Abstract
The present invention discloses a same-cavity integrated vertical high-speed multistage superfine pulverizing device and method for walnut shells. The same-cavity integrated vertical high-speed multistage superfine pulverizing device for walnut shells includes a double-channel sliding type feeding device and a same-cavity integrated vertical pulverizing device. The same-cavity integrated vertical pulverizing device includes a material lifting disc and a same-cavity integrated vertical pulverizing barrel. 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 are disposed in the same-cavity integrated vertical pulverizing barrel. Walnut shells falling through the double-channel sliding type feeding device are uniformly lifted by the material lifting disc to a wedge-shaped gap of the first-stage coarse crushing region to be coarsely crushed, and coarsely crushed materials are finely crushed by the second-stage fine crushing region through a two-stage wedge-shaped direct-through gradually reducing gap. The third-stage pneumatic impact micro pulverizing region performs high-speed collision on finely crushed walnut shell particles, and walnut shell fine particles are carried by a high-speed airflow and are collided and violently rubbed to be pulverized. The microparticle grading is realized by the fourth-stage airflow mill superfine pulverizing region by using arc-shaped blades, and microparticles conforming to a particle size condition are attracted out through negative pressure attraction.
