METHOD FOR THE VACUUM-PNEUMATIC TRANSPORTING OF BULK MATERIALS WITH A HIGH MASS CONCENTRATION

摘要

Invention refers to the pneumatic transport field, namely to vacuum-pneumatic transportation of bulk materials of high mass concentrations. Summary of the invention consist in that the material delivering from zone under atmospheric pressure into zone under vacuum is performed, at that vacuum is created by alternate action of vacuum impulses from one of two or more vacuum receivers connected to continuous vacuum source in such a way that under vacuum impulse action from one of receivers it synchronically, for the vacuum action duration period, disconnects from continuous vacuum source and the following receiver connects to continuous vacuum source. Invention allows transporting the bulk material of high concentrations through pipelines of long distances and having the sections of changeable transportation directions (vertical, slope.)
