Compared with the prior art, the inferior heavy oil fluidization conversion technology has the advantages of simple process, low investment, strong raw material adaptability, good product distribution and good environmental benefits.

The invention relates to production equipment for manufacturing excellent optical fiber preforms by a VAD (vapor axial deposition) method. The production equipment comprises a seed rod, a blank rod, atransmission mechanism, a supply mechanism, a heating mechanism and two supporting mechanisms. The supply mechanism comprises a gear, a supporting shaft, a rack, a translation unit and at least two oxyhydrogen flame blast burners. The translation unit comprises a first motor, a first connecting rod and a second connecting rod. The heating mechanism comprises a heating ring and at least two heating components, and each heating component comprises a regulating plate, an X-ray detector, a laser emitter and a regulating unit. The production equipment for manufacturing the excellent optical fiberpreforms by the VAD (vapor axial deposition) method has advantages that the supply mechanism enables the oxyhydrogen flame blast burners to rotate, reaction gas is supplied to each position at the bottom end of the blank rod, uniform attachment of dust on the outer periphery of the seed rod is benefited, heating conditions at each position of the outer periphery of the blank rod are controlled through the heating mechanism, the reaction degree at each position is controlled according to production conditions to enable uniform attachment of dust on the surface of the seed rod, and accordingly optical fiber preform production quality is improved.
