【発明の詳細な説明】 〔産業上の利用分野〕 本発明は粉粒体の混合方法とその装置に係る。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a method for mixing powder and granules and an apparatus therefor.

く、混合時間も比較的長く、更にバッチ式が多く、従っ
て作業工数も多く、特にフロウライン上においては大き
なネックとなっていた。The conventional method for mixing powder and granules is roughly classified into the following two types. One is a method of mixing powder and granules by rotating a rotary blade in a container (a ribbon blender, etc.), and the other is to rotate the container itself and force the powder and granules in it to gravity. The method is to move up and down and mix (rotary mixer, etc.). This is a method of mechanically mixing the powder and granules. Therefore, it cannot be said to be sufficient when the mixing ratio is a very small value or when microscopic dispersion is required. In addition, the volume of the container is relatively large, the mixing time is relatively long, and there are many batch systems. Therefore, the number of man-hours required is large, which is a big bottleneck especially on the flow line.
最近はハイテクの急伸展に伴い、粉粒体の微量値比混合
とミクロ的均一分散などの需要が急増してきた。しかし
上述の如く、従来の機械的方法による混合においては、
それらの要求を十分満すことは困難であった。Recently, with the rapid growth of high-tech, the demands for small value ratio mixing of powder and granules and microscopic uniform dispersion have increased rapidly. However, as mentioned above, in conventional mechanical mixing,
It was difficult to meet those demands sufficiently.
本発明の動機は、粉粒体の微量値比混合とミクロ的均一
分散とを簡易かつ小規模、短時間に行なう方法及び装置
を提供することであった。The motivation of the present invention was to provide a method and a device for carrying out a minute value ratio mixing and microscopic uniform dispersion of powder and granules easily, in a small scale and in a short time.
上述の如く、従来の機械的混合手段をもってしては限度
があるので、従来のものとは全く別な観点に立って混合
を行なう方法を模索した。即ち粉粒体をエアスプレイ
し、その煙霧状態の下において混合することに着目し、
実験を行ない、所期の成果を得ることができたのであ
る。As described above, there is a limit to the conventional mechanical mixing means, so a method for mixing was searched for from a viewpoint completely different from the conventional one. That is, pay attention to air spraying the powder and granules and mixing them under the haze condition,
The experiment was carried out and the desired result was obtained.
１）先ず本発明の方法について説明する。第１図参照さ
れたい。半密閉型のホッパ状容器１の中で、異種のＡ粉

互いに衝突させ、それによって乱流を起こさせる。それ
らのスプレイは煙霧体であるので、煙霧体の乱流によっ
て異種の粉粒子は入り混る。1) First, the method of the present invention will be described. See FIG. In the semi-closed hopper-shaped container 1, different kinds of A powder and B powder are pressure-fed by an air ejector for powder and granular material, and the powder is sprayed from respective air spray nozzles 2, 3. Then, the head portions of the spray patterns As and Bs collide with each other, thereby causing turbulence. Since those sprays are fumes, the turbulent flow of the fumes causes the mixing of different powder particles.
元来、煙霧体における粉粒体の充実密度（容積比重）は
極めて小で、従来の機械的混合において用いられた容器
内の粉粒体のそれに比べると数千分ないし、数万分の一
という超低密度である。このように粉粒子の分散間隔の
極めて大きい状態の下で、粉粒子が互いに行き交うので
これら異種の粉粒子は相互の間に容易に入り込み、入り
混って、均一的な分散が容易にかつ短時間に行われるの
である。Originally, the solid density (volume specific gravity) of the particles in the fumes is extremely small, and is several thousand to one tenth of that of the particles in the container used in conventional mechanical mixing. That is the ultra-low density. Under such a condition that the dispersion intervals of the powder particles are extremely large, the powder particles cross each other, so these different kinds of powder particles easily enter and intermingle with each other, and uniform dispersion is easy and short. It is done in time.
このようにして得られた煙霧体の混合体を上記ホッパ状
容器１から引出して、別装置の気粉分離装置によって気
体と粉粒体とを分離し、混合粉粒体を得るのである。The mixture of the fumes thus obtained is drawn out from the hopper-shaped container 1, and the gas and the granules are separated by a gas-powder separating device, which is a separate device, to obtain a mixed powder-granule.

ことが望ましい。There are various spray patterns to be caused to collide with each other, but there are four main patterns. First, it has a conical shape. This is a generally used pattern as seen in FIG. 4, and in this case, the skirt has a wide hem, and dispersion and mixing are performed in a wide zone. Next, as shown in FIG. 5, the shape is an elongated conical shape. In this case, the collision force at the leading portion of the pattern becomes larger, the diffusion flow spreads in the full angle direction, and wider dispersion is performed. In the case of the third fan shape, as shown in FIG. 6, the cross section at the leading end has a convex lens shape, and when they collide with each other, the diffusive flow is divided into left and right. In the final cross-shaped pattern, as shown in FIG. 7, in addition to the above-mentioned left and right, the diffusive flow is divided up and down. Although all of these have special losses, it is desirable to select them appropriately in consideration of the conditions such as the specific gravity of the powder and granules, the mixing ratio, the pressure of the pressurized gas and the like.

Please refer to FIG. 3 and FIG. 6, air spray nozzle
The intersection O of the extension lines of 7,8 (or 11,12,13,14) is the center of the generally circular hopper-shaped container 5 (or 10). That is, at the center, these sprays are relatively impinged under substantially the same phase.

プレイすることが望ましいのである。In the collision type mixing method, it is desirable that the states of the sprays that collide with each other be very similar. Therefore, it is desirable to use two air spray nozzles in the case of two types of powder and granules, and three or more in the case of three types. However, if the mixing ratio is not uniform and the difference is large, premix a small amount into a large amount and then divide it into two or three large ...
It is desirable to spray with two or three air spray nozzles.

われるのである。The operation of the device according to the present invention in the above item 2) will be described. See also Figure 8. The pressurized gas CA adjusted to each required pressure and flow rate is supplied from the pressurized gas generation device 32, through the respective control devices 31A, 31B, etc., through the gas supply pipes 30A, 30B, and the air ejector 28A. , 28B. Then, at the outlets of the air ejection holes 29A, 29B, the powder or granular material supplied to the surroundings is sucked, transported by gas, and ejected from the spray nozzles 25A, 25B attached to the tips thereof. And those spray As and Bs concentrate on a central part and collide with each other. It is desirable that the spray patterns have the same shape, and due to their collision, the heads of both of the sprays (fume bodies) As, Bs, etc. collide with each other, reflect, or diffuse, and mix with each other, causing turbulence. Wake up. Due to the turbulent flow of these fumes, these different types of powder particles are dispersed and mixed. That is, the fumes are mixed.

て適切なものが選択される。There are four types of spray patterns as described in 1) above, but all of these are mixing conditions, that is, the properties of the particles in the granular material, such as specific gravity, size, shape, and mixing ratio. An appropriate one is selected according to the speed of the jet flow, the jet amount, and the like.

る。In this way, the hopper-shaped container 21 is filled with the mixture of the powder particles and the gas which are effectively dispersed and uniformly mixed.
Then, the discharge port 23 provided at the bottom of the hopper-shaped container 21.
In the part, the exhaust device 41 provided at the end of the pipe
As a result, a negative pressure is applied, whereby the gas-powder mixture is transported from the discharge port 23 through the discharge pipe 37 connected thereto to the gas-powder separation device 40, where Air dust separation is performed. The back filter 42 is shown in the figure, but in this case, the air-dust mixture APAB is the same as the back filter 42.
42 parts were reached by pneumatic transportation, and powder PAB was backed up.
Stay on the 42nd side. Only the gas A passes through the back filter 42, enters the inside thereof, is sucked by the exhaust device 41, and is discharged to the outside. That is, the mixed powder and granules separated from the air and retained on the surface of the back filter 42 are removed by the vibration applied to the back filter 42 and collected in the lower accumulation box 35.
