Stirring element and agitator

Abstract

The invention relates to a stirring element of a stirrer for mixing and/or homogenizing or suspending flowable media, which is substantially spherical in shape. The invention further relates to a stirrer having at least two stirring elements according to the invention.

Claims

1. A stirrer for mixing and/or homogenizing or suspending flowable media, comprising two or more stirring elements, characterized in each of the stirring elements is mounted to a driveable rotary shaft by a support arm and rotates together with the drivable rotary shaft, each of the stirring elements being spherically configured as a round body, and comprising a closed outer surface and being arranged at the same angular distance to one another and in a common radial plane further comprising a hub, each stirring element is connected to the hub via one of the support arms, the hub connecting the support arms to the drivable shaft.

2. Stirrer according to claim 1, characterized in that the outer surface of each the stirring elements has no edges or points.

3. Stirrer according to claim 1, characterized in that each of the stirring elements is a hollow body, preferably made of metal or plastic.

4. Stirrer according to claim 1, characterized in that the stirring elements are disposed symmetrically at the same distance to the drivable rotary shaft.

5. Stirrer according to claim 1, characterized in that the stirring elements have the same size and the same shape.

6. Stirrer according to claim 1, characterized in that the stirring elements are movable on a circular path around the drivable rotary shaft.

7. Stirrer for mixing and/or homogenizing flowable media, having three stirring elements according to claim 1, characterized in that the three stirring elements are fastened, spaced apart, to the drivable rotary shaft by the support arm.

Description

(1) A preferred embodiment of the invention is discussed in more detail in the following with the aid of the drawing. The drawing shows:

(2) FIG. 1 a perspective three-dimensional view of a stirrer according to the invention.

(3) The stirrer of FIG. 1 comprises three stirring elements 1 according to the invention, each of which is connected to a hub 2 via a support arm 3.

(4) In this design example, the stirring elements 1 are spherical. They are formed by spherical hollow bodies made of metal or plastic, each of which is attached to a radially outward end of a support arm 3.

(5) During operation, the hub 2 is coaxially connected to the not depicted rotary shaft of the stirrer for the purpose of joint rotation about the axis of rotation of the stirrer. Therefore, during operation, the stirrers move on a common circular trajectory around the rotary shaft.

(6) The invention is not restricted to the embodiment shown in FIG. 1. In particular the number of stirring elements 1 as well as their cross-sectional shape and their arrangement relative to one another can vary. The invention is furthermore not restricted to the dimensions selected in the drawing. The respective specific dimensions emerge as a function of the intended field of application and are in particular adapted to the size of a container accommodating the stirred material.
