Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a device for granulating wood chips.

(Technical background) Hinoki is a useful and effective wood, but the sawing process produces a large amount of unusable waste wood. There is no known effective way to use this material, and it is extremely wasteful, as it is incinerated. Moreover, the thinned wood produced in large quantities cannot be used as structural materials because of its thinness, and only small amounts are used as extremely cheap materials such as piles.

These discarded and incinerated waste materials would have extremely high utility value if they could be made into specific shapes and mass-produced at low cost.

SUMMARY OF THE INVENTION The present invention solves these problems and provides a wood chip granulation device that can form a large amount of wood chips into uniform granules.

(Means for Solving the Problems) The wood chip granulating device according to the present invention has the following configuration in order to solve the above problems.

That is, a hopper 12 with an open bottom is provided on the belt surface of the sander belt 10, and a partition plate 14 is provided at the end of the hopper in the direction of movement of the sander belt so that the wood chips in the hopper can flow. conversion device.

(Effect) Describe the effect. As the sander belt 10 rotates, the wood chips in the lower part of the hopper 12 are given a force to move in the right direction in the drawing, which is the direction in which they move, but they are blocked by the partition plate 14 and move upward along the partition plate 14, until the wood chips move upward. Except for the one that returns to the left and rotates at the upper part, it descends from the back of the partition plate 14, and the partition plate 1
4 From the gap at the bottom, it moves to the left, accompanied by the rising wood chips, and moves clockwise. During this complicated movement of the wood chips, the protruding parts of the wood chips are removed by the sander belt 10 from various directions, and the wood chips are granulated in a very short time.

(Embodiments) Below, preferred embodiments embodying the present invention will be described in detail with reference to the drawings.

A wide sander belt 10 with a width of about 30 cm is stretched horizontally and is driven by driving rollers 18 provided parallel to each other on the left and right sides. thunder belt 1
The roughness of 0 is about 200 mesh.

A hopper 12 with an open bottom is provided on a sander belt 10, and the bottom of the hopper 12 and the upper surface of the sander belt 10 are brought close to each other with almost no gap. The hopper 12 has a rectangular housing shape that is long in the left-right direction, and its lower part is tapered. Inside the hopper, there is provided a partition plate 14 whose upper part is inclined to the right by about 20 degrees with respect to the vertical.
The lower end of this partition plate 14 is provided at a distance of, for example, about 10 cm from the sander belt surface.
The upper end of the hopper 12 is fixed to the side walls 20, 20 by support arms 22, 22 at a position approximately the same as the upper end of the hopper 12. The right side of the partition plate 14 is a rectangular plate that is long in the vertical direction, and an inverted triangular gap 24, 24 is formed between the side walls 20, 20, which are tapered toward the top. This complicates the flow pattern of When the direction of rotation of the sander belt 10 is clockwise, the position of the partition plate 14 is from the left side wall 26 to the right side in the figure.
The length from the right side wall 28 to the partition plate 14 is about 2:1.

Reference numeral 30 denotes a rotating stirring blade for preventing large-diameter wood chips (not shown) from floating up and staying there, and for sinking them into other wood chips and lowering them to make the whole uniform.

A suction port 32 of a dust suction device is provided on the sander belt 10 on the right side of the hopper 12 to collect a large amount of sawdust generated.

The shape of the wood chips used as the raw material itself is free, but generally cube-shaped pieces cut into 10 mm squares or less, for example 6 mm squares, can be used.
In this case, granules ranging from cubic shapes with rounded corners to perfectly spherical shapes can be obtained. When cylindrical chips are used as wood chips, particles ranging from cylindrical shapes with rounded corners and the shape of a drum body to perfectly spherical shapes can be obtained.

The thin twigs and parts of Hinoki that are close to the epidermis, which are currently discarded, have growth activity and are rich in aromatic components, so the obtained granules are particularly effective as pillow material to be filled into pillows. This product has been appropriately roughened by sandpaper treatment, and its surface area has increased, so it not only releases aromatic ingredients sufficiently, but also releases new aromatic ingredients when they rub against each other in the pillow. , stabilizes the mind and promotes restful sleep. Furthermore, unlike conventional pillow materials such as buckwheat garland and adzuki beans, it can absorb a large amount of moisture. Therefore, when you sweat at night, the sweat can be absorbed quickly, so you won't feel uncomfortable sleeping.

In addition, the substances contained in Hinoki wood have a hair-nourishing effect, which is effective for alopecia areata, etc., and its moderate hardness provides comfortable stimulation to the head, making it easy to use and eliminating musty smells. It is hygienic as it does not cause any damage.

In another embodiment, a rotating disk-shaped scraping section may be used as the sander belt. A suitable chip flow pattern can be selected by adjusting the rotation speed.

Further, it is possible to employ a continuous manufacturing method in which a part of the hopper is formed into a mesh having a specific mesh and the granulated material is continuously taken out. The granulated product thus obtained has excellent uniformity and can be mixed and used as a plastic filler.

The partition plate can be made rotatable and movable.

(Effects of the Invention) As described above, according to the present invention, granulation of all chips, which is extremely difficult, can be achieved with a simple device without complicated devices or controls, and there is no difficulty in operating the device. The uniformity of the front chips is high, and a large amount of wood chips can be stored at once and processed in a short time.

Furthermore, the only thing that is discharged from the device is sawdust, which is currently being used effectively, and it is very effective in that there is no problem in disposing of it.

The preferred embodiments of the present invention have been described above in detail with reference to the accompanying drawings, but the present invention is not limited to the above-described embodiments, and can be modified in many ways without departing from the spirit of the invention. Of course.
