Abstract

PURPOSE:To always stably secure an emitting amount by simultaneously performing transfer and stirring, by arranging a plurality of blades so as to allow a fine particulate powder falling to a rotary axial direction to fall on blades mutually adjacent in an emitting port direction. CONSTITUTION:When a rotary cylindrical container 1 is rotated around a rotary axis O, a fine particulate powder 10 is scooped up by blades 3 and upwardly lifted with rotation and fallen from the blades 3 when the blades 3 and inclined. Because the blades 3 are inclined to the axial direction at this time, a part of the fine particulate powder 10 is fallen on blades mutually adjacent in an emitting port direction. The remainder is again scooped up by the blades at the almost same position and, by repeating this operation, the fine particulate powder 10 is stirred many times and a part thereof is simultaneously carried by the blades and a definite amount of the fine particulate powder falling to the axial direction is emitted from an emitting port 2.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is designed to store fine powder in a rotating cylindrical container and to discharge the fine powder at a constant rate from a discharge port provided at one end of the container as the container rotates. The present invention relates to a quantitative stirring and transfer device for finely divided powder.

Conventional technology In the conventional technology, a spiral ridge 13 is provided inside a rotating cylindrical container 1, as shown in FIG. It was to be transferred to 12th.

Problems to be Solved by the Invention Conventional technology is based on the technical idea of transferring a fixed amount of fine powder to be discharged along a convex line, and theoretically it is possible to transfer a fixed amount of fine powder to the discharge port at a time. Therefore, ◆, the actual fine powder is 10 fine powder in the container as shown in Figure 5.
As the container rotates, it moves forward in the direction of the discharge port 12 without being stirred, repeating the state and state B like a seesaw, so if it is left in the container for a while,
The problem is that the powder sticks together into larger lumps and gets stuck towards the bottom, and when the container is rotated, the powder is often dispensed as a lump, and if the container is not shaken well before rotating, the amount dispensed becomes unstable. was there.

Means for Solving the Problems Therefore, the present invention aims to provide a quantitative agitation and transfer device for fine powder, which not only transfers fine powder, but also stirs it as it is transferred, and is capable of always obtaining a stable discharge amount. In a rotating cylindrical container which is configured to rotate while accommodating fine-grained powder with an offset to one side of the axis of rotation, and to discharge the fine-grained powder to the outside from a discharge port provided at one end, the rotating cylindrical container A plurality of blades are installed in the container, which scoop up the fine powder as the container rotates, and cause a portion to fall in the direction of the rotation axis and a portion to fall in a direction crossing the rotation axis. It is characterized by a configuration in which the fine powder particles falling in the direction of the center are arranged so that they can fall onto the blades adjacent to each other in the direction of the discharge port.

Even when the container rotates, the fine powder inside the rotating cylindrical container tends to deviate to one side of the rotation axis due to its own weight.
The blade of the present invention scoops up fine powder onto its upper surface as it rotates, lifts it up to a certain height, and when the scooping surface tilts as it rotates, it drops the fine powder again. A part of the fine powder that falls from the container directly crosses the rotation axis of the container and remains in a fixed position and is stirred, but a part falls onto the blades adjacent to the discharge port in the direction of the rotation axis. A part of the fine powder that fell onto the blade further falls onto the next blade, and is transferred while being stirred in the direction of the discharge port, and finally the part of the fine powder that fell from the blade closest to the discharge port is A fixed amount of the liquid will be dispensed. Therefore, the fine powder is constantly stirred and transferred at the same time as the container rotates, and a stable amount of powder can be discharged.

EXAMPLES The present invention will be described in detail with reference to the examples shown below. Reference numeral 1 denotes a rotating cylindrical container, which is configured to rotate while maintaining a substantially horizontal position with the axis of the cylinder as the rotation axis 0. It has been done. A discharge port 2 is provided at one end of the container 1, and the other end is closed. In the container 1, a plurality of blades 3a, 3b, 3c, . In the embodiment, the blades are arranged in two rows with the rotation axis O in between, but they can be set in a negative row, three rows or more depending on the application situation such as the discharge amount and the width of the blade surface. . As shown in FIGS. 1 and 3, each blade has a step on its surface between adjacent blades in the direction of rotation, and as a general rule, from the back of the container 1 toward the discharge port 2. ,
For example, the blades 3a are set higher than the blades 3b, the blades 3b are set higher than the blades 3C, and the blades farther from the discharge port 2 are set higher. However, for example, it is also possible to adjust the discharge amount by setting the blade surface of every second or third blade closer to the discharge port 2 higher. In addition, as shown in Figure 3, the blade surface of each blade is inclined in the direction downward from the back of the container toward the discharge port 2 relative to the blade surface of the adjacent blade, so that the blade surface can be used for scooping. The structure is such that a part of the fine powder particles can fall in the direction of the discharge port. The inclination angle of the blade surface can be set in consideration of the properties of the fine powder, the area of the blade surface, etc. in order to ensure a constant discharge amount.

In addition, settings such as the size, inclination angle, and level difference of the blade surface of each blade depend on the number of blade rows in the container l, for example.
Various selections should be made in consideration of the relationship between the mutual agitation and transfer effects between the first and second rows of blades.

In the embodiment configured as described above, when the rotating cylindrical container 1 rotates around the rotation axis O, the fine powder 10 is scooped out by the root 3 as in the state A, as shown in FIG. ,
When the blade 3 is lifted upward as it rotates and tilted downward, it will fall from the blade 3 as shown in state B. At this time, since the blades 3 are inclined in the axial direction (the direction of the discharge port 2) as shown in FIG. is scooped up again by the same blade at approximately the same position, and by repeating this process, the fine powder is stirred many times and at the same time some of it is carried to the blade.
A certain amount of fine powder falling in the axial direction is discharged from the discharge port 2.

Effects As mentioned above, even when the container rotates, the fine powder in the conventional rotating cylindrical container tends to deviate to one side of the rotation axis due to its own weight, and is transferred without being stirred. In contrast, the blade of the present invention scoops fine powder onto its upper surface as it rotates, whereas the blade of the present invention scoops fine powder onto its upper surface as it rotates.
When lifted to a certain height and the scooping surface tilts as it rotates, the fine powder is dropped again, and some of the fine powder that falls from the blade continues to flow in a direction that intersects with the axis of rotation of the container. It stays in a fixed position and is stirred, but some of it falls onto adjacent blades in the direction of the discharge port in the direction of the rotation axis, and some of the fine powder that fell onto that blade further falls onto the next blade. The fine powder is then transferred while being stirred in the direction of the discharge port, and finally, a portion of the powder that falls from the blade closest to the discharge port is discharged in a fixed amount.Therefore, the fine powder is constantly stirred as the container rotates. This has the effect of providing a stable amount of powder to be discharged.
