[0034] Insertion and fixation: precisely insert the sliding seat 3 into the outer box body 1 to complete the abutment assembly, and realize stable fixation through the magnetic force adsorption of the magnetic block 303.

[0035] Motor connection: when installing the sliding seat 3, use the driven coupling 305 to coaxially connect the agitator 304 and the stirring motor 4.

[0036] II. Working principle of waste gas treatment

[0037] Control mechanism: set the intermittent action logic of the four groups of electric cylinders 201 through the program:
