Abstract
A system for removing particulates from a filtering device of a machine. The system may include a flow assembly configured to direct a flow of gas through the filtering device, with one or more elements of the flow assembly being removably attached to a first opening of the filtering device. The system may also include a sound generation assembly configured to direct sound waves toward the filtering device to remove particulates from the filtering device.
Claims19
A system for removing particulates from a filtering device of a machine, comprising:
- an engine in flow communication with the filtering device;
- a first valve located between the engine and the filtering device, the first valve configured to permit a flow of exhaust from the engine into the filtering device when the first valve is in a first position and the first valve configured to block the flow of exhaust into the filtering device when the first valve is in a second position;
- a flow assembly configured to direct a flow of gas through the filtering device when the first valve is in the second position, one or more elements of the flow assembly being removably attached to a first opening of the filtering device;
- and
- a sound generation assembly configured to direct sound waves toward the filtering device to remove particulates from the filtering device.
A method of removing particulates from a filtering device of a machine, comprising:
- removably attaching a service system to a first opening of the filtering device;
- blocking a flow of exhaust gas from the engine into the filtering device;
- directing a flow of gas through the filtering device from the service system;
- and
- directing sound waves into the filtering device to remove particulates from the filtering device;
- and
- carrying the particulates out of the filtering device with the flow of gas.
A system for removing particulates from a filtering device of a machine, comprising:
- an engine in flow communication with the filtering device;
- a valve located between the engine and the filtering device, the valve configured to permit a flow of exhaust from the engine into the filtering device when the valve is in a first position and the valve configured to block the flow of exhaust into the filtering device when the valve is in a second position;
- a cleaning device removably attachable to the filtering device without removing the filtering device from the machine to which the filtering device is connected;
- wherein the cleaning device is configured to remove the particulates by directing a substantially steady flow of gas and sound waves into the filtering device when the valve is in the second position.
