Three return journey barrel type drying machines

Abstract

An improved three-pass cylinder dryer, including a body composed of a bracket, a sealed box and a cylinder, and its driving device, supporting device and controller, wherein the axis of the cylinder of the body is parallel to the horizontal plane, and the cylinder is arranged concentrically. The inner, middle and outer cylinders are misplaced and fitted together, and the volume cavities formed constitute three drying and dewatering units respectively. The adjacent wall panels of the inner, middle and outer cylinders are adjusted by supporting and reinforcing buffer pads. Connection and positioning, the outer circumference of the outer cylinder wall board is provided with a heat insulation cover, and the inner peripheral surface of the inner, middle and outer cylinder wall boards is respectively provided with a spiral propulsion spreader, and the rotation of the helix On the contrary, the ring gear on the outer periphery of the machine body is assembled with the center of gravity of the barrel. It effectively solves the defects of easy deformation and displacement and axial displacement of traditional drum dryers. It has reasonable structural design, stable performance, smooth process flow, large precipitation at one time, high thermal efficiency, energy saving and consumption reduction, and a wide range of applications. .

Description

technical field [0001] The invention relates to a drying device for a large amount of materials, 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 ...

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.
