Abstract
A system for removing matter from a filtering device includes a flow receiving device having a plurality of blocking portions. Each of the plurality of blocking portions is configured to substantially block a flow directed by a corresponding at least one of a plurality of filter passages of the filtering device. The system further includes a positioning assembly configured to assist in positioning the flow receiving device within the filtering device and relative to a filter media of the filtering device.
Claims34
A system for removing matter from a filtering device, comprising:
- a flow receiving device including a plurality of blocking portions and a plurality of channels, each of the plurality of blocking portions being configured to substantially block a flow directed by a corresponding at least one of a plurality of filter passages of the filtering device, each of the plurality of channels being configured to receive a flow directed by a corresponding blocked passage of the plurality of filter passages, and
- a positioning assembly configured to assist in positioning the flow receiving device within the filtering device and relative to a filter media of the filtering device.
A system for removing matter from a filtering device, comprising:
- a flow receiving device disposed proximate an outlet end of the filtering device and having a plurality of channels, each of the plurality of channels being configured to receive a flow from a corresponding one of a plurality of filter passages of the filtering device, each corresponding one of the plurality of filter passages being substantially blocked at a front face of a filter media of the filtering device;
- and
- a positioning assembly configured to assist in adjustably positioning the plurality of channels of the flow receiving device relative to the filter media.
A method of removing material from a filtering device, comprising:
- providing a flow receiving device including a plurality of blocking portions;
- adjusting the position of the plurality of blocking portions of the flow receiving device within the filtering device such that each of the plurality of blocking portions substantially blocks a flow directed by a corresponding at least one of a plurality of filter passages of the filtering device;
- and
- manipulating the flow receiving device such that each of the corresponding at least one filter passages is unblocked.
An engine exhaust filter system comprising:
- a filter including a plurality of elongated filter passages, wherein each filter passage includes an outlet end and an unblocked inlet end and is configured to permit gas to flow through a filter passage wall;
- a plurality of blocking portions having a first position in which each of the blocking portions is inserted into the outlet end of a corresponding filter passage to substantially block gas through the outlet end of each corresponding filter passage, the plurality of blocking portions have a second position in which each of the blocking portions is detached from the outlet end to permit gas flow through the outlet end of each corresponding filter passage, wherein the plurality of blocking portions are movable between the first position and the second position;
- and
- a positioning assembly configured to assist in positioning each of the plurality of blocking portions in the first position.
