傘状の集塵フード(4)(5)で発生した粉塵を排出し
ていた。In a powder supply device that measures and supplies powder such as chemical substances and drugs in the chemical industry, or powder such as grain flour in the food industry, a screw feeder (
Since the discharge ports (1a) such as 1) are large, it is difficult to cut a rotating plate-shaped cut gate (2) as shown in Figure 6 or a large diameter ball valve (3) as shown in Figure 7. used for movement,
Umbrella-shaped dust collection hoods (4) and (5) were discharging the generated dust.
ここで、板状のカットゲート(2)や大口径のボール弁
(3)を使用する理由は、排出口の口径を絞ってしまう
と、集中した圧力が加わって粉体が固まった状態となり
、流れが悪くなり詰まってしまうためである。The reason for using a plate-shaped cut gate (2) and a large-diameter ball valve (3) is that if the diameter of the discharge port is narrowed, concentrated pressure will be applied and the powder will solidify. This is because the flow becomes poor and it becomes clogged.

上述したように、スクリューフィーダ(1)の大きな排
出口(1a)から口径を絞らないで粉体を排出させると
、排出端の口径が大きいためカット動作時に粉体を正確
な供給量で遮断することができない。As mentioned above, if the powder is discharged from the large discharge port (1a) of the screw feeder (1) without narrowing the diameter, the diameter of the discharge end is large, so the powder will be released during the cutting operation. Unable to shut off the body with the correct amount of supply.

ダの送り力よりも、粉体の重量が大きく作用して流れ量
が大きく変化する状態で排出を行うので、粉塵が多発し
、傘状の集塵フード(4)(5)を被せていても周囲へ
の飛散は免れ得なかった。In addition, the discharge is spread over a large area, and the weight of the powder is greater than the feeding force of the screw feeder, and the flow rate changes greatly. Therefore, a large amount of dust is generated, and an umbrella-shaped dust collection hood is used. Even if (4) and (5) were covered, scattering to the surrounding area could not be avoided.

状の集塵フードとを有することを特徴とする。A powder cutting device provided by the present invention to accurately cut powder and prevent dust from scattering to the surrounding area due to a large amount of dust is a powder feeding device. an air entrainer provided at the cutting port; a cutting ball valve provided at the bottom of the air mixing device and having a smaller diameter than the cutting port; and an umbrella-shaped ball valve fitted around the outer circumference of the discharge conduit of the cutting ball valve It is characterized by having a dust collection hood.

上記粉体切出装置の空気混入器は、粉体供給装置の切出
口から排出される粉体に空気を混入させて大きな流動性
を与える。(2) The air entrainer of the powder cutting device mixes air into the powder discharged from the cutting port of the powder feeding device to give it greater fluidity.
従って切出口から口径を絞ってカット用ボール弁に粉体
をdtFさせても流動は円滑に行われる。Therefore, even if the diameter is narrowed from the cutting port and the powder is dtfed to the cutting ball valve, the powder will flow smoothly.
カット用ボール弁は口径が小さいため粉体の流れのカッ
ト動作は正6′mに行われる。また[]径を絞っζいる
ため粉体供給装置からの粉体圧が増加して、適当な圧力
となるから粉体か細い流れとなって容器に排出されるた
め、発塵が減少する。Since the diameter of the cutting ball valve is small, the cutting operation of the powder flow is performed at a distance of 6'm. Also, since the diameter is narrowed, the pressure of the powder from the powder supply device increases and the pressure reaches an appropriate level, so that the powder is discharged into the container as a thin stream, reducing dust generation.
発塵量が少ないため、集塵フードは粉塵を略完全に集p
xすることができ、周囲への飛散は防止される。Since the amount of dust generated is small, the dust collection hood almost completely collects dust.
x, and scattering to the surroundings is prevented.

When placed on the container (20), it will move to its end due to its own weight. After setting the weight of the powder to be accommodated in the control device (not shown) and pressing the start switch (not shown), one volume n (20) is reduced to 41 volumes by the operation of the cutting arm (35). ). After the weighing container (33) measures the tare weight of the container (20), the screw feeder (j9) rotates and the cutting ball valve (8) opens.

よって円滑に流れる。A compressed air introduction pipe (
10) (10)... Enter the air introduction box (11), and the air hole (12) of the guide (13) (12)...
・Air that has passed through is mixed in. This allows air to enter between each particle of the powder, making the powder extremely fluid. This flow of powder is constricted by the guide (13), flows into the cutting ball valve (8), passes through this, and flows down through the discharge conduit (15) into the container (20). Even if the powder flow is narrowed down, the powder mixed with air will flow smoothly due to the pushing force of the screw feeder (19).

、周囲への飛散はなくなる。The flow into the container is a thin flow due to the small diameter of the discharge conduit (15), and since the diameter is further small, the pressure is uniform compared to the conventional state where the diameter remains large. In other words, since the flow flows in a narrow rectified state, there is extremely little dust generation. Also, the small amount of dust generated by this can be removed from the air vent pipe (16) (16) of the umbrella-shaped dust collection hood (9).
It is almost completely discharged from ... towards the vacuum pump, and there is no longer any scattering to the surroundings.

が可能となる。Next, when the net weight obtained by subtracting the tare weight from the weight being measured by the weighing machine (36) of the weighing container (33) approaches the set value, the rotation speed of the screw feeder (19) is reduced, and when the set value is reached, the net weight is tared. A control device (not shown) rapidly closes the cutting hole valve (Σ3) and stops the screw feeder (19). This allows the container (
20) stops flowing down. Since the discharge conduit (15) is thin, the flow rate after closing the cut hole valve (8) is minute, and the increase in the weight of the powder weighed into the container (20) is minute. Therefore, highly accurate metering and supply is possible.

In this case, powders whose diameter is small in the discharge conduit (15) are rectified, and the correction can be made accurately.
