Title:
CYCLONIC FLOW FIELD-BASED SUPERFINE POWDER WET TYPE ELECTROSTATIC GRADING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/083015
Kind Code:
A1
Abstract:
Provided is a cyclonic flow field-based superfine powder wet type electrostatic grading device, which belongs to the field of superfine powder grading equipment. The device comprises a cylinder body (5); the cylinder body (5) is a hollow cavity, a material conveying shaft (2) and a rotary shaft (14) are arranged in the cylinder body (5), the side wall of the cylinder body (5) is provided with material outlets (4, 6, 7), a deceleration motor (11) is arranged at the lower end of the cylinder body by means of a machine frame (10), and a first electrode piece (15) is arranged at the inner wall of the cylinder body (5); a spray head structure (16) is arranged between the material conveying shaft (2) and the rotary shaft (14), the rotary shaft (14) is connected with the deceleration motor (11) by means of a coupling (9), and a second electrode piece (3) is arranged at the outer wall of the material conveying shaft (2) and the rotary shaft (14); the spray head structure (16) is used for spraying the material into the cylinder body (5) to form a cyclonic flow, and each grade of powder after grading is discharged out of the material outlets (4, 6, 7) by grades and is collected. The device integrates into one body a cyclonic flow field and wet type electrostatic grading, superfine powder grading efficiency is effectively improved, and multi-grade collection of graded products is realized, the structure is compact, and operation is simple.
