本発明は、粉体、流体用サンプラに関し、さらに詳しく
は、大晴の粉体または波体の一部を輸送中にサンプリン
グし、全輸送物の物性を代表するサンプルを得るための
装置に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a sampler for powders and fluids, and more specifically, it samples a part of large powder or corrugated material during transportation, and samples the entire transportation. This invention relates to an apparatus for obtaining samples representative of the physical properties of objects.
人７．；の輸送中の粉体または流体（以下被測定物と称
する）より代表サンプルを正確にサンプリングするには
、被測定物の単位時間ちりの輸送量に比例したサンプリ
ング闇を輸送量の数七分の１ないし数丁分の１の縮分比
で採取しなければならない。Person 7. In order to accurately sample a representative sample from a powder or fluid (hereinafter referred to as the object to be measured) being transported, it is necessary to set the sampling density proportional to the amount of dust transported per unit time of the object to be measured to several sevens times the amount of transported dust. It must be sampled at a reduction ratio of one to several parts of
・般的に単位時間の輸送！翳が大きければこれに比例し
てサンプリングにを多くする必要があり、これに伴い被
測定物の物性解析のための作業量が増えるため、縮分比
は大きくせざるを得ない、縮分比が大きくなる程、縮分
過程でのエラーにより、被測定物の物性とサンプリング
された物性の解析値に偏差が生ずる可ス敞性が大きくな
る。・Generally unit time transportation! If the shadow is large, it is necessary to increase sampling in proportion to this, and this increases the amount of work required to analyze the physical properties of the measured object, so the reduction ratio must be increased. The larger the value, the greater the possibility that deviations will occur between the physical properties of the object to be measured and the analytical values of the sampled physical properties due to errors in the reduction process.
また間欠採取によってサンプリング間隔をあけて断続的
に採取する従来の装置では、被測定物の物性の時間的変
動が多い場合、採取間隔が大きいと誤差が大さく、採取
間隔を小さくする程サンプリング精度がにがるが、採取
猜も比例して増加するためやはり縮分操作が多くなる。In addition, with conventional equipment that takes samples intermittently at sampling intervals, if the physical properties of the object to be measured vary greatly over time, the longer the sampling interval is, the larger the error will be, and the smaller the sampling interval is, the greater the sampling accuracy will be. However, since the number of mushrooms to be collected also increases proportionally, the number of reduction operations will increase.
被測定物の流量が時間的に変動する時はサンプリングの
騒もその変動量に比例したサンプル晴とすることが望ま
しいが、この目的を達成するためには、何らかの方法で
被測定物の流量を検出し。When the flow rate of the object to be measured fluctuates over time, it is desirable that the sampling noise be proportional to the amount of variation. Detect.
その情報によって、サンプリング場を増減できるような
高度なサンプラを備えなければならない。Sophisticated samplers must be equipped that can increase or decrease the sampling field based on that information.

制御することによって、中位時間当りの通過量に見合っ
たサンプラ２４の回転数が得られるため、サンプリング
される試料２６も被測定物の流量に比例する。For example, the conventional sampler shown in FIG. 8 samples a sample by rotating a rotary packet 23 that scoops up a sample from a transport path 25 of the object to be measured using a rotary drive type 2222. By detecting the amount of passage (Δ0/T) with the flowmeter 21, converting the information into signals such as current and voltage, and controlling the rotation speed of the rotary drive device 22, the amount of passage per medium time can be calculated. Since the rotation speed of the sampler 24 can be obtained in accordance with the flow rate of the sample 26, the sample 26 to be sampled is also proportional to the flow rate of the object to be measured.

能のサンプラを提供することをｒＩ的とする。The present invention is capable of rationally contracting the flow 76 directly and continuously from the flow path of the object to be measured in accordance with the flow rate of the object to be measured, without having a complicated device such as a measuring device or a rotation speed control device coupled thereto. A separate sample can be taken. Our goal is to provide a simple and high-performance sampler.

A flow path 6 to be measured is formed such that the object 5 to be measured passes through a portion of the blade Ilj 4 in the axial direction. Since the axial flow blade 3 has a fixed pitch angle with respect to the axis, the object to be measured hits the blade 2 and slides on the surface of the blade 2, thereby imparting rotational force to the impeller 4. ,

FIG. 1(b) shows that due to the rotation of the impeller 4, the object to be measured 5 flows down the sample collection blade 7.
A state in which the flow F flows in the direction of inclination of the sample collection blade 7 and flows through the sample collection channel 8 is shown. At this time, the flow object becomes sample 9.

みがサンプル採取流路８に誘導されサンプル９となる。The rotary vane 4 is divided into 6 to 8 parts in the circumferential direction, and each part is divided into 1
Each section is equipped with axial flow blades 3 having an inclination of 6 right angles = 15 to 45 degrees, one-sixth of which (in the case of 6 divisions).
Or the blade of the 1/8th division part is blade + l (toward the center,!
! A sampling blade 7 is formed with an inclination of , and only the object to be measured that falls onto the sampling blade 7 is guided to the sample collection channel 8 and becomes a sample 9.
回転羽根車４は支持部１４で水モに支持され。The rotary impeller 4 is supported by the water moat at the support part 14.

。It is set so that it can rotate freely with as little resistance as possible, and when the measured object 5 falls onto the axial flow blade 3 as shown in FIG. 3 and flows in the direction of arrow 11 in Fig. 2, the falling energy causes a reaction force on the axial flow blade, and the water component force causes the rotating blade 4 to move in the direction of arrow 12. Rotate. This principle is, so to speak, the same as that of the city and windmills.

となり羽根ＩＦを回転させるに充分な回転力を生じた。In the experimental example, the vertical falling speed of the object to be measured 5 is V = 3 to 5 m.

(2) Sufficient rotational force was generated to rotate the blade IF.
この回転力は（１）式からＩＪＩらかなように被測定物

も変化する。This rotational force is proportional to the amount of missing pieces Q of the object to be measured, as shown by IJI from equation (1), so when the missing pieces change, the rotational speed also changes.

。In addition, for sampling r-, a sample of 176 divisions or 1/8 division is sampled every time the rotary impeller rotates once, but if necessary, samples can be divided into 2/6 division, 2/8 division, I3 division, etc. By changing the divided locations sampled, and by appropriately setting the angle of inclination of the axial flow vane 3, the object to be measured can fall. : The rotational force also changes, and the sampling time interval also changes.
従って、サンプラとしての必要条件である被測定物の通
ｉＭ Ｆａに応じた比例性と縮分操作を一括して行うこ

件ヒの制約も少ない。Therefore, proportionality and reduction operations according to the iM Fa of the object to be measured, which are necessary conditions for a sampler, can be performed at once. Furthermore, since no special drive device is required, there are fewer restrictions on installation conditions.
またこの装置を第４図に示すように何Ｍｌかの組合せで
設置することで更に縮分比をＬげることができる。Moreover, by installing this device in combination with several Ml as shown in FIG. 4, the reduction ratio can be further increased.

れる。In FIG. 4, the sampler la is the largest in size, and as the samplers 1b and 1c increase, the device size gradually decreases to approximately 1/6 to 1/8. When three samplers with 176 divisions are connected in series, the final sampling F
M is about 1/216 of the flow rate of the object to be measured, and with three 1/8-dividing samplers, it is reduced to 11512 and extracted.
次に１本発明のサンプラは駆動装こがなく、被測定物の
落下の慣性で回転する構造であるので。Secondly, the sampler of the present invention does not have a driving mechanism and has a structure in which it rotates by the inertia of the falling object.
特に被測定物が急激に減少時、慣性のため回転体の回転
数の追従が遅れる可能性があるため、必要に応じて第５
図〜第７図に示すような回転数調整装置１４を軸１に付
設する。Particularly when the number of objects to be measured rapidly decreases, there may be a delay in tracking the rotational speed of the rotating body due to inertia.
A rotation speed adjusting device 14 as shown in FIGS. 7 to 7 is attached to the shaft 1.
実施例の装置１４の構造は二重のシリンダ構造で、内筒
のシリンダ１５にはＦ部の円周りに開口１７が設けられ
、内筒１５の外壁及び外１３１６の内壁にはフィン状の
羽根１８が設けられている。The structure of the device 14 of the embodiment is a double cylinder structure, and the inner cylinder 15 is provided with an opening 17 around the circle of the F section, and the outer wall of the inner cylinder 15 and the inner wall of the outer 1316 are provided with fin-shaped blades. 18 are provided.
また外筒１６は円筒１５と縁が切ってあり、フレーム１
９に固定されている。内０１５のフィン状の羽根１８の
取付部より下部にある程度の粘性を持った液体２０（例
えば鍼油など）が充填されており、内筒１５は回転羽根
の回転軸２に連結されている。In addition, the outer cylinder 16 has a cut edge with the cylinder 15, and the frame 1
It is fixed at 9. A liquid 20 having a certain degree of viscosity (for example, acupuncture oil) is filled below the attachment part of the fin-shaped blade 18 in the inner cylinder 15, and the inner cylinder 15 is connected to the rotating shaft 2 of the rotating blade.
連結された回転軸２が静止の状態の時は第５図のように
液体２０のレベルが内、外筒とも同じレベルであるが、
回転軸２が回転し、内筒１５もそれにつれて回転を始め
れば液体２０に遠心力が生じ、第７図に示すように内筒
１５内の液体２０は開［１１７より外筒１６内に溢れ出
て、外筒１６内の液面レベルがＬ昇する。When the connected rotating shaft 2 is in a stationary state, the level of the liquid 20 is the same in both the inner and outer cylinders as shown in FIG.
When the rotating shaft 2 rotates and the inner cylinder 15 also begins to rotate, a centrifugal force is generated in the liquid 20, and as shown in FIG. The liquid level in the outer cylinder 16 rises by L.
外筒内の液面レベルは、内筒の回転がさらに上ると大き

フィン１８の取付位置まで達するため、液体２０を介し
ての内筒の回転力に抵抗を生ずる。フィンの形状は、液
面が上る程、抵抗力が比例して大きくなるように形成さ
れている。As the rotation of the inner cylinder increases, the liquid level inside the outer cylinder further increases due to the large centrifugal force, and finally reaches the mounting position of the fins 18 on the inner and outer cylinders. This creates resistance to the rotational force of the inner cylinder. The shape of the fins is such that as the liquid level rises, the resistance force increases proportionally.
これによって、内筒の回転力は回転数がある程度高い点
では制動トルクが働くので、この回転数調整装置を前述
のサンプラに取付けた場合、被測定物が急激に減少する
と回転羽根車の回転も慣性による持続力が少ないため対
応して減速する。As a result, braking torque acts on the rotational force of the inner cylinder at a point where the rotational speed is high to a certain extent, so when this rotational speed adjustment device is installed on the sampler mentioned above, if the object to be measured suddenly decreases, the rotation of the rotary impeller will also stop. Since the sustaining force due to inertia is small, the speed will be reduced accordingly.
第５図〜第７図の例では液体による回転数調整装置の例
をあげたが、渦電流を利用する電磁装置や、重錘の遠心
力をｆｌｌ用する装置などを用いることももちろん１１
俺である。In the examples shown in Figures 5 to 7, we have given an example of a rotation speed adjustment device using a liquid, but it is also possible to use an electromagnetic device that uses eddy current, a device that uses the centrifugal force of a weight, etc.
It's me.
