Vertical single-channel material turnover dryer

Abstract

The invention relates to the field of material dryers, in particular to a vertical single-channel material turnover dryer. The dryer comprises an outer barrel and an inner barrel, a hot air inlet is formed in one of the inner and outer barrels, an exhaust gas outlet is formed in the other one of the inner and outer barrels, a material channel is formed between the inner barrel and the outer barrel by encircling, more than two partitions are distributed in the material channel and around an axis of the inner barrel, and at least one material guide structure used for guiding dried materials to turn over and flow is arranged between the upper end and the lower end of each partition. During use, when the materials fall from the top the material channel into the material channel and pass through the same, the material guide structures on the partitions guide the materials to turn over during falling to enable the materials to fall and turn over simultaneously, and when exchanging heat with hot air, the materials mutually exchange heat through sufficient mixing in the turnover process, so that utilization rate of a heat source can be increased greatly, speed for feeding the materials into the material channel is increased, and production efficiency of the vertical dryer is improved.

Description

technical field [0001] The invention relates to the field of material dryers, in particular to a vertical single-channel material tumbling dryer. Background technique [0002] In the production fields of building materials, metallurgy, chemical industry, printing, briquette, etc., it is often necessary to dry materials with a certain particle size. Vertical dryers are commonly used drying equipment in the above-mentioned production fields. The continuous improvement of energy and efficiency requirements has also been developed rapidly. [0003] The gravity dryer disclosed in the Chinese patent application with the publication number CN101017054A is one of the common vertical dryers. The retaining ring, the distributing cone on the top of the retaining ring, and the lifting plate on the inner wall of the cylinder, among which a hot air channel is formed in the retaining ring, and a The material channel, the cylinder body is provided with a waste gas outlet, and the hot air ...

AI Technical Summary

Problems solved by technology

However, the setting of the retaining ring and the lifting plate will still affect the full contact between the hot air and the material, and the above-mentioned double-tube vertical dryer still has the problems of low drying efficiency and waste of energy.
