| 摘要 |
The present invention relates to a plant for the transport of granular material comprising at least one container (100) for at least one granular material (1a) to be transported, at least one receiver-meter group (RD1, RD2, . . . , RDn) designed to receive granular material from said at least one container (100), at least one conveyance duct (L1, L2, . . . , Ln) of said granular material from said at least one container (100) to said at least one receiver-meter group (RD1, RD2, . . . , RDn), depressurization-pressurization means (11, 11a) arranged to suction/inject a gaseous medium from/into said at least one container (100), and at least one vacuum duct (LV; LV1, LV2, . . . , LVn) between said at least one receiver-meter group (RD1, RD2, . . . , RDn) and said depressurization-pressurization means (11, 11a), thereby creating a flow of said granular material and said gaseous medium in said at least one conveyance duct or line (L1, L2, . . . , Ln) directed to said at least one receiver-meter group (RD1, RD2, . . . , RDn) and a flow of gaseous medium between said at least one receiver-meter group (RD1, RD2, . . . , RDn) and said depressurization-pressurization means, the plant comprising detection means of parameters of said flow (MP; VT1, VT2, . . . , VTn) located in said at least one vacuum duct or line (LV; LV1, LV2, . . . , LVn), adjusting means of the power (DV) of said depressurization/pressurization means and electronic control means (ECU) designed to receive in input control signals from said speed detection means (MP; VT1, VT2, . . . , VTn) and to emit control signals in output for driving said adjusting means (DV).
