Utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of simple in structure, easy and simple to handle and staple fibre wet spinning device that spinning quality is good.
The utility model solves the technical scheme that its technical problem adopts: a kind of staple fibre wet spinning device, comprise manifold, described manifold is provided with coagulating bath, plasticizing-bath, rinsing bowl and successively around winding apparatus, described manifold connects coagulating bath by pipeline, on pipeline, be provided with crane span structure and candle filter, pipeline end is provided with spinneret assembly, and described crane span structure is provided with measuring pump;
Described coagulating bath is provided with acid inlet tube and returns acid tube, returns acid tube end and is connected with acid-restoring plant;
Described plasticizing-bath is provided with front stretching rod and after-drawing rod, and plasticizing-bath liquid level top is provided with cover cap, and cover cap is connected with waste gas recovering device.
Further, described rinsing bowl and be provided with hot roll between winding apparatus.
Further, described waste gas recovering device is carbon disulfide gas retracting device.
Further, described acid inlet tube is positioned at coagulating bath bottom, is convenient to feed in raw material.
Further, described manifold is built-in with agitator, and spinning solution is stirred.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, by manifold, coagulating bath, plasticizing-bath, rinsing bowl with around the cooperation of winding apparatus, realize spinning solution to the process of spinning, and easy and simple to handle, cost is low, and fibre strength is large.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
