Nanoscale dynamic centrifugal separation device

Abstract

The invention relates to the field of ball mills, in particular to a nanoscale dynamic centrifugal separation device. The nanoscale dynamic centrifugal separation device comprises a horizontal separation cylinder with an open end. The other end of the separation cylinder is sealed. A discharging port is formed in the end face of the other end of the separation cylinder. The other end of the separation cylinder is fixedly connected with a rotary discharging shaft. The discharging port is communicated with an inner cavity of the discharging port shaft. An inner cavity in one end of the separation cylinder is covered with a screen. A separator is fixedly arranged in an inner cavity in the other end of the separation cylinder. A separation cavity of the separator is communicated with the discharging port. When materials and grinding media in a grinding cavity enter a pre-distribution region of the separation cylinder, the grinding media and materials with large particles can be blocked at the pre-distribution region through the screen, and pre-separation of the materials is achieved; and the pre-separated materials with the small particles enter the separation cavity of the spiral separator, multi-stage separation is achieved, and thus the nanoscale separation effect is achieved.

Description

technical field [0001] The invention relates to the field of ball mills, in particular to a separation device of a ball mill. Background technique [0002] Ball mill is widely used in paint, paint, rubber, abrasive, ceramics, ore, coal powder, metal powder, hard alloy, magnetic material, food, daily chemical, dye, ink, medicine, magnetic material, soft ferrite material, photosensitive Film and other industrial fields. Existing grinders include dry type and wet type. The working principle of the wet type ball mill is to use the stirring and grinding method. When the stirring shaft rotates at high speed, it drives the grinding medium called "sand" and the object to be ground (slurry) to make a vortex. Movement, so that the grinding medium moves from bottom to top along the inner cylinder wall under the action of centrifugal force, and falls down under the action of its own gravity when it reaches the liquid surface. During this process, the grinding medium moves back and for...

Problems solved by technology

However, the existing separation devices generally use gap separators, which directly separate materials and grinding media, which not only has poor separation effect, but also has low separation efficiency.
