Abstract

The sieve drum washer cleans and separates mixtures of water and solids, and, in particular, rinses off filtration material comprising, e.g., sand or gravel which includes absorbed contaminants from potable water and service water purification. The drum is internally-sprayed and rotates about its horizontal axis, carried on rollers. It has a charging unit leading into it, and a rotary drive. New features include the charging device which reaches almost to the far, closed end of the drum. This is a channel (20), upwardly open over part of its length. On the inner wall of the sieve drum (7) there is a hollow spiral (8), conveying material over the washed sieve. Along the entire internal length of the drum, a row of downwardly directed spray-washing nozzles (23) is fitted. An enlarging collar (17) projecting out from the open end of the casing ejects the washed bulk material. Flanges (9, 10) at either end of the drum lie against axially-locating guide rollers (11, 12). Drive (5) is applied at the closed end of the drum, through a flexible coupling (6). A row of spray nozzles (27) located above the drum back wash the sieve perforations. Charging channel (20) and internal wash nozzle tube (24) are fastened to a traverse (25), which is detachable at the open end of the drum. The drum casing is made of curved, perforated- or slotted sheet, without reinforcements or bracing.

Description

Die Erfindung bezieht sich auf eine Trommelwasch- und -siebmaschine mit Innenbeaufschlagung nach dem Oberbegriff von Anspruch 1. Trommelwasch- und -siebmaschinen mit einer um eine Horinzontalachse angetriebenen drehbaren Siebtrommel sind üblicherweise im Durchlauf betrie­ ben und tauchen dafür mindestens bis über die Horizontalachse in das zu siebende Medium ein. Die mit ausgesiebten Schmutzstoffen belegte Innenseite der Siebtrommel wird oberhalb des Flüs­ sigkeitsspiegels durch, auf die Außenseite gerichteten Sprühdüsen, abgespült. Die abgespülten Siebübergänge werden in einer Ableitrinne aufgefangen. Mit der vorliegenden Erfindung soll eine andere Aufgabe gelöst werden. Es gibt in der Filtertechnik und in der Trink- und Brauchwasser­ aufbereitung Anwendungsfälle bei denen wäßrige Feststoffgemische getrennt, oder eine Feststoff­ suspension von Verunreinigungen gereinigt werden muß. Eine besonders häufig vorkommende Zweckbestimmung ist das Reinigen von Filtermaterial, wie Sand und Kies, aber auch Kunststoff­ granulat. In der Abwassertechnik sind Rechengutströme von der anhaftenden Organic, oder Schlachthofabfälle von den Feinsanden zu trennen. Bei Kartoffelschälabwässern muß die Stärke abgetrennt werden.The invention relates to a drum washing and screening machine with internal loading according to the preamble of claim 1. drum washing and screening machines with one by one The horizontal sieve drum, which is driven by the horizontal axis, is usually operated continuously To do this, immerse yourself in the medium to be screened at least up to the horizontal axis. The inside of the sieve drum covered with screened contaminants is above the river liquid level rinsed off by spray nozzles directed towards the outside. The rinsed off Sieve transitions are caught in a drainage channel. With the present invention one other task can be solved. There is in filter technology and in drinking and industrial water preparation applications where aqueous solid mixtures are separated, or a solid suspension must be cleaned of impurities. A particularly common one Purpose is to clean filter material such as sand and gravel, but also plastic granules. In wastewater technology, screenings flows are from the adhering organic, or Separate slaughterhouse waste from fine sands. In the case of potato peeling waste, the starch must be separated.

Für diese Wasch- bzw. Trennvorgänge gibt es noch keine geeignete Vorrichtung mit gutem Trenngrad. Diese Aufgabe wird nunmehr erfindungsgemäß durch die nach Anspruch 1 gekenn­ zeichnete Trommelwasch- und -siebmaschine gelöst. Hiermit wird eine Vorrichtung zur Verfü­ gung gestellt, die robust im Aufbau und preisgünstig in der Anschaffung und im Betrieb ist. Die an der Innenwand der Siebtrommel befestigte hohle Schneckenwendel sorgt für eine langsame Weiterförderung des Trennguts zum hintenliegenden Austrag. Während der Weiterförderung wird das Trenngut intensiv umgewälzt, die abzutrennende Feinfraktion wird abgerieben und durch das Spülwasser durch die Sieböffnungen ausgetragen. Die das Spülwasser aufbringenden Sprühdüsen können einen scharfen Strahl liefern, um das Abspülen der Feinfraktiven zu unterstützen. Sie kön­ nen aber auch als Fächerdüsen ausgebildet sein und bestreichen dann die ganze freie Oberfläche des umgewälzten Feststoffgemischs. Die sauberen und weitgehend wasserfreien Siebübergänge verlassen die Siebtrommel an dem der Einspeisung gegenüberliegendem offenen Stirnende. Für den leichten Austrag erhält die Siebtrommel hier einen konischen Kragen, der aus dem Gehäuse herausragt und die Siebübergänge in eine Auffang- oder Weiterverarbeitungsein­ richtung leitet.For these washing or separating processes, there is still no suitable device with a good one Degree of separation.

A device is hereby available Provided, which is robust in construction and inexpensive to buy and operate. The Hollow screw spiral attached to the inner wall of the sieve drum ensures a slow Further conveyance of the separated material to the discharge behind. During further funding the material to be separated is circulated intensively, the fine fraction to be separated is rubbed off and by the Rinsing water discharged through the sieve openings. The spray nozzles that apply the rinsing water can deliver a sharp jet to help wash off the fine fractions. You can NEN can also be designed as fan nozzles and then coat the entire free surface of the circulated solid mixture. The clean and largely water-free screen transitions leave the screening drum at the open one opposite the infeed  Forehead. For easy discharge, the sieve drum is given a conical collar protrudes from the housing and the screen transitions into a collecting or further processing direction.

Der einfache und robuste Aufbau der Trommelwasch- und -siebmaschine ist durch zwei an den Enden der Siebtrommel außen befestigten Flanschringe, und einen an der geschlossenen Stirn­ seite über eine flexible Kupplung angreifenden Antrieb, gekennzeichnet.
