Description
【０００１】[0001]
本考案は、例えば工場の作業場における作業ヒュームを吸引し、吸引したヒュ ームに荷電させて塵埃を補集する静電式電気集塵機に関する。 The present invention relates to an electrostatic precipitator that sucks working fumes in a factory workplace, for example, and charges the sucked fume to collect dust.
【０００２】[0002]
一般に、溶接ヒューム等の作業ヒュームを吸引する場合、なるべく作業ヒュー ウの発生箇所の近くで吸引すれば少ない排風量で経済的に集塵することができる ため、例えば図１に示すごとく可搬形の静電式電気集塵機が提言されている。 Generally, when sucking working fumes such as welding fumes, it is possible to economically collect dust with a small amount of exhausted air by sucking as close as possible to the place where the working fumes are generated. For example, as shown in FIG. Electrostatic dust collectors have been proposed.
【０００３】 図１において、１は集塵用の静電フィルタ構造体、２は静電フィルタ構造体１ が挿入および取り出し自在な開口部を有する本体ケース、３は静電フィルタ構造 体１に高電圧を供給するための高電圧発生装置、４は作業ヒュームを吸引するた めの吸引口、５は吸引口４に連結した吸引ホース、６は吸引ホース５に連結し、 本体ケース２に作業ヒュームを誘導する誘導路、７は静電フィルタ構造体１の下 流側、即ち誘導路６に対して静電フィルタ構造体１を跨いだ位置に配設された吸 引用のファン、８は除塵後の清浄な空気を排出する排出口、９は静電フィルタ構 造体１を本体ケース２に対して出し入れするために使用される扉、１０は移動用 の車輪、１１は本体ケース２を支持する安定脚である。In FIG. 1, 1 is an electrostatic filter structure for collecting dust, 2 is a main body case having an opening through which the electrostatic filter structure 1 can be inserted and removed, and 3 is an electrostatic filter structure 1. High voltage generator for supplying voltage, 4 is a suction port for sucking the working fume, 5 is a suction hose connected to the suction port 4, 6 is a suction hose 5, and the working fume is attached to the main body case 2. A guide path for inducing the exhaust gas, 7 is a suction fan disposed on the downstream side of the electrostatic filter structure 1, that is, a position across the electrostatic filter structure 1 with respect to the guide path 6, and 8 is after dust removal. For discharging the clean air, 9 is a door used for putting the electrostatic filter structure 1 in and out of the body case 2, 10 is a wheel for movement, 11 is a body case 2 It has stable legs.
【０００４】 上記静電式電気集塵機において、静電フィルタ構造体１は一段または多段に装 填され、静電フィルタ構造体１に高電圧が印加されると、作業ヒュームの粉塵が 静電気の作用で補集される。しかし、補集した塵埃量が増加すると集塵効率が低 下するため、定期的に静電フィルタ構造体１を浄化する必要がある。In the above electrostatic type electrostatic precipitator, the electrostatic filter structure 1 is packed in one or more stages, and when a high voltage is applied to the electrostatic filter structure 1, the dust of the working fume is electrostatically affected. Collected. However, as the amount of collected dust increases, the dust collection efficiency decreases, so it is necessary to clean the electrostatic filter structure 1 regularly.
【０００５】 このため、静電フィルタ構造体１は、例えば図２に示すごとく、荷電用のイオ ン電極群２０と補集用の集塵電極群２６とが一体的に形成され、本体ケース２に 対して着脱し易い構造になっている。Therefore, in the electrostatic filter structure 1, for example, as shown in FIG. 2, the ion electrode group 20 for charging and the dust collecting electrode group 26 for collecting are integrally formed, and the main body case 2 It has a structure that makes it easy to put on and take off.
【０００６】 即ち図２において、イオン電極群２０は多数の放電電極２１と多数の放電用負 電極板２２とから成り、放電電極２１の両端は放電電極支持体２３により支持さ れ、放電電極支持体２３は絶縁固定部材２４Ａ、２４Ｂにより枠体１２に電気絶 縁的に固定されている。That is, in FIG. 2, the ion electrode group 20 is composed of a large number of discharge electrodes 21 and a large number of discharge negative electrode plates 22, and both ends of the discharge electrodes 21 are supported by a discharge electrode support member 23. The body 23 is electrically fixed to the frame body 12 by insulating fixing members 24A and 24B.
【０００７】 一方、集塵電極群２６は多数の集塵用負電極板２７と多数の集塵用正電極板２ ８とから成り、集塵電極群支持体２９と枠体１２により支持され、かつ集塵用負 電極板２７は絶縁固定部材３２により集塵電極群支持体２９に対して電気絶縁的 に固定されている。また、集塵用正電極板２８を電気的に導通して支持する集塵 電極群支持体２９と集塵用正電極板２８とは、絶縁固定部材３０Ａ、３０Ｂ、お よび３１を介して枠体１２に対して電気絶縁的に固定されている。On the other hand, the dust collecting electrode group 26 includes a large number of dust collecting negative electrode plates 27 and a large number of dust collecting positive electrode plates 28, and is supported by a dust collecting electrode group support 29 and a frame 12. Further, the dust collecting negative electrode plate 27 is electrically insulated from the dust collecting electrode group support 29 by the insulating fixing member 32. In addition, the dust collecting electrode group support 29 that electrically supports the dust collecting positive electrode plate 28 and supports it, and the dust collecting positive electrode plate 28 are framed via the insulating fixing members 30A, 30B, and 31. It is fixed to the body 12 in an electrically insulating manner.
【０００８】 放電電極支持体２３および集塵電極群支持体２９には、高電圧発生装置３から 供給される高電圧を受電するための受電部２５、３３が配設されて、放電電極２ １および集塵用正電極板２８に夫々高電圧が印加される。一方、放電用負電極板 ２２および集塵用負電極板２７は夫々枠体１２と電気的に導通され、かつこの枠 体１２は接地３４されている。The discharge electrode support 23 and the collection electrode group support 29 are provided with power receiving units 25 and 33 for receiving the high voltage supplied from the high voltage generator 3, and the discharge electrode 21 A high voltage is applied to the dust collecting positive electrode plate 28. On the other hand, the discharging negative electrode plate 22 and the dust collecting negative electrode plate 27 are electrically connected to the frame body 12, and the frame body 12 is grounded.
【０００９】 今、受電部２５を通して放電電極２１と放電用負電極板２２との間に数ＫＶの 高電圧が印加されると、放電電極２１からコロナ放電が発生し、イオン電極群２ ０を通過する塵埃粒子を正イオンに荷電する。また、静電フィルタ構造体１は集 塵電極群２６が空気流の下流側になるよう本体ケース２に装填されおり、イオン 電極群２０で正イオンに荷電した塵埃粒子は集塵電極群２６側へと移行する。一 方、受電部３３を通して集塵用正電極板２８と集塵用負電極板２７との間に数Ｋ Ｖの高電圧が印加されているため、正イオンに荷電した塵埃粒子は集塵用正電極 板２８に対して反発し、急速に集塵用負電極板２７に吸着し補集される。Now, when a high voltage of several KV is applied between the discharge electrode 21 and the discharge negative electrode plate 22 through the power receiving unit 25, corona discharge is generated from the discharge electrode 21 and the ion electrode group 20 is discharged. The passing dust particles are charged with positive ions. The electrostatic filter structure 1 is loaded in the main body case 2 so that the dust collecting electrode group 26 is located on the downstream side of the air flow, and the dust particles charged with positive ions in the ion electrode group 20 are on the dust collecting electrode group 26 side. Transition to. On the other hand, since a high voltage of several KV is applied between the dust collecting positive electrode plate 28 and the dust collecting negative electrode plate 27 through the power receiving unit 33, dust particles charged with positive ions are used for collecting dust. It repels the positive electrode plate 28 and is rapidly adsorbed by the dust collecting negative electrode plate 27 to be collected.
【００１０】 上記静電フィルタ構造体１は、図３乃至図５に示されるごとく、案内板４０、 ４１をガイドとして、本体ケース２の開口部４２に対して挿入および取り出し自 在に形成され、本体ケース２に装填された状態で扉９を閉じると、案内板４０、 ４１、ストッパ４３、および扉９により拘束される。なお、静電フィルタ構造体 １が本体ケース２に対して着脱し易いようにするために、案内板４０、４１と静 電フィルタ構造体１には水平方向、即ちＸ方向に間隙４６を有する。As shown in FIGS. 3 to 5, the electrostatic filter structure 1 is formed so as to be inserted into and removed from the opening 42 of the main body case 2 with the guide plates 40 and 41 as guides. When the door 9 is closed while it is loaded in the main body case 2, it is constrained by the guide plates 40, 41, the stopper 43, and the door 9. In order to make the electrostatic filter structure 1 easily attachable to and detachable from the body case 2, the guide plates 40 and 41 and the electrostatic filter structure 1 have a gap 46 in the horizontal direction, that is, the X direction.
【００１１】 また、放電電極の受電部２５および集塵用正電極板の受電部３３に夫々対応す る位置に板バネ状の給電体４４Ａ、４４Ｂが配設され、給電体４４Ａ、４４Ｂは 固定ビス４８により絶縁体４５に係止されて、本体ケース２に対して絶縁状態に 取り付けられている。Further, plate-spring-shaped power feeding members 44A and 44B are arranged at positions corresponding to the power receiving unit 25 of the discharge electrode and the power receiving unit 33 of the positive electrode plate for collecting dust, and the power feeding members 44A and 44B are fixed. It is locked to the insulator 45 by the screw 48 and is attached to the body case 2 in an insulated state.
【００１２】 板バネ状の給電体４４Ａ、４４Ｂの自由端部とは反対方向、即ちＹ1 方向には 夫々導体４７、４７が接続されて、導体４７を介して高電圧発生装置３により発 生した高電圧が板バネ状の給電体４４Ａ、４４Ｂに供給される。即ち、静電フィ ルタ構造体１を本体ケース２に挿入した時に、給電体４４Ａ、４４Ｂが夫々受電 部２５、３３に弾接して、静電フィルタ構造体１に高電圧が印加される。Conductors 47, 47 are connected in the opposite direction to the free ends of the leaf-spring-shaped power feeders 44 A, 44 B, that is, in the Y 1 direction, and are generated by the high voltage generator 3 via the conductor 47. The generated high voltage is supplied to the leaf-spring-shaped power feeding bodies 44A and 44B. That is, when the electrostatic filter structure 1 is inserted into the main body case 2, the power feeders 44A and 44B elastically contact the power receiving portions 25 and 33, respectively, and a high voltage is applied to the electrostatic filter structure 1.
【００１３】 上記構成の静電式電気集塵機において、静電フィルタ構造体１の本体ケース２ に対する位置精度が余りよくないため、移動距離が大きくとれる板バネが用いら れ、かつ、板バネの材質としては接点材料という観点から銅または銅合金が用い られている。In the electrostatic electrostatic precipitator having the above-mentioned configuration, since the positional accuracy of the electrostatic filter structure 1 with respect to the main body case 2 is not so good, a leaf spring that allows a large movement distance is used, and a material of the leaf spring is used. For this purpose, copper or copper alloy is used from the viewpoint of contact material.
【００１４】[0014]
ところで、静電フィルタ構造体１を本体ケース１に挿入する際、静電フィルタ 構造体１は間隙４６だけ水平方向に移動自在であるため、受電部２５、３３が板 バネ状給電体４４Ａ、４４Ｂを押しのける時に、受電部と板バネ状給電部がひっ かかり、この状態で静電フィルタ構造体１を無理に挿入すると板バネの耐力以上 の力が板バネに作用し、板バネが変形して、正常な給電がおこなえなくなるとい う欠点があった。 By the way, when the electrostatic filter structure 1 is inserted into the main body case 1, since the electrostatic filter structure 1 is movable in the horizontal direction by the gap 46, the power receiving portions 25 and 33 are the leaf spring-shaped power supply members 44A and 44B. When pushing away, the power receiving part and the leaf spring-like power feeding part are caught, and if the electrostatic filter structure 1 is forcibly inserted in this state, a force greater than the proof stress of the leaf spring acts on the leaf spring, and the leaf spring is deformed. However, there was a drawback that normal power supply could not be performed.
【００１５】 また、集塵する作業ヒューム中に腐食性ガスを含有している場合には、銅系の 板バネ状給電体では銅が腐食し、給電体としての耐久性が著しく低下する。この ため、電気メッキ等の表面処理を施す必要がある。しかし、静電フィルタ構造体 １の着脱を反復するにしたがって、受電部と接する部分の表面処理層が剥がれ、 これにより銅が腐食してしまい、耐久力の低下に伴い板バネの変形が避けられな かった。In addition, when corrosive gas is contained in the working fume that collects dust, copper is corroded in the copper-based leaf spring-like power feeding body, and durability as the power feeding body is significantly reduced. Therefore, it is necessary to perform surface treatment such as electroplating. However, as the electrostatic filter structure 1 is repeatedly attached and detached, the surface treatment layer in the portion in contact with the power receiving portion is peeled off, which causes corrosion of the copper and deformation of the leaf spring is avoided due to deterioration in durability. It wasn't.
【００１６】 本考案は上述の問題に鑑みてなされたもので、その目的は、板バネ状給電体の 耐久性および耐食性を向上させ、経年的に使用できる静電式電気集塵機を提供す ることである。The present invention has been made in view of the above problems, and an object thereof is to provide an electrostatic precipitator that improves durability and corrosion resistance of a leaf spring-shaped power feeder and can be used over the years. Is.
【００１７】[0017]
上記目的を達成するため、本考案は、イオン電極群と集塵電極群とを取り付け た静電フィルタ構造体が、集塵機本体ケースの開口部に対して挿入および取り出 し自在に形成され、静電フィルタ構造体を装填時に、前期本体ケースの開口部内 に張り出されている夫々の板バネ状の給電体を介して前期電極群に高電圧が印加 される静電式電気集塵機に適用される。 その特徴とするところは、本第１の考案は、板バネ状の給電体をバネ用ステン レス鋼により形成したことである。さらに、本第２の考案は、第１の考案に加え て、板バネ状の給電体を自由端部が集塵機本体ケースの開口部の底部側となるよ う配設したことである。 In order to achieve the above object, the present invention has an electrostatic filter structure in which an ion electrode group and a dust collecting electrode group are attached so that it can be inserted into and removed from the opening of the dust collector body case, and It is applied to the electrostatic precipitator in which a high voltage is applied to the electrode group through the respective leaf spring-shaped power feeds that are projected into the opening of the main case when the electric filter structure is loaded. . The characteristic of the present invention is that the first spring-shaped feeder is made of stainless steel for spring. Further, in the second invention, in addition to the first invention, a leaf-spring-shaped power feeding body is arranged so that the free end is on the bottom side of the opening of the dust collector body case.
【００１８】[0018]
以下、本考案を図示の実施例により詳細に説明する。なお、静電式電気集塵機 の全体的な構成は図１に示されると同様に１〜１１の各部から成り、１２乃至４ ６も図２乃至図４と同様であるため詳細説明は省略する。 Hereinafter, the present invention will be described in detail with reference to illustrated embodiments. The overall structure of the electrostatic electrostatic precipitator is made up of the respective parts 1 to 11 as shown in FIG. 1, and 12 to 46 are also the same as those in FIGS.
【００１９】 図６において、板バネ状の給電体４４Ａ、４４Ｂは放電電極の受電部２５およ び集塵用正電極板の受電部３３に夫々対応する位置に配設され、かつ板バネ状の 給電体４４Ａ、４４Ｂの自由端部が本体ケース２の開口部４２の底部側となるよ うに、固定ビス４８により支持されている。なお、給電体４４Ａ、４４Ｂは絶縁 体４５により係止されて、本体ケース２に対して電気絶縁的に取り付けられてい る。In FIG. 6, leaf-spring-shaped power supply members 44 A and 44 B are arranged at positions corresponding to the power-receiving portion 25 of the discharge electrode and the power-receiving portion 33 of the positive electrode plate for collecting dust, and are in the leaf-spring shape. The feeders 44A and 44B are supported by fixing screws 48 so that the free ends thereof are on the bottom side of the opening 42 of the main body case 2. The feeders 44A and 44B are locked by an insulator 45 and electrically attached to the body case 2.
【００２０】 板バネ状の給電体４４Ａ、４４Ｂはバネ用ステンレス鋼により形成され、板バ ネ状の給電体４４Ａ、４４Ｂの自由端部とは反対方向、即ちＹ2 方向に夫々導体 ４７、４７が接続されて、この導体４７を介して高電圧発生装置３により発生し た高電圧が板バネ状の給電体４４Ａ、４４Ｂに供給される。The plate spring-shaped power feeding members 44A and 44B are made of stainless steel for springs, and conductors 47 and 47 are formed in the direction opposite to the free ends of the plate blade-shaped power feeding members 44A and 44B, that is, in the Y 2 direction, respectively. Are connected to each other, and the high voltage generated by the high voltage generator 3 is supplied to the leaf-spring-shaped power feeders 44A and 44B through the conductor 47.
【００２１】 上記構成において、図６に示されるごとく、静電フィルタ構造体１が本体ケー ス２に挿入される時、放電電極の受電部２５および集塵用正電極板の受電部３３ は板バネ状の給電体４４Ａ、４４Ｂとこすれながら接触し、また板バネ状の給電 体４４Ａ、４４ＢをＸ1 方向に押しのけるように移動して、板バネ状の給電体４ ４Ａ、４４Ｂは自由端部が時計方向に位置変位する。静電フィルタ構造体１が挿 入された位置１Ａにおいて、板バネ状の給電体４４Ａ、４４Ｂが夫々放電電極の 受電部２５および集塵用正電極板の受電部３３に弾接されて、静電フィルタ構造 体１に高電圧が印加される。In the above structure, as shown in FIG. 6, when the electrostatic filter structure 1 is inserted into the main body case 2, the power receiving portion 25 of the discharge electrode and the power receiving portion 33 of the positive electrode plate for collecting dust are separated from each other. The plate-shaped power supply members 44A and 44B are in contact with each other while rubbing, and the plate-spring-shaped power supply members 44A and 44B are moved in the X 1 direction so that the plate-spring-shaped power supply members 44A and 44B are free ends. Moves in the clockwise direction. At the position 1A where the electrostatic filter structure 1 is inserted, the leaf-spring-shaped power feeding members 44A and 44B are elastically contacted with the power receiving unit 25 of the discharge electrode and the power receiving unit 33 of the positive electrode plate for dust collection, respectively, and the static electricity is discharged. A high voltage is applied to the electric filter structure 1.
【００２２】 上記構成の静電式電気集塵機の場合、静電フィルタ構造体１が本体ケース２に 挿入される途中においては、即ち詳しくは放電電極の受電部２５または集塵用正 電極板の受電部３３の一端が板バネ状の給電体４４Ａまたは４４Ｂに当接した時 に、放電電極の受電部２５または集塵用正電極板の受電部３３の一端と板バネ状 の給電体４４Ａまたは４４Ｂがひっかかる状態となる。In the case of the electrostatic electrostatic precipitator having the above-described configuration, during the insertion of the electrostatic filter structure 1 into the main body case 2, that is, in detail, the power receiving portion 25 of the discharge electrode or the positive electrode plate for dust collection When one end of the portion 33 comes into contact with the leaf spring-shaped power feeding body 44A or 44B, one end of the power receiving portion 25 of the discharge electrode or the dust receiving positive electrode plate 33 and the leaf spring-shaped power feeding body 44A or 44B. Will be caught.
【００２３】 しかし板バネ状の給電体４４Ａ、４４Ｂは夫々自由端部が静電フィルタ構造体 １の挿入方向にフリーであるため、静電フィルタ構造体１を挿入するにつれて板 バネ状の給電体４４Ａ、４４Ｂが引っ張られる状態となる。However, since the free ends of the plate-spring-shaped power feeders 44A and 44B are free in the insertion direction of the electrostatic filter structure 1, the leaf-spring-shaped power feeders are inserted as the electrostatic filter structure 1 is inserted. 44A and 44B are pulled.
【００２４】 すなわち、受電部２５、３３の挿入方向への移動に伴い、板バネ状の給電体４ ４Ａ、４４Ｂの自由端部は時計方向に位置変位する。このため、板バネ状の給電 体４４Ａ、４４Ｂは変形することなく、受電部２５、３３とは反対方向に容易に 押しのけられ、静電フィルタ構造体１が本体ケース２に挿入できる。That is, with the movement of the power receiving portions 25 and 33 in the insertion direction, the free ends of the leaf spring-shaped power feeding bodies 44A and 44B are displaced in the clockwise direction. For this reason, the leaf-spring-shaped power feeding members 44A and 44B are easily deformed in the direction opposite to the power receiving units 25 and 33 without being deformed, and the electrostatic filter structure 1 can be inserted into the main body case 2.
【００２５】 さらに、バネ用ステンレス鋼の機械的強度は銅に比べて４倍以上であって、こ のバネ用ステンレス鋼より成る板バネ状の給電体４４Ａ、４４Ｂは変形しにくい ため、常に安定した給電をおこなうことができる。Further, the mechanical strength of stainless steel for springs is four times or more that of copper, and the plate-spring-shaped power feeding members 44A and 44B made of stainless steel for springs are not easily deformed, so that they are always stable. It is possible to supply power.
【００２６】 また、バネ用ステンレス鋼は銅に比べて耐食性に優れているため、特別に電気 メッキ等の表面処理を施すことなく腐食性ガス雰囲気中で使用することができる 。このため、腐食性ガスを含有した作業ヒュームを吸引する場合でも、バネ用ス テンレス鋼より成る板バネ状の給電体４４Ａ、４４Ｂは腐食することなく、初期 の耐久力が維持できる。Further, since stainless steel for springs is superior in corrosion resistance to copper, it can be used in a corrosive gas atmosphere without special surface treatment such as electroplating. Therefore, even when sucking the working fume containing the corrosive gas, the leaf spring-shaped power feeding members 44A and 44B made of stainless steel for spring are not corroded and the initial durability can be maintained.
【００２７】 一方、上記構成の静電式電気集塵機において、放電電極２１に印加する電圧は ８ＫＶ程度の直流であり、また集塵用正電極板２８に印加する電圧は４ＫＶ程度 の直流であるが、静電フィルタ構造体１自体の電気抵抗は１００ＭΩ以上と大き く、流れる電流は２ｍＡ以下と微少である。ところで、バネ用ステンレス鋼は銅 に比べて電気抵抗が約３０倍以上であるが、電流が２ｍＡ以下と微少なため、板 バネ状の給電体４４Ａ、４４Ｂの抵抗発熱も微少であり通電上問題はない。On the other hand, in the electrostatic electrostatic precipitator having the above structure, the voltage applied to the discharge electrode 21 is a direct current of about 8 KV, and the voltage applied to the positive electrode plate 28 for dust collection is a direct current of about 4 KV. The electric resistance of the electrostatic filter structure 1 itself is as large as 100 MΩ or more, and the flowing current is as small as 2 mA or less. By the way, the electric resistance of stainless steel for springs is about 30 times or more compared to that of copper, but the electric current is 2 mA or less, which is very small. There is no.
【００２８】 また、静電フィルタ構造体１自体の電気抵抗が１００ＭΩと大きいため、板バ ネ状の給電体４４Ａ、４４Ｂの電気抵抗が多少大きくなっても、集塵効率が殆ど 低下することはない。Further, since the electric resistance of the electrostatic filter structure 1 itself is as high as 100 MΩ, even if the electric resistance of the plate-shaped power feeding members 44A and 44B becomes a little large, the dust collection efficiency is hardly lowered. Absent.
【００２９】 上記のごとく、板バネ状の給電体４４Ａ、４４Ｂの自由端部が本体ケース２の 開口部の底部側となるよう配設すれば、静電フィルタ構造体１の挿入および取出 時に板バネ状の給電体４４Ａ、４４Ｂが変形することがないため好ましい。As described above, if the free ends of the plate-spring-shaped power feeding members 44 A and 44 B are arranged so as to be on the bottom side of the opening of the main body case 2, the plate is inserted and removed when the electrostatic filter structure 1 is inserted and removed. The spring-shaped power feeding bodies 44A and 44B are not deformed, which is preferable.
【００３０】 これにも拘らず板バネ状の給電体４４Ａ、４４Ｂの自由端部を本体ケース２の 開口方向とすることができる。この場合、板バネ状の給電体４４Ａ、４４Ｂは機 械的強度の大きいバネ用ステンレスであるため、受電部２５、３３と板バネ状の 給電体４４Ａ、４４Ｂとが当接後、更に受電部２５、３３を挿入すると機械強度 の大きい板バネ状の給電体４４Ａ、４４Ｂは容易に外側に位置変位する。すなわ ち、板バネ状の給電体４４Ａ、４４Ｂが従来のごとく、容易に変形するというこ とがなく、安定な給電をおこなうことができる。Despite this, the free ends of the plate spring-shaped power feeding bodies 44A and 44B can be oriented in the opening direction of the main body case 2. In this case, since the plate spring-shaped power supply members 44A and 44B are made of stainless steel for springs having high mechanical strength, after the power receiving units 25 and 33 come into contact with the plate spring-shaped power supply units 44A and 44B, the power receiving unit is further When 25 and 33 are inserted, the leaf spring-shaped power feeding bodies 44A and 44B having high mechanical strength are easily displaced to the outside. That is, it is possible to perform stable power supply without the plate spring-shaped power supply bodies 44A and 44B being easily deformed as in the conventional case.
【００３１】 勿論、静電フィルタ構造体１を本体ケース２に挿入する際、受電部２５、３３ に対して機械的強度の大きい板バネ状の給電体４４Ａ、４４Ｂが容易に外側に位 置変位して、スムーズに静電フィルタ構造体１を挿入できるため、静電フィルタ 構造体の挿入作業を迅速に行うことができる。Of course, when the electrostatic filter structure 1 is inserted into the main body case 2, the leaf-spring-shaped power feeders 44A and 44B having large mechanical strength with respect to the power receiving portions 25 and 33 are easily displaced to the outside. Since the electrostatic filter structure 1 can be smoothly inserted, the electrostatic filter structure can be inserted quickly.

以上の説明で明らかなように、本考案によれば、静電式電気集塵機の静電フィ ルタ構造体に高電圧を印加させる板バネ状の給電体の耐久力が向上し、繰り返し 静電フィルタ構造体を集塵機本体ケースに着脱しても板バネ状の給電体が変形す ることなく所望の作業が行うことができる。 As is clear from the above description, according to the present invention, the durability of the leaf spring-shaped power feeding body that applies a high voltage to the electrostatic filter structure of the electrostatic precipitator is improved, and the electrostatic filter is repeatedly used. Even if the structure is attached to or detached from the dust collector body case, the desired work can be performed without the leaf spring-shaped power feeding body being deformed.
【００３３】 また、腐食性ガスを含有した作業ヒュームを吸引する場合においても、板バネ 状の給電体が腐食する恐れがなく、初期の耐久力が維持できる。Further, even when the working fume containing the corrosive gas is sucked, there is no fear that the leaf spring-shaped power supply body is corroded, and the initial durability can be maintained.
【００３４】 さらに、静電フィルタ構造体を集塵機本体ケースに挿入する際、静電フィルタ 構造体の受電部に対して機械的強度の大きい板バネ状の給電体が容易に外側に位 置変位して、スムーズに静電フィルタ構造体を挿入できるため、静電フィルタ構 造体の挿入作業を迅速に行うことができる。Furthermore, when the electrostatic filter structure is inserted into the dust collector main body case, the leaf-spring-shaped power feeding body having high mechanical strength is easily displaced to the outside with respect to the power receiving portion of the electrostatic filter structure. Since the electrostatic filter structure can be smoothly inserted, the electrostatic filter structure can be inserted quickly.
