Abstract
Abstract A reducer cannon cleaning device is provided having a hollow handle connected to a hollow conduit, wherein the handle is connected to a source of pressurized air such that the air may flow through the handle and the conduit. Attached to the conduit opposite the handle is a generally circular plate. A gasket is disposed against the plate and the cleaning device is then placed against a filter cage and bag unit. Bursts of air can then be blown through the cleaning device and into the filter cage and bag. Several attachments can also be used with the cleaning device, some of which may be attached to the cleaning device and placed within the filter cage and bag. The various attachments may include holes therein, positioned at pre-determined locations and angles. The attachments direct and focus the air exiting the conduit and entering the filter caging unit. Another attachment is a mechanical hand unit, which can be connected to the distal end of the conduit. The mechanical hand unit can be used to crush or deform a portion of the filter cage, such that the cage may be removed from the dust collecting unit.
