Description

Trockenvorrichtung für Sand Gegenstand der Erfindung ist eine Vorrichtung zum Trocknen von Sand. Bisher wurde Sand z. B. in Trommeln mit innerer oder äußerer Beheizung getrocknet. Andererseits sind Trockeneinrichtungen in der chemischen und Kaliindustrie benutzt worden, bei denen das Trockengut durch stehende Schachte mittels eines heißen Luftstromes getrocknet wurde.Drying device for sand The subject of the invention is a device for drying sand. So far, sand was z. B. in drums with inner or outer Heating dried. On the other hand, drying facilities are in the chemical and Potash industry has been used, in which the dry material through standing shafts by means of a hot air stream was dried.

Die Erfindung betrifft nun :eine Vorrichtung, in welcher der Sand ebenfalls in :einem stehenden Schacht durch heiße Preßluft getrocknet wird. Das Neue besteht darin, daß der zur Trocknung verwendete Schacht aus nicht eisenhaltigen Baustoffen hergestellt ist, um zu verhindern, daß der Sand bei der Trocknung durch Aufnahme von Eisen verunreinigt wird.The invention now relates to: a device in which the sand also in: a standing shaft is dried by hot compressed air. That What is new is that the shaft used for drying is made of non-ferrous Building materials is made to prevent the sand from drying through Absorption of iron is contaminated.

Bei dem Trockner gemäß der Erfindung wird der Schacht i durch ein stehendes Rohr gebildet, an dessen unterem Ende durch eine Eintragwalze a der zu trocknende Sand eingebracht wird, während durch ein Gebläse 3 oder einen Ventilator aus :einem Lufterhitzer q. die erhitzte Luft angesaugt und mit solcher Geschwindigkeit in das: stehende Rohr gedrückt wird, daß der eingetragene Sand von dem heißen Luftstrom fortgeführt und durch den Schacht gefördert wird. Bei dieser Förderung gibt der Sand seine Feuchtigkeit an die Luft ab, so daß eine Trocknung bis auf o,oi % Wasserinhalt stattfindet. Um zu verhindern, daß die Prallfläche S, gegen welche der Luftstrom den Sand in den S.cheider 6 .schleudert, in kurzer Zeit abgenutzt wird, wird dieselbe aus Holz hergestellt und von Zeit zu. Zeit erneuert, so daß Störungen wegen beschädigter Prallflächen nicht auftreten können. In verschiedenen Industrien wird Sand von bestimmter Zusammensetzung und bestimmten Eigenschaften verlangt, so. darf z. B. in manchem Glassand kein Eisen enthalten sein. Statt des Eisens wird daher als Baustoff Aluminium, glasiertes Steinzeug u. dgl. zur Anwendung gebracht.In the dryer according to the invention, the shaft i is through a standing tube formed, at its lower end by an entry roller a to drying sand is introduced while by a blower 3 or a fan from: an air heater q. the heated air sucked in and at such speed is pressed into the standing pipe that the sand carried in by the hot air stream is continued and promoted through the shaft. With this promotion, the Sand its moisture to the air, so that it dries to a water content of 0.08% takes place. To prevent the baffle S, against which the air flow the sand is thrown into the S. separator 6., is worn out in a short time, becomes the same made of wood and from time to time. Time renewed so that malfunctions due to damaged Impact surfaces cannot occur. In various industries, sand is made of certain Composition and certain properties required so. may z. B. in some Glass sand does not contain iron. Instead of iron, aluminum is used as a building material, glazed stoneware and the like.
