DE202005009916U1 - Device for mechanical removal of algae from e.g. garden ponds etc. consists of driven rotating shaft with algae-collecting tip - Google Patents

Abstract

The device consists of a rotating shaft (1) with algae-collecting tip (3), and a drive mechanism (2). The tip has a non-rotary-symmetrical shape, and a rough surface with orientation towards the open end. The drive has a piston grip or a crank, or similar. It may be manual or electrical.

Description

Summary

The The invention relates to a mechanical device which facilitates the separation of filamentary Algae from waters, for example, from garden ponds, allowed.

The Device exists from one around the longitudinal axis rotating rod with an "algae catching" tip, either is not rotationally symmetric or a sufficiently high Has roughness.

By Rotational movements of the rod, the algae are fixed at the top and can be removed from the water.

State of Technology and its disadvantages

• – Chemische Mittel (Algizide) sind in der Regel sehr effektiv, haben jedoch verschiedene Nachteile: Zum einen führt die abgestorbene Algenmasse bei ihrem biologischen Abbau zu einer Senkung der Sauerstoff-Konzentration im Teich, was wiederum das Algenwachstum fördert. Einmal eingesetzt, müssen chemische Mittel im geschlossenen System Teich daher immer wieder zudosiert werden. Zum anderen können chemische Mittel negativen Einfluss auf höhere Organismen, z.B. Fische, haben.
• – Mechanische Filter in Verbindung mit einer Pumpe können effektiv Schwebstoffe abtrennen. Da Algenwachstum aber häufig an „ruhigen" Stellen des Teiches stattfindet, wo der Wasseraustausch klein ist, kann hier ein Filter wenig ausrichten.
• – Das mechanische Ablesen der Algen mittels eines Holzstabes, wie es bei Gartenteich-Besitzern in der Regel praktiziert wird, führt effektiv zu einer kompletten Entfernung der Algen, ist aber unpraktisch und zeitaufwendig.

Currently, there are a number of chemical and physical methods to reduce the algae stock of a pond:

• - Chemical agents (algicides) are usually very effective, but have several disadvantages: First, the dead algae mass in their biodegradation leads to a reduction in the oxygen concentration in the pond, which in turn promotes algae growth. Once used, chemical agents in the closed system pond must therefore be added again and again. On the other hand, chemical agents can have a negative impact on higher organisms, such as fish.
• - Mechanical filters in conjunction with a pump can effectively separate suspended matter. However, since algae growth often takes place in "quiet" areas of the pond, where the water exchange is small, a filter can do little here.
• - The mechanical reading of the algae by means of a wooden stick, as is usually practiced by garden pond owners, effectively leads to a complete removal of the algae, but is impractical and time consuming.

The The present invention simplifies the effective method of mechanical Reading off.

Innovation (s) by present Invention:

• – Einem um sich rotierenden Stab 1.
• – Einem Antrieb 2, der die Rotation des Stabes auslöst. Der Antrieb kann dabei manuell oder elektrisch erfolgen.
• – Einer algenfangenden Spitze 3 am unteren Ende des Stabes. Diese Spitze kann zum Beispiel eine asymmetrische Struktur („Zipfelmütze") oder eine andere, im Querschnitt nicht kreisförmige Struktur aufweisen. Des weiteren kann eine Spitze mit rauer Oberfläche verwendet werden, deren Struktur sowohl rotationssymmetrisch als auch nicht-rotationssymmetrisch sein kann.

In the present invention, a device is used which consists of at least the following individual parts:

• - A rod rotating around itself 1 ,
• - A drive 2 which triggers the rotation of the rod. The drive can be done manually or electrically.
• - An algae catching tip 3 at the bottom of the bar. This tip may, for example, have an asymmetric structure ("tip cap") or another non-circular cross-sectional structure, and may also use a rough-surfaced tine whose structure may be rotationally symmetric as well as non-rotationally symmetric.

Application examples:

Out a heavily occupied with filamentous algae, homogeneously overgrown pond were removed with different methods algae. For one thing became measured how much algae mass per unit of time could be removed. On the other hand, in a defined area, one was also determined Time algae removed and then the remaining remaining Algae mass weighed and thus determines the effectiveness. As a third test was determines in which time a certain water surface is Completely liberated from algae.

It shows that those described in the present invention torsion bars across from the common ones Comparative Examples - the usual Wooden stick and the looped filter both in terms of effectiveness as well as regarding time expenditure have clear advantages.
