APPARATUS FOR CLEANING FILTERS IN PRESSURIZED FLUID FLOW SYSTEMS |
摘要 |
<p>The reverse flow cleaning process is initiated either automatically by a timing or pressure sensitive device, or manually, by opening an outlet which allows the flow of water, thereby creating a pressure difference. The pressure difference not only creates a reverse flow from the clean to the dirty filter side, but also moves a wiping element having a smaller inlet area than the surface of the filter across the latter surface at a controlled speed. The return of the wiper element to the original position is accomplished either by a spring or hydraulic reset element. Damping is provided to insure that the motion of the wiper is a slow, steady motion. In a special construction, the wiper element consists of a multiplicity of individual elements elastically pressed against the inside, dirty side of a hollow cylindrical filter. The wiper elements are mounted in a piston-like element which moves in response to the pressure difference carrying the wiper elements with it.</p> |
