Description

Technical Field

[0001] The utility model relates to the technical field of staple fiber stretching, in particular to a staple fiber drafting water bath. Background Art

[0002] In the short fiber stretching process, the drafting water bath is located between the first drafting machine and the second drafting machine. Its main function is to heat the filament bundle to above the glass transition temperature for stretching. After the short fiber stretching process, the liquid in the water bath has more and more impurities in the lower layer of the water bath and more foam in the upper layer, so it is necessary to adjust the height of the short fiber bundle in the water bath.

[0003] In the prior art, when short fibers enter the water bath for drawing, impurities will enter the water bath. As the water bath runs for a long time, the impurities at the bottom of the water bath will gradually increase. The impurities in the water bath need to be cleaned up by regular shutdown. However, the shutdown of the water bath for impurity removal will waste a long time, thereby affecting the drawing processing efficiency of the short fibers in the water bath. For this reason, we propose a short fiber drawing water bath. Utility Model Content

[0021] The box chamber of the cover box 4 gradually shrinks from the side low port 3 toward the external connecting pipe 5; the short fiber impurity liquid flowing out of the side low port 3 can flow along the cover box 4 into the external connecting pipe 5 for collection.

[0022] Among them, the flange ring 6 of the external connecting pipe 5 and the flange plate at the sewage inlet end of the sewage valve 7 are flange-connected by bolts and nuts; after the bolts pass through the flange ring 6 and the flange plate at the sewage inlet end of the sewage valve 7, the nuts can be screwed on to achieve flange connection.
