Manufacture method and device of three-dimensional workpiece

The invention provides a method and equipment using organic adhesive mixed solvent and powder to manufacture three-dimensional workpieces. The work principle is as follows: the raw materials are stirred into slurry, which is laid as a green compact thin layer that can disintegrate in disintegrant; the green compact thin layer can form a workpiece thin layer that does not disintegrate in the disintegrant after scanned by an energy beam; in such a cycle, the steps of laying the thin layer and energy beam scanning are repeated, and then the three-dimensional workpiece can be formed; and the disintegant is used for separating the green compact not scanned by the energy beam from the workpiece, thus remaining the needed three-dimensional workpiece. The invention is widely applicable to manufacturing plastic, metallic, ceramic and compound workpieces, can avoid the defects of a selective laser sintering method, can use fine and very thin powder and therefore, can manufacture a finished product which is better than that made in the traditional selective laser sintering method in surface roughness and texture fineness, in addition, through subsequent densified sintering, the metallic and ceramic workpieces can have the strength superior to that in the traditional selective laser sintering method.

Ultralow bath-ratio yarn dyeing machine with three-level vane pump

The invention discloses an ultralow bath-ratio yarn dyeing machine with a three-level vane pump, comprising a dye vat, a yarn stand and a vane pump, wherein the bottom of the yarn stand is a yarn stand disk; the yarn stand disk is provided with a hole communicated with a dye liquor input channel in the dye vat; the vane pump is arranged below the whole dye vat and is a three-level vane pump; a shaft of the three-level vane pump is connected with an internal motor shaft coaxially; the dye vat is connected with the inlet of the three-level vane pump; the three-level vane pump comprises an axial flow level, a centrifugal level and a fixed guide vane level; the axial flow level and the centrifugal level are connected with the motor in sequence through the same transmission shaft; dye liquor flows into the axial flow level through an in-flow channel; the dye liquor flowing out of the axial flow level directly enters the inlet of the centrifugal level; and the dye liquor flowing out of the centrifugal level enters an out-flow channel after passing through the fixed guide vane level. During work, the dye liquor in the dye vat does not exceed the yarn stand disk all the time and the bath ratio is lower than 1:3. The ultralow bath-ratio yarn dyeing machine can achieve required lift when the dye liquor in the yarn dyeing machine is lower than a spindle, so as to realize the low bath ratio of the yarn dyeing machine as well as the purpose of saving energy and reducing emission.
