[0001] The utility model relates to the technical field of sintering machine head ash slurry treatment, in particular to a rapid precipitation device for sintering machine head ash slurry. Background Art
[0002] During the sintering production process, the sintering head will produce sintering head ash slurry. The particle size of the sintering head ash slurry is 1000-1500 mesh, with strong viscosity and easy to suspend. In industrial processing, chemicals (anionic polyacrylamide and polyaluminum chloride) are added to mix with the sintering head ash slurry, and then the sintering head ash slurry containing chemicals is pumped to the sedimentation tank for sedimentation through a mud pump.
