The brush 304 sweeps off the slaked lime adhering to the inner wall of the screening chamber 3. The staff can open the screening chamber 3 through the door body 307 to discharge the granular impurities, thereby improving the purity of the slaked lime and further improving the quality of the slaked lime.

[0025] Working principle: The staff feeds quicklime into the interior of the feeding chamber 1 through the feeding port 101. At this time, the first motor 102 drives the rotating shaft 104 to rotate. The rotating shaft 104 drives the spiral plate 103, the first stirring blade 202, and the scraper 203 to rotate. The spiral plate 103 pushes the quicklime into the interior of the stirring chamber 2. After the quicklime is converted into slaked lime inside the stirring chamber 2, it enters the interior of the screening chamber 3. The second motor 302 drives the second stirring blade 303 to agitate the slaked lime. The fully digested powdered slaked lime is discharged from the discharge port 301 through the sieve plate 305, and the remaining granular impurities remain inside the screening chamber 3. The staff can open the screening chamber 3 through the door body 307 to discharge the granular impurities, thereby improving the purity of the slaked lime and improving the quality of the slaked lime.
