Description

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

Prior Art As shown in FIG. 4, the conventional technology is to provide a spiral ridge 13 inside a rotating cylindrical container 11, and as it rotates, fine powder is delivered to a discharge port 1 at one end of the container along the ridge.
It was to be transferred to 2.

Furthermore, Japanese Utility Model Application Publication No. 57-191432 discloses a rotating cylindrical container having a plurality of buckets and baffles circumferentially on the inner wall of the container, the axis of rotation being inclined from the inlet to the outlet, A device is known in which the fine powder supplied from the inlet flows along the slope to the outlet.

Problems to be Solved by the Invention The conventional technique shown in FIG. Although it is possible to transfer a fixed amount at a time, the actual fine powder is
As shown in FIG. 5, as the container rotates, the fine powder 10 in the container repeats states A and B like a seesaw, and advances toward the discharge port 12 without being stirred. If the powder is left in the container for a while, the powder will stick together into larger clumps and become clogged at the bottom, and when the container is rotated, the clumps will often be discharged. There was a problem with the amount becoming unstable.

In addition, in the product disclosed in Japanese Utility Model Application Publication No. 57-191432, the bucket and baffle plates are arranged circumferentially around the axis, so if it was rotated with the axis of rotation horizontal, it would be difficult to simply stir and mix. However, there was a problem in that the fine powder could not be made to flow from the inlet to the outlet using only the bucket and the baffle plate.

Means for Solving the Problems Therefore, the present invention not only stirs fine powder around a horizontal axis of rotation, or not only transports it, but also stirs it while transporting it, even if the supply is interrupted. This is intended to provide a quantitative stirring transfer device for fine powder that can sequentially transfer the powder present in a container and always obtain a stable discharge amount.One end of the almost horizontal axis of rotation is offset toward the inlet side. In a rotating cylindrical container, which rotates while storing fine powder, and discharges the fine powder to the outside from a discharge port provided at the other end, the rotary cylindrical container contains, as the container rotates, the fine powder. A plurality of blades are installed along the rotation axis to scoop up the fine powder and cause a portion to fall in the direction of the discharge port along the rotation axis, and a portion to fall in a direction crossing the rotation axis. It is an object of the present invention to provide a quantitative stirring and transfer device for fine powder, which is characterized in that the fine powder falling in the direction of the discharge port is sequentially arranged so that it can fall onto the blades adjacent to each other in the direction of the discharge port.

Function The fine powder in a rotating cylindrical container installed horizontally tends to be deviated to one side of the rotation axis due to its own weight even when the container rotates, but the blade of the present invention At the same time, scoop the fine powder onto the top surface,
If it is lifted to a certain height and the scooping surface tilts as it rotates, the fine powder will fall again, but some of the fine powder that falls from the blade will directly intersect with the axis of rotation of the container. However, some of the fine powder particles fall onto adjacent blades along the rotation axis in the direction of the discharge port, and some of the fine powder that falls onto the blades is further agitated. The liquid falls onto the blades, is sequentially stirred and transferred toward the discharge port, and finally, a portion of the liquid that falls from the blades that are close to the discharge port is discharged in a fixed amount. Therefore, the fine powder is constantly stirred and transferred at the same time as the container rotates, and even if the supply is interrupted, the fine powder remaining in the container will be sequentially sent toward the outlet, resulting in a stable powder. This results in a discharge amount of .

Embodiments The present invention will be described in detail with reference to the embodiments shown below. Reference numeral 1 denotes a cylindrical 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 after receiving the supply of fine powder. Inside the container 1, there are a plurality of blades 3a, 3b, 3c along the rotation axis direction.
...is installed protrudingly. In the embodiment, the blades are provided in two rows with the rotation axis 0 in between, but even in one row,
Even with three or more rows, settings can be made 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 the blade surface between adjacent blades in the rotating direction, and in principle, the blade faces from the back of the container 1 toward the discharge port 2. , for example, the blade 3a is stronger than the blade 3b.
b is set so that the blade surface of the blade farther from the discharge port 2 is higher than that of the blade 3c. 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 sloped in a downward direction from the back of the container toward the discharge port 2 with respect to the blade surface of the adjacent blade. It is constructed so that a part of the fine powder taken up can fall toward 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 step of the blade surface of each blade depend on the number of blade rows in the container 1. Various selections should be made taking into account the relationship.

In the embodiment configured as described above, when the rotating cylindrical container 1 rotates around the substantially horizontal rotation axis 0, the fine powder 10 is scooped up by the blades 3 as in the state A, as shown in FIG. When the blade 3 is 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. 3, a part of the fine powder 10 falls onto the adjacent blades in the direction of the discharge port. The remaining part 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, a part of it is sequentially conveyed by the blade toward the discharge port, and is discharged along the axis. A certain amount of fine powder falling in the direction of the outlet is discharged from the discharge port 2. Therefore, even if the supply of fine powder from the container supply port is interrupted, the fine powder present in the container is sequentially transferred as is and reaches the discharge port, so that a stable discharge operation is always possible.

Effects As described above, according to the quantitative agitation and transfer device for fine powder according to the present invention, the apparatus rotates with the fine powder deviated to the inlet at one end of the substantially horizontal axis of rotation, and the fine powder is transferred to the other end. In the rotating cylindrical container, the fine powder is scooped into the rotating cylindrical container as the container rotates, and a portion is placed along the axis of rotation. A plurality of blades that fall in the direction of the discharge port and some of which fall in a direction intersecting the rotation axis are arranged so that the fine particles falling in the direction of the discharge port along the rotation axis are adjacent to each other in the direction of the discharge port. Since the blades according to the present invention have a structure in which they are arranged in sequence so that they can fall upward, as the blades rotate, some of the fine powder is agitated in a direction crossing the axis of rotation of the container, and at the same time, some of the fine powder is stirred as it is. The particles fall onto adjacent blades in the direction of the discharge port in the direction of the rotation axis, and some of the fine powder that has fallen onto the blades further falls onto the blades and is sequentially transferred while stirring in the direction of the discharge port. Ultimately, a portion of the powder that falls from the vane closest to the discharge port will be dispensed in a fixed amount, so even if the supply of fine powder from the container supply port is temporarily or permanently interrupted. Also, the fine powder in the container is constantly stirred and transferred at the same time as the container rotates, which has the effect of providing a stable amount of powder to be discharged.
