Rotary drum drying device

Abstract

The invention discloses a rotary drum drying device which comprises a feed bin, a large rotary drum body, a feed end plate, an air inlet, a plurality of small rotary drum bodies, an air outlet, a discharge end plate and a discharge outlet. The small rotary drum bodies are combined with the large rotary drum body to form a combination. The axis of each small rotary body is parallel with that of the large rotary drum body. The small rotary drum bodies are disposed in the large rotary drum body. The front end and the rear end of the combination are sealed to form a sealed bin. The feed bin is mounted at the front-end extension part of the small rotary drum bodies. The discharge outlet is formed at the rear-end extension part of the small rotary drum bodies. The discharge end plate for controlling discharge amount and timing is disposed between the rear ends of the small rotary drum bodies and the discharge outlet. The rotary drum drying device is simple in structure, easy to operate, and wide in adjustable range, indirect contact drying is used, materials are operated in a slide manner, fume with low oxygen content is used directly, and environment protection requirements are met.

Description

technical field [0001] The invention relates to the technical field of mechanical drying. The utility model relates to a drum drying device, which is suitable for occasions where there is no broken dry material. Background technique [0002] At present, when used in the chemical industry, double-cone rotary dryers are basically used for drying granular, powdery or wet products obtained after chemical reactions. The amount of dried material in the double-cone rotary dryer is small, and the material is often bonded to the inner wall of the dryer, which deepens the color of the inner wall and affects the quality of the dried product. Moreover, the larger the bonded block, the more difficult it is Discharge. [0003] In order to overcome the above-mentioned defects of bonding, most of them currently use a rotary drum drying process. For example, Chinese patent application No. 200910258096 discloses a rotary drum dryer, which has a heat source, a discharge device, and a fan de...

AI Technical Summary

Problems solved by technology

[0004] However, the conventional drum dryers currently in use have the following disadvantages: the drying time is relatively short, which makes the material dry insufficiently; The rotary drum dryer is also prone to damage and drying during the drying process
