MIXER FOR PRODUCING CELLULAR CONCRETE MIX Russian patent published in 2001 - IPC

FIELD: materials of construction. SUBSTANCE: mixer has cylindrical case, charging device, compressed air feeder, discharging device, drive shaft that mounts mixing blades and foam-making members. Novelty is that mixing blades are made of flexible rubber plates or cable thimbles with weights fastened in loose end part of blades to ensure straightening of blades in viscous medium of cellular concrete mix in the course of rotation of drive shaft at minimum 550 rpm; foam-making members are made in the form of small turbines mounted in bottom part of drive shaft at distance of 10-15 cm from mixing blades. Mixer is multipurpose device that can function as mixing device, hydromechanical activator, foam maker, expander tube pump delivering foam concrete mix through mud channel at distance proportional to gage pressure. EFFECT: enlarged functional capabilities and porosity range of cellular concrete. 1 dwg
