Abstract

The invention provides a rotary feeder sealed by an air curtain, which includes an arc-shaped impeller rotor composed of arc panels, inner and outer panels, a hollow shaft, etc., a casing, a material inlet and outlet, a rotary joint, and a tapered sleeve. The rotary joint is connected with the hollow shaft, the hollow shaft is provided with an air inlet, the arc impeller rotor is provided with arc panels evenly distributed along the circumference, and the inner panel is provided with waist-shaped holes and arc-shaped grooves corresponding to the arc panels. The panel is stuck in the arc groove; there is an axial gap between the tops of each adjacent two arc panels as the air flow channel for the axial sealing air curtain, and an annular gap is provided between the inner and outer plates as the air flow for the end face sealing air curtain aisle. The arc-shaped impeller rotor is detachably connected through a tapered sleeve, double-ended studs, and nuts. The sealing effect of the two pressure air curtains of the present invention is good, the rotor does not contact the inner surface of the shell, has no wear, the parts have a long service life, the rotor is flexible in operation, easy to disassemble and clean, and can be used as a non-contact rotary sealing air lock feeding device.

Description

technical field [0001] The invention relates to a rotary feeder, in particular to a rotary feeder sealed by an air curtain, and belongs to the technical field of material conveying equipment. Background technique [0002] Rotary feeder is also called rotary feeder and rotary feeder. Its internal key component is the rotor with multiple radial blades. The material in the upper bin falls by its own weight and fills the cavity between the blades. The material moves along with the rotor. The rotation is discharged from the lower material port. The rotary feeder is simple in structure and small in size. It is widely used in occasions requiring small pressure difference between the inlet and outlet. It is often used as an air-lock feeding device for closed conveying systems in industries such as tobacco, grain, cement, and road construction. [0003] In order to ensure the flexible operation of the rotor, a certain gap must be left between the rotor and the housing, but materials...
