Description
Der Erfinder hat beantragt, nicht genannt zu werden Verfahren zur Herstellung von Bauelementen aus Rohtorf und Trockenstoffen Die Erfindung betrifft ein Verfahren zur Herstellung von Bauielementen aus Rohtorf und Trokkenstoffen für tragende und nichttragende Konstruktionen, insbesondere von Bau- und Isolierplatten sowie von Isolierkörpern für die Wärme-, Kälte- und Elektrotechnik.The inventor has requested not to be named method for Manufacture of building elements from raw peat and dry matter The invention relates to a process for the production of building elements from raw peat and dry matter for load-bearing and non-load-bearing structures, in particular of building and insulating panels as well as insulating bodies for heating, cooling and electrical engineering.
Das Verfahren besteht gemäß der Erfindung im wesentlie'lien darin, daß grubenfeuchter Rohtorf als Grundstoff zunächst unter mechanischer Druckeinwirkung mindestens teilweise entwässert und anschließend in der natürlichen Struktur durch mechanische Zerkleinerung bis zurHomogenität verändert wird, worauf dem Grundstoff wenigstens, ein saugfähiger Trockenstoff zur Beseitigung des Kolloidwassers durch Koagulation sowie mindestens- ein geeigneter Katalysator zur Erschließung der das Kolloid@wasser bindenden Zellen beigesetzt werden und daß dem Mischgut vor dessen Verformung die Luft in einer Vakuumkammer entzogen wird.According to the invention, the method essentially consists in that pit-moist raw peat as a raw material initially under the action of mechanical pressure at least partially drained and then through in the natural structure mechanical crushing is changed to homogeneity, whereupon the base material at least one absorbent desiccant to remove the colloid water Coagulation as well as at least one suitable catalyst to develop the Colloid @ water-binding cells are buried and that the mixture before it Deformation the air is withdrawn in a vacuum chamber.
Weitere Merkmale der Erfindung ergeben sich aus den Ansprüchen und der Beschreibung, in welcher das erfindungsgemäße Verfahren an einem Beispiel gezeigt ist.Further features of the invention emerge from the claims and the description in which the method according to the invention is shown using an example is.
Der als Grundstoff für die Herstellung der Bauelemente dienende grubenfeudht,e, Rohtorf wird, vorzugsweise im Zuge seiner Gewinnung, unter inec'han.ischer Druckeinwirkung mindestens teilweise entwässert; so daß er beispielsweise noch einen Wassergehalt von 5o°/& oder weniger aufweist. Anschließend wird die natürlidhe Struktur des Torfes durch mechanische Zerkleinerung der Torffasern z. B. mit Hilfe eines Reißwolfes zerstört, worauf man das Gut in einer mit Messern versebenen Schneckenpresse vollendis homogenisiert. Zur Beseitigung des im Torf noch vorhandenen Kolloidwassers durch Koagulation wird,dem Grundstoff nachher gleichzeitig mit einem Katalysator wenigstens ein saugfähiger Trockenstoff von feiner Körnung beigemischt, wie Sägemehl, Diatomeenerde, Infusorienerde, trockener Torf, wobei diese Stoffe einzeln oder untereinander gemischt insgesamt bis zu 70 Volumprozent des Grundstoffes ausmachen können. Die Korngröße der Trockenstoffe beträgt zweckmäßigerwei@se weniger als 3 mm, wobei die Kornabstufung je nach oder gewünschten Festigkeit, der gewünschten Dichte und dem gewünschten spezifischen Gewicht der herzustellenden Bauelemente gewählt wird. Der Grundstoff und die Trockenstoffe werden mittels eines Doppelwellenmischers und einer Schneckenpresse unter Zusatz mindestens eines Katalysators innig miteinander gemischt, welcher Katalysator zur Erschließung der das Kolloidwasser bindenden Zellen des Grundstoffes dient.The raw peat used as the base material for the production of the structural elements is at least partially dewatered, preferably in the course of its extraction, under the influence of internal pressure; so that it still has a water content of 50% or less, for example. Subsequently, the natural structure of the peat by mechanical crushing of the peat fibers z. B. destroyed with the help of a shredder, whereupon the material is completely homogenized in a screw press that has been leveled with knives. To remove the colloid water still present in the peat by coagulation, at least one absorbent dry substance of fine grain size is added to the base material at the same time as a catalyst, such as sawdust, diatomaceous earth, infusor earth, dry peat, these substances mixed individually or with one another up to a total of 70 percent by volume of the raw material. The grain size of the dry matter is expediently less than 3 mm, the grain gradation being selected depending on the or desired strength, the desired density and the desired specific weight of the components to be produced. The base material and the dry matter are intimately mixed with one another by means of a twin-shaft mixer and a screw press with the addition of at least one catalyst, which catalyst serves to open up the cells of the base material that bind the colloid water.
Als Katalysator -hat sich ein Gemisch, dessen Hauptbestandteil gebrannter Kalk ist, als zweckmäßig erwiesen. Besonders gute Ergebnisse erzielt man durch Zusatz eines Katalysators der nachstehenden Zusammensetzung: Kalk-, Si-Stoff, Chlorkalk und Ammoniumphosphat, und zwar vorzugsweise in einer Menge von drei Volumprozent, wobei die prozentualen Anteile je nach Torf 30 bis 6o@% Kalk, 61,5 bis 3q.0/0 Si-Stoff, o,5 bis, q.'/0 Chlorkalk und 8 bis 2°/a Annmoniumphosphat betragen können.A mixture, the main component of which is quicklime, has proven to be useful as a catalyst. Particularly good results are achieved by adding a catalyst of the following composition: lime, silicon material, chlorinated lime and ammonium phosphate, preferably in an amount of three percent by volume, the percentages depending on the peat 30 to 60% lime, 61, 5 to 3q.
Das auf die beschriebene Weise erhaltene homogehe Gemisch wird nachher während mindestens 14 Tagen einem Maukprozeß unterworfen, welcher in Maukgruben durchgeführt wird, deren Temperatur nicht über -I- 18' C liegt, wonach die Aufbereitung des zu den Bauelementen verformbaren Materials beendigt ist.The homogeneous mixture obtained in the manner described is afterwards subjected to a mauling trial for at least 14 days, which took place in Maukgruben is carried out, the temperature of which is not above -I- 18 'C, after which the processing of the deformable material to the structural elements is finished.
Unmittelbar vor der Verformung wird dem aufbereiteten Material die Luft dadurch entzogen, daß es mit Hnlfe eines Schneckentriebes durch Siebe in eine Vakuumkammer gedrückt wird. Anschließend findet die Verformung je nach den herzustellenden Produkten in einer Strangpresse; einer Revolverpresse, einer 'hydraulischen oder pneumatischen Presse usw. statt, worauf die Formlinge inTrockenräumen bei Temperaturen bis zu -E- 30° C unter starker Luftumwälzung getrocknet werden.Immediately before the deformation, the processed material is the Air is withdrawn by the fact that it with the help of a worm drive through sieves into a Vacuum chamber is pressed. Then the deformation takes place depending on the one to be produced Products in an extruder; a turret press, a 'hydraulic or pneumatic press etc. instead, whereupon the briquettes in drying rooms at temperatures can be dried up to -E- 30 ° C with strong air circulation.
