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.)

1. A method of vacuum-pneumatic transportation of bulk materials of high mass concentration comprising
pneumatically transporting the bulk material through a transporting pipeline from an original zone with atmospheric pressure into a receiving zone, creating a vacuum in the receiving zone maintaining a stable concentration in mass in the transporting pipeline by fluidization materials wherein vacuum in the receiving zone is created by alternate actions of impulses from at least two vacuum receiver, wherein each of said at least two receivers is connected to a continuous vacuum source connected by pipes with quick-acting valves to the receiving zone in such a manner that while a vacuum impulse is acting from one of the receivers on the receiving zone, each of the said at least two receivers synchronously disconnects from continuous vacuum source during the time of the vacuum impulses and another of said at least two receivers is connecting to the continuous vacuum source.
