The invention relates to a
helix for transporting a high-temperature material, which comprises a main shaft and a
helical blade fixed outside the main shaft. The main shaft is a double-sleeve hollow shaft, an outer sleeve of the main shaft and the
helical blade are integrally manufactured by an overlaying
welding technique, a main water inlet
pipe is arranged in an inner sleeve of the main shaft, a cooling return water passage of the main shaft is formed between the two sleeves, a hollow water-cooled tank is arranged in the
helical blade along the surface of the outer sleeve of the main shaft, the outlet end of the main water inlet
pipe is provided with a
flow divider, cooling water is divided into two flows by the
flow divider, the two flows enter the cooling return water passage of the main shaft and the hollow water-cooled tank of the
helical blade respectively, and the two flows of cooling return water are merged and discharged at a water outlet of the cooling return water passage of the main shaft. The
helix has the advantages of reasonable structure, good
water cooling effect, large effective working area of the blade, high abrasion resistance performance, high discharging working efficiency, full play to double advantages of a material and a structure, and long service life.
