Material crushing enhanced cyclone airflow dryer

Technical Field

The utility model belongs to the technical field of air current drying machine, a whirlwind air current drying machine is related to, specifically is a whirlwind air current drying machine of broken enhancement mode of material.

Background

The airflow drier makes wet material suspend in it by high speed flowing hot airflow, the cyclone airflow drier is one of the airflow driers, the hot airflow entrains the dried material particles to enter the cyclone drier in tangential direction, and generates rotation motion along the hot wall, so that the material particles are in suspension rotation motion state for drying. The wall of the dryer can be provided with a steam jacket according to the requirement, so as to further heat the interior of the dryer and further strengthen the drying force. In addition, the contact area of the gas and solid phases is increased due to the crushing caused by the collision of the particles with the wall of the vessel, and the drying process is also enhanced. The MST cyclone dryer is a vertical long cylindrical container which is divided into a plurality of drying chambers by conical baffles with middle holes, hot gas and wet solid materials enter the drying chamber below at a high tangential speed, a solid phase rotates in the drying chamber under the action of centrifugal force, a gas phase enters the previous layer of drying chamber through a central hole in the rotation, and meanwhile, new gas-solid materials continue to enter the drying chamber below. After a period of time, the solid phase in the lower drying chamber also begins to enter the upper layer through the central hole of the conical baffle plate, and in the drying chamber, the solid phase particles are dispersed and stop moving under the action of centrifugal force and collision with the wall of the drying chamber, and then return to the lower drying chamber through the central hole by virtue of the conical baffle plate, and are conveyed by the rotating airflow again. The solid phase particles can be crushed to a certain degree when colliding with the wall of the vessel, and the crushed solid phase particles are convenient for improving the drying effect, but the crushing degree is limited.
