摘要： An injection molding filtration apparatus having a filter, a decompression passage, and a filter check valve is used to filter molten polymer, while allowing for more complete decompression of the equipment downstream from the filter. The filter check valve and decompression passage are preferably internal to the filter element itself. In alternative embodiments, the decompression passage may be a separate bypass line that is arranged in a parallel configuration with an oppositely directed bypass check valve. Preferably, each of the check valves uses the molten polymer to push a movable body into a sealing engagement with an internal wall of the valve.

摘要： A backflushable filtering apparatus for a molten material, particularly for a plastic melt, comprises a housing (1) in which a sieving arrangement (17) is provided which includes at least two sieving sections (16) separated from one another. The melt to be filtered is supplied to the sieving sections (16) through at least one distributor (3). The distributor (3) includes at least one control body (9) for backflushing which is moveable within a housing (53) that is provided with an inlet opening (4) for the material to be filtered. The control body (9), in a filtering position, unblocks the influx of material to be filtered to all sieving sections (16) through connection channels (23). However, in a backflushing position, the control body (9) interrupts the influx of material to the filtering section (16) to be backflushed and interconnects the connection channel (23) of the sieving section (16) flushed back with a discharge channel (28) located in the control body (9). At least the majority of the circumference of the control body (9) is surrounded by a distribution space (7) for the material to be filtered which is situated within its housing (53). The distribution space (7) is connectable through the connection channels (23) to all sieving sections (16) in communication with the distributor (3). Guiding channels (6) lead from the inlet opening (4) to the regions of the two front ends (61, 62) of the distribution space (7). These front ends (61, 62) are situated in the region of the outermost connection channels (23) or outside the region of all connection channels (23). The discharge channel (28), which leads away from the control body (9), may be caused to communicate with the connection channel (23) of the respective sieving section (16) to be flushed back through a flush back channel (27) of at least one cross-piece (14) of the control body (9) which overbridges the distribution space (7).

摘要： The invention relates to an arrangement for filtering plastic melts. Dirty filter elements (4, 4) can be liberated from collected dirt particles by means of backwashing. The melt (8) used for backwashing is deviated from the main melt flow and can optionally and additionally be impinged upon by conveying elements. Backwash is periodically initiated according to the time and/or the degree of soiling of the filter element to be cleaned. The aim of the invention is to improve the inventive arrangement in such a way that cleaning is optimal according to the degree of soiling of the filter element to be cleaned respectively. A control device (7) is provided which detects the melt volume and/or the flow rate of the backwashing melt during a backwashing procedure.

摘要： Recently, in terms of improving the yield and production rate of a biaxial-oriented polypropylene pearly synthetic paper, since the inorganic powder itself has an unsteady dispersion property while blended with polypropylene and while the extruder raises its production rate, which causes a shorter period of replacing the filter screen of the extruder; consequently, frequently replacing the filter screen deteriorates the efficiency of production, further obstructs the goal of increasing the yield from being achieved. The key technique of the present invention on the achievement of improving the yield and production rate of the pearly synthetic paper is to prefabricate the inorganic powder into a master-batch (M1B) in the manufacturing process of the pearly synthetic paper; in addition, the inorganic powder is merely blended with polypropylene (primary raw material) to reach the required dispersion in advance; the present invention improves the problem of manufacturing process of conventional pearly synthetic paper of which the extruded sheet from the extruder has pores and air spots structure caused by the moist inorganic powder or the heat-volatilized gas produced from the surface treatment agent which would otherwise affect the product quality, the yield and production rate. Consequently, while the extruder is being operated under a status of the maximum rotating speed and the maximum extrusion output, the inorganic powder master-batch (M1B) of the present invention which has in advance fulfilled the dispersion requirement is able to effectively improve, incorporated with a design of air-drawing device and an increased blending effect of a double-screw, the yield and production rate of the biaxial-oriented polypropylene pearly synthetic paper. In addition, the present invention innovates in using an inorganic master-batch (M1B) which is prefabricated and has a better dispersion property not only largely to lengthen the using period of the filter screen of the extruder but also to resolve the problem of causing an abnormal production due to stopping the operation of production line for replacing the filter screen; therefore, the manufacturing method disclosed by the present invention is able to directly increase the rotation speed of the extruder and further increase its yield effectively.
