Description

DETAILED DESCRIPTION OF THE INVENTION The present invention vibrates a container having a U-shaped cross section with a removable top cover, and this vibration puts the powder inside the container in a kind of floating rotation state for drying and various other purposes. This invention relates to a powder processing device that performs reactions and the like.

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 device vibrates a cylindrical container supported by an elastic body such as a spring using a vibration source such as an eccentric weight, and the powder in the cylindrical container is brought into a kind of floating rotation state by this vibration. In this state, a heating medium is circulated through a jacket provided around the cylindrical container to carry out processes such as drying and reaction, and the present inventor has already provided the base device (Patent No. 104). Spot No. 26). However, in such conventional devices, the cylindrical container incorporated in the device is a long-bodied cylindrical container installed substantially horizontally with removable covers attached to both sides, and therefore, the diameter of the cylindrical container is particularly large. If the size is small, the amount of powder that is scattered along with the steam generated from the powder during processing and exhaust gases such as carrier gas introduced to increase processing efficiency cannot be ignored, and for this reason, a separate dust collector is installed. In addition, it is extremely difficult to completely sterilize and clean the inside of the cylindrical container, which is required when the cylindrical container is manufactured with an internal finish (e.g., buffed) or when the powder is a pharmaceutical product. There are drawbacks. The present invention provides an improved powder processing apparatus that eliminates the above-mentioned drawbacks of the secondary structure, and its purpose is to provide an improved powder processing apparatus that eliminates the above-mentioned disadvantages of the secondary structure. The U-shape increases the internal space ratio and height to prevent powder from entraining and scattering, and a removable top cover is attached to the top of the container, which has a U-shaped cross section. The purpose is to facilitate finishing work on the interior and various types of maintenance work.

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

FIG. 1 is a side (partially cut away) view illustrating a conventional processing apparatus, and FIG. 2 is a sectional view of a main part showing a cylindrical container in the processing apparatus of FIG. The processing device 11 includes a powder inlet 41 in a substantially horizontally installed long-body cylindrical container 31, which has covers 21a and 21b removably screwed to flanges on both sides.
a, an outlet 41b, and an exhaust port 41c for discharging steam generated from the powder, and a jacket 51 for flowing a heat medium for heating or cooling the powder is provided around the powder.
The cylindrical container 31 equipped with the vibration source 61 is supported by springs 71a and 71M which are elastic bodies, and while the cylindrical container 31 is vibrated by the vibration source 61,
A heating medium is flowed through the jacket 51, and the powder that is continuously introduced from the inlet 41a is placed in a kind of floating rotation state in the cylindrical container 31, where it undergoes processing such as drying and reaction, and the processed powder is obtained from the outlet 41b. It is. However, such conventional devices are difficult to use, especially when the diameter of the cylindrical container is small (for example, when the diameter is 5.
(less than 0 ship), there are many disadvantages as mentioned above.

FIG. 3 is a side view (partially cut away) showing an embodiment of the present invention;
FIG. 4 is a sectional view of a main part of the container in the embodiment of FIG. 3. The processing device according to the present invention includes a powder discharge port 42.
A long vessel 32 with a U-shaped cross section and a perforated section b is surrounded by a jacket 52 through which a heat medium flows, and a top cover 22a is removably screwed to the upper flange of the jacket 52. Powder inlet 42 in cover 22a
a and an exhaust port 42c for discharging steam generated from the powder, and the container 32 provided with the vibration source 62 is installed substantially horizontally while being supported by springs 72a and 72b which are elastic bodies. , the container 32 is connected to the vibration source 62
At the same time, a heating medium is passed through the jacket 52, and the powder that is continuously introduced from the inlet 42a is placed in a kind of floating rotation state in the container 32, where it is subjected to processes such as drying and reaction, and the processed powder is transferred to the outlet. 42b. According to the present invention having such a structure, even if the container is relatively narrow, since the long container is formed to have a U-shaped cross section, the internal space ratio and space height can be increased. Entrainment and scattering of powder as described above can be prevented.

Moreover, since the top cover attached to the entire upper surface of the container is removable, the above-mentioned finishing work and various maintenance operations on the inside of the container can be easily performed. FIGS. 5 and 6 are sectional views of main parts of containers according to other embodiments of the present invention.

In the case shown in FIG. 5, the container 33 having a U-shaped cross section is not provided with a jacket, and a top cover 23a is removably screwed to the upper flange of the container 33, and an electric heating panel is provided inside the top cover 23a. 83 is installed.
In the case shown in FIG. 6, a jacket 54 is provided on a container 34 having a U-shaped cross section, and a removably slightly curved top cover 24a is screwed onto the flange at the top of the jacket 54, and is attached to the inside of the top cover 24a. An electric heating panel 84 is attached along the line. In both cases, the top cover is removable, so an electric heating panel like the one shown in the figure, which can be easily attached to the inside of the top cover, enables high-temperature processing that is difficult to achieve with steam, which is normally used as a heating medium for the jacket. For example, high-temperature treatment at about 200 to 300° C.) can be carried out easily and safely. FIG. 7 is a side (partially cut away) view showing still another embodiment of the present invention.

The processing device 15 according to the present invention includes a long container 35 with a U-shaped cross section and a powder discharge port 45b, and a jacket 55 for flowing a heat medium around the container 35, which is detachable from an upper flange. A top cover 25a is screwed onto the top cover 25a, and the container 35 including the vibration source 65 is repositioned substantially horizontally while being supported by springs 75a and 75b, which are elastic bodies. In this case, the top cover 25a is provided with an inlet 45a for the powder and an exhaust port 45c for discharging steam generated from the powder, and an electric heating panel 85 is attached to the inside of the inlet 45a for the powder. 4 rope feathers 95a, 95b, 9 inside
5c and 95b are inserted. In the drawing, such a frame blade is supported by the top cover 25a, but a gate may be assembled above the processing device 15, and the rope float line may be supported by the gate. Since the upper surface cover is removable, it is easy to insert the foot floating blade from the upper surface cover as shown in the figure, and the clear azure blade allows the granules ( This can powerfully break up lump-like particles that occur during the processing of the powder, especially those that occur in relation to the moisture content of the powder.
