<p>Apparatus for filtering industrial liquids and gases by separation of suspension particles based on the principle of radial stationary filtering. The invention concerns a filtering apparatus consisting of a cover (9), a body (6) and a base (19) whose volume is adjustable by altering the length of its body (6). A threaded rod is provided for sealing the unit and also for providing a sealed joint between the filter element (4), the cover (9) and the base (19). The threaded rod (2) can be tightened and untightened using a butterfly handle (11) without the use of other threaded connections. Depending on the liquid or the gas to be filtered, the filter medium will be made from towel-type paper or felt. The filter elements (4) come in a single size and a spacer device (22) is used to provide different lengths. The liquid or gas to be filtered is conveyed by a conical transmission conduit (16) past a circular rib (13) into the outer peripheral zone of the filter chamber (5). It then transits through the filter element (4) at right angles to the different layers of the latter to emerge in the central shaft (3). The filtered liquid or gas is discharged through a conical discharge pipe (18) through radial channels (12) and axial channel (21) in the threaded rod (2). The filtering apparatus of the invention provides, in particular, an effective, low cost solution to the problems of industrial filtering, with an objective of quality, long service life of industrial gases or liquids, or for ecological purposes.</p> |
