Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a powder processing apparatus, more specifically, vibrates a cylindrical body so that the powder is in a kind of floating rotation state inside a plurality of powder processing cylinders within the cylindrical body. When moving, the powder is indirectly affected by the heat medium supplied into the cylinder through the peripheral wall of the powder processing cylinder, thereby performing treatments such as drying, cooling, and various other reactions. The present invention relates to an efficient powder processing device.

BACKGROUND OF THE INVENTION Powder processing equipment using a vibration method is widely used in factories that manufacture powdered pharmaceuticals, chemical products, and the like.

This type of processing equipment vibrates a container supported by an elastic body such as a spring using a vibration source such as an eccentric weight, and the powder in the container is brought into a kind of floating rotation state by this vibration. In this system, a heat medium is circulated through a jacket surrounding the container to perform drying, cooling, and various other reactions, and the present inventor has already provided the basic device (patented). Law No. 1046826). However, in such conventional devices, the powder flows only in one direction in the aforementioned container built into the device in a so-called one-pass method, and the heating medium directly and effectively acts on the powder in the container. It is only the part of the container peripheral wall that comes into contact with the powder. When a roughly circular rotational motion is applied to powder by normal vibration, the powder behaves in the same circular direction, but as the diameter of the container increases as the throughput increases, the inside of the container increases. When the thickness of the powder layer increases and reaches a certain level, the influence of the peripheral wall of the container on the powder in the center decreases, and as a result, processes such as drying, cooling, and various reactions become inefficient. It has the disadvantage of being a target. The present invention provides an improved powder processing apparatus that eliminates the above-mentioned conventional drawbacks, and the object thereof is to provide a powder processing apparatus that handles a plurality of powders having a relatively small diameter in one cylinder provided with a vibration generation source. By providing a processing cylinder and allowing the heat medium supplied into the cylinder to affect the powder floating and rotating in the powder processing cylinder via the peripheral wall surface of the powder processing cylinder, On the one hand, the heat transfer area is increased, and on the other hand, the layer height of the powder in the powder processing cylinder is lowered to improve the processing efficiency of the powder.

Hereinafter, the configuration of the present invention will be explained in detail based on the drawings.

FIG. 1 is a side (partially cross-sectional) view illustrating a conventional processing apparatus, and FIG. 2 is an enlarged vertical cross-sectional schematic view showing the inside of a cylindrical container in the processing apparatus of FIG.

The cylindrical container 31 is supported by springs 51a and 51b, which are elastic bodies, and while the cylindrical container 31 is vibrated by a vibration source 31b, a heat medium is caused to flow through the jacket 31a, and the inlet 41a
Powder A, which is continuously introduced from the cylindrical container 31, is placed in a kind of floating rotation state and subjected to treatments such as drying and reaction, and the processed powder is obtained from the outlet 41b. However, such conventional devices have the drawbacks mentioned above.

The processing device 12 according to the present invention includes a substantially horizontally installed long cylinder body 3 to which an inlet 32a and an outlet 32b of a heat medium are connected.
Support plates 22a and 22b that seal the inside of the cylinder 32 are fixed to the flanges on both sides of the cylinder 32 by screws or welding, and five powder processing cylinders 62a are arranged between the support plates 22a and 22b. -62e are mounted and fixed, and these powder processing cylinders 62a-62e each have powder inlets 72a-72e and outlets 74a-74e as shown by arrows in the figure.
and exhaust ports 73a to 73e for steam, etc. generated from the powder.
are connected to each other, and the cylindrical body 32 provided with the vibration generating source 32e is supported by springs 52a and 52b, which are elastic bodies. Then, the cylindrical body 32 is connected to the vibration source 3
2c, while a heating medium is passed between the powder processing cylinders 62a to 62e and the cylinder body 32 from the inlet 32a to the outlet 32b, and the powder continuously introduced from the inlets 72a to 72e is heated. When the inside of the body processing cylinders 62a to 62e becomes a kind of floating rotation state and is swept away according to the amount of input,
The powder A2 is subjected to treatments such as drying, cooling, and various other reactions, and the treated powder is obtained from the outlets 74a to 74e. The number of powder processing cylinders is arbitrary as long as it is plural;
As shown in FIG. 5, which is an enlarged vertical cross-sectional view of the interior of the cylinder in another embodiment of the present invention, a cylinder 33 is shown in FIG.
It is also possible to fix the seven powder processing cylinders 63a to 63g in the rhombic frame as described above, and process powder in each of these powder processing cylinders.

FIG. 6 is a partially omitted side (partially sectional) view showing still another embodiment of the present invention.

The embodiment shown in FIG. 3 is a case in which the powder processing cylinders 62a to 62e are simply arranged side by side without being interconnected, but the embodiment shown in FIG. Processing tube 64a
, 64b are connected at their ends by a lotus port 84, and the powder continuously introduced from the inlet 75a is in a kind of floating rotation state as described above, and the inside of the powder processing cylinder 64a is moved to the left in the figure. The powder is swept in the direction, reaches a weir plate 94a protruding from the lotus passage □ 84 to the inside of the center side, overflows this weir plate 94a and is thrown into the powder processing cylinder 64b through the lotus passage port 84, and then this The powder is swept inside the powder processing cylinder 64b to the right in the figure, reaches a similarly protruding weir plate 94b, overflows this weir plate 94b, and is discharged from the outlet 75b. In this embodiment, a cylinder 34, an inlet 34a and an outlet 34b for a heat medium, support plates 24a and 24b, exhaust ports 76a and 76b for steam generated from powder, a vibration source 34c, and springs 54a and 54b that are elastic bodies The interrelationships of other components are the same as in the embodiment shown in FIG. The number of communicating powder processing cylinders is arbitrary; for example, seven powder processing cylinders 6 in the embodiment shown in FIG.
All of 3a to 63g can be connected in the same way, so that the powder A3 can be successively swept away in opposite directions through these seven powder processing cylinders.

Although the present invention is not limited to the illustrated embodiments, such as the shape of the cylinder, the shape of the powder processing cylinder, and the means for fixing each component, the shape of the powder processing cylinder is It is preferable to have a curved or inclined shape that does not make it difficult for the powder to float and rotate.

According to the present invention described above, since a plurality of powder processing cylinders having a relatively small diameter are provided in one cylinder,
For example, when drying powder, a sufficient heat transfer area required depending on the moisture content of the powder before treatment can be easily secured. Moreover, the direction of vibration of the cylinder in the present invention is not an oblique direction that provides a driving force for moving the powder in conventional vibrating compactors, etc., but mostly only in a substantially circular radial direction, which makes it difficult to process powder. Because the powder in the cylinder is fluidized in a kind of floating rotation state due to the vibration, the movement of the powder from the inlet to the outlet can be easily determined by the amount of powder input from the inlet. can. therefore,
Depending on the properties and amount of powder to be processed, a single large-diameter container can be created by appropriately selecting powder processing cylinders that provide the most appropriate powder layer height and using the necessary number of them. Compared to the conventional devices incorporated in the system, it is possible to dry, cool, and perform various reactions on powder much more efficiently.
