Abstract

An intelligent separation device has gas explosion, stirring, drying and negative pressure adsorption devices. The gas explosion device receives conveyed peanut materials with red coats to be removed, and the materials are subjected to gas explosion, so that the peanut kernels and the peanut red coats are preliminarily separated. The stirring device shifts the preliminarily separated peanut kernels and peanut red coats into the drying device. The drying device compresses and heating external air, transfers heat through hot air, and heats and dries the preliminarily separated peanut kernels and peanut red coats, so that the peanut red coats and the peanut kernels are fully separated. The negative pressure adsorption device collects the fully separated peanut kernels and red coats with different densities and masses in a negative pressure adsorption mode.

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.
