The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of blue charcoal production blower fan main body of centrifugal blower, comprise the casing of bringing wind sidewall and exhaust outlet into, be arranged at impeller in the casing, be arranged on the air intake sidewall front shroud, be fixed on air intake tube on the front shroud, be arranged on the back shroud of casing air intake sidewall opposite side, it is characterized in that: described air intake tube is near the fixing aluminium cover of the outer surface of impeller one end; Described front shroud and described housing are provided with sealing gasket at the junction plane place; Described casing and described back shroud are structure as a whole, and between described back shroud and the impeller drive shaft sealing configuration are set.
The utility model can also adopt following technological scheme:
Sealing configuration between described back shroud and the impeller drive shaft comprises cover in the sealing of being fixed on the impeller drive shaft, forms with cover in the sealing and radially slides the hermetically sealed case that cooperates, and between the left side of described hermetically sealed case and the back shroud seal ring is set; On the right side of described hermetically sealed case oil sealing is set, described oil sealing is pressed on the right side of described hermetically sealed case by gland.
Several radial gussets are set on the outer surface of described front shroud.
Advantage and the good effect that the utlity model has are:
The aluminium cover is set between air intake tube and impeller, produces spark when preventing the friction of impeller and air intake tube, the coal gas that ignites guarantees the Security of blower fan; Between front shroud and casing sealing gasket is set, back shroud and casing are made of one structure, between back shroud and the impeller drive shaft sealing configuration are set, and adopt above-mentioned seal approach, avoid the coal gas in the blower fan to leak, and cause environmental pollution.
