DEVICE FOR SEPARATION OF LOOSE MATERIAL FROM CARRIER GAS Russian patent published in 2003 - IPC

FIELD: pneumatic transportation of loose materials. SUBSTANCE: proposed device includes receiving bin and loose material unloading unit, unit for additional separation of loose material which is connected with inner cavity of receiving bin through lower butt, inlet and outlet branch pipes, cyclone and filter. Unit intended for separation of loose material from carrier gas is made in form of cyclone mounted bin cover and communicated coaxially with cavity of bin by means of discharge branch pipe; cylindrical shells are located coaxially relative to discharge branch pipe; said shells form two vortex chambers which are closed in their upper part and are open to receiving bin in their lower part; they are provided with inlet and outlet branch pipes. Cyclone is connected with receiving bin through automatic dust gate. Proposed device may be provided with second cyclone fitted with individual container. Outlet cylindrical branch pipe of automatic dust gate and coaxial cylindrical shells are provided with taper bell-mouths secured for motion in vertical direction. Inlet branch pipes of cyclones are provided with spring-loaded guide blades. EFFECT: enhanced reliability and efficiency. 4 cl, 4 dwg, 1 ex
