Same-cavity integrated vertical walnut shell high-speed multi-stage superfine grinding device and method

Abstract

The invention discloses a same-cavity integrated vertical walnut shell high-speed multi-stage superfine grinding device and method. The same-cavity integrated vertical walnut shell high-speed multi-stage superfine grinding device comprises a double-channel sliding type feeding device and a same-cavity integrated vertical grinding device body, the same-cavity integrated vertical crushing device body comprises a material raising disc and a same-cavity integrated vertical crushing barrel body, a first-stage coarse crushing area, a second-stage fine crushing area, a third-stage pneumatic impact micro-crushing area and a fourth-stage jet mill superfine crushing area are arranged in the same-cavity integrated vertical crushing barrel body, walnut shells falling through the double-channel slidingtype feeding device are evenly raised into a wedge-shaped gap of the first-stage coarse crushing area through the material raising disc to be coarsely crushed, the second-stage fine crushing area achieves fine crushing on the coarsely crushed materials through a two-stage wedge-straight-through gradually-shrinking gap, the third-stage pneumatic impact micro-crushing area impacts the walnut shellfine crushed particles at a high speed, the walnut shell fine crushed particles are impacted and violently rubbed under carrying of high-speed airflow to be crushed, in the four-stage jet mill superfine grinding area, micro-particle grading is achieved through arc-shaped blades, and micro-particles meeting the particle size condition are sucked out through negative pressure attraction.

Description

technical field [0001] The invention belongs to the technical field of ultrafine grinding of walnut shells, and in particular relates to a high-speed multi-stage ultrafine grinding device and method for integrated vertical walnut shells in the same cavity. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Walnut, also known as walnut and Qiang peach, is the first of the four major dry fruits in the world, and it is also an important economic tree species in my country. In recent years, researchers at home and abroad have conducted in-depth studies on the physical and chemical properties of walnut shells, and found that their chemical properties are stable, do not contain toxic substances, and their solubility in acid or alkaline solutions is extremely low, and will not cause water quality deterioration. It has the potential value of in-dep...
