A melt blown spinning multistage filtration spinneret assembly

Abstract

The utility model discloses a melt -blown spinning multistage filter spinneret subassembly, concretely relates to melt -blown spinning field, including pressure pipe and the spinneret of pressure pipe front end, be provided with at least two layers first filter piece in the spinneret rear side, be provided with second filter piece in the first filter piece rear side, the first inner silk pipe, second inner silk pipe and third inner silk pipe that are matched with spinneret, first filter piece and second filter piece are fixed in sequence on the inner wall of pressure pipe, the inside of second filter piece is provided with metal filter screen. The utility model discloses through multistage gradient filtration, and the impurity of different particle size is intercepted gradually, and the risk of spinning hole blockage is reduced significantly, and the quality of fiber is promoted, and spiral guide vane optimization melt flow path, reduce pressure loss, ensure that the filtration uniformity.
