Abstract

The invention discloses a metal particle spiral conveyor used in a high-temperature environment and belongs to the technical field of material conveying. The conveyor comprises a fixed support, a fixed sealing head, a shaft, a spiral blade, a movable sealing head, a driving device, a movable sealing head adjusting device, a cooling water connector, a water-cooled cover, a sealing rope, a sealing nitrogen connector, a sealing nitrogen nozzle, an adjusting support, a positioning bolt and an adjusting air cylinder. The conveyor has the advantages that a variable-frequency and variable-speed motor is adopted as a power supply, the spiral blade is cooled in a direct and indirect combined mode and is designed to be of a multi-end structure, and the adjusting air cylinder is arranged; in this way, the overall service life of the conveyor is significantly prolonged, the frequency of examining and maintaining the spiral blade is greatly reduced, maintenance cost is greatly reduced, meanwhile, the annual operating rate of a rotary hearth furnace production line is improved, and the manufacturing cost of finished products is further reduced.

Description

technical field [0001] The invention belongs to the technical field of material conveying, and in particular relates to a metal particle material screw conveying device used in a high-temperature environment. Background technique [0002] At present, domestic and international rotary hearth furnaces used for dust control or direct reduction of iron all use spiral discharge equipment to transport the high-temperature materials distributed on the hearth of the rotary hearth furnace to the outside of the furnace. During the operation, the discharge is often dirty, Severe spiral wear and leakage of furnace gas seriously affect the stability of production and operation. The spiral blades of the currently used spiral discharge equipment are mostly connected to the shaft by bolts, resulting in insufficient cooling of the spiral blades, and long-term friction with metal particles in a high-temperature environment, resulting in a relatively short service life; most of the spiral disc...
