Abstract

The invention discloses a device for realizing the online cyclic utilization of rare earth polishing stock. The device is composed of a stock tank (1), a stock mixing tank (2), a cyclone separator (3), a first press filter (4), a fine filter (5), a second press filter (6), a homogenizing agent hopper (9) and a powder adding head (12). The invention further discloses a method for using the device. The online cyclic utilization of the rare earth polishing stock can be directly realized by the device in the stock state, and the device can be directly used for matching with a polisher to recycle the polishing mortar, therefore the recycling times of a polishing mortar system can be greatly improved. According to the device, an aim of recycling the stock can be achieved by sectionally getting rid of invalid components and invalid particles in a stock system, and the device has the technical characteristics of high efficiency, quickness and low energy consumption; meanwhile, wastewater and effluent discharge can be avoided in the process of online cyclic utilization, and the production requirements on the clean whole process are met.

Description

technical field [0001] The invention relates to a device for realizing on-line recycling of rare earth polishing slurry, and a method for using the device, which is suitable for recycling polishing mortar in cooperation with a polishing machine, and improves the recycling times of the polishing mortar system. Background technique [0002] As rare earths are widely used in various fields, the consumption of rare earths is increasing year by year, and China's consumption of rare earths has ranked first in the world. Rare earth polishing powder (mainly cerium-based rare earth polishing powder) is widely used in the precision polishing of glass devices such as electronic glass, optical glass, jewelry and precision instruments due to its unique physical and chemical properties and excellent polishing performance. Known as the "King of Polishing Powder". [0003] The use of rare earth polishing powder first needs to be mixed with water to prepare "polishing slurry". The polishing...
