Immersion bath tank suitable for chemical fiber composite spun short fiber

The invention discloses an immersion bath tank suitable for chemical fiber composite spun short fibers, and relates to the field of chemical fiber equipment. A plurality of U-shaped overflow clamping cavities which wrap the periphery of the cavity wall of the immersion bath tank, the cavity bottoms of the U-shaped overflow clamping cavities are communicated with the external discharge pipeline, redundant oil agents or foams enter the U-shaped overflow clamping cavities and then converge to the external discharge pipeline to be discharged to a proper recycling position in time, adverse effects of the redundant oil agents and the foams on the fiber quality are avoided, the fiber quality is improved, and the service life of the immersion bath tank is prolonged. And subsequent environment cleaning is facilitated. According to the invention, the two groups of mangle yarn guide rod assemblies are arranged at the outlet of the dipping bath tank, so that redundant oil in fibers at the outlet of the dipping bath tank
