INSTALLATION FOR RECEPTION AND TRANSPORTATION OF LOOSE BUILDING MATERIALS Russian patent published in 2007 - IPC B65G53/08 B65G53/48 

FIELD: civil engineering; pneumatic transport.

SUBSTANCE: invention can be used in transportation of viscous and dry building materials set erecting a high-rise building. Proposed installation includes receiving silo with pneumatic screw pump and receiving and mixing chambers interconnected by cylindrical housing with pressure auger with screw blades. Pressure consists of two sections, one of which is provided with blade arranged along single-start spiral. Other section of auger installed from side of mixing chamber is provided with screw blades arranged along double-start spiral. Shaft of said section is made in from of cone, taper angle of 10°-15° and length equal to 0.5-0.7 of diameter of auger.

EFFECT: increased distance of transportation of materials and reliability at provision of required capacity and exclusion of material losses.
