Description

Technical Field

[0001] The utility model relates to the field of lime treatment equipment, and particularly relates to a quicklime storage and digestion device. Background Art

[0002] After quicklime is crushed, quicklime particles with a particle size of 5-15 mm are formed. The quicklime particles can be prepared into slaked lime after digestion. The formed quicklime particles after crushing often need to be stored in a temporary storage bin and then sent to a digestion device for digestion. When the existing quicklime particle bin is discharged for use after temporary storage and accumulation, sometimes the unloading is inconvenient, and a rubber hammer needs to be used to vigorously knock on the bin to facilitate the discharge, which increases the workload of manpower. The formed quicklime particles after crushing are then sent to a digestion device for digestion. The existing quicklime digestion device can use a horizontal double-shaft mixer and spray water for the digestion reaction, but the existing double-shaft mixer often has the situation that the spray water is too concentrated and the spray part is easily blocked by quicklime and is not easy to clean, thus affecting the use of the digestion device.
