PNEUMATIC MULTI-PRODUCT CLASSIFIER Russian patent published in 2007 - IPC B07B9/02 

FIELD: chemical industry; construction industry; mining industry; metallurgy industry; other industries; devices for the multi-product air classification or separation of the dispersed materials.

SUBSTANCE: the invention is pertaining to the devices for the multi-product air classification or separation of the dispersed materials and may be used in construction industry, mining industry, chemical industry, metallurgy industry and other industries. The pneumatic multi-product classifier includes: the loading module having the rectangular horizontal section; at least two opposite walls, which are supplied with the pouring components and-or of the profiled shape, for example, with formation of the pouring components directed towards the formed by them separation channel having, at least, one loading fitting pipe and at least one fitting pipe or the window for the air supply; and mounted over the loading module one main separation module supplied, at least, with one fitting pipe of withdrawal of the air with the fine fraction of the separation, or several located one above another main separation modules, the upper of which is supplied with at least one fitting pipe of withdrawal of the air with the fine fraction of separation. The main separation module supplied, at least, with one fitting pipe of the air withdrawing fitting pipe with the fine fraction of separation contains one or several bodies of the cylindrical either conical or the cylinder-conic shape with, at least, one device for formation of the aerodispersive stream with the vertical axis of rotation. The main separation module supplied, at least, with one fitting pipe of withdrawal of the air with the fine fraction of separation, and the below disposed main separation or the loading module are conjugated among themselves by means of the contraction tube. The technical result of the invention is the increased quality of separation and extension of the range of usage of the classifier.

EFFECT: the invention ensures the increased quality of separation and extension of the range of usage of the classifier.
