Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a device for dispensing powder. More specifically, the present invention relates to an apparatus used for distributing and charging powder into a plurality of containers, reactors and the like (hereinafter referred to as containers).

[0002]

2. Description of the Related Art When powder is charged into a plurality of containers, it is often the case that the powder is manually charged into each container. The work of putting the powder into the container is a heavy-duty work, and the work environment is often bad such that dust is generated and odor is generated depending on the powder. Therefore, there is much demand for mechanization of the work of putting powder into a container.

When the powder is charged into a plurality of containers, it is necessary to provide a charging device for each container or move the charging device, but this requires an excessive capital investment and is difficult to arrange. However, installation of the device is often difficult. In view of such circumstances, the inventors of the present invention have conducted extensive studies to solve the above-mentioned problems, and as a result, have developed a compact powder dispenser without clogging trouble.

[0004]

That is, according to the present invention, a plurality of discharge ports 10 having a plurality of compressed gas injection nozzles 7 on the inner periphery thereof are provided at the bottom of a cylindrical distribution container 1, and a lower portion of the discharge ports is provided. A non-sliding cut-out valve 3 for opening and closing the discharge port, a chute 5 for guiding powder, and a scraper 2 for scraping powder in a distribution container with a rotating shaft at the center of the bottom. The powder distribution device is characterized by being provided with.

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a diagram showing an outline of a powder distribution device. 2 is a sectional view taken along the line AA of FIG. FIG. 3 is an enlarged view of a compressed gas injection nozzle portion. The powder is charged into the cylindrical powder distribution container 1 from above. In the present invention, the method for charging the powder into the distribution container is not limited, and may be manually performed or a charging device may be used. A discharge port 10 is provided at the bottom of the relay container. Normal,
The number of the discharge ports is 2 to 4, but it is possible to increase the number, but it becomes complicated and the arrangement becomes difficult.

A chute 5 for guiding the powder from the distribution port to the container is provided at the lower part of each discharge port, and passes through this chute to a container (not shown) located ahead of this. The powder is put into.

A non-sliding cut-out valve 3 for opening and closing the discharge port is provided under each discharge port, and sequentially opens and closes to switch the powder feeding destination. A non-sliding cut-out valve is preferably used as the valve for opening and closing the discharge port. This valve moves the valve element upward through the valve shaft by the eccentric mechanism of the actuator, and the valve element is pressed against the valve seat portion like a stop valve to close the discharge port. When the discharge port is opened, the valve element is moved downward by the eccentric mechanism of the actuator until a proper gap is formed from the valve seat surface, and then the valve element is rotated by about 90 ° by the rotational movement of the actuator. For this reason, it is possible to completely seal without powder being caught. Examples of such a valve include OKS4000CF type manufactured by Osaka Kikai Seisakusho Co., Ltd.

A plurality of compressed gas injection nozzles 7 are provided on the inner circumference of each discharge port. In this injection nozzle, powder is compressed on the valve body of the closed discharge port to form a plate shape, which obstructs the discharge of powder. Is. Although the number of injection nozzles depends on the powder to be handled, it is usually 2 to 4 at each discharge port. Usually, the compressed gas is supplied from below the bottom plate of the distribution container through a pipe (not shown) and is ejected from the injection nozzle. Air or nitrogen is usually used as the compressed gas to be sprayed, and the pressure is usually about 2 to 5 kg / cm ² G, although it depends on the powder to be handled.
The injection of the compressed gas is performed before opening the valve, or periodically as necessary. In the case of cohesive or adherent powder, the powder tends to be plate-like on the upper part of the valve body, and this compressed gas injection treatment is effective.

A scraper 2 is provided at the bottom of the distribution container. A rotating shaft is provided in the center of the distribution container, and the scraper blade is rotated by controlled rotation by the cyclo reducer 6, scraping the powder put into the distribution container and dropping the powder from the opened discharge port. . It is preferable that a Teflon sheet is attached to the scraper blade to eliminate the gap between the bottom and the side of the container and wipe the bottom and the side of the container. The shape of the scraper is preferably a swastika shape for scraping the powder.

A predetermined amount of powder is put into a distribution container, scraped by a scraper, dropped from an opened discharge port, and put into a container via a chute. Next, this discharge port is closed, another discharge port is opened, and the powder is sequentially distributed to another container by the same operation. These operations are performed automatically. It should be noted that it is desirable that a shower of air or nitrogen be applied to the peripheral portion of the distribution container where the powder is likely to remain, a non-sliding cut-out valve, etc. so that the adhering powder can be removed. .

[0011]

The device of the present invention has a compact structure,
It is possible to reliably distribute the powder without any clogging trouble.
