Patentiert im Deutschen Reiche vom 28. Januar 1913 ab.Patented in the German Empire on January 28, 1913.
Die Erfindung bezieht sich auf ein Verfahren zum ununterbrochenen Brennen von Gips, wobei der grobgebrochene Gips, wie an sich bekannt ist, vor seiner weiteren Zerkleinerung vorgewärmt wird.The invention relates to a method for the continuous burning of Plaster of paris, the coarsely crushed plaster of paris, as is known per se, before its further crushing is preheated.
Gemäß der Erfindung wird der Gips der Vorwärmtrommel grobgebrochen zugeführt und passiert dann eine nach Art bekannter Trockentrommeln mit Mahlung und am AustrittsendeAccording to the invention, the plaster of paris is fed to the preheating drum and coarsely broken up then passes a type of known drying drum with grinding and at the outlet end
ίο mit Sortierung arbeitende Brenntrommel. Der Brand und die Vermahlung der Gipssteine finden somit gleichzeitig nebeneinander statt, wobei die voraufgehende Heizung und Trocknung bekanntlich den Stein weniger hart macht und die Vermahlung erleichtert.ίο burning drum working with sorting. Of the Firing and grinding of the gypsum stones thus take place side by side at the same time, the previous heating and drying is known to make the stone less hard and facilitates grinding.
Die Zeichnung zeigt eine Einrichtung zur Ausführung der Erfindung, und zwar in einem Längsschnitt (Fig. 1), einem Grundriß der geheizten Trommel (Fig. 2), und in dem Querschnitt nach Fig. 3.The drawing shows a device for carrying out the invention in one Longitudinal section (Fig. 1), a plan view of the heated drum (Fig. 2), and in the cross section according to Fig. 3.
Die Gipssteine, die durch ein Becherwerk 1 einem Trichter 2 zugehoben werden, fallen in die Vorwärmtrommel 3, in der sie entsprechend der Neigung und Drehung der Trommel um die Achse 4 vorrücken. Die Trommel 3 wird durch die sie umspülenden und teilweise durchströmenden heißen Gase, die den umgekehrten Weg verfolgen, erhitzt.The plaster stones, which are lifted to a funnel 2 by a bucket elevator 1, fall into the preheating drum 3, in which they advance according to the inclination and rotation of the drum about the axis 4. the Drum 3 is swept around it and partially flowing through the hot gases, those who follow the opposite path are heated.
Am Ende der Trommel 3 angelangt, fallen die Steine' in einen Trichter 5, und aus diesem in die geneigte Mahltrommel 6, in der sich der Brand vollzieht. Diese Trommel dreht sich um die Achse 7 und besteht aus zwei Teilen, von denen der erste, 6, mit voller Oberfläche zum Zermahlen der Steine dient, während der zweite, 6a, gelocht ist. Seine Lochung wird in der Richtung der Vorbewegung des Gutes größer. Die Trichter 8 befördern den feinen Gips in die Säcke 9, während die Trichter 8a den gröberen Gips in die Säcke ga bringen. Der Siebrückhalt wird am Ende durch den Trichter 10 ausgeworfen.Arrived at the end of the drum 3, the stones' fall into a funnel 5, and from there into the inclined grinding drum 6, in which the fire takes place. This drum rotates around the axis 7 and consists of two parts, of which the first, 6, with full surface is used to grind the stones, while the second, 6 a , is perforated. Its perforation becomes larger in the direction of the forward movement of the goods. The hopper 8 convey the fine gypsum into the bags 9, while the hopper 8 a coarser plaster in the sacks g a bring. The screen retainer is ejected through the funnel 10 at the end.
Die Mahltrommel 6 wird von außen auf ihrer ganzen Länge durch Brenner 11 (Fig. 2 und 3) geheizt, die insbesondere vorteilhaft mit vorgewärmtem Gas gespeist werden und deren Flammen wagerecht verlaufen und den unteren Teil der Trommel umspülen. 20 und 21 bezeichnen die Luft- und Gaszuführungsrohre. The grinding drum 6 is driven from the outside over its entire length by burner 11 (Fig. 2 and 3) heated, which are particularly advantageously fed with preheated gas and whose flames are horizontal and wash around the lower part of the drum. 20 and 21 denote the air and gas supply pipes.
Die Heizung kann auch durch Auspuffgase von Gasmotoren erfolgen.The heating can also be done by exhaust gases from gas engines.
Die Verbrennungsgase werden durch das Gewölbe 12 (Fig. 1) gezwungen, um den Trichter 5 herum in den oberen Kanal 30 zu strömen, wo ein Schirm 13 sie teilweise zwingt, die Trockentrommel 3 zu durchströmen, während sie dieselbe teilweise umspülen, ehe sie durch den Kamin 14 den Ofen verlassen.The combustion gases are forced through the vault 12 (Fig. 1) to the funnel 5 to flow around into the upper channel 30 where a screen 13 partially forces them to to flow through the drying drum 3 while they partially wash around the same before they leave the furnace through the chimney 14.
