Double-scattering structure-type rotary cylinder dryer with shaft cooling

Abstract

The invention discloses a double-scattering structure-type rotary cylinder dryer with shaft cooling, comprising a frame, wherein the frame is provided with a rotary cylinder and a motor I for driving the rotary cylinder to rotate; a shovelling plate is arranged on the inner wall of the rotary cylinder; scattering devices are arranged inside the rotary cylinder; two groups of scattering devices are provided and each scattering device comprises a rotating shaft and a drive device; the drive device is connected with the rotating shaft; an axis of the rotating shaft of each scattering device deviates from the axis of the rotary cylinder; the axis of each rotating shaft is parallel to the axis of the cylinder body of the rotary cylinder; a bracket is arranged on each rotating shaft; scattering teeth are arranged on the bracket; each rotating shaft is a hollow revolving shaft; one end of the hollow revolving shaft is provided with a cooling medium outlet and the other end of the hollow revolving shaft is provided with a cooling medium inlet; a cooling medium is arranged in the hollow part; the drive device comprises a drive motor II, a small belt pulley, a belt and a large belt pulley; the small belt pulley is connected with the drive motor II; and the large belt pulley is connected with the rotating shafts. The double-scattering structure-type rotary cylinder dryer has the advantages of simple structure, convenience in manufacturing and maintenance and high heat exchange efficiency, and reliability in quality.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a rotary cylinder dryer with a double-scatter structure used for cooling wet and viscous materials with a shaft. Background technique [0002] Rotary cylinder dryer is a large category of traditional drying equipment, widely used in various industries. At present, many rotary cylinder dryers used in China are composed of a rotary cylinder and its rotating device. The inner wall of the rotary cylinder is equipped with a lifting or distribution type lifting board device. When the rotary cylinder rotates, the lifting board device It also rotates with the rotary cylinder and lifts the materials to be dried in the dryer. With the further rotation of the rotary cylinder, under the action of its own gravity, the materials to be dried will be thrown off the lifting plate device and fall to the bottom of the rotary cylinder. After that, with the rotation of the rotary cylinder,...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to solve the problems of uneven particle size and water content, low thermal efficiency, and overheating and denaturation of materials in the prior art dryer, and to provide a drying effect for blocky, paste-like and viscous materials with large particles. The unique double-scattered structure rotary cylinder dryer with shaft cooling; it has the advantages of simple structure, convenient manufacture and maintenance, high heat exchange efficiency and good product quality.
