Conveying graft for use in the case of pneumatic conveying of solids and pneumatic conveying method with the use of the conveyor plug.

摘要

PURPOSE:To hinder the biting in of a solid material even when the solid material is filled in from a material input port by providing at least one auxiliary column on the rear part of two columns that specify material storing space, and by coupling these columns together through a soft coupling material. CONSTITUTION:Measured solid material is input and filled in between two columns 11 and 12 that specify the material storing space (a) of a transfer column, from a material input port formed on the starting end of a transfer pipe. A transfer column A is pneumatically transferred at low speed by supplying a pressurized transfer gas in the transfer pipe. The solid material leaked and thus dropped at the time is stored in the space (b) between the rear column 12 and an auxiliary column 13.
