Abstract

1386143 Filters for use in extruders WERNER & PFLEIDERER 14 April 1972 [22 April 1971] 17336/72 Heading B5A [Also in Division B1] Molten plastics material to be extruded or injection-moulded is forced by screw shaft 6 from casing 5 through filter elements 1 into orifices in plate 7, the filter elements being received in holes distributed equidistantly in a holder 2, the arrangement being such that the filter elements extend across the entire crosssection of fluid flow. Each filter element comprises a cylindrical basket 1a, Fig. 5, made of perforated metal and preferably having a diameter of 20 to 30 mm., this basket being provided at its open end with a collar 1b for fitting into the holder 2. As shown, each basket 1a contains an inner basket 1c comprising a layer of wire mesh 1d and an inner layer of fine filter cloth 1e, both sharing a collar 1f. Fig. 1 shows two sets of filter elements, each set being received in a holder 2 supported in a recess in a slide 4. When the upper filter elements become clogged, the slide is moved upwards so that the lower set of elements is interposed between the extruder and the orifice plate 7; the soiled filter elements can then be cleaned or replaced. Fig. 6 (not shown) illustrates equipment wherein the liquid-being-filtered flows from the outside into the interior of the filter elements; and wherein the slide is actuated by an hydraulic or compressed-air cylinder. Fig. 8 (not shown) illustrates a tapering filter element wherein the support basket forms the inner layer of the element. Fig. 9 (not shown) illustrates equipment wherein the filter element holders are inserted in a slide of circular cross-section which is guided in a casing containing duets for heating fluid.
