Description

Technical Field

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

[0002] After being crushed, quicklime forms quicklime particles with a particle size of 5-15 mm. The quicklime particles can be made into slaked lime after digestion. The quicklime particles formed 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 silo is discharged for use after temporary storage and accumulation, sometimes it is inconvenient to unload, and a rubber hammer needs to be used to vigorously knock on the silo to facilitate discharge, increasing the manual workload. The quicklime particles formed after crushing are then sent to a digestion device for digestion. The existing quicklime digestion device can use a horizontal double-shaft mixer plus sprayed water for digestion reaction, but the existing double-shaft mixer often has the situation that the sprayed water is too concentrated and the spraying part is easily blocked by quicklime and is not easy to clean, thus affecting the use of the digestion device. The quicklime particles formed after crushing are then sent to a digestion device for digestion and then dried. Most of the existing slaked lime drying devices use a screw conveyor form for stroke drying, and such drying may result in uneven drying and incomplete drying of some slaked lime.
