Abstract
A filter bag for a rotary disk filter, which is used to filter wastewater, has a filter material with a mounting opening, via which the filter bag can be slipped over a support frame of the rotary disk filter during a mounting step in order to form a filter module. The filter material has an exit opening that is situated opposite the mounting opening and allows filtrate to exit the interior of the filter module into a central pipe of the rotary disk filter. A reinforcement is connected to the filter material at an edge delimiting the mounting opening and fixes the filter bag at the support frame. A filter module and a rotary disk filter are disclosed.
Claims9
A filter module for a rotary disk filter, which is configured to remove filtrate from wastewater, the filter module comprising:
- a support frame and a filter bag, which encloses at least a section of the support frame, wherein the filter bag includes:
- a filter material that defines a mounting end and an exit end spaced apart from and opposite the mounting end,
- wherein the filter material defines an interior between the mounting end and the exit end,
- wherein the filter material defines an edge that delimits a mounting opening at the mounting end of the filter material,
- wherein the mounting opening is configured to be slipped over a support frame of the plurality of filter modules to form a filter module,
- wherein the filter material defines an exit opening at the exit end of the filter material, wherein the exit opening is configured to allow the filtrate to exit the interior of the filter module into a central pipe of the rotary disk filter, and
- a reinforcement, which is connected to the filter material at the edge thereof, wherein the reinforcement is configured to fix the filter bag at the support frame,
- the filter module further comprising a clamping bar that is configured and disposed to exert a clamping effect and retains the filter bag pressed to the support frame at the mounting opening.
A rotary disk filter comprising:
- a central pipe extending along a longitudinal direction;
- a plurality of filter disks, which are arranged adjacent to one another in the longitudinal direction of the central pipe and connected to the central pipe, wherein each filter disk includes a plurality of filter modules, which are arranged adjacent to one another in the circumferential direction with respect to the longitudinal direction of the central pipe, wherein each of the plurality of the filter modules includes:
- a support frame and a filter bag, which encloses at least a section of the support frame, wherein the filter bag includes:
- a filter material that defines a mounting end and an exit end spaced apart from and opposite the mounting end,
- wherein the filter material defines an interior between the mounting end and the exit end,
- wherein the filter material defines an edge that delimits a mounting opening at the mounting end of the filter material,
- wherein the mounting opening is configured to be slipped over a support frame of the plurality of filter modules to form a filter module,
- wherein the filter material defines an exit opening at the exit end of the filter material, wherein the exit opening is configured to allow the filtrate to exit the interior of the filter module into the central pipe of the rotary disk filter, and
- a reinforcement, which is connected to the filter material at the edge thereof, wherein the reinforcement is configured to fix the filter bag at the support frame.
