Description
Verfahren zur Herstellung von schüttbaren, als Filtermaterial dienenden Körpern Die Erfindung betrifft ein Verfahren zur Herstellung von aus festen Körpern bestehendem, schüttbarem Filtermaterial, das für die Reinigung von Wasser verwendet wird.Process for the production of pourable, used as filter material Bodies The invention relates to a method for producing solid bodies existing, pourable filter material that is used for purifying water will.
Es ist bekannt, Flüssigkeiten dadurch zu reinigen, daß diese durch in Filteranlagen aufgeschüttetes Filtermaterial, z. B. Kies oder Sand, geleitet werden. It is known to clean liquids by having them through Filter material heaped up in filter systems, e.g. B. gravel or sand, passed will.
Die in den Flüssigkeiten enthaltenen Schweb- und Sinkstoffe setzen sich dabei auf der Oberfläche der einzelnen Filterkörperchen ab und überziehen sie in Form einer feinen Haut. Die derart gebildeten sogenannten Filterhäute bewirken die Feinstreinigung der Flüssigkeiten.The suspended and suspended matter contained in the liquids settle are deposited on the surface of the individual filter bodies and cover them in the form of a fine skin. The so-called filter skins formed in this way cause the fine cleaning of liquids.
Es hat sich nun gezeigt, daß die Wirksamkeit der Kiesfilterkörper wesentlich erhöht werden kann, wenn die Oberfläche der die Filtermasse bildenden Kies körperchen vergrößert wird. Zu diesem Zweck werden erfindungsgemäß die Iiieskörperchen einer zur Erzeugung von klebrigen Überzügen dienenden Behandlung unterworfen und dann zwecks Vergrößerung ihrer Oberfläche mit festen Teilchen kleinerer Körnung, z. B; mit Sand oder granulierten Kunststoffkörnchen, bestückt. It has now been shown that the effectiveness of the gravel filter body can be increased significantly if the surface of the filter material forming Gravel corpuscle is enlarged. According to the invention, the milk bodies are used for this purpose subjected to a treatment serving to produce tacky coatings and then for the purpose of enlarging their surface with solid particles of smaller grain size, z. B; with sand or granulated plastic granules.
Zur Durchführung des erfindungsgemäßen Ver fahrens werden die Kieskörner vorzugsweise mit einem Azeton- oder ähnlichen Lack hauchdünn besprüht und dann z. B. mit entsprechend klassierten Sandkörnchen bestreut, so daß letztere auf der klebrigen Oberfläche der Kieskörner festhaften und nach dem Trocknen des Bindemittels nicht mehr davon entfernt werden können. Durch die derart vergrößerte Oberfläche der Kieskörner wird das Anhaften von Schwebstoffflöckchen auf ihnen erleichtert und das Aufnahmevermögen der Filtermasse für die aus der Flüssigkeit zu entfernenden Verunreinigungen ver größert. Dadurch wird auch die Laufzeit der Filter wesentlich verlängert. To carry out the process according to the invention, the gravel grains are preferably sprayed very thinly with an acetone or similar varnish and then z. B. sprinkled with appropriately classified grains of sand, so that the latter on the sticky Adhere to the surface of the gravel grains and not after the binder has dried more of it can be removed. Due to the increased surface of the gravel grains the adherence of suspended matter on them is facilitated and the absorption capacity the filter mass for the impurities to be removed from the liquid ver increases. This also significantly extends the running time of the filters.
Nach einem weiteren Merkmal der Erfindung können statt der Kieskörperchen kleine dünnwandige Kunststoffkörper benutzt werden, deren Oberfläche in gleicher Weise, wie oben angegeben, durch Teilchen kleinerer Körnung vergrößert wird. According to a further feature of the invention, instead of the gravel particles small thin-walled plastic body are used, their surface in the same Way, as stated above, is enlarged by particles of smaller grain size.
Einige Ausführungsbeispiele für die Kunststoffkörper, die sich zum Teil aus den Abfällen der Kunststoffindustrie ergeben, sind in der Zeidmung Abb. 1 bis 13 im Längs- und Querschnitt dargestellt. Some embodiments for the plastic body, which are to Part of the waste from the plastics industry is shown in Fig. 1 to 13 shown in longitudinal and cross-section.
Abb. 14 zeigt einen Körper mit aufgebrachten Körnern. So können diese Körper z. B. aus röhrchenförmigen Hohlkörpern von rundem, eckigem oder gewelltem Querschnitt oder aus flächigen Gebilden bestehen, die spiralig aufgewickelt, gewellt, gewinkelt, gelappt oder mit Zacken versehen sind. Vorteilhaft werden diese Körper gelocht oder perforiert.Fig. 14 shows a body with applied grains. So can this Body z. B. from tubular hollow bodies of round, angular or corrugated Cross-section or consist of flat structures that are spirally wound, corrugated, are angled, lobed, or serrated. These bodies become beneficial perforated or perforated.
PATENTANSPROCHE: 1. Verfahren zur Herstellung von schüttbaren, als Filtermaterial dienenden Körpern für die Wasserfiltration, dadurch gekennzeichnet, daß Kieskörner mit einem klebrigen Überzug versehen und dann zwecks Vergrößerung ihrer Oberfläche mit festen Teilchen kleinerer Körnung, z. B. mit Sand oder granulierten Kunststoffkörnchen, bestückt und anschließend getrocknet werden. PATENT CLAIMS: 1. Method of making pourable, as Filter material serving bodies for water filtration, characterized in that that gravel grains provided with a sticky coating and then for the purpose of enlargement their surface with solid particles of smaller grain size, e.g. B. with sand or granulated Plastic granules, loaded and then dried.
