Ergänzungsblatt zur Patentschrift 287236. KLASSE 22h. 'GRUPPE 7.Supplementary sheet to patent specification 287236. CLASS 22 h. 'GROUP 7.

Auf Seite i, Spalte i, nach Zeile 18 ist .folgender Wortlaut einzuschalten:On page i, column i, after line 18, the following wording must be included:

Demgegenüber besteht die vorliegende Erfindung nun in einem Verfahren, den Steinkohlenteer in dünnflüssigem Zustand unter geringstem Kraftaufwand, in möglichst kurzer Zeit und auf einfache, wenig umständliche Weise derart zu behandeln, daß er seine Konsistenz im wesentlichen beibehält, daß er aber trotzdem klebrige, harzige Eigenschaften erhält, die ihn als Bindemittel insbesondere für die Herstellung von Teermakadam befähigen. In contrast, the present invention now consists in a method, the coal tar in a thin-bodied state with the least amount of effort, in the shortest possible time and in a simple, not very cumbersome way Way to treat in such a way that it essentially maintains its consistency, but that it does nevertheless it receives sticky, resinous properties which make it particularly suitable as a binder qualify for the manufacture of tar macadam.

Das Verfahren besteht im wesentlichen darin, daß man die Teermasse wiederholt in möglichst dünne, regenartige Strahlen zerteilt und diese durch einen Raum führt, durch welchen heiße Luft von Temperaturen bis zu 120 ° C hindurchgeleitet wird. Zweckmäßig verwendet man hierzu zwei oder mehrere, konzentrisch angeordnete, möglichst fein durchlöcherte Trommeln, mittels welcher man den Teer in einem geschlossenen Gehäuse zentrifugiert, durch welches die heiße Luft hindurchgeleitet wird.The process consists essentially in repeating the tar mass in as much as possible thin, rain-like rays and leads them through a space through which hot air at temperatures up to 120 ° C is passed through. It is advisable to use two or more concentrically for this purpose arranged drums with holes as finely as possible, by means of which the tar can be removed centrifuged in a closed housing through which the hot air is passed will.

Würde man den Teer in Gefäßen auf Temperaturen über ioo° erhitzen, so würde hierbei einesteils ein starkes Aufschäumen und dadurch bedingte Brandgefahr eintreten, welchen Nachteilen durch Umrühren nur teilweise begegnet werden könnte, andernteils aber würde man auch bei langandauernder Behandlung nicht jenes Produkt erreichen, Welches man beim vorliegenden Verfahren unter dem Einfluß des Luftsauerstoffes auf den mechanisch fein verteilten Teer erhält.If one were to heat the tar in vessels to temperatures above 100 °, this would result in on the one hand there is strong foaming and the resulting fire hazard, which Disadvantages could only partially be countered by stirring, but on the other hand one would also be able to do so with longer duration Treatment does not achieve the product, which one in the present process obtained under the influence of atmospheric oxygen on the mechanically finely divided tar.

Claims

Have diameters like the largest drum 14 and with little play at the ends connect. In the limited by the approach 19 space opens the intake manifold on the Housing 7 arranged fan 20, that of ■ the also arranged on the housing 7 Motor 21 is put into action. Partly on the housing 7 and partly A container 22 is mounted on the heating device 1 and is used to hold to processing coal tar is used. From the container 22 a line 23 leads to a the shaft 11 lengthwise penetrating tube 24, which at the free end by a removable pin 25 is closed. The tube 24 has the length of the inside of the Drums 14 located part on the bottom six holes. The same length is also the shaft 11 with six rows of six holes each. In the line 23 is a housing 26, which is a removable Sieve contains, switched on. The bevel gear 13 or the shaft 11 can start from the bevel gear 27 be rotated while this receives its drive from the motor 21.

The rack frame located above the front walls can be boarded up and then used to hold heating material.
The use of the machine described is as follows:

The container 22 is filled with coal tar and the heating device is put into operation. The openings 6 and 9 remain in the boiler room 4 until the necessary heat is reached (about 120 °) closed. The tar, which by the heat of the underneath the container 22 located boiler room 4 is obtained in liquid form, flows through line 23 to pipe 24, any impurities contained in it through the sieve located in the housing 26 be held back. The sieve should be cleaned from time to time. The tube 24 is last completely filled with tar, which then flows through the holes of the same into the hollow shaft 11 arrives and also partially fills the latter. Will shaft 11 and with it the drums 14 set in rotation from the motor 21 by means of the angular gear 13, 27 (with 150 to 200 tours per minute), the tar located in the cavity of the shaft 11 becomes gradually thrown out through their holes, gets into the innermost drum 14, through their holes into the drum surrounding them, etc., until the tar bitumen that was obtained last is thrown out of the outermost drum 14 into the space of the housing 7, where it collects at its bottom and can be drained at 28. As soon as the wave 11 is set in rotation with the drums 14, the slides 5 and 10 are opened, so that, since the fan 20 also begins to work at the same time, a strong draft of air through the opening 6, the heating space 4 and the opening 9 after the housing 7, as a result, the hot air from the heating room 4 through the interstices of the drums 24 is sucked through. The hot air acts intensively on the tar, which is finely distributed by the drums 14, whereby the ammonia water contained in it evaporates completely and that in the tar contained oils are intimately mixed with its pitch content. The ammonia fumes will be sucked off by the fan and led into the open air.

Should the tar in the pipe 24 thicken with a temporary interruption of the process and plug its holes, the pin 25 can be removed and pushed in by a hot rod in the tube 24 of the tar in it are softened.

Instead of being mobile, the machine could also be made stationary.
