Field of the Invention The present invention relates to a powder dispersing apparatus, and more particularly, to a method for generating suspended powder required for examining the properties of powder and supplying the suspended powder to a powder measuring instrument or the like. The present invention relates to a powder dispersing apparatus capable of performing the above-mentioned.

のことながら篩を用いて分類することなどはできない。2. Description of the Related Art In recent years, it has been increasingly required to clarify not only the macroscopic properties of a powder as an aggregate but also the microscopic properties of the powder particles themselves.
In order to investigate the microscopic properties of the powder, for example, it is necessary to measure the particle size of each powder particle, the shape of the particles, the charge, and the like. Conventionally, by using a sieve or the like, it was also possible to classify the powder according to the particle size, but recently, the particle size of the powder itself tends to be very small, the particle size is 1 to
Research on particles of about 2 μm or smaller has been actively conducted, but such fine powders cannot be naturally classified using a sieve.

高まっている。[0003] Therefore, in order to measure the particle size of fine powder, instead of using a sieve mesh, a laser or other light beam is applied to one particle, and its reflection, projection or photographed image is taken. A powder measuring device or the like for measuring the particle size of the powder is used, but such a measuring device includes a device capable of completely separating the powder particles one by one, that is, a powder dispersion device. Equipment is required. Therefore, as one means for completely separating the powder particles one by one, there has been a growing demand for an apparatus capable of producing a suspended powder as dust and keeping its concentration constant. I have.

ントに行うことができないという問題点があった。[0004] In order to produce the above-mentioned suspended powder, it is necessary to disperse a small amount of powder in a large amount of gas. In this type of apparatus, a screw feeder or a vibration feeder is generally used as a means for supplying the powder to the powder dispersion apparatus. However, screw feeders and vibratory feeders are structurally large in size, so a large amount of sample powder is required to supply a certain amount of suspended powder, and conversely, if the size is reduced,
There is a problem that the supply of several g to several tens g / hour required for the investigation of the powder cannot be constantly performed.

However, the ejector has a problem that the pulsation is large, a gas flow having a constant concentration cannot be generated, and the dispersion pressure is low, so that the degree of dispersion is insufficient.

Compressed air supplied from the apparatus is mixed with the dry compressed air and a pressure outside the powder dispersing apparatus 10, for example, a closed pressure vessel 11.
The pressure difference from the internal pressure of a powder measuring instrument or the like connected to the discharge port 34 of the cylinder passes through the through-hole 28 opened in the partition plate 27 of the sealed pressure vessel 11 and the outer wall of the suction nozzle 30 and the cylinder 12. The powder reaches the powder 36 stored in the cylinder 12 through the air passage in the gap with the inner wall. Here, as described above, since the cylinder 12 is rotating and rising, the powder 36 is stirred and floated by the screw 40, and the floating powder 36 is further sucked by the suction port 3 of the suction nozzle 30.
The powder-mixed air is carried or dispersed / mixed in the dry compressed air that has reached the second compressed air, and is discharged from the outlet 34 to the outside of the powder dispersing device 10 through the inside of the hollow suction nozzle 30, and is, for example, powdered. Supplied to an anthropometric device.

Even with a small amount of sample powder, floating powder can be generated, and because of pressure feeding due to a pressure difference, the dispersibility of the powder is extremely good. Further, according to the powder dispersing device of the present invention, since there is no pulsation, the powder can always be dispersed and mixed in air at a constant concentration, and the moving speed of the powder storage member is changed. Thereby, the concentration of the suspended powder can be freely set. Further, according to the powder dispersing apparatus of the present invention, the powder is stored in the powder storage member, and the compressed and dried air is supplied, and the powder storage member is simply rotated and raised by the rotating means and the vertically moving means. Since floating powder can be easily generated, not only is the operability excellent, but also there is almost no powder remaining in the powder storage member after use, so there is no need to wash the inside of the equipment and the maintainability is excellent. ing.
