The application discloses a purification device and method for siliceous
sponge spicules, which adopts a purification method based on strain preparation, and has the advantages of high
recovery rate of uniaxial siliceous
sponge spicules, low broken needle rate, high purity and low breakage. The
gravity separation technology is adopted to realize large-scale industrial production. The freeze-
drying device is provided with a plurality of swing shafts symmetrically arranged on the
barrel cover, one side of each swing shaft is rotationally connected with the
barrel cover, the other side of each swing shaft is rotationally arranged on a supporting plate, a plurality of supporting rods are fixedly arranged on the swing shafts, the supporting rods are used for supporting
sponge plates, a striking table is fixed on the
barrel cover to support part of the supporting rods, a swing driving
assembly is arranged on one side of each swing shaft, the swing driving
assembly can drive the swing shaft to rotate by a certain angle and then automatically fall off, after the supporting rods fall off with the swing shaft, the supporting rods strike the striking table, so that the sponge plates on the supporting rods vibrate, when freeze-
drying is performed, the vibrating sponge plates can make the sponge turn over to a certain extent, the freeze-
drying effect is greatly improved, and the freeze-drying quality of the sponge is more uniform.
