Recycling Equipment with Filtering and Washing on Fine Powder of Rare Metal and Technological Design

Abstract:

In order to meet the needs of recovery production of filtering and washing of fine powder of rare metal, a device has been developed which is a set ultra-fine filter, mixing washing, dry-pressed cake, cake discharge and microporous regeneration, etc. in one integral device, and all steps can be completed once using it in a confined space. In addition, a number of key technologies were advanced that can be realized by the device, including recycling technologies, polymer ultra-fine filter technology, equipment and structural design, workflow design, etc. The device has many advantages, such as high filtration precision, high recovery rate, high efficiency production, simple operation, high degree of automation and less environmental pollution. Fine powder of rare metal is generally prepared by electrochemical or chemical production method, wherein filtering and washing are two important processes. Filtering, washing, recovery technology and equipment progressiveness have a direct impact on products quality, resources loss, energy consumption, costs, environment and other problems. Design of a new ultra-precision filtering and washing equipment of fine powder of rare metal and its advanced recycling technology are of great significance.
