BACKGROUND OF THE INVENTION
The present invention relates to a valve device for a granular material such as a synthetic resin raw material.
[0002]
[Prior art]
Conventionally, the following is known as this type of valve device. That is, it has a casing having an inlet at the upper part and an outlet at the lower part, and a slide partition plate which is provided in the guide part of the casing so as to be horizontally slidable and partitions the casing up and down. Things are known.
[0003]
[Disadvantages of the prior art]
The conventional valve device has the following drawbacks. That is, since the slide partition plate is slidably supported by the guide portion of the casing, the granular material that has entered between the slide partition plate and the guide portion of the casing is crushed by sliding of the slide partition plate. In addition, there is a drawback that the slide partition plate does not operate smoothly due to the granular material entering between the slide partition plate and the guide portion of the casing. And there was a problem that the dust generated by crushing the granular material has an adverse effect on the processing and processing of the granular material.
[0004]
[Means for eliminating the above-mentioned drawbacks]
The present invention employs the following means in order to eliminate the above disadvantages.
In the first aspect of the invention, a casing having an inlet at the top and having an outlet below the inlet, and a center line provided at the inlet of the casing so as to protrude into the casing are inclined with respect to the vertical line. An inlet tube, and a bottomed rotating tube that is concentrically attached to the inlet tube from below and is rotatably fitted so as not to be in sliding contact with the inlet tube, and has a downward opening in the inlet tube The bottomed rotating cylinder is configured to cover or not cover the downward opening depending on the rotation position.
[0005]
[Effects of the Invention]
The invention of claim 1 has the following effects.
Since the bottomed rotating cylinder is rotatable so as not to be in sliding contact with the inlet cylinder, that is, since the bottomed rotating cylinder is not rotatably supported by the inlet cylinder, the bottomed rotating cylinder and the inlet cylinder If the gap is made slightly larger in consideration of the particle size of the granular material, the granular material will be crushed between the bottomed rotating cylinder and the inlet cylinder as the bottomed rotating cylinder rotates. In addition, the bottomed rotating cylinder does not rotate smoothly due to the powder particles entering between the bottomed rotating cylinder and the inlet cylinder.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
In the following, three embodiments of the present invention will be described with reference to the drawings.
In these descriptions, the same members are denoted by the same reference numerals.
[0007]
[First Embodiment of the Invention] (See FIG. 1)
The valve device 1 has a casing 5 having an inlet 3 at the top and an outlet 4 below the inlet 3, and a center line m provided so as to protrude into the casing 5 at the inlet 3 of the casing 5. An inlet cylinder 7 having a circular cross-section inclined with respect to the bottom, and a bottomed rotation that is rotatably fitted to the inlet cylinder 7 so as to be concentric with the inlet cylinder 7 from below and not to be in sliding contact with the inlet cylinder 7 And a tube 9.
Note that the gap between the bottomed rotating cylinder 9 and the inlet cylinder 7 is generally slightly larger in consideration of the particle size (or maximum length) of the granular material.
[0008]
The casing 5 includes a cylindrical main body and a pair of closing plates that close both ends of the main body, but the shape of the casing 5 is arbitrary.
[0009]
A connecting pipe 11 is connected to the upper end of the inlet cylinder 7, and the lower end opening of the inlet cylinder 7 is a downward opening 12. A virtual surface A including the end face of the downward opening 12 is directed downward from a virtual surface B orthogonal to the center line m of the inlet cylinder 7. That is, the virtual surface A is made to face downward from the virtual surface B passing through the lower end of the downward opening 12.
[0010]
The bottomed rotating cylinder 9 has a cylindrical cylindrical main body 14 and a bottom plate 15 provided at the lower end of the cylindrical main body 14. The upper end surface 14 a of the cylindrical main body 14 is positioned on a virtual plane C that is inclined with respect to the center line m of the bottomed rotating cylinder 9.
The bottomed rotary cylinder 9 is configured to be rotated by a rotary actuator 16.
[0011]
With the configuration as described above, the bottomed rotating cylinder 9 is placed at the position indicated by the solid line in FIG. 1, that is, the highest portion of the cylindrical main body 14 is directed downward, and the downward opening 12 is covered so that the particles The body can be prevented from flowing out from the downward opening 12, while the bottomed rotating cylinder 9 is placed at the position indicated by the one-dot chain line in FIG. By directing, it is possible to prevent the downward opening 12 from being covered and the granular material flows out of the downward opening 12.
[0012]
A connecting pipe 17 is connected to the outlet 4.
[0013]
Below are additional reference examples.
[Second Embodiment of the Invention] (See FIG. 2)
The downward opening 12 is constituted by a through hole formed in the lower part of the inlet tube 7. Further, a through hole 20 is formed in the cylindrical main body 14 of the bottomed rotary cylinder 9 so as to overlap the downward opening 12 when the bottomed rotary cylinder 9 is positioned at a predetermined rotational position.
With such a configuration, by allowing the through-hole 20 to face upward, the granular material can be prevented from flowing out from the downward opening 12, while the through-hole 20 overlaps the downward opening 12. As a result, the granular material can flow out from the downward opening 12.
The lower end of the inlet cylinder 7 is located in a virtual plane B orthogonal to the center line m and is closed by the closing plate 21.
[0014]
[Third Embodiment of the Invention] (See FIG. 3)
The downward opening 12 is constituted by a through hole formed in the lower part of the closing plate 21 that closes the lower end opening of the inlet tube 7. A through hole 20 is formed in the bottom plate 15 of the bottomed rotary cylinder 9 so as to overlap the downward opening 12 when the bottomed rotary cylinder 9 is positioned at a predetermined rotational position.
With such a configuration, by allowing the through hole 20 to be positioned above, it is possible to prevent the granular material from flowing out from the downward opening 12, while the through hole 20 overlaps the downward opening 12. By doing so, the granular material can flow out from the downward opening 12.
[0015]
[Modifications]
A description will be given below of modifications and the like.
(1) The granular material includes powder, granular material, fine thin piece, short fiber piece and the like.
(2) A hopper, a transport pipe or the like is connected to the connection pipe 11, and a transport pipe or the like is connected to the connection pipe 17.
(3) The cross-sectional shape of the inlet tube 7 is not limited to a circle, but may be a polygon such as a hexagon. The cross-sectional shape of the cylindrical main body 14 may be a polygon such as a hexagon as long as it does not collide with or interfere with the inlet cylinder 7 during rotation.
[0016]
【The invention's effect】
The present invention has the following effects by the configuration as described above.
According to the first to fourth aspects of the present invention, the bottomed rotating cylinder is rotatable so as not to slide on the inlet cylinder, that is, the bottomed rotating cylinder is rotatably supported by the inlet cylinder. Therefore, if the gap between the bottomed rotating cylinder and the inlet cylinder is made slightly larger in consideration of the particle size of the granular material, the bottomed rotating cylinder and the inlet cylinder The granular material is not crushed in between, and the bottomed rotating cylinder does not rotate smoothly due to the granular material entering between the bottomed rotating cylinder and the inlet cylinder.
