Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the prevention of co-rotation of a granular feeder.

[0002]

2. Description of the Related Art In a conventional granular material feeder, as a mechanism for preventing co-rotation of the granular material, there is a type in which a rectangular pillar-shaped projection is provided vertically on the inner surface of an inner cylindrical portion. Sometimes caused consolidation.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to stably discharge a powdery material which is going to rotate together with a rotating blade without causing consolidation.

[0004]

According to the present invention, in order to achieve the above object, an inner cylinder for supplying powder and granules is provided on a bottom plate through a gap, and an outer cylinder sharing a center line with the inner cylinder is provided. The lower end is connected to the bottom plate, and an annular passage for the granular material discharged from the gap is formed between the inner and outer cylinders, a discharge port is provided in the passage, and the upright rotating body protrudes from the center of the bottom plate. a central rotating blade provided, the outer peripheral rotary ring along the inner circumferential surface of the outer tube to the tip of the rotary blade is provided, met granular material feeder comprising by directing a plurality of the outer peripheral rotating blade inside which is provided on the rotary ring A powdery or granular material comprising: an isometric resistance plate that intersects a plurality of radial lines having an equal opening angle in the same direction with an equal angle on the upper surface of the bottom plate, and the central rotating blade is disposed immediately above the resistance plate. The feeder is constituted by a resistance plate for preventing the co-rotation of the granular material.

[0005]

[Function] The powder starting to rotate together with the rotating blade (in the direction of arrow A) is carried to the resistance plate. Since the resistance plate is attached obliquely, a force acts on the powder and granules in the outer peripheral direction (arrow B), so that stable discharge is possible.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An inner cylinder 2 for supplying powder and granules is provided on a bottom plate 7 with a gap t interposed therebetween. The gap t between the cylinders 1 and 2
An annular passage p for the granular material discharged from the container is formed, and a discharge port 8 is provided in the passage p.

At the center of the bottom plate 7, an upright conical rotating body c having a conical upper end is protruded, and a radially rotating central rotating blade 4 is provided on the rotating body c. An outer peripheral rotating ring 6 is provided along the surface, and a plurality of outer peripheral rotating blades 5 are directed inward to the rotating ring 6 to form a granular material feeder.

The opening angle α is equal to (60
6) The equal-length resistive plates 13 intersecting each other in the same direction at an equal angle α ′ on a plurality of radial lines d are provided.
The central rotating blade 4 is disposed immediately above the central rotating blade 3.

[0009] In addition, what is indicated by 3 in the figure is a flow control ring,
9 is a discharge chute, 10 is a speed reducer, 11 is an electric motor, 12
Is a safety cover.

[0010]

[Effects of the Invention] Since the present invention is configured as described above, stable discharge can be performed without consolidation.
