The invention belongs to the technical field of spiral conveyors, and particularly relates to a spiral conveyor for a
rotary kiln, which comprises two bases symmetrically arranged; the spiral conveyor for the
rotary kiln further comprises a conveying mechanism, the outer wall of the conveying mechanism is fixedly connected with the top of the base, by arranging the conveying mechanism, the cooling
assembly is filled with cold water, materials are cooled from the interior, the scraping
assembly is arranged in the cooling
assembly and scrapes the inner wall of the cooling assembly, incrustation adhesion is avoided, and the
cooling efficiency is improved. Water in the cooling assembly is closer to the edge of the cooling assembly, so that the
water flow in the cooling assembly is reduced, the consumption of cooling water is reduced, the weight of the cooling assembly is reduced, the load of a driving motor is reduced, the
diameter of a
spiral blade can be increased when the lengthening assembly extends, disintegrating
slag in a conveying
pipe is thoroughly conveyed, and the service life of the conveying
pipe is prolonged. And the inner wall of the conveying
pipe is cleaned, and the interior of the conveying pipe is kept clean.
