CONTAINER ROTATION-TYPE MIXER AND HEAT TREATMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a container rotation-type mixer which is capable of efficiently stirring/mixing a material to be stirred.;SOLUTION: This container rotation-type mixer 10 is characterized in that not only the churning-up and precipitation operation of a granular material by a lifter plate 30 is repeated inside a rotary drum 11 but also the granular material is transferred to the discharge orifice 11B side by an inclined guide projecting piece 34, and then the granular material is transferred to a feed pocket 11A side by a spiral guide 20. In short, the convection (circulation) of the granule in the axial direction of the rotary drum 11 takes place. In addition, the stirring/mixing process of the granular material is promoted by the repetition of its dispersion/gathering during the movement of a plurality of the lifter plates 30 passing through the granular material layer. Consequently, this invention is far more variety-rich in terms of a flow pattern of the granule, compared with the conventional-type mixer which is limited only to the repeated churning-up/precipitation operation. Thus, it is possible to perform the efficient stirring/mixing process of the granular material with this new mixer and achieve the homogeneous mixing of the granular material in a shorter time than by the conventional-type mixer.;COPYRIGHT: (C)2009,JPO&INPIT
