Study of Water-sealed Cyclone
Water-sealed cyclone is a new efficient equipment to use for grading, concentrating of slurry, it was researched and developed by the Kunming Metallurgy Research Institute in the 1980s, and accessed to the 1990 national invention award and the national patent products (ZL02245313.X). The equipment and technology are innovative, firstly, we design a set of micro-pressure (0.005～0.008MPa) water-sealed device, which eliminates the gas phase of three-phase of solid-liquid-gas of the traditional general hydrocyclone grading process, it only has solid and liquid phases. Secondly, the axial velocity envelope surface which is a factor of controlling the accuracy of grading changes to a wedge rotation; and the interface of upward flow to down flow changes from surface to the solid, it can improve grading accuracy. Thirdly, water-sealed box and catheter devices make the stilling which pass through the cyclone cone centrifugal force fields re-enter the pressure grading zone of catheter. The three innovations make water-sealed cyclone can reduce the loss of overflow and has less mud in stilling product. Because the excellent performance, the water-sealed cyclone has application in non-ferrous metals, ferrous metals, non-metallic and aluminum hydroxide industries for grading, desliming and concentrating since it has successfully developed.
