Description

[0001]
[Industrial applications]
The present invention relates to an apparatus suitable for transferring a granular material.
[0002]
[Prior art and problems]
Conventionally, there is a so-called screw conveyor as one of the devices of this type. In this screw conveyor, a lead member spirally wound around a rotating shaft and mounted is worn over time and the outer diameter is reduced. And the transport volume is halved as a result. In addition, there is a problem that it takes time and effort to manufacture the lead member, and the work of fixing the lead member to the rotating shaft is very troublesome.
[0003]
The present invention has been made in view of the above circumstances, and has as its object the purpose of using a spiral-shaped lead member, and having a transfer capability substantially equal to that of a screw conveyor, and also providing a powdery or granular object that is easy to manufacture. It is to provide a transfer device.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, a transfer device for a granular material according to the present invention is a device for transferring a granular material, wherein the gutter has a U-shaped cross section, extends horizontally, and has a discharge port at one end. A rotating shaft extending along the trough and rotatably supported in a vertical plane; having a substantially semi-elliptical plate-like shape, and having a longitudinal axis on the front side of the rotating shaft. Fixed at predetermined intervals along the direction, inclined at an angle equal to or greater than the angle of repose of the particulate material or the friction angle with the particulate material with respect to the rotation axis, and the center of the diameter is cut out to reduce the diameter. And a plurality of first feed blades that are substantially semicircular about the center of the rotating shaft when viewed from one end of the rotating shaft. Having a substantially semi-elliptical plate-like shape, on the rear side of the rotating shaft, along the longitudinal direction thereof; The first feed blade is fixed at a necessary interval and is inclined at an angle substantially equal to the angle formed by the first feed blade on the opposite side of the first feed blade with respect to the normal to the rotation axis, and has a diameter of The vicinity of the center is cut off so that a part of the diameter is located near the center of the body of the rotating shaft, the vicinity of the leading end of the diameter is connected to the vicinity of the leading end of the diameter of the first feed blade. And a plurality of second feed blades having a substantially semicircular shape about the center of the rotation axis when viewed from one end.
[0005]
With such a configuration, when the first feed blade and the second feed blade are continuously rotated in the vertical plane around the rotation axis via the rotation shaft, the powdery and granular material in the trough firstly After being scooped up by the first feed blade, it slides down on the first feed blade, falls from the lower end thereof, and the granular material dropped from the lower end is similarly scooped up by the second feed blade. Then, it slides down on the second feed blade and falls from the lower end thereof. By repeating the above operation, the granular material is transferred in the trough.

The first feed blade 3 has a substantially semi-elliptical plate shape, is fixed to the front side of the rotary shaft 2 at a predetermined interval along the longitudinal direction thereof, and is fixed to the rotary shaft 2. On the other hand, it is inclined at an angle equal to or greater than the angle of repose of the particulate material or the friction angle with the particulate material, so that the center of the diameter is cut off and a part of the diameter is located near the center of the body of the rotary shaft 2. Further, when viewed from one end of the rotating shaft 2, it has a substantially semicircular shape centered on the center of the rotating shaft 2 (see FIG. 2).
[0008]
As shown in FIG. 1, the second feed blade 4 has a substantially semi-elliptical plate shape, and is fixed to the rear surface of the rotary shaft 2 at a required interval along its longitudinal direction. The first feed blade 3 is inclined on the opposite side of the first feed blade 3, 3 about the normal line of the rotating shaft 2 at substantially the same angle as the angle formed by the normal line, and near the center of the diameter. Is cut off so that a part of the diameter is located near the center of the body of the rotating shaft 2, the vicinity of the leading end of the diameter is connected to the vicinity of the leading end of the first feed blade 3, and the rotating shaft 2 Has a substantially semicircular shape about the center of the rotating shaft 2 when viewed from one end (see FIG. 2).
[0009]
With such a configuration, when the first feed blade 3.3 and the second feed blade 4.4 are continuously rotated around the rotation shaft 2 in the vertical plane via the rotation shaft 2, the trough 1 First, the granular material in the inside is scooped up by the first feed blade 3, then slides down on the first feed blade 3 and falls from the lower end thereof. After being scooped up by the second feed blade 4, it slides down on the second feed blade 4 and falls from the lower end thereof. By repeating the above operation, the granular material is transferred in the trough 1.
[0010]
In the above-described embodiment, the first feed blades 3.3 and the second feed blades 4 are provided one by one on the rotating shaft 2 at a required interval in the longitudinal direction thereof , and these first feed blades 3 The first feed blade 3.3 and the second feed blade 4.4 have a structure that constitutes a single substantially spiral object as a whole, but as shown in FIG. the Oite disposed the two first feed blade 3, 3 group and the second feed blade 4, four groups or two or more first feed blade 3, 3 groups and the second feed blade 4.4 groups, Two substantially spiral bodies which are displaced from each other by a predetermined distance in the longitudinal direction of the rotary shaft 2 are formed, that is, a plurality of first feed blades 3 and a plurality of second feed blades 4 are formed to form a single spiral. substantially as a two-rowed forming the helical body, a plurality of first feed blade 3, 3 and the second feed blade 4.4 that of Re each other so as to place the regular intervals is mounted on the rotary shaft 2. More to this, it is possible to further improve the transport capacity. And
The above-mentioned substantially spiral object may be provided in three or more lines.
