Document Type and Number:
WIPO Patent Application WO/2019/071706
Kind Code:
A1
Abstract:
Disclosed in the present invention are a high temperature-resistant axial flow fan applied to a watercraft desulfurization system, comprising a fan shell, axial flow blades, high temperature-resistant bearings and a cold water pipe. The axial flow blades are coaxially arranged at the inner front end of the fan shell, and a rotary shaft is inserted between the axial flow blades; two high temperature-resistant bearings are sleevingly arranged in the middle of the rotary shaft; a cross-shaped axis support is fixed to the outer sides of the two high temperature-resistant bearings; a worm wheel is sleevingly arranged at the rear end of the rotary shaft, and a worm is disposed at the upper end of the worm wheel; the worm wheel is engaged with the worm; both the worm wheel and the worm are disposed inside of a lubricating oil shell; the lubricating oil shell is wrapped in a thermal insulation layer; the cold water pipe is arranged in the thermal insulation layer in a coiling manner; and the two ends of the cold water pipe penetrate out of the fan shell and form a cold water pipe water inlet and a cold water pipe water outlet respectively. The present invention has a simple and compact structure and occupies a small space, may notably improve the discharge efficiency of fumes, and has a wide applicability when applied to the watercraft desulfurization system.
