In the invention, the adjusting plate 124 can be pulled outwards at the telescopic position in the hollow dustproof plate 125 by loosening the wing screw 126, after the position is determined, the wing screw 126 can be locked to ensure the dustproof effect, the bending position of the side folded plate 121 in the U-shaped mounting seat 123 through the movable bolt nut 122 can be adjusted by loosening the movable bolt nut 122 to ensure the side protection effect, finally the movable bolt nut 122 is locked to ensure the dustproof protection effect, a proper amount of cooling liquid is injected into the cooling tube body 134 by taking off one of the liquid injection caps 135, then the liquid injection cap 135 is screwed, the cooling box 133 can be continuously filled with cold air through the action of the cooling liquid, and then the heat dissipation fan 136 is started to act through the heat dissipation fan 136, so that the cold air is blown upwards into the hollow heat dissipation frame 132 through the heat dissipation fan 136 and enters the shell 2, the filter body 3 can be cooled and radiated to ensure the working stability of the filter body 3, the gas circulation effect can be ensured through the ventilation net 131, the cooling and radiating effect can be ensured, the adjustment can be carried out according to the requirement of the installation and fixing position, the position of the square-head bolt 147 on the outer wall of the linear support 146 can be slidably adjusted through loosening the square-head bolt 147, the distance between the square-head adjusting seats 145 is shortened, the installation and the fixing are convenient, the square-head bolt 147 can be fixedly installed through the installation hole 143, finally the square-head bolt 147 is locked to meet the requirement of the fixed installation, when the filter body 3 is influenced by external force, the connecting seat 151 can press the shock-absorbing rod 152 to move in the shock-absorbing spring 153 and the fixed sleeve 154, the buffering operation can be carried out, the limiting effect can be achieved through the retaining ring 155, the buffering and the shock-absorbing effect can be ensured, and, and the buffering and damping effect is ensured.
