The invention relates to a preparation method and a shaping device of a
sulfur removal
nozzle. The preparation method of the low cost
sulfur removal
nozzle includes following steps: 1, firstly, smearing a
release agent on the inner surface of an outer mold and the outer surface of an inner mold; 2, obtaining mixed
powder by mixing materials, performing ball milling on the materials, and sieving the materials; 3, filling an interval between the outer mold and the inner mold with the
powder, and using a liquid pump to inject
high pressure liquid into the hollow inner mold; 4, releasing pressure; 5,
drying the mixed
powder; 6, obtaining the
sulfur removal
nozzle after
sintering the powder. The shaping device of the sulfur removal nozzle comprises a shaping mold and the
hydraulic pump, wherein the shaping mold and the
hydraulic pump are connected through a
high pressure hose, the shaping mold comprises the
metal outer mold, the rubber inner mold, a first cover plate, a second cover plate and a pressurizing connector, the
metal outer mold is composed of a first outer mold and a second outre mold, the rubber inner mold is arranged in an inner cavity of the
metal outer mold, through holes are formed in the side wall and the bottom of the metal outer mold, a second blocking round plate is further arranged on a
contact position of the second cover plate and the metal outer mold, a through hole is formed in the middle of the second cover plate, and the pressurizing connector is arranged on the outer side of the through hole in the middle of the second cover plate.
