The invention discloses a continuous conveying device for heat treatment of materials under a protective atmosphere, comprising: a furnace body, the furnace body is defined with an accommodation chamber for accommodating materials, and the furnace body has an air inlet, an air outlet, and The feed inlet, the discharge outlet, and the air inlet introduce protective gas into the accommodating cavity, and the central axis of the furnace body is arranged obliquely relative to the horizontal direction; In the accommodation chamber, the flight shaft is provided with multiple flight plates suitable for mixing materials; the sealing assembly is set on the flight shaft and connected with the furnace body; the heater is installed outside the furnace to heat the material ; The driver is connected to one end of the shaft of the copy board. According to the embodiment of the present invention, the continuous conveying device for heating and treating materials under a protective atmosphere can not only fully heat the materials, but also establish a stable protective atmosphere and temperature environment, and realize the continuous treatment process of heating while conveying the materials.
Description
technical field [0001] The invention relates to the technical field of material processing equipment, and more specifically, relates to a continuous conveying device for conveying materials while heating under a protective atmosphere. Background technique [0002] A large amount of dioxins produced during waste incineration will be adsorbed on the surface of fly ash, making fly ash the main carrier of dioxin emissions. Relevant studies have shown that continuous heat treatment of fly ash in a high-purity nitrogen atmosphere for a period of time can achieve a high rate of desorption of dioxins, thereby realizing the harmless treatment of fly ash. At present, domestic waste incineration plants do not have a kind of equipment for heat treatment of fly ash under protective atmosphere to realize the harmless treatment of fly ash. Contents of the invention [0003] The invention aims to realize the industrialization of harmless treatment of fly ash at least to a certain extent....
