A shelf type drier countercurrently with movable shelves for drying agglomerates of low mechanical strength

摘要

A dryer box counter-current with mobile shelves (8) for drying agglomerates of low mechanical strength equipped with an upper loading zone (2) for wet aggregate and a discharge zone (4) for dry aggregates divided in a number of drying zones (3) with a nozzle gas inlet (5) and an outlet nozzle gas (6), in which a preferably rectangular (1) vertical box comprises a loading top ( 2) at least one, preferably two levels, a drying zone (3) of multiple levels, preferably two to six levels area and a bottom discharge (4) of at least one, preferably two levels, in which inlet nozzle to provide (5) drying gases is located between the area of ​​bottom discharge (4) and the drying zone (3) and the outlet nozzle (6) for the extraction of wet gases is located between the drying zone (3) and the upper loading zone (2), wherein the shelves (8) of the loading area (2) and shelves (10) of the discharge zone (4) are constituted by a number of metal plates of rectangular plates and non-perforated shelves (9) area drying (3) are constituted by a number of perforated metal plates and rectangular panels, and each of the shelves rectangular plates (8-10) is attached along its long edge to parallel pins (11) mounted oscillating in the walls of the box (1), in transverse relationship with respect to an axis of the housing (1) so.
