1. A same-cavity integrated vertical high-speed multistage superfine pulverizing device for walnut shells, comprising:
a double-channel sliding type feeding device and a same-cavity integrated vertical pulverizing device, wherein
the double-channel sliding type feeding device comprises a first spiral inclined chute and a second spiral inclined chute, which are oppositely arranged and configured to allow walnut shells to slide down through the first spiral inclined chute and the second spiral inclined chute into the same-cavity integrated vertical pulverizing device;
the same-cavity integrated vertical pulverizing device comprises a material lifting disc and a same-cavity integrated vertical pulverizing barrel, wherein the same-cavity integrated vertical pulverizing barrel is internally configured with a first-stage coarse crushing region, a second-stage fine crushing region, a third-stage pneumatic impact micro pulverizing region and a fourth-stage airflow mill superfine pulverizing region;
the material lifting disc is configured to uniformly lift the walnut shells that have slid down through the first spiral inclined chute and the second spiral inclined chute into a wedge-shaped gap of the first-stage coarse crushing region, wherein the first-stage coarse crushing region is configured to coarsely crush the walnut shells to produce coarsely crushed materials, and the second-stage fine crushing zone is configured to finely crush the coarsely crushed materials through a two-stage wedge-shaped direct-through gradually reducing gap to obtain finely crushed walnut shell particles;
the third-stage pneumatic impact micro pulverizing region is configured to perform high-speed collision on the finely crushed walnut shell particles, and the finely crushed walnut shell particles are subjected to collision and violent rubbing while being carried by a high-speed airflow for pulverizing; and
the fourth-stage airflow mill superfine pulverizing region is configured to perform microparticle grading is using arc-shaped blades, and to attract out microparticles conforming to a particle size condition using negative pressure attraction.
