Description

フィルタ清掃用ノズルシステムFilter cleaning nozzle system
　本発明は、筒状フィルタを清掃するためのフィルタ清掃用ノズルシステムに関するものである。 The present invention relates to a filter cleaning nozzle system for cleaning a cylindrical filter.
　各種集塵装置内部に配設されて空気（排気）中の粉塵（ダスト）等を除去するフィルタとして、円筒状または有底円筒状に形成されたバグフィルタ（筒状フィルタ）が知られている。この種のバグフィルタは、一般的に、通気性を有する織布や不織布、または通気性を有する紙などで形成されており、使用するに従って粉塵等が付着して目詰まりするため、定期的な交換が必要とされる。この場合、省資源および経費削減の観点から、バグフィルタに付着した粉塵等を除去して清浄化し、再利用するのが好ましい。このような、需要に対応可能な装置として、特開２００１－２５９５５７号公報に開示されたバグフィルターの濾布清掃用ノズル装置（以下、単に「ノズル装置」ともいう）が知られている。このノズル装置は、圧縮空気供給用の空気ホースにロータリージョイントを介して回転自在に取り付けられるノズル本体を備えて構成されている。この場合、ノズル本体は、軸心部に設けられてロータリージョイントに接続される空気室と、空気室に一端が連通されて放射方向へ延びる４つの空気流路と、各空気流路に対して水平方向に９０°の角度をなすように連通されてノズル本体の外側面において接線方向に空気吹出口が開口する枝流路とを備えて構成されている。このノズル装置では、空気ホースを介して供給された圧縮空気が、ロータリージョイントを通してノズル本体の空気室に導かれ、各空気流路および枝流路を通して各空気吹出口から接線方向外向きに噴出される。この際に、空気吹出口から接線方向に吹き出される圧縮空気によってノズル本体が自動的に回転させられる。また、噴出された圧縮空気がバグフィルタの濾布の内側面に吹き付けられて、この圧縮空気が濾布の内側から外側に通過することにより、濾布の外側面に付着したダストが吹き飛ばされて除去される結果、その部分の目詰りを解消することが可能となっている。 Bag filters (cylindrical filters) formed in a cylindrical shape or a bottomed cylindrical shape are known as filters that are disposed inside various dust collectors and remove dust (dust) in the air (exhaust). . This type of bag filter is generally formed of a woven or non-woven fabric having air permeability, or paper having air permeability, and is clogged with dust and the like as it is used. An exchange is required. In this case, from the viewpoint of resource saving and cost reduction, it is preferable to remove the dust adhering to the bag filter, clean it, and reuse it. As an apparatus capable of meeting such demands, a bag filter cleaning cloth cleaning nozzle apparatus (hereinafter, also simply referred to as “nozzle apparatus”) disclosed in Japanese Patent Application Laid-Open No. 2001-259557 is known. This nozzle device includes a nozzle body that is rotatably attached to an air hose for supplying compressed air via a rotary joint. In this case, the nozzle body includes an air chamber that is provided at the axial center and connected to the rotary joint, four air flow paths that are connected to the air chamber and extend in the radial direction, and each air flow path. The branch channel is configured to be communicated so as to form an angle of 90 ° in the horizontal direction and open in the tangential direction on the outer surface of the nozzle body. In this nozzle device, compressed air supplied through an air hose is guided to the air chamber of the nozzle body through a rotary joint, and is ejected tangentially outward from each air outlet through each air channel and branch channel. The At this time, the nozzle body is automatically rotated by the compressed air blown tangentially from the air outlet. The jetted compressed air is blown to the inner surface of the filter cloth of the bag filter, and the compressed air passes from the inner side to the outer side of the filter cloth, so that the dust attached to the outer surface of the filter cloth is blown away. As a result of removal, clogging of the portion can be eliminated.

　ところが、上記した従来のノズル装置には、以下の問題点が存在する。すなわち、このノズル装置では、各空気吹出口からの圧縮空気の噴出力によってノズル本体を回転させている。しかしながら、圧縮空気の噴出力によって得られるノズル本体の回転力（回転モーメント）には限界があり、圧縮空気の圧力を上昇させたとしてもノズル本体に対して十分に大きな回転力を与えるのは困難である。一方、排気をバグフィルタの内側から外側に向けて通過させて粉塵を除去するタイプの集塵装置では、バグフィルタの内側に粉塵が付着するため、この種の集塵装置に配設されているバグフィルタを清掃する際には、バグフィルタの内側に付着している粉塵とノズル本体の外周面とが接触することがある。この場合、従来のノズル装置では、上記したように、ノズル本体に対して十分に大きな回転力を与えるのが困難なため、付着している粉塵が高温の環境下で固化して、ノズル本体と固化した粉塵との接触によって大きな摩擦抵抗が生じるときにはノズル本体の回転が困難となって、確実な粉塵の除去が困難となるおそれがあるという問題点が存在する。 However, the conventional nozzle device described above has the following problems. That is, in this nozzle device, the nozzle body is rotated by the jet output of compressed air from each air outlet. However, the rotational force (rotational moment) of the nozzle body obtained by the jet output of compressed air is limited, and it is difficult to give a sufficiently large rotational force to the nozzle body even if the pressure of the compressed air is increased. It is. On the other hand, in the type of dust collector that removes dust by passing the exhaust from the inside to the outside of the bag filter, the dust adheres to the inside of the bag filter, so it is disposed in this type of dust collector. When cleaning the bag filter, dust adhering to the inside of the bag filter may come into contact with the outer peripheral surface of the nozzle body. In this case, in the conventional nozzle device, as described above, since it is difficult to give a sufficiently large rotational force to the nozzle body, the adhering dust solidifies in a high temperature environment, and the nozzle body When a large frictional resistance is generated by contact with the solidified dust, it is difficult to rotate the nozzle body, and there is a problem that reliable dust removal may be difficult.
　本発明は、かかる問題点に鑑みてなされたものであり、筒状フィルタに付着した粉塵を確実に除去し得るフィルタ清掃用ノズルシステムを提供することを主目的とする。 The present invention has been made in view of such problems, and a main object of the present invention is to provide a filter cleaning nozzle system that can reliably remove dust adhering to a cylindrical filter.

A nozzle cleaning system comprising a nozzle main body for ejecting compressed gas toward the peripheral wall of the cylindrical filter, and configured to be able to clean the cylindrical filter, wherein the nozzle main body is driven by a driving force of a motor.

While being rotated by configuration jetting the gas.
　また、本発明に係るフィルタ清掃用ノズルシステムは、上記のフィルタ清掃用ノズルシステムにおいて、前記ノズル本体には、前記筒状フィルタの周壁に接触するブラシが配設されている。 Further, in the filter cleaning nozzle system according to the present invention, in the above-described filter cleaning nozzle system, a brush that contacts the peripheral wall of the cylindrical filter is disposed in the nozzle body.

The nozzle body is configured so that one or both rotation mechanisms arbitrarily selected from the above can be mounted, and the cylindrical filter can be cleaned by jetting gas while rotating the nozzle body by one or both rotation mechanisms By configuring, for example, when the amount of dust or the like adhering to the cylindrical filter is small, the nozzle body is rotated only by the rotational force of the gas ejection type rotating mechanism, and the dust adhering to the cylindrical filter or the like By rotating the nozzle body with the rotational force of the electric rotating mechanism or the rotating force of both rotating mechanisms, The dust adhered to can be removed reliably and efficiently.
　また、本発明に係るフィルタ清掃用ノズルシステムによれば、筒状フィルタの周壁に接触するブラシをノズル本体に配設したことにより、例えば、筒状フィルタの周壁の内周面に粉塵等が固着しているとしても、筒状フィルタの周壁に接触しているブラシがノズル本体の回転に伴って摺動することで、固着している粉塵等を確実に剥離して除去することができる。 Further, according to the filter cleaning nozzle system of the present invention, the brush that contacts the peripheral wall of the cylindrical filter is disposed on the nozzle body, so that, for example, dust or the like adheres to the inner peripheral surface of the peripheral wall of the cylindrical filter. Even if the brush is in contact with the peripheral wall of the tubular filter, the brush slides along with the rotation of the nozzle body, so that the adhered dust and the like can be reliably peeled off and removed.

Therefore, according to the filter cleaning nozzle system, dust or the like adhering to the inner peripheral surface of the tubular filter can be more efficiently separated. Moreover, according to the nozzle system for filter cleaning, since the cover rotates relative to the main pipe, the nozzle body can be stabilized by the gyro effect. Furthermore, according to the filter cleaning nozzle system, since the cover rotates relative to the main pipe, the time for communication between the tip of the ejection pipe and the vent of the cover is limited.

The first weight 13 is formed with a positioning projection 13a that can be fitted into a positioning hole 31c formed in a cover body 31 of the cover 2 described later. In this case, the radius of the first weight 13 is defined to be longer than the distance from the central axis of the main pipe 11 to the tip of the ejection pipe 12. That is, the main body 1 is configured such that the distal end portion of the ejection pipe 12 is positioned inside the outer peripheral edge portion of the first weight 13. As shown in the figure, the second weight 14 is formed in substantially the same shape as the first weight 13 except that the positioning projection 13a is not formed, and the insertion hole 14b formed in the center portion. With the main pipe 11 inserted through (see FIG. 2), it is attached to the bottom 11b side of the main pipe 11 by welding or the like.
　カバー２は、本発明におけるカバーの一例であって、図３に示すように、本体部１に対して着脱可能に構成されて、装着状態において本体部１（各噴出管１２）を覆うことが可能となっている（図１参照）。具体的には、カバー２は、図３に示すように、カバー本体３１および固定部材３２を備えて構成されている。カバー本体３１は、全体として、有底円筒状に構成されている。また、カバー本体３１は、その内径が本体部１の最大径（第１ウェイト１３および第２ウェイト１４の直径）よりもやや大径に規定されて、本体部１を嵌入可能に構成されている。また、カバー本体３１の底部３１ｂ（同図では上側の部位）には、主管１１を挿通させる挿通孔３１ｄが形成されると共に、本体部１の第１ウェイト１３に形成されている突起１３ａを嵌入可能な位置決め孔３１ｃが形成されている。また、カバー本体３１の周壁には、噴出管１２の先端部を臨ませる複数（一例として１２）の通気口３１ｅが形成されている。この場合、通気口３１ｅの形成位置は、本体部１に装着された状態において噴出管１２の先端部が通気口３１ｅの縁部に当接または近接するように規定されている。さらに、カバー本体３１の周壁における開口部３１ａ側の外面には、螺条が形成されている。また、カバー本体３１における底部３１ｂ側の周壁には、清掃時においてバグフィルタ３０１の周壁３０１ｂに接触するブラシ３１ｆが配設されている。 The cover 2 is an example of a cover according to the present invention, and is configured to be detachable from the main body 1 as shown in FIG. 3 so as to cover the main body 1 (each jet pipe 12) in the mounted state. This is possible (see FIG. 1). Specifically, as shown in FIG. 3, the cover 2 includes a cover body 31 and a fixing member 32. The cover body 31 is configured as a bottomed cylinder as a whole. The cover main body 31 has an inner diameter that is defined to be slightly larger than the maximum diameter of the main body 1 (the diameters of the first weight 13 and the second weight 14), and is configured so that the main body 1 can be inserted. . In addition, an insertion hole 31d through which the main pipe 11 is inserted is formed at the bottom 31b (the upper portion in the figure) of the cover body 31, and a projection 13a formed on the first weight 13 of the body 1 is fitted. A possible positioning hole 31c is formed. In addition, a plurality of (for example, 12) vent holes 31e that face the tip of the ejection pipe 12 are formed on the peripheral wall of the cover body 31. In this case, the formation position of the vent 31e is defined so that the tip of the ejection pipe 12 is in contact with or close to the edge of the vent 31e when mounted on the main body 1. Further, a thread is formed on the outer surface of the peripheral wall of the cover body 31 on the opening 31a side. A brush 31f that contacts the peripheral wall 301b of the bag filter 301 at the time of cleaning is disposed on the peripheral wall of the cover body 31 on the bottom 31b side.
　固定部材３２は、図３に示すように、全体として、有底円筒状に構成されている。また、固定部材３２の周壁における開口部３２ａ側の内面には、カバー本体３１の螺条と螺合する螺条が形成されている。また、固定部材３２における底部３２ｂ側の周壁には、清掃時においてバグフィルタ３０１の周壁３０１ｂに接触するブラシ３２ｃが配設されている。この場合、固定部材３２は、本体部１を覆ったカバー本体３１に螺合させてカバー本体３１に嵌着されることによってカバー本体３１（カバー２）を本体部１に固定する。なお、ウェイト１４に位置決め用の突起１３ａを形成すると共に、固定部材３２に位置決め孔３１ｃを形成することにより、カバー本体３１および固定部材３２を図３の状態とは上下逆の状態で本体部１に固定する構成を採用することもできる。 As shown in FIG. 3, the fixing member 32 has a bottomed cylindrical shape as a whole. Further, on the inner surface of the peripheral wall of the fixing member 32 on the opening portion 32a side, a thread that is screwed with the thread of the cover main body 31 is formed. A brush 32c that contacts the peripheral wall 301b of the bag filter 301 during cleaning is disposed on the peripheral wall of the fixing member 32 on the bottom 32b side. In this case, the fixing member 32 is screwed into the cover main body 31 that covers the main body 1 and is fitted to the cover main body 31 to fix the cover main body 31 (cover 2) to the main body 1. In addition, by forming the positioning projection 13a on the weight 14 and forming the positioning hole 31c in the fixing member 32, the main body 1 and the cover main body 31 and the fixing member 32 are turned upside down from the state shown in FIG. It is also possible to adopt a configuration that is fixed to the frame.

The power supply unit 42 is a rechargeable power supply (battery) that supplies electric power for driving the motor 43, and is housed in the housing portion of the case 41.
　モーター４３は、ケース４１の収容部に収容されて、制御部の制御に従い、電源部４２から出力される電力によって駆動する。また、モーター４３の回転軸には、図９に示すように、プーリー４３ａが取り付けられている。この場合、モーター４３は、同図に示すように、プーリー４３ａと主管１１に形成された溝１１ｄとの間に掛け渡されたベルト４３ｂを介して主管１１（つまり、本体部１）を回転させる。ベアリング４４は、ケース４１のハウジング部に保持されており、中心孔に挿通された主管１１をケース４１に対して回転可能に保持する。制御部は、無線操作部から送信される操作信号を受信して、その操作信号に従ってモーター４３に供給する電力（具体的には電流値）を増減させることにより、モーター４３の回転を制御する。 The motor 43 is housed in the housing portion of the case 41 and is driven by the electric power output from the power source unit 42 according to the control of the control unit. A pulley 43a is attached to the rotation shaft of the motor 43 as shown in FIG. In this case, as shown in the figure, the motor 43 rotates the main pipe 11 (that is, the main body 1) via a belt 43b stretched between a pulley 43a and a groove 11d formed in the main pipe 11. . The bearing 44 is held by the housing portion of the case 41, and holds the main pipe 11 inserted through the center hole so as to be rotatable with respect to the case 41. The control unit receives the operation signal transmitted from the wireless operation unit, and controls the rotation of the motor 43 by increasing or decreasing the power (specifically, the current value) supplied to the motor 43 according to the operation signal.
　第２回転機構１０４は、本発明における圧縮空気噴出式の回転機構の一例であって、図５に示すように、本体部５１およびフィン５２を備えて構成されている。本体部５１は、円板状の大径部および小径部で構成されている。また、本体部５１の中央部には、主管１１を挿通可能な挿通孔５１ａが形成されている。また、本体部５１の大径部には、挿通孔５１ａに貫通する通気孔５１ｂが形成されている。この場合、本体部５１は、挿通孔５１ａに主管１１が挿通された状態で、小径部に形成されている螺子孔５１ｃに螺子を螺入することによって主管１１に固定される。フィン５２は、本体部５１の外周面における通気孔５１ｂの形成部位の近傍に基端部が固定されている。この場合、フィン５２は、主管１１の噴出口１１ｃおよび本体部５１の通気孔５１ｂを通って本体部５１の半径方向に噴出される圧縮空気の向きを、半径方向に直交する向き（つまり、本体部５１における外周の接線方向）に変更させる機能を有しており、この向きに変更された圧縮空気の噴出力によって本体部５１（第２回転機構１０４）が固定された主管１１（つまり、本体部１）が回転させられる。 The second rotation mechanism 104 is an example of a compressed air ejection type rotation mechanism in the present invention, and includes a main body 51 and fins 52 as shown in FIG. The main body 51 includes a disk-shaped large diameter portion and a small diameter portion. Further, an insertion hole 51 a through which the main pipe 11 can be inserted is formed at the center of the main body 51. The large-diameter portion of the main body 51 is formed with a vent hole 51b that penetrates the insertion hole 51a. In this case, the main body 51 is fixed to the main pipe 11 by screwing a screw into a screw hole 51c formed in the small diameter part with the main pipe 11 inserted through the insertion hole 51a. The fin 52 has a base end fixed in the vicinity of a portion where the air hole 51 b is formed on the outer peripheral surface of the main body 51. In this case, the fin 52 has a direction perpendicular to the radial direction (that is, the main body 51), and the direction of the compressed air ejected in the radial direction of the main body 51 through the outlet 11c of the main pipe 11 and the vent hole 51b of the main body 51. The main pipe 11 (that is, the main body 11) has a function of changing in the tangential direction of the outer periphery of the part 51, and the main body part 51 (second rotating mechanism 104) is fixed by the jet output of the compressed air changed in this direction. Part 1) is rotated.
　スペーサ１０５は、後述するように第１回転機構１０３のみによって本体部１を回転させる際に、第２回転機構１０４に代えて主管１１に取り付けられるアタッチメントであって、図６に示すように、通気孔５１ｂが形成されていない点を除き、第２回転機構１０４の本体部５１と同じ形状に構成されている。この場合、スペーサ１０５は、中央部に形成されている挿通孔６１ａに主管１１が挿通された状態で、小径部に形成されている螺子孔６１ｃに螺子を螺入することによって主管１１に固定される。 The spacer 105 is an attachment that is attached to the main pipe 11 in place of the second rotation mechanism 104 when the main body 1 is rotated only by the first rotation mechanism 103, as will be described later. As shown in FIG. It is configured in the same shape as the main body 51 of the second rotation mechanism 104 except that the pores 51b are not formed. In this case, the spacer 105 is fixed to the main pipe 11 by screwing a screw into the screw hole 61c formed in the small diameter part in a state where the main pipe 11 is inserted into the insertion hole 61a formed in the center part. The
　ロータリージョイント１０６は、本発明における回転継手の一例であって、図７に示すように、空気供給管１１０の先端部が接続される円筒状の大径部（同図における上部）と、本体部１における主管１１の開口部１１ａ側が接続される小径部（同図における下部）とで構成されている。この場合、ロータリージョイント１０６は、空気供給管１１０によって供給される圧縮空気を主管１１に送り込みつつ、空気供給管１１０に対する主管１１の回転が可能な状態で両者を連結する機能を有している。 The rotary joint 106 is an example of a rotary joint in the present invention, and as shown in FIG. 7, a cylindrical large-diameter portion (upper portion in the drawing) to which the tip of the air supply pipe 110 is connected, and a main body portion 1 is formed of a small diameter portion (lower portion in the figure) to which the opening 11a side of the main pipe 11 is connected. In this case, the rotary joint 106 has a function of connecting the compressed air supplied from the air supply pipe 110 to the main pipe 11 while connecting the two in a state where the main pipe 11 can rotate with respect to the air supply pipe 110.
　昇降装置１０７は、図８に示すように、ケース７１、モーター７２、一対のローラー７３ａ，７３ｂおよび図外の操作部を備えて構成されて、図１に示すように、キャップ１０８の上部に取り付けられている。モーター７２は、ケース７１に収容されて、操作部の制御に従い、図外の電源（商用電源）からの電力供給によって駆動する。ローラー７３ａ，７３ｂは、空気供給管１１０を挟み込んだ状態で、ローラー７３ａがモーター７２によって回転させられることにより、空気供給管１１０の送り出し、および引き上げを行う。 As shown in FIG. 8, the lifting device 107 includes a case 71, a motor 72, a pair of rollers 73 a and 73 b, and an operation unit that is not shown, and is attached to the upper portion of the cap 108 as shown in FIG. 1. It has been. The motor 72 is housed in the case 71 and driven by power supply from a power source (commercial power source) (not shown) according to the control of the operation unit. The rollers 73a and 73b feed and raise the air supply pipe 110 when the roller 73a is rotated by the motor 72 in a state where the air supply pipe 110 is sandwiched.
　キャップ１０８は、ノズル本体１０２を用いてバグフィルタ３０１を清掃する際に、バグフィルタ３０１から除去された粉塵の周囲への飛散を防止するための部材であって、図１に示すように有底円筒状の本体部８１と、本体部８１の開口部側（同図における下側）に形成された鍔部８２と、本体部８１における鍔部８２の形成位置よりも底部側（同図における上側）に形成されたダクト取付部８３と、本体部８１の開口部（鍔部８２の下側）に形成された複数の嵌合片８６とを備えて構成されている。また、本体部８１の底面（同図における上面）には、空気供給管１１０を挿通可能な挿通孔８４が形成されている。この場合、キャップ１０８は、嵌合片８６をバグフィルタ３０１の開口部３０１ａ側に嵌め込むことによってバグフィルタ３０１に装着可能に構成されている。なお、同図に示すように、ダクト取付部８３の内側に、触媒の働きをする有害物質除去用のフィルタ８３ａを組み込んだ構成を採用することもでき、このように構成することで、バグフィルタ３０１からの粉塵を有害物質を除去した状態で外部に排出することができる。また、キャップ１０８に照明用のライト（図示せず）を装着する構成を採用することもでき、このように構成することで、夜間における作業効率を向上させることができる。 The cap 108 is a member for preventing scattering of dust removed from the bag filter 301 when the bag filter 301 is cleaned using the nozzle body 102, and has a bottomed surface as shown in FIG.

An insertion hole 84 through which the air supply pipe 110 can be inserted is formed on the bottom surface (upper surface in the figure) of the main body 81. In this case, the cap 108 is configured to be attachable to the bag filter 301 by fitting the fitting piece 86 into the opening 301 a side of the bag filter 301. As shown in the figure, it is possible to adopt a configuration in which a filter 83a for removing harmful substances acting as a catalyst is incorporated inside the duct mounting portion 83. By configuring in this way, the bag filter The dust from 301 can be discharged to the outside with the harmful substances removed. Moreover, the structure which mounts | wears with the light for illumination (not shown) to the cap 108 can also be employ | adopted, and the working efficiency at night can be improved by comprising in this way.
　次に、ノズルシステム１０１を用いて、集塵装置のバグフィルタ格納室に配設されているバグフィルタ３０１を清掃する方法の一例について、図面を参照して説明する。 Next, an example of a method for cleaning the bag filter 301 disposed in the bag filter storage chamber of the dust collector using the nozzle system 101 will be described with reference to the drawings.
　まず、清掃に先立ち、本体部１にカバー２を取り付けてノズル本体１０２を組み立てる。具体的には、図３に示すように、カバー２のカバー本体３１を、第１ウェイト１３側から本体部１に覆い被せ、本体部１における主管１１をカバー本体３１の挿通孔３１ｄに挿通させると共に、第１ウェイト１３の突起１３ａをカバー本体３１の位置決め孔３１ｃに嵌合させる。次いで、固定部材３２における周壁の内面に形成されている螺条をカバー本体３１における周壁の外面に形成されている螺条に螺合させることにより、カバー本体３１を本体部１に固定する。以上により、ノズル本体１０２の組立て（本体部１へのカバー２の取り付け）が完了する。 First, prior to cleaning, the cover 2 is attached to the main body 1 and the nozzle main body 102 is assembled. Specifically, as shown in FIG. 3, the cover main body 31 of the cover 2 is covered with the main body 1 from the first weight 13 side, and the main pipe 11 in the main body 1 is inserted into the insertion hole 31 d of the cover main body 31. At the same time, the protrusion 13 a of the first weight 13 is fitted into the positioning hole 31 c of the cover body 31. Next, the cover main body 31 is fixed to the main body portion 1 by screwing the screw formed on the inner surface of the peripheral wall of the fixing member 32 with the screw formed on the outer surface of the peripheral wall of the cover main body 31. Thus, the assembly of the nozzle main body 102 (attachment of the cover 2 to the main body 1) is completed.
　続いて、ノズル本体１０２に第２回転機構１０４を取り付ける。具体的には、図９に示すように、ノズル本体１０２における本体部１の主管１１を第２回転機構１０４における本体部５１の挿通孔５１ａに挿通させる。次いで、本体部５１の小径部に形成されている螺子孔５１ｃに螺子を螺入させることにより、第２回転機構１０４を主管１１に固定する。これにより、第２回転機構１０４の取り付けが完了する。続いて、第２回転機構１０４の上に第１回転機構１０３を配置する。具体的には、ケース４１の第２ケース４１ｂを取り外した状態で、ベアリング４４の中心孔に主管１１を挿通させる。次いで、同図に示すように、主管１１に形成されている溝１１ｄとモーター４３に取り付けられているプーリー４３ａとの間にベルト４３ｂに架け渡す。続いて、ケース４１の第１ケース４１ａに第２ケース４１ｂを嵌合させて螺子止めする。これにより、第１回転機構１０３の配置が完了する。 Subsequently, the second rotating mechanism 104 is attached to the nozzle body 102. Specifically, as shown in FIG. 9, the main pipe 11 of the main body 1 in the nozzle main body 102 is inserted through the insertion hole 51 a of the main body 51 in the second rotation mechanism 104. Next, the second rotation mechanism 104 is fixed to the main pipe 11 by screwing a screw into a screw hole 51 c formed in the small diameter portion of the main body 51. Thereby, the attachment of the second rotation mechanism 104 is completed. Subsequently, the first rotation mechanism 103 is disposed on the second rotation mechanism 104. Specifically, the main pipe 11 is inserted through the center hole of the bearing 44 with the second case 41 b of the case 41 removed. Next, as shown in the figure, the belt 43 b is bridged between a groove 11 d formed in the main pipe 11 and a pulley 43 a attached to the motor 43. Subsequently, the second case 41b is fitted into the first case 41a of the case 41 and screwed. Thereby, arrangement | positioning of the 1st rotation mechanism 103 is completed.
　次いで、空気供給管１１０の先端部を、昇降装置１０７におけるローラー７３ａ，７３ｂの間およびキャップ１０８の挿通孔８４に挿通させる。続いて、空気供給管１１０の先端部をロータリージョイント１０６の大径部に接続する。次いで、第２回転機構１０４の取り付けおよび第１回転機構１０３の配置が完了したノズル本体１０２における主管１１の開口部１１ａ側をロータリージョイント１０６の小径部に接続する。この際に、第１回転機構１０３におけるケース４１の接合部がロータリージョイント１０６における大径部に嵌合する。続いて、ケース４１の接合部に形成されている螺子孔４１ｃに螺子を螺入させることにより、ケース４１（つまり第１回転機構１０３）をロータリージョイント１０６に固定する。次いで、図１０に示すように、バグフィルタ３０１の開口部３０１ａ側にキャップ１０８の嵌合片８６を嵌め込んで装着すると共に、キャップ１０８のダクト取付部８３に集塵用のダクト８５を連結し、さらに、ダクト８５の先端部に図外の集塵袋を取り付ける。 Next, the tip of the air supply pipe 110 is inserted between the rollers 73 a and 73 b in the lifting device 107 and the insertion hole 84 of the cap 108. Subsequently, the distal end portion of the air supply pipe 110 is connected to the large diameter portion of the rotary joint 106. Next, the opening 11 a side of the main pipe 11 in the nozzle body 102 in which the attachment of the second rotation mechanism 104 and the arrangement of the first rotation mechanism 103 has been completed is connected to the small diameter portion of the rotary joint 106. At this time, the joint portion of the case 41 in the first rotation mechanism 103 is fitted to the large diameter portion in the rotary joint 106. Subsequently, the case 41 (that is, the first rotation mechanism 103) is fixed to the rotary joint 106 by screwing a screw into a screw hole 41 c formed in the joint portion of the case 41. Next, as shown in FIG. 10, the fitting piece 86 of the cap 108 is fitted and attached to the opening 301 a side of the bag filter 301, and a dust collecting duct 85 is connected to the duct mounting portion 83 of the cap 108. Further, a dust collection bag (not shown) is attached to the tip of the duct 85.
　続いて、空気供給管１１０を図外のエアコンプレッサに接続し、次いで、エアコンプレッサからの圧縮空気の供給を開始する。この際に、エアコンプレッサから供給される圧縮空気が空気供給管１１０を介して開口部１１ａ側から主管１１内部に送り込まれる。続いて、主管１１内に送り込まれた圧縮空気は、主管１１の周壁に取り付けられている噴出管１２に送り込まれて、噴出管１２の先端部からカバー２の通気口３１ｅを通ってバグフィルタ３０１の周壁３０１ｂに向けて噴出される。 Subsequently, the air supply pipe 110 is connected to an air compressor (not shown), and then supply of compressed air from the air compressor is started. At this time, the compressed air supplied from the air compressor is sent into the main pipe 11 from the opening 11 a side through the air supply pipe 110. Subsequently, the compressed air sent into the main pipe 11 is sent to the jet pipe 12 attached to the peripheral wall of the main pipe 11, and the bag filter 301 passes from the tip of the jet pipe 12 through the vent 31 e of the cover 2. Is ejected toward the peripheral wall 301b.
　また、主管１１内部に送り込まれた圧縮空気の一部は、主管１１の噴出口１１ｃおよび第２回転機構１０４における本体部５１の通気孔５１ｂを通って本体部５１の半径方向に噴出され、フィン５２によってその向きが本体部５１における外周の接線方向に変更させられる。このため、この圧縮空気の噴出力によってノズル本体１０２が図１０の矢印Ａの向きに回転する。次いで、昇降装置１０７の操作部を操作して空気供給管１１０を送り出すことにより、ノズル本体１０２をバグフィルタ３０１の長さ方向に沿って開口部３０１ａ側から底部３０１ｃ側に向けて移動させる。 A part of the compressed air sent into the main pipe 11 is jetted in the radial direction of the main body 51 through the outlet 11c of the main pipe 11 and the vent hole 51b of the main body 51 in the second rotating mechanism 104, and the fin The orientation of the main body 51 is changed to the tangential direction of the outer periphery by the main body 51. For this reason, the nozzle body 102 rotates in the direction of arrow A in FIG. Next, the nozzle body 102 is moved from the opening 301 a side to the bottom 301 c side along the length direction of the bag filter 301 by operating the operation unit of the lifting device 107 to send out the air supply pipe 110.
　一方、カバー２に配設されているブラシ３１ｆ，３２ｃがノズル本体１０２の回転に伴ってバグフィルタ３０１における周壁３０１ｂの内面上を摺動する。また、ノズル本体１０２（噴出管１２）から噴出した圧縮空気は、バグフィルタ３０１の周壁３０１ｂに吹き当てられる。これにより、周壁３０１ｂの内面側に付着している粉塵等が、ブラシ３１ｆ，３２ｃの摺動および吹き当てられた圧縮空気の圧力によって周壁３０１ｂから剥離してバグフィルタ３０１内に放散する。この場合、ノズル本体１０２から噴出された圧縮空気によってバグフィルタ３０１内の圧力が上昇しているため、バグフィルタ３０１内に放散した粉塵等は、バグフィルタ３０１内の空気（圧縮空気）と共に、キャップ１０８のダクト取付部８３からダクト８５を通ってバグフィルタ３０１外部に排出され、ダクト８５に取り付けられている図外の集塵袋によって集塵される。また、ノズル本体１０２から噴出した圧縮空気の一部は、バグフィルタ３０１の周壁３０１ｂを通り抜け、これによって周壁３０１ｂの外面側に付着している粉塵等が、周壁３０１ｂから剥離してバグフィルタ３０１とバグフィルタ格納室との間の隙間に放散する。この場合、バグフィルタ３０１と収容容器との間の隙間は外部に対して密閉されているため、この隙間に放散した粉塵等は、周囲に飛散することなくバグフィルタ格納室の底部に落下する。 Meanwhile, the brushes 31f and 32c disposed on the cover 2 slide on the inner surface of the peripheral wall 301b of the bag filter 301 as the nozzle body 102 rotates. The compressed air ejected from the nozzle body 102 (ejection pipe 12) is blown against the peripheral wall 301b of the bag filter 301. As a result, dust or the like adhering to the inner surface side of the peripheral wall 301b is peeled off from the peripheral wall 301b by the sliding of the brushes 31f and 32c and the pressure of the blown compressed air, and diffused into the bag filter 301. In this case, since the pressure in the bag filter 301 is increased by the compressed air ejected from the nozzle body 102, dust or the like diffused in the bag filter 301 is not only a cap but also air (compressed air) in the bag filter 301. The dust is discharged from the duct attaching portion 83 of 108 through the duct 85 to the outside of the bag filter 301 and collected by a dust collecting bag (not shown) attached to the duct 85. Further, a part of the compressed air ejected from the nozzle body 102 passes through the peripheral wall 301b of the bag filter 301, whereby dust or the like adhering to the outer surface side of the peripheral wall 301b is peeled off from the peripheral wall 301b. Dissipates into the gap between the bag filter storage room. In this case, since the gap between the bag filter 301 and the storage container is sealed with respect to the outside, the dust and the like diffused in the gap fall to the bottom of the bag filter storage chamber without being scattered around.
　ここで、例えば、バグフィルタ３０１における周壁３０１ｂの内面側に大量の粉塵等が付着していて、圧縮空気の噴出力（第２回転機構１０４による回転力）だけでは、ノズル本体１０２に対する十分な回転力を得ることができないときには、第１回転機構１０３を用いてノズル本体１０２を回転させる。具体的には、第１回転機構１０３の無線操作部を操作して、モーター４３を駆動（回転）させる。この際に、モーター４３における回転軸の回転力が、プーリー４３ａと主管１１の溝１１ｄとの間に掛け渡されたベルト４３ｂを介して主管１１に伝達される。これにより、第２回転機構１０４による回転力に、第１回転機構１０３におけるモーター４３の回転力が加わり、ノズル本体１０２が十分な回転力で回転する。このため、周壁３０１ｂの内面側に大量の粉塵等が付着してる場合においても、その粉塵等が周壁３０１ｂから剥離して除去される。 Here, for example, a large amount of dust or the like is attached to the inner surface side of the peripheral wall 301b of the bag filter 301, and sufficient rotation with respect to the nozzle body 102 is performed only by the jet output of the compressed air (rotational force by the second rotation mechanism 104). When the force cannot be obtained, the nozzle body 102 is rotated using the first rotation mechanism 103. Specifically, the wireless operation unit of the first rotation mechanism 103 is operated to drive (rotate) the motor 43. At this time, the rotational force of the rotation shaft of the motor 43 is transmitted to the main pipe 11 via the belt 43b that is stretched between the pulley 43a and the groove 11d of the main pipe 11. Thereby, the rotational force of the motor 43 in the first rotational mechanism 103 is added to the rotational force of the second rotational mechanism 104, and the nozzle body 102 rotates with sufficient rotational force. For this reason, even when a large amount of dust or the like adheres to the inner surface side of the peripheral wall 301b, the dust or the like is peeled off from the peripheral wall 301b and removed.
　続いて、清掃を終了する際には、コンプレッサを停止させて圧縮空気の供給を停止させると共に、第１回転機構１０３の無線操作部を操作して、モーター４３を停止させる。次いで、昇降装置１０７の操作部を操作して空気供給管１１０を引き上げることにより、バグフィルタ３０１の開口部３０１ａ側（つまりキャップ１０８側）にノズル本体１０２、第１回転機構１０３および第２回転機構１０４を移動させる。続いて、キャップ１０８を昇降装置１０７と共にバグフィルタ３０１から取り外し、次いで、第１回転機構１０３および第２回転機構１０４と共にノズル本体１０２をバグフィルタ３０１から引き抜く。以上により、１つのバグフィルタ３０１の清掃が終了する。以下、他のバグフィルタ３０１の清掃を行う際には、上記した作業を繰り返して実行する。この場合、このノズルシステム１０１では昇降装置１０７を用いて空気供給管１１０の送り出しおよび引き上げを行っている。このため、手作業でこれらの動作を行う構成と比較して、数多くのバグフィルタ３０１の清掃を連続して行う際においても、作業者に対する負担を軽減することが可能となっている。 Subsequently, when the cleaning is finished, the compressor is stopped to stop the supply of compressed air, and the wireless operation unit of the first rotating mechanism 103 is operated to stop the motor 43. Next, the nozzle body 102, the first rotation mechanism 103, and the second rotation mechanism are disposed on the opening 301 a side (that is, the cap 108 side) of the bag filter 301 by operating the operation unit of the lifting device 107 to pull up the air supply pipe 110. 104 is moved. Subsequently, the cap 108 is removed from the bag filter 301 together with the lifting device 107, and then the nozzle body 102 is pulled out of the bag filter 301 together with the first rotating mechanism 103 and the second rotating mechanism 104. Thus, the cleaning of one bag filter 301 is completed. Hereinafter, when the other bag filter 301 is cleaned, the above-described operation is repeated. In this case, in the nozzle system 101, the air supply pipe 110 is sent out and pulled up using the lifting device 107. For this reason, it is possible to reduce the burden on the operator even when a large number of bag filters 301 are continuously cleaned as compared with a configuration in which these operations are performed manually.
　一方、このノズルシステム１０１では、ノズル本体１０２に第１回転機構１０３および第２回転機構１０４のいずれか一方のみを取り付けてその一方の回転機構のみによってノズル本体１０２を回転させつつ清掃を行うことが可能となっている。例えば、第１回転機構１０３のみをノズル本体１０２に取り付けてノズル本体１０２を回転させる際には、第２回転機構１０４に代えて、スペーサ１０５を第１回転機構１０３の下側に取り付ける。この場合、第１回転機構１０３のみを用いる（つまり第２回転機構１０４を用いない）ときには、第２回転機構１０４によって圧縮空気が使用されない分、ノズル本体１０２（噴出管１２）から噴出させる圧縮空気の圧力および量を増加させることができる。 On the other hand, in the nozzle system 101, only one of the first rotation mechanism 103 and the second rotation mechanism 104 is attached to the nozzle body 102, and cleaning is performed while rotating the nozzle body 102 only by the one rotation mechanism. It is possible. For example, when only the first rotation mechanism 103 is attached to the nozzle body 102 and the nozzle body 102 is rotated, the spacer 105 is attached to the lower side of the first rotation mechanism 103 instead of the second rotation mechanism 104. In this case, when only the first rotation mechanism 103 is used (that is, the second rotation mechanism 104 is not used), the compressed air that is ejected from the nozzle body 102 (the ejection pipe 12) is equivalent to the amount of compressed air that is not used by the second rotation mechanism 104. The pressure and amount of can be increased.
　このように、このノズルシステム１０１によれば、モーター４３の駆動力によってノズル本体１０２を回転させる電動式の第１回転機構１０３、および圧縮空気の噴出力によってノズル本体１０２を回転させる圧縮空気噴出式の第２回転機構１０４を装着可能に本体部１を構成し、いずれか一方または双方の回転機構１０３，１０４によってノズル本体１０２を回転させつつ圧縮空気を噴出させてバグフィルタ３０１を清掃可能に構成したことにより、例えば、バグフィルタ３０１に付着している粉塵等の量が少ないときには、第２回転機構１０４の回転力のみによってノズル本体１０２を回転させ、バグフィルタ３０１に付着している粉塵等の量が多いときには第１回転機構１０３の回転力、または両回転機構１０３，１０４の回転力によってノズル本体１０２を回転させることで、効率的に清掃を行うことができる。 As described above, according to the nozzle system 101, the electric first rotation mechanism 103 that rotates the nozzle body 102 by the driving force of the motor 43, and the compressed air ejection type that rotates the nozzle body 102 by the jet output of the compressed air. The main body 1 is configured so that the second rotation mechanism 104 can be mounted, and the bag filter 301 can be cleaned by jetting compressed air while rotating the nozzle body 102 by one or both of the rotation mechanisms 103 and 104. As a result, for example, when the amount of dust or the like adhering to the bag filter 301 is small, the nozzle body 102 is rotated only by the rotational force of the second rotation mechanism 104, and dust or the like adhering to the bag filter 301 is detected. When the amount is large, the rotational force of the first rotational mechanism 103 or the rotational force of both rotational mechanisms 103 and 104 It By rotating the nozzle body 102, can be performed efficiently cleaned.
　また、このノズルシステム１０１によれば、主管１１に取り付けられて圧縮空気を先端部から噴出させる複数の噴出管１２と、各噴出管１２を覆うカバー２とを備えてノズル本体１０２を構成したことにより、バグフィルタ３０１の周壁３０１ｂから剥離した粉塵等が噴出管１２に付着する事態を確実に防止することができる。 Further, according to the nozzle system 101, the nozzle body 102 is configured by including the plurality of ejection pipes 12 attached to the main pipe 11 and ejecting compressed air from the tip end portion, and the cover 2 covering each ejection pipe 12. Thus, it is possible to reliably prevent the dust or the like peeled off from the peripheral wall 301b of the bag filter 301 from adhering to the ejection pipe 12.
　また、このノズルシステム１０１によれば、カバー２の周壁に、ブラシ３１ｆ，３２ｃを配設したことにより、例えば、バグフィルタ３０１の周壁３０１ｂの内周面に粉塵等が固着しているとしても、ブラシ３１ｆ，３２ｃによって固着している粉塵等を確実に剥離することができる。 Moreover, according to this nozzle system 101, even if dust etc. adhere to the inner peripheral surface of the peripheral wall 301b of the bag filter 301 by arranging the brushes 31f and 32c on the peripheral wall of the cover 2, for example, The dust adhered by the brushes 31f and 32c can be reliably peeled off.
　さらに、このノズルシステム１０１によれば、ノズル本体１０２に連結された空気供給管１１０の送り出しおよび引き上げを行うことによって筒状フィルタの内部に挿入されたノズル本体を上下に移動させる昇降装置１０７を備えたことにより、昇降装置１０７を備えていない構成、つまり手作業でノズル本体１０２の上下の移動を行う構成と比較して、数多くのバグフィルタ３０１の清掃を連続して行う際においても、作業者に対する負担を十分に軽減することができる。 Furthermore, according to this nozzle system 101, the lifting / lowering device 107 that moves the nozzle body inserted into the cylindrical filter up and down by feeding and lifting the air supply pipe 110 connected to the nozzle body 102 is provided. As a result, compared with a configuration in which the lifting / lowering device 107 is not provided, that is, a configuration in which the nozzle main body 102 is moved up and down manually, the operator can also perform many cleanings of the bag filter 301 continuously. Can be sufficiently reduced.
　なお、本発明は上記の構成に限定されない。例えば、上記した本体部１およびカバー２に代えて、図１１に示す本体部２０１および図１２に示すカバー２０２を採用することもできる。この場合、本体部２０１は、図１１に示すように、第１ウェイト１３および第２ウェイト１４がベアリング２１１を介して主管１１に回転可能にそれぞれ取り付けられると共に、主管１１に上記した噴出口１１ｃとは異なる噴出口１１ｅが形成されている点で、上記した本体部１と異なっている。また、カバー２０２は、図１２に示すように、カバー本体２３１および固定部材２３２を備えて構成されている。この場合、カバー本体２３１は、主管１１に形成された噴出口１１ｅから噴出される圧縮空気を受けてカバー２０２を主管１１（本体部２０１）に対して相対的に回転させる回転用フィン２３１ｇが底部２３１ｂに形成されている点で、上記したカバー２のカバー本体３１と異なっている。この本体部２０１およびカバー２０２を備えた構成では、主管１１に送り込まれた圧縮空気の一部が、主管１１の噴出口１１ｅから噴出され、この圧縮空気をカバー２０２の回転用フィン２３１ｇが受けることにより、カバー２０２および本体部２０１の第１ウェイト１３および第２ウェイト１４が主管１１および噴出管１２（本体部２０１）に対して相対的に回転する。このため、この構成では、本体部２０１の回転速度にカバー２０２自体の回転速度が加わる結果、カバー２０２を高速回転させることができる。したがって、この構成では、バグフィルタ３０１の内周面に固着している粉塵等をより効率的に剥離することができる。また、この構成では、カバー２０２および両ウェイト１３，１４が主管１１および噴出管１２に対して相対的に回転するため、ジャイロ効果によってノズル本体１０２を安定化させることができる。さらに、この構成では、カバー２０２が主管１１および噴出管１２に対して相対的に回転するため、噴出管１２の先端部とカバー２０２の通気口３１ｅとが連通する時間が制限される。このため、例えば、エアコンプレッサからの圧縮空気の圧力が高すぎるときに、先端部から噴出させる圧縮空気の圧力や吐出量をカバー２０２の回転によって制限することができる。 In addition, this invention is not limited to said structure. For example, instead of the main body 1 and the cover 2 described above, a main body 201 shown in FIG. 11 and a cover 202 shown in FIG. 12 may be employed. In this case, as shown in FIG. 11, the main body portion 201 includes a first weight 13 and a second weight 14 that are rotatably attached to the main pipe 11 via bearings 211, and the jet outlet 11 c described above in the main pipe 11. Differs from the main body 1 described above in that a different spout 11e is formed. The cover 202 includes a cover main body 231 and a fixing member 232 as shown in FIG. In this case, the cover main body 231 is provided with a rotating fin 231g that receives compressed air ejected from an ejection port 11e formed in the main pipe 11 and rotates the cover 202 relative to the main pipe 11 (main body 201). It is different from the cover main body 31 of the cover 2 described above in that it is formed at 231b. In the configuration provided with the main body 201 and the cover 202, a part of the compressed air sent into the main pipe 11 is ejected from the ejection port 11e of the main pipe 11, and the compressed air is received by the rotation fins 231g of the cover 202. As a result, the first weight 13 and the second weight 14 of the cover 202 and the main body 201 rotate relative to the main pipe 11 and the ejection pipe 12 (main body 201). For this reason, in this configuration, as a result of the rotation speed of the cover 202 itself being added to the rotation speed of the main body 201, the cover 202 can be rotated at a high speed. Therefore, in this configuration, dust or the like adhering to the inner peripheral surface of the bag filter 301 can be more efficiently separated. Further, in this configuration, since the cover 202 and the weights 13 and 14 rotate relative to the main pipe 11 and the ejection pipe 12, the nozzle body 102 can be stabilized by the gyro effect. Furthermore, in this configuration, since the cover 202 rotates relative to the main pipe 11 and the ejection pipe 12, the time during which the tip of the ejection pipe 12 communicates with the vent 31e of the cover 202 is limited. For this reason, for example, when the pressure of the compressed air from the air compressor is too high, the pressure and the discharge amount of the compressed air ejected from the tip can be limited by the rotation of the cover 202.
　また、図１３に示すカバー６０３を採用することもできる。このカバー６０３は、上記したバグフィルタ３０１よりも大径のバグフィルタを清掃する際に用いるカバーであって、カバー本体６４１および固定部材６４２を備えて構成されている。この場合、カバー本体６４１および固定部材６４２の周壁の直径（外径および内径）は、清掃対象のバグフィルタの内径に合わせて、上記したカバー２におけるカバー本体３１および固定部材３２の直径よりもそれぞれ大径に規定されている。また、カバー本体６４１における周壁には、上記した通気口３１ｅと同様の複数（この例では１２）の通気口６４１ｅが形成されている。また、同図に示すように、カバー本体６４１における周壁の内面には、本体部１に装着された状態において噴出管１２の先端部と通気口６４１ｅとを連結するための連結管６５１が各通気口６４１ｅの形成部位に取り付けられている。さらに、各連結管６５１には、噴出管１２の先端部と連結管６５１の先端部とを位置合わせするための樋状の位置合わせ部材６５２が取り付けられている。この場合、直径の異なる複数種類のカバー６０３を用意しておくことで、１つの本体部１を用いて（つまり、噴出管１２の長さが異なる複数種類の本体部１を製作することなく）、内径の異なる複数種類のバグフィルタを効率的に清掃することができる。 Also, the cover 603 shown in FIG. 13 can be adopted. The cover 603 is a cover used when cleaning a bag filter having a diameter larger than that of the bag filter 301 described above, and includes a cover body 641 and a fixing member 642. In this case, the diameters (outer diameter and inner diameter) of the peripheral walls of the cover main body 641 and the fixing member 642 are respectively larger than the diameters of the cover main body 31 and the fixing member 32 in the cover 2 according to the inner diameter of the bag filter to be cleaned. It is specified for large diameter. In addition, a plurality of (12 in this example) vent holes 641e similar to the vent hole 31e described above are formed on the peripheral wall of the cover main body 641. Further, as shown in the figure, on the inner surface of the peripheral wall of the cover main body 641, there is a connection pipe 651 for connecting the tip end portion of the ejection pipe 12 and the vent 641 e in a state of being attached to the main body 1. It is attached to the formation site of the mouth 641e. Further, a hook-shaped alignment member 652 for aligning the distal end portion of the ejection tube 12 and the distal end portion of the connection tube 651 is attached to each connection tube 651. In this case, by preparing a plurality of types of covers 603 having different diameters, one main body 1 is used (that is, without producing a plurality of types of main bodies 1 having different lengths of the ejection pipe 12). A plurality of types of bag filters having different inner diameters can be efficiently cleaned.
　また、図１４に示すカバー７０３を採用することもできる。この場合、このカバー７０３は、圧縮空気の噴出方向の切り替えが可能なカバーであって、カバー本体７４１および上記した固定部材３２と同様の固定部材７４２を備えて構成されている。この場合、同図に示すように、カバー本体７４１の周壁には、上記した通気口３１ｅと同様の複数（この例では１２）の通気口７４１ｅが形成されると共に、各通気口７４１ｅに隣接して通気口７４１ｅと同数（この例では１２）の通気口７４１ｆが形成されている。また、カバー本体７４１の周壁には、各通気口７４１ｆの形成部位の近傍に基端部が固定された複数（例えば２）のフィン７５１ａが取り付けられている（同図では、１つのフィン７５１ａのみを図示している）。さらに、カバー本体７４１の底部７４１ｂ（同図では上側の部位）には、本体部１に対する装着時において、ウェイト１３の２つの突起１３ａの挿通および移動が可能な平面視弧状の２つの長孔７４１ｇが形成されている。また、長孔７４１ｇの内側には、挿通された突起１３ａを押圧して本体部１に対するカバー７０３の回動を規制する板ばね７５２が配設されている。 Also, a cover 703 shown in FIG. 14 can be employed. In this case, the cover 703 is a cover capable of switching the jetting direction of compressed air, and includes a cover main body 741 and a fixing member 742 similar to the fixing member 32 described above. In this case, as shown in the drawing, a plurality of (12 in this example) vent holes 741e similar to the vent hole 31e described above are formed on the peripheral wall of the cover body 741, and adjacent to the vent holes 741e. Thus, the same number of vent holes 741f as the vent holes 741e (12 in this example) are formed. In addition, a plurality of (for example, two) fins 751a each having a base end fixed in the vicinity of a portion where each vent hole 741f is formed are attached to the peripheral wall of the cover main body 741 (in the figure, only one fin 751a is provided). Is shown). Further, the bottom portion 741b (the upper portion in the figure) of the cover main body 741 has two elongated holes 741g having an arcuate shape in a plan view in which the two protrusions 13a of the weight 13 can be inserted and moved when attached to the main body portion 1. Is formed. Further, a leaf spring 752 that presses the inserted protrusion 13a and restricts the rotation of the cover 703 relative to the main body 1 is disposed inside the elongated hole 741g.
　この場合、突起１３ａが図１４に示す位置Ｐ１に位置するようにカバー７０３を本体部１に装着した状態では、本体部１における噴出管１２の先端部が通気口７４１ｅに近接（連通）する。このため、この状態で清掃を行う際には、圧縮空気が噴出管１２の先端部から通気口７４１ｅを通ってバグフィルタ３０１の周壁３０１ｂに垂直に吹き当てられる。一方、突起１３ａが同図に示す位置Ｐ２に位置するように、カバー７０３を本体部１に対して回動させたときには、噴出管１２の先端部が通気口７４１ｆに近接（連通）する。この状態で清掃を行う際には、圧縮空気が噴出管１２の先端部から通気口７４１ｆを通って噴出され、さらにフィン７５１ａによってその向きが半径方向に直交または傾斜する向きに変更させられる。このため、この向きに変更された圧縮空気の噴出力によってカバー７０３が装着された本体部１がカバー７０３と共に回転させられる。つまり、このカバー７０３を本発明における圧縮空気噴出式の回転機構として用いることができる。 In this case, in a state where the cover 703 is mounted on the main body 1 so that the protrusion 13a is located at the position P1 shown in FIG. 14, the tip of the ejection pipe 12 in the main body 1 is close (communication) to the vent hole 741e. For this reason, when cleaning is performed in this state, compressed air is blown vertically from the distal end portion of the ejection pipe 12 through the vent hole 741e to the peripheral wall 301b of the bag filter 301. On the other hand, when the cover 703 is rotated with respect to the main body 1 so that the protrusion 13a is located at the position P2 shown in the figure, the tip of the ejection pipe 12 approaches (communicates) with the vent hole 741f. When cleaning is performed in this state, compressed air is ejected from the tip of the ejection pipe 12 through the vent hole 741f, and the direction of the fin 751a is changed to a direction orthogonal or inclined to the radial direction. For this reason, the main body 1 to which the cover 703 is attached is rotated together with the cover 703 by the jet output of the compressed air changed in this direction. That is, this cover 703 can be used as a compressed air ejection type rotating mechanism in the present invention.
　なお、図１４に示すように、カバー本体７４１の周壁の外周面における各通気口７４１ｅの形成部位近傍に基端部が固定されて、上記したフィン７５１ａとは異なる向きに延在させた（同図では、下向きに延在させた例を図示している）フィン７５１ｂを取り付けることもできる。この構成によれば、突起１３ａが位置Ｐ１に位置するようにカバー７０３を本体部１に装着した状態において、噴出管１２からの圧縮空気を様々な方向に変更させることができる。また、同図に示すように、カバー本体７４１の周壁の外周面における各通気口７４１ｅの形成部位に、同図に示すアタッチメント７５３を取り付けることにより、圧縮空気を広範囲に噴出させることができる。さらに、同図に示すように、カバー本体７４１の周壁の外周面に装着するアタッチメント７５４を備えた構成を採用することもできる。このアタッチメント７５４は、内部が中空に形成された環状体で構成され、カバー本体７４１の通気口７４１ｅの数と同数の孔が内周面に形成されると共に、通気口７４１ｅの数よりも多い数の孔が外周面に形成されている。この場合、内周面に形成された孔と通気口７４１ｅとが対向するようにこのアタッチメント７５４をカバー本体７４１に装着することで、各通気口７４１ｅから吐出する圧縮空気をより多くの孔から吐出させることができる。 As shown in FIG. 14, the base end portion is fixed in the vicinity of the formation site of each vent hole 741e on the outer peripheral surface of the peripheral wall of the cover main body 741, and extends in a direction different from the above-described fin 751a. The fins 751b can also be attached (illustrated as an example extending downward in the figure). According to this configuration, the compressed air from the ejection pipe 12 can be changed in various directions in a state where the cover 703 is mounted on the main body 1 so that the protrusion 13a is positioned at the position P1. Further, as shown in the figure, the attachment air 753 shown in the figure is attached to the formation site of each vent 741e on the outer peripheral surface of the peripheral wall of the cover main body 741, so that compressed air can be ejected over a wide range. Furthermore, as shown in the figure, a configuration including an attachment 754 attached to the outer peripheral surface of the peripheral wall of the cover main body 741 can also be adopted. The attachment 754 is formed of an annular body formed hollow inside, and the same number of holes as the number of the vent holes 741e of the cover main body 741 are formed on the inner peripheral surface, and the number larger than the number of the vent holes 741e. Are formed on the outer peripheral surface. In this case, by attaching this attachment 754 to the cover main body 741 so that the hole formed in the inner peripheral surface and the vent 741e face each other, the compressed air discharged from each vent 741e is discharged from more holes. Can be made.
　また、図１５に示す本体部１Ａのように、ナット１５ａ，１５ｂを用いてウェイト１３，１４を主管１１に対して着脱可能とした構成を採用することもできる。この構成によれば、直径の異なる複数種類のウェイト１３，１４を用意しておくことで、清掃対象のバグフィルタ３０１の内径に応じてウェイト１３，１４を容易に交換することができる。また、この本体部１Ａにおける主管１１の底部に開口部を形成し、図１６，１７に示すように底部に孔が形成されたナット１５ｃ，１５ｄを用いてウェイト１４を固定する構成を採用することもできる。この構成によれば、主管１１における底部の開口部およびナット１５ｃまたはナット１５ｄの孔を通して圧縮空気を本体部１Ａの下に向けて噴出させることができるため、バグフィルタ３０１の底部を効率的に清掃することができる。 Further, a configuration in which the weights 13 and 14 can be attached to and detached from the main pipe 11 using nuts 15a and 15b as in the main body 1A shown in FIG. According to this configuration, by preparing a plurality of types of weights 13 and 14 having different diameters, the weights 13 and 14 can be easily exchanged according to the inner diameter of the bag filter 301 to be cleaned. In addition, an opening is formed in the bottom of the main pipe 11 in the main body 1A, and the weight 14 is fixed using nuts 15c and 15d in which holes are formed in the bottom as shown in FIGS. You can also. According to this configuration, the compressed air can be ejected toward the bottom of the main body 1A through the opening at the bottom of the main pipe 11 and the hole of the nut 15c or the nut 15d, so that the bottom of the bag filter 301 is efficiently cleaned. can do.
　また、図１８に示す本体部１Ｂのように、ウェイト１３，１４に代えて羽根車１１３，１１４を備えた構成を採用することもできる。この構成では、ノズル本体１０２（本体部１Ｂ）の回転によって羽根車１１３，１１４が旋回し、この羽根車１１３，１１４の旋回に伴ってバグフィルタ３０１内の空気を開口部３０１ａ側（同図における上方側）に効率的に流動させることができる。このため、バグフィルタ３０１内に放散した粉塵等を、バグフィルタ３０１内の空気と共に外部に効率的に排出させることができる。この場合、同図に示すように、噴出管１２に代えて、周壁にフィンを設けた噴出管１２ａや、全体としてフィン状に形成した噴出管１２ｂを備えることで、バグフィルタ３０１内の空気を開口部３０１ａ側にさらに効率的に流動させることもできる。 Further, a configuration including impellers 113 and 114 instead of the weights 13 and 14 as in the main body 1B shown in FIG. In this configuration, the impellers 113 and 114 are rotated by the rotation of the nozzle main body 102 (main body portion 1B), and the air in the bag filter 301 is removed from the opening 301a side (in FIG. It is possible to efficiently flow upward). For this reason, the dust etc. which diffused in the bag filter 301 can be efficiently discharged | emitted with the air in the bag filter 301 outside. In this case, as shown in the figure, the air in the bag filter 301 can be obtained by providing a jet pipe 12a having fins on the peripheral wall instead of the jet pipe 12 and a jet pipe 12b formed in a fin shape as a whole. It can also be made to flow more efficiently to the opening 301a side.
　また、本体部１Ｂを用いるときには、上記したカバー２に代えて、図１９に示すカバー４０３を採用することもできる。このカバー４０３は、同図に示すように、カバー本体４４１および固定部材４４２を備えている。カバー本体４４１は底部（同図における上部）に鍔部４５１を備えて構成され、この鍔部４５１には、複数のフィン４５２が形成されている。また、固定部材４４２は底部（同図における下部）に鍔部４６１を備えて構成され、この鍔部４６１には、複数のフィン４６２が形成されている。このカバー４０３を備えた構成では、ノズル本体１０２（カバー４０３）の回転（同図に示す矢印Ａの向きでの回転）に伴うフィン４５２の旋回により、バグフィルタ３０１内の空気を開口部３０１ａ側に一層効率的に流動させることができる。 Further, when the main body 1B is used, a cover 403 shown in FIG. 19 can be adopted instead of the cover 2 described above. As shown in the figure, the cover 403 includes a cover main body 441 and a fixing member 442. The cover main body 441 includes a flange 451 at the bottom (upper part in the drawing), and a plurality of fins 452 are formed on the flange 451. Further, the fixing member 442 includes a flange portion 461 at the bottom (the lower portion in the figure), and the fin portion 461 is formed with a plurality of fins 462. In the configuration provided with the cover 403, the air in the bag filter 301 is turned to the opening 301a side by the rotation of the fin 452 accompanying the rotation of the nozzle body 102 (cover 403) (rotation in the direction of arrow A shown in the figure). More efficiently.
　また、カバー４０３に代えて、図２０に示すカバー５０３を採用することもできる。このカバー５０３は、同図に示すように、カバー本体５４１および固定部材５４２を備えている。カバー本体５４１は底部（同図における上部）に鍔部５５１を備えて構成され、この鍔部５５１には、複数の通気孔５５２が形成されている。また、固定部材５４２は底部（同図における下部）に鍔部５６１を備えて構成され、この鍔部５６１には、複数の通気孔５６２が形成されている。このカバー５０３を備えた構成においても、上記したカバー４０３を備えた構成と同様の効果を実現することができる。 Further, instead of the cover 403, a cover 503 shown in FIG. As shown in the figure, the cover 503 includes a cover main body 541 and a fixing member 542. The cover main body 541 includes a flange portion 551 at the bottom (upper portion in the drawing), and a plurality of vent holes 552 are formed in the flange portion 551. The fixing member 542 includes a flange portion 561 at the bottom (the lower portion in the figure), and the flange portion 561 has a plurality of ventilation holes 562 formed therein. Even in the configuration including the cover 503, the same effect as that of the configuration including the cover 403 described above can be realized.
　また、本発明におけるブラシは、上記したブラシ３１ｆ，３２ｃに限定されない。例えば、毛足の長い繊毛を備えたブラシや、数多くの帯状体を備えたブラシ８０１（図２１参照）を採用することができる。これらのブラシを備えたノズルでは、回転に伴う遠心力によって繊毛や帯状体の先端部が外周方向に広がるため、ノズル本体（カバー）の外周面と周壁との隙間の多少に拘わらず、繊毛や帯状体の先端部を周壁に確実に接触させて、粉塵等を確実に除去することができる。また、これらのブラシを配設する構成としては、種々の構成を採用することができる。例えば、カバー本体３１や固定部材３２にブラシを直接固定する構成を採用することもできる。また、筒状部材の外周面にブラシを固定し、この筒状部材をねじ込み式でカバー本体３１や固定部材３２に着脱する構成を採用することもできる。この構成によれば、毛足の長さや毛足の材質等が異なる複数種類のブラシの中から、清掃対象のバグフィルタ３０１の内径や、バグフィルタ３０１内の汚れの状態に応じて、最適なブラシを任意に選択して交換することができる。また、ブラシを固定する筒状部材の上端部または下端部を傾斜面または曲面で形成することで、清掃時のノズル本体１０２に対するバグフィルタ３０１の絡まりを防止してノズル本体１０２の移動（上下動）や回転をスムーズに行わせるガイドとして機能させることもできる。 Further, the brush in the present invention is not limited to the brushes 31f and 32c described above. For example, a brush having cilia with long hairs or a brush 801 (see FIG. 21) having many strips can be used. In the nozzles equipped with these brushes, the cilia and the tip of the band-like body expand in the outer peripheral direction due to the centrifugal force accompanying the rotation, so cilia and Dust and the like can be reliably removed by reliably bringing the tip of the belt-like body into contact with the peripheral wall. In addition, various configurations can be adopted as the configuration for disposing these brushes. For example, the structure which fixes a brush directly to the cover main body 31 or the fixing member 32 is also employable. Further, it is possible to employ a configuration in which the brush is fixed to the outer peripheral surface of the cylindrical member, and this cylindrical member is attached to and detached from the cover main body 31 and the fixing member 32 by screwing. According to this configuration, an optimal amount is selected according to the inner diameter of the bag filter 301 to be cleaned and the state of dirt in the bag filter 301 from among a plurality of types of brushes having different lengths and materials of the hair feet. The brush can be arbitrarily selected and replaced. Further, by forming the upper end or lower end of the cylindrical member for fixing the brush with an inclined surface or a curved surface, the bag filter 301 is prevented from being entangled with the nozzle body 102 during cleaning, and the nozzle body 102 is moved (moved up and down). ) And can also function as a guide for smooth rotation.
　また、図２２に示すように、上記した本体部１Ａに回転可能に接続された回転ブラシ８０２を採用することができる。この回転ブラシ８０２は、羽根車８０２ａおよび羽根車８０２ａの外周面に固定されたブラシ８０２ｂを備えて、本体部１Ａの主管１１における底部の開口部およびナット１５ｄの孔を通して噴出される圧縮空気を受けて羽根車８０２ａが旋回するように構成されている。 Further, as shown in FIG. 22, a rotating brush 802 that is rotatably connected to the main body 1A can be employed. The rotating brush 802 includes an impeller 802a and a brush 802b fixed to the outer peripheral surface of the impeller 802a, and receives compressed air ejected through the opening in the bottom of the main pipe 11 of the main body 1A and the hole of the nut 15d. The impeller 802a is configured to turn.
　また、円板状に形成した第１ウェイト１３および第２ウェイト１４を取り付けることにより、重心が中心軸に位置するようにノズル本体１０２を構成した例について上記したが、ノズル本体１０２の重心を偏心させる構成を採用することもできる。この構成によれば、回転時においてノズル本体１０２がその重心の偏心に起因して振動するため、例えば、圧縮空気の噴出開始前にその振動をバグフィルタ３０１に伝播させてバグフィルタ３０１に付着した粉塵を振るい落とすことで、その後の圧縮空気の噴出によるバグフィルタ３０１からの粉塵の除去を一層効率的に行うことができる。 Further, although the example in which the nozzle body 102 is configured so that the center of gravity is located on the central axis by attaching the first weight 13 and the second weight 14 formed in a disk shape has been described above, the center of gravity of the nozzle body 102 is eccentric. It is also possible to adopt a configuration that allows According to this configuration, since the nozzle body 102 vibrates due to the eccentricity of its center of gravity during rotation, for example, the vibration is propagated to the bag filter 301 and attached to the bag filter 301 before the start of jetting of compressed air. By dusting off the dust, it is possible to more efficiently remove the dust from the bag filter 301 by the subsequent ejection of compressed air.
　また、図２３に示すように、ノズル本体１０２における本体部１の第２ウェイト１４やカバー２の固定部材３２に装着（着脱）されるキャップ９０１を備えた構成を採用することもできる。この場合、このキャップ９０１は、半球状の内部空間９０２を有して、その内部空間９０２において移動可能なウェイト９０３（例えば、金属製の球体や、流動体）が内部空間９０２に収容されて構成されている。このキャップ９０１を備えた構成によれば、ノズル本体１０２の非回転状態においてノズル本体１０２が傾いたときに、ウェイト９０３がその傾きを修正する位置に移動するため、ノズル本体１０２を水平に維持することができる。また、ノズル本体１０２の回転状態においては、ウェイト９０３が遠心力によって上方に移動してノズル本体１０２（主管１１）の中心軸から離間した位置に位置するため、ノズル本体１０２の慣性モーメントを高めることができる結果、ノズル本体１０２の回転エネルギー（ノズル本体の回転力）を補助することができる。 Further, as shown in FIG. 23, a configuration including a cap 901 attached (detached) to the second weight 14 of the main body 1 and the fixing member 32 of the cover 2 in the nozzle main body 102 may be employed. In this case, the cap 901 has a hemispherical internal space 902, and a weight 903 (for example, a metal sphere or fluid) movable in the internal space 902 is accommodated in the internal space 902. Has been. According to the configuration provided with the cap 901, when the nozzle body 102 is tilted when the nozzle body 102 is not rotated, the weight 903 moves to a position for correcting the tilt, so that the nozzle body 102 is kept horizontal. be able to. Further, in the rotating state of the nozzle body 102, the weight 903 moves upward by centrifugal force and is positioned away from the central axis of the nozzle body 102 (main pipe 11), so that the moment of inertia of the nozzle body 102 is increased. As a result, the rotational energy of the nozzle body 102 (rotational force of the nozzle body) can be assisted.
　また、空気供給管１１０を送り出す際の送り出し長さ、および空気供給管１１０を引き上げる際の引き上げ長さが、所定の長さに達する毎にその旨を報知する、つまりノズル本体１０２の上下方向への移動距離を報知する報知部を昇降装置１０７に設けることもできる。この場合、報知部の報知手段としては、音でその旨を報知する音声発生手段や、光でその旨を報知する発光手段を採用することができる。また、空気供給管１１０の送り出し長さおよび引き上げ長さに代えて（または、これらと共に）、空気供給管１１０の送り出し速度および引き上げ速度、つまりノズル本体１０２の上下方向への移動速度を上記の各種の手段で報知する報知部を昇降装置１０７に設けることもできる。この構成によれば、バグフィルタ３０１の内部に挿入したノズル本体１０２の位置や移動速度を作業者が容易に把握することができるため、作業効率を十分に向上させることができる。また、モーター７２によってローラー７３ａ，７３ｂを回転させる電動式の昇降装置１０７に代えて、ローラー７３ａ，７３ｂを手動で回転させる手動式の昇降装置を採用することもできる。また、空気供給管１１０の送り出しおよび引き上げを行う構成に代えて、ノズル本体１０２にワイヤー等を接続して、そのワイヤー等を電動または手動で巻き取る（または、巻き戻す）ことによってノズル本体１０２（ノズル本体１０２に取り付けられた各構成要素を含む）の昇降を行う昇降装置を採用することもできる。 Further, when the delivery length when the air supply pipe 110 is sent out and the lift length when the air supply pipe 110 is pulled up reach a predetermined length, this is notified, that is, in the vertical direction of the nozzle body 102. It is also possible to provide an elevating device 107 with an informing unit for informing the moving distance. In this case, as the notification means of the notification section, it is possible to adopt a sound generation means that notifies that fact by sound, or a light emitting means that notifies that fact by light. Further, instead of (or together with) the feed length and the pull-up length of the air supply pipe 110, the feed speed and the pull-up speed of the air supply pipe 110, that is, the moving speed of the nozzle body 102 in the vertical direction are changed to the above-mentioned various types. The raising / lowering device 107 can also be provided with a notifying unit for notifying by this means. According to this configuration, since the operator can easily grasp the position and moving speed of the nozzle body 102 inserted into the bag filter 301, the working efficiency can be sufficiently improved. Further, instead of the electric lifting device 107 that rotates the rollers 73a and 73b by the motor 72, a manual lifting device that manually rotates the rollers 73a and 73b may be employed. Further, instead of a configuration in which the air supply pipe 110 is sent out and pulled up, a nozzle or the like is connected to a nozzle body 102, and the wire or the like is electrically or manually wound (or rewound) so that the nozzle body 102 ( It is also possible to employ a lifting device that lifts and lowers each component (including each component attached to the nozzle body 102).
　さらに、上昇させたノズルシステム１０１がキャップ１０８の本体部８１内に位置したときにオン状態に移行するスイッチを本体部８１内に設けると共に、そのスイッチがオン状態に移行するときに圧縮空気の供給経路を遮断する電磁弁をコンプレッサと空気供給管１１０との間に配設するとことにより、ノズルシステム１０１が上昇した際に圧縮空気の供給を自動的に停止させる構成を採用することもできる。 Further, a switch that is turned on when the raised nozzle system 101 is positioned in the main body 81 of the cap 108 is provided in the main body 81, and compressed air is supplied when the switch is turned on. It is also possible to employ a configuration in which the supply of compressed air is automatically stopped when the nozzle system 101 rises by disposing an electromagnetic valve that cuts off the path between the compressor and the air supply pipe 110.
　また、図２４に示すジョイント８０３を用いて、圧縮空気を供給する構成を採用することもできる。この場合、ジョイント８０３は、一端部側（同図における上端部側）に２本の空気供給管１１０を連結可能に構成され、他端部側（同図における下端部側）がロータリージョイント１０６に連結可能に構成されている。この場合、このジョイント８０３を用いることにより、２本の空気供給管１１０で圧縮空気を供給することができるため、エアコンプレッサの能力が低い場合であっても、そのエアコンプレッサを２台用いることで、十分な圧力および量の圧縮空気をノズル本体１０２に供給することができる。 Further, a configuration in which compressed air is supplied using a joint 803 shown in FIG. In this case, the joint 803 is configured so that two air supply pipes 110 can be connected to one end side (upper end side in the figure), and the other end side (lower end side in the figure) is connected to the rotary joint 106. It is configured to be connectable. In this case, since the compressed air can be supplied by the two air supply pipes 110 by using the joint 803, even if the capacity of the air compressor is low, two air compressors can be used. A sufficient pressure and amount of compressed air can be supplied to the nozzle body 102.
　また、キャップ１０８の鍔部８２の下（嵌合片８６）に挿入する筒状のスペーサを備えた構成を採用することもできる。この場合、バグフィルタ３０１の開口部３０１ａ側に挿入する挿入部分の外径の異なるスペーサを複数用意しておき、これらを付け替えることで、内径の異なる各種のバグフィルタ３０１にスペーサを介してキャップ１０８を装着することができる。また、高さの異なるスペーサを複数用意しておき、これらを付け替えることで、バグフィルタ３０１の開口部３０１ａからキャップ１０８の頂部（本体部８１の底面）までの高さを、作業者の身長に合わせて作業効率のよい高さに任意に変更することができる。また、清掃が終了したバグフィルタ３０１の内部への埃の侵入を防止するための開口部３０１ａを閉塞するキャップを備えた構成を採用することもできる。また、図２５に示す流量調整管８０４を本体部１における主管１１の開口部１１ａ側に挿入して、主管１１内の通気経路を変更する（絞る）ことによって圧縮空気の流量を調整する構成を採用することもできる。この構成によれば、噴出管１２からの圧縮空気の噴出量や噴出圧力を容易に変更することができると共に、ノズル本体１０２の回転速度を容易に変更することができる。また、図２６に示すように、清掃作業中における空気供給管１１０の折れ曲がりを防止するためのガイド部材８０５を備えた構成を採用することもできる。また、ガイド部材８０５はキャップ１０８を昇降装置１０７およびノズル本体１０２と共に移動させるときの取っ手として活用することもできる。なお、加圧された気体の一例としての圧縮空気を用いる例について上記したが、本発明における気体には、空気以外の各種の気体が含まれる。 Further, it is also possible to adopt a configuration including a cylindrical spacer that is inserted under the flange portion 82 (fitting piece 86) of the cap 108. In this case, a plurality of spacers having different outer diameters of insertion portions to be inserted into the opening 301a side of the bag filter 301 are prepared, and by replacing them, various kinds of bag filters 301 having different inner diameters are inserted into the cap 108 via the spacers. Can be worn. Also, by preparing a plurality of spacers having different heights and replacing them, the height from the opening 301a of the bag filter 301 to the top of the cap 108 (the bottom surface of the main body 81) is adjusted to the height of the operator. In addition, the height can be arbitrarily changed to a high working efficiency. Moreover, the structure provided with the cap which obstruct | occludes the opening part 301a for preventing the penetration | invasion of the dust to the inside of the bag filter 301 which finished cleaning can also be employ | adopted. 25 is inserted into the opening 11a side of the main pipe 11 in the main body 1 and the flow path of the compressed air is adjusted by changing (squeezing) the ventilation path in the main pipe 11. It can also be adopted. According to this configuration, it is possible to easily change the jet amount and jet pressure of the compressed air from the jet pipe 12, and it is possible to easily change the rotation speed of the nozzle body 102.
