ところが、前述したような磁性異物除去装置は、一般に、図９に示すようなインラインシフタ５０１の混合気排出部５１０などに形成されるものであるが、インラインシフタ５０１では、粉粒体の偏流現象が生じることがある。すなわち、図９に示す通り、粉粒体インレット５０４では、Ａ方向矢印で示す方向から粉粒体が供給室５０３に流入するので、篩い部５０５内の図中点線で示すシーブ５０７において、Ｂ方向矢印で示す点線の通り、７時から９時の範囲の網の領域で、ほとんどの粉粒体が篩われ、他の領域の網ではほとんど篩いが行われず、粉粒体の偏った篩い範囲が形成されることがある。これにより、Ｃ方向矢印で示す通り、ある特定の混合気排出部５１０内壁の特定範囲に偏った状態で粉粒体が流下することがあるといった問題がある。したがって、上記の従来の磁性異物除去装置では、その構造上、偏流しながら流下する粉粒体と棒状磁石の接触率が少ないため、除去しきれずに下流に排出され、除去率が低下するという問題がある。また、粉粒体の目詰まりが生じやすく、圧力損失の低減が困難である。さらに、磁性異物除去装置がシフタの混合気排出部５１０に形成し一体化しているため、混合気排出部５１０への取り付け部の形成など、混合気排出部５１０などシフタ本体などの製造が複雑化する問題がある。   However, the magnetic foreign matter removing apparatus as described above is generally formed in the air-fuel mixture discharge portion 510 of the inline shifter 501 as shown in FIG. May occur. That is, as shown in FIG. 9, in the granular material inlet 504, since the granular material flows into the supply chamber 503 from the direction indicated by the A direction arrow, in the sieve 507 indicated by the dotted line in the figure in the sieve portion 505, the B direction As shown by the dotted line in the arrow, most of the granular material is sieved in the area of the mesh from 7 o'clock to 9 o'clock, and almost no sieving is performed in the other area of the net, and the sieving range in which the granular material is biased is Sometimes formed. Thereby, there exists a problem that a granular material may flow down in the state biased to the specific range of the inner wall of a certain specific air-fuel mixture discharge part 510 as shown by the C direction arrow. Therefore, in the above-described conventional magnetic foreign matter removing device, because of the structure, the contact rate between the granular material that flows down while drifting and the rod-shaped magnet is small, so that the removal rate is lowered without being completely removed. There is. Moreover, clogging of the granular material is likely to occur, and it is difficult to reduce the pressure loss. Furthermore, since the magnetic foreign substance removing device is formed and integrated with the shifter mixture discharge portion 510, the manufacture of the shifter body such as the mixture discharge portion 510 is complicated, such as the formation of the attachment portion to the mixture discharge portion 510. There is a problem to do.

本発明によれば、インラインシフタ、空気輸送装置などで前記した粉粒体の偏流現象など不都合な事態が生じたとしても、アウトレットの流路断面を狭くし、粉粒体を集合させた上で、管内の磁性除去部を回転させることにより、粉粒体との接触率を増大させ、磁性異物を十分に除去した状態で下流に排出することができ、磁性異物の除去率が高くなる効果がある。また、空気輸送ラインに設置した磁性異物除去部が回転することで、粉粒体の目詰まりを防止し、かつ、圧力損失を低減できる上、安定した混合気を供給できる。さらに、磁性異物除去ユニットを混合気排出部の下端に取り付けるだけでよいので、既存のインラインシフタ、空気輸送装置などへの取り付けがきわめて容易である。磁性異物除去ユニットがインラインシフタの混合気排出部内などに存在しないため、混合気排出部に取り付け部を形成する必要がないなど、混合気排出部などシフタ本体、空気輸送装置などの製造がきわめて容易となる効果がある。   According to the present invention, even if an inconvenient situation such as the above-described drift phenomenon of the granular material occurs in an in-line shifter, an air transportation device, etc., the outlet flow passage section is narrowed and the granular material is assembled. By rotating the magnetic removal part in the tube, the contact rate with the powder particles can be increased, and the magnetic foreign matter can be discharged downstream in a sufficiently removed state, which has the effect of increasing the magnetic foreign matter removal rate. is there. In addition, the magnetic foreign matter removing portion installed in the pneumatic transportation line rotates, so that clogging of the granular material can be prevented, pressure loss can be reduced, and a stable air-fuel mixture can be supplied. Furthermore, since it is only necessary to attach the magnetic foreign substance removing unit to the lower end of the air-fuel mixture discharge portion, it is very easy to attach to an existing in-line shifter, pneumatic transport device, or the like. Since there is no magnetic foreign substance removal unit in the mixture discharge part of the inline shifter, it is not necessary to form a mounting part in the mixture discharge part, making it easy to manufacture the shifter body such as the mixture discharge part, pneumatic transport device, etc. There is an effect.

以下、本発明実施形態のインラインシフタ１について、第１図〜第６図を参照して説明する。このインラインシフタ１は、図１、図２、図４、図５に示す、支持脚２ａを有する架台２、空気輸送されてくる粉体と空気の混合気を受け入れる混合気受入部３と、図３及び図５に示す、混合気受入部３と接続され上流のブロア及びロータリーバルブ等（図示略）を経て上流ラインＬ１から供給されてくる混合気を混合気受入部３へ供給する丸形の管である混合気インレット４と、図１〜図５に示す、混合気受入部３が一端部に固定され混合気受入部３と内部が横方向に連通する篩い部５と、図５に示す通り、混合気受入部３及び篩い部５内部に水平方向に配置された回転軸６と、図１〜図５に示す、篩い部５に配置された円筒状のシーブ７と、図５に示す、回転軸６と一体的に形成され、シーブ７内部に拡がり回転可能に配置された風力増幅装置としてのブースター８と、図１〜図３に示す、篩い部５に設けられ、シーブ７を通過できないものを取り出したり内部を点検するための点検扉９と、図１、図４及び図５に示す、篩い部５の下部に設けられ、シーブ７を通過した粉体を下流ラインＬ２に排出するためインラインシフタ１の篩い部５の下部に取り付けられたホッパ形状の混合気排出部１０と、図１及び図３に示す、回転軸６を回転するモータ１１と、図１、図２、図４及び図５に示す、点検扉９に取り付けられ異物を貯留する異物貯留部１２と、図６及び図７に示す、混合気排出部１０の下端に接続されるインライン磁性異物除去装置３１と、を備えたものである。インライン磁性異物除去装置３１を除いた構造の詳細な説明は省略するが、特許第３４９２６７６号等を参照されたい。   Hereinafter, an inline shifter 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 6. The in-line shifter 1 includes a gantry 2 having support legs 2a, an air-fuel mixture receiving portion 3 that receives an air-fuel mixture of powder and air, as shown in FIG. 1, FIG. 2, FIG. 4, and FIG. 3 and FIG. 5, a round shape that is connected to the air-fuel mixture receiving section 3 and supplies the air-fuel mixture supplied from the upstream line L1 to the air-fuel mixture receiving section 3 through an upstream blower, a rotary valve, and the like (not shown). The air-fuel mixture inlet 4 which is a tube, the sieve portion 5 shown in FIGS. 1 to 5, in which the air-fuel mixture receiving portion 3 is fixed to one end and the air-fuel mixture receiving portion 3 communicates with the inside in the lateral direction, and FIG. As shown in FIG. 5, the rotary shaft 6 disposed in the horizontal direction inside the air-fuel mixture receiving part 3 and the sieve part 5, the cylindrical sheave 7 arranged in the sieve part 5 shown in FIGS. The wind power is formed integrally with the rotary shaft 6 and spreads in the sheave 7 so as to be rotatable. A booster 8 as an apparatus, an inspection door 9 provided in the sieving portion 5 shown in FIGS. 1 to 3 for taking out what cannot pass through the sheave 7 and inspecting the inside, and FIGS. 1, 4 and 5 A hopper-shaped air-fuel mixture discharge part 10 attached to the lower part of the sieving part 5 of the in-line shifter 1 for discharging the powder that has passed through the sheave 7 to the downstream line L2, as shown in FIG. 1 and 3, a motor 11 that rotates the rotating shaft 6, a foreign matter storage unit 12 that is attached to the inspection door 9 and stores foreign matter, as shown in FIGS. 1, 2, 4, and 5, and FIG. 6. And an in-line magnetic foreign substance removing device 31 connected to the lower end of the air-fuel mixture discharge section 10 shown in FIG. A detailed description of the structure excluding the inline magnetic foreign matter removing device 31 is omitted, but refer to Japanese Patent No. 3492676.

つぎにインライン磁性異物除去装置３１について図６及び図７を参照して説明する。このインライン磁性異物除去装置３１は、太径部３２、縮径部３３、細径部３４を備え、太径部３２の上部に第１開口部３５、左側面に第２開口部３６、右側面に第３開口部３７を有する管３８を備えている。この管３８の内部において、混合気の流路が上方から横方向に変更されることとなる。太径部３２の内部は磁性除去室３９となっている。第１開口部３５が混合気排出部１０の下端に接続し、これにより篩下の粉粒体を含む混合気を受け入れ、第３開口部３７から空気輸送ラインＬ２に混合気を送出するようになっている。また、インライン磁性異物除去装置３１は、管３８に着脱自在に取り付けられ混合気に混入した磁性異物を除去する磁性異物除去ユニット５０を備えている。管３８と混合気排出部１０は継手で脱着自在に構成されている。たとえば、フェルール４１（図７参照）が、第１開口部３５と混合気排出部１０の下端部の両方に形成されて、フェルール４１が接合可能とされ、図６に示す通り、クランプ４２により、フェルールを緩締することで、インライン磁性異物除去装置３１と混合気排出部１０とが脱着自在な構造となっている。   Next, the inline magnetic foreign matter removing apparatus 31 will be described with reference to FIGS. The in-line magnetic foreign matter removing apparatus 31 includes a large diameter portion 32, a reduced diameter portion 33, and a small diameter portion 34, a first opening 35 on the upper portion of the large diameter portion 32, a second opening 36 on the left side, and a right side. A tube 38 having a third opening 37 is provided. Inside the tube 38, the flow path of the air-fuel mixture is changed from the upper side to the horizontal direction. The inside of the large diameter portion 32 is a magnetic removal chamber 39. The first opening 35 is connected to the lower end of the air-fuel mixture discharge unit 10, thereby receiving the air-fuel mixture containing the powder particles under the sieve and sending the air-fuel mixture from the third opening 37 to the air transport line L 2. It has become. The in-line magnetic foreign matter removing device 31 includes a magnetic foreign matter removing unit 50 that is detachably attached to the tube 38 and removes magnetic foreign matter mixed in the air-fuel mixture. The pipe 38 and the air-fuel mixture discharge part 10 are configured to be detachable by a joint. For example, a ferrule 41 (see FIG. 7) is formed at both the first opening 35 and the lower end portion of the air-fuel mixture discharge unit 10 so that the ferrule 41 can be joined. As shown in FIG. By loosely tightening the ferrule, the in-line magnetic foreign matter removing device 31 and the air-fuel mixture discharging unit 10 are detachable.

この磁性異物除去ユニット５０が、管３８内の磁性除去室３９内に横方向に配置される複数の棒状で水平に配置される磁性異物除去部５１と、磁性異物除去部５０を前面に取り付ける固定板５２と、固定板５２の後面から後方に軸方向（水平方向）に突出する回転軸５３と、図６に示す、回転軸５３を回転させる回転駆動部であるモータ５４と、磁性除去室３９とモータ室（図示略）とを仕切る隔壁５５と、を備えている。管３８とカバー５８は継手で脱着自在に構成されている。例えば、図７に示す通り、フェルール５６，５７がそれぞれ第２開口部３６と、磁性異物除去ユニット５０のカバー５８の右端開口部５９に形成され、クランプ６０により、管３８とカバー５８とが着脱自在に構成してある。磁石の磁力によって非磁性カバーの表面に除去された磁性異物が蓄積されると磁性異物除去効率が落ちるので、表面に蓄積された磁性異物を定期的に除去する必要があり、また、食品、医薬品等の粉体のコンタミネーション（腐敗による汚染等）を解消し衛生確保を一層推進するため、インライン磁性異物除去装置３１の内部の点検、清掃、分解等を可能とする必要があるからである。また、ここではモータ５４は、一例として、直交軸モータが挙げられ、中空回転軸６１（図６参照）に回転軸５３が固定される。隔壁５５の貫通穴と回転軸５３にはシール（図示略）が設けてある。   The magnetic foreign matter removing unit 50 has a plurality of sticks arranged horizontally in the magnetic removal chamber 39 in the tube 38, and a horizontally installed magnetic foreign matter removing portion 51 and a magnetic foreign matter removing portion 50 fixed to the front. A plate 52, a rotary shaft 53 protruding rearward from the rear surface of the fixed plate 52 in the axial direction (horizontal direction), a motor 54 that is a rotary drive unit that rotates the rotary shaft 53 shown in FIG. And a partition wall 55 that partitions the motor chamber (not shown). The tube 38 and the cover 58 are configured to be detachable by a joint. For example, as shown in FIG. 7, ferrules 56 and 57 are respectively formed in the second opening 36 and the right end opening 59 of the cover 58 of the magnetic foreign matter removing unit 50, and the tube 38 and the cover 58 are attached and detached by the clamp 60. It is configured freely. If magnetic foreign matter removed on the surface of the non-magnetic cover accumulates due to the magnetic force of the magnet, the magnetic foreign matter removal efficiency falls, so it is necessary to periodically remove the magnetic foreign matter accumulated on the surface, and food, pharmaceuticals This is because it is necessary to make it possible to inspect, clean, and disassemble the inside of the in-line magnetic foreign matter removing apparatus 31 in order to eliminate contamination (contamination due to corruption, etc.) of the powder and to further promote hygiene. Further, here, as an example of the motor 54, an orthogonal axis motor can be cited, and the rotating shaft 53 is fixed to the hollow rotating shaft 61 (see FIG. 6). A seal (not shown) is provided in the through hole of the partition wall 55 and the rotary shaft 53.

磁性異物除去部５１は、詳細は略すが、非磁性カバー、磁石（永久磁石が好ましい）、及びリングから構成されている。ここでは、非磁性カバーはステンレス、アムミニウム、アルミニウム合金、硬質プラスチック等が挙げられ、磁性のないもの、又は磁性の弱いものが含まれる。磁石は、鉄粉、鉄片等の磁性異物が微小である場合や、弱磁性体からなる場合でも、磁石の磁力によって非磁性カバー表面上に強力に吸着除去させることが可能である。   Although details are omitted, the magnetic foreign matter removing unit 51 includes a nonmagnetic cover, a magnet (preferably a permanent magnet), and a ring. Here, examples of the nonmagnetic cover include stainless steel, aluminium, an aluminum alloy, hard plastic, and the like, and examples include a non-magnetic cover and a weakly magnetic cover. The magnet can be strongly adsorbed and removed on the surface of the nonmagnetic cover by the magnetic force of the magnet even when the magnetic foreign matter such as iron powder or iron piece is very small or made of a weak magnetic material.

以上説明したインラインシフタ１及びインライン磁性異物除去装置３１によれば、先ず、混合気インレット４に上流ラインＬ１を接続し、混合気排出部１０にインライン磁性異物除去装置３１を接続している。その第３開口部３７に下流ラインＬ２を接続し、モータ１１が回転することで回転軸６及びブースター８が一体的に回転し、混合気インレット４から粉体と空気の混合気が接線方向に混合気受入部３の供給室３ａに連続的に供給されると、篩い部５の篩い処理室５ａの内部に強制的に流れ込んでシーブ７の内側領域７ａに達する。シーブ７の内部では、回転軸６の回転によりブースター８が高速で回転しているために、ブースター８の羽根８２及び放射形状体８１が混合気を攪拌する。ブースター８が攪拌を開始すると、羽根８２が行なう混合気の攪拌により粉体のダマ取り、ダマ崩しが行なわれる。シーブ７の網目に張り付いた粉体のダマは羽根８２で払われる。こうしてシーブ７の網目より細かな粉体を含む混合気がシーブ７の外側領域に送り出され、混合気は混合気排出部１０に達し、下方に向かって流れる。そして、下方に行くに従って粉粒体を集合状態とし、インライン磁性異物除去装置３１が磁性異物を除去する。磁性異物が除去された混合気は下流ラインＬ２に排出される。一方、シーブ７の網目より大きな粉体或いは異物はシーブ７の内側領域に残留する。   According to the inline shifter 1 and the inline magnetic foreign matter removing device 31 described above, first, the upstream line L1 is connected to the gas mixture inlet 4, and the inline magnetic foreign matter removing device 31 is connected to the gas mixture discharge portion 10. The downstream line L2 is connected to the third opening 37, and when the motor 11 rotates, the rotating shaft 6 and the booster 8 rotate integrally, and the mixture of powder and air from the mixture inlet 4 in the tangential direction. When continuously supplied to the supply chamber 3 a of the air-fuel mixture receiving unit 3, the air flows into the inside of the sieving processing chamber 5 a of the sieving unit 5 and reaches the inner region 7 a of the sheave 7. Inside the sheave 7, the booster 8 is rotating at a high speed by the rotation of the rotating shaft 6, so the blades 82 and the radial shape body 81 of the booster 8 agitate the air-fuel mixture. When the booster 8 starts stirring, the powder is removed by the stirring of the air-fuel mixture performed by the blades 82, and the damage is destroyed. The powder lumps stuck to the mesh of the sheave 7 are removed by the blades 82. In this way, the air-fuel mixture containing finer powder than the mesh of the sheave 7 is sent out to the outer region of the sheave 7, and the air-fuel mixture reaches the air-fuel mixture discharge section 10 and flows downward. Then, as it goes downward, the powder particles are brought into an aggregated state, and the in-line magnetic foreign matter removing device 31 removes the magnetic foreign matter. The air-fuel mixture from which the magnetic foreign matter has been removed is discharged to the downstream line L2. On the other hand, powder or foreign matter larger than the mesh of the sheave 7 remains in the inner region of the sheave 7.

インライン磁性異物除去装置３１の動作の詳細について説明する。運転時は磁性異物除去部５１が回転し、磁性異物除去部５１から発生する磁界の影響を受けて非磁性カバーの表面上に磁性異物が吸着された状態となる。粉粒体は磁石の影響を受けないので、風力によって非磁性カバーから離脱し、第３開口部３７から排出される。一方、磁性異物は非磁性カバーの表面に付着したまま回転を続ける。   Details of the operation of the inline magnetic foreign matter removing apparatus 31 will be described. During operation, the magnetic foreign matter removing unit 51 rotates, and the magnetic foreign matter is attracted onto the surface of the nonmagnetic cover under the influence of the magnetic field generated from the magnetic foreign matter removing unit 51. Since the granular material is not affected by the magnet, it is detached from the nonmagnetic cover by the wind force and discharged from the third opening 37. On the other hand, the magnetic foreign matter continues to rotate while adhering to the surface of the nonmagnetic cover.

このように、インラインシフタ１の篩い運転を繰り返すと、磁性異物除去部５１に磁性異物が吸着・堆積することになる。磁性異物を除去する必要がある時は、運転を停止し、クランプ６０を緩め、そして、ねじを取り外すことで、非磁性カバーから磁石を外して引き抜き、リング（図示略）を非磁性カバーの外周面に沿って移動させることで、リングが磁性異物を払い落とすので、磁性異物除去部５１から磁性異物を回収できる。また、クランプ４２を外すことができるので、内部点検、清掃等が一層容易となる。一方、点検が終わると、前述と逆の手順で取り付け作業が行われる。   As described above, when the sieving operation of the inline shifter 1 is repeated, the magnetic foreign matter is adsorbed and deposited on the magnetic foreign matter removing unit 51. When it is necessary to remove the magnetic foreign matter, the operation is stopped, the clamp 60 is loosened, and the screw is removed to remove the magnet from the nonmagnetic cover and pull out the ring (not shown). By moving along the surface, the ring removes the magnetic foreign matter, so that the magnetic foreign matter can be collected from the magnetic foreign matter removing unit 51. Moreover, since the clamp 42 can be removed, internal inspection, cleaning, etc. are further facilitated. On the other hand, after the inspection is completed, the installation work is performed in the reverse procedure to that described above.

本実施形態によれば、インラインシフタ１で、前記した粉粒体の偏流現象が生じたとしても、混合気排出部１０の流路断面を狭くし、粉粒体を集合させた上で、管３８内での磁性異物除去部５１の回転によって、粉粒体との接触率（密度及び接触面積）を増大させるので、磁性異物を十分に除去した状態で混合気を下流に排出し、磁性異物の除去率を高くすることができる。また、空気輸送ラインに設置した磁性異物除去部５１が回転することで、粉粒体の目詰まりを防止し、かつ、圧力損失を低減できる。さらに、インライン磁性異物除去装置３１を混合気排出部１０の下端に取り付けるだけでよいので、既存のインラインシフタへの取り付けがきわめて容易である。磁性異物除去ユニット５０を混合気排出部１０に直接取り付ける必要がないため、混合気排出部１０に取り付け部を形成する必要もなく、混合気排出部１０などインラインシフタ１の製造がきわめて容易となる効果がある。   According to the present embodiment, even if the above-described drift phenomenon of the granular material occurs in the inline shifter 1, the flow path cross section of the air-fuel mixture discharge unit 10 is narrowed and the granular material is assembled, 38, the contact rate (density and contact area) with the granular material is increased by rotating the magnetic foreign matter removing unit 51, and thus the air-fuel mixture is discharged downstream with the magnetic foreign matter sufficiently removed. The removal rate can be increased. Moreover, clogging of the granular material can be prevented and pressure loss can be reduced by rotating the magnetic foreign matter removing unit 51 installed in the pneumatic transportation line. Furthermore, since it is only necessary to attach the in-line magnetic foreign substance removing device 31 to the lower end of the air-fuel mixture discharge section 10, it is very easy to attach to an existing in-line shifter. Since it is not necessary to attach the magnetic foreign matter removing unit 50 directly to the mixture discharge unit 10, it is not necessary to form an attachment unit in the mixture discharge unit 10, and the in-line shifter 1 such as the mixture discharge unit 10 can be manufactured very easily. effective.

次に上述の実施形態とは別の実施形態を説明する。この実施形態の空気輸送装置１０１は、図８に示す通り、一次空気と粉粒体との混合物を輸送する第１の管１０２と、二次空気を輸送する第２の管１０３と、２つの管１０２、１０３が合流した第３の管１０４とを備え、下流側にて空気を吸引することで、粉粒体を空気輸送するものであり、また、第３の管１０４の下部に前述したインライン磁性異物除去装置３１が脱着自在に接続されたことを特徴とする。二次空気と粉体とが第３の管１０４内で混合されながら、下方に輸送され、インライン磁性異物除去装置３１で磁性異物が除去され、吸引混合気を排出する。なお、第２の管１０３に空気量調整弁１０５を設け、空気量を調整できるようにしてもよい。またはこれに代えて、ダンパー（図示略）を設け、通路が開閉可能な構造としてもよい。本実施形態によれば、空気輸送装置で、粉粒体の偏流現象が生じたとしても、流路断面を狭くし、粉粒体を集合させた上で、管３８内での磁性異物除去部５１の回転によって、粉粒体との接触率（密度及び接触面積）を増大させるので、磁性異物を十分に除去した状態で吸引された混合気を下流に排出し、磁性異物の除去率を高くすることができる。また、空気輸送ラインに設置した磁性異物除去部５１が回転することで、粉粒体を撹拌し、粉粒体の目詰まりを防止し、かつ、圧力損失を低減できる上、安定した混合気を供給することができる。さらに、第３の管１０４の下端に磁性異物除去装置３１を取り付けるだけでよいので、取り付けがきわめて容易であり、また、空気輸送装置１０１の製造がきわめて容易となる効果がある。   Next, an embodiment different from the above-described embodiment will be described. As shown in FIG. 8, the pneumatic transport device 101 of this embodiment includes a first tube 102 that transports a mixture of primary air and powder, a second tube 103 that transports secondary air, and two And the third pipe 104 joined by the pipes 102 and 103, and air is transported by sucking air downstream, and the lower part of the third pipe 104 is described above. The in-line magnetic foreign matter removing device 31 is detachably connected. The secondary air and the powder are transported downward while being mixed in the third pipe 104, the magnetic foreign matter is removed by the in-line magnetic foreign matter removing device 31, and the suction air-fuel mixture is discharged. Note that an air amount adjusting valve 105 may be provided in the second pipe 103 so that the air amount can be adjusted. Alternatively, a damper (not shown) may be provided so that the passage can be opened and closed. According to the present embodiment, even if a powder particle drift phenomenon occurs in the pneumatic transport device, the flow path is narrowed and the powder particles are gathered, and then the magnetic foreign matter removing unit in the pipe 38 is collected. Since the rotation rate of 51 increases the contact rate (density and contact area) with the granular material, the air-fuel mixture sucked in a state where magnetic foreign matter is sufficiently removed is discharged downstream, and the removal rate of magnetic foreign matter is increased. can do. In addition, the magnetic foreign matter removing unit 51 installed in the pneumatic transportation line rotates to agitate the granular material, prevent clogging of the granular material, reduce pressure loss, and provide a stable air-fuel mixture. Can be supplied. Furthermore, since it is only necessary to attach the magnetic foreign substance removing device 31 to the lower end of the third tube 104, the attachment is very easy, and the pneumatic transport device 101 can be manufactured very easily.
