本発明は、高圧式空気輸送における塊状体あるいは粉粒
体の輸送系への供給に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the supply of agglomerates or granules to a transport system in high-pressure pneumatic transport.
空気輸送は、１気圧未満の圧力空気を使用する低圧式と
、１気圧以上の圧力空気を用いて輸送する高圧式に大別
される。Pneumatic transport is broadly divided into low-pressure methods that use air under a pressure of less than 1 atm, and high-pressure methods that use air under a pressure of 1 atm or more.
低圧式空気輸送においては塊状体もしくは粉粒体を輸送
系へ供給するのに通常多翼ロータのロータリフィーダが
普遍化されており、輸送系の背圧に抗して被輸送物の落
下供給を定量的に安定させるためロータ翼端とケーシン
グとの隙間を極小とすることによって鎖部のリーク量を
僅少にする工夫がなされており、又安定供給を阻害する
ブリッジ性をもつ粉粒体などに対してはロータリフィー
ダの上方に抽気装置を設けて、背圧によって逆流する空
気を上方のサイロまたはバッグフィルタなどへ抽気する
方法がとられている。しかしこの場合、抽気することに
よってリーク量の絶対量が増加する欠陥が生じる。これ
らロータリフィーダにおいてリーク量を減少させるため
には、ロータと’ｙ−シンク間ならびにロータとヤイド
ゥオー／Ｌ’ノ隙間司法および隙間長さを減少せしめる
必要があるが、１作上、使用上の観点から現在では既に
実用の限界に達していると考えられ、この手法によるこ
れ以上の向上は極めて困難である。In low-pressure pneumatic transportation, rotary feeders with multi-blade rotors are commonly used to feed lumps or powder to the transportation system, and they are used to feed objects falling against the back pressure of the transportation system. In order to achieve quantitative stability, the gap between the rotor blade tip and the casing is minimized to minimize the amount of leakage from the chain. In contrast, a method has been adopted in which an air bleed device is provided above the rotary feeder to bleed the air that flows back due to back pressure to an upper silo, bag filter, or the like. However, in this case, a defect occurs in which the absolute amount of leakage increases due to air bleed. In order to reduce the amount of leakage in these rotary feeders, it is necessary to reduce the clearance between the rotor and the Y-sink, as well as between the rotor and the Y-sink, and the length of the gap between the rotor and the rotary feeder. It is thought that the practical limit has already been reached, and further improvement using this method is extremely difficult.
これらの事から、高圧式空気輸送に上記のロータリフィ
ーダをそのまま採用することは困難である。すなわち、
隙間寸法、隙間長さが同一の精度において、その背圧差
（上下差圧）が例えば５ｋＱ／ｄとすれば低圧式空気輸
送の場合に比ベリーク量は、２．２倍内至８．２倍以上
におよび、更にロータ翼の空間の置換空気量も無視でき
なくなり、圧力空気の損耗もさることながら、輸送系へ
の供給が極めて困難となり少くとも安定した供給は不可
能となるのである。For these reasons, it is difficult to directly employ the rotary feeder described above for high-pressure pneumatic transportation. That is,
If the gap size and gap length are the same and the back pressure difference (vertical pressure difference) is, for example, 5 kQ/d, then in the case of low-pressure pneumatic transportation, the specific vereek amount will be 2.2 times to 8.2 times. In addition to the above, the amount of replacement air in the space of the rotor blades cannot be ignored, and in addition to the loss of pressurized air, it becomes extremely difficult to supply the air to the transportation system, and at least a stable supply becomes impossible.
従って、高圧式空気輸送の場合の供給装置としては圧力
容器内に被輸送物を貯溜し容器内の圧力を輸送系と同等
以上に昇圧させ、その圧力によって貯溜した被輸送物を
輸送系に圧し出すブロータンク方式が主流を占めている
。Therefore, as a supply device for high-pressure pneumatic transportation, the material to be transported is stored in a pressure vessel, the pressure inside the container is increased to a level equal to or higher than that of the transport system, and the pressure is used to pressurize the stored material into the transport system. The blow tank method is the mainstream.
然しなから、この方式も万能ではなく被輸送物の性状に
よ°つて、または使用条件によっては採用困難な場合が
ある。However, this method is not universal and may be difficult to adopt depending on the properties of the object to be transported or depending on the conditions of use.
本発明は、かかる現状にある高圧式空電輸送の供給装置
に定量定常性をもったブロータンク方式に代る適用範囲
の広い供給機を提供するものである。The present invention provides a feeder that has a wide range of applicability in place of the blow tank type, which has quantitative stability and has quantitative stability in the current high-pressure pneumatic transport feeder.
すなわち本発明の供給機は、高圧力排出部と低圧力供給
部の背圧差をロータとケーシング及び上下蓋板の間の連
続した閉鎖端面でシールすることによって、在来のロー
タリーフィーダに比ベシール性を飛躍的に向上させるも
のである。In other words, the feeder of the present invention significantly improves sealing performance compared to conventional rotary feeders by sealing the back pressure difference between the high pressure discharge section and the low pressure supply section with the continuous closed end surface between the rotor, casing, and upper and lower cover plates. It is intended to improve the performance.
本発明の構成を実施例に基すいて図面によって説明する

送物によってマテリアルシールの期待もできる。In this embodiment, the supply lower is connected to a silo or hopper (not shown), and is normally filled with materials to be transported such as lumps and powder. When the shaft 1 is rotated by a prime mover (not shown), the rotor 5 integrated with the shaft rotates, and the pocket 6 approaches the supply lower. At that time, the object to be transported is supplied into the pocket 6, and then when the rotor 5 rotates and the pocket 6 matches the discharge port 8 located 180 degrees opposite to the supply lower, the object to be transported is inside the high-pressure transport system. is discharged to. In this way, the high pressure discharge part and the low pressure supply part are 18
Sealed by the continuous seal end faces of the rotor 5 separated by 0 degrees, leakage is always blocked, and no back pressure is applied above the supply lower, so that the transported objects are always stably supplied. or,
Material sealing can also be expected due to the transported materials filling the supply lower from the silo or hopper.

１０から抽気することができる。However, there is actually a slight leakage of pressurized air from the periphery of the rotor 5, and furthermore, there is a rise of pressurized air that replaces the transported object in the pocket 6 formed in the independent compartment, but these If necessary, air can be extracted from the air extraction port 10 on the upper side of the supply lower.

It is possible to constantly and stably supply the transported material to the transport system in a quantitative manner. This means that the rotary feeder of the present invention is an effective feeding device not only for high-pressure transportation, but also for greatly reducing the amount of leakage when feeding into low-pressure transportation pipes.
