A chemical fiber filament waste cleaning device includes a material container with a material inlet at one end and with a material outlet at the other end; a mainshaft driven by the motor is assembled in the middle center of the container; the blade spirally circled along the axial mainshaft; the container consists of two coaxially installed cylinders of an internal housing and an external housing; the peripheral of the internal has holes; a plurality of water spraying mouths are opened in turn on the top of the container from the external housing through the internal housing; by the spraying mouth, a plurality of water guns carry out the high-pressure washing to the poured chemical fiber filament waste from top to bottom. A draining mouth is opened at the bottom of the external housing and is connected with the hydroextractor; the chemical fiber cut into short pieces are poured from the material pouring mouth, the blade rotates along the mainshaft to transport the raw material from the material inlet to the material outlet and to get the qualified products by high-pressure washing. The utility model has the features of simple structure, low manufacture cost, good cleaning effect, no environmental pollution and recyclable waste water.
