Abstract

The invention provides a rotary heating device which comprises a housing, a rotary material bed and a support piece, wherein the housing is provided with an inner chamber; the rotary material bed is arranged in the inner chamber of the housing; at least part of the support piece is arranged in the housing, and supports the rotary material bed which can rotate; a cooling cavity for accommodating a refrigerant is formed in the support piece. The rotary heating device has the advantages that flexion and collapse generated during the rotation process of the rotary material bed of the rotary heating device in the prior art are avoided effectively, and the problem of insufficient strength of the support structure in a high-temperature environment is solved.

Description

technical field [0001] The invention relates to the technical field of processing equipment, in particular to a rotary heating device. Background technique [0002] Rotary heating devices are generally used for processing solid materials at high temperature and normal pressure, such as coal pyrolysis and drying. The driving device drives the rotating tray to rotate around the axis by driving the discharge pipe, so that the materials on the rotating tray are dried or pyrolyzed through direct contact with the hot gas. Since the weight of the rotating tray is supported on the discharge pipe located at the axis, when the amount of material supported on the rotating tray is too heavy, the discharge pipe will buckle and collapse due to excessive load, and the rotating tray will therefore Forced to stop, and because the working environment of the rotating material bed is generally high temperature, there have been problems with insufficient strength of some support structures in h...
