Support structure for fluid treatment systems having belted filtration systems
The present technology is directed generally to fluid treatment systems. In particular, several embodiments are directed toward filter supports configured to be positioned adjacent a filter belt within a filter belt filtration system. In one embodiment, the filter support can have a longitudinal axis generally parallel to the direction of movement of the filter belt. The filter support can include a plurality of struts spaced apart by a plurality of openings, and at least one of the plurality of struts extends across a portion of the filter support such that a longitudinal axis of the at least one strut is positioned at an angle with respect to the longitudinal axis of the filter support.
1. A device comprising:
a filter support configured to be positioned adjacent a filter belt within a filter belt filtration system, the filter support having a longitudinal axis generally parallel to the direction of movement of the filter belt, wherein the filter support includes:
a first plurality of struts spaced apart by a plurality of first spacings, wherein the first plurality of struts extend across a first portion of the support such that longitudinal axes of the first plurality of struts are positioned at an angle of at least 10 degrees with respect to the longitudinal axis of the filter support;
a second plurality of struts spaced apart by a plurality of second spacings, wherein the second plurality of struts extend across a second portion of the support such that the longitudinal axes of the second plurality of struts are positioned at an angle of at least 10 degrees with respect to the longitudinal axis of the filter support; and,
wherein the first plurality of struts include struts on a first side of a centerline of the support that extend from a first edge on the first side to the centerline and shorter struts on a second side of the centerline opposite the first side that extend only between struts of the second plurality of struts,
wherein the second plurality of struts include struts on the second side that extend from the second edge to the centerline and shorter struts on the first side that extend only between struts of the first plurality of struts, and
wherein the filter support is made of a single sheet of material, the openings are cutouts in the sheet of material, and the struts are portions of the sheet of material.
2. The device of claim 1 wherein the filter support includes at least one longitudinal strut that runs parallel to the longitudinal axis of the filter support.
3. A treatment system, comprising:
a chamber configured to receive a fluid;
a cartridge positioned within the chamber, wherein the cartridge includes:
a frame;
a set of rollers;
a filter belt positioned around and between the rollers;
a filter support positioned on the frame, the filter support comprising:
a first plurality of struts spaced apart by a plurality of first spacings, wherein the first plurality of struts extend across a first portion of the support such that longitudinal axes of the first plurality of struts are positioned at an angle of at least 10 degrees with respect to the longitudinal axis of the filter support;
a second plurality of struts spaced apart by a plurality of second spacings, wherein the second plurality of struts extend across a second portion of the support such that the longitudinal axes of the second plurality of struts are positioned at an angle of at least 10 degrees with respect to the longitudinal axis of the filter support; and,
wherein the first plurality of struts include struts on a first side of a centerline of the support that extend from a first edge on the first side to the centerline and shorter struts on a second side of the centerline opposite the first side that extend only between struts of the second plurality of struts,
wherein the second plurality of struts include struts on the second side that extend from the second edge to the centerline and shorter struts on the first side that extend only between struts of the first plurality of struts, and
wherein the filter support is made of a single sheet of material, the openings are cutouts in the sheet of material, and the struts are portions of the sheet of material.
4. The system of claim 3 wherein the filter support includes at least one longitudinal strut that runs parallel to the longitudinal axis of the filter support.
5. The system of claim 3 wherein at least one of the plurality of first struts and the plurality of second struts are arranged in a chevron configuration.
