Thermal reactor with conveying function

Abstract

The invention relates to a thermal reactor with a conveying function, which belongs to the technical field of heating pyrolysis of brown coal, oil shale, biomass and wastes. The thermal reactor with the conveying function comprises an external heating sleeve, a sealing tank body, a feeding device and a plurality of heating plates, wherein the external heating sleeve is provided with an insulating layer; the sealing tank body is provided with a feed port and a discharge port; the main part of the sealing tank body is positioned in the external heating sleeve; one end of each heating plate is fixed on the inner wall of the sealing tank body; the plurality of heating plates are arranged in a spiral mode; and the heating plate adjacent to the feed port is extended out of the sealing tank body to form the feeding device. The thermal reactor with the conveying function has the advantages of heating a large number of materials, distributing and heating the materials uniformly, saving a heating source, avoiding the blockage of the feed port and improving production efficiency, along with high heating efficiency and wide range of adaptable materials.

Description

technical field [0001] The invention belongs to the technical field of thermal cracking of lignite, oil shale, biomass and waste, and relates to a thermal reactor with a conveying function. Background technique [0002] Most of the existing thermal reactors use screw conveyors with auger structure. Its structural features: spiral blades are welded on the rotating shaft of the screw conveyor, and the blades have solid surface type, belt type, etc. Surface type, blade surface type and other types. The screw shaft of the screw conveyor has a thrust bearing at the end of the material movement direction to give the opposite force to the screw shaft with the material. During the conveying process of granular or powdery materials, the rotating helical blades push the materials for screw conveying. Due to the weight of the material itself and the frictional resistance of the screw conveyor casing to the material, the material cannot rotate with the blades of the screw conveyor very...
