APPARATUS FOR VENTILATING GRAIN OR OTHER BULK MATERIAL (VERSIONS) Russian patent published in 1998 - IPC

FIELD: agriculture, grain receiving and processing enterprises. SUBSTANCE: apparatus has at least one ventilated vessel, supplying and discharge chambers having walls common with vessel, device adapted for forming flows of ventilating medium within vessel and connected with at least one chamber, and rows of pipelines positioned within vessel one above the other. Pipelines are open from the bottom and at one end and fixed at intervals relatively offset in adjacent rows. Pipelines are connected with chambers so that pipelines of odd rows are communicated via openings at their open ends with one chamber, for instance with supplying chamber, and in even rows with other chamber, i.e. discharge chamber. According to the first version, discharge chamber is positioned at the right or left side of supplying chamber. Pipelines defining odd or even row have main collector connected with related chamber and open end of at least one pipeline of this row offset relative to mentioned chamber. According to other version, discharge chamber is positioned adjacent to supplying chamber, above or below it. Apparatus is further provided with intermediate branch pipes, each connected with supplying or discharge chamber, and at least one related pipeline, whose open end is arranged above or below chamber with which this branch pipe is connected. According to third version, pipelines are connected with their open ends to wall common for vessel and related chamber. Supplying and discharge chambers have intermediate common multiple curved wall adjoining the wall common for vessel and chambers. Multiple curved wall is extending between open ends of all adjacent pipelines in odd and even rows so that first mentioned rows belong to one chamber and second rows to other chamber. EFFECT: reduced metal usage, simplified material reversing blowing method by supplying basic medium and discharging used ventilating medium without disturbing uniform ventilation process. 9 cl, 8 dwg
