Embodiment Construction

[0035] The present invention will be described in more detail below by illustrating preferred embodiments of the invention with reference to the accompanying drawings.

[0036] The rotary disc filter device of the present invention includes a support structure 20, which rotatably supports a rotor 21 rotatable around a rotation axis Ax.

[0037]The supporting structure 20 includes a housing 22 with an inflow opening 23 arranged at one end of the housing 22 in the vicinity of the axis Ax. The inflow port 23 is connected to an inflow pipe 23 a extending through the central portion of the housing 22 . Inflow pipes 23 b are fixed at both ends of the housing 22 , which have openings 23 b arranged opposite to the inside of the disc-shaped filter element 30 . The interior of the disc-shaped filter element is defined by the space defined by its opposing walls. The outflow opening 24 is arranged on the opposite end side of the housing 22 near the bottom 25 of said housing 22 . A flus...

Abstract

A rotary disc filter device includes a rotor rotatable about an axis of rotation. The rotor includes a plurality of disc-shaped filter members, each disc-shaped filter member having a frame. The frame is made of sheet metal elements which are connected with each other by rivets.

Description

technical field [0001] The invention relates to a rotary disc filter device comprising a rotor rotatable about an axis of rotation, the rotor comprising a plurality of disc-shaped filter elements, each disc-shaped filter element having two slave rotating A wall that extends outward. Background technique [0002] Filtration devices, such as rotary disc filters, are primarily used to filter particles from liquids. [0003] A common rotating disc filter element is disclosed, for example, in SE-C-224131, the principle of which is represented in FIG. 1 . The rotary disc filter 1 comprises a rotor with a horizontal, slowly rotating drum 11 supporting a plurality of parallel, disc-shaped filter elements 12 arranged along the central axis of the drum 11 They are arranged at intervals in sequence and extend radially out of the drum (partially shown in Figure 1). On its parallel-oriented opposite side surfaces, the disc-shaped filter element 12 has openings which are covered with a...
