Three return journey barrel type drying machines

Abstract

An improved three-pass cylinder drying machine comprises a machine body composed of a bracket, a sealed tank and a cylinder body, and a driving device, a supporting device and a controller, wherein the axial line of the cylinder body of the machine body is parallel to the horizontal surface, an inner cylinder and an outer cylinder that are concentrically arranged are assembled together in a staggered way to form the cylinder body, the formed cavities are used as three drying and precipitation units, the adjacent wallboards of the inner, middle and outer cylinders are connected and positioned via regulating and supporting plates and reinforced buffer plates, a heat insulating cover is disposed at the outer periphery of the wallboard of the outer cylinder, three material homogenizing and spreading machines are respectively disposed at the inner surfaces of the inner, middle and outer wallboards in a screw propulsion way and has reversed helical lines, and gears at the outer periphery of the machine body are aligned with the center of gravity of the cylinder. The inventive three-pass cylinder drying machine effectively solves the shortcomings of the conventional cylinder drying machine, including high deformation and misplacement liability and high axial dislocation liability; and has the advantages of reasonable structural design, stable performance, large precipitation range for one time, high thermal efficiency, saved energy consumptionand wide application range.

Description

technical field [0001] The invention relates to a large amount of material drying device, in particular to a three-pass cylinder dryer with large precipitation range, energy saving and consumption reduction, and high thermal efficiency. It can be widely used in dehydration and drying of low-viscosity materials in various industries, and can also be used as mechanical equipment for drying high-water content materials such as coal gasification lignite, urban garbage, and river sludge. Background technique [0002] At present, the material drying device has been widely used in the dehydration and drying of low-viscosity materials in the chemical industry, mining, agriculture, industry, light industry, medicine and environmental protection industries, and the single-layer drum dryer, which is more widely used, is the current dryer. Mainstream products on the market. However, most of them are developed by referring to the general drying technology in the 1950s, and there are cer...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an improved three-return drum dryer, which effectively solves the defects of easy deformation and displacement and axial displacement in the connection structure of traditional drum dryers.
