<p>A cartridge filter cleaning device sprays water onto the outside of a cartridge filter as a nozzle array is moved with respect to the longitudinal axis of the filter as the filter is rotated. In an electric version, a DC motor drives a threaded rod to provide nozzle array movement, and a drive belt to rotate the cartridge filter. In a fluid-driven version, a pump provides fluid pressure for the cartridge filter rotation and nozzle array movement. Multiple cartridge filter embodiments use a single motor or pump to rotate the cartridge filters and move the nozzle array. The nozzle array provides a single nozzle or a plurality of spaced-apart nozzles for each filter. Filter orientation may be vertical, horizontal, or angled.</p> |
