[0024] Working principle: When work is needed, the user assembles the whole structure, and quicklime can be introduced through the quicklime bin 1, and the quicklime guide seat 5 can introduce the refined quicklime. The quicklime in the quicklime bin 1 can be transmitted to the position of the variable frequency rotary feeder 3 through the manual plug valve 2, and then the variable frequency rotary feeder 3 is opened. The quicklime can then be guided to the acceleration chamber 7 through the exhaust chamber 4.
