has been found that in the corresponding necessary warming up a lot of fine sludge, which one does not wish to have in the solution, is carried.

Die nächstehend beschriebene Erfindung hilft diesem Übelstande ab, indem dafür gesorgt wird, daß durch Querschnittsvergrößerung des die Löseflüssigkeit aufnehmenden Behälters an der Ablaufstelle der Lösung eine Verringerung der Auftriebgeschwindigkeit erreicht wird; dabei, geschieht das Austreten der Lösung nicht mehr an einer Stelle, sondern der ganze Umfang dieser Erweiterung wird, als umlaufende Rinne ausgebildet, benutzt.The invention described below remedies this drawback by taking care of it is that by increasing the cross-section of the container receiving the dissolving liquid a reduction in the buoyancy velocity is achieved at the point where the solution runs off; in the process, the solution no longer emerges in one place, but rather the whole The extent of this extension is used as a circumferential channel.

Es ist klar, daß durch die Vergrößerung des Querschnitts die hier aufsteigende Lösung im Verhältnis zu der Querschnittsvergrößerung eine geringere Geschwindigkeit annehmen wird.It is clear that by enlarging it of the cross-section, the solution ascending here assume a lower speed in relation to the cross-sectional enlargement will.

Da nun die Lösung von dem kleineren Querschnitt zum großen in horizontaler Richtung radial nach dem ringförmigen Ablaufkanal sich bewegt, so kann während dieser horizontalen Wanderung der Schlamm, der bei: der ,Auftriebgeschwindigkeit des kleinen Querschnitts noch getragen wurde, bei der verringerten des größeren Querschnitts absinken. Now there is the solution from the smaller cross-section to the large one in the horizontal direction moves radially after the annular drainage channel, so can during this horizontal migration of the mud, which at: the, buoyancy speed of the small Cross-section was still worn, with the reduced of the larger cross-section sinking.

Um nun diesen Schlamm nicht wieder in die durch die Wärme der Dampfschlangen erzeugte Auftriebszone gelangen zu lassen, ist die Schlange innerhalb eines Eisenblechmantels verlegt, so daß zwischen Außenmantel und dem vorher erwähnten Blechmantel ein entsprechend weiter Zwischenraum entsteht.So as not to get this mud back into the heat of the steam coils The snake inside a sheet-iron jacket is to allow the upwelling zone created to reach it laid so that a correspondingly wider space is created between the outer jacket and the aforementioned sheet metal jacket.

Da der äußere Mantel des Apparates naturgemäß kälter ist als der, nach innen liegende Dampfschlangentragmantel; so ist ein Absinken des Schlammes an dieser Stelle gesichert. ;;i ■Since the outer jacket of the device is naturally colder than the one on the inside Steam coil support jacket; this ensures that the sludge will sink at this point. ;; i ■

Der nach unten sinkende Schlamm wird mit dem aus den Lösezylindern entfallenden Rückstand zusammen durch die Schnecke nach außen entfernt.The sludge that sinks down is combined with that from the release cylinders Residue is removed together by the auger to the outside.

Der Mantel des Apparates A bekommt in seinem oberen Teile A1 die rings umlaufende Erweiterung y mit der rings umlaufenden 5" Rinne z. Diese umlaufende Rinne hat zwei Ablaufstutzen w und einige Reinigungsdeckel q, um eventuelle Ablagerung entfernen zu können.The jacket of the apparatus A has in its upper part A 1 the all-round extension y with the all-round 5 "channel z. This all-round channel has two drainage nozzles w and some cleaning covers q to be able to remove any deposits.

Die im Innern des Apparates untergebrachten Heizschlangen s sind an einem geschlossenen Eisenblechmantel u befestigt, und dieser ist an mehreren Flacheisen % aufgehängt. Die Lösung steigt innerhalb dieses Schlangen-Systems auf und wandert oben nach der Abläufrinne radial hin, während der Schlamm zwischen Äußenmantel des Apparates A und Schlangenmantel u absinkt.The heating coils s housed inside the apparatus are attached to a closed sheet iron jacket u , and this is suspended from several flat irons%. The solution rises within this snake system and migrates radially at the top to the drainage channel, while the sludge sinks between the outer jacket of the apparatus A and the snake jacket u.
