Pull the sliding rod 602, the sliding rod 602 drives the clamping column 603 to move, so that the clamping column 603 disengages from the fixing hole, and then the filter box 503 is taken out, which is convenient for the staff to handle the impurities on the filter box 503 and avoid the impurities from blocking the filter holes and affecting the conveyance of the flue gas.
