Abstract

Mixer for viscous materials such as bitumen and asphalt has a vertical shaft with a few blades at the bottom which move between stationary blades, protruding from the tank walls. The bottom blades have forward inclined scraper plates attached to their leading edge to keep the domes bottom clear. Power consumption is reduced and the mixing time can be decreased if the leading edge to which a scraper is attached is a radial line from the centre of the vertical shaft.

Description

Gegenschaufelmischwerk mit verbesserter Bodenschaufelwirkung, Counter-bucket mixer with improved bottom bucket effect,

Die Erfindung bezieht sich auf eine Vorrichtung zum Mischen von zähem Gut, insbesondere von bituminsen Werkstoffen wie Gußasphalt verschiedenster Zusammensetzungeri Es sind Mischeinrichtungen bekannt, die Einzelmerkmale meiner Erfindung aufweisen,aber im Aufbau so kompliziert sind, daß sie zumindest im Verwendungsbereich Gußasphalt nicht zum Einsatz kommen. Siehe US Patente vom 14. Oktober 1930- 1.778.049 und vom30. März 1943- 2.351251 sowie das CH Patent vom 30. April 1961- 12e 4-01 Nr. 353724.The invention relates to a device for mixing tough Good, especially from bituminous materials such as mastic asphalt of various compositions Mixing devices are known which have individual features of my invention, but are so complicated in structure that they are at least in the area of use mastic asphalt are not used. See U.S. patents dated October 14, 1930- 1,778,049 and dated October 30, 1930. March 1943- 2.351251 as well as the Swiss patent dated April 30, 1961- 12e 4-01 No. 353724.

DEr im Gußasphaltbereich bisher im In- und Ausland eingesetzte Wankscheibenmischer der Firma Wie bau - Rothenbergen hat ebenfalls erhebliche Mängel.The rotary disc mixer that has been used in the mastic asphalt area at home and abroad the company Wie bau - Rothenbergen also has significant shortcomings.

1. Keinehaufelnde Wirkung vom Boden an aufwärts, dadurch sind Ablagerungen in körnigem Mischgut möglich, 2. Die Wank scheibeb setzen sich in kürzester Zeit mit Mischgut zu und verlierenihre Mischwirkung.1. No heaving effect from the bottom upwards, so there are deposits possible in granular mix, 2. The Wank discs settle in a very short time with mix and lose their mixing effect.

3.Durch großen Mischgutansatz an der rotierenden Einrichtung weitgehende knetende Wirkung, die einen enormen Kraftbedarf im Antrieb zur Folge hat.3. Due to the large amount of mix on the rotating device, extensive kneading effect, which results in an enormous power requirement in the drive.

4. Betriebsausfälle infolge Msterialbruchs durch Überlastung,'lange Mischzeiten und unbefriedigende Mischergebnisse sind nicht selten.4. Business failures due to material breakage due to overloading, 'long Mixing times and unsatisfactory mixing results are not uncommon.

Meine Erfindung , als Gebrauchsmuster unter Nr. SO 1f- 7-22 7103450 12e 4-01 auf die Firma Fritz Müller K G Frechen eingetragen, hat schon wesentliche unter 1-4 genannten Mängel ausgeschaltet und ist bei der vorgenannten Firma inzwischen über 10 Jahre im Einsatz.My invention, as a utility model under No. SO 1f- 7-22 7103450 12e 4-01 registered to the company Fritz Müller K G Frechen, already has essential The defects mentioned under 1-4 have been switched off and are now with the aforementioned company in use for over 10 years.

Die Firma Fritz Müller hat mir die Weiterverfolgung zum Zwecke der Patenterteilung überlassen. ( Siehe Anlagen) Meiner Erfindung liegt die Aufgabe zugrunde, die Mischleisteing (Mischzeit) zu verbessern,und die Wirtschaftlichkeit durch weniger Kraftbedarfu und durch weniger Verschleiß erheblich günstiger zu gestalten.The Fritz Müller company gave me the follow-up for the purpose of Leave the patent to be granted. (See attachments) My invention is the task based on improving the mixing baring (mixing time) and economy to be made considerably cheaper due to less power consumption and less wear and tear.

L)iese Aufgabe wird erfindungsmäßig dadurch gelöst,daß'die schaufelnde Wirkung der Bodenschaufel über die an der Außenwanddes Behälters Crtsfest angebrachte Gegenschaufel,und einer weiteren rotierenden Schaufel im ZusammenspieMden gewünschten Erfolg bringt Die jetzt versetzt an der Rührwelle(Teil-3) angebrachten unteren Schaufeln(TeiS4) bringen folgende Vorteile :-1. Die Aufgreifstellung ist erheblich günstiger,dadurch wird das Mischgut nicht mehr an die Außenwand gepreßt.L) his object is achieved according to the invention that'die shoveling Effect of the bottom scoop via the Crts fixed on the outer wall of the container Counter vane, and another rotating vane in combination as desired Success brings the lower blades (part 4) now offset on the agitator shaft (part 3) bring the following advantages: -1. The take-up is considerably cheaper, because of that the mix is no longer pressed against the outer wall.

2.Die Vorderkanten der Bodenschaufeln (Teilrfi) kommen um 150mm näher an die Rührwellenachse(Teili), welches einen um 300mm verringeten Durchmesser des toten Mischbereiches zur Folge hat.2. The leading edges of the bottom shovels (Teilrfi) come 150mm closer to the agitator shaft axis (Teili), which has a diameter of the dead mixing area.

3. Neben einer verbesserten Mischleistung ist: auch eine Verringerüng vonKraftbedarf und Verschleiß die Folge.3. In addition to an improved mixing performance, there is also a reduction the result of power requirements and wear and tear.

Die nur noch wenigen Innenteile gegenber bisher bekannten Mischeinrichtungen bewirkenden geringen Kraftbedarf,die große Raumausnutzung für das Mischgut und den geringen Verschleiß. Die Befüllung des Mischers auch über den 8ereich der Schaufeln spielt keine Rolle,' da die wallende Wirkung der Schaufeln das Mischgut von oben bis unten erfaSt.Für anfallende Reparaturen im Mischer ist jetzt erheblich mehr Bewegungsfreiheit vorhanden.The only few internal parts compared to previously known mixing devices causing low power requirement, the large use of space for the mix and the low wear. The mixer can also be filled via the area of the blades does not matter, 'because the swaying effect of the shovels feeds the mix from above Recorded down to the bottom, there is now considerably more for repairs in the mixer Freedom of movement available.

Die mit de:t 2 lß 'erzielterb Verteilte sind: -erheblich geringere Baukosten.Deutliche Verringerung der Betriebskosten durch geringeren Kraftbedarf und kürzere Mischzeit, sowie einwandfreie Mischergebnisse.The one with de: t 2 lss 'achieved Distributed are: - Significantly lower construction costs. Significant reduction in operating costs due to lower power requirements and shorter mixing times, as well as perfect mixing results.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and is described in more detail below.

Es zeigen die Figur lund 2-u*4piç für den Nutzeffekt ausschlaggebende Schaufelnde Wirkung fördert das Mischgut Don TeiX6 über Teil 4, und wird durch die ortsfest an der Außenwand angebrachte Schaufeln und die rotierende Schaufeb4a weiter nach oben gebracht.It shows the figure 1 and 2-u * 4piç decisive for the efficiency Shoveling effect promotes the mix Don TeiX6 over part 4, and is made by the Fixed blades attached to the outer wall and the rotating Schaufeb4a further brought up.
