Abstract
The invention discloses a wheel hub anti-corrosion hood for isolating corrosive gas. The wheel hub anti-corrosion hood comprises a pot-cover-shaped anti-corrosion hood upper half, two anti-corrosion hood lower halves, multiple sealing rings and multiple sealing gaskets, wherein a pan shape is formed after the two anti-corrosion hood lower halves are fixed together. The two anti-corrosion hood lower halves are fixed together through corresponding upside-down edges and the corresponding sealing gaskets by means of bolts and nuts. Each vane paddle sleeve is fixed into a whole paddle sleeve mounting hole in a clamped manner through the corresponding sealing ring, wherein each whole paddle sleeve mounting hole is formed by a paddle sleeve mounting hole half A and a paddle sleeve mounting hole half B. The transmission shaft is fixed into a whole transmission shaft mounting hole in a clamped manner through the corresponding sealing ring, wherein the whole transmission shaft mounting hole is formed by a transmission shaft mounting hole half A and a transmission shaft mounting hole half B. The wheel hub anti-corrosion hood is mounted on a draught fan, and a wheel hub of the draught fan can be prevented from being in direct contact with gas flow containing corrosive media; the wheel hub of the draught fan is prevented from being corroded; the service life of the wheel hub of the draught fan is prolonged; and furthermore, the service life of the draught fan is prolonged.
