Abstract

The invention relates to a countercurrent double-loop cylinder dryer, which comprises a support, an inner cylinder, an outer cylinder, a driving device, a feeding device and a discharging device, and is characterized in that: a middle cylinder is arranged between the inner cylinder and the outer cylinder, and one end of the inner cylinder and one end of the middle cylinder are respectively provided with an annular seal plate; one end of the outer cylinder is provided with a seal plate, and the three cylinders constitutes a material layer and two flue gas heating units, i.e., an inner-layer flue and an outer-layer flue; and a plurality of reinforcing supporting columns are arranged among the three cylinders for connecting and positioning, and frying plates are uniformly arranged on the outer wall plate of the inner cylinder and the inner wall plate of the middle cylinder. The problems that the material and the flue gas flow from the same pipeline, and are fully mixed, so that the dried material is mixed with impurities and the production safety is possibly generated by ineffectively controlling sparks in the flue gas to be contacted with the material and the like in the traditional drum drying machine can be solved, the structural design is reasonable, the performance is stable, the process flow is smooth, the overheating time of a dry area is long, the thermal efficiency is high, the energy is saved and the consumption is reduced, the quality of the dried material is high, and the range of application is wide.

Description

technical field

[0001] The invention relates to a drying device for a large amount of materials, in particular to a countercurrent double-circuit cylinder dryer with large precipitation range, energy saving and consumption reduction, and high thermal efficiency. It is widely used in the dehydration and drying of low-viscosity materials in pharmaceutical, light industry, chemical industry, environmental protection, feed, agriculture, forestry and other industries. Background technique

[0002] At present, the material drying device has been widely used in the dehydration and drying of low-viscosity materials in chemical industry, mining, agriculture, industry, light industry, medicine and environmental protection, and the single-layer drum dryer is the mainstream product at present. The equipment structure, equipment process and transmission system all have defects to a certain extent. First of all, there are the following deficiencies in the equipment process: the existing ...
