Most anticorrosive centrifugal fans have the same function and frame structure, but are different in materials or some parts. The special reason for the anti-corrosion centrifugal fan is that it is made of plastic, most of which have undergone anti-corrosion treatment. The air intake box of the anticorrosive centrifugal fan is also made of plastic material, which has both advantages and disadvantages. It is necessary to find a way to transform its air intake box. How to transform the air inlet box of the anticorrosive centrifugal fan?
(1) From there to the anticorrosive centrifugal fan impeller, all solid particles in the air come from the surrounding inner pipeline. There is a long track in front of the entrance of the anticorrosive centrifugal fan impeller. Just before the entrance of the anticorrosive centrifugal fan impeller, the device used to have a long track with a diameter of 200 mm.
②Conical filter with holes. A cylindrical cavity for placing clothes is installed in the center of the air intake box. The cone screen has achieved good results twice. The particle size is in the cylindrical gap, and a small amount of solid particles in the gas solid at the entrance of the atmosphere box are absorbed from the gas box by the anti-corrosion centrifugal fan impeller. The central installation of the anti-corrosion centrifugal fan air inlet box is being innovated, and a cylindrical gap with a filter is installed. How to transform the air inlet box of the anticorrosive centrifugal fan? Under the action of the fan-shaped filter screen, the particles in the natural gas tank core are sent away along a horn coupler called a cone, and the purified atmosphere is screened out and put into the cylindrical hollow port. In this way, the particles dispersed at the inlet of the centrifugal fan are lower at both ends and higher at the surrounding positions.
(3) When the blades of the driven wheel and the impeller are close together, the wheels will be flattened by the blades of the blades. At the same time, it sounds, sucks in dirty air from the air duct, and forms a shielding pad at the front of the impeller disk streamline. This modification method uses this modification method to change the cyclone at the entrance of the impeller, and uses the fan inlet box to coil 200 mm cylindrical particles and solid particles into cylindrical air and send it to the anticorrosive centrifugal fan. The advantage of a certain method is that it can check the dirty gas of the impeller from the shape of the deep breathing channel outside the cylindrical cavity, with the entrance of the anticorrosive centrifugal fan as the core.
