Device and method for removing large micro-powder particles

Abstract

The invention discloses a device for removing large micro-powder particles. The device comprises a stirring cylinder, a separation cylinder, a siphon pipeline and a water adding pipeline, the bottom of the stirring cylinder communicates with a slurry pipeline, a slurry pump is installed on the slurry pipeline, and a pre-stirring mechanism used for pre-stirring micro-powder slurry is further installed on the stirring cylinder. Two separation cavities distributed side by side are formed in the separation cylinder, the upper portions and the middle portions of the separation cavities are cylindrical, the lower portions of the separation cavities are in a circular truncated cone shape, a fixedly-arranged separation stirring shaft is installed in each separation cavity, the bottom of each separation stirring shaft extends to the bottom of the corresponding separation cavity, and a separation stirring paddle is fixedly installed at the bottom of each separation stirring shaft. The top of each separation stirring shaft extends to the outer side of each separation cavity, and a separation stirring power mechanism used for driving the separation stirring shafts to rotate is fixedly installed on the separation cylinder. The device for removing the large micro-powder particles is simple in structure and convenient to operate, large particles in micro powder are removed through repeated water adding, settling and siphoning treatment of the micro powder through the separation cylinder, and the production purity of the micro powder is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of micropowder production, in particular to a device for removing large particles of micropowder, and also relates to a method for removing large particles using the device for removing large particles of micropowder. Background technique [0002] Micropowder is a micron-sized abrasive material, generally referring to abrasive particles with a size less than 63μm. According to the material, it mainly includes brown corundum micropowder, garnet micropowder, slag micropowder, etc. The processing of abrasive micropowder has three characteristics: the product has fine particle size, narrow particle size distribution, and no impurity pollution. [0003] At present, in the production process of micropowder, it is necessary to remove and purify the large particles in the micropowder, especially for the grinding and polishing of precision materials. Scratches on the surface of precision materials lead to processing...

Problems solved by technology

[0003] At present, in the production process of micropowder, it is necessary to remove and purify the large particles in the micropowder, especially for the grinding and polishing of precision materials. Scratches on the surface of precision materials lead to processing failure. It is necessary to re-grind the scratched surface, and then re-grind and polish, which will cause waste of resources and increase costs.
